Audiovisual annunciator with priority ranking for each condition

Abstract: An audiovisual annunciator for warning a system operator of the occurrence of various monitored conditions within the system. A signal generated in response to the occurrence of a monitored condition energizes an associated warning lamp to visibly indicate that the condition has occurred. An audio signal is simultaneously generated and acoustically transmitted to the system operator. A logic circuit assigns a priority ranking to each condition, such that, when several conditions occur simultaneously, an audio signal is generated for only the highest priority condition. If the operator acknowledges the highest priority annunciated condition, an audio signal is transmitted for the next highest priority occurring condition. The operator may recall a silenced warning so long as the condition continues to exist. A switch permits the operator to test the warning lamps, the priority circuitry, and the audio circuitry.

Inflatable vehicle confinement

Abstract: A vehicle safety apparatus includes an inflatable confinement which is inflated by the flow of fluid from a fluid reservoir to the confinement. The confinement has a generally cylindrical shape and is constructed to receive and locate the fluid reservoir therein. The confinement is compartmentalized in certain embodiments. The compartmentalized confinement is operable to restrain movement of a plurality of vehicle passengers during a collision. The compartmentalized construction provides a restraint for each passenger and operates to control each passenger substantially independently of any other passengers during a collision. In another embodiment of the present invention, a plurality of compartmentalized confinements are utilized to control movement of the occupant of the vehicle during a collision.

Fluid coupling device

Abstract: A fluid coupling device includes relatively rotatable input and output members. The output member defines a working chamber in which a portion of the input member rotates, and a fluid in the working chamber transmits torque between the input and output members. A fluid reservoir is provided adjacent to the working chamber, and a flow of fluid is effected between the reservoir and the working chamber by operation of a flow control means. The flow control means includes a valve shaft located in an opening in the output member and an O-ring seal member provides a seal between the shaft and the output member. The seal has an external groove which abuts the surfaces of the output member surrounding the opening in which the shaft is disposed. The valve shaft is axially positioned in the opening by an annular groove formed in the valve shaft which receives an internal portion of the O-ring shaped seal member.

Vehicle safety apparatus for restraining occupant

Abstract: An improved safety apparatus for protecting an occupant of a vehicle during an accident includes a confinement. Upon the occurrence of an accident, the confinement is inflated to an expanded condition to restrain movement of the occupant by absorbing kinetic energy. To minimize rebound of the occupant from the confinement, an exhaust or blowout assembly is provided for dissipating the absorbed kinetic energy by enabling fluid to be discharged from the confinement. The exhaust or blowout assembly includes a patch which is ruptured or blown out of a blocking relationship with an aperture or opening in the confinement by fluid pressure. To preserve the integrity of the exhaust assembly until a predetermined fluid pressure is present within the confinement, the patch is mounted in such a manner as to enable relative movement to occur between the patch and the confinement.

The fixture has an elongated body with operating interconnected extendable arms having abutment means on the ends thereof for engaging the sides of the drawer to align the center line of the fixture at the midpoint between the drawer sides. Guide apertures are formed in the fixture equally spaced on opposite sides of the center line for locating hole locations equally spaced from the midpoint of the drawer. The guide apertures are formed in movably mounted interconnected blocks that move uniformly in opposite directions to adjust the spacing between the guide apertures to accommodate various size door pulls.

Inflatable safety apparatus

Abstract: An improved safety apparatus for protecting the driver of a vehicle includes a confinement mounted on the steering wheel and having a circular cone portion which engages the torso of the driver when the confinement is expanded to thereby restrain movement of the driver during a collision. The confinement is inflated from a collapsed condition to an expanded condition in such a manner as to engage the rim of the steering wheel with the confinement before engaging the torso of the driver with the conical portion of the confinement. After forward movement of the torso of the driver has been retarded by engagement with the confinement, the head of the driver engages the conical portion of the confinement.

Control for a hydrostatic transmission

Abstract: 1,219,548. Hydrostatic transmission control. EATON YALE & TOWNE Inc. 8 April, 1969 [8 April, 1968], No. 17944/69. Heading F2D. In a control system for a vehicle hydrostatic transmission 11 wherein a manual control element is connected by a linkage to a lever 41 controlling the ratio of the hydrostatic transmission 11, the linkage contains a lost-motion connection which permits a spring assembly 120 to move the lever 41 to its neutral position when the manual control element is within a predetermined distance of its neutral position. A manual control lever 12 is connected through a linkage 30 ... 34 to a lever 35 fast with a stubshaft 36 and two pedals 13, 14 are also connected to the lever 35 through linkages 70, 80 so that rotation of the lever 12 from its neutral position 20c or depression of the pedal 13 or 14 rotates the lever 35 and stub shaft 36 in one direction or the other. The stub shaft 36 carries a lever 37 connected through a lost-motion spring coupling 40 to the lever 41 so that rotation of the stub-shaft 36 pivots the lever 41 to operate a control valve 43 which supplies pressure fluid to a follow-up servomotor 46 controlling the swash-plate of the hydrostatic transmission 11. The lost-motion in the linkage may be provided by a lost-motion connection between a rod 39 and the lever 41 or may be provided in the lost-motion spring connection 40. The spring assembly 120 is adjustably secured to the tractor by an eccentric mounting (Fig. 9, not shown). Adjustably positioned spring-pressed plungers (60), Figs. 2-4 (not shown), project into the path of the lever 12 to indicate to the driver that a predetermined ratio has been obtained. Additional effort is required to move the lever 12 past the plungers (60). A lost-motion spring coupling 33 in the linkage 30 . . . 34 between the lever 12 and lever 35 permit the latter to be rotated by the pedals 13, 14 without a corresponding movement of the lever 12. The pedals 13, 14 carry lugs 73, 83 engageable with arms 72, 82 fast with a sleeve 74 and shaft 75 carrying arms 78, 85 connected by links 79, 86 to the lever 35. On depression of one of the pedals, e.g. 13, the lug 73 engages the arm 72 and acts through the linkage to rotate the lever 35 anticlockwise. The rotation of the lever 35 acts through the linkage 86, 85, 75 to rotate the arm 82 clockwise. Sufficient clearance between the lugs 73, 83 and the arms 72, 82 is provided to prevent clockwise rotation of the arms 72, 82 effecting movement of the pedals 13, 14.

Press synchronizing apparatus

Abstract: 1,223,201. Automatic speed control. EATON YALE & TOWNE Inc. Jan. 2, 1969 [Jan. 2, 1968], No.362/69. Heading G3R. A slave press B is maintained in synchronism with a master press A. The press B is driven by a motor 21B through a variable coupling 23B whose energization is controlled by a circuit 31B the input to which is the algebraic sum of the signals from a speed reference source 39, from a tachometer 29B whose output varies in amplitude with the speed of the press and from a phase comparator 51B whose output varies in amplitude with the angular displacement between the crank-shaft of the press and the reference standard A. As shown the reference press A is also driven through a coupling 23A controlled to maintain the speed set by the speed reference 39 and drives the rotor 43A of a selsyn 41A. The press B also drives a selsyn 41B, the stators of the two selsyns being coupled. The A.C. supply to selsyn 41A is compared with the output of 41B by a phase discriminator 51B whose output is fed to the control circuit 31B. The speed reference 39 may provide a fixed reference or may vary so that the presses follow a set programme. In a modification, Fig.2 (not shown) the selsyns are replaced by pulse generators feeding digital counters whose outputs are compared and the result converted in a digital to analogue converter to a phase error signal which is fed to the control circuit 31B as described in Specification 1,223, 202.

Method of and apparatus for carbonating, having intersecting streams of gas and liquid

Abstract: A two-stage carbonator for carbonating fluids in a single chamber having a venting system by which the chamber is at least partially vented of pressure to allow entry of fluid from a lowpressure line. The pressurized gas inlet directs the stream of gas tangentially to the liquid outlet through a normally open valve. The gas stream is thus directed into the chamber during discharge and passes adjacent the discharge opening thereby supercharging the exiting fluid, increasing the degree of carbonation.

Computer control of parallel paper mill refiners for controlling the freeness of stock by controlling the stock temperature rise through each refiner

Abstract: Apparatus is disclosed for controlling freeness of stock from parallel refiners by controlling the rise in temperature of stock through each refiner. The DELTA T setpoint for each refiner is adjusted to compensate for: variations in consistency of stock; maximum power rating of the refiner; weighted average freeness of stock from all refiners; and the composite frheness of stock delivered to a paper machine. Error in the desired temperature rise of a given refiner is employed to control its disc or plug operation. An on-line analyzer is employed to monitor composite freeness. Couch or flatbox vacuum is employed as an alternative measure of composite freeness, but only if intentional paper machine changes which would affect vacuum have not been made. Operator control of composite freeness is also permitted. The composite freeness setpoint is adjusted to maintain a desired paper bursting strength. Power checks are made and instructions are automatically given to adjust flow rate to an individual refiner in order to keep it operating within its maximum power limit and to add or delete refiners for optimum efficiency.

Twin countershaft construction with all main gears mounted concentrically on main shaft

Abstract: 1,168,709. Variable-ratio gears. EATON YALE & TOWNE Inc. 14 Aug., 1967 [6 Sept., 1966], No. 37316/67. Heading F2D. A multi-countershaft transmission has means ensuring equal flow of power through each countershaft. An input gear 42 floats radially with respect to an input shaft 41, and meshes gears 47, 62 on countershafts 46, 61. Gears 48-52 fast on countershaft 46 and gears 63-66 fast on countershaft 61 mesh gears 78, 83, 87, 91 which are selectably clutchable to an output shaft 72, and countershaft gears 53, 67 drive an output gear 94 through reversing idlers. The gears 78, 83, 87, 91, 94 are rotatably supported on the output shaft by bushings so as to be held against any appreciable movement with respect to its axis. The clearance between the teeth of each output gear and the countershaft gears associated therewith is made greater than is usual, and sufficiently great to permit the countershaft gears of each unclutched set to respond to the relative positions with respect to each other of the countershaft gears in a clutched gear set without binding against the respective output gears of each unclutched set, so that all the output gears which are unclutched at a given time will be free from binding against any of the countershaft gears regardless of which gear set is clutched at this time. The input gear is mounted on the input shaft by way of a sleeve 146 having short internal and external splines at the opposite axial ends thereof to permit radial movement as described in Specification 1,163,774. Specifications 1,069,113 and 923,267 are also referred to.
