Abstract

1,100,462. Magnetic core matrix stores. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. 17 Sept., 1964 [2 Oct., 1963], No. 39304/67. Divided out of 1,100,461. Heading G4C. [Also in Division H3] The description is wholly contained in the parent Specification but the claim is directed to a pre-operate disturb pulse to restore cores of a magnetic core matrix store from a minor to the major hysteresis loop, said pulse occurring after the initiation of a storage access cycle but before a core or cores are actually accessed. This feature is described in the abridgment of the parent Specification.
