Abstract: 858,212. Digital electric calculating apparatus. SPERRY RAND CORPORATION. May 30, 1957, No. 17161/57. Class 106 (1). In a system for transferring data from a transmitter to a receiver a checking circuit is included in the transmission path and is so arranged that when an error is detected the data is not sent to the receiver but is sent to an amplifier from where it is resubmitted to the checking circuit. As described, data is transmitted from a source 11, Fig. 1, via a gate 12, a parity checking device 13 (as described in Specification 749,836 which is referred to) and a gate 14 to a receiver 15. When an error is detected by the parity checker 13, gates 12 and 14 are closed and the data circulates from the parity checker via a gate 18, a delay 19, an amplifier 21 (referred to as a mutator) and a counter 22, back to. the input of the parity checker. If an error is still present the gain of the amplifier 21 is raised and the data makes a further cycle. If an error is still present, further cycles are made until five in all, counted by the counter 22, have been made. If an error is then still present, a warning is given to the operator. If, however, after one or more cycles in the loop an error is not detected, the data passes out via gate 14 to the receiver in the normal way.
