Filed: 1917-02-23
Abstract: 113,331. Munster, Simms, & Co., and Eves, C. W. Feb. 23, 1917. Concentric or jacketed straight-tube apparatus. -Surface apparatus of general application but designed particularly to heat air in internal-combustion engines comprises a pipe around which is wound a spiral of wire between headers. The wire coils form a support for a cover of thin metal or non-metallic material either in the form of sheets or of bands which are wound around the coils and secured to the headers. The fluid to be heated or cooled enters through holes in a header b<1>, Fig. 9. circulates among the coils A inside the casing B, Fig. 6, and escapes through a lateral outlet b which is shown on a separate sheet-metal cover C, Fig. 9. The wire spirals are preferably of half-round section to increase metallic contact with the pipe.

Title: Method of producing alkali phosphates
IPC: C01B25/30
Filed: 1930-01-25
Abstract: 335,492. Metallges. Akt.-Ges. Oct. 17, 1929, [Convention date]. Alkali phosphates; iron, copper, and manganese sulphides. - Phosphates of alkalis, including sodium and potassium, and especially trialkali phosphates, are produced by fusing, for instance, at 1150‹-1250‹ C., a mixture, of alkali sulphate and metal-phosphorus alloy, for example, ferrophosphorus, phosphorus-copper or phosphorus manganese, preferably in the condition of powder or small lumps, in an electric resistance furnace. Two-phase or polyphase alternating currents may be employed. The process is preferably carried out by adding continuously small portions of powdered raw materials to the fused mass, whereby the latter is protected from atmospheric oxidation by a layer of sintered material, covered with a layer of unaltered mixture. The reaction product, either in a fused state, or crushed or atomized, is leached with water and iron, manganese or copper sulphide is obtained as a byproduct.

Abstract: 494,803. Thermionic valves ; detecting and generating circuits. STANDARD TELEPHONES & CABLES, Ltd. Jan. 28, 1938, No. 2809. Convention date, March 15, 1937. [Classes 39 (i) and 40 (v)] The cathode of a thermionic valve for generating or detecting high-frequency waves is so constructed that when a stationary wave is set up in the cathode of a period equal to that of the wave dealt with the emission is high at the potential loops and low at the nodes. For this purpose the cathode-filament is thinned at the points where the nodes occur, e.g. by electrolysis, or heat-dissipating fins may be arranged at the loops. Fig. 6 shows a circuit utilizing such a valve. A voltage of the required frequency is supplied from a source E to an electrode 2 surrounding a cathode 1 constructed as described. To the cathode 1 and an outer electrode 3 is connected a resonant circuit comprising two parallel conductors 53, 57 and a condenser C, the electrode 3 being supplied from a potential node A in this circuit. The condenser C may be placed near the node A, as shown, or near the cathode 1. A condenser C1 forms with the cathode leads 51 a second resonant circuit.

Title: Improvements in or relating to the production of paper pulp and paper products
IPC: D21J1/00
Filed: 1929-01-28
Abstract: 324,527. Serebriany, M. M. Jan. 28, 1929. No Patent granted (Sealing fee not paid). Pulp, preparation of.-In the production of paper pulp, pasteboard, cardboard, paper and other pulp products, the fibrous materials of vegetable origin such as wood, wood bark, sawdust, moss, straw, reeds and cork, with the addition if desired of animal substances such as rags, leather waste, and the like are ground fine, preferably after being previously dried to a moisture content of about 4-6 per cent. They are then sorted to separate unground matter and swelled and stirred in cold water, or in hot water at 60‹-80‹ C., or in a mixture of equal quantities of turpentine and either benzine or petroleum. The mass may be rendered soft and resilient by the addition of about 2-4 per cent of caoutchouc or leather dust. Fillers such as asbestos, alumina, magnesia, chalk, leather dust, glass dust, meal, pumice stone, mica, or the like may be added to the mass, and the mass supplied to paper or pasteboard machines, or to presses to form plastic articles. Where turpentine, benzine, or petroleum are used for swelling, the mass may be worked up into paper or the like by rolling. An ordinary fibrous mass of wood or rags may be added to the mass before swelling. Where wood bark is used, a portion is treated with common salt solution before grinding, then ground up in a moist state, then treated in edge mills or the like. An equal mass of dry ground bark is then added with, if desired, ordinary fibrous material of wood, flax, hemp, or the like, and the mixture worked up into a very strong and elastic pasteboard, paper, or the like. Another method of treating wood bark consists of steaming in boilers at a pressure of 2-4 atmospheres before grinding.

Title: Improved manufacture of nitrates
IPC: C01D9/06
Filed: 1928-01-31
Abstract: 308,028. Bronn, J. I., Fischer, G., and Concordia-Bergbau Akt.-Ges. Jan. 31, 1928. Hydrochloric acid. -Nitrates, particularly of sodium and potassium, are obtained by treating the corresponding chlorides with nitric acid mainly in vapour state, or with nitrogen oxides admixed or not with air or oxygen, in the presence of copious quantities of steam, for instance 10-15 times the quantity of nitric acid vapours. For example, solid potassium chloride may be fed continuously or intermittently to a tower 1, having a false bottom 2, to which vapours of nitric acid are admitted by a pipe 4 and steam superheated to say 120-130‹ C. by a pipe 5; or dilute nitric acid may be introduced to the middle of the tower, or the steam and nitric acid be introduced together. A solution of substantially pure potassium nitrate collects at 6 and may be discharged through the valved syphon 7. Acid vapours escaping by the pipe 9 may be freed from hydrochloric acid in a chamber 10, the resultant steam being re-used after being reheated at 130‹ C. Alternatively, a solution of potassium chloride may be employed, as by filling the tower with rings or pieces of ceramic material over which the solution trickles, but the nitric vapours should then be introduced into the solution 6 to free it from chloride. In treating a solution of common salt, eight parts of steam to one of nitric acid may be employed, and the tower may then be filled with pieces or briquettes of salt. The acid chloridebearing liquid obtained by treating a solution of potassium chloride with nitric acid in the usual manner and separating the crystalline potassium nitrate precipitated, may be used in the process, if desired with the addition of potassium chloride solution, the aid liquid being, however, admitted to the middle of the tower. When crude potassium salts are treated by the methods described the solution 6, containing nitrates of all the metals present, such as potassium, sodium, calcium and magnesium, may be treated with fresh crude salt to increase the yield of potassium nitrate and reconvert the other nitrates to chlorides; or the conditions of treatment may be so varied that potassium, nitrate is preferentially obtained. Should the final product contain free acid, this is neutralized by means of lime or alkalies or their carbonates.
