Title: Water powered rotary engine - with pistons tangential to rotor and transmitting force to rollers via linkages and gears
IPC: F03B17/00
Filed: 1974-11-18
Abstract: The engine rotor rotates inside the housing and is provided with four equally spaced cylinders with their axes tangential to the rotor. Each cylinder is provided with a piston on which the water pressure acts. An additional force is exerted by a spring and a bar made from a material having a high coefficient of thermal expansion.

Title: Material process chamber seal - has a convex wall with inlet covered by a continuous flexible belting
IPC: F16J15/16
Filed: 1974-12-17
Abstract: An appts. is claimed to seal a process chamber, where web or sheet material is passed into a chamber where the pressure is different from ambient pressures or conditions, with one chamber wall given a curved convex profile and provided with a slit for the material to be processed to pass into the chamber. The sealing is effected by a flexible membrane which is pressed against the convex wall surface overlapping the dimensions of the inlet slit. The design gives a sealing system whch effectively separates the chamber's interior from the ambient atmos. prevents any leakage, and which does not require any lubricant which would attract dust and dirt, in a simply manufactured and economic-running unit.

Title: Extracting or inserting irradiation capsule in fuel assembly - partic. for experimental irradiations in fast neutron nuclear reactor
IPC: G21C19/105
Filed: 1975-08-05
Abstract: An appts. for extracting an irradiation capsule from or inserting it in, a combustible assembly incorporates a tubular body in which are a central tube, an operating tube and a mechanical system for moving vertically the tubular body and the central tube. The tubular body can be brought to rest on the combustible assembly. The central tube has at its end a part which can be brought into contact with the head of the capsule and carries grips. The operating tube brings about the freeing of the capsule in the assembly. It can be joined, by a system of balls fitting into grooves, to the body when the capsule is totally in the assembly or to the central tube when the capsule is held by the grips. The mechanical system consists of a manually controlled screw-nut system, operated by a handle turning the nut. The nut cannot move vertically so that its rotation causes the screw to rise or fall. The screw is connected to the central tube and the system can bring about successive vertical movements, in opposite senses, of the body and the central tube when the central tube is in contact with the capsule, for insertion, and when the tubular body rests on the assembly, for extraction. The operating tube can follow those movements and open or close the grips and free the capsule. The appts. incorporates an electrical detector which shows when the tubular body comes to rest in the assembly and an indicator which shows the position of the capsule in the assembly.

Filed: 1976-09-06
Abstract: Monolithic semiconductor device comprises >=2 transistors forming a Darlington amplifier. It is made from a heavily doped substrate of first conductivity type covered with a first epitaxial layer of weakly doped semiconductor of the same conductivity type, and a second epitaxial layer of weakly doped opposite conductivity type. The base regions are portions of the second layer while the emitter regions extend from the surface of the substrate. The substrate and the first layer form the common collector electrode for the two transistors.

Title: Monolithic arrangement of two complementary transistors - improves saturation voltage of multi-epitaxial transistor structures of two opposite types
Inventor: BONIS MAURICE
IPC: H01L27/082
Filed: 1976-12-29
Abstract: The monolithic semiconductor arrangement includes at least two transistors of opposite type. They are formed on a plane substrate of a first type of conductivity covered by a first layer of opposite type conductivity. The substrate forms the collector of the first transistor. The base of the first transistor and the collector of the second transistor are formed from portions of the first layer. The emitter of the first and the base of the second transistor are formed from portions of a second layer of the first conductivity type situated on the first layer. The coplaner parts of the interface between the two layers forms the emitter base junction of the first transistor and base collector of the second transistor. The junctions are separated by a highly doped zone of opposite type conductivity. This zone extends from the surface of the semiconductor up to a highly doped buried plane layer of the same type of opposite conductivity. The buried layer is localised according to the same geometry as the base collector junction of the second transistor and is situated at the level of the first layer.
