Input impedance of a monopole antenna at the center of a finite ground plane

Abstract: A technique for computing the input impedance of a monopole on a finite ground plane is provided. The case of an infinite ground plane is first examined, and then the concept of using a magnetic edge current as an equivalent source of diffraction on the limited size ground plane is introduced. The technique used is serf-consistent in that the circular ground plane considered is the limit of a polygonal ground plane as the number of sides tends to infinity. Good agreement has been demonstrated when the nearest edge of the ground plane is at least 0.3 wavelength from the base of the monopole.

Stereoscopic real image scanning reproduction method and apparatus

Abstract: My invention relates to photographing scenes with standard motion picture photographic equipment where multiple views of a subject are photographed while the subject rests on a moving turntable and the stationary camera has its optical axis pointed at the turntable rotation axis or where the subject is stationary and the camera effectively moves in an arc about an axis located between the camera and scene. The surface of the processed film (or other appropriate media) is arrayed in a vertical plane and constrained to move horizontally around a portion of a circle. Film images are scanned by a light source and radially projected in a direction away from a vertical rotation axis. Concentric with the vertical axis are the semi-specular screen of radius R and the scanning projector circle of radius close to R/3. The screen reflects projected light in a horizontal plane and scatters projected light in a vertical plane. The film is rapidly scanned by the projector and the images are projected sequentially while sweeping horizontally over the screen when the projector is between the vertical axis and the screen. At any instant, all projected rays reflected from the screen return to a vertical aerial exit slit along the projector's optical axis on the opposite side of the vertical axis with respect to the scan projector and on a scan circle radius about equal to R. The exit slit scan cycle repeats at short time intervals so as to avoid flicker.

Swingable hanger support member

Abstract: A swingable hanger support member comprises a laterally extending longitudinal member provided at one end thereof with a downturned portion adapted to be received in an aperture for pivotal movement thereabout. The other end of the longitudinal member is provided with a formation which defines with the longitudinal member a pair of V-shaped apertures which are adapted to wedgingly engage spaced portions of a hook of a conventional hanger so as to releasably support the hanger in a vertical plane substantially coplanar with the vertical plane defined by the longitudinal member and the downturned portion.

Apparatus for the spark deposition of metals

Abstract: There is disclosed an apparatus for the electric spark deposition of metals. The apparatus comprises a logic block, the input of which is connected to the output of a following system, a motor for horizontal motion in the x-direction and a motor for horizontal motion in the y-direction, such motors being connected by their inputs to a command unit and by their outputs to the movable table of the deposition apparatus; the motor for horizontal motion in the x-direction, the motor for horizontal motion in the y-direction and the motor for vertical motion are connected, respectively, to one of the outputs of the logic block. The advantages of the apparatus of the present invention are that it is provided with an electronic control of the motors for the horizontal and vertical motions of the depositing electrode-anode, which permits the total automation of the process of electric spark deposition onto workpieces, as well as the regulation of the inclination of the depositing head with respect to the vertical plane. Moreover, this device permits the maintenance of a working gap between the forming surface of the depositing electrode-anode and the deposited material; this makes possible deposition in a horizontal plane along coordinate axes ±x and ±y and depositing onto internal and inclined surfaces.

Means are provided grounding the outer conductor of the transmission line to the ground plane, the inner conductor top-connecting the monopoles.

Preliminary results of a field experiment to characterize wind flow through a vertical plane

Abstract: Preliminary results are presented of a field experiment to study the turbulent structure in the wind flow through a simulated disc of rotation of a large, horizontal-axis wind turbine blade. The wind flow impinging on the hypothetical turbine blade was simulated by a nine-element circular array of three component anemometers in a single vertical plane. The wind data were analyzed as: a single point, hub height measurement (at the center of the array); an arithmetic average of all sensors; and a synthesis of the data records assumed to represent measurement locations on a hypothetical, rotating turbine blade. The effects of areal averaging were examined using the arithmetic mean over the array. Similarly, the effects of averaging over the blade pair were examined by arithmetically averaging opposing data points representing the air flow past the rotating blade.

Wave loads on horizontal cylinders

Abstract: The problem of predicting wave induced loads on cylinders is an enormously complex one. It is clear from the scatter present in most experimental determinations of force coefficients that there are many individual factors which influence the mechanisms of flow induced loading. Among these are some, for instance Reynolds number, separation and periodic vortex shedding, which are inter-related and whose influences cannot be studied in isolation. Others, such as shear flow, irregular waves and free surface effects, can at least be eliminated in the laboratory, in order to approach an understanding of the more fundamental characteristics of the flow. A vertical cylinder in uniform waves experiences an incident flow field which can be described in terms of rotating velocity and acceleration vectors, always in the same vertical plane, containing also the cylinder axis, whose magnitudes are functions of time and of position along the length of the cylinder. Some of the essential features of this flow can be studied under two-dimensional oscillatory conditions, in which either the cylinder or the fluid is oscillated relative to the other along a straight line (planar oscillatory flow). The incident velocity and acceleration vectors are then always concurrent, normal to the cylinder axis, and oscillating in magnitude with time.

Turret type metal working machine

Abstract: A turret type machine tool indexable to selected positions with a plurality of identical tools supported in each of the indexed positions to work on a like number of rotatable workpieces. The tool carrying turret is indexable about an axis located in the same plane as the axes of rotation of the workpieces. The turret is movable in a vertical plane between working and nonworking positions on bearings which are symmetrically disposed relative to the plane so that tool loads at the workpieces are distributed to the remainder of the machine symmetrically relative to the same common plane.

The Steady Wave Potential of a Unit Source, at the Centerplane

Abstract: The paper is concerned with the linearized wave disturbance trailing downstream from a unit source in steady rectilinear motion at or below the free surface of a quiescent sea, at the "centerplane," that is, at the vertical plane of symmetry containing the source and parallel to its direction of motion.

Method and apparatus for making wide exit pupil viewable holograms

Abstract: In a method and apparatus for recording a holographic image on a photosensitive medium or film which is capable of being viewed from a wide vertical viewing angle when illuminated by incoherent light, a source of coherent light (10) is divided by splitter (14) into a reference beam (16) and an image or object beam (18). The image beam is directed toward the object, either a transparency (20) or a three-dimensional object (20a), and the image thereof is focused in the vertical plane by means of an anamorphic lens (30) onto a vertical dispersion element (35) and the image thereon is gathered and focused in the vertical plane by means of anamorphic lenses (36 and 38) onto the film (40). In the horizontal plane, the image is focused by an anamorphic lens (42) onto a horizontal exit pupil forming means which may include horizontal dispersion element (45) and the light therefrom is directed onto the film (40). The reference beam (16) is directed onto the film from either the back or the front at a predetermined angle in a vertical plane. The holographic image may be recorded in full color by simultaneously or sequentially generating coherent light in the primary colors and directing the reference beam of each color onto the film at a unique predetermined angle in a vertical plane. The image is reconstructed by directing incoherent light onto the film at the same angles in the vertical plane as the reference beam.

Formation of radius elbows and O.G. sets

Abstract: A machine for automatically assembling radius elbows and/or O.G. sets, and the method of utilization of the machine. Four edge deformation effecting components, such as Pittsburg rollers or air hammers, are provided for interlocking edge configurations of ducts to be formed, the edge deformation components defining the corners of a vertical quadrate opening. Two of the components are mounted at the same vertical height above a fabrication table for movement relative to each other in a horizontal direction perpendicular to the horizontal direction of feed of duct pieces through the quadrate opening defined by the edge deforming components. The other two edge deformation components are located at substantially the same level as the rollers of the fabrication table, rollers of the fabrication table being disposed on either side of the vertical plane containing the four edge deformation components. The mounts for the edge deformation components are rotatable about vertical axes to accommodate O.G. sets, when being formed, and the maximum horizontal spacing between the components of the respective pairs of edge deformation components is less than the length of the rollers of the fabrication table.

Centrifuge for blood sepn. - has a rotor with sample tubes holder, the angle of inclination from the vertical being limited to reduce rotor size and speed up time

Abstract: Sepn. centrifuge is used for biological specimens, such as blood, esp. to recover plasma after the plasma phoresis process. The centrifuge has a rotor with holders attached to it which can swing about a pivot on horizontal axis from the vertical rotor axis. These normally hang in the vertical plane but swing out as velocity builds up. The angle of tilt the vertical is limited to 30-60, pref. 45 degrees. There are two such holders, one on either side of the rotor. The design allows a smaller design of housing and bowl a shorter run up time, reduced vibrational moment on the machine, low, total wt. for the machine which is thus more easily portable and can be used in mobile blood donor centres, even on aircraft.

Measurement of relative movement between two phases

Abstract: For measuring the speed of movement of one phase in another, and particularly the rate of sedimentation of corpuscles in blood plasma, a container is filled with a blood sample, a light beam is directed through the container and an image of a vertical plane in the container traversed by the beam is formed in a measuring plane, the light intensity at two vertically spaced regions of the measuring plane is measured, the container is moved until a certain light intensity relationship exists between the two regions, indicating that the image of the boundary of the one phase in the other phase is located between the regions, and after a selected time interval the container is raised until the same light intensity relationship is established between the two regions and the distance through which the container has been raised is indicated.

Laser scan converter

Abstract: A laser scan converter is disclosed which converts the scan of a laser li beam in one plane--say, a horizontal plane--into a scan thereof in another plane--say, a vertical plane. The invention comprises a rotating multi-faceted mirror which, as it rotates, intercepts in a first plane a laser light beam that optionally has passed through a semi-mirror and reflectively scans it back to the reflective surface of said semi-mirror which re-reflects and redirects it to a full mirror which, in turn, re-re-reflects and re-redirects it to a predetermined surface of a utilization apparatus, the surface of which is located in a second plane that is different from the aforesaid first plane--say, one that is perpendicular thereto.

Wind operated power generator - has vertical shaft with several rings of pivoted and counterbalanced blades rotating in horizontal planes

Abstract: The turbine has a vertical shaft on which several rings of blades are assembled one above the other. Each ring contains six blades equally spaced round the ring. Each blade is carried at the end of an arm projecting radially from the shaft. The blade can swing about the arm and is counterbalanced by a weight which swings about the radial arm in a vertical plane. The mechanism brings the blade down to catch the force of the wind and swings it to a horizontal position on the return part of its motion so that it offers no resistance to the wind. The vertical assembly of several rings enables the full power of the wind to be caught.

Reversible plough with swinging support wheel - has follower shaft connected between swing shaft and wheel carrier with pivot shaft acting about setting shaft in frame

Abstract: The reversible plough has a swinging support wheel which can be moved between a transport- and use positions. The support wheel carrier can be pivoted about a swing axis which is horizontal in the use position and transverse to the working direction. During ploughing, it automatically changes from one working position into the other about this axis. The pivot shaft (5) can be pivoted about a setting shaft in the plough frame (10). A follower shaft (3) is connected between the swing shaft (5) and support wheel carrier (2) or between setting shaft (8) and swing shaft (5). This follower shaft (3) lies in the vertical plane which passes through the support point of the pivot support wheel on the ground.

Hanger for track-type suspended railway

Abstract: The suspension cable of a suspended railway lies in a vertical plane above the elongated track thereof. Hangers interconnecting the suspension cable and the track each have an upper part connected to the suspension cable, a lower part connected to the track, and an intermediate part pivoted on the upper and lower parts about respective horizontal upper and lower pivot axes. The lower pivot axis is perpendicular to the plane of the suspension cable and to the direction of elongation of the track, and is relatively close to the upper surface of the track. The upper pivot axis is generally parallel to the track and lies in the plane of the suspension cable, but is spaced from the upper surface of the track by a distance equal at least to the width of the track in a direction perpendicular to the plane thereof. Between these two pivot axes the intermediate part is completely rigid.

The microscale sensing array

Abstract: A moored self-recording instrument designed to measure the fine scale temperature and velocity vector variability of the ocean in a vertical plane containing the mean velocity vector is described. (Since the conception, design, and naming of the microscale sensing array (MSA) the scale designation of phenomenon with wave lengths in the range (0) 1 to (0) 10 m has been changed from ‘mieroscale’ to ‘fine scale.’) The structure holds 16 water velocity sensors (propellors) and 14 water temperature sensors (thermistors). These sensors are mounted along two vertical masts, each 8 m long, separated horizontally by a 20-m spar. The whole structure is rigid, buoyed by two aluminum spheres, each 1 m in diameter, providing a net buoyancy for the instrument of about 386 kg. Contained within the spheres are an electronic data acquisition system, a magnetic tape recorder, primary batteries, a compass, and accelerometers to measure roll and pitch attitude. A separate cylindrical housing contains a pressure transducer and preamplifiers to sense depth. Provision is made to measure MSA translational motion by means of an acoustic transceiver and remote transponders. Instrument life is primarily dependent upon tape storage (53 million bits) and data sampling rate, which is easily preset to various continuous or burst modes. Maximum allowable operating depth is presently 900 m. The MSA has been deployed four times in the main thermocline southeast of Bermuda and once in the New England Continental Shelf bottom boundary layer.

Wind driven impeller with vertical axis - has vanes swivelling on horizontal axes to eliminate resistance during movement against wind

Abstract: The wind-driven impeller rotates about a vertical axis and has at least two semi-circular vanes each of which is rotatable about a horizontal axis. Each vane is held in a vertical plane as long as it moves with the wind and turns to be in a horizontal plane when, after 180 deg. rotation, it moves against the wind direction. The rotation of the vane on its horizontal axis is derived from the impeller rotation via bevel gearing or friction wheels, spring and coupling arranged to produce instant swivelling of the vanes at each 180 deg. impeller turns. The movements of swivel motion automatically adjusted depending on the direction of the wind.

Method of manufacturing flexible cable by nonncage type winding and twisting process

Abstract: Improvements in apparatus for the manufacture of a cable by laying or assemblying pre-twisted outer strands around a pre-twisted core. For smooth transmission of the pre-twist through the core length from a pay-out reel to a laying die, a series of interspaced pairs of opposed guide rollers are disposed along the path of the core to engage the same therebetween. Further, for smooth transmission of the pre-twists through the lengths of the outer strands from respective pay-out reels to the laying die, a series of interspaced tapered guide rollers are disposed along a curve in the path of each outer strand. At least some of the tapered guide rollers are set an an angle to the axial direction of the outer strand being fed thereover and, preferably, further to the direction normal to the vertical plane containing the curve in the outer strand path.

Wind-driven vertical axis rotor - has linkage and stop roller between adjacent blades to noiselessly feather blades rotating against wind

Abstract: The wind-driven rotor rotates about a vertical axis (1) and comprises a number of blades (2, 3) arranged to be in a vertical plane when moving with the wind and to rotate about a horizontal axis (14) to be in a horizontal plane when moving against the wind. Adjacent blades (2, 3) are linked (18, 16; 19, 17) via a coupling wheel (15) whilst each blade (2) is provided with a lever (8) carrying a roller (4) which runs in a track (5) on the adjacent blade (3). The end of this track acts as a stop to prevent the blade from turning beyond the horizontal plane. This roller arrangement ensures that the change of position from vertical to horizontal takes place without generating noise.

Ski brake with brake skids mounted on beam - rotating in horizontal and then in vertical plane to turn blades through ninety degrees

Abstract: The Ski brakes consists of two skids (11, 12) with serrated edges, rigidly attached to opposite ends of a beam (7). The beam (7) is mounted by a horizontal hinge pin (9) to a bracket (4) which is in turn, fixed with a vertical hinge pin (2) to the ski. A catch (19) holds the beam in longitudinal alignment with the ski. When the skier's foot leaves the ski the catch (19) is released and the tension spring (14) rotates the beam through 90 deg. in the horizontal plane. The blades (11, 12) dig into the snow and are then rotated through 90 deg. in the vertical plane so that a high braking force is exerted on the ski.

Propeller tunnel for ships under arctic conditions - has funnel shaped inlet extension piece tapering in water flow direction

Abstract: The propeller tunnel is particularly for seagoing ships and which have to travel through ice, the propeller being accommodated inside a flow ring. At the inlet end (4) of the ring (2) is a funnel-shaped extension piece (5), tapering in the flow direction. This extends to both sides of a vertical plane (6) through the propeller shaft. The piece can be rounded on the inlet side at right angles to this plane, and it can be inclined to this plane at from 15-50 deg., preferably 15-35 deg. This angle (8) of inclination can be >= that between the outside of the hull and the same plane.
