Patent ES-350516-A1 (ES)
Title: Electromagnetically Controlled Magnetically-Retained Relay.
IPC: H01H51/01
Filed: 1968-02-15
Abstract: A polarized bistable relay has two C-shaped core 15, 16 members arranged in parallel planes with a permanent magnet between them and windings 41a, 41b, 42a, 42b, on the core for momentary energization to effect movement of an armature 18 between poles 15a, 16a and 15b, 16b of the cores. The armature comprises magnetic steel straps 18a, 18b insulated at 34, 35 and supported on three cantilever contact springs 20 (Fig. 9, not shown) which co-operate with fixed contacts 27, 28. The permanent magnet flux retains the armature in the position to which it was last moved and momentary reverse energization of the windings is necessary to move the armature to its other stable position. Fig. 8 is a diagrammatic representation of the magnetic circuit in one plane. The armature may be mounted on pivoted arms rather than cantilever springs (Fig. 11, not shown) and only one coil may be provided on each C-shaped core (Fig. 12, not shown).

Title: Error logging in semiconductor storage units
IPC: G06F12/16
Filed: 1975-07-04
Abstract: A maintenance procedure comprising a method of and an apparatus for storing information identifying the location of one or more defective bits, i.e., a defective memory element, a defective storage device or a failure, in a single-error-correcting semiconductor main storage unit (MSU) comprised of a plurality of large scale integrated (LSI) bit planes. The method utilizes an error logging store (ELS) comprised of 128 word-group-associated memory registers, each memory register storing 1 tag bit and 6 syndrome bits. Upon determination of a single bit error during the readout of a word from the MSU, stored in the ELS are: (1) a tag bit that when set signifies that a defective bit has been determined to be in the one associated word group and, (2) a group of 6 syndrome bits that identifies that one of the 45, 1024-bit planes of the one associated word group that contains the defective bit. A defective device counter (DDC) counts the set tag bits in the ELS and is utilized by the machine operator to schedule preventative maintenance of the MSU by replacing the defective bit planes. By statistically determining the number of allowable failures, i.e., the number of correctable failures that may occur before the expected occurrence of a noncorrectable double bit error, preventative maintenance may be scheduled only as required by the particular MSU.
