Title: Interconnected thyristors voltage and current control - uses saturable reactors mounted on common magnetic core
Inventor: BUESCH GUNNAR DIPL ING
IPC: H02M1/088

Title: Scanning system for measuring precision components - uses photocell groups at right angles with second set operated automatically by first set
Inventor: ARMBRUSTER KARL DIPL ING
IPC: H04N3/30
Filed: 1979-10-04
Abstract: The component is scanned in two directions at right angles. The scanner camera incorporates two lines of diodes at right angles to scan the component in the X direction and in the Y direction. As the component is moved past the camera, one edge of the component causes the grey value to alter, so as to vary the charge on the photo cells along one line. The other line of photo cells is then operated automatically to scan in the other direction at right angles. The analog image signals are converted to digital signals are then processed by a computer for storage or evaluation. The device which automatically operates the second set of scanning diodes is a logic device.
