Patent GB-1047884-A (GB)
Title: Improvements in or relating to gas washing processes
Inventor: VINS LUDEK
IPC: C01B3/50
Filed: 1963-06-11
Abstract: In a gas washing process, the impure gas stream is cooled indirectly in a heat exchanging means arranged within the washing tower by a washing medium consisting of a liquefied gas, before said impure gas or said washing liquid enters the washing zone, said washing medium being partially evaporated as it passes through the washing tower in counter current to the impure gas stream to strip the impure gas stream of its impurities by liquefaction.  A mixture of washing medium and liquefied impurities is withdrawn from the bottom of the washing tower.  In a particular embodiment, the impure gas is hydrogen contaminated with carbon monoxide, and the washing liquid is nitrogen; the carbon monoxide is removed from the hydrogen and the resultant evaporation of nitrogen produces a gaseous mixture suitable for the synthesis of ammonia.  An apparatus suitable for performing the process comprises a washing tower, with means for admitting liquefied gas in the top, a coil of piping in the upper part of the tower in which impure gas prior to entering the base of the tower is cooled indirectly by the said washing medium; means for extracting the pure gas from the top of the washing tower and means for removing the contaminated washing medium from the bottom of the tower.  A further coil of piping may be arranged in the top of the tower, through which coil, the washing medium is passed before being admitted at the top of the tower.

Filed: 1947-08-21
Abstract: 626,269. Heating water. GODDARD, H. G. Aug. 21, 1947, No. 23208. [Classes 64(i) and 64(iii)] In a domestic hot-water supply system, water in a tank 3 in series with a coldwater supply and a heating apparatus is pre-heated by hot waste water diverted into an insulated container 1 surrounding the tank by a thermostatically controlled valve 15 in a conduit 12, which receives hot water discharged by one or more waste pipes and communicates at 6 with the bottom of the container 1, the valve 15 discharging 'the waste water, when it has cooled to a pre-determined temperature, to the drainage system. When the valve 15 is closed, excess waste water can escape through the pipes 7, 8. When the water has been discharged from the container 1, the air which takes its place acts as an additional insulator for the tank 3.

Abstract: 1294604 Ion pumps ENGLISH ELECTRIC VALVE CO Ltd 19 April 1971 [15 May 1970] 23619/70 Heading H1D An evacuated electron discharge tube apparatus comprises an electron discharge tube and an ion getter pumping device including a body 3 of radio-active material arranged to act as a source of power therefor, said device being either within a vacuum tight housing constituted by the envelope of the tube or within a vacuum tight housing which includes the tube envelope, an envelope for said device and a communication channel between them. The pumping device comprises a glass support 1 through which are sealed pins 7 supporting a cathode 2, a pin 8 supporting a backing plate 4 for the body 3, and a pin 9 supporting a particle receiver 5, anode 6, end a sputter shield 10. One pin 7 is connected directly to pin 8 which is connected to pin 9 through a resistor 11 e.g. of 10<SP>11</SP> ohms. At least the inner surface of cathode 2 is made of getter material, e.g. Ta or Zr or, preferably, Ti. The receiver 5 and anode 6 are also made of getter material. The plate 4 may be of Al and the shield 10 of Mo. The body 3 is preferably an α-particle emitter, e.g. Po 210 , Cm 242  or Am 241 , and may be shielded by thin steel plates (not shown), to reduce the X-ray count. Alternatively the radio-active material may be a #-emitter, e.g. H 3  absorbed in Ta, in which case the parts 5 and 3 must be interchanged. The pump combines three effects-chemical pumping by the getter material and collection of ions produced by the radio-active material and by electrons produced as a result of this ionization. An alternative embodiment (Figs. 3 and 4, not shown) comprises a glass base supporting a coaxial arrangement of an anode surrounded by two grids and a cylinder with an internal film of α-emitting material and two end shields. The inner grid collects ions and the outer grid collects α particles. The film may alternatively be of #-emitting material, in which case only one grid is necessary. In either arrangement electrons orbit around the central anode. The electron discharge tube may be a high power microwave tube.
