Abstract: 142,104. Grosser, G. F. [Firm of]. Dec. 10, 1914, [Convention date]. Parallel machines.-Relates to a type of machine described in Specifications 15963/10 and 12525/13, in which the web-holders or sinkers b are connected to the jacks' of the needles a, so that individual sinkers can be thrown in and out of action simultaneously with the associated needles. The needles are provided with jacks c<1>, c<2>, or c<3>, the jacks c<1>, c<2> having butt's 1, 2 situated at different distances from the ends of the jacks, while the jacks c<3> are provided with two butts 2, 3. The butts 1, 2, 3 may be stepped to give further variation of working. To knit a stocking of the shape shown in Fig. 10, commencing at the toe 12, the jacks are distributed in each bed as shown in Fig. 5<a>. All the loops of the stocking previously knitted having been pressed off excepting those on the needles required for commencing the new toe, work is begun on four needles of each bed, two of which have jacks c', while the other two have jacks c<3>. The jacks c<3> form a small group between the groups c<1> and c<2>. The groups c<1>, c<2>, c<3> are operated by means of slides 4, 5, 6 mounted on rails 7, 8, which are traversed in opposite directions by rack-and-pinion gear 9. The rails 7, 8 are mounted on transverse slides 10, 11, which can be moved in a direction at right angles to the length of the rails 7, 8 into positions determined by notches I - - V to bring the slides 4, 5, 6 underneath the respective butts 1, 2, 3. By this means the use of a pattern drum or chain is avoided. In the operation of the machine the device above described is moved up and down as a whole when it is required to throw needles in or out of action, and the operation on the needles will .be determined by the position of the slides 4, 5, 6 relatively to the butts 1, 2, 3. The ends of the slides 4, 5, 6 are reduced in height so that the corresponding jacks can be lifted to an intermediate position. Extra needles are thrown into action for widening the toe to the full width at 13 by acting on butts 1 and 2 of successive jacks on either side of the original group. Each jack on first being thrown into action is lifted halfway only. The fashioning of the heel pouch 14 is effected by the slide 6 acting on the butts 3 of the jacks c<3>, and the widening of the calf from 15 to 16 is effected by the jacks c<2> in a similar manner to the widening of the toe, except that needles are thrown into action on the right-hand side only. The necessary longitudinal and transverse movements of the rails 7, 8 are controlled by means of a cam wheel which throws pairs of ratchet pawls acting upon opposed ratchet teeth into or out of action as required.

Abstract: 1,055,704. Computer programming arrangements. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 16, 1965 [April 6, 1964], No. 10974/65. Heading G4A. In an electronic computer, a branch is determined by a comparison in which one comparand is the sum of two operands specified by the branch instruction. The (binary) address of the second comparand is obtained by ORing corresponding bits of the second operand's address and the number . 001. The branch instruction causes branch to an instruction address specified therein if the first comparand is greater than (or less than or equal to) the second comparand, and is used for incrementing and testing an index value when the second operand's address is even since then the second comparand's address is different from that of the second operand. Otherwise the two addresses are equal and the branch instruction test reduces to whether the first operand is greater than (or less than or equal to) zero. Comparison is by subtraction, byte by byte until a decision can be made.

Abstract: 436,952. Converting. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London. April 16, 1934, No. 11434. Convention date, April 14, 1933. [Class 38 (ii)] To avoid momentary interruption of connection in a system comprising A.C. and D.C. lines 1, 2 interconnected through a discharge device 8 having a reversing switch 12, 22 to allow of operation as a rectifier or as an inverter an auxiliary converter of any type is provided which is reversely connected with respect to the main converter and ensures the transmission of energy at the moment when the change in the connections of the main converter takes place. In the form shown, the auxiliary converter is a gridcontrolled discharge device 103 controlled by switches 112 and 122 to enable it to operate either as a rectifier or as an inverter. The operating coils 20, 120 are supplied from the D.C. mains 2 through a resistance 21 and the coils 30, 130 through a resistance 31. For rectifier operation the coils 20 and 130 are energized, the circuit of coil 20 being completed through a closed contactor 29 on the switch 22 and the circuit of coil 130 being completed through closed contactors 119 and 28 on the switches 112 and 22. The moment of reversal of the connections of the discharge device 8, due to change in the voltages of the mains 1, 2, is determined by means of a polarized relay 39 in the circuit of the auxiliary device 103. This device will operate as an inverter, as the voltages alter and when the current rises above a predetermined minimum, the relay 39 operates closing the contacts 40, 42 to short-circuit the coil 20 and cause the switch 12 to open. The operating coil 30 is energized through contacts 19 and the switch 22 closes, completing the connections of the discharge device 8 for operation as an inverter. Closure of the switch 22 de-energizes the coil 130 so that switch 122 opens. Finally, the coil 120 is energized through contacts 129 and 18 causing closure of the siwtch 112 completing the connection of the discharge device 103 to the circuit as a rectifier. The grid circuit connection are altered by means of contacts on the various switches. By this arrangement the switches 112, 122 cannot operate until after the switches 12, 22 have operated. To change from inverter to rectifier connection the contacts 41, 42 close. To avoid hunting of the switches on starting of the installation, the switch 34 which completes the operating coil circuits is arranged so that one of its contacts 32, 33 closes before the other. In a modification, the converter 10 is a motor generator set.
