Title: Process for separation and recovery of hard constituents from sintered hard metals
IPC: C22C3/00
Filed: 1944-10-04
Abstract: A process of recovering hard metal carbides from scrap material comprising hard metal carbides and an auxiliary metal, generally cobalt or nickel, in which the coarsely crushed scrap material is fused with zinc to form an alloy of zinc and the auxiliary metal, and the alloy is removed by dissolving in dilute acid, the solid residue being washed to leave the hard carbide particles. Sufficient zinc should be used to form, with the auxiliary metal, an alloy containing not more than 10 per cent. of cobalt or nickel.  Preferably dilute sulphuric acid is used as the solvent, a suitable concentration being 20 per cent. of acid to 80 per cent. of water by weight.  The recovery of tungsten carbide from a composition consisting of tungsten carbide and 12 per cent. cobalt is referred to.ALSO:A process of recovering hard metal carbides from scrap material comprising hard metal carbides and an auxiliary metal, generally cobalt or nickel, in which process coarsely crushed scrap material is fused with zinc to form an alloy of zinc and the auxiliary metal, and the alloy is removed by dissolving in dilute acid, the solid residue being washed to leave the hard carbide particles.

Filed: 1924-08-12
Abstract: 241,652. Stoney, G. G., and Boswall, R. O. Aug. 12, 1924. Testing and measuring viscosity of liquids.- The fluid is passed through a tube and an orifice in series and the pressures of the fluid measured at suitable points. The casting a is formed with top and bottom wells b, c connected by a tube d. The liquid to be measured is supplied under pressure through a pipe e and stop cock f to the well b from which it flows through the tube d to the well c and from there through a suitably shaped orifice h to a receptacle. Pressure gauges i, j serve to measure the pressure in the wells and a pocket g for a thermometer enables the temperature to be measured. From pressures measured as above, the viscosity can be readily found by calculation, or from a standardized curve; an empirical relation found to exist between factors which apply to the flow of liquids through an orifice being combined with known expressions for the discharge through tubes and orifices.

Abstract: 983,651. Grounded aircrew trainers. DALTO ELECTRONICS CORPORATION. May 22, 1962, No. 19572/62. Heading B7W. [Also in Division H4] A film transparency 37<SP>1</SP>, Fig. 7, which represents a rectilinear plan view of a surface (i.e. it represents an image of the surface viewed normally) is scanned by a cathode-ray tube flying-spot scanner 34<SP>1</SP> in a non-uniform raster as illustrated in Fig. 1 to produce signals in a photo-electric cell 38<SP>1</SP> which are applied to modulate a cathode-ray display tube 39<SP>1</SP> which is scanned with a normal raster in synchronism with the scanning of tube 34<SP>1</SP>, the arrangement being such that the reproduction of the view is distorted as shown in Fig. 2 so as to simulate the effect of viewing the plan in perspective (i.e. tube 39<SP>1</SP> produces an image of the view viewed obliquely). The raster for tube 34<SP>1</SP>, which is produced under the control of circuit 41<SP>1</SP>, is characterized by a trapezoidal shape in which both the line length and line spacing gradually increase. A circuit (of conventional form based on a chain of biased diodes) is described with reference to Fig. 5 (not shown) for producing a suitable scanning waveform to introduce the gradual increase in raster line spacing. The invention is applied to a grounded aircrew trainer in which transparency 37<SP>1</SP> is a representation of an airfield. An optical system 48 comprising a cylinder of glass having one end normal to its axis and the other at 45 degrees thereto is disposed along the optical axis from tube 341 and is controlled for rotation about its axis to simulate the flight motion of yaw. The transparency 37<SP>1</SP> is moved in directions E and G to simulate lateral and longitudinal flight movements relative to the airfield. To simulate flight motion of roll display tube 39<SP>1</SP> is viewed by a television camera 52 connected to a further display tube 54 and the camera is controlled for rotation about its optical axis. To simulate flight motion of pitch a control unit 53 is connected to provide displacement of the raster reproduced by tube 39<SP>1</SP>. To simulate change in altitude circuit 41<SP>1</SP> is controlled to introduce changes in line length and spacing in the raster scanned on tube 34<SP>1</SP> so as to produce the appropriate change in perspective in the reproduced view on tube 39<SP>1</SP>.

Title: Improvements in asymmetrically conducting electrical devices and methods of making them

Filed: 1944-10-11
Abstract: 594,959. Detectors. WESTERN ELECTRIC CO., Inc. Oct. 11, 1944, No. 19628. Convention date, July 28, 1943. [Class 40 (v)] A method of making elements of electrical rectifiers comprises causing a silicon body to react with a lead compound to form a crust on the surface of the silicon, freeing some elemental lead which enters into solution with the silicon and removing the crust to expose a surface of the silicon with which the lead is alloyed. In Figs. 1, 3, a layer of silicon 2 is deposited on a strip of tantalum 1 by heating the strip in an atmosphere of silicon tetrachloride and hydrogen, further heat treatment causing this layer to melt, whereupon it is allowed to cool and crystallize. The strip is mounted on stands 3, 4 in an exhaustion chamber 7 in which is also mounted a metallic trough 6 containing lead oxide, which, after the exhaustion of the chamber, is heated by source 10 through circuit 14. The heated oxide evaporates and forms a layer 15 on top of the silicon layer, and on heating the strip with a current through leads 16, 17, these layers 15, 2 react to form a crust under which is formed a layer of lead and silicon alloy. The crust is then removed, leaving the layer of said alloy and the strip is then ready for utilization. In a crystal rectifier (Fig. 6) a portion of the strip is welded by its tantalum strip to a metal stud 19 threaded into a ceramic cylinder 21, into the other end of which is threaded a hollow stud 22. This stud receives a cylindrical metal contact holder 24, which is adjusted until the tip end of a tungsten wire 25 contacts with the alloy surface of 18, and then locked in this position by setscrews 26.
