Patent GB-719835-A (GB)
Title: Improvements in or relating to metal powders
IPC: B22F9/18
Filed: 1952-07-03
Abstract: Alkali metal addition products of ethers of polyhydric alcohols are formed by mixing the ethers with alkali metal in a subdivided state, preferably dispersed in an inert medium such as liquid aromatic or aliphatic hydrocarbon.  The alkali metal is fused and vigorously agitated with the inert medium while maintained at a temperature above the melting-point of the metal.  The dispersion, which may contain 20-50 per cent of alkali metal, reacts with the ether at room temperature to give an addition product insoluble in the reaction medium.  An ether to metal ratio of 4 : 1 to 10 : 1 is preferred. Suitable ethers are ethylene glycol dimethyl ether, tetraethylene glycol dimethyl ether, triethylene glycol methyl ethyl ether, ethylene glycol methyl ethyl ether and ethylene glycol diethyl ether.ALSO:Metal powders are prepared by reduction of metal compounds with an alkali metal addition product of an ether of a polyhydric alcohol such as ethylene glycol dimethyl ether.  The preferred metal compounds used are the halides and the use of halides of Fe, Ni, Co, Cr, Mn, Mo, Zn, Cd, Sn and Ag is specifically referred to. Other compounds such as sulphates, nitrates, carbonates, acetates and formates may be reduced.  Reference is also made to the production of alloy powders by reduction of mixed compounds e.g. the mixed chlorides of Fe and Ni, Fe and Co or Fe and Cr.  The reaction may be carried out by initially forming the alkali metal-ether and then mixing it with the metal compound, preferably using an excess of the alkali metal.  Alternatively the metal compound and ether may be mixed and the alkali metal then added as a dispersion in an inert medium such as liquid aromatic or straight chain hydrocarbons.

Title: Process for the manufacture of liquid products from coal or carbonaceous materials by heating under pressure in the presence of hydrogen or gases or vapours containing hydrogen
IPC: C10G1/08
Filed: 1929-05-31
Abstract: 314,859. Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij. July 3, 1928, [Convention date]. Catalytic materials.-A catalyst for use in the destructive hydrogenation of coal and other carbonaceous materials is made by treating Luxmass (alkaline iron oxide, obtained in the wet purification of bauxite) with water. It may be washed one or more times and at normal or elevated temperatures. 40g. of Luxmass containing 36.6 g. of dry substance was repeatedly treated with ¢ l. of water on a steam bath. After setting the mass was filtered and dried at 120‹ C., 13.4 per cent of the original dry substance having been removed. When this sample was used in the destructive hydrogenation of brown coal, the residue of unchanged coal was 34 per cent: under the same conditions, using untreated Luxmass, the residue was 13.4 per cent.

Title: Improvements relating to telephone instruments
IPC: H04R7/20
Filed: 1929-05-31
Abstract: 332,689. Mullard Radio Valve Co., Ltd., and Hayes, C. F. M. May 31, 1929. Addition to 308,448. Diaphragms.-Relates to a diaphragm, particularlv for use in hornless loud-speakers, which is supported with its circumference free in air, as described in the parent Specification, by means of a relatively non-extensible tensioned cord &c. engaging the diaphragm at a number of points spaced around its circumference in such a. way that the cord can slide with respect to the diaphragm. According to the invention, the cord &c. does not impose a radial tension on the diaphragm at all its points of attachment. It may impose a compression at all points or a compression at some points and a radial tension at other points, whilst at some points it may merely act as a support without exerting any appreciable tension or compression. In the construction shown in Fig. 1, the cord e tensioned by spring l passes over hooks m constructed as shown in Fig. 3 and secured to the periphery of the conical diaphragm b, the cord passing beneath all the pegs f on the casing a so as to exert a compression at all points of attachment. In the modification, Fig. 4, the hooks m are provided at the top and bottom of the diaphragm b and the cord e passes inside the pegs f<1> between and immediately adjacent these hooks so as to exert a compression on the top and bottom of the diaphragm. The cord, however, passes outside all the other pegs f<2> and at the sides of the diaphragm passes between resilient blades o, Fig. 6, which are riveted to the edge of the diaphragm and merely retain the cord in a radial direction by friction without exerting any tension or compression on the diaphragm. In a further modification, Fig. 8, the cord passes around all the pegs f and at the top and bottom of the diaphragm exerts a radial tension thereon by engaging hooks d, Fig. 10, of a construction similar to those described in the parent Specification, blades o being provided at the sides of the diaphragm as in Fig. 4. A further modification, Fig. 11 (not shown), employs hooks d at the top of the diaphragm, hooks m at the bottom thereof and blades o at the sides.

Title: Improvements in the Manufacture and Production of Leather.
Inventor: WILLIAM CHARLES BLATZ
IPC: C14C3/04
Filed: 1917-11-16
Abstract: 111,304. Blatz, W. C. Nov. 16. 1916, [Convention date]. Void [Published under Sect. 91 of the Act] Proofing.-White leather is made by incorporating with the skins or hides an insoluble white salt of one of the alkaline earth metals during or subsequent to a chrome or like tanning or tawing. Barium sulphate is preferred, and the process may consist in impregnating the skin alternately with a soluble salt, e.g. sodium sulphate, and barium chloride, by drumming the skins in solutions of these salts, thus effecting the precipitation of barium sulphate within and upon the body of the skin. Skins thus treated are more impervious to moisture, and are improved by glazing.

Abstract: 566,568. Knitting. WOODCOCK & SONS, Ltd., G., and WOODCOCK, H. E. Jan. 1, 1943, No. 17079/42. [Class 74 (ii)] In knitting the leg, heel tabs and foot of a stocking or like blank upon the same straightbar machine without a running-on operation, so that the inner edges of the heel tabs are united to the foot bottom during the knitting process, knitting is temporarily suspended on a central group b, b of instep needles, the heel tabs ht are knitted on needles outside the central group of inactive needles, and the width of the group of inactive needles is progressively increased. After the desired heel fabric has been produced, knitting of the instep and foot bottom is effected on the increased group of needles. The heel tabs may be shaped by excluding the outer selvedges from the transfer operations during part of the knitting of the tabs. Auxiliary pressers 17a, 17b are provided for pressing the needles knitting the heel tabs and means are provided for moving these pressers outwardly in conformity with the transfer operations to effect the progressive increase in the number of temporarily inactive needles. Two transfer points 111, additional to the usual transfer points 11, are provided to transfer fabric to the needles that are progressively rendered inactive. The auxiliary points transfix the fabric at the plain side of the needles and position it for reception by the needles rendered inactive. The points 111 are mounted for dipping and swinging movement independently of the transfer points 11. To enable the heel tabs to be shaped, peaking blades 14 are provided for masking the action of selected transfer points 11.
