Patent GB-787134-A (GB)
Title: Manufacture of combustible gas
Inventor: WILLIAMS NORMAN HENRY
Filed: 1955-06-02
Abstract: 787,134. Gas manufacture. HUMPHREYS & GLASGOW, Ltd. May 2, 1956 [June 2, 1955], No. 15887/55. Class 55 (2). In a process for converting liquid or gaseous fuels into combustible gases by contacting the fuel with steam in the presence of a catalyst, which process is operated by cyclic alternation of plant-heating and gas-making phases, overheating of the catalyst bed by combustion of the deposited carbon during the heating phase is prevented by passing additional steam or other gasefication medium therethrough during the gas-making phase, but after the supply of gas-making fuel has been ended, the resulting gas of high carbon dioxide content, being kept separate from the main product gas. As shown, the catalyst bed 10 is supplied at 11 with superheated steam and at 12 with fuel. The main product gas passes via a seal 16 and valve 17 to storage. When the fuel supply is ended, the steam supply at 11 is continued to react with the carbon in the bed, the water gas either passing through a combustion-air regenerator 14 for collection via a seal 19 and valve 20, the valve 17 being closed, or being burned with air admitted at 23 before passing through the regenerator to the stack 21. Steaming may be at a higher rate during the period of carbon removal than during the fuel supply period. If the catalyst is an oxidizable one such as a nickel catalyst, gas containing a high proportion of carbon dioxide may be produced during the reduction of the catalyst, i.e. at the beginning of the oil supply period. This gas may, likewise, be removed separately from the main product gas for storage and used for plantheating or steam-raising.

Abstract: 237,707. English Electric Co., Ltd., and Linstow, F. N. July 3, 1924. Oil switches are provided with a cover 8 arranged so that a part 14 of its underside is substantially level with the liquid and gas or air pockets 15 are formed around the points where the insulating tubes 21, 22 surrounding the terminal rods 1, 2 pass through the cover. The cover 8 is bolted to an inner portion 6 carrying the fixed contacts and operating mechanism, the central part of the portion forming an air or gas cushioning chamber 1, 8 communicating by perforations in side plates 16, 17 to the pockets 15 and having an upper outlet 20 leading to a vent pipe 25. An inspection opening 19 is provided to enable the chamber 18 to be cleaned. The switch operating rod 13 passes down through the chamber 18 and is connected by an insulator 12 to the movable bar 11 bridging the fixed' contacts 9, 10. When the switch is opened a considerable pressure is created in the tank so that a quick rupture of the arcs ensues, but this pressure is quickly relieved by the escape of hot gas through the holes in plates 16, 17, the compressed gas being rapidly cooled by acquiring velocity during discharge and coming into contact with the cool parts of the cover. The gas can then exhaust into the atmosphere through the pipe 25, any oil which has been ejected draining back through the holes in the plates 16, 17.

Title: Improvements in or relating to voice operated signal transmission circuits
IPC: H04B3/20
Filed: 1931-06-02
Abstract: 379,707. Valve amplifying circuits. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Nebel, C. N.; 900, Lake Street, Newark, New Jersey, and Bjornson, B. G. ; 57, Horatio Street, New York, both in U.S.A.) June 2, 1931, No. 16123. Convention date, June 7, 1930. [Class 40 (v).] In telephone-repeater echosuppressing means, the voiceoperated control means associated with the transmitting path comprise a pushpull amplifier 22, an amplifier 23 with a high resistance 80 in its grid circuit causing the tube to saturate quickly for waves above a predetermined minimum, a full-wave rectifier stage 24 with negative biasing sources 81 which render it marginal, and a biasing tube 25. When speech enters the transmitting branch the tubes 23, 24 rapidly reach saturation giving a biasing potential across resistances 27 which disables the receiving amplifiers 13, 14, and through tube 25 and resistance 28 renders the transmitting amplifiers 10, 11 operative. During reception, the control amplifier 22 is rendered inoperative by biasing potential applied over lead 68 from a control circuit 63. In a modification the devices 22, 23, 24 are replaced by an amplifier feeding a gas-filled threeelectrode tube of " trigger type the grid potential of which is normally near to that of ionization so that on the arrival of speech currents a sudden rush of anode current rising almost instantaneously to its maximum value occurs. A high resistance in the anode circuit causes the discharge to cease when speech waves are no longer applied.

Title: A process for the preparation of macromolecular polymethylene terephthalates, and shaped articles made therefrom
IPC: C08G63/688
Filed: 1962-05-01
Abstract: In the manufacture of monomolecular polymethylene terephthalates by effecting ester-interchange between a dialkyl ester of terephthalic acid and a glycol and polycondensing the product, polyesters having a lower crystalline melting point are obtained by adding sulphuric acid to the reaction mixture in an amount up to 0.02% by weight of the dialkyl terephthalate. If the sulphuric acid is used in an amount of 0.004% or more by weight, it is preferably added to the reaction mixture after the ester-interchange but before the polycondensation and after the addition, the reaction mixture may be heated to at least 250 DEG C. under normal or slightly reduced pressure. Specified ester-interchange catalysts are calcium acetate, zinc acetate, manganous acetate and litharge and specified polyesterification catalysts are antimony oxide and litharge Examples describe the manufacture of polyethylene terephthalate from dimethyl terephthalate and ethylene glycol. The polyesters are useful in the manufacture of paper and felt (see Division D1).ALSO:Felts or papers are made by heating felt or paper made from a mixture of special polymethylene terephthalate fibres having a reduced melting point (see Division C3) and other fibres (e.g. normal polyethylene terephthalate) to a temperature between the glass transition temperature and the crystalline melting point of the first-mentioned fibres, whereby an adhesive bond is formed between the special polymethylene terephthalate fibres and the other fibres.  During the heating, the felt or paper may be compressed.  Then the original paper or felt may be passed between hot calender rolls.
