Title: Masking a semiconductor for ion implantation - avoiding use of strong acids for removal for window etching
IPC: H01L21/266
Filed: 1974-02-04
Abstract: Method of masking a semiconductor substrate for doping the semiconductor by ion implantation comprises depositing on the substrate surface at least one photosensitive material to a thickness sufficient to provide an obstacle for the passage of dopant ions, from which is removed a pattern of windows by photographic exposure representing the areas to be doped, doping the substrate then treating it with oxidising vapour or gas at low pressure activated by a high frequency electric field and stopping the operation when the layer of photosensitive material has been removed.

Title: Installation for rapid meat cooking - after selection, meat passes automatically between heating elements s for chosen amount of cooking
IPC: A47J37/04
Filed: 1974-06-14
Abstract: A display unit on top allows the meat to fall into the interior of the casing (1), onto a flap (18). This pivots down down and the meat drops into the gap between two endless chains (2, 3).

Title: Dispenser and register for restaurant waiters - waiter, drink type and volume pulse counters checked in register
IPC: G06C29/00
Filed: 1974-10-29
Abstract: Dispenser and register system for drinks etc., used by waiters and staff in cafes, restaurants, etc., is fitted with register keys which are depressed to feed in data on the waiter ordering the drinks, etc., type of drink, amount, price. The register trips a pulse transducer so as to emit a pulse count indicating the volume dispensed, and similarly a transducer for the type of drink, etc., and associated contacts for the volume counter for each type of drink. A comparator coupled to the register counter and the ordered-amount counter produces a blocking signal once these two counter readings coincide and a device connected to the blocking signal output from the comparator responds by preventing further dispensing when a blocking signal is present.

Title: Internal combustion engine exhaust gas purifier - with finely distributed secondary air in catalytic bed for afterburning
Inventor: PRIGENT MICHEL
IPC: F01N13/14
Filed: 1975-01-27
Abstract: The exhaust gases of an i.c. engine are catalytically purified by passing secondary air into the catalytic bed at a higher rate than is required for a complete oxidation of the unburnt matter. The air is introduced at points distributed throughout the bed. The mixture of exhaust gases and air has a ratio of oxidising to reducing components which rises from below stoichiometric at the inlet to above stoichiometric at the outlet of the catalytic bed. The delivery of secondary air is proportional to the engine speed and need not be altered when the load changes. At high loads, the NO percentage in the exhaust gases is high and the catalyst volume below the stoichiometric ratio automatically becomes smaller. During deceleration, greater quantities of unburnt matter will be issued and the volume above the stoichiometric ratio will be increased.
Patent FR-2263576-A1 (FR)
Title: Machine for making core and wire storage matrices - requires no extra support rollers for spiral
IPC: H01F41/08
Filed: 1975-02-28
Abstract: The machine threads magnetic cores onto flexible wires and has a mechanism which spaces the cores at regular intervals and it has a mechanism which forms the wire into a spiral having a pitch equal to the distance between adjacent cores. The diameter of the spiral lies between the outside and inside diameters of the core. Dimensioning the spiral in this way prevents the wire from sticking in the holes in the cores. A row of cores is fastened to a clamp or a substrate so that all the cores are in the same plane. One turn of the wire spiral goes through each core in turn.

Title: Skip lorry with remote operation - with skip clamped in adjustable hydraulic clamps on either lorry side
Inventor: GERGEN LEO HEINRICH
IPC: B60P1/48
Filed: 1975-07-10

Rams on the pendant arms secure the clamps and prevent the skip from falling off the lorry. The system dispenses with manually operated chain slings, with the whole skip operation, including dumping of its contents, controlled from inside the cab. The relative setting of the lifting arms takes account of bent and buckled skips.
Patent FR-2280842-A1 (FR)
IPC: F16K1/42
