Title: Process for the production of aliphatic ketones
IPC: C07C45/74
Filed: 1941-04-11
Abstract: In the production of unsaturated ketones by the auto-condensation of ketones under the action of calcium carbide, the initial ketone is acted upon by 5-50 per cent of a molecular quantity of calcium carbide and the product is removed quickly from the reaction zone. The reaction may be effected in apparatus of the Soxhlet extractor type, or the ketone may be passed over the calcium carbide at slightly above its boiling point but below the boiling point of the product.  In examples acetone and methyl-ethyl ketone are treated in a Soxhlet apparatus, the products being mesityl oxide and 5-methyl heptene-4-one-3 respectively.  Specification 525,142 is referred to.

Patent GB-1084766-A (GB)
Title: Improvements in or relating to the manufacture of bristle-surface products
IPC: A46B15/00
Filed: 1965-02-04
Abstract: A bristle-surface product is made by sewing a synthetic resin fibre-length or filament to a flexible backing member to form a series of loops standing proud of the backing surface, and then cutting or otherwise opening the loops to form the bristle elements. Preferably, the relative strengths of the filament and backing are approximately in the ratio of 1:3.  The backing may be a synthetic resin, a textile fabric or rubber and may be perforated.  If the backing is a synthetic resin it may be heat softened to make it flexible for the operation of securing the loops thereto. Preferably, sewing is effected on a sewing machine using a device comprising a lever, disposed at a height of 10 - 15 mm. above the backing, over which the filament is alternately drawn to the left and to the right to form the loops. On the underside of the backing the filament may be secured by a backing thread, Fig. 1a (not shown). The stitches in adjacent rows may be offset in relation to one another.  To manufacture a roller hair curler after formation of the loops, a thermoplastic backing is rolled before cooling into tubular form and the contacting longitudinal edges are sewn or welded together.  The curved heads of the loops are cut off by a shearing machine to conform to an envelope of diabolo shape, Fig. 2 (not shown).  The invention is also applicable to forming nail brushes, Figs. 3a and 3b (not shown), toothbrushes and door mats.

IPC: F16K1/12
Filed: 1963-02-06
Abstract: 1,038,161. Valves. NAKSKOV SKIBSVAERFT A.B. Feb. 6, 1963, No. 4910/63. Heading F2V. A valve member intended for shipboard operation in fuel or ballast pumping or bilge suction is operatively connected with a reciprocable hollow cylinder to the interior of which pressure fluid is supplied to open the valve against the pressure of a valve closing spring. A substantially pressure balanced closure member 16, having frusto-conical faces 17 upon frusto-conical seats 19, obturates the passage between inlet 12 and outlet 14 under the closing force of a spring 22 acting from flange 32 upon cylinder 18 to which is fixed valve stem 20. The valve is opened by pressure fluid admitted via inlets 24 and 28 to the interior of cylinder 18 which is thereby forced to slide upon cylinder 26 against the action of the spring 22. In a further embodiment (Fig. 2, not shown) obturation between ports 44 and 46 is effected by cylindrical member 50 joined by webs 70, 72 &c. to stem 20 connected to a cylinder 18 operating against spring 22 contained within an interior housing 48 joined to exterior housing 42 by webs. Valve member 50 seats against synthetic rubber sealing ring 66 carried upon the lower seat and carries a similar sealing ring 84 to seal against the annular seating ring 68 retained by set screw 80 in sealing engagement against synthetic rubber sealing ring 82 within the tubular portion 64 of port 44. A valve setting mark 94 upon member 50 is visible through an aperture 90 normally closed by member 92. The valve may be tested in the closed position by supplying pressure fluid through a similar aperture 96 and observing for leaks through aperture 90. The interior of the housing 48 may be supplied with fluid via passage 88 to protect the spring 22 against corrosion. Impurities and slurry within the cylinder 78 are drawn off through fluid inlet 52 via the pipe 86. A packing 76 is provided around the cylinder 18 with a scraper ring 78 to prevent impurities entering the housing 48. In a further embodiment (Fig. 5, not shown) spaced apart coaxial inlet and outlets are each simultaneously obturated in a manner similar to the Fig. 2 embodiment by members carried upon cylinders operated in opposite directions on the same axis.

Title: Improvements in the treatment of olefinic hydrocarbons for the production of alcohols, ketones and other substances
IPC: C07C29/04
Filed: 1941-04-17
Abstract: Olefinic hydrocarbons containing 7 to 11 carbon atoms or mixtures such as coal oil obtained in the low temperature carbonization of coal or Edeleanu extract from petroleum oils are treated to obtain alcohols and ketones having the same number of carbon atoms.  The oil is hydrated by treatment with sulphuric acid, of 85-95 per cent strength and in amount twice that required for conversion of the olefines into alkyl hydrogen sulphates.  The hydration is effected at between 0 DEG  C. and room temperature and in presence of copper and silver salts and particularly cuprous chloride in presence of copper turnings.  A mixture of secondary and tertiary alcohols is obtained by steam distillation of the diluted mixture, and ketones are formed therefrom either by oxidation for example by chromic acid or by catalytic dehydrogenation as by passing the vapours at 250-400 DEG C. over a catalyst such as copper deposited on pumice, asbestos or bentonite.  The tertiary alcohols form again the corresponding olefines which are separated from the ketones by solution in sulphuric acid or by distribution between two non-miscible solvents such as light petroleum and methanol, the latter of which dissolves the ketones.  In an alternative process the olefines which form tertiary alcohols are first separated by preliminary treatment with a weaker acid, e.g. sulphuric acid of 60 per cent strength followed by hydrolysis of the product and separation of tertiary alcohols. Specification 574,963 is referred to.

Abstract: 826,106. Cutting by fusion. UNION CARBIDE CORPORATION. Feb. 19, 1958 [Feb. 20, 1957; June 17, 1957], No. 5351/58. Class 83 (4). [Also in Group XI] In the constricted-arc cutting of metals using an inert gas shielded non-consumable electrode E, Fig. 6, and a nozzle 138 with a constricted orifice 140, a stream of gas which is chemically active to the workpiece is introduced into the outer portions of the inert gas stream prior to its discharge through the orifice 140. The electrode E of thoriated tungsten is held in a collet H and is surrounded by a shielding gas tube 126 of refractory material into which the shielding gas, which may be nitrogen, argon, helium, hydrogen or mixtures thereof, is admitted from a pipe 110. Inlet and outlet conduits 112, 117 for cooling water lead to a water jacket J; the current supply lead 115 passes within conduit 117. A chemically active gas such as oxygen, air, carbon dioxide or water vapour is admitted through conduit 136 outside the tube 126 and into nozzle 138 which has a water jacket 144. For starting the cutting arc by ionizing the gas, a pilot arc is established by a high-frequency current supply between the electrode and nozzle. This current supply is stopped after the cutting arc has been established using direct current between the electrode and workpiece. An electric control circuit including solenoidactuated valves for the gases and water is described, Fig. 7 (not shown) and this enables the cutting action to be stopped if the torch runs off the edge of the workpiece or is raised or the water supply is interrupted or decreased. In other embodiments the shielding gas tube 126 is omitted and the active gas is admitted through ports in the constructed orifice, Fig. 1 (not shown) or in the nozzle between the orifice and electrode, Fig. 2 (not shown). The active gas may be water vapour admitted through a porous metal or ceramic lining to the orifice, Fig. 5 (not shown) or in another embodiment, Fig. 4, it may be atmospheric air admitted through lateral passages 40 between a main copper nozzle portion 12 and an annular portion 30 insulated from each other and supplied independently with current through resistors 36, 38 from a source S. The workpiece 16 need not be connected in the current circuit. Specific examples are given for cutting mild steel and aluminium and references are included to the cutting of magnesium, carbon steel, stainless steel, nickel and copper.
