Title: Improvements relating to electric timing circuits using cold-cathode gas discharge tubes
IPC: B23K11/24
Filed: 1947-01-29
Abstract: 628,635. Valve relay circuits. HIRST ELECTRONIC DEVELOPMENT, Ltd., and BRAMSON, S. M. Jan. 29, 1947, No. 2782. [Class 40 (vi)] A timing circuit comprises three resistors and a cold-cathode gas discharge tube connected in the four arms of a Wheatstone bridge circuit, a source of potential being connected across opposite corners of the bridge and a relay in series with a rectifier connected across the other corners, a capacitor is connected across the control gap of the tube so that the timing period commences with the operation of the relay and terminates when the capacitor has charged sufficiently for the tube to fire and the relay to release. The Figure shows a timing circuit in which when the initiating switch H is closed rectifier G conducts and relay F operates, thus closing contact F<3> and operating the contactor J in the circuit of the apparatus to be controlled. Simultaneously, hold-on contact F<4> is made and capacitor C<2> charges via contact F<2> and resistor R' until the cold-cathode tube A fires. The consequent flow of current through the tube increases the potential drop across the anode resistors R3, R<4>, and no current flows through the relay F. The relay thus releases to break the contact F<3> in the work control circuit and to discharge capacitor C<2> via con- , tact F<1> and resistor R'. The timing period may be adjusted by variation of the charging resistor R<7>.

Title: Improvements relating to the manufacture of combustible gas
IPC: C10J3/00
Filed: 1930-01-28
Abstract: 338,804. Humphreys & Glasgow, Ltd., (Assignees of Kunberger, A. F.). March 2, 1929, [Convention date]. Water-gas plant.-In the manufacture of water gas, hydrogen produced by passing steam over hot iron is superheated and carburetted and then passed with excess steam through the upper part of the fuel bed, the whole of which is used simultaneously in generating water gas by uprunning, the mixed gas being taken off above the fuel bed. The blow gases pass from the generator 1 to the carburettor 7 and from thence to the vessel 10 containing hõematite, ore. The latter is reduced to iron sponge which is heated by the blast. The iron is then steamed, hydrogen being produced which passes with excess steam through the carburettor, where oil is injected through 9, to the upper portion of the fuel bed 2. Simultaneously the generator is steamed by up-running at 4, the mixed gases passing to the offtake 5. The Specification as open to inspection under Sect. 91 (3) (a) describes also a generator modified for down-steaming and an arrangement wherein an igniter may be substituted for the carburettor. Hydrogen and excess steam pass down through the fuel bed to be followed by an up-run or the mixture may bye-pass the water gas generator and be subsequently mixed with water gas or blue gas produced by up or downsteaming. The igniter may be superheated by steaming before passing the steam to the generators. In a further modification, a carburettor and a superheater may be placed after the hydrogen generator, the superheater being steamed before the generators. This subjectmatter does not appear in the Specification as accepted.
