Abstract
849,556. Photo-electric readers. COMMUNICATIONS PATENTS Ltd. Sept. 20, 1956, No. 28747/56. Class 40(3). [Also in Groups XXXVIII and XL(c)] The reading of a perforated tape coded according to the Cartesian co-ordinates of an object in a radar simulator is carried out by photo-cells 19-23 whose amplified outputs energize relays 29-33 to control the stepping of uni-selectors 34-36 associated with co-ordinate potentiometers 46-48 (see Group XL(c) ). Specification 814,392 is referred to.
