Abstract: 588,758. Valve circuits. ELECTRIC FURNACE CO., Ltd., and KING, S. G. May 8, 1944, Nos. 15937/4.5 (divided out of 588,714) and 15908/44. [Class 40 (v)] [Also in Group XXXV] In a control system for reducing fluctuations across a pair-of load terminals due to variations in the A.C. supply, a valve is controlled in accordance with the variations to alter the current through a control winding of a choke, thus changing its reactance, the main winding of the choke being connected between the supply and load. The circuit is described as applied to a valve oscillator A, the heater transformer D of which is supplied through the main winding F1 of a choke. A bridge H of lamps and resistors connected to the supply, feeds a voltage to potentiometer J<2>, a portion of this voltage, together with a voltage from potentiometer K<2> being rectified and applied to valve G to vary the current in the control winding F2 of the choke. The cathode current of valve A passes through a second control winding F3 to reduce the filament current when the load on the oscillator is reduced. A third winding F4 provides a manual control, the indirectly heated rectifier M providing a delay when the apparatus is switched on. In a modification, Fig. 2 (not shown), a single control winding is used on the choke, the voltage applied to the grid of the valve being the resultant of voltages dependent on the supply and the load potentials together with a steady D.C. To correct for changes in voltage due to frequency changes in the supply, the transformer supplying the potential dependent on the supply voltage may be fed through a frequency-sensitive divider comprising a condenser and resistance in series. -

Abstract: 1472595 Catalytic shift reaction SHELL INTERNATIONALE RESEARCH MAATSHAPPIJ BV 11 April 1974 [17 April 1973] 16149/74 Heading C5E [Also in Division B1] In a process for the production of a hydrogen rich gas by the conversion of a carbon monoxide containing gas with steam, poisoning of the catalyst by sulphur compounds present in the feed gas is avoided by using a sulphidic conversion catalyst which comprises nickel and/or cobalt, and molybdenum, and 0À1-1À0 part by weight of aluminium per part by weight of nickel and/or cobalt on alumina as carrier, which catalyst is prepared by impregnating the carrier with one or more solutions of compounds of nickel and/or cobalt and of molybdenum and aluminium, at least 40% by weight of the aluminium being supported on the carrier by coimpregnation with the nickel and/or cobalt. The catalyst, after drying and calcining, is converted to a sulphidic form by heating in a mixture of hydrogen, steam, and hydrogen sulphide. To ensure that the catalyst remains in sulphidic form during the carbon monoxide conversion, the feed gas preferably comprises at least 10 p.p.m.v. sulphur, and this may be present as hydrogen sulphide added to the feed gas if the feed gas does not already contain the desired amount of sulphur. The catalyst is suitable for use in both high and low temperature conversions (175-425 C.) but if a multistage conversion is used, a conventional high temperature catalyst (iron-chromium) may be used above 300 C., and the catalyst of the invention for the low temperature conversion.

Bore-hole apparatus. - Pipes are laid without previous excavation by passing water under pressure through a plunger and the pipes to wash away and soften the soil in front of them, the water simultaneously acting on the plunger to press the pipes longitudinally into the soil. A hydraulic cylinder 1, with direction-sighting means, contains a plunger 10 with a neck 9; a pipe 2, provided with a nozzle 6, is engaged with the neck 9 and guided in a divided front cover 7. Water admitted through a pipe 11 passes through the pipe 2 and nozzle 6 to wash away and soften the soil and also acts on the plunger to force the pipe forwardly; a further pipe 2 is then placed between the plunger 10 and the first pipe and the operation is repeated. During this operation, the pipes may be rotated by hand or by mechanical means. Water may be admitted through a pipe 13 to the front of the cylinder 1 to control the advance of. or to return, the pipes. Pipes not adapted to withstand longitudinal pressure may be enclosed in metal pipes which are then driven as above; the metal pipes are then withdrawn, and during such withdrawal the inner pipes are forced out of the metal pipes by the use of a small pipe between the rear of the inner pipes and the rear cover of the cylinder 1.
