Patent FR-2273173-A1 (FR)
Title: Ignition system for internal combustion engine - maintains constant duration of spark independently of engine speed
IPC: F02P3/045
Filed: 1974-05-31
Abstract: The system utilises an electronic circuit which can estimate the duration of one cycle of ignitiona nd can also fix the time of ignition with reference to the engine cycle so that the circuit of the ignition coil is opened and closed to provide a constant period of coil energisation at the precise phase of the engine cycle. This is achieved by using a condenser which retains a predetermined level of the charge acquired during the previous cycle and is then allowed to discharge at a constant rate by means of an isolating diode, a storage condenser and a transistor associated with a resistance.
Patent FR-2273685-A1 (FR)
Title: Engine fuel and wear economiser - extra spring in accelerator motion takes effect past optimum performance point
IPC: G05G5/03
Filed: 1974-06-07
Abstract: A vehicle engine fuel and wear economiser works on the principle of making the accelerator travel harder, by using a spring or similar device. This comes into effect once the accelerator is past the point of optimum performance of the engine. It also has the advantage that a driver is constantly aware of the point past which performance deteriorates. The limiting point which can be the speed of engine rotation can be varied and full performance is always available.

Title: Method of communication by cerebral waves - electrode system placed on and interconnecting two subjects
IPC: A61B5/0476
Filed: 1974-06-19
Abstract: A method of communication by cerebral waves, consists of placing on the subjects an electrode arrangement and detecting the waves emitted by the brain of the first subject to transmit them via electric or radio electric means. These signals are then reinjected into the brain of the second subject. The electrode systems are placed on the skulls of the subjects in the neocortex zones and on the occipital lobe. Each electrode placed on a precise point on the skull of the first subject has a corresponding electrode placed on an identical point on the skull of the second subject.

Title: Adjustable setting thermostatically controlled steam valve - has pressure spring balanced valve-head to minimise seat wear
IPC: F16K1/52
Filed: 1974-06-21
Abstract: The valve body is cylindrical with the inlet and outlet on opposite walls. The valve head is a hollow cylinder with an internal shoulder at its upper end co-operating with the enlarged end of a rod which is attached to the operating handwheel. A spring pushes the valve head against the end of the rod. The thermostat filter to the lower end of the body carries the valve seat which is pressed against the valve head when the temp. rises. The thermostatic pressure is limited by the spring and the steam pressure is balanced by the shoulders. Turning the handwheel adjusts the temperature setting.

Title: Keyboard telephone for long lines - uses speech loop current to power MOS circuit
Inventor: BELFILS ALBERT
IPC: H04M19/08
Filed: 1974-08-12
Abstract: The speech parts (3) of this telephone are connected across the line via two series transistors (13, 61) one of which provides a stable voltage to an oscillator circuit (10) whose rectified output is connected to a MOS clock generator (6). This is controlled by a keyboard dial. During calling, one output (14) of the MOS circuit breaks the series circuit of the speech circuit and another output (8) saturates a shunt transistor (9) across those speech circuits in coincidence with the signalling code. In this way, signalling power is derived from the speech loop current and the circuit is designed to operate on very long lines.

Title: Gas analyser pulsed infra-red light source - filaments switched and current regulated to replace motor-driven shutter
IPC: H01K1/02
Filed: 1974-12-10
Abstract: A pulsed infra-red light source for a gas analyser consists of filaments supplied with a variable current in any required sequence. The number of filaments is chosen according to the required pulsing frequency, and replace a conventional type of IR-light source consisting of a motor-driven shutter in front of a single IR-emitting filament. Using several switched filaments avoids the need for a shutter and its attendant motor. The choice of the number of filaments therefore corresponds to the number of rotary shutter arms, and the choice of pulsing frequency to the motor speed.

Title: Shock absorber for door actuating mechanism - has plate brake coupled to door by rack and pinion device
IPC: E05F5/06
Filed: 1975-03-10
Abstract: The shock absorber acts against the force of the door closing spring. The shock absorber has a linearly moving piston and the plate brake axis of rotation is arranged at right angles to the travelling axis of this piston. This brake ensures continuous braking of the closing door up to full closing. The shock absorber piston is coupled by its rack teeth to the rotating pinion teeth of the plate brake assembly which is held within the housing covered by plate. The plate brake has a number of internal and external plates which are sandwiched together. These plates are pressed together by a dished spring in the axial direction. The spring force is adjusted by an adjusting screw. The brake has a freewheeling clutch for ensuring that the brake does not interfere with the door opening movement. This brake force is uniformly distributed on the plates and the brake has a long life.

Title: Elimination of fixed and parasitic radar images - involves digital processing of echo phase comparison circuit outputs, and use of reference signal
IPC: G01S13/524
Filed: 1976-06-01
Abstract: Fixed object return radar echoes with a constant phase relationship to a reference signal while moving objects return variable phase signals. The phase comparison of these signals is converted into digital words for elimination of fixed and parasitic echoes while retaining moving target echoes. It-phase and quadrature radar signal resulting from reception of echoes are compared (37) with reference signal phasing to produce signals (39, 41) which are then converted (10) from analogue signals into digital words. These workds give echo distance and are processed (48, 50) by combining part of workd from one exploration with part of another exploration to produce correction signals representing average Doppler speed. Further combination and processing is effected to eliminate parasitic moving echoes.

Title: Magnetic coupling for video pickup arm - includes pot magnet system to give faithful reproduction from video track
IPC: G11B3/08
Filed: 1976-09-17
Abstract: The separable coupling is for the arm of a video disc reproducer. A first coupling element (54) on the end of the arm (51) is of magnetisable material. A second coupling element in the form of a support (64) located on the support (34) is likewise of magnetisable material and has walls enclosing a chamber (70) containing a permanent magnet (71) arranged centrally so that an annular gap is formed. The first coupling element can be brought into proximity with the face containing this annular gap leaving a gap between them which is greater than the gap between the permanent magnet and the walls of the chamber, so as to ensure the flux between the magnet and the walls is greater than between the magnet and the coupling plate. This ensures a true transfer of periodic movements.
