Patent GB-657604-A (GB)
Title: Improvements in or relating to accounting and similar calculating machines
Inventor: WALLACE JAMES
IPC: G06C7/06
Filed: 1949-02-21
Abstract: 657,604. Calculating-apparatus. NATIONAL CASH REGISTER CO. Feb. 21, 1949, No. 4628. [Class 106 (i)] In a calculating-machine having a totalizer, actuator therefor, a common member for moving the actuator in setting and return directions, a totalizer engaging and disengaging mechanism and zero stops for the actuators which also hold the latter against further setting movement after the totalizer has been disengaged in total-taking operations, each zero stop has a series of teeth which co-operate with an abutment on the related actuator, said zero stops being automatically controlled, during a total-taking operation, so as first to be disabled while the actuators are set under the control of the totalizer and then rendered effective, before the totalizer is disengaged, to re-engage the teeth with the abutments to hold the actuators against further movement in the setting direction. In each denomination, depression of a key 5 shifts a slide 6 which rocks the zero stop 3 counter-clockwise out of engagement with a block 2 on the differential actuator 1. In total-taking operations, a lever 15 is rocked by depression of the totaltaking key to remove a stud 16 from the path of a pawl 17 which is then rocked counterclockwise by a spring 39 so that a notch 32 in the pawl engages a stud 18 in an arm 19. During the ensuing operation, a stud 21 in a disc 20 on a camshaft 33 rocks the arm 19 counter-clockwise to draw a slide 23, on which the pawl 17 is pivoted, to the right. A projection 25 of the slide 23 rocks an arm 26 fast on a shaft 27, and studs 29 in arms on this shaft co-operate with projections 30 on the slides 6 to cam the latter to the left, thereby disengaging the zero stops 3. A bail 8 is then moved to the right and each actuator 1 is urged to follow by a spring and drives its associated totalizer wheel 9 to its zero position. The totalizer wheels are then disengaged from the actuator, and at this time, a stud'22 in the disc 20 engages the pawl 17 and disengages it from the stud 18 to enable the slides 6 to be restored by their springs. The zero stops 3 are thus freed and teeth 4 therein engage the blocks 2 to hold the actuator in their set positions. When the actuators are restored by the bail 8, the blocks 2 ratchet over the teeth 4 of the zero stops. Each actuator is coupled, in the usual manner, by means of a lever 10 and a link 12, to a printing segment 11 and a justifying bar 13 co-operates with teeth in the levers 10. Specifications 506,500 and 509,042 are referred to.

Title: Improvements relating to electronic timing circuits
IPC: H03K3/10
Filed: 1947-02-19
Abstract: 631,678. Pulse generating circuits. SCOLES, G. J., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 19, 1947, No. 4854. [Class 40 (vi)] In a flip-flop circuit in which the duration of the unstable state is terminated by a retriggering signal applied to the cathode of the valve which is then non-conducting, the amplitude of signal required to perform this action is reduced by means of a feed-back circuit between the anode and control grid of the cut-off valve which applies a signal to the grid of the valve to oppose the negative potential which causes the valve to be non-conducting. The Figure shows valves V1, V2 arranged in a cathode-coupled flip-flop circuit, the time constant of the network R2, C1, being very long and the unstable state when V2 is non-conducting being terminated by a signal applied across resistor R3. The anode of valve V2 is connected to its control grid via resistor R5 and capacitor C1 so that during the unstable state when valve V2 is cut-off by a negative voltage at its control grid the positive rise of voltage at its anode is fed back to the grid to reduce the negative potential there and thus to enable the flip-flop to be retriggered back to its initial stable state by a signal of relatively small amplitude. The feed-back is controlled by a capacitor C2 connected between the anode of V2 and a point of fixed potential. Initially, due to the presence of C2 the anode potential of V2 does not vary but subsequently when V2 is cut-off capacitor C2 will charge through resistor R4. The pulse appearing at the anode of valve V may be used to trigger a discharging valve V3 connected across a capacitor C4 in a sawtooth generating circuit. Specification 612,244 is referred to.

Abstract: 834,551. Thermally treating yarns. SEEM, W. A., STODDART, N. J., TECCE, F., and BERGER, H. P., [trading as PERMATWIST CO.]. Feb. 17, 1956 [Feb. 21, 1955], No. 4952/56. Class 120(3) Resin treated yarns of natural fibres or rayon are continuously thermally processed to shrink, stretch or stabilize them by passage through an automatically regulated zone of dry heat at constant tension, a predetermined correlation being maintained between applied tension and the contractible force of the resin treated yarn. The process is preferably effected on yarn while being twisted by a false-twist device and crimped or bulked effects may be obtained. Thermoplastic and/or thermal setting resins, including such materials as urea formaldehyde and polyamides, may be applied to cotton, linen, rayon, silk, wool and like yarns immediately before thermal processing as by passage through an applicator 95, or there may be an interval between the steps. The yarn may be dyed during processing by passage through the applicator 95 which in such case, would contain a dye that could be developed and set in the heating zone. Compound yarns may be produced by plying one thermally processed end with an unprocessed end and thermally processing the doubled yarns. The apparatus employed may be as described in Specification 803,105.
