Patent DE-19532278-A1 (DE)
Inventor: BERGER HEINZ DIPL ING
IPC: C23G1/10
Filed: 1995-09-01
Abstract: A strip of stainless, ferritic or austenitic steel or a titanium alloy produced by hot-rolling or casting is uncoiled and (if required) mechanically descaled. This is followed by chemical and/or electrochemical preliminary pickling, and concluded by cold-rolling to finish dimensions, with possible degreasing, annealing, finish-pickling, passivation, finishing and stretch-straightening. The method is characterised by the fact that preliminary pickling takes place with a solution containing hydrochloric, sulphuric and/or nitric acid.

Title: Procedure for selective opening of circuit breakers in low voltage plant
Inventor: SCHULZE JUERGEN DIPL ING
IPC: H02H7/26
Filed: 1996-11-07
Abstract: A procedure for the selective clearance for the opening of a circuit breaker in a low voltage plant in case of overload, especially for short- circuit currents, has a conducting system used which has something to transmit information between the circuit breakers and stations (1) assigned to them and something to recognise the energy flow based on the actual switching state of the breakers. Each breaker that detects an overload signals this to the breaker that is recognised by the system at the time as the overriding breaker and the opening is cleared by the system of only the breaker which receives no signal of overload from a subordinate breaker.
