Title: Unsaturated fatty acids and salts thereof and a process for their preparation
IPC: C07C57/18
Filed: 1959-12-10
Abstract: The invention comprises compounds of the general formula: CH3(CH2)x-CH2-C­C-(CH2)7-COOR (wherein x is 1, 3, 5 or 7 and R represents hydrogen or one equivalent of another physiologically harmless cation, e.g. a physiologically harmless metal such as an alkali metal, calcium, magnesium or aluminium, ammonium or the cation of an organic base, e.g. an ethanolamine, ethylene-diamine, procaine, piperidine, pyrrolidine, morpholine, streptomycin, dihydrostreptomycin or isonicotinic acid hydrazide), and the preparation thereof by (a) condensing a compound of the general formula: CH3-(CH2)x1-C­C-R1 (wherein x1 is 2, 4, 6 or 8 and R1 represents a metal or a Grignard reagent residue) with a compound of the general formula: Hal-(CH2)7-R2 (wherein Hal represents a halogen atom and R2 represents -COOR or a radical convertible thereto), or (b) reacting a compound of the general formula: R1-C­-C(CH2)7-R2 with a compound of the general formula: Hal-CH2-(CH2)x-CH3, or (c) eliminating a substituent capable of elimination from the heptamethylene chain of a compound of the general formula: CH3(CH2)x-CH2-C­C-(CH2) 7-R2 (if necessary after protection of the triple bond), and in all cases, if necessary, converting R2 to -COOR, and, if desired, converting a resulting acid into a salt with a physiologically harmless base or a resulting salt into the free acid. Pharmaceutical preparations.-The foregoing compounds have inflammation- and edemainhibiting activity, for which purpose they may be injected, e.g. intravenously or intraninsularly, in the form of physiological isotonic solutions of the appropriate salts, or suspensions of sparingly soluble salts or of the free acids. 1-Chlorohexadecyne-(8) is prepared by reacting nonyne- (1) with 1-chloro-7-iodoheptane in the presence of sodamide or lithium amide, or by reacting 9-chlorononyne-(1) with heptyl iodide in the presence of lithium amide.  Analogous compounds are obtained by replacing nonyne-(1) by pentyne-(1), heptyne-(1) or undecyne-(1) in the first process.  9-Chlorononyne-(1) is prepared by reacting 1-chloro-7-iodoheptane with sodium acetylide.  Organometallic compounds of the second general formula above are prepared by reacting pentyne-(1), heptyne-(1), nonyne-(1) or undecyne-(1), or their mercury compounds, in a boiling inert solvent, with the salt-forming metal or metal compound added in finely divided form, e.g. finely divided lithium, magnesium, lithium amide, sodium oxide, ethyl magnesium bromide or phenyl lithium.

Microporous plates or foils such as for use as filter membranes in electrolytic cells or separators in galvanic elements, e.g. lead-acid accumulators are produced from a mixture consisting of pulverulent thermoplastic material, e.g. polystyrene, polyethylene or polyvinyl chloride with pulverulent pore-producing material, i.e. pulverulent material having porous grains so as to impart porosity to the plate when incorporated therein, e.g. cork flour, lignin, diatomaceous earth, sawdust, coke flour, asbestos or similar porous acid-resistant electrically insulating material, a uniform layer thereof being sintered, and then caused to pass one or more rolls and then one additional sintering zone. The microporous material may be compressed by rolling so as to form grooves or ridges on one or both sides thereof. The mixture is preferably 20-80% thermoplastic, the remainder being the pore-producing material.

Abstract: 1,086,800. Semi-conductor lasers. STANDARD TELEPHONES & CABLES Ltd. Sept. 23, 1966, No. 42499/66. Headings H1C and H1K. The PN junction 5 of a semi-conductor injection laser emerges at the light emitting surface 1 of the crystal in a plane displaced from the light emitting plane. The opposite surface 2 may be provided with a dielectric layer 3 and a metallic layer 4. If reflective layers are not provided the junction also emerges at surface 2 in a plane displaced from the light emitting plane, and may do so when reflectors are provided. The crystal may be of gallium arsenide and is formed from a slice of N-type material by laying masking strips of SiO 2  on one major surface parallel to the (110) plane, diffusing P-type material into the masked surface, and cleaving parallel to the (110) plane either through or between the masked regions, depending on whether the required surface 1, 2 is to have the PN junction in the light emitting plane or displaced from it. The device may be mounted between massive electrodes acting as heat sinks.

Title: Improvements in or relating to shoe making
Inventor: TUTT KINGSLEY JOHN
IPC: A43D25/06
Filed: 1964-10-20
Abstract: 1,122,132. Boots &c. BRITISH UNITED SHOE MACHINERY CO. Ltd. 19 Oct., 1965 [20 Oct., 1964], No. 42645/64. Heading A3B. A machine for stretching the vamp of a shoe upper in preparation for lasting has a clamp 34 which clamps the vamp against a bed plate 2 leaving unclamped two triangular portions of the vamp arranged apex to apex across the instep and two deforming members 10, 12 which deform the unclamped portions into two bulges which increase in size from the centre to the edge and which are actuated in response to the clamping of the upper. The clamping members 40, 42, 44 are carried on an arm 30 which is pivoted to the machine frame at 32 and which can be moved into clamping position by the operator by means of a handle 38. When the arm 30 is moved into its clamping position a member 54 moves under a catch-plate 52 on the arm 30 to actuate a valve 80 which supplies compressed air to cylinder 72 and applies clamping pressure to the arm 30 via piston rod 70, arm 64, pivot 58 and the member 54. A cam on the piston rod 70 actuates a valve which supplies compressed air to cylinders 116, 116<SP>1</SP> and 164 which raise the two instep deforming members 10, 12 and a throat deforming member 18 respectively. The instep deforming members 10, 12 are semi-conical in shape and pivot about an axis lying in the plane of the shoe upper. The members 10, 12, 18 may be heated. After a pre-determined time interval the deforming members 10, 12, 18 are lowered, the clamping pressure is released and a piston 76 in the arm 30 moves under the member 54 from under the catch plate 52 so that the arm 30 is raised by a spring 48.

Title: Device for preventing violent closing and opening of a door or the like
IPC: E05F15/02
Filed: 1964-10-21
Abstract: 1,072,518. Door operating appliances. HAGGLUND & SONER A. B. Oct. 21, 1964 [Oct. 25, 1963], No. 42835/64. Heading E2M. A door or hatch 10 is operated by a hydraulic cylinder 12 connected to a safety valve 28, which, if an obstacle is pressed against a sensitive strip 16 when the door is being closed, diverts working liquid, which after leaving the cylinder 12 via conduit 38 would usually pass through conduits 40 and 66 to a reservoir 68, so that it passes instead through conduit 36 to a chamber 48' thereby raising an operating valve from the closing position (in which piston 44 is aligned with the conduits 40, 62, 64, 66) to the opening position (in which piston 46 is so aligned). The door or hatch 10 is thus stopped and may be arranged to reverse a little as working liquid is now delivered by a pump P through conduits 62 and 40 to push the safety valve into the position shown and may then push the piston 12' to the right. The liquid in chamber 48' may drain via a throttle valve 74 to the reservoir 68 while the operating lever 56 returns to a neutral position (as shown) under the bias of springs 58, 60. The invention may be applied to hinged doors or hatches, Fig. .2 (not shown).
