Abstract: 929,151. Winding toroidal cores. TESLA NARODNI PODNIK. May 2, 1961 [May 2, 1960], No. 15848/61. Class 83 (4). Apparatus for winding wire in layers on a sector of a toroidal core includes means for reversing the rotation of a core carrier at positions corresponding to the ends of the layers. Wire from a carrier 13, rotated through a core 11 on a rotated carrier 15, is wound on the core until an arm 18, driven from the carrier 15, engages the appropriate contact on a disc 16. Whereupon relay means is actuated to disengage an electromagnetic clutch 28 in a drive means 27 to the wire carrier 13 and core carrier 15 and to engage a brake 26. A clutch 22 then disengages the drive from the means 27 to core carrier drive means 20 and engages a reverse drive from means 33 to the core carrier 15. The carrier 15 thus moves in a reverse direction, no winding of the wire taking place, until the arm 18 engages another contact on the disc 16 to cause the reverse movement to stop. The drive 27 then rotates the core carrier 15 and wire carrier 13 to wind the next layer. A hook member 14 moves the wire coming from the carrier 13 to a position at the start of the winding of the layer just before winding of the layer commences. Means for counting the number of turns of wire wound is provided. Two motors may be provided, one for the means 27 and one for the means 33.

Title: Improvements in or relating to checking circuits for electronic asynchronous add or subtract registers
IPC: G06F7/505
Filed: 1960-05-05
Abstract: 875,153. Transistor logic circuits. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 5, 1960 [May 11, 1959], No. 15967/60. Class 40(6) [Also in Group XIX] Logical circuits including P-N-P transistors and Zener diodes are employed in an arithmetic unit including checking circuits (see Group XIX). In an exclusive-or circuit (Fig. 3) output terminal Z1 is positive, terminal Z2 negative if inputs X1 and X2 are of like polarity, and if inputs Yl and Y2 are of like polarity. Circuit parameters are chosen so that the currents flowing are those indicated on the diagram irrespective of the switched state of the transistors. If, for example inputs X1, X2 are positive, Y1, Y2 negative, transistor 24 is conductive, transistor 34 is cut-off resulting in 4Ma of current being supplied to lines 27, 22 by sources 26, 36 respectively. Since source 23 draws 10Ma, 6Ma passes Zener diode 38 of which 4Ma is supplied from source 37. The remaining 2Ma is drawn from ground across resistor 39 which makes Z2 at a negative potential. A similar analysis shows Zl to be positive under the given input conditions. An identical circuit is modified only in its output arrangements, dispensing with diode 38, source 37 and terminal Z2 (Fig. 4, not shown). Fig. 5 shows a circuit in which Z1 is positive, Z2 negative, if at least two of the inputs Al, B1, Cl are positive. Under this condition at most 2À5 Ma is supplied to line 90, necessitating current being drawn from earth across resistor 94 rendering Z2 at negative potential.

Abstract: 835,144. Discharge lamps. GENERAL ELECTRIC CO. Ltd. May 20, 1958 [May 21, 1957], No. 16118/57. Class 39(1). A low pressure mercury vapour fluorescent discharge lamp containing rare gas at a few mms. pressure for starting has the area of crosssection of the envelope at one end at least reduced by the inward deformation of the envelope wall over a region 9 between the electrode 3 at that end and the adjacent end of the envelope so as to allow the passage of liquid mercury but to restrict the transfer of heat by convection from the space between the electrodes to the space between the constriction and the adjacent end of the envelope. The crosssectional area of the interior of the envelope in the constricted region is about one third of that of the part of the envelope between the electrodes. The rare gas filling for starting can be neon or a mixture of 80% neon, and 20% argon, or 60% neon and 40% argon, at a total pressure of 2 mms., the percentages being in respect of total pressures. The constriction in the envelope can be formed by squeezing the heat-softened glass of the envelope between a pair of opposed jaws to produce a flattened region. Alternatively an annular depression may be formed in the wall of the envelope by rotating the heated envelope and using a shaping tool.
