Title: Improvements relating to bobbin-winding mechanism for sewing machines
Inventor: LESLIE IVAN ALEXANDER
IPC: D05B59/00
Filed: 1961-10-28
Abstract: 959,332. Sewing machines. JOSEPH SANKEY & SONS Ltd. Jan. 25,1963 [Oct.28, 1961], No. 38663/61. Heading D1G. In a sewing machine bobbin-winding device having a bobbin-receiving spindle rotatable by a wheel moveable bodily into and out of engagement with a drive wheel, and a movable shoe engagable by. the peripheny of thread wound to a predetermined depth on a bobbin to disengage the movable wheel from the drive wheel, a control lever, carrying skid shoe and a finger piece, is manually movable by the finger piece to press upon a spring-biased lever to turn the latter to a position in which a stop part of the control lever lockingly engages a part of the spring-biased lever and the movable wheel engages the drive wheel, the control lever being also movable by the finger piece to its initial position in which the shoe is shifted clear of the bobbin and the spring-biased lever is tripped to disengage the movable wheel from the drive wheel. As shown, a spindle 3, carring a wheel 5 and adapted to receive a bobbin 26, is journalled in an arm 11 which is pivoted at 12 to a lever 6 and is biased by a spring 13 against a lug 14 on the latter. One end of lever 6 is pivoted at 7 to the machine frame and the other end has a slot 18 engaged with a fixed pin 17. A control lever 9, pivoted at 10 on the machine frame, carries on one arm a finger piece 23 and on the other arm a shoe 25 disposed adjacent the bobbin 26. In the inoperative position of lever 9, finger piece 23 is raised, and a spring 15 connected between levers 6 and 9 biases lug 19 on lever 6 against an edge 28 on lever 9. If finger piece 23 is depressed to shift lever 9 to the operative position, shoe 25 is moved nearer the bobbin and lug 19 enters a notch 29 in lever 9 to shift wheel 5 into engagement with a driving wheel 16. Thread wound on bobbin 26 to a sufficient depth engages shoe 25 to trip lever 6 for disengaging wheel 5 from wheel 16. Lever 9 may, however, be returned at any time to the inoperative position, by manipulation of finger piece 23,to trip lever 6.

Title: A Device for Correcting Errors in the Course of Transmission and Arithmetical Processing of Information
Inventor: AKUSHSKY IZRAIL YAKOVLEVICH
IPC: G06F11/10
Filed: 1967-08-23
Abstract: 1,189,700. Error detecting and correcting. I. Y. AKUSHSKY and D. I. G. JUDITSKY. 23 Aug., 1967, No. 38849/67. Heading G4A. Errors in a digital computer are corrected, using residue coding, subtracting stored constants to zeroize successive digits and detect an error, the erroneous digit being determined from indications from successive checks and corrected. A number in a computer is represented as its residue on division by each of a number of relatively prime radices, the residue for a redundant radix greater than the other radices being attached for error checking purposes. For error checking a series of constants are selected from storage and subtracted from the number (in the case of the first subtraction) or from the result of the previous subtraction, the jth constant being selected in accordance with the jth position (residue) in the number (in the case of j = 1) or in the result of the previous subtraction (for other j) each constant being such as to zeroize the position which selected it. After each position except that corresponding to the redundant radix has been used the latter position should be zero. If not, indicating an error, the identities of the positions which could be in error (as determined by the value of the position corresponding to the redundant radix) are stored. Subsequent arithmetic operations with the number which has just been checked will produce results which will also be in error, the positions which could be in error being indicated in each case as before. The position actually in error must be the same in the original number and in the results derived from it and so will be in each of the sets of possibly erroneous positions. After a few results have been produced, there will be only one position common to all the sets and this position is corrected by adding in a constant selected in accordance with the value of the position corresponding to the redundant radix. Specification 1,189,699 is referred to.

In a gramophone of the type described in Specification 909,859 the sizing arm 94 is pivoted at 95 to an arm 96 pivoted at 97, and is moved to perform a sizing operation by pivotal movement of a plate 104 provided with a slot 105 receiving a pin 102 which also engages a cam slot 101 in a fixed guide plate 99. To- and-fro motion imparted to a driving arm 79 during a cycle of the control unit 51 (not shown) causes the pin 102 to travel round the cam slot 101, and thereby causes the free end of the arm 94 to follow the path shown in chaindotted lines.
