Title: Improvements in automatic reclosing electric circuit interrupters
Inventor: RYAN ANTHONY VAN
IPC: H01H75/04
Filed: 1951-07-02
Abstract: 704,894. Automatic reclosing circuit-breakers. McGRAW ELECTRIC CO. July 2, 1951, No. 15659/51. Class 38(5) The automatic reclosing circuit breaker of Specification 704,893 is modified in that a mechanically driven pumping piston is provided to effect the movement of a "counting" piston independently of the hydraulic delay arrangement of the magnetic plunger of the electromagnetic switch operating means. The pumping piston 66 is connected by a link 74 to a bell crank lever 48, 50 freely pivoted on a shaft and connected by a link 47 to the plunger 15. Thus on each downward switch opening movement of the plunger 15, the piston 66 makes a downward pumping stroke to pump oil through a passageway 69 into a cylinder 70 to move or advance the " counting " piston 71 one step. Each downward movement of the plunger 15 pumps the oil beneath the plunger up into a passage 74 where it raises a slide valve 75 to uncover a port 84 through which the oil escapes freely during the initial rapid opening operation or operations of the circuit breaker. When the desired number of rapid operations has occurred, the piston 71 will have moved sufficiently to cover the port 84 so that subsequent downward switch opening movements of the plunger are delayed by the slow escape of the oil from beneath the plunger through the aperture in the plate 7 through the. plunger moves, the opening 80 in the valve 75 being closed as the valve abuts a plate 82. This opening 80 controls the rate of return of the plunger 15 to determine the delay between successive operations. When the desired number of rapid and slow opening operations have occurred the piston 71 breaks a toggle 62, 60 which collapses to hold the circuit breaker open as in the above Specification. A weighted valve 73 permits the settling of the piston 71 to reset the circuit breaker if a fault is cleared before the sequence of operation of the circuit breaker is ended and also to permit manual resetting after a complete sequence of operation.

Patent GB-1422763-A (GB)
Title: Variable dwell ignition system
IPC: F02P3/045
Filed: 1974-04-10
Abstract: 1422763 Ignition systems MOTOROLA Inc 10 April 1974 [11 May 1973] 15849/74 Heading F1B The Specification decribes a transistorized variable dwell ignition system which converts to a constant dwell ignition system at a predetermined engine speed. Preferably a magnetic pick-up device (not shown) is positioned within the distributer to produce a sequence of trigger pulses which are applied to an input terminal 10. Each input trigger pulse triggers a monostable multivibrator 11 into its astable state to produce an output pulse. This output pulse initiates a cycle of operation of a 70% duty cycle circuit 12 so long as the output pulse from the circuit 11 exists, the time multiplying circuit 16 is prevented from operating by the output of an AND gate 14. When the output of the multi-vibrator 11 terminates, a cycle of operation of the time multiplying circuit 16 is initiated provided the 70% duty cycle circuit 12 is still in its off condition or in the 30% portion of its cycle. If this condition exists the time multiplying circuit 16 is provided with an enabling output from the AND gate 14 for a time period which extends from the termination of the input pulse from the multi-vibrator 11 until the 70% duty cycle circuit 12 changes to its "on" state. This time interval is variable since the output pulses from the multi-vibrator 11 are of fixed duration whereas the total time interval between cycles of operation of the 70% duty cycle circuit 12 is longer at low speed operation of the engine and becomes increasingly shorter at higher speed operation. The time multiplying circuit 16 produces an output inhibiting signal when the 70% duty cycle 12 switches to its "on" state. The duration of the inhibiting signal is a multiple of the time interval which occurred between the end of the monostable output pulse and the turning on of the 70% duty cycle circuit 12. No current flows through the coil from the terminal 26 until the switch 24 is switched on by the drive circuit 22. This occurs only when all three inputs to an AND gate 18 are enabling inputs such a condition exists when the 70% duty cycle 12 is in its "on" state and the inhibiting output from the time multiplying circuit 16 terminates. At some high speed the off time of the 70% duty cycle circuit 12 becomes equal to the duration of the monostable pulse width. At this and higher speeds of the engine the time multiplying circuit 16 is rendered ineffective and no inhibiting signals are supplied by that circuit. The output of the AND gate 18 then follows the constant dwell output signals from the 70% duty cycle circuit 12 to operate the drive circuit 22 and the high voltage switch 24 as a constant dwell circuit for such high engine speeds. If the time interval between output pulses from the monostable circuit 11 exceeds the maximum amount which should occur in operation of the system, the time limiter circuit 28 causes a current limiter circuit 20 to produce a gradually increasing inhibiting signal to the AND gate 18. A gradual reduction in the output of the drive circuit 22 results.

Title: Improvements in or relating to power-assisted steering mechanisms
Inventor: FARMERY GEORGE KENNETH
IPC: B62D5/06
Filed: 1959-05-08
Abstract: 906,346. Steering vehicles. CLAYTON DEWANDRE CO. Ltd. April 29, 1960 [May 8, 1959], No. 15933/59. Class 79(5). A power-assisted road vehicle steering system wherein a double acting piston is actuated by compressed air comprises a control valve mechanism having, in a common housing, two valve assemblies each comprising an upwardly spring-loaded plunger 7 and a valve seat 11 closed by a spring- loaded valve 24. The plungers are located in sleeves 10 and have axial and transverse bores 8 and 9 and the sleeve has an annular recess 14 communicating by a passage 15 with the inside of valve seat 11 and with ports 16 leading to opposite ends of the piston. A flanged sleeve 19 provides a thrust surface. for the plunger spring 20 and the guide for an axially movable valve 22 which is spring urged, towards a seat 23. Upward movement of the plunger 7 is limited by engagement of a shoulder 7a with stops 21. The sleeve 10 is formed with an annulus 17 which communicates with the passage 9 and with a transverse bore 18 linking the two assemblies. In a chamber 3, open to atmosphere through a passage 6, is located a rocking lever 4 actuated by a link 25 connected to the steering mechanism, e.g. to the drop arm, the valve housing being mounted upon a fixed support. Compressed air is supplied to a chamber 12. In the "straight ahead" position, Fig. 1, the valves 22 and 24 are closed and both sides of the piston are connected through the passages and chambers 16, 14, 15, 8, 9, 17 and 18. Upon a slight steering movement, one or other of the plungers 7 is depressed and makes sealing contact with a valve face 24, sealing one side of the piston from the other. Then the valve 24 is moved from its seating and compressed air is admitted to one side of the piston. When a greater torque is applied to the steering wheel, the shoulder 7a contacts the valve 22 causing it to open and thus opening the other side of the piston to exhaust through the chamber 3, valve 22, passage 18 and the chambers and passages 17, 9, 8, 15, 14 and 16 of the other assembly creating a larger pressure differential. After a steering movement, a residual pressure always remains. The centering springs restore the mechanism to the neutral position after a steering movement. In a modification, Fig. 3, the rocking lever is actuated through a rod 28 secured to a bearing pad 29 of a ball pin 30 attached to a Pitman arm or drop arm 31 of the steering mechanism, the bearing pad being located in a unit attached to a drag link 27. The bearing of the ball pin comprises a pair of pads 29, 29a, biased to the position shown by a spring 34. When the steering torque exceeds the spring load, the pin 30 moves and thus operates the power assistance mechanism through rod 28. A follow-up spring 37 causes pad 29a to follow the movements of the pin 30.
