Title: Improvements in and relating to the catalytic polymerisation of olefins
IPC: C08F10/00
Filed: 1960-08-15
Abstract: Polymers of alpha-mono-olefines containing at least three carbon atoms in the molecule are made by polymerizing one or more of the monomers in the presence of a catalyst comprising titanium trichloride and an aluminium alkyl compound, and sufficient of a zinc dialkyl and/or diaryl compound to produce a polymer whose molecular weight is substantially lower than that of a polymer produced in the absence of said zinc compound under otherwise equal conditions.  The polymerization may also be effected in the additional presence of an aliphatic tertiary or secondary amine having at least five carbon atoms per molecule, an aliphatic primary amine having at least 4 carbon atoms per molecule, or a heterocyclic nitrogen compound having 5- or 6-membered rings and an alkyl substituent of up to 6 carbon atoms on one or both carbon atoms alpha to the nitrogen atom in the ring.  The polymerization is generally carried out in the presence of an organic solvent or diluent such as benzene, heptane, or iso-octane.  Mono-olefines specified are propylene, 1-butene, 1-pentene, 3-methyl-1-pentene, and 1-decene.  The polymerization may also be carried out in the presence of ethylene, e.g. to give a copolymer of propylene and ethylene.  The zinc dialkyls and/or aryls may be added to the catalyst, or at any stage of the reaction.  If desired, they may be formed in situ, e.g. by adding a zinc compound, such as the fluoride or stearate, which interacts with the aluminium alkyl of the catalyst to form a zinc alkyl and an aluminium salt. The titanium trichloride of the catalyst may be a commercial product, but preferably it is formed by reducing titanium tetrahalide with an aluminium trialkyl in a two stage process until the mol. ratio of total aluminium to titanium is 1:1, or by partially reducing titanium tetrahalide with an aluminium trialkyl and subsequently completing the reduction to give the above ratio by using a dialkyl aluminium chloride.  The organo zinc compound may be zinc diethyl, di-n-propyl, di-isopropyl, di-isobutyl, di-isoamyl, diphenyl or ditolyl.  The organo-aluminium compound of the catalyst may be aluminium diethyl chloride, aluminium diethyl bromide, aluminium triethyl, aluminium tri-isobutyl, or aluminium tri-isopropyl.  Triethyl amine is the exemplified nitrogen-containing compound.  The polymer is recovered from the polymerizate by conventional techniques.  Specifications 799,823 and 810,023 are referred to.

Title: Improvements in or relating to the manufacture of metal articles or masses
IPC: C22C33/02
Filed: 1937-10-18
Abstract: In a process for making metal masses or articles, for example gear wheels, moulds, engine and machine parts, bombs, carbon dioxide cartridges, and many others, a powder consisting of a normally brittle alloy of iron and carbon, such as white cast iron, is sintered, with or without the application of pressure, the heating being effected in presence of a small proportion of an impurity which is commonly present in the alloy or is added thereto and has a bonding action on the particles during heating. The impurity or addition may be phosphorus, an alloy rich in phosphorus, a copper alloy, arsenic, antimony, or a mixture of copper and tin.  In some cases the particles may be oxidized on the surface before or during the heat treatment, and oxides such as magnesia, silica, alumina, or titanium dioxide may also be present.  Other elements which may be present include nickel, chromium, titanium, molybdenum, vanadium, silicon, and sulphur. Bodies may be formed having localized areas of one composition embedded in or surrounded by areas of another composition, or they may have embedded in them preformed components.ALSO:In a process for making metal masses or articles, for example gear wheels, moulds, engine and machine parts, bombs, carbon dioxide cartridges, and many others, a powder consisting of a normally brittle alloy of iron and carbon, such as white cast iron, is sintered, with or without the application of pressure, the heating being effected in presence of a small proportion of an impurity which is commonly present in the alloy or is added thereto and has a bonding action on the particles during heating.

The front of this flue is closed by a curved plate q seating on ribs p, the burner r being arranged in front of it. In a modification, the rear flues are formed by a flue box secured on the outside of the back of the oven.

Abstract: 1,261,715. Variably bulked yarn. COURTAULDS Ltd. 16 June, 1969 [17 June, 1968], No. 28651/68. Headings D1F and D1W. Apparatus for variably bulking continuous filament yarn comprises a bulking jet 2, means, e.g. nip rollers 3 for feeding continuous filament yarn 1 to the jet 2, means for collecting the bulked yarn over end on a package 6, a brake 9 for braking the yarn between the jet 2 and the yarn collection means, and means for intermittently operating the brake 9. The brake 9 may comprise a pair of closable jaws which straddle the yarn path or a pair of rods 10, 11 which are movable relative to each other to alternately grip and release the yarn 5. In a particular embodiment, the rubber covered rod 11 is mounted on an arm 12 pivoted at 13 and movable into arid out of contact with the metal rod 10 by means of a rotatable cam 14. The yarn may be bulked according to a random or a patterned sequence. The braking of the yarn causes an overfeed of yarn to the jet and thus a bulking of the yarn, the yarn being collected by for example a ring spinner 7 at a rate which produces no substantial overfeed of yarn to the jet when the yarn is not being braked. The yarn is preferably formed of continuous filaments of cellulose acetate, cellulose triacetate or nylon.

Title: Preparation of fluorinated perhaloaldehydes
IPC: B01J23/26
Filed: 1965-07-06
Abstract: Fluorinated perhaloacetaldehydes are made by heating, in the vapour phase at 200-500 DEG  C., anhydrous hydrogen fluoride and a perhaloacetaldehyde in which the halogens are Cl or F, at least one being Cl, using at least one mole of hydrogen fluoride per mole of perhaloacetaldehyde, in the presence of an activated anhydrous chromium (III) oxide catalyst.  It is usual to employ hydrogen fluoride in an excess of the stoichlometric amount required, as the degree of fluorination is primarily dependent upon the reaction temperature, catalyst and flow rate. The fluorinated perhaloacetaldehydes are obtained as complexes with hydrogen fluoride which can be decomposed by treatment with activated sodium fluoride. Examples relate to trifluoroacetaldehyde.
