Patent GB-420632-A (GB)
Title: Process for the manufacture of female sexual hormone
Filed: 1934-01-12
Abstract: Female sexual hormones are obtained from the urine of stallions by heating the slightly acidified urine, cooling and extracting with an organic solvent e.g. ether, washing the extract with sodium carbonate solution and then with water, evaporating the solvent and purifying the extract in the usual manner.  Reference has been directed by the Comptroller to Specification 392,039.
Patent GB-727882-A (GB)
Title: Improvements in and relating to textile materials
Inventor: HUNT RICHARD EDWIN
IPC: D06M13/152
Filed: 1950-01-17
Abstract: Fabrics of regenerated cellulose are rendered crease-shedding, wet crease-resisting and dry crease-resisting by treating them, while free from substantial actual crease marks and in open width, with a swelling agent for regenerated cellulose at a concentration and temperature such that the regenerated cellulose swells without substantial damage, maintaining the fabrics in contact with the swelling agent, in open width and under as little tension as possible and without creasing, until they have been rendered crease-shedding and wet-crease-resisting, and then rendering them dry crease-resisting by condensation of a thermosetting resin within and substantially not between the fibres or by treatment with acid and formaldehyde or acid and glyoxal.  Specified swelling agents are aqueous solutions of sodium hydroxide, potassium hydroxide, sodium zincate and benzyl trimethylammonium hydroxide or mixtures thereof, aqueous zinc chloride and aqueous mineral acids, e.g. nitric and sulphuric acids.  Controlling agents, e.g. sodium chloride, sodium silicate or sodium phenate, may be added to the aqueous alkali metal hydroxide solutions or formaldehyde to the aqueous sulphuric acid. The dry-crease resisting process may be effected by application of solutions of methylol urea, e.g. as prepared in Specification 449,243, or methylol melamine or alkylated derivatives thereof together with acid or potentially acid catalysts, followed by drying and heat-curing, if desired in the presence of steam. Natural or synthetic rubber, stearamidomethyl pyridinium chloride, octadecyloxymethyl pyridinium chloride, paraffin wax emulsions and the polysiloxanes of Specification 695,703 may also be incorporated with the resin solutions.  During or after drying, the impregnated fabric may be subjected to mechanical effects, e.g. calendering, Schreinering, embossing, glazing and pleating. Numerous examples are given, in one of which the fabric contains wool, and in another nylon, in addition to regenerated cellulose. Specifications 727,881, 727,888, 727,889 and 727,890 also are referred to.  In the first Provisional Specification the process is stated to be applicable to fibres and yarns as well as to fabrics, and also to textiles of native cellulose, e.g. cotton, cellulose acetate, wool, silk and nylon, the swelling agents being, for wool, sodium bisulphite, calcium thiocyanate, phenol, acids and steam; for cellulose acetate, thiocyanates, acetic acid, methyl alcohol, acetone, ethers of ethylene glycol and phenol; for nylon, phenolic substances, acids and steam; for methylol polyamides, alcoholic solvents; and for silk, inorganic acids.

IPC: D06M13/313
Filed: 1954-01-19
Abstract: Textile materials, which may be tows, yarns, staple fibres or woven or knitted fabrics of viscose rayon, cotton or regenerated protein, are treated with an aqueous solution containing a vinyl ester of a phosphorus-containing acid, or an ester of a phosphorus-containing acid which will decompose upon heating to yield a vinyl ester, and the materials are subsequently heated. The vinyl ester may be divinylamino phosphonate (CH2=CHO)2P(O) (NH2), divinyl methyl phosphonate, divinyl ethyl phosphonate, trivinyl phosphate, a vinyl ester of a poly-phosphorus acid or a sulphur analogue thereof, e.g. divinyl amino thiophosphonate (CH2=CHO)2P(S) (NH2).  Specified compounds which will yield such an ester on heating are b -hydroxy-, b -amino- and b -chloro-ethyl esters of phosphorus-containing acids such as bis-2-chloro-ethyl-amino phosphonate (ClCH2CH2O)2P(O)(NH2) and bis - 2 - hydroxy - ethyl - amino phosphonate (HOCH2CH2O)2P(O)(NH2).  The treating solution may contain a catalyst. In examples, viscose rayon and cotton fabrics are treated and the catalysts are sodium and potassium carbonate and sodium hydroxide. After treating with the aqueous solution the fabrics are dried, in some cases on a pin stenter, and are baked at temperatures ranging from 140 DEG  to 190 DEG C. The aqueous solutions may also contain sodium chloride or ethyl alcohol.

Title: Improvements in or relating to data propagating apparatus
IPC: G06F11/16
Filed: 1967-01-12
Abstract: 1,112,490. Error detection. INTERNATIONAL BUSINESS MACHINES CORPORATION. 12 Jan., 1967 [17 Jan., 1966], No. 1669/67. Heading G4C. Error checking means comprises means for adjusting check bits of data bytes prior to storing the bytes and means for presenting data with detected errors to the storage means a second time with selected bit inversions. Seven-bit bytes (each including a parity bit) are read from tape into computer storage, each with two extra bits (normally zero) adjointed thereto. A parity check is performed on each byte as it is read from the tape. In the case of error, the parity bit is inverted before being written into the computer storage, and the record in which the byte occurs is re-read from the tape into another part of the computer store, one of the extra bits referred to in the erroneous byte being set to " one " this time (but the latter does not happen if the byte is now error-free). Later, a comparison of the extra bits in the two versions of each byte in a repeated record enables the bytes in which an error was detected to be printed out for human correction. The tape bytes may have 9 bits in which case no extra bits need be adjoined before storage. The invention may be applied alternatively to recording on to one or more tapes.

Abstract: 574,578. Tyre valves. DUNLOP RUBBER CO., Ltd., POWELL, E. F., and BADHAM, P. W. Feb. 2, 1943, No. 1692. [Class 135] [Also in Group XXXIV] A tubeless pneumatic tyre 3 is sealed by air pressure deforming the sides 1b of an inflatable annulus 1 against the tyre insides, the annulus 1 having an inextensible outer wall periphery 1d having at least one air inlet or non-return valve 8, the inner wall periphery 1a of the annulus seating on the rim and having an inflation opening to the inflation tube 5 and with the usual inflation valve. The side walls 1b carry sealing coatings of plastic non-drying or tacky material, e.g. a mixture of reclaimed rubber, whiting, clay, &c., and held in place by circumferential ribs 1c. The outer periphery 1d of the annulus 1 is made circumferentially inextensible by cords 9 and/or fabric, the cords being held in position by rubber so that they can spread apart transversely. A spring- pressed, non-return valve 6 allows air to pass from the annulus to the tyre after the edges have been sealed by deformation. Fig. 2 shows a combined inflation and release valve in which inflation flattens the rubber cup 11d over the ports 11c and so distends the sides 1b to seal the tyre. Further inflation raises the disc 11g against its spring 11e and allows air to enter, the tyre. Opening the external inflation valve (not shown) allows complete deflation.
