Abstract
804,614. Photo-electric impulse generators. BERLINER MASCHINENBAU A.G. VORM. L. SCHWARTZKOPFF. May 30,1956 [June 6, 1955], No. 16705/56. Class 40 (3). [Also in Groups IX and XXXVII] A switching device for the automatic control of the feed mechanism of a fancy doubler has a rotary control member with a number of adjustable parts and an electric switch, whereby each switching combination can be adjusted without any changing of parts, the switch having an oscillating to-and-fro motion imparted to it in the direction of motion of the control member. .In the photo-electric embodiment (see Figs. 1 and 2) adjustable diaphragms 4 in rotating hollow cylinder 1 can be opened, see for example a, b, in the path of light from lamp 7 through slotted screen 8 to photo-cell 10. Member 6 supports the lamp, screen and photo-cell casing 9 and can be oscillated about cylinder driving shaft 3 by eccentric cam 13 and spring 15. In the other embodiment (see Group XXXVII) a micro-switch is operated mechanically by a cylinder carrying adjustable tongues. Several devices may be mounted on one shaft.
