Patent FR-2274851-A1 (FR)
Title: Stopcock with motorised operation - can be fitted to existing hand operated valve, assisted by inertia energy of rotor
IPC: F16K31/05
Filed: 1974-06-13
Abstract: The stem of the valve is connected to a shaft (10) projecting from the motor, this stem being guided between pillars forming a mounting for the motor. The motor shaft is threaded into a spool (12) inside the motor casing (15), this spool being surrounded by the rotor and the stator (22). Above and below the spool are thrust bearings (20) and sleeves (13, 14) incorporating sets of spring washers (16). In operation, one set of washers is compressed. The rotor turns and a key (23) on its surface meets with another (24) on the spool to drive it round. The inertia and the stored spring energy gives positive working.

Title: Micro-lightning arrester allowing controlled discharge - across inert gas atmosphere between alloy metal electrodes with low expansion coefficient
IPC: H01J17/40
Filed: 1974-07-15
Abstract: A micro-lightning arrester comprises hollow cylindrical outer electrode closed at one end, made of iron, nickel cobalt alloy called KOVAR (Trade Mark) and a cylindrical inner electrode coaxial to and of the same material as the outer electrode. This inner electrode extends to within a few tenths of mm. of the closed end of the outer electrode to guarantee a discharge will be produced. The two electrodes are joined by a glass bead which closes the open end of the outer electrode and the space in the outer electrode is filled with a gas, e.g. argon with added tritium, introduced via the bore of the inner electrode which is then sealed. This filler gas is at a press. between 50 and 100 torrs. inclusive. The two electrodes will short-circuit under a dispersion of power of 10 watts with compression applied along the longitudinal axis of the electrodes. For installation in subscribers' telephone lines. The device gives stable, uniform performance and has characteristic of a starting voltage which varies with the rate of increase of input impulse. The electrodes short circuit if an abnormal overload occurs. This device is far easier to make than previous arresters.

Title: Gas bottle charging head - has spring loaded differential piston shutting off outlet from bottle
Inventor: CAZALAA JEAN-MICHEL
IPC: F17C13/04
Filed: 1974-11-05
Abstract: The head is for bottles containing compressed, liquefied or dissolved gas, and incorporates a differential piston working in a cylinder connected to the bottle. The smaller active face of the piston is directly subjected to the pressure in the bottle, and the larger one to the action of a spring and, when in the shut position, to a back-pressure equal to that in the bottle, so that the piston shuts off the gas outlet. The back-pressure chamber can be connected to atmosphere. The cylinder can be connected to the bottle via an annular body, to allow adjustment of its angle in relation to the body when the head is fitted in place.

Title: Second stage pressure release valve for diving mask - with release pressure variable according to the first stage pressure
IPC: A62B9/02
Filed: 1975-01-31
Abstract: Air from the first stage comes in through the air passage (1) which connects with the passage (3). The upper part of this passage is closed by the valve (4). The valve is spring loaded (12) and has two rings (7, 8) which form a seal between the cylinder walls and the piston. The lower part of the piston is drilled to allow the air space (3) to connect with the circular space (9) so as to balance the pressure between the faces (10, 11) of the piston. The air pressure regulation obtained by the piston (4) allows the air aspired by the diver to be supplied at the correct pressure irrespective of depth.

Patent FR-2305497-A1 (FR)
Title: Tool for tacking hide in permanent flexible support - avoiding time consuming manipulation of individual tacks
IPC: C14B17/08
Filed: 1975-03-25
Abstract: Tool for tacking hide comprises a flexible strip of suitable material, in which a row of tacks is permanently disposed and which allows rectilinear or curved tacking. Each tack is maintained in the retracted position by a spring which is compressed when an impact is applied to the head of the tack. In operation, the flexible support bearing the tacks is simply laid on top of the hide, providing it with a curved or rectilinear shape as required, and the tacks are successively embedded in the hide by hammering them in. This avoids the length and tedious process of manipulating the tacks individually thus increasing productivity considerably The shape, length and construction of the tool may be varied as desired.

Title: Mixing valve with inlet pressure compensation - has double piston stage reacting to pressure variations to regulate flow through compensating orifices
IPC: G05D23/13
Filed: 1975-05-13
Abstract: A mixing valve for achieving a constant temperature flow from hot and cold water has a pressure compensating stage to eliminate the effects of supply pressure variations. An axially constrained valve sleeve is located in a housing block and may be adjusted rotationally. The sleeve has two pistons that are spring loaded into contact with two temperature sensitive bellows, one of which reacts to temperature increases and the other to decreases. Inlet flow rate is initially set by rotating the valve sleeve to cause two cam tracks to open the spring loaded inlet valves. The two flows pass through orifices into the central mixing region.

Patent FR-2316503-A1 (FR)
Title: Precisely adjustable discharge valve for gas lighters - has conical-cylindrical piston mounted in cylindrical seal below porous ring retained by sliding collar
IPC: F23Q2/173
Filed: 1975-07-04
Abstract: The primary orifice of the valve has a two stage seal. In the first stage, a sliding, spring loaded piston seals the orifice as it enters a cylindrical sealing ring. A flared skirt of the piston encounters the lower inside edge of the seal. Just above the piston is a porous ring retained by a sliding collar located in a cylindrical guide. The actuator button is connected to the piston shaft via a screwed connection which allows the discharge rate to be preset by altering the compression of the porous ring. The liquid fuel expands through the porous ring and passes to the nozzle via annular and radial passages. Rotation of the piston is prevented by makings its lower section hexagonal and making the guide passage a complementary shape. The height of the cylindrical part of the piston ensures that there is a delay after pressing the button before gas is discharged and similarly the flow is cut off before the button is completely released.
