Abstract: 1,017,716. Photo-electric level control. RANCO Inc. May 1, 1964 [May 9, 1963], No. 18319/64. Heading G1A. [Also in Division G3] Apparatus for controlling the height of a heap of particulate material comprises a light source directing a beam of light across the heap to a detector and means responsive to an increase of light on the detector owing to a decrease in height of the heap to cause material to be added to the heap and the intensity of the light source to be increased. A heap 13 of ice cubes produced by an ice making machine is monitored by a beam of light 23 from a lamp 20 to a semi-conductor light-controlled,rectifier 24. The lamp is fed at half power by current from the winding 36/38 of transformer secondary 37 half wave rectified by a diode 45. When the heap falls to a lower control level 24 conducts. This operates a time delay relay 56 to start the ice making machine, and feeds the other half wave via diode 60 to the lamp 20 which thus operates a full power. The result of this is that the heap must rise considerably to a higher control level before the ice making machine is switched off. The control levels are set by adjusting the resistor 42.
