Abstract

518,071. Photo-electric distant control apparatus. SOC. ANON. FIMI. July 15, 1938, No. 21011. Convention date, July 22, 1937. [Class 40 (iii)] An apparatus for producing at a distance rotating or translatory movements with simultaneous indication of the amplitude of the displacement comprises means for generating photoelectrically in conjunction with the relative displacement of a pointer and a scale a series of separate signal impulses of which both the number and the intensity are proportional to the displacement. As shown, a pointer 2 moving over a scale 1 carries a strip 3 with graded transparencies moving between a lamp 6 and a photo-electric cell 7.
