Title: Method and device for manufacturing needles for fibrillating rollers
IPC: B21G1/00
Filed: 1972-03-17
Abstract: 1382666 Making needles; breaking NETHERLANDS APPLIED SCIENTIFIC RESEARCH FOR INDUSTRY TRADE & COMMERCE 17 March 1972 [19 March 1971] 12630/72 Headings B3A and B3E A thin metal needle having a point at at least one end for a roller for fibrillating plastics films is made by feeding a continuous wire 28 between a first pair of driven rollers 3, 4 and a second pair of rollers 11, 12 driven at a faster speed than the first pair 3, 4 so as to exert an increasing tensile stress on the wire 28 and, after a certain period of time, breaking the wire 28 to produce a point by passing an electric current through it. The roller pairs are electrically insulated from each other and connected to a current source 26 via a relay 24 so that when the leading end of a tungsten wire 28 of 50 Ám diameter is engaged by the second roller pair 11, 12 an electrical circuit is closed. After a time interval determined by the relay 24 the wire is heated by electrical current causing it to break when it reaches a temperature at which the tensile strength of the wire 28 corresponds to the stress produced in the wire 28 by the faster moving rollers 11, 12. The time interval from the engagement of the wire 28 by the rollers 11, 12 to the heating of the wire 28, which determines the stress in the wire 28 and hence its breaking temperature, is controlled by a resistor 31 of the relay 24. The needle 34 produced is removed from the apparatus by the rollers 11, 12, the cycle being repeated when. the leading end of the wire 28 is again engaged by the rollers 11, 12. Argon is passed through a glass tube 19 via an inlet 22 such that the temperature rise of the wire 28 is fastest at a position, where the wire breaks, midway between the inlet 22 and the lower end 21 of the tube 19.

Title: Improvements in and relating to the modification of organic isocolloids containing high molecular acids
IPC: C09F5/00
Filed: 1929-04-24
Abstract: 337,735. Auer, L., and Susztek, L. April 24, 1929. Fats and fatty oils; waxes; fatty acids. - The physical properties of organic isocolloids consisting of or containing high molecular organic acids such as fatty oils, resins, naphthenic acids, or waxes, are modified by heating and dispersing soaps of the alkali or alkaline earth metals (including zinc and magnesium) in the said isocolloids, and subsequently vulcanizing the modified product. The step of dispersing the soaps in the isocolloid may be effected by rubbing or kneading the soap therein at low temperature and in the presence of a dispersing agent for the soap e.g. water or benzene. In examples, (a) the potassium or sodium soaps of linseed oil fatty acids are heated with linseed oil and the product is vulcanized by heating with sulphur to which has been added mercaptobenzthiazole and zinc oxide, or by stirring with sulphur chloride, (b) a mixture of linseed and wood oil is kneaded with a solution of the zinc soap of linseed oil fatty acids in benzene. After heating, the modified product free from organic solvents is treated with a solution of sulphur chloride in turpentine. The products are viscous oils or semi-solids and are used as bases for the manufacture of varnishes or rubber substitutes. The unmodified isocolloids may be replaced by those modified for example, by salts, peroxides, alkali metals or oxides, or by compounds comprising an organic residue united to an inorganic acidic residue (e.g. benzene sulphonic acid) as described in Specifications 287,943, 321,690, 321,691, and 321,724 respectively, to yield a product of a double mcdification. The reaction mass may be made part of an electric circuit as described in Specification 321,689 or may be submitted to a gas treatment as described in Specification 287,943, to irradiation such as ultraviolet or X- rays, or organic metal-free secondary reagents e.g. ketones or phenols, may be added thereto. Specifications 2878/86, [Class 95. Paints &c.], 12795/88, 267,174, 275,574, 289,414, 289,415. 321,722, 321,723, 321,725, 321,726; and 321,727. [Class 95, Paints &c.], also are referred to.
