Patent GB-478237-A (GB)
Title: Improvements in the production of moulding compositions
IPC: C08L1/12
Filed: 1936-06-10
Abstract: A mixture of a cellulose derivative or a synthetic resin and a plasticizer, moistened with a non-solvent for the cellulose derivative or resin, is converted into a powdery or granular form by extruding it in rod-like form through an extrusion machine and, if necessary, disintegrating the extruded material.  The rods need not be of round cross-section, and may break up into granules under their own weight.  This breaking-up may be assisted by cutter blades close to and preferably on the feed side of the extrusion plate.  The extruded material may be obtained in granular form by maintaining the extrusion temperature below 34 DEG  C., while continuous rods are produced at higher temperatures, e.g. 50--70 DEG  C. or more, so that the non-solvent evaporates. Suitable non-solvents are water, alcohols, ethers, benzene and other hydrocarbons, and the proportion thereof may be 50--150 per cent of the weight of the cellulose derivative or resin.  Mixtures produced as described in Specification 476,638 by applying plasticizer uniformly over the surface of moistened particles of plasticizable compound may be used.  The plasticizer may be dissolved in a medium which is a non-solvent for the plasticizable composition.  A number of cellulose derivatives, synthetic resins and plasticizers are specified.

Patent GB-1519465-A (GB)
Title: Analytical tape
IPC: G01N33/487
Filed: 1975-07-23
Abstract: The element consists of a radiation-transparent base (10), a reagent layer (16) permeable to the substance to be analysed, and a registration layer (12) arranged between the reagent layer and the base. The reagent layer contains a substance which causes a reaction with the substance to be analysed so as to form a dye. The purpose of the registration layer is to make it possible to detect the dye, e.g. by means of radiometry. The element further contains, between the reagent layer and the registration layer, a permeable radiation barrier layer (14) and/or an isotropic, porous distributing layer over that side of the reagent layer which faces away from the base. The element can be used particularly advantageously for the diagnostic analysis of biological fluids, e.g. blood, blood serum and urine. <IMAGE>

Title: Improvements in valves for internal combustion engines
IPC: F01L3/22
Filed: 1923-12-12
Abstract: 230,194. Howard, H. J. Dec. 12, 1923. Valves.-In a split sleeve valve 8 reciprocating between the cylinder and cylinder head, leakage along the split portion is prevented by forming square teeth along the opposing edges and arranging so that the teeth along one edge are pressed in an axial direction against the opposing teeth, for example by forming opposing teeth out of line so that they require to be sprung into engagement, or by forming one side of the split more flexible than the other and allowing the former to be pressed against the latter by the cylinder pressure. This difference in flexibility may be obtained, where the valve is formed with two lugs A for attachment to the valve gear, by arranging the split nearer to one lug than the other. The cylinder head is fitted' with two packing-rings B surrounding a broad packing-ring C. In four-stroke engines, the inlet may take place through a valve 3 in the head so as to have a cooling action on the sleeve valve; but in twostroke engines, the inlet is by terminal ports.

Patent GB-314555-A (GB)
Abstract: 314,555. British Celanese, Ltd., Green, S. J., and Widdowson, R. R. Jan. 28, 1928. Acetic and other aliphatic anhydrides are produced by passing the vapour of an acid such as acetic acid over tungstic acid or a tungstate other than an alkali tungstate. Alkaline earth and magnesium tungstates are particularly suitable. The catalyst may be supported upon pumice, kieselguhr, or carborundum and the apparatus may be a tube made of or lined with silica, copper, sold, silver, graphite, or nickel chromium steel. The catalyst may be heated electrically, reduced or increased pressure may be employed, and indifferent gases such as nitrogen or carbon dioxide may be mixed with the vapour. The anhydride may be separated in any suitable way, for instance, by mixing with the vapour of an entraining liquid such as benzene, carbon tetrachloride, petrol, mixture of such substances, or mixtures of ether and petroleum ether, as described in Specification 303,772, the water vapour being carried off by the vapour of the entraining liquid, while the anhydride condenses; or the vapour may be led under the surface of an extracting liquid such as benzene, chloroform, or mixtures of ether or chloroform with one or more hydrocarbons such as light paraffins, gasoline, kerosene, benzene, or its homologues, as described in Specification 298,667; or the vapours may be subjected to condensation by impinging upon a flowing stream of benzene or other waterinsoluble solvent for the anhydride, as described in Specification 310,863; or the anhydride may be separated by fractional condensation as described in Specification 256,663. When increased pressure is used, the pressure is preferably released before the separation of the anhydride. The initial material may be dilute or concentrated, and the waste liquor obtained in the acetylation of cellulose may be emploved. A suitable catalyst may be made by mixing solutions of calcium chloride and sodium tungstate and repeatedly extracting the precipitate with water, after which it is dried and used as such or upon pumice or other carrier. Examples describe the treatment with this catalyst of vapour of glacial acetic acid or of a mixture of carbon dioxide and acetic acid produced by passing carbon dioxide through hot or boiling acetic acid, the product being caused to impinge upon a stream of benzene.

Abstract: 618,133. Axial-flow pumps; elastic-fluid turbines; stuffing-boxes. AKTIEBOLAGET COTAVERKEN. Oct. 24, 1946, No. 31612. Convention date, Jan. 25. [Classes 110 (i), 110 (iii) and 122 (v)] An arrangement in compressors driven by turbines particularly for power plants in which the turbine is driven by exhaust steam from a multi-stage reciprocating steam engine and in which the compressor is used for compressing the steam between some of the expansion stages of the steam engine, is characterised in the provision of means for supplying leaking steam from at least one of the shaft packings of the compressor as sealing steam to one or more packings of the turbine and if desired to the steam inlet of the turbine. Conduits 9, 11 supply steam leaking from the packings 6, 7 of the compressor 1 to the packing 8 of the turbine 2 via conduit 12. An automatically adjustable valve 10 which is controlled by the steam pressure in the conduits 9, 11 and 12 admits steam to the inlet 2 of the turbine via conduit 20 if the pressure is too high and allows live steam to be admitted via conduit 19 if the pressure is too low. Live steam may also be admitted to the ejector 22 to draw off any excess of steam from the outer ends of packings 6, 8.

Filed: 1967-07-11
Abstract: 1,195,064. Typewriters &c. INSTITUTE FOR SCIENTIFIC INFORMATION. 11 July, 1967, No. 31787/67. Heading B6F. [Also in Division G4] Copy-verifying apparatus indicates when a difference exists between electric signals respectively representing the characters of a script and of a copy of it, and uses optical scanning means to produce the second signal. A hand-held reading head is moved across characters to be copied from a document, a vertical strip of character being imaged on to a column of photo-cells in the head. A character recognition device receives an indication of head speed from the head together with the photocell outputs over a flexible cable, and prints out the recognized characters on a typewriter. The typewriter keys can be actuated manually to insert corrections of characters skipped in the reading. In an alternative mode of operation, a typed copy may be checked against the original by inserting the copy in the typewriter, and actuating the typewriter keys in accordance with the original but with the actual printing disabled, the key identities being fed to a comparator for comparison with the character identities from the character recognition device, the reading head being positioned to read the characters on the copy coming into the printing position of the typewriter. Inequality actuates an alarm. Alternatively, the original could be typed over while the copy is being scanned by the reading head, the key identities being compared with the recognition device output. Alternatively, two reading heads could be employed, one scanning the document in the typewriter as the space bar is repetitively pressed and the other scanning another document, the character identities being automatically compared. A guide may be provided for the reading head.
