Title: Improvements in or relating to electro-magnetic driving mechanism particularly suitable for actuating a rheostat switch
IPC: H02K7/065
Filed: 1932-06-29
Abstract: 400,723. Electromagnetic switches. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London, and TUPPEN, E. B., 54, Hillmorton Road, Rugby. June 29, 1932, No. 18402. [Class 38 (v).] An intermittently-operating electromagnetic driving mechanism which may be used in the control of a rheostat comprises a toothless double-acting ratchet device actuated to rotate a shaft in either direction by electromagnetic solenoid-operating means. The toothless double-acting ratchet mechanism comprising a rotatable member having a cylindrical inner surface, and a cam member for each direction of rotation pivoted about the axis of the rotatable member having a curved working surface co-operating with the inner surface of the cylindrical member so that a spring-pressed roller or ball locks the rotatable member and cam together for at least part of the forward movement, a fixed stop being provided so that the rotatable member is unlocked during return movement of the cam member. As shown in Fig. 6, two solenoids 14, 15 have their cores 16, 17 connected by links to arms 2, 3, Fig. 2, loosely mounted on a shaft 18. When either solenoid is energized the movement of the core causes a cam surface carried by the arm 2 or 3 to wedge a roller 7 or 8 against a flange of an outer drum keyed to the shaft, so stepping round the drum and shaft. When the electromagnet is de-energized the core returns under spring action and the roller is released, the drum remaining in its displaced position and the roller being returned by a spring 9 or 10 and distance piece 11 or 12 to rest against a stop 5 or 6 in readiness for a subsequent operation. Each electromagnet may be provided with a snap action switch in its energizing circuit so that while a corresponding pushbutton is maintained depressed a continuous stepping round of the shaft 18 takes place in one or other direction and a contact arm mounted thereon may be moved intermittently across contact studs connected to sections of resistance. The snap action switches for interrupting the electromagnet circuits may be of the type shown in Figs. 3 and 4, in which the movement of a rod 23 connected to the solenoid core brings two pivoted arms 28, 29 across the line of action of springs 24 connecting their outer ends so snapping them across to their opposite positions in which they rest against fixed stops 22, 22a, an insulated bridging contact 26 being thereby moved rapidly out of contact with posts 21 acting as contacts in the corresponding electromagnet circuit. Other forms of quick-action switches may, however, be employed. When used for operating a rheostat the contacts may be arranged in a circle, the movable contact arm being driven from the shaft 18 either directlv or through gearing, or, alternatively, the contacts may be arranged in line, the movable contact being driven by screw or nut mechanism or by sprockets and a chain. In this form limit switches may be provided at the ends of the movement of the movable contact.

Title: An apparatus for measuring small variations in resistance in a bridge connection by means of alternating current
IPC: G01R17/10
Filed: 1926-07-24
Abstract: 274,280. Marks, E. C. R., (Akt.-Ges. Brown, Boveri, et Cie). July 24, 1926. Vacuum gauges. - An alternating-current wheatstone bridge for measuring small variations of resistance such as occur in resistance thermometers has two diagonal corners connected to the rotating coil of an iron-cored dynamometer, while the external circuit of the other diagonal contains a self-inductance or capacity. Fig. 1 shows a hot-wire vacuum meter in which the degree of vacuum is measured by the rate of cooling of two heated resistance wires a, c of high temperature coefficient forming two arms of a wheatstone bridge, of which the other two arms are formed by resistances b, d. Alternating current from a source f is supplied to the points B, D of the bridge, heating the wires a, c, but producing no potential difference across the points A, C when the bridge is balanced. The points A, C are connected to a moving coil h moving in the field of an alternating-current electromagnet g excited by a coil e connected to the source f either directly or through a transformer wtih or without the interposition of a series resistance, for example an iron wire in hydrogen. The rotating coil h consists of two coils connected in series and mechanically coupled at 90‹ or other fixed angle as shown in Fig. 5. One coil acts as a transformer and supplies current for heating the bridge, the other coil acting as a motor and producing, with the compensating current of the bridge, a torque which causes a deflection of the coil against the action of a restoring spring i. Variation of vacuum causes variation in the rate of cooling of the wires a, c, causing a variation of their resistance and thereby causing unbalance of the bridge. A choking-coil k, or a condenser, is introduced into the circuit connected to the points B, D in order to produce the necessary phase relationship between the current in the .coil h and the flux of the magnet g. Alternatively the exciting-coil e may be connected in series with the points B, D, serving as a choking-coil. The points B, D in this case are joined by a resistance, as the magnetizing current of the coil e is greater than that required for the bridge. In the arrangement shown in Fig. 5 the bridge is fed from the coil h only, the diagonal points B, D being joined by a choking-coil o.

Title: Improvements in or relating to a electron discharge apparatus in which a flattened or ribbon-shaped electron beam is employed
IPC: H01J29/62
Filed: 1944-09-30
Abstract: 609,480. Electron discharge apparatus. KLEMPERER, O. E. H. Sept. 30, 1944, No. 18765. [Class 39 (i)] Electron discharge apparatus generates a flattened or ribbon-shaped electron beam with a waist or cross-over at a line substantially parallel to the major axis or dimension of the cross-section of the beam, equi-potential surfaces in the path of the beam in the vicinity of the cathode being convexly curved so that the beam will be initially convergent in a plane extending longitudinally of the beam, and containing the major axis of the beam crosssection. The apparatus shown in Fig. 1c comprises a curved strip cathode C behind a slot in the diaphragm D of the control electrode G, a tubular anode A having a pair of oppositely disposed extensions L and an anode E. The extensions L are formed as described with reference to Fig. 4 of Specification 574,056. The emissive surface of the cathode C may be curved in the YZ plane as well as the XZ plane. The anodes E and A are maintained at suitable positive potentials with respect to the cathode C, the anode A being at a higher potential than the anode E and the control electrode G is maintained at a suitable low, zero or negative potential with respect to the cathode C to cause a beam of electrons of substantially rectangular cross-section to pass through a cross-over at a line near the cathode C and diaphragm D and to be focused by the extensions L on the anode A to form a line image of the cross-over. In the arrangement shown in Fig. 3b, the control electrode G and the anode E are in the form of cylindrical tubes and the slotted diaphragm D of the control electrode G, and the emissive surface of the cathode C are spherically curved. The anodes E and A include circularly apertured diaphragms D1 and D2 respectively preventing undue spreading of the beam. If a high current intensity is desired rather than a sharp line image, an arrangement similar to that shown in Fig. 3b can be used in which the anode E is formed without any projections. A magnetic focusing field could be employed in the arrangement shown in Fig. 3b instead of the electrostatic focusing field set up between the anodes A and E. In the construction shown in Fig. 4a, the cathode C and control electrode diaphragm D are not curved, but the control electrode G has an extension H beyond the diaphragm D, the end of the extension lying in a plane. In the construction shown in Fig. 5c, the control electrode G and anode E are of rectangular cross-section and the edges of opposite sides of the extension H of the electrode G are curved, the adjacent edges of the anode E being preferably curved in a complementary manner. The electrode G may comprise a pair of plates arranged parallel to the longer sides of the cathode and having extensions on their longer edges which are outwardly turned. The electrode G need not function as a control electrode but may merely serve as a cathode screen.
