Patent DE-2343413-A1 (DE)
Title: Supervisory system for indicating operation of parallel fuses - uses two relays discriminating between first and subsequent operations
Inventor: KAMP GUENTER
IPC: H02H3/04
Filed: 1973-08-29
Abstract: The equipment is typically for use in supervising the state of fuses in parallel paths of rectifiers, and is intended to indicate the first fuse operation and then one further operation, for example when the equipment is at risk due to several fuses having blown. The initial indication employs a differential relay. The additional relay is held on by currents flowing in the parallel supervisory branches, one for each fuse, fed from a winding on an auxiliary transformer. The bias of the relay is such that the current in its coil only drops below the holding value when a certain predetermined number of parallel paths have opened in the main circuit.

Title: Measurement of mean value of cyclic variable - involves sampling at same point of several successive cycles and averaging
Inventor: KOCHANOWSKI HANS ALFRED DIPL I
IPC: G01D1/02
Filed: 1974-02-22
Abstract: The method may be used for the electronic measurement of quantities and derivation of mean values in processes of a similar repetitive nature, which do not repeat with exact quality each cycle, such as pressure, temperature, torque, etc., using linear measuring transducers. A measurement is made at a corresponding points of a number of successive periods; it is expressed in digital form, and is fed into a digital processor. The measurements are integrated and the result is divided by the number of measurements made to derive the mean value at that point in the cycle. The apparatus is esp. of use when the successive signals are nominally the same, quantity to be measured being constant or changing only slowly. The method has the effect of filtering out noise.
