Title: Amorphous rubbery copolymers of ethylene and higher alpha olefins
IPC: C08L23/16
Filed: 1958-06-24
Abstract: Rubbery amorphous copolymers comprise 15 to 85 mole per cent ethylene and 85 to 15 mole per cent higher alpha olefin.  The copolymers may be prepared by at least partially reducing a heavy metal compound with an amount of a reducing agent sufficient to reduce the metal compound to a next lower valency level, activating the reduced heavy metal with an organo-metallic compound and contacting the activated catalyst with a feed containing 15-85% ethylene and 85 to 10% of a higher alpha olefin. The reducing compounds specified include the alkyl and aryl aluminium organo-metallic compounds, and the alkyl, aryl and hydride derivations of the Group I, II and III elements. The heavy metal compounds include the halides, oxyhalides, complex halides, oxides, hydroxides, alcoholates, acetates, benzoates and acetylacetonates of the Group IV, V, VI and VIII transition metals. Diluents such as aliphatic, hydroaromatic, aromatic and halogenated aromatic hydro-carbons may be present.  Specified higher alpha-olefins are propylene, butene-1, pentene-1 and hexene-1.  The catalyst may be deactivated by the addition of alcohol, e.g., methyl, isopropyl or normal butyl alcohols.

Title: An improved process for the isomerisation of paraffins
IPC: C07C5/27
Filed: 1944-10-20
Abstract: <PICT:0592446/IV/1> In the isomerization of normal paraffins by passage in the vapour phase through a bed of aluminium halide on a porous carrier, fresh aluminium is added only to that part of the bed separated from the feed inlet by the aluminium halide-hydrocarbon sludge formed, the feedstock thereafter being passed through the whole bed.  A paraffin feed such as n-butane is fed through heater 13 and aluminium chloride pick-up vessel 17 to reactor 20 at about 200-350 DEG  F., entering by line 18 below a grid 22 supporting a porous bed 21, for example of activated bauxite, for absorbing the aluminium chloride.  When impregnation is sufficient, the vessel 17 is byepassed, and butane fed direct to reactor 20, a promoter such as hydrogen chloride being added from line 25.  Impurities in the feed form a sludge in the lowest part 28 of the bed 21. Isomerization products leave at 27 for recovery.  Reactivation of the catalyst is effected by addition of aluminium halide from vessel 17 in the butane stream, section 28 being byepassed by closing valve 19, and opening valve 29 in line 30.  Butane only is then fed through the catalyst via line 18 and valve 19, the section 28 acting as a purifier. Periodically, this section may be reactivated with small amounts of aluminium chloride.  If the sludge reaches above grid 31, make-up aluminium chloride may be introduced at progressively higher levels through valves 32 or 36, and the isomerization feed through valves 35 or 38.  Inert gas may replace the butane for introducing make-up aluminium chloride whereby the upper part of bed 21 is kept sludge free.  Impurities may be added to the feed hydrocarbons to hasten formation of sludge in section 28.

Abstract: 748,831. Coating by vapour deposition. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 22, 1954 [July 22, 1953], No. 20411/53. Class 82(2). A vacuum vaporisation apparatus comprises means for feeding a uniformly wide sheet or foil of the material to be vaporised to a linear vaporising element, having a length at least equal to said width, so that the forward edge of the sheet contacts the element along the whole or a substantial portion of the length of said element. Preferably, the sheet or foil is drawn from a roll and fed through a slot in a reflector plate associated with the vaporising element, the rate of feed being controlled so that the material fuses over the element before being vaporised. As shown, the reflector 5, made of two strips of tantalum, has lips 11 to form a guide slot through which foil 12, e.g. aluminium, is fed by rollers 13, 14 to the vaporising element 4. The working parts of the apparatus may be water-cooled and in a modification of the apparatus, the rollers 13, 14 and the guide slot are re-arranged so that the foil is fed vertically downwards on to the element 4. Alternatively, the rollers may be constructed of a high melting- point material, such as tungsten, and arranged close to the element. Specifications 485,965 and 740,271 are referred to.
