IPC: C08K5/13
Filed: 1943-02-13
Abstract: In order to facilitate the dispersion of compounding-ingredients such as carbon black in a synthetic rubber of the butadiene class, an agent for reducing the surface tension between the synthetic rubber and the ingredients is added. Monoethanolamine stearate, cyclohexyl ammonium cresylate, a phenol, or a substituted phenol having the hydrogen in one or more of the OH groups replaced by an organic radical or radicals may be employed.  In an example, 15 lbs. of monoethanolamine stearate and 135 lbs. of carbon black are added to 300 lbs. of butadiene/styrene rubber.

Abstract: 866,213. Photo-electric detection of spacing faults. POWELL, G. F. W., CROSLAND, R. G., and MOLINS MACHINE CO. Ltd. Jan. 27, 1958 [Jan. 25, 1957], No. 2754/57. Class 40(3) In apparatus for detecting spacing faults in a succession of workpieces, e.g. composite cigarette rods, moving in spaced relationship, a photoelectric detector 1, Fig. 4A, produces a voltage pulse when the trailing edge of a workpiece moves out of the light beam illuminating its cell and a second photo-electric detector 2 allows the passage of the pulse to maintain a control circuit keeping the moving mechanism in operation only if the light directed on its cell is obscured by the leading edge of a following workpiece. The voltage pulse produced by cell 12, Fig. 3A, of detector 1 passes via transformer 14 to the voltage dividing circuit, resistance 15 and cell 16 of detector 2. If cell 16 is obscured its resistance is high and the pulse amplitude exceeds the bias on diode 17 whereby the pulse passes via conductor O to the control circuit. When, due to a spacing fault, cell 16 is not obscured the pulse amplitude is insufficient to exceed the diode bias and the absence of a pulse on conductor O switches off the moving mechanism.

Title: Dye-receptive graft copolymers, method for preparing same and shaped articles fabricated therefrom
IPC: D06M14/34
Filed: 1959-01-27
Abstract: Dye-receptive graft copolymers comprise a superpolyamide substrate having chemically attached thereto a minor proportion of substituent graft copolymerized units of an ethylenically unsaturated monomer which in polymeric form confers dye affinity on the resulting product, e.g. vinyl lactams, sulphonated alkenyl aromatic monomers, sulphonated olefin monomers, sulphonated acrylic and methacrylic esters and N-alkyl substituted amides, vinyl pyridines, aminated alkenyl aromatic monomers, aminoalkyl esters of acrylic and methacrylic acids, polyglycol ethers of alkenyl aromatic compounds, polyglycol monoesters of acrylic and methacrylic acids and N-vinyl-3-morpholinone.  Mixture of such monomers may be used.  The process is preferably applied to the polyamide in shaped, e.g. film or fibre, form employing the monomeric material in undiluted form or in solution, e.g. in water.  The polymerization of the monomer may be carried out in any one of the following ways:- (a) by use of a free-radical catalyst, e.g. hydrogen peroxide, benzoyl peroxide, cumene hydroperoxide and ammonium or potassium persulphate, (b) by subjecting the monomer-impregnated substrate to high-energy irradiation, e.g. beta or gamma radiation, electron beams and X-rays, (c) by subjecting the substrate to high energy irradiation or ultra-violet light and then contacting with monomer, and (d) preactivating the substrate by exposure to ozone or ultra-violet light and oxygen.  The examples describe the graft polymerization of the following monomers on to fibres made from 66-nylon: (1) p-styrene sulphonic acid sodium salt, (2) a mixture of methylene-bis-acrylamide and ethylene sulphonic acid, (3) a mixture of vinyl pyridine and p-styrene sulphonic acid sodium salt, (4) dimethylaminoethyl methacrylate, (5) 1-(2-methoxyethoxy)2-vinyl-benzyloxy-ethane, and (6) the methacrylic ester of the methyl ether of polyethylene glycol 600. Reference is also made to the use of substrates made from polycaprolactam.  Reference has been directed by the Comptroller to Specifications 872,513 and 872,514.

Title: Improvements in or relating to carbon articles and methods of producing the same
IPC: C25B11/12
Filed: 1938-01-29
Abstract: 510,256. Making carbon articles. WILLMORE, C. B. Jan. 29, 1938, No. 2903. Convention date, Jan. 30, 1937. [Class 90] Carbon articles, such as electrodes, are obtained by mixing in the cold, particles of carbonaceous material, a finely divided solid binder which will carbonize to give an electrically conducting residue, and a solvent for binder sufficient to act on the surface of the particles but insufficient to soften the binder and to destroy the granular nature of the mixture. 'The resulting mixture is then shaped under pressure without the use of heat. The temperatures used, e.g., 5-40‹C. are insufficient to soften the binder, although heated moulds may be used. The carbonaceous material comprises graphite, petroleum, coke, calcined anthracite, pitch coke or metallurgical coke and the binder melts between 60‹ and 200‹C., e.g. coal tar pitch; petroleum pitch, resin or synthetic resins. Suitable solvents include creosote oil, benzol, pyridine, nitrobenzene, -o-nitrotoluene, furfural, acetone, turpentine, aniline, butyls alcohol, naphthae, chlorinated compounds such as carbon tetrachloride, monochlorbenzene or dichlorpentane, or mixtures. 'The solvent is preferably added to the mixture of carbon and binder while stirring and the product then moulded under a pressure of 5,000-15,000 lbs/sq. in. and are finally baked in the usual manner. Other articles which may be made include generator brushes, and linings for various types of vessels. According to an example, "green" electrodes having a density of 1.45 were made from a mix of 1,360 lbs. coke aggregate, 240 ground coal tar pitch and 4.8 gallons of dichlorpentane moulded under a pressure of 6,250 lbs/sq. in. 'They were then baked at 1,000‹C. for about 24 hours. The density of the final electrodes was about 1.40.

[Also in Groups XIII and XXVIII] Oxygen from a tube 2 is passed into molten pig iron in a steel converter 1 and the gases from the vessel are collected in a hood 3 (see Group XXVIII) and pass to a conduit 7 in which they are cooled (see Group XIII) by gas or steam, the injection of which is controlled according to the pressure in the hood 3, detected by tubes 11, so that the pressure at the bottom of the hood is maintained equal to that of the surrounding atmosphere and contact of the gases with the air is kept at a minimum. The three pressure tubes 11 at one level in the hood 3 and a reference tube 12 outside the hood communicate with an electric switching device 13 coupled to a pressure-measuring device 14. Cams in the device 13 cause consecutive communication of the tubes 11 with a chamber of the device 14, another chamber being permanently connected to the tube 12 to detect pressure differences. The device 14 passes a signal to a potentiometer 15 which adds integral and differential components and acts on pneumatic relays 17 and 18 to regulate a valve 19 controlling the flow of cooling gas or steam and to move a pneumatic slide 10 and an injector 9 for the cooling fluid, with respect to a Venturi tube 8, to determine the flow and entraining of the gases. In Fig. 4 (not shown), there is no Venturi and the entraining of the gases to be cooled is controlled by regulation of two opposed injectors for the cooling gas or steam, along the axis of the conduit 7 as in the ease of the injector 9. There may be an auxiliary fan.
