Title: Improvements in data processing systems
IPC: G06F15/08
Filed: 1959-11-30
Abstract: 923,859. Digital electric-calculating. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 30, 1959 [Nov. 29, 1958], No. 40618/59. Class 106 (1). The contents of a punched card are added or subtracted from a number held in a magnetic core memory 11, the orders of which correspond to columns of the card. All the 9's, 8's . . . punched on the card are added - in in successive machine cycles, one machine cycle being allotted to each digit. The 11-row of the card is sensed at a pre-read station to determine the sign of the number on the card. The 9-row is read and those brushes which sense a punch set cores of an input register 1. The input register is then dynamicized synchronously with the memory 11. A pulse issuing from register 1 causes circuit 4 (not described) to generate a biquinary output representing the digit 9, which is added in circuit 5 to the character stored to the corresponding order of memory 11. The sum is returned to the same order of the memory. The 8-row is then read into register 1 and all the 8's in the addend are added to the augend in memory, and so on, where the signs of the numbers necessitate a subtraction operation; the memory output is complemented before being applied to the adder. The dynamicizing pulses for memory and the register 1 are derived from the switching of cores in a shift register 31, the orders of which are patched together as required. Thus, columns of the card can be skipped. A card can contain two or more words occupying say columns 0 to 9 and 10 to 19 of the card. In this case the output of order 9 of the shift register is patched to an order of a " splitting- order " shift register 51, the output of that order being patched to order 10 of shift register 31. If there are only two words order 19 of shift register 31 is patched to a hub of register 51 which when energized signifies end of machine cycle. Each order of the register 51 consists of four cores as against the two cores of register 31 which control read-out and read-in of the memory. The four cores of register 51 control the sensing of overflow from the highest order of one word and the sensing of the sign of the next word. The sign, derived from the pre-read station, and the overflow, derived from adder 5, are stored in register 61. Depending on the operation, the sensing of overflow may lead to an automatic complementing operation. There is an overflow lamp. Read-out from memory takes place in the reverse manner. In each machine cycle cores are set in an output register 21 where the corresponding order of memory contains the digit being read-out in the machine cycle. The cores are reset in parallel and all the 9's, 8's ... are punched or printed simultaneously

Abstract: 1336815 Automatic exchange equipment SIEMENS AG 17 Sept 1971 [30 Sept 1970] 43389/71 Heading H4K A compressing arrangement in a PCM, TDM exchange employs code converters to bring all the conference subscriber signals into the same 12-bit code before adding all the signals which are then converted back into the original 8-bit code in coder reconverters and transmitted to the subscribers. The Specification is only concerned with a compressing arrangement for at least four subscribers and if a subscriber is absent a zero word is inserted in his place. The four wire system shown has input stores SE1- SE4 of which one is allocated to each of the four conference subscribers to store the signal in the respective time slot arriving on highways EMLI-N. These signals are simultaneously passed through code converters NL1-4, registers R1-4 and the two stages of binary adders so that the total signals can now be passed through reconverters LN1-4 and stored in respective ones of output stores SA1-4. The stores are read out on to the transmitting highways SMLI-N in the subscriber's time slot. The highway switches are controlled by rotary address stores UI-UN which control the incoming highway switches through decoders DEI-N and the outgoing highway switches through delay VtV and decoders DSI-N. The switches controlling the reading in and out of the input and output stores are controlled from rotary address store U4 in a similar manner to the highway switches. In a modification single code converters and reconverters can be used and are connected sequentially to the input stores and registers and the adders and output stores respectively. It is also proposed that the stores can be connected in sequence to a single line from the incoming and outgoing highways.
