Title: Motor vehicle with reduced fuel consumption - has pinion connected to either small capacity engine and electric motor or to both simultaneously
IPC: B60K6/383
Filed: 1978-09-11
Abstract: The motor vehicle is powered by a small cubic capacity engine to which a dynamo is connected to charge accumulators. The accumulators drive electric motors and the vehicle can be driven by either or both drive methods to reduce fuel consumption and pollution. The thermal engine of less than 50 cc. forms an engine block with a dynamo which is connected to a control box and battery. A pinion drives a wheel on a transmission shaft via a chain drive. The pinion is coupled to either or both the electric motor and thermal engine through a free wheel drive or centrifugal clutch respectively. The transmission shaft drives the vehicle wheels via a chain. Automatic switching disconnects the electric motor when its limit speed is reached.

Title: Level matching and luminance suppressing circuit for colour TV set - uses same reference voltage source for black level limiting and signal suppression during line flyback
Inventor: WOJERZ DANIEL
IPC: H04N5/18
Filed: 1978-11-21
Abstract: The circuit has an impedance-matching input stage, an inverting amplifier and an impedance-matching output stage. A level circuit holds the voltage of the black level to the level of a reference voltage. A suppressor suppresses the signal during line flyback. The level circuit and the suppressor use the same single reference voltage source. A sample comparator compares the output voltage from the circuit with the reference and its impedance is small during operation but high out of operation. During line flyback the impedance matching resistor of the luminance delay line is short circuited to protect it against interference.

Patent FR-2422227-A1 (FR)
IPC: G21C13/02
Filed: 1979-04-05
Abstract: The pressure vessel closure head (3) is clamped in a sealing fashion with its closure head flange (3.1) by means of prestressed expansion bolts (4) having nuts (4.2) and washers (U1) against the counter-flange (2.1) of a pressure vessel opening. In this arrangement, the washers (U1) are constructed as deformation members and are dimensioned to match the expansion bolts (4) in such a way that upon overshooting of a limiting internal pressure they give way to the closure head forces, under plastic deformation, by the distance DELTA lü in the pressing-on direction. The reduction in the overpressure takes place via the closure head sealing gap (5) which gapes correspondingly by an axial gap of DELTA lü, as far as a value at which the prestressing force of the bolts (4) remaining in the elastic range is sufficient to reseal the pressure vessel (1).

Title: Chromising of ferrous substrates in molten lead bath - using low chromium content to reduce roughness and porosity of coating
Inventor: RAUSCH JOHN J
IPC: C23C10/22
Filed: 1979-07-09
Abstract: A ferrous-based substrate is chromised by diffusion coating from a molten alloy bath consisting mainly of lead and contg. 0.85% chromium based on the weight of Pb, Pb being the only transfer agent in the bath and Cr pref. being the only diffusing element. Reduction of the Cr content of the bath results in reduced Cr concn. in the coating, giving improved ductility and malleability while still imparting adequate corrosion resistance and reducing costs. In addition, the risk of producing a rough, porous coating, which can occur during cooling of the bath due to Cr precipitating out of soluion, is reduced.
