Filed: 1940-09-02
Abstract: 543,711. Electrostatic separators. MASSE, T. J. Sept. 2, 1940, Nos. 13760, 13761, 13762 and 13763. Convention dates, Sept. 30, 1939, Nov. 24, 1939, Feb. 8, 1940 and March 26, 1940. [Class 72] In the electro-static separation of fabric fragments from rubber fragments in a mixture of the same, the mixture is passed into an electrostatic field formed by a repelling electrode and a collector electrode charged to such an extent that the fabric fragments are attracted, and adhere, to the latter electrode, the fragments being subsequently removed therefrom. The fragments on the repelling electrode are agitated and may be screened before arriving in the electro-static field. The humidity of the air in the vicinity of the collector electrode is controlled so as to maintain its surface in a dry condition. The mixture of free fabric segments, free rubber segments and rubber fragments containing embedded fabric fragments is fed from a hopper 4 on to spreader boards 5 forming part of a frame 6 mounted on flexible legs 7 which enable it to vibrate under the influence of out-of-balance weights 8 which may be rotated by a motor 9. The fragments pass on to a screen 10 mounted on the framing 6, free rubber fragments passing through the screen into a shoot 11. The rest of the material passes over a repelling electrode 13 and under collecting electrodes 12 comprising metal cores 19 enwrapped by sleeves 20 of di-electric material and an outer covering of felt 21 or other material having a minutely tentacled surface. The electrode 13 is earthed and the collectors 12 are charged from a rectifier 22 by brushes 23. The fabric segments are attracted to the collectors 12 are removed through slotted headers 15 and conduits 16 by a fan 14. To improve the efficiency of the apparatus, field plates 24 connected to the electrode 13 are provided near the collectors 12 as well as a shield plate 26 and the interrupter switch 25 may be provided in the rectifier circuits. The air in the neighbourhood of the collectors 12 may be dried by a heating element 27 placed in front of a reflector 28, Counter-charging electrodes may be arranged in front of the collectors 12 so that the materials may pass through a field between the countercharging electrodes and the repelling electrode before passing into the field between the latter and one of the collectors.

IPC: C10G11/02
Filed: 1917-09-27
Abstract: 119,284. Mandle, H. H. Sept. 27, 1917. Hydrocarbons, cracking.-Hydrocarbon oils of a relatively low boiling-point, such as gasoline, benzene, toluene, &c., are obtained from heavier oils of a high boiling-point by mixing the heavy oil in predetermined proportions with water, spraying the mixture into a heating chamber or tubes heated to a temperature of from 250 to 675‹ C., and subjecting the mixture to the action of a catalytic agent consisting of an alloy of nickel, chromium, and steel placed at the outlet end of the chamber or tubes, the mixture being then passed through an oil-cooled primary condenser for removing the uncracked oils and a watercooled secondary condenser for condensing the hydrocarbons of lower boiling point. The alloy may be in the form of woven wire or may be included in the composition of the walls of the cracking-tubes, or a stirrer or scraper may be made of the alloy. The pressure in the heating chamber or tubes may vary from atmospheric to 600 lb. per sq. in. Fig. 1 shows one form of apparatus. Oil is pumped from a stock tank 2 through a pipe 4 to the upper part of the primary condenser 1, and the overflow is returned to the tank 2 through a pipe 5 provided with valved connexions 6 arranged at different heights on the side of the condenser 1. Water is similarly supplied to a secondary condenser 7 from a stock tank 8, and the cooling water and oil from the condenser are forced by pumps 12 through pipes 17 and sprayers 23 into the top of a series of cracking-coils 24 extending in a zigzag manner from the top to the bottom of a heating furnace 19. Each pump 12 comprises three elements driven from a common shaft, two for feeding the oil and one for feeding the water, the piston of the water feeding element being connected to the shaft by an adjustable connexion, e.g. by attaching the connecting-rod to a slot in an eccentric on the shaft. The coils 24 may be cleaned by forcing air therethrough by means of an air pump 26 connected to the top of the coils. The nickel alloy is inserted in the lower end of each set of coils through an opening closed 'by a cap 28<a>. The chamber 28 connecting the outlet ends of the coils is provided with a blow-off valve 28<b> and a tar pot 30 with an outlet valve 31. The cracked vapours pass from the chamber 28 to the two series of condenser tubes 34<a> in the primary condenser 1, each series consisting of five parallel tubes, and thence to an oil trap 36 from which the vapours pass to six tiers 42 of condensing- tubes in the secondary condenser 7. The valve 37 at the base of the trap 36 is opened by the weight of the oil when a certain amount has collected and the oil passed back to the store tank. The discharge from the second condenser 7 passes to a second measuring-trap 49 having a weightcontrolled valve 50 for discharging the hydrocarbons to the tank 56 and a pressure relief valve 51 for enabling the uncondensed gas to pass through a scrubber 53 to a gas storing tank 55. The gas may be used for heating the cracking-tubes.

Title: Heat resistant chromium-containing alloy steels and process for the production thereof
IPC: C21D3/04
Filed: 1938-05-12
Abstract: 516,867. Decarburizing alloy steels. WESTBERG, S. May 12, 1938, No. 14175. [Classes 72 and 82 (i)] Low-carbon chromium-containing alloy steels are produced by subjecting high-carbon chromium-containing alloy steel in a form having a large surface area, for example granulated, to a decarburizing heat-treatment in the solid state, at a temperature of 1,000C. or higher, in an oxygen-containing atmosphere until substantially the whole of the carbon present in the material has been removed. Before decarburization the material may be coated with an oxide such as lime or magnesia, and the operations of granulating and coating may be combined. In an example, a material containing about 80 per cent. of iron, 19 per cent. of chromium and 0.6 per cent. of carbon, produced as by melting together iron and ferro-chrome, is granulated, and if desired coated with lime or magnesia, and is heated in a current of oxygen and inert gas passing at such a rate that carbon monoxide is swept away as soon as it is formed. The product, which may contain 0.03 per cent. or less of carbon, is melted and heated with a deoxidizing agent such as silicon. Specifications 504,122 and 514,491 are referred to.

Filed: 1975-04-08
Abstract: 1501268 Matrix displays and circuits therefor INTERNATIONAL BUSINESS MACHINES CORP 8 April 1975 [7 June 1974] 14279/75 Heading G5C Driving signals applied to a matrix of liquid crystal display elements have relative phase angles of 2#/3, 0 and - 2#/3. The signals are combined to produce zero potential across selected elements and the same magnitude voltage across the remainder. A liquid crystal display device comprises crossed conductor arrays and crossed or parallel polarizing plates. A display is produced when the dielectric anisotropy is changed from positive to negative or vice versa by varying applied high and low frequency signals, e.g. from V H , V L  to 3V H , 0 or V L  to 0 with no high frequency signal. It is preferable to operate near the transition region to minimize the write time/decay time ratio whereby large matrices can be addressed. Both high and low frequency signals are applied to the panel in a line scanning mode. The low frequency voltage V<SP>1</SP> with a relative phase angle - 2#/3 denoted V<SP>1</SP>/ - 2#/3 is applied sequentially to the row conductors and a signal V<SP>1</SP>/-2#/3 to selected column conductors to produce zero voltage across selected cells 22. A signal V<SP>1</SP>/ + 2#/3 is applied to other column conductors to give voltages of magnitude V L  = #3.V<SP>1</SP> and various relative phase angles across the remaining cells. In a similar way high frequency signals V H /#, V H /0, 2V H /0 and 0 are applied as shown in Fig. 6b thereby obtaining 3V/ H 0 across the selected cell and V H  across the remainder.
