Abstract: 152,340. Rumpler-Werke Ges. Nov. 5,1917, [Convention date]. No Patent granted (Sealing fee not paid). Planes, connecting together and to machine; framework.-A biplane or multiplane wing has two superposed planes rigidly connected by a strut having extensions connected to the planes and extending in one direction only. Fig. 1 shows a biplane wing braced by a single strut 25, having rigid extensions 30, 31, and by two cables 27, 28. The strut 25 is formed from a streamline section tube laterally flattened at its ends where it is welded to the arms 30, 31 which are formed in halves from sheet metal blanks welded together. The ends of the struts are closed by plates carrying bushes to receive holding screws. The cables 27, 28 may have streamline casings. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter which does not appear in the Specification as accepted. The adjacent planes of a biplane or multiplane are connected together by a single row of struts 4 and bracing 5, as shown in Fig. 2 (Cancelled), the bracing being completed bv struts 7 which are integral with the struts 4 or detachably hinged thereto to enable the planes to be folded against the row of struts 4. The angle of incidence of each plane may be adjusted by providing a number of holes along the struts 4 to take the ends of the struts 7. Or the struts 7 may be connected to the ends of the struts 4, and may be made adjustable in length, as shown in Fig. 6 (Cancelled). The folded planes may be turned back parallel To the fuselage. The struts 4 may be connected along the line of the centres of pressure of the planes and parallel to the direction of the lifting forces as shown in Fig. 7 (Cancelled), which also shows another arrangement of the struts 7. This subject-matter does not appear in the Specification as accepted.

Filed: 1956-07-09
Abstract: A method of flame spraying in which a solid coating material in the form of a rod or powder is conducted into a flame and projected in heated and particulate form together with the burning gases against an object to be coated, is characterized in that the coating material is introduced into the point of convergence of a number of separate flame jets which are discharged from their respective burner passages at a velocity in excess of 2000 feet per second, and which merge externally of said passages to form substantially a single resultant jet.  Materials which may be sprayed include metals, alloys, metallic compounds, plastics, ceramics and minerals.  The materials coated include graphite, wood, paper, glass, sapphire and many metals.  A flame spray gun (see Group XXIX) for effecting the method includes a body 11 with a bore 12 for the spray material, and three symmetrically spaced combustion chambers 14 with outlets 14b.

Title: Purification of zirconium tetra halides
IPC: C01G25/04
Filed: 1958-07-03
Abstract: Zirconium tetrahalides are purified by heating a molten mixture of impure zirconium tetrahalide and at least one alkali-metal halide to vaporize the zirconium tetrahalide, there being present in the mixture a minor amount of a material or materials selected from the group iron, zirconium, zirconium di- and trihalides, and zirconium halide-alkali metal halide complexes.  The process may be effected in a continuous manner by adding impure zirconium tetrahalide to the molten mixture at substantially the same rate that pure zirconium tetrahalide vaporizes.  The molten mixture preferably comprises 50-90% wt. zirconium tetrahalide and 10-50% wt. alkali metal halide. The zirconium halide-alkalimetal halide complexes may for example be prepared by passing zirconium tetrachloride and sodium into a bed of sodium chloride at a temperature above the melting point of sodium but below the melting point of sodium chloride.  The bed is agitated either mechanically or by fluidisation.  The reaction is carried out in an inert gas atmosphere.

Title: Process for the working up of crude cellulose ester solutions
IPC: C08B3/28
Filed: 1930-07-16
Abstract: Crude solutions of fatty acid esters of cellulose obtained by the acylation of cellulose in the presence of solvents insoluble in water, for example chlorinated hydrocarbons, are worked up by the addition of limited quantities of water, if desired after neutralization of the catalysts, followed by distillation whereby the water-insoluble solvents are removed in azeotropic mixture with water.  The small quantity of free fatty acid formed in the course of the reaction is sufficient to ensure that the residue from the distillation consists of a clear solution of the cellulose ester, which may then be precipitated in the normal manner.  The quantity of water added in the preliminary precipitation should be so chosen that there remains after distillation an approximately 50 per cent solution of fatty acid. In examples, (1) an acetylation mixture containing ethylene chloride as the principal solvent is precipitated with a small amount of water and distilled at about 85 DEG  C., and the cellulose acetate is separated from the resulting solution in 50-55 per cent acetic acid in the usual manner; (2) a reaction mixture comprising cellulose acetobutyrate in solution in methylene chloride, glacial acetic acid, butyric acid, and water is treated as in the first example, the distillation temperature in this case being about 40 DEG  C.  Specification 337,366, [Class 2 (ii), Cellulose &c.], is referred to.

Title: Improvements in or relating to manufacture of refractory articles
Inventor: WILLIAMS ALBERT ETHERIDGE
IPC: C04B35/622
Filed: 1949-08-19
Abstract: A process for the production of refractory articles of magnesia comprises the steps of forming ground pure magnesium oxide into a slip by admixture with a lower aliphatic alcohol in quantity sufficient to make a flowing suspension, casting the slip in a porous mould and subsequently firing the dried cast at a sintering temperature.  The magnesium oxide should be at least 98 per cent and preferably 99 per cent pure, and before being dry ground is preferably calcined at about 1500 DEG  C.  For most satisfactory slip formation the magnesia should be ground so that 60 per cent of the particles have a size less than 5 microns.  The quantity of lower aliphatic alcohol should be sufficient to give a flowing suspension when mixed with the ground magnesia, forming a slip containing 85 per cent to 94 per cent magnesia by weight. The preferred alcohol is ethyl alcohol and it should not contain more than 1 per cent water. The cast may be removed from the mould after partial drying and before sintering is preferably pre-fired.  The pre-firing may be done in an electric muffle furnace, the temperature being at first raised very slowly and then brought up to the prefiring temperature of 1000 DEG C to 1200 DEG C. The pre-fired article is allowed to cool in the furnace.  The sintering may be done in a gas fired kiln or in a graphite tube furnace, at 1800 DEG C to 2000 DEG C.  The Specification gives a detailed example of the preparation of magnesia crucibles.ALSO:A process for the production of refractory articles of magnesia comprises the steps of forming ground pure magnesium oxide into a slip by admixture with a lower aliphatic alcohol in quantity sufficient to make a flowing suspension, casting the slip in a porous mould and subsequently firing the dried cast at a sintering temperature.

Title: Dyestuff intermediates of the anthraquinone series and their production
IPC: C09B1/00
Filed: 1933-08-01
Abstract: A 1-halogen-2-aminoanthraquinone which may contain further nuclear halogen atoms is reacted with an alkali metal selenide, preferably in alcoholic medium, and if desired, the resulting selenolate is either converted to the free selenol by acid treatment or oxidized by aeration or treatment with mild oxidizing agents such as ferricyanide, perborate or m-nitrobenzenesulphonic acid.  The alkali metal selenide may be produced in situ by means of selenium and an alkaline reducing agent in alcoholic suspension; reference is made to the use of selenium or selenium dioxide in conjunction with sodium, aluminium or zinc in caustic soda or alkaline hydrosulphite.  In examples: (1) 1-chloro-2-aminoanthraquinone is treated with sodium selenide in aqueous alcoholic solution, or with selenium and sodium in alcohol, or with selenium and aluminium in alkali-alcohol; the selenolate may be converted to the selenol by acidification or converted to the diselenide by reaction with mild oxidizing agents such as air or ferricyanide; (2) 1,3-dichloro-2-aminoanthraquinone is reacted with sodium and selenium in alcohol containing sodium formate, or with aluminium and selenium in alkali alcohol; (3) 1,3-dibromo-2-aminoanthraquinone is reacted with sodium and selenium in alcohol.  Only the a -halogen atom is replaced by selenium in the latter two cases.  The products are of use in the process described in Specification 423,447.
