Title: Improvements in or relating to interpolymers
IPC: C08F2/04
Filed: 1951-02-22
Abstract: Film-forming ternary polymers are obtained by polymerizing a mixture comprising 30 to 80 per cent of an alkyl acrylate, the alkyl group containing 1 to 4 carbon atoms, 10 to 65 per cent of a vinyl ester of an aromatic acid, the carboxyl group being attached to the nucleus, and 5 to 40 per cent of a monovinyl aromatic compound, the vinyl group being attached to the nucleus. In addition to or as a partial replacement for the lower acrylates, higher acrylates in which the alkyl group contains 5 to 10 carbon atoms may be used.  Specified vinyl aromatic esters are vinyl benzoate, chlorobenzoate, toluate, chlorotoluate, naphthoate and pyrocatechuate.  The monovinyl aromatic compound may be styrene, o- and p-methyl styrenes, vinyl naphthalene, and nuclear-substituted chloro- and methoxy-styrenes and vinyl naphthalenes.  A fourth mono-olefinic compound such as vinyl chloride, vinylidene chloride, vinyl acetate, diethyl maleate, acrylonitrile, higher alkyl acrylates, and furfuryl and tetrahydrofurfuryl acrylates may be present, but three components only are preferred.  Polymerization may be effected in bulk, solution or emulsion in the presence of the usual emulsifiers or protective colloids.  When the interpolymer is to be used as a coating material, the medium is preferably an organic solvent in which both monomer and polymer are soluble, e.g. ethyl acetate, toluene, ethyl acetate-toluene mixtures, methyl ethyl ketone, or mixtures thereof with toluene, acetone, toluene-acetone mixtures, cyclohexanone, chlorotoluene, cyclopentanone, and tetrahydrofurfural, to which may be added benzene, chlorobenzene, naphthalene, nitrotoluene, nitrobenzene and ethylene dichloride. A catalyst is generally employed and may be actinic light, hydrogen peroxide, benzoyl peroxide, o,o1-dichlorobenzoyl peroxide, caproyl peroxide, caprylyl peroxide, pelargonyl peroxide, cumene hydroperoxide, tert.-butyl hydroperoxide, 1-hydroxy-cyclohexyl hydroperoxide, tert.-butyl diperphthalate, tert.-butyl perbenzoate, sodium, potassium and ammonium persulphate, and sodium perborate and percarbonate. Polymerization is preferably carried out in an inert atmosphere at temperatures of from -30 DEG  to 100 DEG  C.  The polymer solutions form strongly adherent lacquer coatings on aluminium, iron, steel, brass, copper, tin, lead and glass surfaces and are not sensitive to water.

Filed: 1928-02-13
Abstract: 311,019. B³ttner-Werke Akt.-Ges. and Zikesch, H. Feb. 13, 1928. Pulverulent - fuel burners. - In a coal dust burner, a mixture of fuel and air is admitted at the apex of a gradually diverging or stepped chamber and additional air is admitted tangentially to the chamber at a number of points at different distances along the axis of the burner so that the mixture is set in rotation and the smaller fuel particles tend to form a core in the whirling mixture, surrounded by the heavier fuel particles and an enveloping mantle of air. Fig. 1 shows a burner having a bell-shaped combustion chamber at the apex of which coal dust and air are supplied through a pipe 2 containing a helical blade 3. Secondary air is introduced tangentially from a casing 4 surrounding the combustion chamber through tangential openings 11 - - 14. The mixture is ignited by an oil or other primary burner 15 passing through the conduit 2. The oil burner 15 is preferably of sufficient heating power to maintain the operation of the burner during temporary interruption of the coal dust supply. Fig. 5 shows another burner construction in which the combustion chamber is stepped so as to allow three expansions of the fuel mixture introduced through the conduit 12 to take place. The priming burners 21, 22 are preferably arranged obliquely or tangentially so as to assist in whirling the burning mixture. Figs. 8 and 9 show a further burner construction in which three priming burners 35, 36, 37 are provided while two coal dust supply conduits 27, 28 and two compressed air feeders 29, 30 are arranged tangentially in the side wall of the chamber. Additional air is supplied through openings 54, 55 in the stepped portion of the chamber. The fuel and air openings are preferably of slit form so that the fuel and air currents are discharged in spiral bands which wind on each other. The Specification states that by the use of the burner the fuel mixture may be supplied at a velocity of over 20 metres per second, a pressure of over 300 m.m. of mercury and at a temperature from 100‹ to 150‹ C. while the secondary air may be supplied at a pressure of over 20 of mercury and at temperatures up to 450‹ C.

[Classes 7 (v) and 7 (vi)] [See also Group XXIX] A device for automatically supplying a mixture of air and gas of substantially constant ratio comprises a piston 11 controlling the air inlet 15 and provided with a metering- pin 10 controlling the gas inlet 17, the piston 11 being subjected through a passage 21 to the pressure in the mixture pipe 19, and also to the action of a spring 20. The device may be used for supplying gas and air to motorvehicle engines, either for starting from a gas supply in the garage, or for running by means of a gas stored on the vehicle. Increase in suction in the pipe 19 causes the piston 11 to rise and increase the supply of both gas and air. The pin 10 may be slightly convex at its upper part to maintain a more correct ratio of gas to air. When used for starting, the device is connected by a flexible tube 22 having quick end connections, to a flange 23 inserted in the induction pipe, and having passages 25 leading to a bore 24 which coincides with the induction pipe. When the tube 22 is disconnected, a shut-off valve prevents inlet of air to the flange 23. When used for normal running, the piston device 11 may replace the usual carburetter.

Title: Process for transforming aliphatic hydrocarbons into higher hydrocarbons
IPC: C07C2/76
Filed: 1931-02-14
Abstract: Aliphatic hydrocarbons are heated for a period less than 0,001 second to temperatures exceeding 1600 DEG  C., and the product, which contains acetylene, is then exposed for a longer period to temperatures between 450-1000 DEG  C. in apparatus constructed so that colder walls are provided opposite to the hot walls; after cooling, the benzene and oils produced are extracted in known manner. A suitable catalyst, such as aluminium oxide or aluminium oxide with 10 per cent of potassium carbonate may be used in the second stage. The process may for example be applied to the treatment of pure methane, mixtures of methane with its homologues, and other gases such as hydrogen and nitrogen may also be employed.  The gases under treatment may be heated by combustion of gas or by electricity, the gas or combustion air, or both, being regeneratively preheated if desired.  For the combustion of the heating gases it is advisable to use oxygen or gases rich in oxygen or gases rich in oxygen instead of air.  When heating by electricity, the gases may be carried past the current-conducting resistances, such as carbon plates, or the gases may be fed through tubular aggregates which are heated externally by electrical resistances.  The heat of the reaction gases may be used for generating steam, and the heat of the reaction gas from the first stage may be utilized for maintaining the temperature in the second. The relatively cold walls of the apparatus used in the second stage may be designed as sets of tubes which are filled with water or other suitable liquid, which may be boiling at atmospheric, reduced or elevated pressure.  In the example, methane is passed through a tube at 2000 DEG  C., and the product is passed through a porcelain tube heated to 600 DEG  C., and having an axially disposed copper tube filled with boiling water. The product contains chiefly aromatic hydrocarbons.
