Title: Composite transistor circuit
IPC: H03F3/30
Filed: 1975-01-11
Abstract: A circuit exhibiting the characteristics of a transistor suited for use in a quasi-complementary push-pull amplifier uses input and output transistors of the same conductivity type. The "base" electrode of the composite transistor is at the emitter electrode of the input transistor, operated as a common-base amplifier. The collector electrode of the input transistor is coupled by a current mirror amplifier to the base electrode of the output transistor. The "emitter" electrode of the composite transistor is at the joined base electrode of the input transistor and the collector electrode of the output transistor. The "collector" electrode of the composite transistor is at the emitter electrode of the output transistor. The current gain of the composite transistor can be made to be equal to that of the output transistor, although the apparent conductivity type of the composite device is opposite to that of the input and the output transistors.

Title: Fluid counter
IPC: G01F1/06
Filed: 1976-12-17
Abstract: The present invention relates to a fluid counter, and more particularly to a liquid counter. The fluid counter includes a rotor which is equipped with a shaft. One end of the shaft terminates at a point which is used solely for low flow rates. The other end of the shaft terminates at a flattened sturdy surface which is used solely for high flow rates. Each of the ends of the shaft are able to cooperate with corresponding stop members. The distance between the ends of the shaft is slightly smaller than the distance between the stop members. In this manner, the two ends of the shaft cannot simultaneously cooperate with their respective stop member. Thus, the pointed end of the rotor's shaft is put into operation by a low fluid flow rate and the flattened end by a high fluid flow rate.

Title: Facing sheet for laminating onto support esp. furniture - is coated with plasticiser and heated before bending around curved edges
IPC: B29C63/04
Filed: 1979-05-23
Abstract: A method of gluing a duroplastic facing sheet onto the surface of a support which possesses rounded edges is as follows. The facing sheet is cut to the required dimensions to cover round the rounded edges and the projecting portion of the sheet is coated with a plasticiser to soften it before the sheet is bent around the edge.
