Abstract
Abstract 1,008,054. Record carrier feed. NATIONAL CASH REGISTER CO. April 17, 1964 [May 13, 1963], No. 15943/64. Heading G5R. A record carrier feeding system moves the record carrier in either direction past a transducer in response to forward or reverse control signals applied at F or B respectively, a bistable arrangement 50 stores the previous control signal and if a control signal is the same as the previous control signal -it is passed through AND gates 44 or 42 to the forward or reverse drives without delay, but if it is opposite to the previous control signal it is delayed until the bi-stable arrangement 50 has been switched, and switching of the bi-stable arrangement is delayed by a monostable arrangement 24. In this way abrupt reversal, with consequent damage, is avoided.
