Title: Process for producing grain stabilized metals and alloys
Inventor: STREICHER JOHANN SIMON
IPC: C22C5/00
Filed: 1953-03-27
Abstract: Grain stabilised metals consisting of one or more of Pt, Ir, Os, Pd, Rh, Ru, Au, with or without the addition of one or more of W, Mo, U, Cr, Mn, Fe, Co, Ni, Be, Re, Ag and Cu are produced by melting the first listed metal or metals in a non-oxidising atmosphere and in the absence of a fluxing agent, incorporating into the fused metal at least one element capable of forming an oxidation at the fusion temperature of said metal, a non-volatile chemically stable oxide, evenly distributing said element, exposing the melt to an oxidising atmosphere to convert the metal to an oxide which forms a colloidal dispersion in the melt of between 0,02 and 2,5 gram equivalents of the oxide per litre. The elements comprise Be, Si, Al, Ti, Mg, Sc, Cr, Nb, Ca, Zr, Ni, Fe, Co, Y, La, Ce, Hf, Nd and other rare earth elements, Th, U, Ta, Ba, and W.  If the base metal addition metals listed above are to be added to the alloy then this is done after the oxidation step.  Pre-alloys may be used to add the oxides and in this case the elements form from 0,1-25 per cent by weight of the metal The pre-alloy may be made by reacting powdered constituents or by wrapping the elements in metal foil.  The following alloy is disclosed (inter alia): .Pt.10-77.per cent .Pd.12-89.per cent .Ru.1-11.per cent  Heat-treatment.  The ingots of metal produced are hot-or-cold-worked in a conventional manner, a soaking anneal of 500 DEG -1100 DEG C. is stated to give the best results, and these temperatures are also suitable for "between anneals."  Several examples of treatments are described.  If catalytic properties are needed in the finished article reductions of area above 75 per cent are used.  The following articles are specified: catalytic gauze, electrical contacts, spinnerets and laboratory ware.  Pickling. Platinum-rhodium wire is pickled in a mixture of dilute aqua regia and ammonium chloride.

IPC: G01F1/50
Filed: 1952-04-03
Abstract: 717,060. Indicating-apparatus; pressure gauges. LANDIS & GYR AKT.-GES. April 3, 1952 [April 6, 1951], No. 8559/52. Classes 106 (2) and 106 (4). [Also in Groups XXIX and XXXVIII] In a flow meter, the ratio between the two effective arms of a lever, arranged in the transmission from a root extraction cam to an indicator member, is varied in accordance with the condition of the medium passing through the meter, by means producing substantially no retarding effect on normal movement of an instrument for measuring the condition. As shown in Fig; 1, the transmission mechanism of : a flow meter comprises a root-extraction cam 9 acting on a rod 10 connected to pointer 11 through linkwork including a lever 8 controlled by a pivoted arm 36, the transmission ratio of the lever being varied by moving a fulcrum rod 30, engaging, an arcuate,slot 38, about a shaft 28. The.rod 30 is normally at the centre of the lever, and is arranged to follow the movements of a shaft 6 which is responsive to deviations from normal in one or more conditions of the medium where flow is being measured, and, as shown, carries a pointer 7 which is moved by an adjustable linkwork 3, 4, 5 so as to indicate the difference α-# between ,the deviations from normal in temperature and pressure measured by instruments having pointers 1 and 2. The shaft 6 also carries a sector 17 and pin 16 which are periodically clamped by toggle mechanism 19, controlled by a cam 21 on a constantly driven shaft 31, while a further cam 27 allows scissor members 24, 25 to close and cause the rod 30 to move to a position corresponding to that of the pin; an elastic coupling 34 permits free movement of the pointer 7 during the clamping periods. In a modification, the pin 16 carries a member with a curved surface which co-acts with teeth on the members 24, 25; Fig. 4 shows another arrangement in which the rod 30 operates a straight line linkwork carrying a rod 45 which engages a straight slot in the lever 8 and is engaged by a flexible band 47 (replacing the arm 36, Fig. 1) held taut by a spring 49. In further modifications, the shaft 6 is connected to the rod 30 through an electric follow-up device (see Group XXXVII) or a pneumatic transmission (see Group XXIX). As shown in Fig. 9, temperature and pressure measuring instruments 65, 66 control separate plates 67, 68 adjacent outlet nozzles of pipes 71, 72 respectively. The pressures in these pipes act on diaphragms 74, 75 interconnected by a rod 76, so that this rod and rods 77, 30 are moved in accordance 'with the difference between the two pressures which corres-; ponds to α-# above.

Title: Process of pelletizing
IPC: C22B1/24
Filed: 1953-03-30
Abstract: A process of indurating pellets of mineral fines, such as iron ore fines or magnetite concentrates comprising passing the pellets downwardly in the form of a column through a shaft type furnace in which they are subjected to a counter current of oxidizing gas, is characterized in that the oxidizing gas is introduced to pass upwardly through an indurating zone in the column at an elevated temperature below that required by the pellets for induration and in that the incoming pellets contain an exothermically oxidizable component in quantity sufficient to ensure that by the combined action of the heated oxidizing gas and the said component, the pellets will attain an indurating temperature, the oxidizing gas being introduced at a temperature, above the ignition temperature of the said component, so regulated that at least partial fusion of the interiors of the pellets takes place, while any substantial fusion of the exteriors is prevented by the cooling action of the gas sweeping over the surfaces of the pellets.  A substantial portion of the gas stream passing through the lower part of the column for cooling the indurated pellets may be diverted to a combustion chamber and heated therein before passing it back into the column to the indurating zone.

Title: Improvements in or relating to the production of rubber thread
IPC: B29D99/00
Filed: 1936-03-24
Abstract: Substantially flat rubber thread is produced by streaming latex on to a coagulant through an orifice of any cross-sectional shape at the end of a capillary tube and down the surface of the end of the tube, the tube being positioned at such a height above the normal surface of the coagulant that while at least a portion of the end-surface down which the latex flows is wetted by the coagulant the coagulant does not surround the orifice.  However, rubber thread having substantially the same cross-section as the cross-section of the orifice may be produced if the capillary tube is positioned slightly nearer the normal surface of the coagulant so that the latex as it leaves the orifice is completely wetted by the coagulant.  The flat rubber thread may be converted into tubes by folding it over, into solid thread of round cross-section by twisting it, and into thread of rectangular or square cross-section by bonding together a number of threads.  The "coagulant" may be such that it brings about solidification of the latex by coagulation, gelling or dehydration and coagulation. Latex mixings prepared according to Specifications 290,313, [Class 70], and 307,315, [Class 32], may be used. Specifications 214,615 and 311,844, [both in Class 70], also are referred to.

Abstract: 654,984. Electric condensers. MICAFIL AKT.-GES. March 25, 1948, No. 8795. Convention date, March 26, 1947. [Class 37] In an electrical condenser of the type consisting of metallic layers B with oil-impregnated layers D inserted between, the whole being wound into a roll and pressed flat, glow phenomena at the edges are prevented by additional insulating inserts R. For the purpose of strengthening the marginal regions of such a condenser at least one intermediate layer of insulating material R lies adjacent and on one side of the full width insulating material packets between the metallic layers in both marginal regions, whereby of two neighbouring metallic layers at least one of the edges ending in the dielectric is covered on not more than one side by an intermediate layer. The additional metallic layers need not be present as separate metal sheets but may be in the form of a metallized layer applied by spraying, pressing or other suitable method. In a modified form where the completed wound condenser is not pressed flat the metallic layers B1 are in the form shown having an insulating material between individual metal sheets, this arrangement provides space for the extra inserts R when the condenser is wound without pressing flat. Specifications 642,267, 654,982 and 654,983 are referred to.
