IPC: D01B9/00
Filed: 1926-01-19
Abstract: 260,935. Oberrheinische Handelsges. Nov. 6, 1925, [Convention date]. Fibres, roughening mechanically; fibres, treating.-The spinning qualities of normally smooth fibres such as artificial silk and the like are increased and finer, softer, stronger, and more fluffy threads obtained without the use of excessive twist by treating the fibres with substantially granular, crystalline or amorphous roughening agents before carding and spinning. As suitable substances may be mentioned oxides or salts of metals of the alkaline earths, or other metals, or powdered, amorphous and earthy substances of various kinds, of inorganic or organic nature. such as tale, cement or the like, calcium sulphate or caustic lime. Solutions of crystallizable substances may be used to obtain a coating of fine crystals and the solutions thereof may be sprayed on or applied by immersion of the fibres therein. The substances used may be mixed with water and applied in suspension or they may be precipitated from a solution, as for example in mordanting, on to the fibres, or caused to adhere thereto by the use of a lubricating or fattening agent or agglutinant or adhesive such as soap, oleine dextrine or the like. The fibres may be treated with a suspension of organic colloids such as starch solutions, gelatine or the like and slowly dried. Waterproofing processes such as treatment with sulphate of alumina followed by animal or other glue, soap and the like may be used. Previously curled fibres may be treated and the roughening treatments above mentioned may be combined with stirring, centrifuging, pounding, pressing, fulling and a subsequent curling treatment in suitable wet or dry condition. The curling tendency is thus increased and the spinning qualities further improved.

Abstract: 100,192. Gibbons, F., and Ell, A. G. Feb. 4, 1916. Mechanical shooting galleries.-Balls are shot from a pistol a at a target b comprising a number of movable figures c; balls which pass through the target are conveyed by a shoot p to a channel o' in a slide o, which is free to be raised to return the balls to the pistol by the operation of a drawbar d; balls which fall in front of the target are conveyed by a shoot to a channel i<1> in a second slide i, which can only be raised to return the balls to the pistol after the insertion of a coin. The draw-bar d is connected to the slide o through linkage l, m, n, and, when the slide is raised, the balls pass from the channel o', through a shoot k<1>, channel i<2> in slide i, and shoot k to the pistol. The slide i is operated by a rod d<2>, which is adapted to be connected to the draw-bar d by a weighted pawl f when a coin is inserted; a projection d<3> on the rod d<2> operates a bell-crank lever g connected to the slide i by a link h; in the raised position of the slide, the balls pass from the channel i<1>, into a shoot k. A spring-controlled pawl u' co-operating with a rack v ensures a full stroke of the draw-bar. A frame w connected to the rod, d through links w<2>, w<3> serves to return the figures c to the vertical position. The coin inserted in a shoot e depresses the pawl f into engagement with a pin g on the draw-bar d. During the forward movement of the rod d<2>, the coin escapes from the pawl on to a pin q<1> on a spring-controlled lever q, which moves into the shoot c to catch the coin, owing to the forward movement of a projection r on the rod d<2>; simultaneously, an arm s connected to the rod d<2> tilts a lever t, permitting the previously-inserted coin to pass by a shoot t<1> to the money-box. If all the figures c are knocked down, a bar y drops and, through links y<2>, y<3>, rocks a lever z, permitting the coin to pass to a return shoot z<1>.

Title: An improved process of producing oxide of aluminium from chloride of aluminium
IPC: C01F7/22
Filed: 1920-01-19
Abstract: Alumina is prepared from a hydrochloric-acid solution of any aluminous material by calcining the crystals of aluminium chloride obtained by saturating the solution with the gaseous hydrochloric acid resulting from a previous calcination.  The aluminium chloride is calcined in a continuously working furnace, consisting of several storeys each of which is provided with an outlet, and the gases evolved from a particular batch are not conveyed to the aluminium-chloride solution until they contain sufficient hydrochloric acid.  When an ordinary type of furnace is used, the issuing gases are passed through a condenser, in the first chambers of which a watery solution of hydrochloric acid is formed while acid substantially free from water remains uncondensed and is conveyed to the saturator.

Title: Cation exchange resin
Inventor: HATCH MELVIN JAY
IPC: C08F8/00
Filed: 1962-01-17
Abstract: A cation exchange resin contains a cross-linked vinyl aryl polymer to aryl groups of which are attached groups of formula <FORM:0975365/C3/1> where <FORM:0975365/C3/2> is an aliphatic, aromatic or cycloaliphatic hydro-PO3= and M is a cation, e.g. H, a metal, carbon groups, n is 1 or 2,Z is -CO2, -SO3-2 or NH4 and/or substituted NH4, equivalent to the bond sites on Z. The polymer may be a copolymer of styrene and, e.g. 0.2-20%, divinylbenzene. The resins may be made by reacting a cross-linked polymer vinylaryl sulphonium salt with a stoichiometric amount of a water-soluble nucleophillic mercaptide of formula <FORM:0975365/C3/3> where M1 is an alkali metal and the other symbols are as before, e.g. di-sodium thiosalicylate, tri-sodium 1-thio-cyclo-hexane-1, 2-dicarboxylate or trisodium mercaptomethane phosphonate.. The reaction may be carried out at 50-100 DEG C. in the presence of a swelling agent for the polymeric sulphonium salt and an excess of mercaptide. The salt may be formed in situ by reaction of a cross-linked polymeric vinylbenzyl halide, e.g. the reaction product of styrene, vinyltoluene, vinylxylene, chlorostyrene, dichlorostyrene, or vinylnaphthalene, containing 0.25-1.5 halomethyl groups/aromatic nucleus, and a mixture of a sulphide which contains one or two C1- 4 alkyl groups and/or correspondingly one or two C2- 4 hydroxyalkyl groups and the nucleophillic mercaptide.  In an example a chloromethylated styrene-divinylbenzene copolymer was refluxed with dimethylsulphide, methylene dichloride, methanol and water to produce beads of the resin.

Title: Improvements in lid forming and reconditioning machine
IPC: B21D51/38
Filed: 1954-01-21
Abstract: 746,102. Making lids; stamping; angular bending. KRADOSKA, E. C. Jan. 21, 1954, No. 1848/54. Classes 83 (2) and 83 (4). A machine for shaping the lid of a metal drum includes a lower platen adapted to receive the lid to be shaped, either an old indented lid or a blank, an upper platen, a plurality of rimsupporting rolls rotatable about fixed axes located in a plane below said upper platen, means for first effecting axial movement of said platens toward each other into lidclamping position above said rolls and for subsequently moving said platens to a position in which the rim of the lid engages said rolls, a forming roll rotatable about an axis in a plane above the plane of said rim-supporting rolls, and means for driving said forming roll and at least one of said rim-supporting rolls, said driven rolls engaging the opposite sides of the rim of the lid. A used lid 48 to be reconditioned is placed on a lower concave platen 16 with the boss of a bung hole on the lid received in an opening 79 in said platen. The platen 16 is freely rotatable on a piston rod 50 which is raised by a piston in a lower air cylinder 18 to a position in which the rim of the lid is engaged and centred by spaced lugs 94 on a ring 88. An upper convex platen 26 is moved down by piston rod 52, on which it is rotatably mounted, of upper air cylinder 28 first to clamp the lid, remove dents and give it its desired dished form, then both platens move down together to bring the lid rim on to spaced supporting rolls 33, 34, 35, 36. The upper air cylinder 28 has a greater diameter than the lower cylinder 18 but the inlet and exhaust pipes are narrower to effect the above sequence of operations. With the lid rim resting on its supporting rolls, air cylinder means 40 are actuated to cause a driven forming roll 38 journalled in a pivoted housing to move down to engage the top of the lid rim opposite the lower supporting roll 36, both rolls being driven by a motor M switched on, by a switch 96, as the roll 38 descends. The rolls 36, 38 co-operate to rotate the lid, overcoming spring friction on the platens, and flange the rim. The roll 38 is then lifted, the platens moved apart and the formed lid removed. In a modification, Fig. 10, for forming a lid from a flat blank 48<SP>1</SP>, the blank is first centred by pins 102 and the lower platen 16 pushes the blank against a fixed ring 88<SP>1</SP> to bend its periphery down. The blank is then clamped and dished by the downward movement of the top platen 26 and the rim formed as before.
