  • Production of epoxy compounds from olefinic compounds
    Patent number: 4008133
    Abstract: Olefin oxide is produced by reacting chlorine, obtained from an electrolysis cell, with a tertiary alkanol and an aqueous solution, containing sodium hydroxide and sodium chloride, obtained from the cathode of an electrolysis cell, to produce a tertiary alkyl hypochlorite. The hypochlorite is then reacted in a chlorohydrin reactor with an olefinically unsaturated compound and water, essentially free of chloride ions, to produce the corresponding chlorohydrin. The chlorohydrin is recovered and saponified with cell liquor, containing sodium hydroxide and sodium chloride, obtained from the cathode compartment of the cell to produce the olefin oxide.

  • Production of phenols
    Patent number: 4006194
    Abstract: Phenols are produced from .alpha.-aralkyl peroxides, preferably alkyl- .alpha. -phenalkyl peroxides or diphenalkyl peroxides, by heating the peroxide in the presence of an acid catalyst and continuously separating volatile reaction products other than the phenol; i.e., a carbonyl compound and alcohol if formed, from the reaction mixture, preferably by bubbling a stripping gas therethrough. Phenol may be produced from an alkyl benzene by reacting the alkyl benzene with t-butyl hydroperoxide to produce a t-butyl- .alpha. -phenalkyl peroxide which is then decomposed in the presence of an acid catalyst. The reaction co-products include t-butanol and a carbonyl compound corresponding to the alkyl group.

  • Injectors for the fuel injection systems of internal combustion engines
    Patent number: 4005826
    Abstract: There is disclosed an injector for a fuel injection system for an internal combustion engine and comprising a nozzle body formed with a compartment within which there is positioned a nozzle needle biased towards a closed position by a spring. A first chamber is formed between the valve seat and one end of a guide for the nozzle needle and a second chamber is formed at the other end of said guide, the arrangements being such that fuel under pressure is supplied to both said chambers simultaneously and that the nozzle needle is seated until the pressure in said second chamber is relieved by opening of a trigger valve under increasing fuel supply pressure to cause the nozzle needle to move to open the injection valve for the supply of fuel to the engine.

  • Compression bandage
    Patent number: 4005709
    Abstract: A compression bandage includes a bandage strip with an absorbent layer on one side. A pressure piece of slightly deformable and slightly absorbent molded material is attached to the other side of the strip opposite the absorbent layer.

  • Recovery of nickel and cobalt carbonates from ammoniacal leach solutions
    Patent number: 4002719
    Abstract: An ammonium carbonate leach solution containing dissolved nickel and/or cobalt values is sprayed into a flash chamber to flash a portion of the ammonia therefrom, resulting in the production of a fine precipitate of nickel and/or cobalt carbonate. The solution is introduced into a stripping tower wherein remaining ammonia is stripped therefrom to precipitate further nickel and/or cobalt carbonate on the previously precipitated carbonate, which function as nuclei to reduce deposition in the column.
