Title: Measurement method for leakage current of electrolytic capacitor - charges capacitor in short time period, integrates current over subsequent period from 500 to 1000 m.s. and then disconnects voltage source
Inventor: BENZ OTTO ING GRAD
IPC: H01G9/00
Filed: 1979-02-01
Abstract: An electrolytic capacitor can be charged in a short time by a constant current until it reaches a specified potential and is then held at that potential by a voltage source. The leakage current can then be measured after a very short time by integrating the current over a specified time. The method is much faster than previous techniques and can easily be automated. A typical measurement cycle would be to charge the capacitor in 300 ms or less and to integrate the current between 500 and 1000 ms. The voltage source can then be disconnected and the discharge time constant measured between 2000 and 2500 ms before forceably discharging the capacitor by 3000 ms.

Title: Cold deformation of butt welded joints in wires - restores nominal wire diameter without loss of mechanical strength
Inventor: KATZSCHNER WOLFGANG DR
IPC: H01R43/042
Filed: 1979-07-13
Abstract: The application is typically to the mfr. of cable cores or insulated wires. Where a wire has to be jointed in order to achieve the required length this is done by butt welding. The result of the welding operation is that at the joint the wire diameter is larger than the nominal wire size. To eliminate this swelling without reducing mechanical strength a cold forming process is applied to reduce the diameter at least to that of tbe original wire. The forming removes no material and at the same time gives some work hardening. The cold forming, at least for wires, may be carried out with a hand operated swaging tool having a die of the required wire dimensions. The process reduces the risk of fractures at the weld point during subsequent handling operations.

Title: Power plant using refrigerant working medium - has highly pressurised vapour refrigerant passed through turbine then cooled in condenser
Inventor: CHIH-KANG SHAO
IPC: F01K25/08
Filed: 1979-11-17
Abstract: The refrigerant is used to drive a turbine operating a power generator. A source of refrigerant is provided as a compressed liquid phase. The source is heated by immersion in a tank of relatively hot liquid to provide high pressure vaporised refrigerant. The vaporised refrigerant is passed through the turbine to drive it. Passage of the refrigerant through the turbine reduces the pressure of the refrigerant. The reduced pressure vaporised refrigerant is exhausted from the turbine and then cooled. The cooled vaporised refrigerant is compressed in a heat pump having supplies of hot and cold liquid to convert the refrigerant to its liquid phase at a pressure higher than the source pressure. The compressed liquid refrigerant is returned to the source. The supply of cold liquid is derived from a condenser circuit through which the cold liquid flows in heat transfer relation with liquid used for cooling the reduced pressure refrigerant and the supply of hot liquid is derived from the tank.
