Abstract: 1406470 Photo-electric apparatus INTERNATIONAL BUSINESS MACHINES CORP 20 Dec 1972 [4 Jan 1972] 58903/72 Heading G1A In an apparatus for monitoring irregularities on a periodically structured surface 8 in which a laser beam is scanned - from 2a to 2c - periodically across the surface to produce an interference pattern at a photo-cell assembly 9, the intensity of at least one order of interference is sensed. A laser beam is scanned across the surface 8, e.g. of a magnetic storage disc, by an oscillating mirror 5. For a disc of acceptable quality the machine markings on the disc will have a regular, periodic structure, Fig.2 (not shown) and the disc will hence act as a reflection grating. The assembly 9 is positioned such that the -1, 0, +1 orders of interference fall on photo-cells 12, 10, 11 respectively. A photo-cell 14 monitors scattered light, while photo-cell 13 receives the ¢ order of interference. For a regular surface structure the output from photo-cell 13 will be steady and relatively low, Fig.4, left (not shown). However, irregularities in the machine cut, Fig.3 (not shown) will produce a varying, relatively high output from photo-cell 13, Fig.4 right. The scattered light level output from photo-cell 14 will also be greater in the latter case. The entire disc surface is scanned either by rotating the disc or by rotating the optical system about the disc.

Title: Cct preventing faulty synchronising of incoming generator - measures instantaneous difference between generator and system voltages
IPC: H02H7/22
Filed: 1975-06-30
Abstract: The object is to prevent closure of the generator (G) circuit breaker (S) if the generator and transformer (Tr) voltages are grossly out of phase, or if a short circuit exists on one side. Proportional signals of generator (UG) and transformer (UT) voltage are fed to a voltage sensitive relay (ES) which picks up at a certain threshhold value. Thus if a large phase difference exists between the two voltages a large instaneous voltage appears at the relay which responds and opens contacts (1, 2) in the circuit breaker closing circuit. Any closing signal coming from the remote close switch (ESB) is thus interrupted and the breaker remains open.
