Conveyor belt cleaner

Abstract: A conveyor belt cleaner mounted on a transverse support member including an arm extending from a mounting bracket and a belt cleaner blade secured on the arm. A positioning arrangement is provided between the arm and the cleaner blade to allow the blade to rotate about the central axis of the arm within predetermined limits in either direction so as to allow the scraping edge of the cleaner blade to align with the surface of the conveyor belt being cleaned. A nut and a resilient washer are provided to secure the blade against a collar. An alternative securement includes a pin-and-slot connection which allows the same rotative action of the blade relative to the arm and having multiple seals against the entrance of dirt into the connection.

In the closed position the lid (11) encloses the upper collar part (39). To the inside of a lid front side (17) an inner lid flap (32) is fixed which only in the area of a (longer) lateral edge (50) has a recess (52) that ensures an interlocking by positive fit with a ridge (42) in the area of a collar front side (36) when the lid is closed.

Method and apparatus for lateral drilling in oil and gas wells

Abstract: A method and associated apparatus for lateral drilling in an oil and/or gas well involving either stopping the drilling or temporarily cementing in a plug in the existing well bore at the desired location for deviation. A tight radius of curvature is then rotary drilled by use of a flexible drilling collar made up of a series of short drill string sections interconnected by universal joints that terminate within an eccentric collar on the final drill string section. The eccentric collar is equipped with a sidewall engaging means to hold the eccentric collar from rotating during rotary drilling. A flexible collar (e.g., ball and socket) extending outwardly and downwardly from the far end of the final drill string section passing through the eccentric collar connects to a drill bit collar and rotary drill bit. A stabilizer/reamer of essentially the same size or slightly larger diameter than the drill bit surrounds the drill bit collar, thus producing a fulcrum for tilting the drill bit perpendicular to the well bore. The eccentric collar on the last drill string section that engages the well bore forces the deflection of the drill bit about the fulcrum and holds this orientation as the rotating drill proceeds forward. Such a technique can achieve a twelve foot radius of curvature in an existing oil or gas well bore for establishing lateral drain holes essentially horizontal to the otherwise vertical well bore.

Abduction-preventing collar

Abstract: The collar consists of two legs pivoted to each other at one end by a hinge member and releasably locked to each other at the other end by a key operated lock The legs are made of shear-resistant material A radio signal generating and transmitting device and autonomous power supply are housed within the collar A trigger switch is closed to activate the device upon opening of a flap by the abducted collar wearer, and circuitry including a silicon controlled rectifier, causes activation of the transmitter and characterized by the impossibility of deactivation thereof, short of complete discharge of the power supply, as long as the lock locks the legs of the collar around the wrist, neck or ankle of the wearer

Engine inspection system

Abstract: An inspection system in which a fiber optic borescope has an elongated flexible body extending between a control head at a proximal end and an objective assembly at a distal end. The distal end is slidably inserted through a tubular elongated flexible guide member which has an operating head at a near end and a distal collar at a remote end capable of deflecting in four discrete directions. The objective assembly of the borescope is capable of deflecting in two discrete directions. A telescoping rigid support member connects the control head to the operating head and slidably receives the flexible body of the borescope. When the support member is retracted, the control head is proximate to the operating head and the objective assembly extends far beyond the distal collar. When the support member is extended, the control head is distant from the operating head and the objective assembly lies proximate to the distal collar. Cables for operating the distal collar extend between the near end and the remote end and each cable is operatively connected to the distal collar at one end and at the other end to an actuating element on the operating head for manual operation of the distal collar. A coil spring coaxial with the guide member extends between the operating head and the distal collar and firmly holds the operating cables against an inner surface of the guide member.

Variable preload shaft bearing for turbocharger

Abstract: A rotating shaft of a turbocharger is supported by two rolling bearings enclosed in a bearing housing. Two collar members are interposed between the housing and bearings for supporting the bearings in the housing. A U-shaped preloading member is interposed between the two collar members in such a manner that the U-shaped member forms an oil chamber therein. The U-shaped member receives a pressure of a lubricating oil supplied to the oil chamber from an engine, and expands to puch the rolling bearings through the collar members with a greater force when the engine speed is high, and therefore, the oil pressure is high.

Small incision intraocular lens with adjustable refractive power

Abstract: An intraocular lens which is compressible to fit through a small ocular incision into the eye and whose refractive power is adjustable once the inserted lens has been reformed and remedially positioned in the eye. The lens includes a deformable soft optic, a translucent collar encircling the soft optic and attached to it at fixed spaced points, and haptics attached to the collar for remedially positioning the soft optic in the eye. The collar has a separation or break to define two collar arms. When the collar is compressed the arms slide relative to one another to narrow the collar, and the compressed lens can then be inserted in the eye. Once in the eye the collar is released and the arms reformed together to form a rigid circle supporting the soft optic. The soft optic is formed by a transparent bag having a thickened perimeter and filled with a transparent fluid. When the lens is in place in the eye, a fine needle can be inserted into the eye and into the bag perimeter. The amount of fluid in the bag is altered through the needle and the refractive power of the soft optic thereby adjusted as needed.

Control of drilling courses in the drilling of bore holes

Abstract: Drilling apparatus comprises a drill collar (10), a drill bit (12), two spaced stabilisers (16, 18), which act to locate the drill collar (10) within a bore hole (14) being drilled, and a control stabiliser (20) including activating means which do not rotate with the collar for applying a controlled lateral force or displacement to the drill collar in order to deflect the latter between the spaced stabilisers. Sensing means sense the actual drilling course and the latter is compared with a predetermined required drilling course stored in information storage means, the resulting error signal being used to govern operation of the control stabiliser (20).

Pipe flange fire-proofing kit and process

Abstract: A pipe flange fire-proofing kit and process for forming a cast-in fire-stop coupling from normal pipe (22) includes a flange member (10) which is separate from the normal pipe, annularly-shaped top and bottom spacer collars (12 and 14), and an annularly-shaped fire barrier collar (16) Each of these members is slid onto a pipe stub (24) cut from a normal pipe with the top spacer collar being at a top end thereof, the bottom spacer collar being at a bottom end thereof, the fire-barrier collar of intumescent material being immediately adjacent the bottom spacer collar, and the flange member being between the fire barrier collar and the top spacer collar The flange member is adhered to the pipe stub by an adhesive The stub is attached to a concrete form wall (44,54) onto which concrete (42,52) to form a barrier is poured, with its bottom end and the bottom spacer being immediately adjacent the form wall so that upon curing of the concrete the top and bottom spacer collars can be removed so that female couplings can be attached to top and bottom ends of the pipe stub with the fire-barrier collar being open to air from the bottom side of the barrier The pipe stub is attached to the form walls either by attaching members (50) extending from the flange member to the form wall or by a compression column extending from the form wall through the pipe stub to the top end of the pipe stub

External male catheter and applicator collar therefor

The catheter includes a cylindrical section rolled to form a torus that is supported by the collar prior to catheter application, a tapered neck section that extends through the open-ended collar, and an inner sleeve portion that is held in a stretched condition by the collar to help insure placement of the sleeve in sealing engagement with the glans of a patient's penis during the initial stage of catheter application.

Field Performance of a Protective Collar against Damage by Hylobius abietis

Abstract: The effectiveness of a plastic collar designed to protect planted seedlings against damage caused by Hylobius abietis (L.) (Col., Curculionidae) was evaluated at 63 planting sites in southern Sweden during 1979 and 1980. Nearly 10 000 collar‐protected pine and spruce plants and 10 000 controls were carefully examined for Hylobius‐damage and other injuries. In addition, the impact of some microsite factors on weevil damage and collar performance was evaluated, and the height growth was measured. The protective effect of the collar for two seasons after planting was comparable to that of insecticides and was best at sites with sparse vegetation and high weevil pressure. Proper application of the collar was crucial for good control. Collars were not observed to affect plant growth. Soil scarification reduced mortality in both collared plants and controls.

Sports shoe with retractable studs

Abstract: The studs (3) of the shoe are retractable against the action of at least one elastic member (6) calibrated in order to yield to the pressure of the foot on a hard surface and to resist the reaction of the "green". Protuberances are formed projecting under the outsole (1) as far as the level reached by the studs (3) in the retracted position. Each retractable stud (3) comprises a tapped base (8) mounted through the outsole (1), fixed to the latter and delimiting a housing (21) via which at least one elastic element (26) is accessible, the tapped base interacting with a threaded plug (13) having a screwing collar (14) forming a guide (16) in translation for the actual stud (18) which is equipped with a projecting foot (20) located in the housing.

Telescoping pole crank assembly

Abstract: A telescoping pole crank assembly having a tubular pole crank which movably mounts an extension pole for setting the overall length of the pole crank assembly. The extension pole is held in its adjusted position by a locking collar structure including a collar collet fixed to the pole crank and an outside collar rotatably mounted thereon for controlling the engagement of clamping fingers on the collar collet with the extension pole. The extension pole is rotationally interlocked with the pole crank by a series of elongated ribs formed on the extension pole which interfit with slots between clamping fingers of the collar collet. The components are held in assembled relation by rivets which interconnect the collar collet to the pole crank and with the rivets being held in position by the outside collar which is rotatably threaded on the collar collet and a coacting structure on the outside collar and the collar collet limit the separating movement of one with respect to the other after initial assembly.

Liquid container holder

Abstract: A holder for beverage containers which will tightly grip the container when positioned therewith but which is readily releasable to allow for easy removal of the container. The holder comprises a cup-like body for holding the beverage container, a rotatable locking ring and a deformable elastomeric clamping sleeve. The arrangement of the clamping sleeve and the locking collar is such that upon rotation of the locking collar in one direction the collar applies a compressing force against the clamping sleeve which causes a portion of the sleeve to deform radially inwards and to tightly grip against the container so as to frictionally retain the container therewith. Rotation of the locking collar in the other direction releases the compressive force thereby allowing release of the container.

Collapsible artificial Christmas tree

Abstract: An artificial Christmas tree is constructed in a manner to be transformable between a compact storage state and an erected state. The tree has an elongated trunk and a series of branch assemblies spaced upon its trunk. An upper collar is slidably disposed upon the trunk in association with each branch assembly. When the upper collar is moved downwardly, lever arms pivotably attached to the collar causes branch elements to move away from the trunk and assume a tree-like upwardly angled disposition.

Use of the Philadelphia collar as an alternative to the halo vest in patients with C-2, C-3 fractures.

Abstract: We analyzed retrospectively 27 individuals with C-2, C-3 fractures, 8 of whom were treated with a Philadelphia collar rather than the more commonly used halo vest. Successful fusion without neurological deficit occurred in all cases whether treatment was by Philadelphia collar (n = 8), halo apparatus (n = 16), or prolonged bed rest (n = 3). There was an increase in subluxation in 3 patients in both the Philadelphia collar group and the halo apparatus group. However, 1 of the 3 in the collar group was uncooperative and discarded his collar during treatment. If he is excluded, the subluxation rate in the Philadelphia collar group is 27%; the rate in the halo group is 19%. The Philadelphia collar seems to be an acceptable means of stabilizing the neck in C-2, C-3 fractures, but one must consider the degree of cervical movement in the collar (as detected by dynamic x-ray films), patient reliability, and patient age. The presence of subluxation did not preclude successful fusion in either the Philadelphia collar or the halo vest groups.

Combination collar and muzzle humane training aid

Abstract: A combination collar and muzzle is used as a humane method of restraining, controlling, and achieving obedient behavior of animals, dogs in particular. A collar member or loop encircles the neck immediately behind the ears, and a second muzzle loop encircles the upper and lower jaws of the animal to form a type of a figure eight combination collar and muzzle. The two loops are coupled together with a ring behind the jaw. The muzzle loop is adjustable in length. An optional adjustable keeper strap is connected between the collar loop and the muzzle loop to retain the muzzle loop from being pawed off.

BLS White-Collar Pay Survey Now Covers Small Firms

Abstract: Clericai workers and recent hires in professional and administrative positions typically are paid 10 to 20 percent more in large firms employing 2,500 workers or more than in small firms employing 50 to 999 workers. In contrast, the pay advantage for fully experienced professionals in these large firms is usually under 5 percent. (See table 1 .) The national survey of professional administrative, technical, and clerical pay (PATc survey) in 1986 increased its coverage of firms with as few as 50 workers. As a result of the expansion, 156,000 establishments employing 33.5 million workers were covered in 1986 (previously, the survey covered 47,000 establishments employing 23.3 million workers) . Establishments in Alaska and Hawaii are excluded . The survey is conducted by the Bureau of Labor Statistics, but survey occupations and coverage, such as establishment size and the private industries to be included, are determined by the President's Pay Agent (the Secretary of Labor and the Directors of the Office of Management and Budget and the Office of Personnel Management) .' In addition to the size of a firm's work force, skill and experience also influence white-collar pay, as can be readily seen from the survey results. (See table 2.) Engineers, the survey's most numerous occupational group, illustrate the effect of rising skill levels on pay: recent engineering graduates (level I) averaged $27,866 annually in March 1986, while engineers responsible for highly complex engineering programs (level VIII) averaged $79,021 .2 In contrast, skill levels can act as a source of pay uniformity for the same level of work among different occupations . The following tabulation shows a relatively narrow (9 percent) spread separated the highest paid and lowest paid of six equivalent work levels in the survey :

Method of attaching a tube to a fin

Abstract: This specification teaches a method of attaching a fluid conducting metal tube (12) a heat dissipating metal fin (14) that includes the following steps. A metal tube (12) is formed having a generally elliptical cross-section having first similarly curved surfaces (22--22) at opposite ends of a major axis thereof and second similarly curved surfaces (24--24) at opposite ends of a minor axis thereof. A heat dissipating metal fin (14) is formed. An elliptically shaped collar (20) is formed on the fin, this collar providing an opening through the fin and being at least about 11/2 times the thickness of the metal forming the fin. The tube is fitted inside the opening of the fin so that areas of these two elements are juxtaposed. The tube is expanded along the major axis so as to bring the first similarly curved surfaces at opposite ends thereof into contact with portions of the collar in juxtaposition therewith. Expansion of the tube is continued along the major axis and initiated along the tube from opposite ends of the major axis toward the surfaces which were defined at opposite ends of the minor axis of the tube. In this manner, any juxtaposed area of the tube and the collar are subjected to an expansion process in which the tube is moved towards the collar, the two elements are brought into contact with one another, and then the two elements are expanded together. The expansion process is progressively terminated between the tube and collar from the major axis of the tube toward the minor axis thereof. The termination occurs in such juxtaposed areas as those areas reach a condition in which the tube is being deformed plastically but the collar is still being deformed elastically. In such a manner, excellent mechanical and thermal contact is made between the tube and the collar of the fin whereby excellent heat transfer may be carried out therebetween.

Vacuum cleaner bag mount and method for mounting a dust bag thereon

Abstract: A canister vacuum cleaner includes a dust bag mount for mounting a dust bag with a collar onto the vacuum cleaner. The bag mount includes a mounting plate with a circular aperture. The dust bag collar includes an aperture that, upon installation of the collar, is aligned with the aperture in the mounting plate. Raised structure surrounds the aperture in the mounting plate and extends into the aperture in the collar upon installation providing a seal between the mounting plate and collar. The raised structure includes ramps and inclined surfaces to bend and lift the dust bag collar over the raised structure during its installation and removal. This structure also serves to index and retain the collar once it is installed and to seal the space between the installed dust bag collar and the mounting plate. A pair of channels are provided at the sides of the mounting plate for holding and guiding the edges of the dust bag collar during its installation and removal. A ramp is provided in each channel which acts to bias the dust bag collar against the mounting plate upon the installation of the dust bag. The channels are also sloped or angled relative to the mounting plate to reduce the stress imparted to the dust bag collar during its installation and removal and to move the dust bag collar against the mounting plate once the collar is installed. The dust bag collar includes a gripping tab and an aperture in the gripping tab to facilitate the removal of the dust bag collar from the bag mount.

Self-righting highway marker support and method for installing same

Abstract: A self-righting roadway marker support for a flexible boundary or roadway marker has a hollow anchor sleeve sunk into a supporting surface, a mounting collar secured to said anchor sleeve, a pivot strut extending through and upward from the collar, a compressible coil spring to resiliently urge the strut into contact with the collar, and a spring stop which selectively limits the extent to which the coil spring may be compressed. An oblong, radiused or chamfered aperture formed in the collar cooperates with a spring-mounting eyebolt to prevent the strut from rotating when deflected. A tool is also disclosed for installing the marker support. The force required to deflect the support assembly is set to be less than the force that would destroy or permanently set or deform the boundary marker.

Thread form and fastener system using the form

Abstract: A modified buttress thread has a root diameter equal to substantially √0.7 of the core diameter with a pitch substantially equal to 1/6 of the core diameter. The thread root extends parallel to the axis of the fastener as a surface and transitions into the thread form at radii at both the load-bearing and trailing flank of the thread. The thread at its maximum diameter has a flat equal to about 0.16 of the pitch. In the fastener system the axial length along a thread form of the collar at radial locations corresponding to the locations on a mating pin are inversely proportional to the strength of the materials of the collar and the pin, for example, when the collar is aluminum and the pin is titanium the lengths are in the ratio of 60:40.

Collar for retaining camera bracket mount in place

Abstract: A camera support collar or ring for releasable attachment to the upright post of a photographic camera assembly support which includes a clamping means with an adjustable collar made up of first and second semi-circular segments with a threaded screw means secured to one of the segments for releasably holding the segments in post-gripping disposition at a predetermined elevation on the camera receiving post. A radially extending housing extends outwardly of one of the semi-circular segments and releasably retains a camera position locking pin therein, with the locking pin being arranged for axial movement to an elevation above the upper surface of the collar for engagement with a camera assembly mounted upon the upright post above the upper surface of the adjustable collar, thereby permitting the user to reposition the camera assembly following movement from a prescribed or desired position.

High speed boat lifting structures

Abstract: A thrust collar is disclosed for mounting around the upper portion of the propeller of an inboard/outboard engine. Each thrust collar supports a horizontal hydrofoil wing extending laterally from the collar. A second, similar wing can be provided on an opposing side of the collar. Where the collar is used in pairs on paired engines on a catamaran hull, a single hydrofoil wing can be supported between the thrust collars. The thrust collar is preferably used in conjunction with hull lifting structures. One hull mounted hydrofoil structure is supported at the lower end of the strut extending and includes a generally curvilinear gull-wing shaped lower surface. For V-type hulls, a pair of elongataed mechanical lifting structures, symmetrically positioned on either side of the keel substantially in the vicinity of the keel are attached to the hull so as to extend generally traversedly to the sloping side surfaces of the hull intersecting at the keel. These lifting structures have a length many times greater than their maximum transverse dimension and preferably extend from a position approximately a midship beneath the hull to the stern of the hull. Retractable hydrofoil assemblies are described for drawing a strut supporting a hydrofoil wing into a boat or rotating the strut upward into a tunnel beneath the boat in the case of a catamaran hull.

Clutch and release bearing assembly

Abstract: The assembly includes a first sleeve connected to a releasing mechanism of a clutch and having a screw threaded surface. A second sleeve is movable relative to the first sleeve and is operatively connectable to a release member. A collar is in threaded engagement with the first sleeve and clutch release forces are transmitted through the collar from the second sleeve to the first sleeve. The collar is prevented from rotating relative to the first sleeve during clutch release. An abutment is provided on the clutch for releasing the collar when the second sleeve reaches a predetermined position to allow the collar to rotate and allow the first sleeve to move axially relative to the second sleeve. A spring for urging the second sleeve towards the clutch acts between the second sleeve and part of the abutment on the clutch. A locking ring may be provided for locking the collar to the second sleeve during clutch release.
