Title: Electrolytic method for treating an industrial waste water
IPC: C02F1/52
Filed: 1974-08-14
Abstract: 1475933 Electrolytic purification of aqueous effluent NIPPON STEEL CHEMICAL CO Ltd 14 Aug 1974 [17 Aug 1973 (3)] 35792/74 Heading C7B Waste water from a fossil fuel material-processing plant is electrolytically oxidized to reduce COD to 27-82% of its initial value, followed by treatment with active carbon. Insoluble or soluble electrodes are useful e.g. carbon, Pt, Pt/Ti, lead peroxide, a ferrite or a metal yielding Fe, Co, Ni, Sn, Zn or Cu ions. Such ions (e.g. 5-200 p.p.m.) may alternatively be added as a metal salt prior to electrolysis. The water may have pH 4-10 with added NaCl from sea water, and may be subjected before electrolysis to a flocculation or adsorbtion treatment, the latter using active carbon. Periodic polarity reversal is useful, in a mono or bi-polar cell. The carbon may be added as powder or the water passed through a fixed bed.

IPC: G01G7/02
Filed: 1956-11-23
Abstract: 816,453. Electric correspondence control. PNEUMATIC SCALE CORPORATION Ltd. Nov. 23, 1956, No. 35951/56. Class 40 (1). In a weighing-machine, the deflection of the armature of an inductive transducer under the influence of the load to be weighed produces an A.C. signal which operates means to indicate, record, or control the weight of the load. As shown, the feeding of material to be weighed from a hopper 90 into a carton 22 on a platform 20 deflects the platform against the restraint of leaf-springs 12, 14, and a coil-spring 24, thereby displacing a conductive non-magnetic loop 36 from its initial position, as set by an adjusting- nut 25, in the air-gap of an inductive pick-up 38, causing a differential output from the two secondary windings 48, 50, of the pick-up, which, when amplified at 54, is supplied via a relay 94 to a solenoid 98 which controls the feedgate of the hopper. Alternatively, the amplified pick-up signal may operate a voltmeter to indicate or record the weight of the load or to close an alarm lamp circuit if, when a camoperated supply switch is closed, the weight of the load is below or above a desired value. In Fig. 5 (not shown), a hopper having bulk and drip feed-gates is controlled by the amplified pick-up output which is fed to two relays in parallel; one relay, which operates to close the bulk feed-gate, comes up first, and the second relay closes the drip feed-gate at full load signal.

Abstract: 1,015,187. Ingition systems. BENDIX CORPORATION. Sept. 24, 1962 [Oct. 9, 1961], No. 36286/62. Heading F1B. An ignition circuit for an engine comprises two igniter spark gaps 47, 106 only one or both of which are to be operated depending on engine running conditions, a common storage condenser 82 for supplying energy to both igniter gaps from a voltage source through respective step-up transformers 42, 87 and a triggerable control gap device 97 including two parallel paths in the form of ionizable gaps between an input electrode connected to the storage condenser and two output electrodes 99, 109 respectively connected to the primaries of the transformers for energizing simultaneously both igniter gaps and another circuit path including one of the step up transformers for energizing a single igniter gap when the paths through the triggerable control gap device are cut off. A safety gap 56, 121 may be parallel connected with each of the igniter gaps. A source of 115 volts 400 cycle alternating current is adapted to be connected to terminals 10 and 11 a source of 14-30 volts direct current is adapted to be connected to the terminals 59 and 60. The parts of the circuit powered by alternating current and by direct current can be operated simultaneously but separate operation of each of such parts of the circuit is preferred. Thus when the ignition circuit is operated with a direct current source as during starting of the engine the alternating current supply is disconnected. The ignition system provides continuous stand by spark discharges. If therefore flame-out should accidently occur the engine will readily be started again almost immediately by the stand by ignition discharges.

Title: Improvements in aluminium oxide and in the manufacture thereof
IPC: C01F7/42
Filed: 1958-11-14
Abstract: Corundum (a  alumina) in filamentary form (see Group III) is used as a filler for synthetic resins.  According to an example 20% by weight of corundum fibres of 1 cm. average length and a length: shortest dimension ratio greater than 500:1 was incorporated in a polyester resin binder consisting of 33% monomeric styrene and 67% of propylene glycol maleate alkyd resin.ALSO:Fibrous or filamentary corundum having at least one dimension less than 50 microns and one dimension greater than 50 microns with an average ratio of longest to shortest dimension of at least 500:1 is prepared by heating aluminium in the presence of hydrogen and an inorganic silicon compound having Si-O bonds, at a temperature of at least 1100 DEG C. but less than the melting point of the corundum.  The aluminium metal may be in the form of powder, granules, foils, ingots, or turnings; suitable silicon containing compounds are silica gel and inorganic silicates, such as calcium metasilicate and orthosilicate, quartz, feldspars, micas, zeolites and mullite.  The hydrogen may be formed in situ by the reaction of water vapour with the aluminium.  The silicon compound may be mixed with the aluminium metal and hydrogen passed thereover, but preferably the silicon and aluminium are placed in thin layers in separate adjacent containers end to end in a refractor tube which, after heating to about 900 DEG C. is evacuated to 1 mm. Hg. or lower and then heated to 1100-1450 DEG C. whilst hydrogen is passed over. The corundum crystals form as fine fibres on or above the silicon - containing compound adjacent the aluminium. Alternatively a stream of argon containing water vapour may be passed over the silicon and aluminium reactants.  The reaction may also be effected in a closed system.  The corundum which forms on or above the silicon-containing reactant or the aluminium reactant, may be removed mechanically at the end of the reaction period.  It is particularly suitable as a catalyst support, as a filler for synthetic resins and as a filtering media for filtering, for example molten metals, at temperatures of 1000-1500 DEG C.ALSO:IV(a) Corundum (  alumina) in fibrous or filamentary form (see Group III) is employed for filtering molten metals.  For example, molten aluminium contaminated with oxides and dross, is sucked, at 700-800 DEG C into a rod-forming mould through a mat of compressed corundum fibres.  The rod so obtained is free from foreign inclusions.

Title: Improvements in or relating to the production of wear-resisting metallic articles
IPC: C22C1/05
Filed: 1934-12-24
Abstract: Wear-resisting articles for use as tools, dies, sand blast nozzles, contact points, well borers, and for other purposes, are made by alloying one or more carbide-forming metals such as tungsten, tantalum, titanium, zirconium, molybdenum, chromium, thorium, and rhenium, with one or more metals of lower melting point such as iron, manganese, nickel, cobalt, silver, and copper, carburizing or carburizing and boronizing the alloy so formed, powdering the product, mixing powdered metallic bonding material therewith, and bonding the constituents by heat-treatment.  The bonding material may be an iron-group metal which may be mixed as oxide with the powdered alloy, the oxide being subsequently reduced.  A preferred composition is a carburized or carburized and boronized alloy of tungsten and one or more iron-group metals bonded as described.  Alloys of refractory metals and the other metals referred to are powdered and heated with carbon or carbon and boron; the products are finely powdered and mixed with oxides of iron &c. heated in hydrogen, pressed to shape, and further highly heated, with or without pressure, in a carbonaceous, hydrogen, or reducing atmosphere.  In making the alloys, compounds such as cobalt oxide, iron oxide, and thorium nitrate, or cobalt tungstate, iron tungstate, and tungsten oxide may be used, the mixed powders being reduced in hydrogen.  The carburizing may be effected by mixing the alloy powders with lamp black and heating to about 950 DEG  C. in hydrogen, crushing and milling the product and reheating to about 1250 DEG  C. in a carbonaceous, hydrogen, or reducing atmosphere.  If boronizing is to be effected, boron suboxide or boron nitrate is used along with the lamp black.  The product is powdered and mixed with bonding material such as cobalt oxide and reduced in hydrogen at about 350 DEG  C.  It is afterwards shaped by pressure in moulds or by being mixed with an organic binder such as starch paste, gum arabic, caramel, or casein solution and extruded, the pieces being baked and then highly heated. The final product may contain 57,5-92,5 per cent of refractory metals, 0,25-5 per cent of iron, 0,25-2,5 per cent of chromium and thorium, 5-10 per cent of carbon and boron, and 2-25 per cent of cobalt and nickel.
