Abstract
887,539. Magnetic record apparatus; programme control systems. TELEFUNKEN G.m.b.H. Feb. 9, 1960 [Feb. 13, 1959], No. 4533/60. Drawings to Specification. Classes 38 (6) and 40 (2). In a machine control system employing a record tape bearing control pulses, each of which is detected by a first magnetic head to effect a switching causing the reduction of speed of the machine, and then detected by a second head to stop the machine, the amplifiers associated with each head have a frequency gain characteristic such that the gain decreases with frequency whereby the output voltage is maintained by whichever head and amplifier is in operation when the machine has been switched to the lower speed.
