Title: Procedure for increasing the chemisorption capacity of carbon with regard to gases
IPC: C01B31/12
Filed: 1973-07-12
Abstract: 1431716 Improving absorbent carbon by irradiation INSTITUTT FOR ATOMENERGI 12 July 1973 [12 July 1972 25 June 1973] 33250/73 Heading C1A The chemisorption capacity of an absorbent carbon is improved by first impregnating it with a compound of a metal or mixture of such compounds and then irradiating the so impregnated carbon with gamma radiation at a dosage of at least 1 Mrad in a gaseous atmosphere comprising nitrogen. Preferably the carbon is impregnated with a copper compound, most preferably mixed with silver and chromium. The irradiation may be carried out at a partial pressure of nitrogen which is greater than the partial pressure of nitrogen in air at normal atmospheric pressure. The so prepared carbon may be used for absorbing toxic gases from gas streams. It finds particular use as the absorbent medium in a gas mask.

Abstract: 1,197,019. Soil working implements. MASSEY-FERGUSON Inc. 12 July, 1968 [14 July, 1967], No 33264/68. Heading A1B. An earthworking implement 1 is pivoted at the front and has a castor wheel at the rear and when the plough bottoms P are in working position the forces exerted by the soil move the implement into a diagonally offset position as shown. The castor wheel has locking means which operates when the ploughs are in the working position to directionally lock the castor wheel so that the trailing end of the frame is steered to the offset position, and which releases the castor wheel when the ploughs are in a transport position so that the frame assumes a normal trailing position. The castor wheel is mounted on an arm 25 which is pivotably connected by a spindle 24 to a U-shaped bracket 20. A control arm 42 is mounted on the arm 25 and has four adjustable stops which engage in pairs with one of the flanges 62 and (64) (Fig. 3, not shown). The flanges are connected via a bracket 52 to a sleeve 32 which rotates with respect to the draft frame member 6 and the castor wheel assembly 5. Mounted on the lower arm 22 of the bracket is a U-shaped bracket (74) (Fig. 3, not shown) which receives a latch rim (76) that can lock the control arm in line with the draft frame member 6 when the ploughs are in the transport position.

Title: Production of hydrated magnesium silicate decolorizing materials
IPC: B01J20/12
Filed: 1935-12-02
Abstract: Hydrated magnesium silicate is obtained by reaction between a soluble magnesium compound and a solid material containing calcium and silica in the presence of water and at elevated temperature. The solid material may comprise calcium silicate such as Wollastonite or as produced by fusion of lime and silica or by precipitation of a calcium salt by a soluble silicate, or calcium magnesium silicate such as diopside or as produced by fusion of calcined dolomite and silica, or basic or acidic slags, or Portland cement, or a mixture of silica with either unburned limestone, calcite, dolomite, dolomitic limestone or magnesite, hydrated lime, or hydrated calcined dolomite. Silica or lime are added when necessary.  The magnesium compound may be the chloride or sulphate or mixtures thereof.  The resultant calcium chloride is washed from the product, but calcium sulphate is allowed to remain.  Conditions may be arranged so that calcium silicate is present in the product, and sometimes iron and aluminium silicates are present.  The reaction mixture is preferably agitated, and the reaction may be effected under pressure.  The solid reaction materials are preferably finely ground.  The product may be spray-dried, and pulverized.  In examples, temperatures up to 500 DEG F. and pressures up to 500 lbs. per sq. in. are employed. Wollastonite may be initially ground to pass through a 325 mesh screen, or it may be fused, blown into a slag wool, and disintegrated by a fan type milling apparatus prior to treatment with the magnesium compound.  The product is used for decolorizing oils and aqueous liquids, and has a high filtration rate.ALSO:Hydrated magnesium silicate for use in decolorizing oils and aqueous liquids and having a high filtration rate, and obtained by reaction between a soluble magnesium compound and a solid material containing lime and silica, may be produced in admixture with other compounds.  Thus, if magnesium sulphate is employed, the product contains calcium sulphate.  Or the reaction may be so effected that calcium silicate is present in the product.  If for example, Portland cement is used as a starting material, aluminium and iron silicates will be present in the product.

Abstract: 945,715. Valves. GROVE VALVE & REGULATOR CO. Sept. 18, 1961 [Sept. 21, 1960], No. 33333/61. Heading F2V. A valve comprises a movable valve member 31, Fig. 3, having a seating surface which makes metal to metal contact with the valve seat 29. The valve member 31 is formed by two members 46, 47 between which is clamped a resilient ring 49 which projects from the faces 54, 55 of the member in the open position and is compressed on closing the valve to provide a seal. The inner end of the ring extends into a chamber 52 open to the downstream side of the valve, e.g. through the screw-thread by which the parts 46, 47 are connected. The ring may be located between two valve seat parts instead of the movable closure member. As shown in Fig. 1, the invention is applied to a valve in which the valve member 31 is connected to a diaphragm 13 which is subjected to a fluid pressure loading in housing 15 and to the outlet pressure through passage 25.

Title: Method for the purification of metals and metal alloys
IPC: C22B9/10
Filed: 1933-11-28
Abstract: To eliminate gases such as hydrogen, carbon monoxide and dioxide, nitrogen and cyanogen dissolved in metals or metal alloys by oxidation oxides of the metals or oxygen compounds adapted to form the oxides are added to a bath of the metals or alloys in such proportion that the content of the metallic oxide thus added or formed is less than that of its corresponding metal-metallic oxide eutectic, the oxidation taking place in the presence of a element less noble than the metal or the principal metal of the bath.  A less noble element is added to the bath should such not be originally present; for example zinc or phosphorus is added to the bronzes of tin before oxidation and the oxidation is conducted in such manner that traces of zinc or phosphorus remain.  Sulphur is eliminated either as a preliminary or simultaneous operation through the medium of a double carbonate of barium and sodium; this treatment is carried out in an oxidizing atmosphere in the case of alloys containing tin or zinc and as a preliminary treatment with a reducing medium in the case of copper nickel alloys.

Title: Purification of n-vinylcarbazole
Inventor: MILLER SAMUEL AARON
Filed: 1956-11-05
Abstract: N-Vinylcarbazole, derived from a coal-tar source, is purified by heating at above its melting point but below 120 DEG  C. with from 0.25 to 2.5 per cent by weight of an azo compound or azo compounds which furnish free radicals at the reaction temperature.  The process is stated to substantially reduce the amount of impurities which interfere with the polymerization of the N-vinylcarbazole in the presence of an azo catalyst with or without a peroxide.  The treated product may be recrystallized.  Specified azo compounds are 2,21 - azobisisobutyronitrile, (CH3)2C(CN).N : N(CN)C(CH3)2, and 2,21-azobis (methyl isobutyrate), (CH3)2C(COOCH3).N : NC (COOCH3)(CH3)2. Reaction times of 15-45 minutes are generally useful.  An example describes the preparation of N-vinylcarbazole containing sulphur compound impurities by the reaction of acetylene with coal tar carbazole and its purification by heating with azobisisobutyronitrile; the methanol recrystallized product is polymerized in the presence of azobisisobutyronitrile and di-t-butyl peroxide.
