Abstract

730,549. Photo-electric sorting apparatus. BAIGENT, G. M. July 6, 1953 [April 4, 1952], No. 8727/62. Class 40 (3). In photo-electric apparatus for sorting articles according to their colour or surface imperfections a photo-multiplier tube replaces the usual photo-electric cell thus making a high-gain amplifier unnecessary. The tube may be employed in the apparatus described in Specifications 712,113 and 730,177, in which articles to be sorted fall through a tube and are " viewed " through a number of apertures against a uniformly illuminated background. A circuit operated from the multiplier anode may be so arranged that increase or decrease of light above or below a certain value may produce a pulse to operate an electromagnetically-controlled sorting device which may be either mechanical or pneumatic.
