Patent GB-861052-A (GB)
Title: Moulded synthetic detergent compositions
IPC: C11D1/14
Filed: 1958-11-24
Abstract: The invention comprises in moulded form, ammonium salts of n-alkyl sulphonic acids containing an average of 12-16 carbon atoms in the alkyl group or a mixture of the ammonium and sodium, potassium, calcium, barium, magnesium, aluminium or other metal salt of n-alkyl sulphonic acids containing 8-20 carbon atoms (see also Group III). Suitably, the sulphonates are prepared by reacting appropriate olefinic materials with ammonium bisulphite in aqueous alcohol, de-oiling by solvent extraction or dilution with water to remove unchanged hydrocarbons and when the mixed salts are required, adding an appropriate metal base to displace some of the combined ammonia; the alcohol is then distilled off and water thereafter removed to leave a slurry which is solidified on cooling and is suitable for moulding.  Examples relate to the ammonium salts of n-dodecyl, tetradecyl, hexadecyl and C4-15 and C12-16 n-alkyl sulphonates and various calcium, sodium or magnesium ammonium mixed salts of n-alkyl sulphonic acids containing 8-20 carbon atoms.ALSO:A moulded synthetic detergent composition consists of a moulded mass of at least one ammonium alkyl-sulphonate, the alkyl radical being a straight-chain radical of 12-16 carbon atoms, preferably dodecyl, tetradecyl or hexadecyl.  Where a mixture of two or more sulphonates are used, the alkyl groups present should differ by not more than 3 carbon atoms. If required, n-alkylsulphonates of alkali metals such as sodium, and potassium, of alkaline-earth metals such as magnesium, calcium or barium, or of aluminium may be included, the alkyl groups here containing 8-20 carbon atoms, and the ratio of metal sulphonate to ammonium sulphonate being 10-15 mol. per cent to 75 mol. per cent or more.  The bars are obtained directly following the preparation of the ammonium alkyl sulphonate (see Group IV (b)) by displacing the ammonium radical by the appropriate metal base to the desired extent (if at all) and then heating the sulphonate until the water content is 20-25% by weight whereupon the thick slurry at 100 DEG  C. is dropped on to a chilled roll, where it solidifies, is then chipped off, and finally air-dried to a water content of 1-10% by weight. Ammonium sulphate is generally present in the bars, which may also contain 5-65% by weight of fillers, perfume, and dye.

Abstract: 1,196,275. Multifilamentary yarns of composite filaments. CHEMIEFASERWERK SCHWARZA WILHELM PIECK. 18 Aug., 1967, No. 38070/67. Heading B5B. Multifilamentary yarns the individual filaments of which are of the composite type having crimp potential and which are bulky or voluminous when heated to cause the individual filaments to crimp are produced by spinning different synthetic high polymer components having different shrinkage properties through spinnerets having separate supply chambers for the individual components, said components being united without substantial mixing, either immediately in front of the spinneret face, or within the spinneret orifices or within the inlet ducts of the orifices, whereby there is obtained a multifilamentary yarn, the individual filaments of which are composite and have a circular or a profiled cross-section, the individual filaments differing from one another in the shapes of their cross-sections and/or in the ratios of the areas of their cross-sections corresponding to their components and/or the distribution of these areas, these characteristics remaining constant over the total length of each individual filament. The filaments are preferably bicomponent filaments and the polymers used may be polyamides or polyesters. In an example, a 30 denier yarn consisting of six individual bicomponent conjugated filaments of circular cross-section is produced by simultaneously extruding through each of the six orifices of a spinneret adapted for the spinning of conjugate filaments a molten polycaproamide and a copolymer consisting of 80% polycaproamide and 20% of polyhexamethylene adipamide. The multifilamentary yarns thereby produced are stretched at a stretch ratio of 3À35: 1 and shrunk in water at 100‹ C. for 10 minutes, producing a crimp contraction of 40%.

Title: Sequence camera
IPC: G03B19/06
Filed: 1963-09-27
Abstract: 999,748. Sequence cameras. PHOTOGRAMMETRY Inc. Sept. 27, 1963 [Nov. 14,1962], No. 38146/63. Headings G2A and G2E. A multi-lens sequence camera has eight lenses 15 each focused on a separate part of a single frame of film F, and each having an independently movable single blade shutter 45a-45h actuated by springs 47a-47h,the shutters being released sequentially upon successive increments of movements of a release slide 95. A mask 59 comprises eight tapered compartments in two banks of four and is made at moulded plastics material, the transverse end walls 63 each having an aperture 64 aligned with openings 42 in channel section metal members 30, 31 containing the shutters 45, and with openings 65 in retainer plates 66, 67 for two aperture selecting bars 68, 69 which have eight sets of three apertures 71, 72, 73. Aperture selection control 22 rotates lever 75 whose ends are pivoted to bars 68, 69. The side walls 34, 37 at channel members 30, 31 have a series of slots 90 which receive the longer legs 49a-49h of shutter springs 47, and when the camera is cocked, legs 49 rest against cam edges 93 of these slots. The shutters are sequentially fixed as the spring- biased slide 95 is released and moves to the right, when the wedges 96a-96h operate one after another to push springs 49 over edges 93. The intervals between the eight exposures are controlled by varying the speed of slide 95, the shutter speeds being independent of this variation. The speed of slide 95 under the action of spring 97 is determined by the rate at which needle valve 117 allows air into the glass cylinder 110 thereby controlling the speed of a piston 114. A pinion 122 carried by arms 124 on slide 95 meshes with a fixed rack 125 and a movable rack 127 attached by a lost motion connecting rod 128 to piston 114. Knob 25 sets the needle valve 117 by which exposure intervals at from 1/4 to 1/16 second are provided. Shutters speeds of 1/2000 second are achieved by the use of a small aperture 55 in the shutter blades 45. Spring- loaded sliding member 130 holds the camera in the cocked position by means of an inturned end 132 which holds leg 49 of spring 47a against the action of wedge 96a. When member 130 is moved to the left by trigger 24, the springs 49 may then be released in sequence by slide 95. The travel of slide 95 is limited by engagement of its end 138 with end 139 of a cocking slide 140 whose pushing elements 141 engage legs 49. The camera is cocked when slide 140 is moved to the left against spring 146 by handle 23. During this movement the air in cylinder 110 is expelled by piston 114 through the flap valve 120. The camera may use "Polaroid" (Registered Trade Mark) to be processed within the camera body.

A footvalve for liquid lift pumps has a valve member 4 with a closure face 4<1> displaceable under the influence of a pressure differential thereacross to connect or disconnect the intake 8 of a suction conduit 5 to or from an ambient source of liquid supply, e.g. via port 12 and filter 13 in perforated casing 14, and means, e.g. float 9, responsive fall in liquid level of the source to close the valve when the liquid level falls to a predetermined height by the creation of the pressure differential and vice versa. With the float at its normal raised position (shown), suction in the conduit 5 acts via a port 25, controlled by valve member 30, and a port 34 in a closed chamber formed by walls 1b, conduit 5 and diaphragm 4, and the diaphragm is maintained raised by the pressure differential to connect the intake 8 of the conduit to the liquid supply. Should the liquid level fall the float will close the valve 30 through the action of a sleeve 21 sliding rightward in a housing 22 and the force of an interposed spring 33 acting on the valve member 30; and a further fall of the float will cause the sleeve 21 to compress the spring 33 to open a valve formed by a valve head 31 attached to the stem 29 of the valve 30 and a port having a rubber bush 27, a clearance bore 28 in the sleeve then provides a communication between the space above the valve member 4 and the outside ambient conditions, e.g. the atmosphere, so that the diaphragm closes on its seat owing to ambient pressure acting on the upperside of the diaphragm and the suction at 8 on the underside.
