Title: Low system voltage surge diverter - has fuse for interrupting fault current to earth after diverter operation
Inventor: WESSING EGON DIPL ING
IPC: H01T1/14
Filed: 1980-12-24
Abstract: The proposed design of low voltage surge diverter is applicable to the protection of electrical supplies entering office buildings and private houses. It provides a controlled and relatively low spark over voltage, and safe interruption of the earth fault current which results if the spark over device becomes short circuited. The spark over, or discharge, device is a hermetically sealed unit (17), for example a ceramic housing with a gap between internal electrodes, and filled with an inert gas, typically argon. Being largely unaffected by ambient conditions it can be designed to operate at a sufficiently low voltage to give adequate protection to sensitive apparatus. A circuit interruptor (6) is connected in series between the live terminal (3) and earth (2). It comprises a spring loaded plunger (8,9) soldered (13) to an electrode (12) on one side of a varistor (14) which is electrically in series with the other components. A fuse (20) is connected across the plunger. If an earth fault current becomes established the varistor heats the electrode and the solder melts. The spring (9) then opens the circuit by throwing off the plunger (6). During this time the current is carried by the fuse which then also melts. By this means there is no uncontrolled arc when the spring and plunger circuit opens.

Patent DE-3134398-A1 (DE)
Title: Die-casting process and an apparatus for carrying out this process
Inventor: HEILOS HANS CHRISTOPH
IPC: B22D18/00
Filed: 1981-08-31
Abstract: A description is given of a process for the production of die castings and of an apparatus for carrying out this process. In this new process, the metering of the melt for the component to be cast and the production of the pressure for the injection of this melt are temporally separated. The invention provides a die unit which is a sealed unit which already contains the melt and can be handled separately since it is provided with high-grade thermal insulation with respect to the outside. The entire die unit is then put under pressure and the melt is thereby forced into the die for the component. The die unit is preferably provided with ceramic constructional elements which, by virtue of their high thermal stability, their high, variable heat capacity and their very low thermal conductivity, allow the casting of extremely high-melting materials. By means of the process and the apparatus according to the invention, it is possible to cast different extremely high-melting materials in direct succession in an economical manner without retooling and it is, moreover, possible to vary within wide limits the shape of the die casting to be cast in successive shots.
