Abstract: 255,872. Caretta, E. July 22, 1925, [Convention date]. Pneumatic springs; fluid-friction vibrationdampers.-A fluid vibration-damper, described particularly for application to spring suspensions for vehicles, and comprising two communicating chambers one of which has flexible walls is connected at the outer end of the flexible chamber to one of the relatively moving parts, the other of which is connected to a plate or partition separating the chambers, means being provided to control the passage of fluid from one side of the partition to the other. In the form shown in Fig. 1. the unit comprises two flexible chambers 7, 14 secured at their remote ends on a hollow rod 23 which is connected to the axle 2 and is provided with an inlet valve 22 for the introduction of fluid. The adjacent ends of the chambers are secured to a ring 10 sliding on the rod 3 and secured to the vehicle frame 1, the ring being formed with cup-shaped members 17, 18 embracing the chambers 7, 14. The rod 3 is formed with ports 19, 20 which may be controlled bv valves to restrict the flow of fluid in both directions of movement. The flow of fluid through the rod 3 is, as shown, controlled by an apertured cylindrical member seated on an internal shoulder at the upper end of the rod, adjustment being effected by changing this member for another having an aperture of different size. The chambers 7, 14 are secured on the rod 3 between cup-shaped members 4, 5 and discs 16. In a modification, the cup-shaped members 17, 18 form part of the chambers the flexible walls of which are secured to flanged edges of the members 17, 18. In another modification shown in Fig. 3, the part 25 corresponding to the ring 10, Fig. 1, forms the partition between the two chambers 7<1>, 14<1>, a valve 27 being provided in the partition.

Patent GB-1518205-A (GB)
Title: Engine control circuit
IPC: F02P5/15
Filed: 1976-05-04
Abstract: 1518205 Timing ignition CHRYSLER CORP 4 May 1976 [13 June 1975] 18258/76 Heading F1B An engine control circuit, e.g. for timing ignition, comprises a transducer circuit, e.g. engine vacuum circuit 124, producing a signal representative of the instantaneous engine vacuum, an accumulation function circuit 122 including a pulse generator circuit 150 and an up/down counter circuit 170 adapted to add to and subtract from the count of pulses therein, a modulation circuit 126 producing the programmed engine control signal from the engine vacuum signal modified by the count in the counter circuit, and means to cause the counter circuit to add the input signal to its count when the engine is operating in one selected condition and to subtract it when the engine is operating in another selected condition. As described, the means is an idle stop switch 118 effective to cause the counter to add to its count when the engine is in a non-idle condition and to subtract from its count when the engine is idling. A coolant temperature switch 120 is effective to prevent vacuum advance until the engine has warmed up. The pulse generator 150 is controlled by idle stop switch 118, which also controls counters 172, 174, such that its frequency is higher when the counter circuit is counting down than when it counts up. The output from counter circuit 122 is fed as an analogue accumulation function signal on line 250 to the modulation circuit 126 in which it modifies the engine vacuum signal from a transistor 146 to produce an output vacuum advance signal from a comparator 302 which is representative of the product of the engine vacuum signal and the analogue accumulative signal. A vacuum advance inhibit circuit 128 cancels the engine vacuum advance signal when an engine idle condition exists. A TIC function circuit 130 is effective to give full vacuum advance when engine overheating occurs. Again, Fig. 7 (not shown), the idle stop switch 118 is connected solely as an input to the vacuum advance inhibit circuit 128, and the coolant temperature switch 120 is connected solely as an input to the pulse generator circuit 150. The pulse generator circuit does not therefore produce pulses until the engine is warmed up. Also the direction in which the accumulator counter counts is controlled by the output of the modulation circuit 126. The engine vacuum advance signal is fed to a summing junction 116 where it is added to advance signals from other unspecified advance circuits (104), Fig. 1 (not shown) and the addition is compared to a signal from a sawtooth engine crank angle circuit (105) to produce an ignition control signal.

Title: Improvements in and in connection with railway signalling
IPC: B61L3/04
Filed: 1921-07-09
Abstract: 184,030. Clarke, F. July 9, 1921. Track apparatus for actuating signals on trains and for stopping trains.-Apparatus for actuating signals or stopping-mechanism on trains consists of a track ramp movable about a vertical axis by means operated with the track signals, and a continuously rotating wheel on the train arranged to move along a transverse axis to operate a slide valve controlling the mechanism which is operated to caution or stop positions according to the position of the ramp. The track ramp 1 swings on a vertical pivot 2 and is held in contact, by a weight, with a step-up slide 3 operated by wires 7 in conjunction with the track signals; the parts are shown in their " line clear " positions in Fig. 1. When the signals are in the " caution " position the end of the ramp is moved to engage the step 3<b>, and in " stop " position to engage the step 3<a>. A wheel 8 is carried by a transverse shaft 9 on the vehicle, and is free to slide on the shaft while it is constantly driven from one of the vehicle wheels through the sleeve 10. A lever 12 is connected at one end to the sleeve 10 by a pin-and-groove connection, and at the other end to a slide valve working in a chamber 16, Fig. 14, with appropriate connections to the boiler and exhaust. When the ramp is in the position shown in Fig. 1, it is not engaged by the wheel 8, but when it is moved to the " caution " position it causes the rotating wheel 8 and sleeve 10 to move along the shaft 9 and so displace the slide valve. This admits pressure to the cylinder 19 and raises the piston 22, thereby operating the repeater signals 23, 24 to their " caution " positions. When the ramp is in the stop position, the lateral movement of the wheel 8 moves the slide valve to its extreme position, and the piston 22 is raised to its upper limit, thereby operating the repeater signals 23, 24 and the regulator 25. The slide valve and its actuating-member may be made to move in either direction from a medial position to provide for reverse running.
