Abstract: 1,041,875. Clutch control. HONDA GIJUTSU KENKYUSHO KABUSHIKI KAISHA. July 16, 1963, No. 28188/63. Heading F2L. [Also in Division G3] A fluid pressure regulator, particularly for a vehicle clutch control system, comprises a rotary casing housing a number of centrifugal valves in parallel between inlet and exhaust openings, and arranged to open at different rotational speeds so that the operating pressure is dependent upon the speed of the casing. The regulator 5 is driven by the vehicle engine 2 and delivers pressure liquid from a pump 4 to a clutchoperating cylinder 1, Fig. 1 (not shown). The liquid from the pump passes through an axial bore 6 in the regulator drive shaft 7 from which it passes through openings 17 in partitions 16 of a hollow disc 8 to the inlets 12, 12<SP>1</SP> of ball valves 13, 13<SP>1</SP> fitted with springs 14, 14<SP>1</SP>. Valve element 13 is heavier than element 13<SP>1</SP> but its spring is not stressed, whereas spring 14<SP>1</SP> exerts a substantial force on element 13<SP>1</SP>, so that as the speed of rotation increases the pressure rises in dependence upon the speed until valve 13 opens and the pressure rise is then governed by valve 13<SP>1</SP>. After passing through exhaust ports 15, 15<SP>1</SP> the liquid enters a space between disc 8 and casing 5 communicating with an exhaust pipe 19. The number of valves may be varied as required, and their individual characteristics determined by such factors as weight of valve element, spring loading, area of inlet port and distance from the axis of rotation.

Title: Improvements in or relating to relaxation oscillators
Inventor: HUGHES EDWARD PIERCE
IPC: H03K3/08
Filed: 1954-10-06
Abstract: 763,866. Pulse modulation circuits; pulse generating and gating circuits. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd. Oct. 6, 1954, No. 28743/54. Classes 40(5) and 40(6) A relaxation oscillator comprises two electric discharge-tubes which conduct alternately the tube having a common cathode resistor and the tube which acts as a cathode follower has its control grid connected to a pre-set positive voltage provided by a potential divider connected across the H.T. supply. Fig. 1 shows a relaxation oscillator in which if initially tube V1 is cut-off and tube V2 conducting capacitor C1 charges through resistor R3 until V1 conducts and the drop in its anode voltage reduces the current flow in tube V2 the voltage drop across cathode resistor R1 is reduced and then the conductivity of V1 increases the action being cumulative until V1 is conducting and V2 cut-off. Capacitor C1 now discharges through the grid/cathode path of tube V1 and capacitor C2 discharges through resistor R4 until tube V2 starts to conduct when the circuit reverts to its initial state. A low impedance pulse output may be taken at lead 10 from across cathode resistor Rl. The pulse repetition frequency may be changed by variation of the tapping of potentiometer R6 or the tapping may be set at such a point that the circuit functions as a monostable flip-flop, positive triggering pulses being applied to lead 11. The circuit may function as a frequency divider of pulses applied at lead 11 by adjusting the tapping of potentiometer R6 so that after a given number of applied pulses, V2 conducts, and changes over the circuit. The circuit may function to gate pulses applied at lead 11 the positive control pulses being applied to resistor R4 which is then disconnected from potentiometer R6. When the control voltage at R4 falls below a pre-determined value the pulses at lead 11 are of insufficient amplitude to cause tube V2 to conduct. In a modification shown on Fig. 2 when modulation signals are applied to transformer TR3 amplitude-modulated pulses are produced at output 12. When modulation signals are applied in antiphase to transformers TR1, TR2 duration modulated pulses are generated. Frequency modulated pulses are generated by applying the modulation signals to transformer TR2 alone.

Abstract: 797,921. Hydrostatic transmissions. SPLADIS SOC. POUR L'APPLICATION D'INVENTIONS SCIENTIFIQUES. Oct. 12, 1954 [Oct. 20, 1953; Sept. 13, 1954], No. 29340/54. Class 69 (2). [Also in Group XXVIII] An hydraulic motor or pump having radially disposed cylinders with pistons mounted to be operated from a control shaft 7 as described in Specification 757,348, has the liquid-inlet and outlet to the cylinders controlled by plates 13, 14, which are eccentrically mounted on the shaft 7 and adapted to make a non-rotary orbital motion such that each opening 19, 191 in the plates describes a circular path c, c<SP>1</SP> which brings it into and out of register with corresponding inlet or outlet port 20, 201 in the side of the casing of the motor or pump. The plates 13, 14 are so disposed in respect of their relative eccentricity that the inlet and outlet ports are opened and closed over half a revolution of the shaft 7 at the appropriate moment. To ensure a seal between the cylinders, plates and side walls 15, 16 of the casing, each cylinder communicates on the outlet side with a bore 21 housing a sleeve 23 accommodated in a separate socket 31 screwed into the cylinder, the sleeve being pressed against a washer 36 movable, but not rotatably, in the plate 14. The sleeve 23 is urged outwardly by a spring 25 against the washer 36 which in turn is pressed against a rib 26 of the casing 16. A small bleed hole 29 permits liquid under pressure to pass between the washer 36 and wall 16 within the confines of the rib 26 when the outlet holes 19<SP>1</SP>, 20<SP>1</SP> are in alignment, thereby preventing undue frictional grip between the washer and wall. When the outlet holes 19<SP>1</SP>, 20<SP>1</SP> are out of alignment the passage of liquid pressure between the washer and casing is permitted by the hole 19<SP>1</SP>. On the inlet side the arrangement is reversed with the bore hole being in the casing. In a reversible motor or pump a socket arrangement may be arranged in both the cylinders and walls of the casing at each port, so that they oppose each other. In this case two plates are provided each having washers 36 which press on opposite faces of a suitably apertured member spaced between the plates.
