Title: Process for preparing predominantly crystalline alpha-olefin polymers
IPC: C08F6/24
Filed: 1964-08-28
Abstract: A process for preparing predominantly crystalline a -olefin polymers comprises polymerizing an a -olefin in a hydrocarbon dispersing medium to give an a -olefin polymer containing at least 2% by weight of an atactic fraction which polymer is in the form of a slurry in the dispersing medium, introducing the slurry intro a treating zone, introducing into the treating zone in liquid form a hydrocarbon solvent medium containing 1 to 5 carbon atoms per molecule in amount of 0.5 to 10 pounds of solvent per pound of polymer at a temperature ranging from 40 DEG  to 250 DEG  F. and sufficient to dissolve the atactic fraction and recovering from the treating zone at least two separate streams, one comprising a hydrocarbon solvent medium stream containing atactic polymer in solution and the other comprising a slurry stream of a hydrocarbon dispersing medium and a predominantly crystalline a -olefin polymer.  Specified olefins are ethylene, propylene, butene-1, penten-1, 3-methylbutene-1, 4-methylpentene-1, 5-methylhexene-1 and styrene.  The dispersing medium may be a saturated or unsaturated hydrocarbon containing 1 to 5 carbon atoms, e.g. alkanes or excess monomer.  The solvent medium is a saturated or unsaturated hydrocarbon containing 1 to 5 carbon atoms, e.g. methane, ethane, propane, butane and pentane.  Preferably the dispersing and solvent media are the same.  The solvent medium may be introduced counter-currently to the dispersing medium in the treating zone.  The solids may be recovered from the separated streams by flashing. Apparatus suitable for carrying out the process of the invention is described and illustrated. Specifications 799,392, 810,023 and 828,791 are referred to.

Title: Improvements in or relating to methods of or machines for operating on soles for boots or shoes
IPC: A43D43/02
Filed: 1938-12-08
Abstract: 522,212. Channelling soles. BRITISH UNITED SHOE MACHINERY CO., Ltd., BRAY, W. N. and BAGSHAW, C. M. Dec. 8, 1938, No. 35755. [Class 31 (i)] To prevent a leather insole for a welt shoe being pulled out of shape when 'the insole lips areraised and cemented together, the channelling machine is provided with means for making a lip-slashing cut at intervals of say three feeds, which intervals may become automatically longer as the length of feed is decreased at the toe so that the interval between slashes is substantially uniform. As applied to the machine described in Specification 13052/08, [Class 31], a pair of slashing knives are provided arranged to descend on the insole on either side of the material between the lips after a predetermined number of feed movements, the slashes being made just before the channelling knives reach 'the portions slashed. The slashing knife 1 cuts the inside channel and is carried by a rod having a roll 33 engaging a slot in a bracket 31 adjustably secured to a block 23 itself secured to a sliding rod 17 which may be shifted slightly about its axis so that the slash of the marginal slashing knife 3 is carried by the rod -is inclined to the direction of feed. The block 23 is reciprocated by a roll on an arm 59 secured to a shaft 61 to which is also secured an arm 71 having an arc shaped surface 73 co-operating with a roller 79 urged upwardly by a spring against a stop 89 and engaging a recess in one arm 77 of a bell-crank lever 75 freely mounted on the shaft 61 and carrying at its other end a latch 95 cooperating with a block 97 at the end of a lever 99 swung by a cam at each feed. The latch is urged away from the block by a spring 103 but is moved to operating position by a plunger 117 when a step 115 on a ratchet wheel 105 free on the shaft 61 engages the plunger. The lever 99 actuates the ratchet wheel one step at each stroke, by a pawl 109. A lug 123 on the lever 75 frees the pawls when the lever is swung and allows the ratchet wheel to be returned to starting position determined by a screw 125 on the wheel and a pin 127 on an arm loose on the shaft 61. This arm is linked to an arm 133 connected to the treadle for reducing the length of feed described in the prior Specification, so that the pin 127 is moved as the feeding stroke is lessened to keep the interval between slashes substantially uniform, say five eighths of an inch. The edge of the knife 1 may slope downwardly and rearwardly to correspond with the angle of the channelling cut. Specifications 10299/13, and 302,382, [both in Class 17 (i)], also are referred to, According to the Provisional Specification, 'the two slashing knives are carried by a single bar, and a ratchet rack is used instead of a ratchet wheel for determining the interval between slashes.

Abstract: A composition comprising polyethylene, a filler and 1 to 10 per cent by weight of a curable organopolysiloxane, based on the filled polyethylene, has improved extrusion properties of flow, smooth surface and less nerve, and improved ageing characteristics. Polyethylene of high or low pressure type may be used and the curable organopolysiloxane may be obtained by condensing a liquid organopolysiloxane with 1.9 to 2.1 silicon bonded organic groups per silicon atom, e.g. of formula R2SiO where R is a methyl or phenyl radical, such as (CH3)2SiO or a copolymer of dimethylsiloxane and a minor amount of C6H5(CH3)SiO and (C6H5)2SiO, with condensing agents such as ferric chloride hexahydrate, phenyl phosphoryl chlorides, quaternary phosphonium hydroxides and alkoxides, solid quaternary ammonium hydroxides and potassium and caesium hydroxides and in an example octamethylcyclotetrasiloxane is heated for six hours with potassium hydroxide to form a gum.  Fillers may be finely divided silicas, e.g. xerogels, aerogels, fumed and hydrophobic silicas, calcium silicates, aluminas and carbon blacks.  Cured compositions may be obtained either by including 0.1 to 20 per cent of a peroxide, such as di-a -cumyl peroxide in the composition and heating at 150 DEG  to 200 DEG  C.; by extruding the composition into a solution containing a peroxide and heating whereby a bulk extrusion is case hardened or thin films or filaments cured throughout; or by high energy radiation.  The compositions may be extruded on wire as insulation, or with carbon blacks used as heat stable heating pads or tapes.

The starting materials are obtainable by the process of Specification 637,924, and the products may be used for the synthesis of biotin as described in Specification 606,196.  In an example, 2-(41-carbomethoxybutylidene)-3-(p - nitrophenylhydrazino) - 4 - benzamidotetrahydrothiophene is treated with zinc dust, acetic acid and acetic anhydride to produce 2-(41-carbomethoxybutyl)-3-acetamido-4-benzamido-4 : 5-dihydrothiophene; the product or its isomer may be converted to the corresponding acids by saponification with warm alkali in aqueous alcohol and acidification of the product.  Additional starting materials specified are esters of 2-a 41-carboxybutylidene-3-(p-nitrophenylhydrazino) -4-acetamido- and 4-propionamido-tetrahydrothiophene, and 2-(41-carboxybutylidene) - 3 - semicarbazido - 4 - benzamidotetrahydrothiophene, and its is stated that R11 may also be ethyl, propyl, butyl, phenyl or benzyl.
