Title: Interpolation network for discrete displacement measurement transducer - uses light source moving along axis w.r.t. photocell array producing outputs phase-shifted by discrete amounts
Inventor: FISCHER VOLKMAR DIPL ING
IPC: G01D5/244
Filed: 1977-05-11
Abstract: A simple discrete displacement transducer logic interpolator produces, typically, twenty interpolated intervals in each primary interval, using only simple squaring and gating networks. The interpolator can be applied to an array of photocells arranged along an axis and subjected to an illumination of intensity varying sinusoidally w.r.t distance along that axis. The illuminating source along the axis concerned w.r.t the photocell array, producing photocell outputs shifted in phase w.r.t each other by fixed discrete amounts, depending on the velocity of the light source. The photocell outputs are fed in pairs to an array of linear comparator circuits and the square wave outputs of these are taken to an arran of AND gates. The outputs of these are in turn, fed to two OR gates to produce two square waveforms at ninety, one delayed on the other by a quarter period and both running at five times the original photocell output frequency.

Title: Cutting machine hazardous area protective cabinet - uses generator feeding light transmitters projecting light beams to receivers limiting specific area
Inventor: SCHNEIDER HANS
IPC: H03K17/94
Filed: 1977-12-01
Abstract: A four-channel light cabinet has four transmitters which work in conjunction with four reeivers, forming four beam paths. These are arranged as so to limit a specific machine area so that at least one beam path is broken if an operator encroaches on that area. An RC generator would produce a rectangular power of 1kHz with a probe ratio of 1:1. This generator would feed all transmitters synchronously with operating impulses, so that they produce light impulses with the frequency, phase position and probe ratio of the generator impulse. Gallium-arsenid diodes form the transmitters, being capable of working in the infra-red sphere with favourable influence on the suppression of exterior light influences.

Title: Light screens, esp. for protective spectacles used in welding - where two side-shaped Moire grids are used to obtain sharp image
Inventor: LANGENBECK PETER DR
IPC: A61F9/06
