Patent GB-673683-A (GB)
Title: Improvements in or relating to record card controlled accounting machines
Filed: 1949-06-30
Abstract: 673,683. Statistical apparatus. BRITISH TABULATING MACHINE CO., Ltd., GROSS, L., and BAILEY, E. June 29, 1950 [June 30, 1949], No. 17316/49. Class 106 (i). In order to reduce the number of machine cycles necessary to the preparation of an account, cards bearing the name, address, and town are sensed and printed at the end of the run of detail cards concurrently with the " total" printing cycles. The invention is applicable to a tabulator of the type described in Specification 422,135 to which some additional relays and associated circuits are added. In this type of machine it is usual to insert four separate address cards, each card bearing one line of the address, ahead of the detail cards recording the individual items of the account, and after printing the address, and costing the detail items, the machine prints the totals of debit and credit items, subtracts credit from debit, 'prints the balance, and resets the counters. Four cycles of machine operation are therefore taken up both before and after the detail line printing. Thus to economise in the number of machine cycles the four lines of the address are printed concurrently with the four cycles which follow the last detail card so that the name and address of the customer appear at the foot of the invoice in line with the totals. The group reference number is punched in a certain field in each card and is sensed at both the upper and lower stations to afford automatic group control and to detect the inclusion by error in a group of cards, of any card belonging to another group, and if this occurs to stop the machine. Operation.-During the passage of the address cards the alphabetical information is printed by the alpha bank, Fig. 3 (centre). The plug socket 42 of the printing magnets of this are connected to plug socket 41 of the brushes of the lower brush station. On the passage of the first address card past the upper brushes MAJ relay is de-energized and relays LC4, LC5, and LC6PU are energized. A series of four cycles is now started by a circuit from line 12, cam contacts T3, MAJ, relay contacts 23B, plug socket 43 connection to plug socket 44, CYC4 relay to line 11. CYC4A contacts close to provide a holding circuit through P2. There is a shunt holding circuit through contacts CYC 3C, 2C, 1A and A and L9 (closed) to line 12. Contacts CYC 4B shift, completing a circuit from line 12, contacts 2C (closed), cam contacts P3 to CYC 3 relay. During each of the last four cycles an address card is fed and the data sensed and printed so that at the end of the operation the lines of the address appear alongside the final balance figures.

Abstract: 380,838. Straight bar knitting- machines. SCHUBERT & SALZER MASCHINENFABRIK AKT.-GES., 11, Lothringerstrasse, Chemnitz, Germany. June 24, 1931, No. 18267. Convention date, Aug. 1, 1930. [Class 74 (ii).] A method of widening applicable to stocking frames &c. consists in casting-on in a separate operation the yarn being presented without sinking to the penultimate needle of the series and laid round the selvage loop. This is done by deflecting the penultimate needle out of the line as the needles ascend. This needle by thus forming an unsunk loop requires less yarn than usual, so contributing to the formation of a form selvage. The needles are pressed individually by spring fingers 2 and a certain number of the end needles can be deflected by the action of sliding instruments 7 on the fingers. The instruments are operated by arms 9 mounted on a shaft 6 operated by a cam. The device is brought into or out of action by shogging a cam roller into or out of reach of the cam.

Title: Computer peripheral device control
IPC: G06F13/22
Filed: 1966-04-27
Abstract: 1,098,890. Control arrangement for computer peripheral devices. RADIO CORPORATION OF AMERICA. April 27, 1966 [May 5, 1965], No. 18409/66. Heading G4A. A computer peripheral device control comprises a basic processor unit 10 having start request outputs 41-44 for each of a corresponding number of peripheral devices 51-54, a threshold detector circuit 66 having a common input terminal 65, each of the peripheral devices having a busy signal output 57, an analog circuit 60 for each of the peripheral devices, having an input coupled to a corresponding start request output, and to a corresponding busy signal output, and having an output coupled to the common input terminal of the threshold detector, each analog circuit having an output signal value indicative of the proportion of the basic processor unit's time required in the servicing of the corresponding peripheral device, and gates 46 under control of the output of the threshold detector circuit conditionally for coupling the start request outputs of the basic processor to the peripheral devices. In operation an instruction in register U may request data from a peripheral unit 51. A start request signal is emitted on line 41 and passes switch 60 to render a transistor T1 conducting. A resistor 61 coupled to the threshold detector (Fig. 2, not shown) has a value inversely proportional to the servicing time of the peripheral device. If the current flow through resistor 61 is below the threshold of the detector 66 gates 46 are enabled and the peripheral device sends data and emits a busy signal keeping transistor T1 conducting. Later on other peripheral devices may be required. A similar process occurs for each unit until the total current flow through the resistors 61-64 passes the threshold value of the detector. This causes a signal to be emitted which inhibits gates 46 and, via lead 69 decreases by one the value of a programme counter 20 causing the computer to recycle through the preceding instruction after which the peripheral device is again accessed. Thus the computer passes into an idling loop until one of the peripheral devices completes its work and stops running. The idling loop arrangement may include a provision allowing interruption for the performance of a programme not involving a peripheral device unit. Each peripheral device unit may include a plurality of e.g. tape storage devices, magnetic disc devices, punched card readers or line printers, only one of which per unit is allowed to operate at any time.
