Title: Improvements in or relating to band electric filters
IPC: H03H7/01
Filed: 1929-02-08
Abstract: 306,896. Telefonaktiebolaget L. M. Ericsson. Feb. 27, 1928, [Convention date]. Filter circuits.-Relates to filters in which a section of the band-pass type is linked with one of the band-rejector types in such a way that the input terminals of several such filters can be connected in series while their output terminals are connected in parallel, or vice versa; and consists in a particular choice of dimensions of the impedances z1, Fig. 1, may be connected to a circuit of impedance z2 through a filter comprising a rejector circuit L1, C1, coupled inductively with am acceptor circuit L2, C2. The input and output characteristic impedances are plotted against frequency in Figs. 2 and 3 respectively; thus the input impedance is of the band rejector type, Fig. 2, and falls off rapidly above and below the vertical frequencies, f<1>, f<2>, while the output impedance, Fig. 3, is of the band-pass type, and rises rapidly above and below these frequencies. The condenser C2 may be replaced by two series condensers symmetrically connected on opposite sides of the inductance L2 (Fig. 9, not shown). The transformation ratio of the coupling L1, L2, is adapted to the ratio of the terminating impedances z1, z2, Fig. 1. The rejector side may form part of the plate circuit (Fig. 4, not shown), or grid circuit (Fig. 5, not shown) of a valve, and in this case the internal capacity of the electrodes and the coil L1 is allowed for in the calculation of the capacity C1 or C2. Chain filters comprising sections of the type described may be constructed as indicated in Figs. 7, 8. The transformer may be replaced by an equivalent network as shown in Fig. 10. Where a number of filters is used to connect a single input circuit with a plurality of output circuits, or vice versa, the rejector terminals 1, 1, of the several filters may be connected in series (Fig. 11, not shown), or their acceptor terminals 2 may be connected in parallel (Fig. 12, not shown), the remaining terminals being connected to separate circuits. In each case the impedances, cut-off frequencies and coupling coefficient are related according to a formula given in the Specification.

Title: Electric arc welding
Inventor: BLACKHURST GEORGE BENJAMIN

Filed: 1956-02-13
Abstract: 818,591. Welding or cutting by fusion. BRITISH OXYGEN CO. Ltd. Jan. 30, 1957 [Feb. 13, 1956], No. 4454/56. Class 83 (4). [Also in Group XXIX] Apparatus for automatically maintaining a substantially constant arc length between a mechanically supported electrode and a workpiece, e.g. for welding with consumable or non- consumable electrodes or for electric arc cutting, comprises a pressure responsive member adapted, under the influence of a varying applied pressure provided by a substantially continuous flow of gas against a biasing force, to raise or lower a head supporting the electrode, and means responsive to the arc voltage for controlling the flow of gas and thereby the pressure applied to the pressure responsive member to raise or lower the head supporting the electrode to maintain the arc length substantially constant. In an embodiment, a flexible diaphragm 20, Fig. 1, supported in a casing 8 is secured to a stem 7 movable between guide rollers 11 and carrying a welding head 3 having an electrode 2 positioned above a workpiece 1. Diaphragm 20 is responsive to the pressure of air which is supplied to the casing continuously from a source 14 through pressure regulator 16 and is exhausted through an outlet pipe 13. Inlet and outlet valves 15, 18, respectively, are actuated, e.g. by solenoids energized from a relay-sensitive to changes of arc voltage, and the speed of response of the diaphragm is adjustable by needle valves 17, 19, respectively, in the inlet and outlet pipes. When the arc length is constant at its normal length, inlet and outlet valves 15, 18 are both open. Any substantial increase or decrease of arc length, leading to a corresponding increase or decrease of arc voltage, causes closure respectively of outlet valve 18 or inlet valve 15 until normal arc length is restored by the corresponding build up or reduction of air pressure above diaphragm 20. The diaphragm is spring biased. In a modification (see Group XXIX) the pressure responsive member is a piston biased by its own weight and that of a mass of oil and by the elastic restoring force of a rubber bellows connected to an oil containing space above the piston.
