Abstract

891,895. Timed control of electric circuits. COBEN, C. A. June 9, 1960 [June 19, 1959], No. 21191/59. Class 118. A clock mechanism drives a chart element at a constant speed, and marks constituted by deformations in the chart element operate a sensing device which causes generation of a signal, the apparatus including a marker for applying the marks to the chart element at positions corresponding to predetermined points in the time cycle of the clock mechanism. As shown, a synchronous electric motor 1 drives clock hands 3 and, through a sprocket 6, an endless band 7 having notches 13 in one edge. These notches cause a sensing arm 16 to operate a microswitch 14 at predetermined times. The notches 13 may be made by a punch 11 which engages the band 7 at the same point as the sensing arm 16.
