    Abstract: 936,331. Digital electric calculating. INTERNATIONAL BUSINESS MACHINES CORPORATION. Jan. 4, 1960, No. 268/60. Class 106 (1). An operation is divided into an instruction cycle, in which the computer controls are set up, and a variable number of execute cycles in which data specified by the instruction is operated on. Each execute cycle is divided into a read time in which a data character can be read from a store and a write time in which a data character can be written into a store. The invention provides means stated to be conventional in form whereby data read from a store location during a read time is written back in that location after processing during the write time of the succeeding execute cycle, reading from the succeeding store location having taken place during the intervening read time. The operands are taken from core memory 1.10 and storage 1.12. A location in memory 1.10 comprises five binary-coded decimal characters which are read out in parallel to buffer register 1.16. From the buffer register single characters are read out to CR-1, 1.18. A location in storage 1.12 comprises a single character which from buffer register 1.34 is read to CR-2, 1.36. The characters in CR-1, CR-2 are operated on in arithmetic unit 1.14 and the result placed in register 1.52, from which it may be returned either to memory or storage. Storage 1.12 is a five character register into which an operand is read preparatory to an arithmetic operation.

    Abstract: 993,113. Statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. April 23, 1964 [May 16, 1963], No. 16778/64. Heading G4M. A record card, Fig. 1, has zone 14a-14c in which the characters 0-9 are printed in red, and further zones 12a-12c in which groups of code marks corresponding to these characters are printed in black, the code illustrated being binarycoded decimal with an even parity check bit. Information is recorded on the card, e.g. by a meter reader, by making a black mark over the appropriate characters in zones 14a-14c.. The card is sensed by passing it beneath a group of ten photo-cells which are insensitive to red light. As the black line Z1 passes the photocells, AND gate 47, Fig. 5, produces a pulse to trigger a timing circuit 50, and a synchronizing pulse is transmitted to remote data-processing equipment through OR gate 69. Trigger SS1 enables the AND gates 61 in a set of latches 60-0 to 60-9 so that when the black mark in zone 14a is sensed the corresponding trigger 63 is set to enable AND gate 65, and immediately afterwards AND gates 67 are enabled by trigger SS3. Pulses derived from the code marks in zone 12a corresponding to selected character are then passed by AND gate 67 in the appropriate latch 60 and are transmitted to the data-processing equipment. Finally, trigger SS2 resets the set trigger 63 and the system is ready to start a fresh cycle when the next black line Z1 is sensed. The card shown in Fig. 2 is marked in zones 34 to indicate alphabetic or numeric characters. In sensing such a card, relay M-1, Fig. 5 is energized to enable gates 67 during the complete sensing cycle. When the mark in zone 34 is sensed the corresponding trigger 63 is set as before, but the pulse derived from this mark is now also passed through gates 65, 67 and forms part of the code group transmitted.
