Filed: 1928-07-19
Abstract: 316,428. Gordon, K., and Imperial Chemical Industries, Ltd. July 19, 1928. Right to Patent relinquished. Ammonium phosphate; ammonium sulphate; calcium sulphate.-Phosphatic rocks are treated in a finely-divided form with ammonium sulphate and sulphuric acid on the counter-current principle. The process is carried out in a series of vessels, fresh acid entering a vessel containing nearly exhausted phosphatic material, while fresh phosphate enters a vessel at the opposite end of the series containing spent acid, with ammonium sulphate and ammonium phosphate in solution, thus the phosphatic material progressively encounters stronger acid. The reaction may be conducted at any temperature up to the boiling point of the solution, the reactants preferably being agitated. The contents of each vessel are separated by means of a thickener or settling vessel, or a rotary filter, before passing on to the next respective reaction vessels. When carried out at a temperature above 80‹ C., and approaching the boiling point of the solution, the precipitate of calcium sulphate hemi-hydrate is converted into large crystals of gypsum by cooling, before filtration. When working at ordinary temperatures the separated gypsum is treated at a raised temperature and preferably in acid solution to form the hemi-hydrate, which, on cooling, is converted into relatively large crystals of gypsum. The wash water may consist of ammonium sulphate solution. The gypsum obtained in the process may be suspended in water, and treated with ammonia and carbondioxide, the solution of ammonium sulphate produced being used as raw material in the process described above.

Abstract: 1,216,788. Digital data store. SIEMENS. A.G. 25 April, 1969 [26 April, 1968], No. 21210/69. Heading G4C. [Also in Division H4] In a data processing system in which data items can be classified into groups having different degrees: of. priority, data items requiring intermediate storage are each entered into arbitrary storage locations and supplemented by data giving its group priority and order of arrival relative to other members of that group. It is stated that the processing system may be a central control in a telephone. exchange. In the arrangement shown data items from a source Q are entered into intermediate store SI for read-out on demand by a. utilization device E. The intermediate store is an associative store having an address portion SA into which the supplemental data comprising the addresses is entered as the items of data arrive. A device PD (not detailed) determines the priority group to which each item. of data belongs and increments a corresponding input counter such as PG1 : EN1 the output of which is characteristic of the order of arrival of that -item relative to others in its group. Both the group and. order.. within a group designations are entered as an address in SA. In addition to having an. input counter each priority group has an output counter such as. AN1 incremented each time an item of data is read-out. In each group the counters register equal counts only when no item of data having that group priority is stored in the intermediate store. Any difference between the counts is detected by a comparator such as V1. When the data is required by the utilization device E a. device. AS responds testing the group equipments in turn until a group (that of the highest. priority) is found for which data items are stored, this being indicated by the output of the comparator. The addresses of the items (given by the settings of the counters of that group) are entered into a read-out register AR. The addresses in SA are sequentially compared with each address in AR and when a match occurs the corresponding item of data is read out to the utilization device. The item of data is given a number which is transmitted to the utilization and together with the item of data stored for a predetermined time. If the utilization device fails to receive an item or if a parity check indicates an error it returns the number requesting repeat transmission. In a modification in which the intermediate store is stated to be a rotary store a plurality of read-out registers are provided.

Patent GB-756743-A (GB)
Title: Improvements in or relating to isocyanate-modified polyester rubbers
Inventor: BIRLEY ARTHUR WILLIAM
Filed: 1953-07-31
Abstract: Diisocyanate-modified polyester rubbers are cured by heating in the presence of catalytic quantities, e.g. 0.01 per cent to 0.1 per cent by weight of the polymer, of beryllium hydroxide.  The polyesters are derived from one or more aliphatic glycols and one or more aliphatic glycols and reacted with a diisocyanate, preferably an aromatic diisocyanate, in molar excess, the excess depending on the molecular weight of the polyester.  Isocyanates containing more than two isocyanate groups may be used provided that they behave bifunctionally.  The modified polyesters preferably have a molecular weight greater than 5000 and preferably of 7,500-12,500.  The cured products have better resistance to hydrolysis by steam than those cured in the presence of alkali or alkaline earth hydroxides.  Other bifunctional reactants may be present in the curing reaction, water, glycols and diamines being referred to.  In an example, 200 parts of polyethylene adipate of molecular weight 1970 were reacted at 140-150 DEG  C. for 20 minutes with 26.7 parts of naphthylene 1.5 diisocyanate.  0.109 parts beryllium hydroxide were then mixed in and the reaction continued for 20 minutes to give a tough rubbery mass which was pressed at 150 DEG  C. and 700 p.s.i. for 15 minutes and after-cured for 16 hours at 80 DEG  C.  A comparative specimen cured in the presence of calcium hydroxide had inferior resistance to hydrolysis by exposure to steam at 100 DEG  C. for 10 hours.  Other diisocyanates referred to are 1-methylphenylene-2.4, 2-nitrodiphenyl - 4.41, 2 - nitrodiphenylmethane - 4.41, naphthylene - 1.4, naphthalene - 2.7, fluorene, chrysene, 1 - chlorophenylene - 2.4, tolylene, diparaxylylmethane - 4.41, 4.41 - diphenylene and 4.41-cyclohexylphenylene diisocyanates.

Apparatus for automatically connecting rubber soles, e.g. solid, foam or crepe rubber soles, to leather or textile uppers by pressure and heat comprises a number of press stands 1 each having a rotatable cross-member 65 carrying a last 66, a pair of vertically displaceable and horizontally slidable side pressure members 22, 23 having exchangeable sole press plates 34, 35, a press platen 8 upwardly displaceable to a working position, cross-bearers 26, 27 fastened to side walls 2, 3 of the stand to limit the upward displacement of the press platen 8, a press plate 13 supported on the press platen 8 and movable independently thereof by the inflation of an air cushion 11, a sole supporting plunger 37 with attached heating plate 36 vertically displaceable between the side pressure members 22, 23, two pairs of levers 18, 19 arranged to slide the side pressure members towards each other on the press platen 8 being raised, and downward projections 9, 10 on the bottom of the press platen 8 arranged to be engaged by cams 57, 58 on the raising of the platen to retain the movable parts in their operative positions. The levers 18, 19 are pivoted at one end on lugs 14, 15 carried by the press platen 8 while at the other end pins 20, 21 pivotally connect them to the side pressure members 22, 23. The pins 20, 21 are guided by L-shaped slots 30, 31 in plates 24, 25 attached by screws 59 to the underside of the crossbearers 26, 27 so that when the press platen 8 is raised, the side pressure members 22, 23 first move vertically and then horizontally toward each ether. Displacement of the press platen 8 is effected by means of a piston rod 51 slidable under fluid pressure in a cylinder 52 and connected to the platen by a bracket 47. A toothed rack 53 is carried by the bracket 47 and engages a toothed pinion 54 on a crossshaft 56 carrying the cams 57, 58, Fig. 6, provided with small facets 71 to co-operate with the projections 9, 10. An additional safeguard for maintaining the press platen 8 in its working position is provided by spring-loaded pawls 55, Fig. 5, two on each side of the platen, carried on pins 68 and held by spring-loaded plungers against teeth 69 on the platen which is thereby flexibly held so long as the cams 57, 58 are in their raised position. The last 66 is swung between upward and downward pointing positions by means of a pneumatic cylinder (not shown), the action of which is transmitted by a chain and sprocket wheel, for example, to the cross-member 65. A further upward movement of the press plate 13 is effected by inflation of the air cushion 11 by compressed air through a valve 12. The movable parts of the apparatus are automatically controlled by means of a timer switch (not described).
