Patent FR-2278996-A1 (FR)
Title: Shock absorber for motor vehicles - in which damping action is independent from plunger position or speed
Inventor: HEYMANN BERNARD RUDOLPH
IPC: F16F13/00
Filed: 1974-07-19
Abstract: The damper consists of an elongated cylinder with closed end walls, in which a piston is mounted. The bottom wall of the piston divides the cylinder into a high pressure and low pressure chamber which are filled with a hydraulic medium. the piston wall has an opening with non-return valve which connects the two chambers. At the low pressure side of the piston, a cover which forms a pressure regulating chamber, is cylindrical in shape, a spring loaded valve mounted in this chamber covers a valve opening in the piston. Holes in the cover connect the pressure regulating chamber to the low pressure chamber when the valve is open. Holes in the valve connect the high pressure to the pressure regulating chamber.

Title: Transistorised horizontal deflection circuit - has an H.V. transformer and a voltage multiplier for H.V. generation
IPC: H03K4/08
Filed: 1974-11-04
Abstract: In order to protect the transistor horizontal deflection output stage against voltage and current surges occurring during spark-over or breakdown of capacitors in the voltage multiplier, a diode and a decoupling resistor are connected in parallel behind the transistor horizontal deflection output stage, so that when positive breakdown pulses arrive from the voltage multiplier, the diode is blocked and the pulses reach the h.v. transformer only through the decoupling resistor. The diode in parallel with the decoupling capacitor is inserted between the voltage multiplier and the h.v. transformer secondary winding, or between the voltage multiplier and the horizontal deflection output voltage, (switching transformer).

Title: Pneumatic logic circuit element - comprises body in which fluid controlled sliding piston opens or closes certain orifices
IPC: F15C3/02
Filed: 1976-02-02
Abstract: Pneumatic logic circuits comprise a body with several orifices in which sliding elements open or close certain of the orifices. Several chambers are formed which can be interconnected to provide complex logic elements. A pneumatic logic element comprises a longitudinal body (4) containing a piston element (1) which slides within a cylindrical cavity (3). Two constant volume chambers (6, 7) are formed by two smaller diameter sections (8, 9) defined by ends (10, 11, 12) on the piston. Two stoppers (18, 19) enable control chambers (26, 27) to be formed whose volumes are varied according to piston position. Fluid injected into these chambers causes the piston to move to vary the volumes. This puts one orifice (5) into communication with one or other of the two other orifices (H, J) to form an OR gate.
