Title: Improvements in or relating to gasfilled discharge tubes
IPC: H01J17/04
Filed: 1931-10-24
Abstract: 377,041. Disc:harge apparatus. NAAMI,OOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, 13D, Emmasingel, Eindhoven, Holland. Oct. 24, 1931, No. 29558. Convention date, Oct. 31, 1930. [Class 39 (i).] A gas-filled tube such as a rectifier or a neon lamp has an incandescent cathode 2 surrounded by a metallic sleeve 15 and is provided with an ion catcher 6 which is located on the side of the cathode remote from the anode and extends beyond the open ends of the sleeve. The ion catcher may be connected to the sleeve and through a resistance or directly to the cathode by means of a bush 16 which is fitted on a cathode leadin wire and is flanged at its upper side. The sleeve and catcher are also connected at 18. The catcher may be cup-shaped or consist of a plate formed with an upstanding edge. Quartz tubes 11 and a steatite tube 14 protect the lead-in wires. The lower portion of the tube is kept comparatively cool by means of a mica heat shield 19, and the temperature of this portion determines the pressure of the filling more particularly when the tube contains a vaporizable solid or liquid such as mercury generating a vapour filling. A number of anodes may be used. The Specification as open to inspection under Sect. 91 (3) (a) states also that the sleeve 15 may be dispensed with [Fig. 1, not shown (Cancelled)], and the anode arm may be connected to the main portion of the bulb through a metallic sleeve which may be given a potential facilitating starting ; a number of cathodes may be used. This subject-matter does not appear in the Specification as accepted.

Abstract: 799.133. Winding reserve lengths of yarns. COURTAULDS, Ltd. Oct. 17, 1956 [Oct. 18, 1955], No. 29650/55. Class 120(2) A ring spinning and twisting machine in which the ring and the spindle are axially reciprocable with respect to each other, includes mechanism, to enable a tail to be wound about a part of the spindle not normally traversed by the ring, which gives the ring an additional relative axial displacement and includes a latch to maintain said displacement and a part movable relative to the latch and adapted to disengage the latch at a predetermined point in the traversing cycle. In the embodiment shown the ring holder 4 is carried in a rail 3 adjustably supported on a plunger 2 which can slide vertically in a channel shaped ring rail 1 reciprocated vertically in known manner. A cam member 8 is pivoted at 9 to the lower end of plunger 2. In operation the plunger 2 is depressed so as to lower the ring into a position for winding a transfer tail in the groove 15 of bobbin flange 14 and the cam member 8 pivots to the position shown in Fig. 2, thus retaining the plunger 2 in the depressed position. An arm 10 on the cam 8 pivots past a fixed projection 11 on the down stroke but on the upstroke is engaged by it so that the cam 8 is turned to its original position and thus the plunger 2 and the ring holder 4 return to the normal position under the action of spring 7. In a second embodiment the ring rail is fixed and the latch is operated by movement of the spindle and in a third embodiment the additional movement of the ring is achieved by rotating it, pins on the ring engaging slanting slots on the holder so as to provide axial movement.

Title: Radio-interference-suppressing chokes

Filed: 1973-06-25
Abstract: 1416403 Inductors SIEMENS AG 25 June 1973 [14 Sept 1972] 30042/73 Heading HIT A radio-interference suppression choke for attentuating asymmetrical and symmetrical parasitic current comprises, on a closed annular ferromagnetic core, at least two windings serving to produce in the closed core mutually cancelling magnetic fluxes due to the working current; and within the window of the closed core an unwound core member having radial arms each spaced from the closed core with a non-magnetic gap. For single-phase circuits an annular ferrite core 1, Fig. 1, is bridged by a ferrite member 5, supported by insulative shims 6 in the non- magnetic gaps 2 and fastened with adhesive. Two windings on the closed core on opposite sides of the gapped member 5 are connected in respective power leads so that the working current, together with symmetrical parasitic currents, induces magnetic fluxes which are mutually cancelling in the closed core 1 but follow parallel paths 4 in the gapped magnetic circuit. The inductance due to this flux has an impedance which, while low at the working frequency, can be made adequate at radio-interference frequencies. Asymmetrical currents, i.e. those unbalanced with respect to earth, induce non-cancelling fluxes in the closed path 3 and so meet the full impedance of the closed core 1. A core suitable for a four-wire system is illustrated in Fig. 2.
