Title: Electronic fuel-injecting system for internal combustion engines
IPC: F02D41/32
Filed: 1971-04-22
Abstract: 1347712 Fuel injection systems SOC DES PROCEDES MODERNES D INJECTION SOPROMI 22 April 1971 [28 April 1970] 10843/71 Heading G1N In an I. C. engine fuel injection control system a capacitor 5 is charged to a value dependent upon engine operating conditions during a first stage of each engine cycle, and during a further stage during which injection takes place, the capacitor 5 is discharged, to initiate injection, at a rate determined by engine conditions, the duration of injection being determined by the time it takes for the discharge voltage to reach a level adjustable in dependence upon engine conditions. As shown, Fig. 2, capacitor 5 is charged through a transistor 2, rendered conductive by an engine controlled pulse generator D, to a voltage determined by the value of resistance 10 controlled by engine conditions. During the further stage, transistor 2 is blocked and transistor 8 is rendered conductive to discharge capacitor 5, at a rate determined by resistance 11, through a programme-controlled uni-junction transistor 14, which initiates injection via amplifier A. The injection duration is determined by the time it takes the capacitor discharge voltage to reach the threshold set in the control electrode of the transistor 14 by a potentiometer 21 controlled by engine conditions. In an alternative, Fig. 3 (not shown), the generator D is constituted by an oscillator which is associated with a member having alternate metallic and non-metallic parts rotated by the engine, the oscillator oscillating only in the presence of the metallic parts. The charging of capacitor 5 is determined by the voltage applied to the base of transistor 2 from the oscillator via a capacitive divider and rectifying and filtering arrangement M3, the capacitive divider being controlled by engine conditions. Capacitor 5 is discharged through the transistor 14 when a transistor switch is operated through another rectifying and filtering arrangement D1 at the output of the oscillator. In a further alternative, Fig. 4 (not shown), integrated circuits are provided, the generator D again being provided by an oscillator whose output is connected to a pair of NAND gates acting as switches, one controlling charging of capacitor 5 and the other its discharging. The uni-junction transistor is replaced by a trigger device.

Title: Improvements in and relating to combined electric control and protective systems
IPC: H02H7/00
Filed: 1934-04-11
Abstract: 436,460. Protective cut-out arrangements. TYERS, P. D., 7, Devereux Drive, Watford, Hertfordshire. April 11, 1934, No. 10961. [Class 38 (v)] A circuit for remote control of apparatus such as a mining motor 5 comprises a rectifier 7 and pilot switch 6 at the control end, a polarized relay 13 for effecting the control and an A.C. source such as a transformer or rotary converted at the main switch end, and a pilot wire 8 and a power conductor 1 supplying the controlled apparatus, the arrangement being such that the controlling mechanism is rendered inoperative should a fault such as would render the control circuit ineffective develop in the control circuit. The motor 5 is connected over a trailing cable 1, 2, 3 to starting mechanism at the gate-end controlled by the polarized relay 13 or other relay that can discriminate between A.C. and D.C. or pulsating current. Closure of 6 energizes the relay which energizes the starting mechanism either directly or through a further relay. If the pilot circuit becomes opened, the relay 13 is de-energized and the motor 5 disconnected, whereas if the leads 8, 1 become connected, the output of the rectifier is shorted and 13 is de-energized. If 8 gets earthed, the phase-wire 1 becomes earthed and the relay 13 is rendered inoperative. Fuses 18, 19 or normal earth leakage protection would deal with such a fault. The system is also associated with a known earth-continuity protective arrangement comprising a Wheatstone-bridge, one arm of which is formed of the earth-lead 28 in series with an auxiliary lead 29. If 8 comes into contact with 28, 29, the consequent earthing will produce de-energization of 13 as described above. Fig. 3 shows a multiple cable comprising power leads 21, 22, 23, earth lead 24, a screen 25 serving as the pilot lead, and an earth screen 26, but a five-core cable could be employed, Fig. 2 (not shown). The invention is applicable also with non-flexible cables, to single phase systems, and to systems wherein the starting mechanism is adjacent the motor and the control point at a distance, as in goods or passenger lifts.

Title: Hydro-pneumatic spring suspension element
IPC: F16F9/092
Filed: 1965-03-16
Abstract: 1,044,102. Hydro-pneumatic suspension units. FICHTEL & SACHS A.G. March 16, 1965 [March 25, 1964], No. 11079/65. Heading F2S. In a self-levelling hydro-pneumatic spring suspension element during normal amplitude vibrations of a differential piston 2 in a working cylinder 1 damping is obtained as liquid flows to and from a gas spring chamber 6, 29 through cylinder openings 19 and between upper and lower cylinder chambers through piston ports 20 controlled by a valve 39 the plunger 14 of a pump, connected to the piston 2, working in a cylinder in a pump body 7 to suck liquid past a one-way valve 27 and through a pipe 28 communicating with a reservoir 16 in the upper end of the suspension element and pump it past a one-way valve 25 in the body 7 into a highpressure accumulator 9, 13. Pumping ceases, so that over pressure in the accumulator 9, 13 is avoided, when a separating piston 34 in the reservoir descends sufficiently to abut a spring ring 33. Excessively large strokes of the piston cause the head of the piston 2 to abut a spring 22 which, through a pin 23, opens the valve 24 so that liquid from the high-pressure accumulator 9, 13 flows into the working cylinder 1, and a port 21 in the cylinder to communicate with a port 32 in the reservoir so that fluid can flow from the working cylinder space back to the reservoir 16. One-way valves 11, 17, 31 allow gas under pressure to be supplied to the high-pressure accumulator 9, 13, the gas spring 6, 29, and the-reservoir 16, 30. In a modification, Fig. 2 (not shown), the piston port 21 opens directly into the reservoir 16, 30, the same resilient diaphragm 36, 37 being used for both the gas spring 6, 29 and the reservoir 16, 30. An apertured wall 35 in the reservoir provides a stop for the diaphragm 37 to limit withdrawal of fluid by the pump 7, 14.

[Class 23] [Also in Group VIII] A laundering machine which automatically changes over from a washing process to a centrifuging process comprises a holding drum 3 which is rotated slowly for washing through a clutch drive 5, or quickly for drying through a clutch drive 4. The quick drive from the clutch 5 to the drum shaft 2 may be by way of countershaft pinions 12, 11, 10, 9 or equivalent gearing. The clutches 4, 5 are thrown in and out of action by a lever 13 the lower end of which,is slidably held under spring pressure in a slot in a laterally movable shaft 14 normally pressed to the right by a spring 18. A lever 23 journalled at 24 is pivoted at one end to the shaft 14 and at the other end carries a pin 25 sliding in a slot 26 in a rod 27 movable axially by the action of opening the door of the drum 3. The shaft 14 is held to the left with the spring 18 compressed by a detent 35 pivoted at 28 and having a notch 29 which takes over a pin 30 on the lever 23. The end of the pawl 35 bears on a disc cam 31 rotated by gearing from the motor 6. The action of opening the drum door moves the rod 27 to the right sufficiently to swing the lever 23 anticlockwise till the pawl 35 takes over the pin 30. This swings the lever 13 to engage the washing clutch 5 which functions to turn the drum slowly till the cam 31 lifts the pawl 30 and releases the spring 18 to put the high-speed drying clutch 4 into engagement.
