Patent GB-1114947-A (GB)
Title: Process and apparatus for drying and/or purifying gases
IPC: F25J3/02
Filed: 1966-05-10
Abstract: Gas mixtures containing high concentrations (i.e. >1%) of condensible impurities are purified by cooling on heat exchange surfaces, pairs of such surfaces being operated alternately so that while one is being used to cool the gas mixture, deposited impurities are being re-evaporated from the other, e.g. by the passage of a scavenging gas or by reduction of pressure.  Heat transfer is restricted in the region where the impurity content of the gas mixture is greatest by keeping the temperature difference between pairs of surfaces low, or by using an exchanger construction in which the surfaces are separated from each other by a gaseous medium which is continuously circulated through the apparatus.  In a preferred embodiment (see Fig., not shown), gas from which condensibles are to be removed passes by line (8), heat exchangers (9, 10) and water separator (11) to cross-counterflow heat exchangers (12-15).  Each comprises a plurality of tubes, of which half are supplied with the gas to be purified, and the other half with the scavenging gas in counterflow, and valve arrangements permitting the interchange of the gas supplies between the two sets.  Gas is also supplied to the space between the tubes.  The velocity of the scavenging gas decreases in counterflow to the gas being treated.  A plurality of such exchangers are used in series in the removal of moisture, CO and CO2 from a high pressure H2 supply used in preparation of synthesis gas for NH3 production, the scavenging gas being an N2-CO mixture obtained by the subsequent final purification of the H2 by treatment with liquid N2 obtained from liquefaction of air.  In another application, CO2 and H2S are removed from gas mixtures.

Abstract: 141,406. Temple, R. Dec. 13, 1918. Sunken ships, raising and moving. - An apparatus particularly designed for salving sunken ships comprises means for driving a special projectile, by means of an explosive charge, into the hull of the ship in such manner as to remain embedded therein. The projectiles may be specially formed for the attachment of ropes or floats &c., or may pass through a patch as well as the hull, thus securing the patch in position. A hand tool comprises a short barrel a, Fig. 1, with an extension o of reduced diameter shouldered at o<1> and held in position, together with an annulus or disk p of material such as tough copper, by a union q. Access of water to the interior of the barrel is prevented by disks q<1> and h. At the breech end the barrel is closed by a block e seated in a copper ring g by a screwed plug i bearing on the disk h and apertured to pass the firing-pin j. The detonator f is exploded without perforating the disk h. The projectile comprises two parts, the nail-like portion b, preferably fluted, that penetrates the hull, and a light portion b<1> that serves to contain the propellant and is arrested by the ring p and shoulder o<1> thus minimizing recoil. The part b has a light screwed or similar connexion with the part b<1>, the thread being stripped when the part b<1> is arrested as shown in Fig. 2. The screw d extends through the part b<1> into the block e and is reduced at c<1> to en extent sufficient to permit fracture after the explosion pressure has risen considerably. The plug i serves also for the attachment of a firing handle, that may be used for a series of barrels, by means of a tapped sleeve l provided with a projection l<1> sliding in a groove in the holder k. The firing-pin is depressed by hand against the action of a spring n and premature action is prevented by a catch m. In modifications, a number of gun units may be secured to a base that may be secured to the ship's side and the charges may be fired electrically. The gun may be fired from its front end, a detachable nose or cover being soldered or otherwise connected to the muzzle end of the barrel and provided centrally with a rim percussion fuse. The front of the projectile has a wrapping of gun cotton to provide a flash for transmission through a firing-hole to the propellant at the rear. The nose or cover is attached to the hull by the projectile and serves for attachment of the float &c. The cover may be integral with the barrel that is necked at the desired point for fracture.

Abstract: 758,782. Electromagnetic relays. WESTINGHOUSE AIR BRAKE CO. July 20,1954 [July 24, 1953], No. 21086/54. Class 38(5) A relay similar in many respects to that disclosed in Specification 708,985 comprises a magnetic shell 2 surrounding a core 7 and winding 8, a four-armed armature 16 having a spindle 18 being pivoted on the core, the armature arms 22 co-operating with pole pieces 13 carried by a non-magnetic plate 10. The shell 2 together with a disc 3 welded thereto forms a sealed enclosure, contactcarrying posts 5 being mounted in glass beads 4 in the disc. An insulating contactactuating spider 17 secured to the armature hub 21 has six notches 28 formed in its upstanding peripheral wall 25 which engage the extremities of respective spring contact fingers 33 having contacts 37, 38. When the coil 8 is not energized the bias in the fingers 33 holds the contacts 37 against back contacts 31, energization of the coil causing the ends of the notches 28 to flex the fingers so that contacts 38 engage front contacts 32, this engagement taking place before the arms 22 engage the pole pieces 13. To prevent rebound of the armature on back stops 12 when the coil is de-energized the spider 17 has a peripheral groove 29 frictionally engaged by a resilient inertia ring 30 whereby when the armature is arrested by the stops 12, the ring 30 continues to rotate and exerts a force on the spider to hold the armature against the stops. The ends of the fingers 33 are bifurcated and of unequal length, the longer upper tips 35 co-operating with the notches 28. To allow for contact misalignment the surfaces of the contacts 31, 32 are arcuate about an axis at right angles to that about which the surfaces of contacts 37, 38 are arcuate.

A liquid measuring and dispensing device, e.g. for metering oil in a domestic supply, comprises a tank 20 containing a quantity of a liquid, e.g. water with added electrolyte, having a higher electrical conductivity and specific gravity than the liquid to be dispensed. In operation, the oil is fed under pressure into the lower chamber 21 of tank 20 via pipe 24 and forces the water into the upper chamber 11 via pipe 22 thereby displacing oil already in chamber 11 via chamber 18 and delivery pipe 19. When the water level reaches an electrode 31 a circuit is energized, via electrodes 32, 33 and a relay, to open a valve 14, thereby permitting flow of oil through pipe 12 from chamber 21 into chamber 11 and through pipe 19, the water in chamber 11 flowing back through pipe 22 into chamber 21. When the water level falls below electrodes 32 and 33, valve 14 is closed and the cycle repeated. A counter in the valve control circuit records the number of cycles. In a supply system a number of the devices are fed from a common, constant pressure oil supply comprising a tank with an air space fed with oil by an electric pump controlled by a pressure switch in the air space.

Abstract: 772,231. Rectifiers; glass to metal seals. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 18, 1953 [Aug. 26, 1952], No. 21427/52. Classes 36 and 37. An electric circuit element such as a crystal diode or thermistor is enclosed in a glass tubular envelope, and the glass at the region where the final seal is made to a lead-in conductor, is thicker than the wall of the tube, so as to resist the expansive effect of the trapped air in the envelope. In Fig. 3, the lead-in wire 7 of electrode 6 is sealed in one end of a glass tube 1. Crystal 3 is supported on lead-in wire 5 which is surrounded by a thick glass tube portion 8. Heat is applied to seal tube 8 to tube 1, and wire 5 to tube 8. The additional strength provided by tube 8 prevents the glass, even when plastic, from being deformed by the pressure due to expansion of the air in the cavity. To avoid heat damage to the crystal, the lead-in wires may consist of a low heat conductivity alloy such as iron-nickel cobalt, or iron-nickel, which may be partly copper coated, and borated or glass covered to aid sealing. A getter may be included in the assembly.
