Title: Pressure measuring device for corrosive laser gas - uses monochromatic light source in gas absorption band and photodetectors illuminated directly and via gas, supplying signals to processor
Inventor: PEZOT JACQUES
IPC: G01L11/02
Filed: 1981-06-25
Abstract: The arrangemnt is used for gases in which the absorption spectrum contains at least one band. A generator emits monochromatic light whose wavelength is inside the absorption band of the gas. A sensor measures the beam transmitted through the gas and a reference sensor measures directly the beam emitted by the generator. Both sensors are connected to a processor which calculates the ratio between the energy of the reference beam and the energy of the transmitted beam. This ratio represents the gas pressure. A converging lens and a diaphragm are placed between the light generator and the gas and a band-pass interferential filter after the gas. The lens and diaphragm may be mounted on a coaxial tubular support separate to another on which are mounted the filter and receiver. Between the two supports, and perpendicular to their axes is situated a cylindrical transparent tube containing the gas.

Title: Elastic balls for games on rough surfaces - having dense core within deformable but inelastic surface
IPC: A63B37/06
Filed: 1981-07-01
Abstract: A ball required to give a true bounce for a game played on a rough surface has a heterogeneous structure featuring a combination of a dense core, an external zone which is highly deformable with a low elastic reaction and an intermediate zone which is less deformable and more elastic. When the ball strikes an opposing surface, the core can maintain its original direction of movement while the ball surface adapts to the opposing profile. The core motion is reversed by the elasticity of the intermediate layer without effect from local variations in the profile of the opposing surface. Opt. the sphere is made of concentric layers fabricated to different levels of density and elasticity; alt. the ball may be made as a homogeneous body of porous polyurethane foam into the centre of which is injected a fast-curing rubber. As the rubber diffuses out radially throughout the sphere, its concentration decreases to produce progressive reductions in the rubber loading levels as curing proceeds.

Title: Grid mfg. method for electrical button contacts - is formed from flat sheets and is used particularly with nose cone assemblies
Inventor: DUVAL JEAN MAURICE ROBERT
IPC: F42C19/07
Filed: 1981-10-27
Abstract: The electrical 'button' contacts (3) are formed in a flat distribution grid of work-hardened copper strips (4). The contacts can be formed by rivets which are then soldered either individually or together in an automatic process in which the contacts are held in position by an electromagnet. The grid is implanted in an insulating base (2) which can be fabricated from a polyethylene foam sheet which is layered with an adhesive which reacts with the heat. Both fixing of the contact pads and implantation in the insulator can be carried out on a flat bed to form a composite sheet in the form of a sector of a circle which is afterwards formed into a conical shell. The finished conical assembly is fixed to a solid metal cone (1). The insulating layer may be thinned by stripping off thin sheets of it prior to mounting it on the cone. The switch, used in warheads, operates on impact.

Title: Low temp. brazing gearbox components - with composite brazing metal to contain volatile zinc
Inventor: CARNECIALI JEAN-PIERRE
IPC: B23K35/02
Filed: 1981-11-17
Abstract: Two metal components e.g. a gear-box pinion and a dog clutch ring, are brazed together using a heating operation required in another stage of the production cycle, e.g. hardening. The brazing metal is selected to suit the relatively low temp. of this operation. It has a core e.g. of brass, protected by a covering film, e.g. of tin. The thickness of the film is between 0.01 and 0.10 that of the core. In one part, at least a groove or chamfer is provided to recover any overflow of brazing metal. Making use of a heating operation required for another purpose saves the energy normally required for brazing a composite part which would be virtually impossible to machine as one piece. Covering the base core of the brazing metal with tin prevents volatile fume escaping, and the resultant harmful effects upon the brazing process.

Title: Diesel engine cold starting method - involves increasing compression ratio and advancing timing at part loads
IPC: F02M59/26
Filed: 1981-12-07
Abstract: To aid cold starting in a highly-pressure-charged diesel engine the compression ratio is increased, while the max. cylinder pressure is kept below the permissible limit by controlled advance of the timing dependent on load, this being varied between the min. amount at full load and a normal figure at reduced and part-loads, typically between 0 and 20 deg. The compression ratio can be at least 11.6:1, and a combined fuel pump and injector can be provided for each cylinder, driven directly from the valve camshaft (12,13). The latter is driven from the crankshaft via an epicyclic gear train allowing its angular setting to be varied.

Title: Safety mechanism for ski boot fastening - includes pyrotechnic charge carried on flexible band to force latch open in response to electronically detected danger condition
Inventor: ROBINET JEAN
IPC: A63C9/08
Filed: 1982-01-06
Abstract: The mechanism includes a base attached to the ski, with a pivoting plate holding the sole of the boot in place. The plate has a spring biassed peg acting to hold it in place. A three-part lever cooperates with a stop and this plate such that if force is applied to one arm of the lever, the plate is rotated and the boot released. In response to dangerous conditions being detected by an electronic circuit, a charge may be electrically fired against a piston and rod. This drives the rod forward to act on the three part lever, thus releasing the latch holding the boot. On re-inserting the boot later, the mechanism is reset, and a new charge is automatically positioned ready for the next use.
