Title: The treatment of gaseous mixtures
IPC: H01M8/04
Filed: 1968-12-16
Abstract: 1,243,080. Gas separation. SIEMENS A.G. 16 Dec., 1968 [15 Dec., 1967], No. 59766/68. Heading C1A. [Also in Divisions B1 and H1] A method of separating one constituent of a gaseous mixture which has resulted from a chemical reaction from a second constituent thereof, comprises supplying the mixture to a liquid ring pump (described in Specification 1,223,610 as having a rotor supporting a number of vanes, disposed in a housing thereby to define a plurality of chambers between the housing and rotor for receiving pump liquid, and first discharge means at the housing wall, and second discharge means at the rotor) having a pump liquid not capable of absorbing the said one constituent, but capable of absorbing the second constituent, ejecting the first constituent from the pump via the second discharge means thereof, thus affecting separation, and then desorbing the second constituent from the pump liquid and returning the regenerated pump liquid to the pump. With reference to Fig. 2, in the specific disclosure, hydrogen and carbon dioxide, produced by the catalytic reaction in vessel 15 between methanol and water which have been evaporated in a heat exchanger evaporator 14, are passed via pipe 16 and heat exchanger 14, to the liquid ring pump 17, where the carbon dioxide is absorbed in aqueous potassium dimethylamino-acetate, to form potassium hydrogen carbonate and dimethylamino-acetic acid. Hydrogen is released and may be used to feed a fuel cell 34 (Fig. 3, not shown), for heating purposes. The CO 2  containing pump liquid passes via pipe 19 and a preheater 20, to a regeneration vessel 21, heated by a heating circuit 27, 28, 29. Here, CO 2  is evolved, together with some steam, both of which pass up pipe 23 to heat exchanger 14 where the pump water is condensed and passes back to pump 17 via a valve 25 and pipe 26, and CO 2  is emitted at 24. The regenerated pump liquid leaves the regenerator 21 by pipe 22 and is also returned to pump 17 via the heat exchanger 14, where it is cooled. A heating means 28 and heating circuit 27, using a heating medium of "Diphyl" (Registered Trade Mark), is incorporated to provide heat for the reactor 15 and the regenerator 21.

Title: Multistage lift
IPC: B66F3/28
Filed: 1970-12-21
Abstract: 1330647 Platform elevators S W BUSHNELL Jnr 21 Dec 1970 [30 Dec 1969] 60642/70 Heading B8H [Also in Division F1] A working platform 2 is supported on three telescopic multi-stage rams 4 each stage being arranged to be extended sequentially, the cylinders below an intermediate cylinder, which is provided with a valve, being extended by fluid pressure supplied from below and the upper cylinders then being supplied with fluid pressure from above. As shown in Fig. 9, to raise the platform, fluid from a source such as a compressed-gas bottle is directed through a valve 106 on the platform to the base of each ram to raise, first, cylinder 130 and then cylinders 132, 134. When the fluid pressure begins to rasie the cylinder above cylinder 134, this will close valve 136 in cylinder 134, thereby preventing the flow of pressure fluid to the upper portions of the ram. The pressure in the lower cylinders is then increased to increase the rigidity of the structure. The valve 108 is then opened to supply fluid pressure to the upper cylinders to extend them sequentially. The pressure differential between the upper and lower portions of the ram may be achieved by providing a restrictive valve in the top inlet to the ram to allow simultaneous flow to the top and bottom of the ram. In a modification, Figs. 6-8 (not shown), the apparatus is mounted on wheels and the platform 2 is replaced by a bucket suspended from an upper rim on the bucket. The bucket is located between the rams and is provided with a sliding door.

Title: Record player having selective stylus translation facility
IPC: G11B3/09
Filed: 1979-02-12
Abstract: A video disc player stylus is lifted or lowered in relation to a carriage 104 used to carry the stylus horizontally by using a two-position thumbwheel 252. Normal playback drives carriage 104 radially of the turntable 26 in one direction in synchronism with its rotations. For search or special effects operation the stylus remains lowered but the radial movement of carriage 104 is now manually controllable in either direction using another thumbwheel 160. A three-position toggle switch 134 couples the carriage either to a search/special effects belt 132 manually rotated by thumbwheel 160, or to a normal drive belt 130, or the toggle switch can disengage the carriage from either belt. An alternative uses a permanently engaged special effects thumbwheel, and a clutch engaged normal playback motor, so that the special effects thumbwheel rotates during normal playback and indicates which part of a record is playing at any moment. <IMAGE>
