Title: Improvements in and relating to record discs for talking machines and the like
IPC: C08L93/02
Filed: 1923-10-19
Abstract: 221,105. Forse, W. T., and Columbia Graphophone Co., Ltd. Oct. 19, 1923. Records, blanks for.-Relates to disc records for gramophones and the like, and consists in making a thermoplastic powder for producing the surface layer of such records by finely powdering a homogeneous mass in which shellac is combined, without fibrous binding material, with one or more mineral earths or the like, together with other resins and colouring matter. The powder is ground to such a degree of fineness that no particle exceeds 0.1 mm. in diameter; the size is preferably not more than two-fifths of the pitch distance between consecutive turns of the sound record groove. In making the records, paper sheets are preferably used, being coated with the thermoplastic powder and secured to a backing or core of any suitable cheap material. A preliminary treatment of the coated sheets may be given by passing them, whilst warm, between cold rollers. The finer powder may be produced in the following manner. After mixing the ingredients, heating and rolling the mixture into slabs, and then powdering in the usual way, the powder is fed from the grinding mills into a separating box at the top of which a suction fan is mounted. The very fine particles are drawn off by the air current and collected, while the larger ones fall to the bottom of the chamber, whence they are returned to the grinding mills.

Title: A method and apparatus for teh correlated analysis and identification of samples
IPC: G01N35/02
Filed: 1964-06-24
Abstract: 1,055,235. Collecting blood. TECHNICON INSTRUMENTS CORPORATION. June 24. 1964 [July 30, 1963], No. 26180/64. Heading A5R. [Also in Divisions Bl, B8 and G1] A blood donation receptacle 21 and a sample cup 34 are connected by a strip 33 which bears in several places a donor identity number 42 and a code 43 representing the same number in a form such as punched holes, varying opacity or localy magnetised parts of an oxide film. Receptacle 21 and cup 34 are filled at the same donation and strip 33 is severed at line 44. Sample cups are loaded on a sample plate (52) (Fig. 4, not shown) with strips 33 projecting (Fig. 3, not shown), and plate (52) is indexed to bring successive cups under sample take off crook (62), whereby samples are drawn into automatic analyser (63) and analysed using anti-serum to determine groups. The result of each sample analysis is recorded on a moving chart (76) in terms of four traces produced by pens (69), (71), (72), (73). The descent of crook (62) actuates a mercury switch (91) which actuates a solenoid moving detector (81) to 'read' the code 43 on the adjacent strip 33, the code 43 being thus printed as a number (84) on chart (76). The analysis time is equal to the time taken for a cup 34 to move from crook (62) round to detector (81) so that the number (84) is printed adjacent the traces representing the corresponding sample on chart (76). Thus the receptacle 21 and a chart portion bearing the corresponding analysis bear the same identity number.

Title: Manufacture of new 3-amino-indanes
Filed: 1954-09-15
Abstract: The invention comprises 3-amino-indane derivatives of the formula <FORM:0793852/IV (b)/1> in which R indicates hydrogen or a low alkyl radical, i.e. containing 1 to 4 carbon atoms, R1 indicates a low alkyl radical and Am is an unsubstituted amino group or an amino group mono- or di-substituted by low alkyl radicals, or a group attached by nitrogen which is a member of a 5- or 6-membered saturated heterocyclic ring.  Such compounds are obtained when (a) 3-halogen-indanes appropriately substituted in the 1-position are reacted, preferably in the absence of water, with ammonia or an appropriate primary or secondary amine; or (b) a 3-keto indane appropriately substituted in the 1-position is either (a ) first reacted with hydroxylamine to give its oxime and the latter then reduced to the amine; or (b ) directly subjected to reductive amination in the presence of ammonia or a corresponding primary or secondary amine, whereupon, if desired, the primary or secondary amine obtained according to one of the specified methods is converted by N-alkylation into the finally desired N-substituted 3amino-indane. The 1-substituted 3-halogenoindanes can be obtained by catalytic reduction of the corresponding indane-3-ones, and reaction of the indane-3-ols produced with halogenating agents such as thionyl chloride.  As amines for the introduction of the group Am there are mentioned mono- and di-alkylamines, piperidine, pyrrolidine, morpholine, oxazolidine, thiazolidine and piperazine.  In examples: (2 and 3) 1:1-dimethylindanone-(3) oxime (prepared from the ketone) is reduced to 1:1-dimethyl-3-aminoindane with palladium black and Raney nickel respectively.  In further examples there are prepared by hydrogenation of a mixture of the appropriate indanone and the amine or ammonia (1) 1-methyl-3-methylamino - indane; (4) 1:1 - dimethyl - 3 - aminoindane.  In Example (5) 1:1 dimethyl-3-aminoindane is dimethylated with formic acid and formaldehyde.

Abstract: 1,133,732. Flame-retardant polyesters. ALBRIGHT & WILSON (MFG.) Ltd. 2 Aug., 1965 [6 Aug., 1964; 2 Feb., 1965], Nos. 26793/65 and 4520/65. Addition to 1,115,043. Headings C3P and C3R. A flame-retardant polyester contains units wherein each X is a halogen atom and R is a hydrocarbon or substituted hydrocarbon group. The polyester may be prepared by condensing a mixture of the acid and the acyldiphosphonic acid with, usually, an additional polycarboxylic acid and at least one polyhydric alcohol, or the acyldiphosphonic acid may first be converted into a hydroxyalkyl ester and used as the polyhydric alcohol. The preferred halo-acid is chlorendic acid. Suitable acyldiphosphonic acids are acetyl-(R=CH 3 ), propionyl-, phenylacetyl-, p-chlorophenylacetyl-, chloracetyl- and octoyl-diphosphonic acids. Preferred hydroxyalkyl derivatives are those of the formula wherein R<SP>1</SP> is a hydrocarbon or substituted hydrocarbon group or a group and R<SP>11</SP> is H, CH 3  or halomethyl, m is 0-20, n is 1-20, and at least one group Q is H, any remaining being an alkyl or acyl group. The functionality of the diphosphonic compound may be controlled by partial esterification of the acid with a monohydric alcohol (including an alkylene or polyalkylene glycol monoether) or by partial acylation of the hydroxy groups in the acid or the hydroxyalkyl derivative. Other polyester components suitable for use in the present invention are phthalic, succinic or maleic anhydride and ethylene glycol, glycerol, trimethylolpropane, polyethylene glycol and butene-1:4-diol. In examples maleic anhydride, phthalic anhydride, chlorendic anhydride and ethylene glycol are condensed with acetyldiphosphonic acid or its condensate with epichlorhydrin or propylene oxide. Where unsaturated components are used in preparing the polyester, the product may be copolymerized with a vinylic compound, e.g. styrene, preferably amounting to 10-30 wt. per cent of the polyester, i.p.o. benzoyl peroxide and cobalt naphthenate. In the examples the product polyesters are copolymerized with 20 wt. per cent of styrene.

Abstract: 1,173,868. Valves. AMERICAN METER CO. 5 June, 1968 [2 Jan., 1968], No. 26860/68. Heading F2V. A valve includes a stationary casing 12, a stem 20 and a diaphragm 51 mounted for axial movement within the casing, means preventing leakage between the floating member and the casing, trigger means 33 normally preventing downward movement of the stem independently adjustable first and second springs 73, 74 exerting a downward force on the diaphragm, the movement of the spring 73 being limited by flanges 77, 78, means 59, 60 for releasing the trigger upon predetermined movement of the diaphragm in either direction, and a spring 75 to move the stem axially downward upon release of the trigger. The pressure at 14 in the valve body is communicated through passages 28, 28a to the lower face of the diaphragm 51 and upon a sufficient increase in value compresses the spring 74 until a stirrup 60 rocks the trigger 33 about a pivot 40, moving a stop 41 free of a cam member 22 to permit the valve to close. To reset the valve, a cap 81 is removed and a key (not shown) screwed on to the upper part of the stem. The trigger and stem are also released when a sufficient fall in pressure permits the spring 73 to depress a projection 59 into contact with the trigger. A pull rod 43 permits manual release of the valve and a fusible plug 48 causes closure in response to a predetermined temperature rise. Leakage past the diaphragm at a higher rate of flow than that permitted by a vent 82a also actuates the release mechanism. In a modification, the released stem opens a normally closed valve held against a downwardly facing seat by a spring.
