US Patent:

45175004, May 14, 1985

Filed:

Nov 16, 1983

Appl. No.:

6/552597

Inventors:

John D. Gotal - Bristol RI
Junius D. Scott - Homer City PA

Assignee:

FMC Corporation - Chicago IL

International Classification:

H02K 3300

US Classification:

318130

Abstract:

A synchronized subharmonic controller for a dual coil electromagnetic vibrator, which derives both power and timing from a single phase AC line, having a trigger circuit which operates the coils at one-third the power line frequency. A timing circuit is optically coupled to alternately fire a pair of oppositely-directed SCR's with each SCR connecting one of the coils across the AC line. The optical coupling reduces feedback from the coil circuitry to the timing circuit. A pair of capacitors supply additional power to operate the coils and to reduce the peak values of current supplied by the power line.

US Classification:

198395

Abstract:

A programmable parts reorienter and feeder utilizing a fiber-optic array in a sensing head to determine an initial orientation of a part passing through a parts handling unit. The sensing head is coupled to a microprocessor that has been programmed to recognize properly oriented as well as misoriented parts. After determining the initial orientation of the part the microprocessor will direct a reorienter device to either pass the part in the first orientation, orient the part to a preferred orientation or, in some cases, reject the part.
