Title: Fuel injection regulator system - has piezoelectric crystal to vibrate ball valve in jet nozzle
IPC: B05B12/00
Filed: 1975-12-10
Abstract: The fuel jet (2) is a fuel tight sliding fit into the air induction pipe (1) and is vibrated by a piezo-electric crystal corresponding to the strength of alternating currents applied to its terminals. The fuel jet nozzle contains a housing with fuel openings (16, 20) to allow fuel to enter from a supply boring (16a) and a ball valve (15) which is pressed onto the valve seat (14) by fuel pressure to keep the valve closed. When a suitable alternating current is applied to the piezo electric crystal connections, an ultrasonic vibration is set up in the fuel nozzle which causes the ball valve to leave its seat and allow fuel to be sprayed into the air induction pipe. Electrical feed back signals are used to vary the electrical energy fed to the vibrator unit.

Title: Door lock safety device - uses clip passed through perforated bent strip to engage head of key to prevent turning
IPC: E05B13/04
Filed: 1975-12-17
Abstract: The device to prevent an ordinary lock from being operated from outside uses mechanical blocking from inside. It consists of a bar (a) bent into an elongated U shaped with one arm (b) slightly longer than the other (a) with a small strip (B) extending from the longer one. The two arms each carry a row of holes so that a bent pin (C) can be passed through. The key is turned in the lock, with its ring shaped head horizontal. The strip (B) is inserted into the part of the keyhole thus freed, with the head positioned between the arms (a, b). The pin is then inserted through two holes and the head of the key, so that it cannot be turned.

Title: Sensor for servo assisted steering - with strain gauge to monitor force on steering column
Inventor: HARDING GEOFFREY GEORGE
IPC: B62D5/065
Filed: 1976-09-10
Abstract: The steering column is linked to the steering rods by a servo powered link (15) in which the length of the link is increased telescopically by the hydraulic servo force, linked to a pump (21). The pump is only switched on when the force on the steering column is above a set limit, as determined by a strain gauge (36). The strain gauge is linked to the control circuit (38) by a coiled cable (37) around the steering column. The gauge output is amplified and passed to the pump control. The servo is only used as required and thus saves fuel over long periods.

Title: Control of automobile hydrostatic transmission - has steering wheel movable about two perpendicular axes for similar or differential positioning of two control rods
IPC: B62D11/18
Filed: 1976-10-20
Abstract: The control system is designed to control the equal or differential displacements of two movable elements with respect to a median position. The system has a control shaft (1) which rotates about its longitudinal axis (A-A). The shaft (1) is hinged around a second axis (B-B) perpendicular to the longitudinal axis (A-A). A pinion (4) is fixed to one of the ends of the shaft (1) and a steering wheel (3) is fixed to the other end. The system has two elements (6a, 6b) which are hinged on the second axis (B-B). Each element (6a, 6b) has a series of teeth (5a, 5b) arranged in an arc, which mesh with the teeth of the pinion (4). Levers (7a, 7b) and rods (9a, 9b) transmit to the movable elements (10a, 10b) equal displacements caused by rotation of the shaft (1) around the second axis (B-B). The system also transmits to the movable elements differential displacements when the shaft is rotated about its longitudinal axis (A-A).

Title: Opto-electric target detector - has movable transparent mask fitted with grills which produce modulation of given frequency during fraction of mask movement period
Inventor: ROBIN LEON
IPC: G01S3/787
Filed: 1977-04-13
Abstract: The detection and location system is of the amplitude modulation type. It uses an optical circuit which receives and focusses incident radiation from an observed field. It has a movable mask fitted with transparent grills on an opaque base which passes periodically transversally over the optical axis. The periodic transversal movement produces modulation of a determined frequency during a fraction of each period of movement. The system has a photodetector element and a pass band filter which delivers a carrier at the determined frequency amplitude modulated by a signal of frequency corresponding to the period. The system has also a demodulation circuit a modulation signal filter circuit and a phase analyser circuit. The grills are distributed along a number of optical tracks (Pl-Pn) to produce as many distinct frequencies (F1-Fn) during the fraction of the movement period (TD). The pass band filter circuit (5) is of the switchable type. Its central frequency presents successively the different values of track frequency, each during a period at least equal to the transverse movement period.
