Title: Object rim sensor with two light detectors for detection of position of objects
Inventor: SPOERL GEORG
IPC: G01D5/34
Filed: 1996-05-22
Abstract: A sensor system for detecting the position of an object edge by the change in a light beam falling on it consists of a light source (L)( from which a beam is directed towards two light-sensitive receivers (M,R). The first of these (M) measures the signal and thus identifies the position of the object. The second (R) acts as a reference and directs a signal back to a control unit (SR). This determines the intensity of further beams from the light source in relation to the radiation monitored by the detector. The control system ensures an adequate beam of light, not affected by fluctuations in the supply voltage, ambient light at the light barrier or discolouration or dirtying of the light source surface. It does not require expensive switching systems or optical components.

IPC: B03C1/247
Filed: 1996-08-29
Abstract: A particle separating device separates material to be sorted (1) into fractions of greater or lesser electrically conductive non-ferromagnetic particles (2, 3).
