Patent FR-2299519-A1 (FR)
Title: Charge of projectile propellant with combustion inhibitor - covering propellant surfaces in part and destroyed after time delay
Inventor: DOIN BERNARD
IPC: F02K9/14
Filed: 1975-01-31
Abstract: A pyrotechnical charge has at least one zone of its gas generating surface coated with a material which inhibits combustion and is destroyed by the thermodynamic conditions created during the initial stages of combustion. The inhibiting cladding may be destroyed at the end of a combustion period which is less than 50% of the total duration of combustion, and it covers an area of the charge less than 60% of the gas generating surface. The coating is relatively thin and is broken down by the thermodynamic conditions prevailing in its proximity after ignition. It may however also include an inhibitant which is fully capable of withstanding the ambient thermodynamic conditions after ignition, is a good conductor of heat, and is sufficiently thin to be destroyed when the propellant beneath it is ignited. Prevents an initial excess of gas pressure and premature ignition of the mass of the charge. The initial combustion surface is limited so that the volume of gas generated is restricted temporarily without the subsequent course of the combustion being affected particularly. A high coefficient of loading can thus be achieved.

Patent FR-2283484-A1 (FR)
Title: Transistor current source - independent of temperature and supply voltage for logic circuit integration
IPC: G05F3/22
Filed: 1975-08-26
Abstract: In this constant current circuit, the normal amplifier emitter resistance is replaced by a transistor (T11) or multiple transistors in parallel (T1). The base of this transistor is connected to an emitter follower (T2) which is, in turn, coupled to the collector of a sensing transistor whose base is at the junction of two resistance (R5, R6) acting as a potential divider across the supply (Uo, Uv). The combined resistance of these two equals the ratio of the collector and base resistors of the sensing transistor and the emitter follower current is lower than that in the emitter replacement transistor. This provides a circuit that, in circuit integration, gives a source current independent of temperature and supply voltage.
Patent FR-2283315-A1 (FR)
Title: Turbo charger for vehicle I.C. engines - has relief valve electrically controlled from pressure differential and surge line comparator
IPC: F02B37/16
Filed: 1975-08-29
Abstract: An internal combustion engine (10) is supplied by a turbocharger (11) on a shaft (13) driven by an exhaust gas turbine. There is a flow meter (19) on the inlet of the turbocharger and there are pressure detectors (22, 23) on the inlet and discharge. The signals from all three detectors are fed into a comparator (18) which contains base data corresponding to the surge line of the turbocharger. The output of the comparator controls a solenoid valve (16) in a bypass (15) from the discharge to the inlet of the turbocharger. The valve is opened when the flow drops to the surge points to prevent surging occuring. The system responds more rapidly to a reopening of the throttle than a simple pressure relief valve on the discharge.

Title: Electric blanket fabric of needle bonded nonwovens - with spot weld patterns formed sonically or supersonically
IPC: B29C65/08
Filed: 1976-03-19
Abstract: The fabric of an electric blanket enclosing the heating wires is formed from first and second needle-bonded fabrics. These contain textile fibres and are laid one upon the other, one of the two fabrics at least having embodied in it a layer of flat yarns extending in one direction. A component which can be melted by heat is also incorporated in one of the fabrics, and the fabrics are fastened together by a pattern of small separate spot welds distributed over the whole area of the blanket. The patterns define series of channels for holding the wires between the two fabrics, and they are applied transversely to the direction of the flat yarns in the yarn layer. The spot welds do not involve more than 50% of the flat yarns, whilst any overlapping of the welds is avoided. To produce the patter of spot welds, the first and second needle bonded fabrics, one contg. a component which can be melted by heat and one contg. a number of flat yarns lying in the direction of one plane of the needle bonded fabrics, are passed through a sonic or ultrasonic welding station. The fabrics are supported by a moving surface such as a drum, on which a pattern of small separate anvils works with the sonic or ultrasonic energy to bring about the welds.
