Patent GB-924815-A (GB)
Title: Improvements in methods of preparation of polypeptides of spasmolytic activity
IPC: A61K35/26
Filed: 1959-12-24
Abstract: Polypeptides having spasmolytic activity are obtained from animal organs of lymphoidal structure e.g. lymph ganglions of oxen or sheep or calf or lamb thymus, by hydrolysing the comminuted organs to a broth by warming with an aqueous solution of a protease e.g. papain, heating the broth to destroy the enzyme, clarifying the broth and fractionally precipitating the polypeptide from the clarified broth with alcohol, the active material being recovered from the product precipitated with the greatest concentration of alcohol.  The hydrolysis may be carried out at 60 DEG  C. for 15 minutes at a pH of 7.0.  After filtration, the clarified broth may be treated with an equal volume of 90% ethanol, the precipitate discarded, and seven volumes of absolute ethanol added to precipitate the polypeptide. The crude polypeptide may be purified by solution in acetic acid and further precipitation with ether.  Further purification may be by dialysis against water or chromatographic adsorption on an aluminium oxide and/or cellulose column.

Abstract: 1,191,075. Moulding ferro-cement pipes. POLITECHNIKA WARSZAWSKA. 17 Sept., 1968 [18 Sept., 1967], No. 44020/68. Heading B5A. [Also in Division F2] A reinforced concrete pipe is cast by applying mesh reinforcement about a vertical core 2 which is provided with a detachably secured annular piston 3 at the lower end thereof which is a sliding fit within a vertical mould shell 4. The piston 3 is initially located within the upper end of the shell 4, and either the shell 4 is upwardly displaced or the core 2 is downwardly displaced as the apparatus is simultaneously vibrated, e.g. by means 8, as concrete from a hopper 6, detachably secured to the shell 4, fills the increasing volume of the mould space. After moulding is completed, the piston 3 is detached from core 2, and the hopper 6 is replaced by a ring which restrains the pipe during removal of the core 2, prior to ejection of the pipe from the shell 4.

Title: Improvements relating to a thermographic method of recording information
Inventor: VRANCKEN MARCEL NICOLAS

Abstract: 1,245,927. Thermographic materials and processes. AGFA GEVAERT. Sept.10, 1968 [Oct.2, 1967], No.44795/67. Heading G2C. A heat-sensitive material comprising a support coated with a water-permeable layer of hydrophobic thermoplastic particles dispersed in a hydrophilic binder, (a) a substance which absorbs visible light and/or infrared radiation to yield sufficient heat to render the layer less water-permeable, this substance being water-soluble or capable of being bleached by using an aqueous bleach and (b) a non-water-soluble and/or non-bleachable coloured substance or colour former which can produce a coloured compound on heating or by reaction with a colour reactant. The invention also relates to a thermographic process in which the heat sensitive material above but without substance (b) is imagewise exposed so that the heated areas are rendered less water-permeable but are still permeable and developed with an aqueous liquid or bleach, to remove substance (a) from both the heated and non-heated areas either simultaneously or in successive steps. Preferred substances (a) are silver and water-soluble dye salts. Colour proofs may be produced by coating a support with the heat-sensitive layer above containing carbon instead of substances (a) and (b), imagewise exposing to the black separation negative and developing to remove the unheated areas to leave a black image. This image is coated with a heat-sensitive layer containing a water-insoluble cyan pigment and two water-soluble dyes absorbing visible light. The material is imagewise exposed to the cyan separation negative developed with water to remove the unheated areas and also to remove the water-soluble dyes from the heated areas. This last process is repeated using layers containing magenta and yellow water-insoluble pigments to build up a four-colour proof. Alternatively, silver may replace the water-soluble dyes and the silver is finally removed from the three top layers of the colour proof by a bleach bath. The preferred heat-sensitive layers are those disclosed in Specification 1,139,891 and 1,160,221 and the exposure techniques disclosed in those Specifications are preferred in the present process.

Abstract: 1,168,759. Hollow polyester filaments. GLANZSTOFF A.G. 23 Sept., 1968 [23 Sept., 1967], No. 45083/68. Heading B5B. A polyester fibre, such fibre having a separate filament count of 3 to 15 denier, has a cavity volume of 10 to 30% and presents a two-dimensional crimping with 75 to 110 crimps per 10 cm. Preferably, the polyester is polyethylene terephthalate, the fibre has a cavity volume of 20 to 30%, and presents a two-dimensional crimping with 90 to 100 crimps per 10 cms. The fibres are made in known manner by spinning the polyester using a hollow filament spinneret, stretching, crimping by compression, heat-setting and cutting to staple length. In the example, polyethylene terephthalate is so spun to form a tow of filaments, having a separate filament count of 5 denier. Five tows are plied and stretched in steam at 150‹ C. The tow is then led through hot water to remove the spinning preparation, and a dressing applied. Several tows so pretreated are assembled and supplied to a compression crimping device, whereafter they are set at about 140‹ C. and cut to a length of 50 mm.

Abstract: 1,130,608. Jet looms. MACHINEFABRIEK L. TE. STRAKE, N.V. 3 Nov., 1965 [3 Nov., 1964], No. 46625/65. Heading D1E. A jet loom for inserting single wefts or "hairpins" has a picking nozzle 17 combined with a suction operated weft storage tube 4 having three separate channels 12a, 12b and 12c to accommodate long pick lengths. The tube 4 has pressure wave eliminators 14, cam operated suction valves 13 and axially movable cam operated roller 20a, 20b that selectively cover the entrance to the channels 12a to 12c. In use and during picking the yarn extends from a bobbin 7 through feed rollers 6 to a cutter and clamp 21 and is drawn into an auxiliary storage tube 8. After picking with the end held by the clamp 21 it is said that the yarn is drawn out of the tube 8 and into the tube 4 through a lateral opening 10. The rollers 6 selectively uncover the channels 13a to 13c so the yarn is successively drawn into a loop in each channel and then successively uncover the channels so that the first leg of the hairpin may be picked simultaneously with the opening of the clamp 21. During picking yarn is drawn into the tube 8 so that, after the first leg has been picked, the yarn extends from the selvedge, through the clamp 21 and into the tube 8. Suction is then again applied to draw the yarn into the tube 4. For picking the second leg of the hairpin the cutter and clamp 21 is operated to sever the yarn extending from the clamp 21 to the tube 4 so that it may be picked and to hold the yarn end extending to the bobbin 7 so that it may be drawn into the tube 8.
