Title: A process and an apparatus for purifying gas by oxidation and reduction
IPC: B01D53/34
Filed: 1964-03-20
Abstract: <PICT:1043115/C1/1> In purifying a gas by oxidation and reduction, for example from oxygen, carbon monoxide and hydrogen impurities, the gas is passed at a temperature of from 150 DEG  to 800 DEG  C. through a filter bed containing particles comprised of copper and particles comprised of copper oxide, a zone of the bed being regenerated, during passage of the gas through the bed, by passing oxygen, carbon monoxide or hydrogen, in gaseous form, through the zone. Preferably, a sample of the gas which has passed through the zone is tested with a gas-testing instrument which controls the supply of oxygen, carbon monoxide or hydrogen to the zone so that carbon monoxide or hydrogen is supplied to the zone if there is undesired oxygen in the sample, and oxygen is supplied to the zone if there is undesired carbon monoxide or hydrogen in the sample.  The bed may initially comprise a first zone containing copper oxide particles disposed upstream of a second zone of copper particles, the gas passing, at the beginning of the purification process, through the first zone and then through the second zone to remove oxygen from the gas and, during the remainder of the process, through the first zone to remove carbon monoxide or hydrogen from the gas and then through the second zone, gaseous oxygen being meanwhile passed through the first zone to regenerate it.  Apparatus for purifying a gas, for example the inert or noble coolant gas, such as carbon dioxide or helium, in a nuclear reactor, comprises a filter bed containing particles comprised of copper and particles comprised of copper oxide, first duct means for passing the gas through the bed, and second duct means for supplying to a zone of the bed, during passing the gas through the bed, oxygen, carbon monoxide or hydrogen, in gaseous form, to regenerate the zone.  As illustrated in the Figure, container 2 contains a filter bed consisting of two zones, zone 3 containing a mixture of copper- and copper oxide-containing particles, and zone 4 containing only copper particles.  Gas to be purified is supplied by pipe 5 and withdrawn by pipe 6. Gas-withdrawal device 7 conducts a sample of the purified gas to gas-testing instrument 8 which controls regulating valves 81 and 82 which are disposed in pipes 51 and 52, respectively.  Depending on the findings of the instrument, these pipes supply additional gases 9 and 10, which may be carbon monoxide and oxygen, or hydrogen and oxygen, to the gas to be purified. The particles may be porous sintered bodies consisting of copper and/or copper oxide, or ceramic bodies vapour coated with copper and/or copper oxide.

A dental syringe, to which air and water are supplied under pressure to form a spray, has a chamber from which medicament is ejected into the outgoing stream by the pressure of either the air or water. Water and air supply pipes 6, 7 pass to control valves 4, 5, respectively, both actuated by a wheel 2. From the valves they flow through ducts 14, 25 to the mixing nozzle 12 but a branch from the air pipe 25 leads to the space below a piston 21 in a medicament chamber 16 so that medicament is forced out through a duct 20 to the water duct 14. Normally the duct 20 is closed by a needle valve 26 but, when valve 5 is opened air pressure, acting on a diaphragm 28, lifts the stem 26 to open the valve. The degree of opening may be set by a stop screw 34. In a second embodiment the space below the piston is connected to the water supply duct, and the latter contains a choke tube to ensure a suitable fall in pressure for the medicament to leave the chamber.

Abstract: 748,705. Control of several D.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. May 5, 1954 [May 5, 1953], No. 12465/53. Class 38(3) A control system for a vehicle comprises a series-wound traction motor 1 connected in parallel with a shunt-wound motor 8 which drives a generator supplying auxiliary services on the vehicle. If collector shoes 3, 4, are in contact with the conductor rails, a no-volt relay is energized by means of coil 13c, so that closure of switch 14 energizes contactor coil 7c from auxiliary source 11, 12, the circuit for the contactor coil extending through contacts 13a 10d and 6d. contacts 7a, 7b, are thus closed to energize the motor 1 and contacts 7e open to de-energive the coil 13c, the no-volt relay being maintained closed, however', due to its series coil 13b. To start the motor 8, switch 18 is closed to energize relay coil 10c so closing contacts 10a, 10b; contacts 17a are closed since relay coils 17b, 17c, act in the same direction so that opening of contacts 10d does not de-energize the coil 7c. If the collector shoes pass over a gap in the conductor rails, the opening of the no-volt relay is desirable since this relay is normally relied upon to open contacts 6a, 6b, 6c, which shunt sections of resistor 5 in the traction motor circuit, whereby when the supply is restored, the traction motor is protected by the resistor 5. However, motor 8, owing to its inherent inertia, acts as a generator and tends to maintain the energization of the coil 13b. To prevent this, use is made of the reversal of current in the winding 17b when the motor 8 acts as a generator whereby coils 17b, 17c, act in opposition and contacts 17a, so de-energizing coil 7c and opening contacts 7a, 7b. The no-volt relay has a calibrating coil 13d connected in series with an adjustable resistor 16. The resistor 19 in series with coil 17c is also used used for calibration.

Making turbine blades.-A method of making a metal article having one or more internal passages or cavities, particularly a hollow gas turbine blade, comprises forming in a billet or the like one or more holes by electric spark erosion, each hole being of annular or other section such that a core is left inside it, introducing into each hole a filler in the form of an annular sleeve surrounding the core, hot working the filled billet to cause the metal thereof to flow and the size and/or shape of each hole to be changed, and removing the filler. Each hole made in the billet may extend completely therethrough so that the core is freed and is used inside the filler to fill the hole, or preferably the hole extends only part way through the billet to leave a closed end which is removed after the working. The filler may be a preformed metal sleeve inserted into the hole around the core; it is subsequently removed by acid erosion. A gas turbine blade is formed from a billet of given dimensions made of nickel-chromium with small percentages of titanium and aluminium and having closedended holes filled with an alloy of iron, manganese and titanium. The billet is heated and extruded, closed-end first, through a die aperture of air-foil section. The extruded section is then cut into lengths and the filler removed in a bath of boiling acid, the loose cores being then pulled out. Further hot or cold reduction or shaping operations such as hot rolling may then be performed. In the case of cold working, a temporary filler is inserted in the holes. Working at specified temperatures.-The billet is heated to 1,200‹ C. before extrusion.
