Abstract

970,231. Machinery guards. SPERRY RAND CORPORATION. Jan. 1, 1963 [Jan. 9, 1962], No. 62/63. Heading F2J. [Also in Division B8] Obstruction of the guarded area (Fig. 1, not shown) of a conveyer results in a signal of decreased strength being transmitted by photoconductive cells PC1 and 2 (in series with NPN transistor stage T1) to parallel PNP transistor stages T2, T3. This results in the release of relays A and B. This releases a relay C by opening of contacts A2, B2 in circuit C4, C, B2, A2, S1, C2. Contacts C3 thus open to release a relay Cx which controls the conveyer (not shown). Contacts C1 isolate lamps LP1, LP2 which normally activate the cells PC1 and 2 respectively. To reset the system it is necessary to press push button PB and close switch KS. Failure of almost any component of the system will cause the system to " fail safe."
