Abstract: 864,973. Conduits. CONCH INTERNATIONAL METHANE Ltd. June 29, 1959 [July 2, 1958 (2)], No. 22304/59. Class 33. A conduit for the transmission of cold liquids is formed from elongated segments 10, Fig. 1, in end-to-end and side-by-side relationship with means sealingly joining their abutting edges and longitudinally-spaced restraining bands holding the assembled segments, the inner conduit wall 16 being of material strong and ductile at low temperature, e.g. hardwood, the outer wall 18 being of a weatherresistant material, such as hardwood, a thermal-insulating material, e.g. a highly porous low-density wood being therebetween. The means joining the said edges comprise aligned corresponding slots 24 splines 26 extending between the edges in the slots 24. The slots may be formed in edge sections of hardwood strips extending inwardly less than the thickness of the strips to receive the splines 26 which may be elongated wooden members. The bands may be metal or fibre glass 32 impregnated or coated with a curable liquid resinous material. In Fig. 5 stainless steel restraining bands 120 are shown around assembled segments (which may be hardwood), as an inner wall and inside thermal insulation. Reinforcing circumferentially-spaced ribs 124 may then be along the length of the conduit 110, intervening pockets 126 receiving the insulation. An outer skin is desirably wrapped around the conduit and may be aluminium or stainless steel. The segments may be curvilinear or be flat panels, Fig. 3, the conduit 40 being of rectangular cross-section with edges joined by tie rods 54 extending crosswise through openings in the edge portions of the panels 42, 48 and through the panels 44, 46 and nuts or like other means 56 threaded on to the tie-rod ends to hold the panels 42, 48 in tension. The panels have inner and outer walls 60, 58 of hardwood, which may be covered with a metal sheet or plastic film, edge strips 62 being also of hardwood with slots 50 in the panels 42, 48 to receive keys 52 on the panels 44, 46. The segments may be staggered endto-end so that only one abutting joint occurs in any cross-section of the conduit.

July 24, 1930, No. 22354. [Classes 83 (i), 83 (iii), and 83 (iv).] Casting processes ; moulds; forging-dies.-In making a cutting tool for machining metals, drilling wells &c., a tip of an alloy of cobalt with one or more metals of the chromium group, such as chromium, tungsten, molyb. denum, uranium, is welded to the shank by applying it thereto in a plastic state and applying pressure while maintaining it wholly confined within a space defined by the cutter portion and rigid forming walls. The tip is thus welded and forged to the desired shape. The portion of the shank to be tipped may be arranged in a die and the alloy deposited thereon by arc or drip welding. The alloy when at a bright orange or white heat is then compressed by a co-operating die which operates to confine the alloy completely in the dies and to forge it to the configuration thereof. The shank 3 may first be inserted in a lower die 1, the alloy 4 then applied and the forging effected by a hydraulically operated die 2. The lower section of the die may form part of the die set for forging the shank, and the upper die may be actuated by screw-operated apparatus, power press or drop hammer.

A hose connector in a static vacuum cleaner installation comprises a socket fitting to receive the end of a hose connector spigot, a valve to control the passage of air from the vacuum cleaner pipe line to the hose, means to secure the hose in the connector to permit rotational but not longitudinal movement of the hose, and means to prevent opening of the valve until the hose is located in the connector. The end of the hose 7, on insertion through an opening 6 in the connector box 2, releases a spring loaded catch 16, engaging in a slit in a flap valve 10, thus permitting the flap valve 10 to be opened. The flap valve 10 is mounted on a pivotal part 11 to cover and uncover an opening 4 connected by a pipe to a vacuum pump. A locking member 13, with a semi-circular recess 14, pivots about a post 13a (not shown) and is adapted to engage in a circumferential slot in the end of the hose 7 to lock the latter in position. An arm 17 enables the locking member 13 and the flap valve 10 to be simultaneously moved to uncover the opening 4. Alternatively the flap valve 10 may be replaced by a rotary sleeve valve 19 (not shown) and the hose 7 held in the socket by a flange 25 (not shown).

Patent GB-987341-A (GB)
Title: Improvements in or relating to the preparation of copolyesters
IPC: C08G63/40
Filed: 1963-06-07
Abstract: In a process for making copolyesters by slowly adding an alkaline aqueous solution of bisphenol A to a mixture of terephthaloyl chloride and isophthaloyl chloride dissolved in a solvent which also dissolves the copolyester, improved products are obtained by slowly adding an aqueous alkaline solution of a monohydric phenol to the solution of the acid chlorides simultaneously with the addition of the bisphenol solution. Copolyesters having a favourable molecular weight distribution are obtained if the addition of the monohydric phenol solution is commenced after about 40% of the bisphenol has been added. Catalysts for the reaction are quarternary ammonium and phosphonium compounds.  Specified monohydric phenols are phenol, cresols, xylenols and p-phenylphenol.  In the examples, the acid chlorides were dissolved in methylene chloride and the phenols in aqueous sodium hydroxide solution.  The copolyesters may be extruded or injection moulded.

Filed: 1927-08-30
Abstract: 276,697. I. G. Farbenindustrie Akt.- Ges. Aug. 30, 1926, [Convention date]. Materials, special. - Acid-proof articles are made by applying to a support or core a number of layers of wide meshed fabric, impregnating the fabric before, during, or after its application to the core with a synthetic resin, and subjecting the material to treatment to harden the resin. The article is then stripped from the core. Solid rods or other articles mav be made by winding the fabric upon a core formed of impregnated fabric twisted into a rope. Flanges may be formed by winding further layers of fabric where necessary. The hardening is conducted in a heating oven, for instance, a double-walled pipe heated by steam. A core may be made from fabric impregnated with synthetic resin and may then form part of the finished article. The synthetic resin may be applied to the fabric by soaking the latter prior to winding, or by brushing or spraying during or after winding, and the hardening is generally conducted in stages at increasing temperatures. The manufacture of rod, bolts and nuts is described. In the latter process, a thin rod, or alternatively a piece of twisted and stretched fabric, is wound round with layers of fabric impregnated with bakelite, and the hardening is carried out in a chamber heated by gas jets. The rod may be turned and provided with a screw thread; and similar rod or tube may be planed to hexagonal section, cut into short pieces, drilled and tapped to form nuts.
