Abstract: 484,270. Metals; alloys. WARGONS AKTIEBOLAG. Aug. 30, 1937, No. 23718. Convention date, Sept. 9, 1936. [Classes 72 and 82 (i)] [Also in Group XI] In a method of producing iron, nickel, chromium, cobalt, manganese, tungsten, molybdenum, and vanadium, or their alloys, poor in carbon and silicon from their oxides or oxide ores by reduction with silicon or a silicon alloy, these materials are reacted in a powdered state at a low temperature so as to produce a sinter in which the reduced metal is distributed in the form of fine particles to give the sinter a high electrical conductivity ; the sinter so formed is used subsequently, or if desired immediately afterwards, as an electrode in an electric furnace so as to melt therein. In the production of ferro-chromium, chrome ore and ferro-silicon, aluminium-silicon, or calciumsilicon are crushed and ground, mixed and charged into a preheater 1 and thence into a tube 2 of thin sheet-iron which is heated at 3 at 1200-1250‹ C. to effect the sintering. The tube extends into an electric furnace 4 containing a slag bath 5 of silicates mixed with oxides such as those of chromium, aluminium, and magnesium which serve to refine the product and is supplied with current at 7. As the electrode melts further portions of tube are added at 2. The sintering may take place with the tube in a horizontal position and several electrodes may be jointed by means of sheet metal shells. Alloys of iron with 14À8 per cent of silicon, 60 per cent of chromium, and 0À25 per cent of carbon and with 1À9 per cent of silicon, 64 per cent of chromium, and 0À14 per cent of carbon are referred to.

Abstract: 259,554. Jessup, A. C. Oct. 9. 1925, [Convention date]. Electrolytic furnaces. -A furnace for the refining of magnesium and other alkaline earth metals comprises a cast iron cell the base of which serves as anode connection. In the furnace there are disposed four successive molten layers, viz., a lowermost layer of the anode alloy, a layer of chlorides, the cathode layer of refined metal and an uppermost protective layer of light chlorides. The cell is provided with a refractory lining g inside which at the height of the cathode layer is mounted a cylindrical sheet c of a metal wetted by magnesium, e.g. chromium, silicon or tungsten. The sheet e is intended to prevent creeping of the upper and lower chloride layers along the walls; the sheet must not project into the electrolyte. It may be replaced by a plate or grid and may form the cathode connection. Alternatively the cathode connection may be formed by rods k of carbon, graphite, iron, or other material. The cell is provided with an air-tight cover h. The process is started by pouring in the layers successively before passing the current. According to the Specification as open to inspection under Sect. 91 (3) (a) the current may be started before adding the two uppermost layers to produce an initial deposit of magnesium on the sheet e. This subject matter does not appear in the Specification as accepted.

Abstract: 772,186. Making metal-fabric; angular bending. BAKER, Ltd., G., and DARBY, A. Nov. 18, 1955 [Aug. 20, 1954], No. 24255/54. Class 83 (4). A machine for attaching the wires 25 of a mesh or network of relatively fine wires to a stout wire, rod or strip 24 forming part of a frame carrying the mesh or network, comprises power-operated means 18 for temporarily clamping a frame wire 24 with the mesh wires 25 below it against a base 20 and against a vertical stop-plate 13 which is slotted, at 14, for the passage of the mesh wires 24 and is of substantially the same thickness as the mesh wires, a vertically movable member 26 adapted to engage the mesh wires 24 from below and bend them upwardly into a vertical position against the rear surface of the frame wire 24, and a bending member 32 adapted to be moved horizontally to engage the upwardlybent ends of the mesh wires and bend them forwardly over the frame member 24 and then to be moved downwardly to close the ends of the mesh wires tightly round the frame wire. The mesh is laid on a table 12 with the ends of the wires 25 projecting through slots 14 in the stop-plate 13. A slide 17 is then lowered by lever means operated by a cam on a shaft controlled by a pedal-operated clutch 22. A shear blade 16 on the slide 17 co-operates with an insert 15 in the table 12 to shear simultaneously the ends of two wires 25 to the correct length, while a clamp 18 on the slide 17 holds the frame wire 24 and mesh wires 25 against the base 20 inset in the table 12. A pair of the members 26 is then moved up by a cam-operated lever 28 and two of the bending members 32 are then moved forwardly by another cam and then swung downwardly about their axis to close the ends of two wires 25 on the frame wire 24. The benders then return to their normal position and the slide 17 rises. The mesh is moved transversely to bring two more mesh wires to the bending station and two more to the shearing station. More than two wires may be bent simultaneously. Specification 510,465 is referred to.

Filed: 1973-05-22
Abstract: 1374740 Cathode-ray storage and display tubes INTERNATIONAL BUSINESS MACHINES CORP 22 May 1973 [30 June 1972] 24319/73 Heading H1D A storage display tube capable of selective erasure includes a layer of ferroelectric ceramic adjacent the inner surface of the tube faceplate, with means for applying a potential across the layer, means for producing an electron beam, and a target which is responsive to the electron beam to change the polarization of a portion of the layer. In one embodiment, Fig. 1, the ferroelectric wafer 19, of lead zirconate/lead titanate ceramic, is sandwiched between a conductive layer 17 and a mosaic of conductive, reflective, aluminium elements 21, upon which is superimposed a cadmium sulphide photoconductive layer 23, a conductive coating 25, and a zinc sulphide or zinc oxide phosphor coating 27, the wafer being maintained polarized by mechanical strain produced by flexing the faceplate assembly inwardly or outwardly after manufacture. An electric field is applied across the wafer via switch 31, 33 and layers 17 and 25, and is modulated-to modulate the birefringence of the wafer-by incidence of the grid-controlled electron beam on the phosphor layer and consequent local conductivity change of the photoconductive layer. To view the image, switch 31 is earthed at terminal 37 and plane polarized light from polarizing prism 45 is reflected from the mosaic 21 and produces an intensity image on screen 49 corresponding to the birefringence modulation. To erase the image, switch 31 is moved to contact 39 to apply a field of opposite sense across the wafer, and the electron beam scans or floods the target 27, or is directed only at a portion of it, to effect complete or only local erasure, respectively. A non-stored image may be superimposed upon a stored image if the opaque reflecting mosaic 21 is replaced by a dichroic filter transmitting, say, green and reflecting blue light, where the output of phosphor layer 27 is green, and source 43 is blue. An electrical output may be derived from a stored image by scanning the phosphor layer with an unmodulated electron beam and monitoring the current flow through conductive layer 17 or 25. In an alternative embodiment (Fig. 2, not shown) which does not require the use of polarized light and which employs the optical scattering effect of local polarization in a ceramic PLZT ferroelectric, the latter is mounted in a strain-free manner, and light incident on polarized portions thereof from a mirror is reflected diffusely, part of the reflected light thereby missing the mirror and forming a corresponding image point on a display screen.

The system of an electric switch 1 of Fig. 9 comprises a forked support 77 with notched ends, Fig. 12, not shown, for a three-limbed spring 21, Fig. 13, not shown, carrying a contact 19 movable between two positions 13, 14 by a pushbutton 34 engaging the central limb 24. The switch 1 is located in a holder 122, Fig. 14, by ribs 131, 132 engaging beneath it, and held by sprung dogs 133 at its top in contact with elements 144, 146, 147 of a control circuit. The bending-die 73, Fig. 1, is forked to engage the support 77 and is mounted on a vertically reciprocable rack operated by a handle 53 when an electromagnetic clutch 42 is energized. The die 73 is returned to up position by a weighted pulley-segment 59 controlled by a liquid dashpot. The limb 24 is loaded, at the point of normal engagement with the button 34, by a pivoted, weighted arm 87 and an auxiliary weighted arm 88 which is lifted from an extension 107 of the arm 87 when a hook 82 on the die-holder 38 pivots a lever 111 to engage a pin 112. A preloading switch, Fig. 2, not shown, is opened by an extension of the handle 53 when the holder 38 is near its lowest position. A suitable A.C. or D.C. supply 149, Fig. 17a, is provided for the clutch 42 and controls the release of the bending-die 73 through the contacts of the switch 21a being adjusted. The switch 1 with its cover removed is placed in the holder 122, and for double-throw and normallyopen switches the clutch 42 is fed through the preloading switch 148 and downward movement of the handle applies a load due to both arms 87 and 88 to snap the switch to closed position. As the handle is lowered the switch 148 opens and the clutch is fed through the switch being adjusted. Further handle movement lifts the arm 88 so that the spring 21 is preselectively loaded by the arm 87 alone. The die 73 then deforms the support 77 until the switch snaps back to normal, de-energizing the clutch 42 to raise the die 73 and remove the load. In a modification a circuit is provided for adjusting normally closed switches. In a further modification a single circuit with a change-over switch is provided for the three types of switch.

Title: Improvements in or relating to processes for the treatment of hydrocarbon oils
IPC: C10G17/06
Filed: 1947-09-05
Abstract: Halogenated hydrocarbons are obtained from hydrocarbon oils, such as those produced from petroleum, coal or shale, by first treating the oils with aqueous sulphuric acid so that only the more highly unsaturated constituents and the asphaltic materials are removed, then treating the residual oils with a halogen such as chlorine so that the remaining unsaturated constituents are halogenated while the saturated constituents are left unchanged, and finally separating the halogenated materials from the saturated constituents by fractional distillation.  The p  halogenated hydrocarbons may be converted to sulphonated or sulphated hydrocarbons by treatment with sulphonating agents such as oleum, chlor-sulphonic acid, sulphur trioxide or sulphuric acid.  In an example, shale oil is repeatedly washed with 60-80 per cent sulphuric acid and all sludge is removed.  After washing the residual oil with weak caustic soda and drying, gaseous chlorine is passed through the dried oil for 20-60 minutes, whereupon the portion of the oil which has not reacted with the chlorine is distilled off.  The chlorinated oil may be sulphonated with concentrated sulphuric acid and then neutralized with caustic soda.ALSO:Hydrocarbon oils, including those produced from petroleum, coal or shale, are refined by first treating the oils with aqueous sulphuric acid so that only the more highly unsaturated constituents and the asphaltic materials are removed, then treating the residual oils with a halogen such as chlorine so that the remaining unsaturated constituents are halogenated while the saturated constituents are left unchanged, and finally separating the halogenated materials from the saturated constituents by fractional distillation.
