Title: Improvements in or relating to vehicle brake and accelerator controls
IPC: B60T11/10
Filed: 1955-10-31
Abstract: 804,649. Controlling vehicles. WATSON, R. A. Oct. 31, 1955 [Nov. 5, 1954], No. 31018/55. Class 79(5) [Also in Group XXXIV] A combined brake and accelerator for a motor vehicle comprises a pedal 10 mounted for pivotal movement about two axes, and a connection from the pedal 10 to a fuel metering device 80, and to a master brake cylinder 14, whereby on movement of the pedal about one axis the device 80 is operated, and o.m movement about the other axis the cylinder 14 is energized and the device 80 is adjusted or closed. The pedal 10 is pivotally mounted at 40 on a member 36, which is rotatable in a ball bearing housing 42 in the floor boards 12 of the vehicle..The member 36 is connected by a linkage 54, 58, 68, 76, to the fuel metering device 80 so that on rotation of the pedal 10, the device 80 is moved towards an open position. Rotation of the pedal 10 is effected by the foot acting upon a flange 84. The heel 86 of the pedal 10 is pivotally connected to a rod 32 which is co-axially mounted within, and slidable relative to, the member 36. The member 32 is connected to the piston of the master cylinder 14. The links 76, 68, between the member 36 and the fuel metering device 80, comprise a piston and cylinder. 'The cylinder 68 is connected by a pipe 108 and valve 122 to a cylinder 92. The other end of the cylinder 92 is connected to the master cylinder 14. A floating piston 102 separates liquid in the master cylinder 14 and lower portion of the cylinder 92, from the liquid in the upper portion of the cylinder 92, the pipe 108, and the cylinder 68. In order to effect braking of the vehicle, the pedal 84 is given a fore- and-aft movement so as to reciprocate the rod 32 and apply pressure in the master cylinder 14. This supplies the vehicles brakes in the usual way, and also develops pressure on the floating piston 102 in the cylinder 92 which in turn applies pressure to the cylinder 68. Pressure thus acts on the piston rod 76 to move, the fuel metering device towards the closed position. Should the latter already be in a substantially closed position, a switch 112 actuated by a link 78, closes a circuit 114 to energize a solenoid 118, and so close the valve 122. This prevents braking actions from further closing the fuel metering device and maintains suitable engine idling. In a simpler construction (Figs. 1 to 4, not shown), the cylinder 92 and valve 122 are dispensed with, the master cylinder 14 and cylinder 68 being connected by a single length of pipe. The piston rod 76 and cylinder 68 could, alternatively, be actuated by the action of vacuum from the inlet manifold of the engine.

Abstract: 628,132. Injection pumps. PESCARA, R. P. Oct. 21, 1946, No. 31283. Convention date, Oct. 22, 1945. [Class 102(i)] In an accumula tor injection sys tem, a closure member of a valve is interposed bet ween the accumu lator chamber and the injector and is actuated either directly or indirectly by the plunger of the pump that feeds the chamber. In the arrangement shown in Fig. 1, the accumulator chamber 6 has an accumulator piston 7 and is fed with liquid by a pump piston 1 through a spring-loaded valve 9 that is mounted in a valve 13 that is opened by contact with the piston 1 to allow liquid to flow from the chamber 6 through channel 14 and passages 15, 12 to the injector. The edge 2 on the piston controls the amount delivered to the space 6 which is also fitted with a relief valve 10. The accumulator piston engages an intermediate member 20 loaded by a spring 7a and in addition air under pressure may be supplied to the chamber 24. In a modification, the valve 9 is omitted and the valve 13 is opened when the piston 1 almost contacts it by the liquid pressure developed in the pump cylinder. The valve may be opened by a member rigidly attached to the piston or by a liquid pressure developed by this member.

Title: Electric pulse re-iterating circuits
IPC: G11C21/00
Filed: 1947-12-05
Abstract: 640,677. Pulse storing circuits. STANDARD TELEPHONES & CABLES, Ltd. Dec. 5, 1947, No. 32117. Convention date, April 26, 1946. [Class 40 (vi)] A pulse storage system comprises a pulse repeater associated with a delay device which has its input coupled to the output of the repeater and its output coupled to the input of the repeater so that an input pulse circulates round the system a number of times and is re-shaped during each circulation to compensate for the attenuation and distortion produced in the loop. Fig. 1 shows a pulse storage system 1 and pulse selecting system 15 for use in a pulse multiplex system. The pulses at the output of a receiver 13 comprising a marker pulse 7 and pulses 8-11, each corresponding to a communication channel are position modulated and are applied to amplifier 3, the output of which is limited and shaped and applied back to its input via delay 2. The delay is adjusted so that all of the pulses are applied to the amplifier input before the marker pulse has reached the amplifier input again. When switch 14 is closed the marker selector 16 selects the marker pulses 7 and applies them through an adjustable delay 17 to open gate 18 and let through one of the pulses 8-11 corresponding to a given channel to the demodulator 20 and utilizing device 21. Fig. 2 shows the use of a storage system in a synchronized pulse repetition rate multiplier. A positive going input pulse applied at A cuts-off valve 23 and is amplified by valve 24 to circulate via B and C to the input of valve 23 which in the absence of a further pulse at A amplifies and recirculates the pulse in the system. When a further input pulse applied at A coincides with a pulse at C the circulated pulse does not pass valve 23 and the pulse at A is amplified by valve 24 and circulates in the system. The delay of device 27 is made small compared with the interval between input pulses so that any given pulse passes round the system several times before the next input pulse appears and the output pulses of higher repetition frequency may be derived at points B or C.
