Abstract: 977,830. Revapourising liquefied gases. UNION TANK CAR CO. July 6, 1962 [Nov. 27, 1961], No. 25993/62. Heading F4P. A vaporizer for liquefied gas, e.g. oxygen or nitrogen, comprises a plurality of serpentine pipes 39... 44, the ends of which are connected to a liquefied gas inlet header 35 and a gas outlet header 36, the pipes being disposed within a housing 20 which is open at both ends for convectional flow of atmospheric air therethrough. The vaporizer is used in a pressure build-up system for a liquefied gas storage tank, Fig. 1 (not shown). Secured over the air inlet end of the housing 20 is an expanded metal cover 25. The pipes 39 ... 44 include a section 50 for effecting de-humidification of the air and a main heat-transfer section 51; the pipes in the section 50 are bare and are spaced apart so that frost building up thereon will not impede the passage of the air and the pipes in the section 51 have fins mounted thereon. The pipes are preferably made of copper alloy.

Filed: 1922-09-26
Abstract: 207,652. Lorenzi, E. de. Sept. 26, 1922. Forming electric-lamp bulbs.-In an electric incandescent lamp in which the bulb and cap are formed integrally of the same material and the cap has threads or pins for engaging a screw or bayonet socket, the cap 3, Fig. 1, is formed in the mould 1 as a hollow socket which is closed by a plug 6 carrying the filament leads 8.

Abstract: 532,771. Spark arresters. CONSTRUCTIONAL ENGINEERING CO., Ltd., and WOOD, D. H. Sept. 18, 1939, No. 26039. [Class 25] [Also in Group XII] To prevent emission of glare and flames from a cupola, a chamber 11, Fig. 2, having a cross sectional area greater than that of the cupola 10 is arranged above the cupola and surmounted by a hood 15, 16, 19 supported by members 14 on a conical extension 13 of the chamber. The lower part of the hood is surrounded by a skirt 17, also attached to the extension 13. Water or other liquid is delivered on to the top of the hood and passes down the portion 15 between bar 21 or in channels and through an annular space formed between the overlapping portions 15, 19 of the hood to provide a liquid curtain through which the gases &c. from the cupola pass before escaping to the atmosphere. Instead of liquid a gas such as carbon dioxide may be employed to form the curtain. The gases may be cooled in the chamber 11 by air which may enter through an annular space provided between the chamber and the cupola. The water or liquid falls into a trough 24 and then flows down the wall of the chamber 11, which may be provided externally with shield plates 218 to prevent the water being blown off the wall of the chamber, by the wind. The water finally falls into a trough 26 provided with a drain pipe. A baffle 22 serves to direct the gases from the cupola into the outlet passage between the extension 13 and, the hood. Fig. 5 shows a modification applied to a cupola of the kind described in Specification 358,267, [Group XII]. In this case the skirt 38 is supported by a water trough 40.

Abstract: 1,052,954. Coated films. B. X. PLASTICS Ltd. May 10, 1963 [May 25, 1962], No. 26928/ 66. Divided out of 1,052,953. Heading B2E. [Also in Division B5] Two oriented isotactic polypropylene film surfaces are sealed by applying a pressure sensitive adhesive to each of the surfaces and thereafter pressing the surfaces together. The adhesive may be a "cold seal" selfadhesive which gives a good joint at room temperature. The seal may be formed at a higher temperature provided that it is less thanthe temperature at which shrinkage or deterioration of the film takes place. The adhesive is applied by a brush or roller or by an air knife technique. The seal may be formed by a crimp wheel. The adhesive may comprise natural rubber latex or polyisobutylene. The adhesive may also comprise a thickening agent, an antioxidant, a wetting agent, a foam suppressor, an alkali sufficient to produce a pH of 9.5-10.0 and tackifying resins. Suitable thickening agents are alginates, soluble cellulose derivatives, e.g. carboxymethylcellulose and methyl cellulose, casein, ethylene oxide polymers and water soluble acrylates. Suitable, tackifying resins are terpene resins, coumarone-indene resins, natural resin and hydrogenated resin. Antiblocking agents such as polyethylene, and paraffin wax, may be aded to reduce tack. Tack of the adhesive may also be further controlled by the addition of addition polymer emulsions such as vinyl acetate/ethyl acrylate; styrene/ butadiene; and styrene/methyl methacrylate polymer emulsions. Examples are given in which the following substances are also mentioned as ingredients of the adhesive compositions: ammonium hydroxide, a styrenated phenol, sodium di octyl sulphosuccinate, an aliphatic alcohol as antifoaming agent, borax, sodium orthophenyl phenate, a styrene/methyl methachrylate/ethyl acrylate terpolymer emulsion containing 10% of a polythene wax, a petroleum/paraffin wax emulsion, hydrated calcium silicate and toluene. The film surfaces may be treated by a corona discharge before the adhesive is applied thereto to increase the adhesion. Alternatively the film surfaces may be pre-coated with a keying coat, e.g. graft polymers of natural rubber and copolymerisable compounds such as methyl methacrylate, rubbery butadiene/ acrylonitrile copolymers and polyisobutylene.

IPC: E02D5/50
Filed: 1926-10-29
Abstract: 289,495. British Steel Piling Co., Ltd., and Hiley, A. Oct. 29, 1926. Piles.-In the construction of concrete piles according to the method described in Specification 197,430. a pilot pile is driven by means of a tube until a firm stratum is reached and plastic concrete is poured into the tube and deposited and tamped in the hole on top of the pilot pile by vibratory movements imparted to the tube by upward and downward strokes of the hammer. The pilot pile may be precast, but is preferably constructed in the ground by the same method and then, after setting, driven to the described depth by the empty tube. The pilot pile A,Fig. 4, is constructed in situ by vertical vibratory movements imparted to a tube filled with plastic concrete, as described in Specification 197,430. The top of the pilot pile is located at a short distance below the surface of the ground, reinforcing members being carried above the top to bond with the main pile. When the concrete is set, a steel band C is placed in position and filled with plastic concrete, and a steel driving rim D placed in position within the band C. A two-part mould E, Fig. 7, preferably of tapering form, is placed resting on the rim D and filled with concrete. Metal rods E<2> are inserted through holes in the mould E and remain in the head of the pile. When the concrete is set the mould is removed, and blocks of wood E<3> are secured to the head of the pile by means of the rods E<2>. The driving tube B fits loosely over the blocks E<3> and bears on the rim D. The pilot pile is driven by means of the tube B until a firm stratum is reached. Concrete is poured into the tube B, and the latter withdrawn while being given vertical vibratory movements to consolidate the concrete to form the main pile F, Fig. 3. A metal shoe A' is provided at the bottom of the pilot pile A. When a pre-cast pilot pile is used it is provided with the band C, the driving rim D and the blocks E<3> as before. The pile F and the pilot pile A may be driven deeper if required, and a third pile section constructed as before described above the pile F. In soft ground, the pilot pile may be deposited inside a casing surrounding the tube B which can be withdrawn freely within it.
