Title: Treatment of Woolled Animal Skins and the Production of Pile and Other Fabrics Thereby
IPC: D04H11/00
Filed: 1966-08-22
Abstract: 1,160,723. Coated porous textiles. L.W.S. NOMINEE CO. Ltd 22 Aug., 1966 [1 Sept., 1965], No. 37449/66. Heading B2E. [Also in Divisions C6 and D1] An imitation leather material is made from a porous textile substrate such as a non-woven wool felt, or a woven and felted wool fabric, to which an elastomeric polymer or plastic surface layer, such as polyether or polyester urethane or polyvinyl chloride, is applied in a liquid state. The free ends of the hairs of animal skins are straighteend by electrostatic or other means and embedded in the polymeric layer. The polymeric layer is then partially dried and/or cured and the animal hairs pulled out leaving a surface with tiny holes or follicles after which drying and/or curing is completed. Alternatively, the drying and/or curing can be completed with the animal hairs still embedded in the polymeric layer and the hairs then cut off flush with or just above the surface, leaving the hair ends embedded in the polymeric layer. In both forms the material is finally dressed as by buffing to produce a smooth leather-like surface.

Title: Analyzer for the sequencer controller of an automatically controllable machine
IPC: G05B15/02
Filed: 1972-08-11
Abstract: 1399356 Automatic control DIGITAL EQUIPMENT CORP 11 Aug 1972 [13 Aug 1971] 37621/72 Heading G3N A control system as disclosed in Specification 1290651 is modified by the addition of an analyzer and a data processor whereby the status of the system can be diagnosed. The analyzer stores the preceding state of each sensor or controllable device of a machine in an addressed location in a store. As the controller of the control system executes, in sequence, each instruction in a governing function, the analyzer uses the address instruction to retrieve the corresponding stored state and compare it with the response obtained by the controller. A determined difference causes the analyzer to generate a word, specifying the transition in status which is fed to a data processing system and listed. Malfunctions can then be diagnosed by comparing the prepared list with a reference list.

Title: Improvements in and relating to coin holders for prepayment mechanisms for gas and electricity meters and for like purposes
IPC: G07F15/02
Filed: 1946-12-23
Abstract: 620,528. Prepayment mechanism for meters and other apparatus. SMITH METERS, Ltd., CHARLES, A., and CHARLES, J. A. Dec. 23, 1946, No. 37686. [Class 27] Coin-discharging mechanism.-Prepayment mechanism, such as is employed in meters and comprising a rotatable coin holder for engaging and turning a measuring-out wheel as the holder is turned from a coin receiving position to a discharge position, is provided with a pivoted closure plate for the discharge opening of the holder; the plate engages a fixed stop at the discharge position so that it is pivoted against a closing spring to release the coin, and the pivotal axis of the plate is parallel to the plane of a coin in the'holder and in a plane at right-angles to the axis of rotation of the holder. The coin holder 6 is carried on the usual slot plate 7 rotatably mounted behind a front pricechange plate 1, and spaced lugs 16, 17 project from one side 'wall to carry the spindle 18 of the closure plate. The closure plate proper 19 is sector-shaped and normally overlies the outer discharge end of the holder 6; it is formed with a strengthening flange 22 and an extension 23, and is mounted on the spindle 18 by means of a hole 20 in the plate 19 itself and a hole 26 in the inturned end 24 of the extension 23. A torsion spring 27 normally maintains the plate 19 over the coin holder but, as the holder approaches its discharger position, a lug 29 on the plate engages a fixed stop 28 so that the plate is swung clear and the coin discharged by the time the holder reaches its terminal point determined by a stop 12. A modification is referred to in which the closure plate is pivoted on the slot plate 7 instead of on the coin holder itself. Price-changing mechanism.-The initial position of the coin holder and hence the extent of prepayment for each coin is adjustable by turning the price-change plate 1 in its seating 2 after releasing a locked guard ring 5. The plate 1 carries a rearwardly projecting pin against which a finger 10 on the slot plate 7 abuts in the initial coin-receiving position.

Abstract: 797,793. Making plates, sheets, bars, etc.; working at specified temperatures; rolling; forging. HRUBY, A. Dec. 21, 1956 [Dec. 23, 1955], No. 38931/56. Classes 83 (2) and 83 (4). A method of protecting ingots, blooms, billets and other ferrous metal forms, e.g. plates and bars against scaling, during heating and shaping in a warm condition comprises cleaning the surface of the form and coating it with aluminium by submersion for several minutes at 850‹ C., then heating the form preferably for from two to three hours and to from 1100‹ C. to 1300‹ C., to produce a plastic and oxidationresisting layer of a solid solution of the basic metal and 10 to 15 per cent of aluminium and shaping in the warm condition, e.g. by rolling or forging. The cleaning prior to coating with a layer of aluminium, e.g. 0.15 mm. thick may be by sand or shot blasting or by pickling, any flaws being removed by grinding or chiseling. In a modification, heating the form after coating at a temperature of from 800‹ C. to 900‹ C. for preferably ¢ to 1 hour causes less diffusion of the coating and the formation of a hard and brittle layer of A1-Fe phases containing 15 per cent or more aluminium, which are not plastic even in the warm condition. After rolling, a thin surface layer of comminuted Al-Fe phases is left which may be removed by pickling or may be retained to increase resistance to scaling and corrosion.

Title: Carbonylation synthesis reaction
IPC: C07C45/50
Filed: 1956-12-27
Abstract: Oxygenated compounds are prepared by reacting an olefin with carbon monoxide and hydrogen at 60-240 DEG  C. and 1000-10,000 p.s.i.g. in the presence of a rhodium-containing catalyst capable of being dissolved in the reaction mixture under the reaction conditions.  The rhodium catalyst may be combined with a cobalt catalyst.  The olefins may be pure or as hydrocarbon mixtures containing olefins.  Specified olefins are non-conjugated diolefins such as dicyclopentadiene and its alkyl derivatives, terpenes and vinylcyclohexene; mono-olefins, cyclic olefins such as cyclohexene; styrene and olefin polymers.  In general, C2-20 monomeric olefins and their polymers may be used. The H2:CO ratio is generally 0.5:1 to 10:1, low ratios (0.5-1.5) being preferred for aldehyde production and higher ratios (2-4) for alcohol production.  Forms in which the rhodium may be added include metallic rhodium, a rhodium oxide, a salt such as a halide, nitrate, sulfate, sulphite, oleate or stearate or a rhodium carbonyl.  A preformed soluble catalyst may be used dissolved in an organic solvent.  The catalyst may be deposited on a carrier, generally 1-40 per cent by weight based on rhodium of rhodium compound to the carrier.  The catalyst concentration may be from about 0.002 to 20 mol. per cent based on the rhodium to the olefin.  The rhodium may be recovered from the product by treatment with water at elevated temperature, e.g. 5-40 per cent by volume water at 80-200 DEG  C.  In examples: (1) butene-1 is carbonylated to mainly aldehyde products with some acetals and alcohol, reduced rhodium metal/alumina, rhodium sesquioxide and rhodium chloride being mentioned as catalysts; (2) a soluble catalyst is preformed in hexane solution from rhodium sesquioxide and CO/H2 mixture and used for the carbonylation of butene-1; (3) butene-1 is carbonylated using rhodium sesquioxide and the rhodium is recovered from the product by heating with water at 180 DEG  C., filtering and drying, and reused; (4) butene-1 is carbonylated using rhodium sesquioxide and the product hydrogenated to amyl alcohols using a nickel catalyst; (5) dicyclopentadiene and alkyl derivatives thereof are carbonylated to the mono-unsaturated aldehyde together with some of the corresponding alcohol using rhodium sesquioxide in hexane solution; the aldehyde may be converted to the acetal and this oxonated further to the aldehyde derivative, which may be hydrolysed to the dialdehyde and subsequently reduced to a glycol; the mono-unsaturated aldehyde may also be reduced to the unsaturated alcohol with metal hydrides and this oxonated further to form, after reduction, a glycol of dicyclopentadiene.
