Title: Polymers of a fluorine-containing ester of methacrylic acid and their use for treating fibrous materials
IPC: D06M15/277
Filed: 1964-06-16
Abstract: Perfluoroheptyl-methyl methacrylate is prepared from methacrylic acid and C7F15CH2OH.ALSO:The invention comprises polymers of per-fluoroheptyl-methyl methacrylate containing <FORM:1045896/C3/1> as the repeating unit.  These may be produced by known emulsion polymerization techniques from the monomer, and may be used for treating fibrous materials (see Division D1), e.g. in solution in fluorinated organic solvents such as trifluoromethyl benzene, bis-(trifluoromethyl) benzene and methyl perfluoroacetate.ALSO:Cotton, paper and leather are treated with a polymer of perfluoroheptyl-methyl methacrylate (see Division C3), and the treated material maintained at a temperature up to 190 DEG C. to obtain a fluorine content of 0.05-5%.  The polymer may be applied by padding from aqueous emulsion or solution in a fluorinated organic solvent such as trifluoromethyl benzene, bis-(trifluoromethyl) benzene and methyl perfluoroacetate.  The material treated is thereby rendered repellent to water, oil, soiling and staining.

IPC: A61M5/34
Filed: 1927-09-23
Abstract: 302,974. Hein, G. N. Sept. 23, 1927. Syringes.-In hypodermic syringes in which the needle 12, Fig. 1, is provided with a socketed base 13 frictionally engaging a tapered spigot 11 on the barrel 10 additional meens of a resilient nature are provided to retain the needle base 13 in position. As shown, the means comprises a coil spring 14 the outer coils of which are caused to expand over the. member 13, thus tightening the remainder of the spring on the spigot 11. The member 13 is formed with a helically-cut end 15 and with a radial projection 16 engaging the spring and expanding it on rotation of the member 13. Alternatively, the end of the member 13 may be cut away completely except at the part 16. In further modifications, the member 13 or the spigot 11 may be formed with a helical groove for engagement by the spring 14 or the spring may be secured within a sleeve into which the member 13 is screwed. As shown in Figs. 11 and 12, one end of the spring 29 is formed with a projecting resilient arm 30 engaging a groove 31 in the member 13. Alternatively, each end of the spring may be formed with such an arm. In Fig. 16, the spring is replaced by a screw socket 38 engaging a screw thread on the spigot. In a further modification, the resilient arm 39, Fig. 16, may be replaced by a number of resilient members formed by longitudinally splitting an internally-threaded sleeve,

Patent GB-748372-A (GB)
Title: A method for inactivating metallic powder
IPC: C06B21/00
Filed: 1953-09-11
Abstract: Metallic powders are inactivated by coating with a heavy layer of oxide, of greater thickness than that formed by oxidation in air at ordinary temperature, and then impregnating with a fatty acid having more than ten carbon atoms in the molecule.  Oxidation may be effected by means of an oxidising liquid by heating in a mixture of rare gas and oxygen, or by heating in air e.g. at 400 DEG -600 DEG C. for Al, at 300 DEG -400 DEG C. for Mg, or at 200 DEG -300 DEG C. for Zn; the oxidised powder may then be cooled in water and dried prior to impregnation.  The acid may be stearic, palmitic or oleic and may be applied in organic solvents such as benzene and alcohol mixtures. The powder may be pickled before oxidation e.g. in aqueous nitric acid for Al, in ammonium chloride solution for Mg. or in oxalic acid solution for Zn.

Abstract: 659,557. Cigarette cases. JOHNSSON, G. R. Oct. 6, 1949, No. 25695. [Class 18] [Also in Group XI] Cigarettes 2 in a magazine fall singly past a leaf spring into a trough or shoot 3 pivoted on a spindle 4 journalled t o the magazine sides. When the shoot 3 is rocked downwards the leaf-spring is engaged by the rear edge of the shoot and prevents the next cigarette coming down while the cigarette in the shoot rolls into a bridge piece 7 carrying an electrical filament 6 at one end. The bridge 7 is then rocked into a substantially upright position about a pivot 9 at right angles to the spindle 4 and the cigarette therein falls by gravity on to the filament 6 which is energized when the electrical circuit is closed by means of a contact strip 11. In a second embodiment, the edge of the shoot 3 is located in front of the leaf-spring and the shoot is then rocked upwards to feed a cigarette out of the magazine.

[Class 87 (ii).] In apparatus for making concrete pipes or tubes of the kind in which the pipe or tube is spun by a core 3 rotated in a mould 10 and having helical vanes or ribs 3a on its circumference, the pipe or tube is constructed against the resistance of a hydraulic ram 5. The ram 5 carries a rotatable table 8 provided with four apertures over one of which the mould 10 is placed. The core 3, which is the same length as the mould, is carried by a shaft 2 rotated by a motor 4. For the purpose of feeding concrete to the mould, the shaft 2 is hollow and is provided at the lower end with perforations 2<a>. A second core 13 provided at the upper end with a collar-forming flange 13a is mounted above the core 3 and is carried by a shaft 12 driven from the shaft 2 by gear wheels 11, 11. In use, a mould 10 is placed over one of the apertures in the table 8, the table is rotated to bring the mould under the core 3, and the ram is actuated to raise the mould until the ribs or vanes 3a are at the lower part of the mould. Concrete is then admitted to the mould and the core 3 rotated, the table being forced down against the resistance of the ram as the concrete is compressed. When the formation of the pipe or tube body is completed, the table 8 is rotated to bring the mould containing the body beneath the core 13, a second mould being simultaneously brought beneath the core 3. The ram is then again raised and subsequently forced down during which movements a collar is formed on the already formed pipe or tube body by the flange 13a, and a second body is formed by the core 3. The table is then further rotated and the finished pipe or tube removed.
