Abstract: 573,923. Combustible gas mixtures. STEINSCHLAEGER, M. May 10, 1940, Nos. 8440 and 8441. [Class 55 (ii)] In the production of a gas mixture containing carbon monoxide and hydrogen suitable for use in the Fischer-Tropsch synthesis, coke is heated with at least 150 per cent of the theoretical amount of steam required for the water gas reaction, at a temperature between 900‹ and 1000‹ C., to produce a gas containing more hydrogen and carbon dioxide than is normally present in water gas, and, after removal of the carbon dioxide, the residue is mixed with coke oven gas to produce a gas suitable for use in the Fischer-Tropsch process. This gas mixture is heated in the presence of a cobalt, nickel or iron catalyst at between 160‹ and 250‹ C. to produce oils and gases rich in methane which are in one case heated with steam at between 800‹ and 900‹ C. in the presence of nickel or iron catalyst to produce a gas which, on admixture with water gas, is suitable for use in the Fisoher-Tropsoh process. In the other case, the gases rich in methane are heated with steam between 1120‹ and 1500‹ C. in the absence of a catalyst to produce a gas which is mixed with water gas, and a gas obtained by heating water gas with steam in the presence of a catalyst at between 400‹ and 500‹ C., and then separating carbon dioxide, to give a gas mixture suitable for the Fischer- Tropsch process. The cobalt, nickel 'or iron catalyst may be activated by thoria. The. gases used in the process should be substantially free of sulphur. Specification 513,778 is referred to.

Title: Improvements in driving gear for use with internal combustion engines
IPC: F01B9/02
Filed: 1928-03-21
Abstract: 313,231. Wintringham, T. H. March 21, 1928. Driving-gear.-A quantity of oil f is interposed between the power piston a and the connecting rod h driving the crank shaft. A plunger e attached to the piston a works in. a tube d<1> and acts on the oil; the connecting rod is attached to the piston g, which may be ot larger diameter than the plunger e so that the piston a may have a long stroke. At the end of the out-stroke the plunger e enters a tube d<3> with a restricted outlet k. The return stroke of the piston is effected by the action of the crank shaft through the piston g and the oil column. To prevent excessive pressure rise in the oil an expansion chamber m is connected to the tube d; a spring- pressed piston in the chamber allows oil to flow from the tube at a determined pressure, the oil returning to the tube when the pressure therin falls. To obtain a delay in the movement of the power piston at the end of the out-stroke, a plunger q is driven by the cam r to vary the volume of the tube d in the required manner. A filler tube l is provided. One power piston may act on several columns of liquid or on one column subdivided.

Title: Improvements in or relating to glow discharge devices
IPC: H01J17/00
Filed: 1956-03-23
Abstract: 789,875. Cold-cathode tubes. WESTERN ELECTRIC CO., Inc. March 23, 1956 [March 24, 1955], No. 9129/56. Class 39(1). A glow discharge tube comprises a molybdenum wire anode 20 supported within a glass envelope 21 by a lead 22. A helically coiled molybdenum wire cathode 24 is welded near one end of a bimetallic strip formed by a molybdenum plate 26 and a nickel plate 27, the other end of which is welded to a support lead 28. The tube is operated at a point away from the Paschen minimum of the breakdown voltage-pressure x distance curve, and changes in gas density in the discharge gap due to localized heating of the cathode by the discharge are compensated by the bimetallic strip which increases the anode-cathode spacing so that the breakdown voltage remains constant. The anode-cathode spacing may be adjusted initially by etching the end of the anode by positive ion bombardment as described in Specification 789,876 and the spacing, shape of the cathode and gas pressure are preferably chosen to attain a stable negative resistance characteristic as described in Specification 686,427, which also discloses alternative forms of cathodes which may be used. A preferred gas filling is neon at 100 mm. pressure. If the tube is to be operated under conditions of severe ambient temperature variations, the anode may also be mounted on a bimetallic strip so that changes in the ambient temperature will not affect the anode-cathode spacing. The tube is suitable for use in the telephone switching networks described in Specification 704,108 [Group XXXIX].
