Title: Process for producing a mixture of carbon monoxide and hydrogen suitable for the synthesis of hydro-carbons
IPC: C22C1/04
Filed: 1936-07-03
Abstract: 466,737. Water-gas plant. KOPPERS' INDUSTRIEELE MAATSCHAPPIJ N.V., H. July 3, 1936, Nos. 18496, 18497, and 18498. Convention dates, July 3, 1935, Aug. 2, 1935, and Aug. 2, 1935. [Class 55 (i)] In the production of a gas mixture of hydrogen and carbon monoxide, preferably in the proportion of 2 : 1, suitable for the Fischer - Tropsch syntheses, by passing a mixture of coal distillation gas and steam through the hot bed of a water gas generator 1, the mixture of gases is preheated in a regenerator 15, previously heated to a high temperature by the " blow " gases from the generator, before entering the latter, so as to ensure a substantial conversion of the hydrocarbons in the coal gas before contacting with the hot fuel bed. The temperature of the " blow gases is increased by the introduction of secondary air through air inlets 8 arranged in the gas space 7 of the generator. Alternate inlets 40 may be supplied with fuel gas, such as coal or producer gas, to ensure complete combustion of the blow gases. The inlets 8 and 40 may alternatively, or in addition, be arranged in the circumference of the connecting pipe 13 between the generator and regenerator. This latter pipe may also take the form of a venturi to ensure thorough mixing of the gases. The blast is followed by a purging with wet steam, which also causes granulation of the molten slag. The chimney valve 17 is then closed and the mixed gases for the " run " supplied to the base of the regenerator where they are heated to 1000‹ C. The resulting gas mixture withdrawn through the slots of the cap 3<a> of the revolving grate 3 of the producer, is separated from dust in the main 24 before passing to the scrubber 26. A further steam purge is made before re-commencing the cycle. The " run " period may be extended to 4-5 minutes, the " blow " occupying 1 minute. Catalysts may be provided on the checkerwork of the regenerator, such as iron oxide, or the bricks composing the same may be impregnated with suspensions of catalysts before or after the bricks are made. Excessive air in the blast ensures regeneration of the substance employed.

Title: Improvements in electric switches with compressed-gas blow-out
IPC: H01H33/70
Filed: 1935-06-28
Abstract: 463,619. Fluid -- blast switches. MARX, E. June 28, 1935, No. 18547. Convention date, June 29, 1934. [Class 38 (v)] A switch of the type in which the break-arc is extinguished by a gasblast and having oppositely-arranged apertured switch electrodes and main switch electrodes arranged behind the apertured electrodes, has' the latter serving mainly as electrical screens and the adjacent surfaces of each main and associated screen electrode so spaced and shaped that an area of low gas-velocity is set up in front of the main electrodes whilst the stream issuing from the aperture in the screen electrode is substantially deflected radially. The drawing shows, in the open position, a switch having two oppositely-arranged electrode systems of different construction, the screen electrodes 1, 2 surrounding the main electrodes 3, 4 and being provided with apertures 5, 6, the length b of which equals, or exceeds, the diameter d. The arrows show the blast directions, and the spaces 7, 8 show the regions of low velocity, which regions are enlarged by incurving the electrodes 3, 4 at 9, 10. The Specification gives an expression relating the electrodes separation a with the arc-chamber pressure and reverse break-down voltage. Each screen electrode may be made resilient adjacent the aperture, so that the latter may adjust itself to the gaspressure or to the pressure of a resilient contact engaging therewith. The main electrodes may serve as contact-making elements, the spacings then being those of the elements in the open position. The main and screen electrodes may be arranged so that one or other form main and auxiliary contact-making members, and the screen electrodes may be kept at a different potential from that of the main electrodes. Reference has been directed by the Comptroller to Specification 458,101.

Abstract: 403,455. Code telegraphy. FULD & CO. TELEPHON-UND TELEGRAPHENWERKE AKT.-GES., H., 136, Mainzerland-strasse, Frankfort-on-Main, Germany. July 6, 1932, No. 19114. Convention date, July 8, 1931. [Class 40 (iii).] In motor-driven impulse-transmitters or receivers, such as are used for telegraph printers, electric telewriters and the like, the driving motor is connected directly to alternating-current mains, and a stationary rectifying device is provided as a local source for supplying the signalling current, the rectification taking place only after multiplication of the frequency of the mains current by electro-magnetic conversion of the individual half-waves of the alternating current into full alternating waves by means of transformers. In the example the transmitting contact S E is driven intermittently by a driving- motor which can be connected to the mains N through a plug and socket and is used to drive the receiving devices, (not shown) controlled by an electromagnet E M, when the apparatus is used as a receiver. The motor-speed is adjusted and regulated by resistances R<2>, R<3> and a centrifugally operated contact K. Preferably a fifty-cycle alternating voltage is supplied from an auto-transformer S T to two transformers T<1>, T<2> with primary windings P<1>, P<2> which receive a half-wave of the fifty-cycle main current through dry rectifiers Z<1>, Z<2> connected thereto. The secondary windings S<1>, S<2> connected in opposition produce a current of 100 periods per second which is rectified in a full-wave rectifying- device comprising rectifiers Z<3> .. Z<6>. Smoothing is effected by a filter circuit comprising a choke coil D and condensers C<1>, C<2>, and the rectified current is regulated by a resistance R. An iron-hydrogen resistance E R is provided to neutralise automatically the effect of voltage peaks from the mains N. The arrangement may be modified for double-current operation.
