Abstract: 265,950. British Thomson-Houston Co., Ltd., (Assignees of Newman, D. F., and Steenstrup, C.). Feb. 15, 1926, [Convention date]. Resistance furnaces.-In an electric furnace, adapted particularly for uniting parts by fusion of metal, annealing, and other operations in which an inert atmosphere such as hydrogen is used, means are provided for inserting and withdrawing part of the charge without exposing the remainder of the charge within the furnace to the atmosphere. As shown in Figs. 1 and 3, the furnace comprises a hearth 6, rotatably mounted on a base 5 and fitted with a handle 30, and a cover 7 which is provided with resistors 10 and a valved inspection tube 29 and is supported, so as to be vertically movable, by a rod 15 attached to a piston working in an hydraulic cylinder 16. The hearth 6 and cover 7 are both heavily lined with fire-brick 8, and escape of hydrogen, which is supplied under slight pressure by a pipe 17, between the two parts is prevented by a labrynth packing comprising concentric rings 20, 21 carried by the cover and the hearth respectively, the space between the rings being filled with steel shot or sand. The rings 20 are formed with apertures 25, Fig. 3, which register with one another to provide, when the cover 7 is raised slightly, an opening through which a portion of the charge 14 may be removed or a fresh portion inserted, a removable plate 26 being provided to form a charging and discharging platform. The upper and lower edges of the apertures 25 and the bottom edges of the rings 20 are chamfered to prevent adherence of and to facilitate entry into the packing material. Separate apertures for charging and discharging may be provided. In the modification shown in Fig. 6, the rotatable hearth 44 is formed with a circular series of charging openings 50 into which work supports 57 are adapted to be raised and secured by hooks 58, a packing, similar to that at 41, 42, being provided between the hearth and the supports. The mechanism for raising and lowering the supports 57 comprises a plunger 56 working in a fixed hydraulic cylinder 55, the arrangement being such that as the hearth is rotated by the handle 59, the openings 50 successively come into register with the plunger 56 which, after release of the hooks 58, is operated to lower the support 57 from which the charge is transferred to the table 60. The new charge, which may be mounted on the same support or on a fresh one, is then inserted by raising the plunger 56, the support being secured in position by the hooks 58. The central part of the hearth 44 is fitted with an additional heating element 61. In both modifications, during the actual charging operations, the supply of hydrogen from the pipes 17, 47 is increased sufficiently to cause the gas to extend into the charging and discharging openings.

Filed: 1920-01-30
Abstract: 138,366. Goldschmidt, R. B. Nov. 18, 1913, [Convention date]. Drawings to Specification. Electric oscillations, producing. - In known arrangements for the shock-excitation of a persistently-oscillating secondary circuit by the discharge of a condenser in a primary circuit, the oscillation in the primary circuit is quenched by the resistance of the spark. According to the present invention, the primary oscillation is quenched by a virtual resistance, such as an inductively-coupled energy-consuming circuit, or a device for wasting energy in the form of hysteresis losses, or Foucault currents set up in a mass of metal. The characteristics of the damping-circuit are chosen so that the absorption of power is delayed, and only becomes appreciable after the first maximum amplitude of the primary current.

Title: Improvements in or relating to radio and the like amplifiers
IPC: H03J3/28
Filed: 1929-01-29
Abstract: 328,575. Round, H. J. Jan. 29. 1929. Thermionic amplifiers.-In a cascade-connected thermionic amplifier having " gang-controlled " tuning circuits, imperfect matching of the tuning elements is compensated by making the damping of one tuned circuit considerably less than that of the other tuned circuits, the arrangement being such that the total overall resonance curve corresponds to that obtained if all tuned circuits have substantially uniform damping. The differences in damping are obtained either by winding the coils in the tuned circuits of wires of different resistances or by connecting a resistance shunt across one or more of the tuned circuits. Except as regards damping, the tuning circuits have the same physical dimensions.
