619,524. Detecting faults in rectifiers. STANDARD TELEPHONES & CABLES, Ltd. June 6, 1946, No. 17258. Convention date, July 21, 1945. Drawings to Specification. [Class 37] [Also in Group XXX] A machine for testing dry contact rectifiers comprises a hopper in which the rectifiers are initially stored and from which they are fed to a first testing point where a circuit is completed through the rectifier so that if its forward resistance is too high a relay is actuated to remove it into a first reject bin; if the forward resistance is not too high, the rectifier is passed to a second testing point where a relay is actuated to direct it into a second reject bin if the backward resistance is too low, but if the backward resistance is not too low, the rectifier passes to a " pass " bin. |
