Patent FR-2425101-A1 (FR)
Inventor: JAUNIN JEAN-PIERRE
IPC: G04C3/00
Filed: 1979-03-22
Abstract: In a timepiece having an electro- mechanical analogue display (hour and minute hands driven by a step motor) and also an electronic digital display for giving other information, a signal generator (LED 6) and a detector (photocell 7) are so arranged in relation to an element (wheel 5) coupled to the analogue display as to produce periodic signals for synchronizing the digital to the analogue display. As described the wheel 5 is turned by hour wheel 3 and its aperture 8 causes a signal to be generated at midnight. The signal is used to ensure that a digital date display is synchronized with the hands, especially after replacing the timepiece battery. Use in an alarm timepiece is also envisaged.

Title: IC engine ignition system - has control signal generator providing short ignition timing pulses supplied to monostable flip=flop input
IPC: F02P3/08
Filed: 1979-07-25
Abstract: The control of the closing angle is simply carried out by detecting in a wide speed range of the engine a constant closing angle. For this purpose is used a control signal generator (20, 14, 16) whose short ignition timing pulses form the control signals supplied to a monostable flip-flop (T1, T2). The flip-flop interval is adjustable in dependence on the duration of the previous closing time period for the circuit breaker. This period is detected as a proportional voltage across a capacitor, whose discharge with a constant current takes place in accordance with the height of the present charging. When a voltage level is attained, at which the monostable flip-flop is reset by the ignition timing pulse in its stable state, is the contact breaker is reclosed or forward controlled if a transistor takes over the contact breaker function.
Patent FR-2463955-A1 (FR)
Title: X=Y graphics tablet using conductive film - which is contacted to resistive plate to give voltage differentials dependent on distance of contact from centre of plate
Inventor: BLAEVOET GERARD JEAN-PAUL
IPC: G06F3/045
Filed: 1979-08-20
Abstract: The graphics tablet converts the pressure exerted by a pointed marker to analog electrical signals which define the pressure point in X,Y coordinates. A flexible conducting film (2) with a potential (V) applied to it through a resistor (R1) is stretched a few tenths of a millimetre above a resistive plate (1) which has terminals along each of its four sides linked through adjustable resistors (p1-p12) so that the resistors on any side are all connected via a resistor (R2) to earth and to an input of a differential amplifier (3,4). When the marker connects the conducting film to the resistive plate a voltage (V) is applied at that point in the plate causing a voltage to appear at the input of a differential amplifier. The voltage will depend on how far the contact point is from the centre of the resistive plate. Two differential amplifiers give X,Y coordinates as analog output voltages. The resistors connected to the edge of the plate (p1-p12) may be adjusted to compensate for material variations. A Schmitt trigger circuit (5) connected to one amplifier input can be used to signal data availability.

Title: System of propulsion for ships - comprises two articulated plates oscillating in enclosed channel beneath hull
Inventor: KERANDRAON OLIVIER DE LA ROCHE
IPC: B63H11/06
Filed: 1979-12-06
Abstract: The fluid pump has two plane surfaces (1,2) which are pivoted, and oscillate in a channel formed by the hull (9). A lower wall (10) has a height of half the distance between the upper and lower walls (9,10). As the surfaces (1,2) are driven together the pressure difference causes the short ends of the plates (1,2) to approach each other until they touch, thus bringing the long ends together expelling the water between the plates. Vibrations are eliminated by balancing opposing movements of the plates.

Title: Regulating valve for double acting hydraulic jack - uses two spring loaded valves to normally close hydraulic passages which allow extra fluid flow when pressure differences are excessive
Inventor: BESSON LOUIS
IPC: F15B11/05
Filed: 1980-01-09
Abstract: A double acting hydraulic jack which controls the tilt of the lifting column of a forklift is manually controlled (13) to vary the connection between the hydraulic pump (16) and opposite sides of the actuating piston (9) fixed to the actuating rod (6). The hydraulic pressure in the actuating cylinder (7) is controlled by a regulator (24) and a safety 'parachute' valve is provided by a fluid velocity sensitive valve (18) on the outflow side (11) of the actuating cylinder when the column is loaded. The regulating valve (24) is interposed in the supply lines (14,15) to both sides of the actuating cylinder (7) and has sliding valves (33,39) spring loaded (35,41) from both ends to normally close the valves, leaving a small fluid passage for each supply line. If a pressure imbalance, sufficient to overcome spring force, arises between the supply and load hydraulic lines the valves open to allow extra fluid to pass.

Title: Liq. helium pump with superconductive electromagnetic drive - capable of working in magnetic fields of several tesla density giving constant differential pressure and constant flow
IPC: F04B17/04
Filed: 1980-04-14
Abstract: A liq. helium pump with a superconductive electromagnetic drive has a fixed superconductive exciter coil joined to the body of the pump and a mobile element of superconductive construction across the field of the exciter coil and fixed to the piston of the pump. The superconducting electromagnetic drive consists of an electromagnet with annular air-gap placed in the pump body and enclosed on all sides by a superconductive magnetic screen. The electromagnet has a ferromagnetic core which is connected at one front part to a ferromagnetic yoke surrounding the core, which forms with the core an annular air-gap in the region of the other front part. The core carries a superconductive exciter winding. A superconductive plunger coil is placed in the annular air-gap, coaxially with the superconductive exciter winding, on a coil holder displaceable in the direction of the axis of the electromagnet with annular air-gap. The superconductive drive device is free from construction elements lying across the pump body, and the pump can work without perturbations even in strong external magnetic fields of a density of several teslas. It gives a constant differential press. between the inlet and outlet of the pump and consequently a constant quantity at a suitable flow rate.
