Patent GB-630484-A (GB)
Title: Improvements in or relating to polymerization process
IPC: C08F110/00
Filed: 1945-09-25
Abstract: Solid elastic products are prepared by a modification of the process of the parent Specification in which a low-boiling tertiary-base mono-olefine having not more than 7 carbon atoms per molecule is polymerized below -75 DEG  F. in the presence of a Friedel-Crafts metal halide catalyst associated with an alkali metal which is unreactive as a polymerization catalyst and is sufficient to react with all the hydrogen halide present.  The catalyst is not reactive with the alkali metal under the polymerizing conditions.  If desired the mono-olefine may be copolymerized between -75 DEG  and -200 DEG F. with a low-boiling conjugated diolefine having not more than 7 carbon atoms per molecule.  Specified tertiary base mono-olefines are isobutylene, 2-methyl-butenes, and methyl pentenes.  Listed conjugated diolefines are butadiene, isoprene, 1.3-pentadiene, 2.3-dimethyl-1.3-butadiene, cyclopentadiene and methyl cyclopentadiene.  Preferably the catalyst is employed as a finely-divided dispersion in the diluent employed for carrying out the polymerization, e.g. liquid propane or butane, or activated charcoal which has been coated with molten alkali metal may be p used.  Australian Specification 112,875 is referred to.

Abstract: 722,521. Cooling hot charges. POLYSIUS GES. Oct. 30, 1951, [Aug. 6, 1949.] No. 25386/51. Class 51 (2). Hot material from a rotary kiln, is cooled in a rotary cooling drum first by a cross-current of cold non- preheated air and then by a counter-current of cooling air. The drum shown for cooling cement clinker comprises crosscurrent cooling zone a and countercurrent cooling zone b separated by partition c, the zone a being equipped with elements d providing a number of compartments each of which is either provided with apertures e or is made of gas permeable material. The cooling air may be blown into these compartments either as shown or through apertures on the periphery of the drum. When blown as shown, a ring f, fixed to the drum and sealing the open ends of the compartments, is provided with the necessary air inlet apertures. This ring is covered by a slide g formed with air passages so arranged that the slide may be slid into positions such that only compartments covered with clinker are exposed to the cooling air from the blower. The slide may be replaced by any other equivalent closure member such as a hood. The heated air from zone a is used entirely or in part as combustion air in the kiln. The clinker passes from a through apertures h into chamber i from whence it is distributed to the cooling cells in zone b, cooling in this zone being effected by air drawn into a suction box k from the atmosphere through the cooling cells and an inner tube. The cooled clinker leaves the drum at m, any dust entrained by the counter-current cooling air being passed through the valve n to join the outgoing clinker. The hot air obtained from zone b may be used entirely or in part in the preheater of any kiln system equipped with such.

Filed: 1946-08-27
Abstract: 627,708. Feeding webs. BRITISH CELLOPHANE, Ltd. Aug. 27, 1946, No. 25619. Convention date, Aug. 28. [Class 100 (i)] [Also in Group XXIX] In a machine for unwinding a film from a supply roll, particularly in a machine for feeding film to slitting apparatus, the supply roll is mounted for axial adjustment and the film passes successively over two or more guide rollers also capable of axial adjustment, means being provided whereby, upon lateral deviation of the film, the supply roll and the guide rollers are moved axially in a direction opposite to the direction of deviation to restore the film to its proper path, each guide roller being moved a lesser distance than the roller preceding it. The supply roll is also moved a greater distance than the guide rolls. As shown, the machine comprises a supply roll 2 and two guide rollers 5, 6 all mounted for axial movement. The film runs in contact with a suction nozzle 8 so that as the film deviates, more or less holes 9 in the nozzle are covered, thereby changing the pressure inside bellows 13 connected to an armature which when displaced upwardly or downwardly by the bellows, opens either valve 17 or 18 connected by tubes 19, 20 to the cylinders of an air-motor 21. The opening of either valve 17,18 changes the air pressure within one or other of the cylinders so that pistons 22, 23 slide either to the left or the right, Fig. 1, by pressure from compressed air supplied by piping 29, 30 to to actuate lever mechanism 27, 36, 38 and thereby axially move the mandrel 1 of the roll 2. The movement of the mandrel axially moves the roll 2 and partially rotates a long lever 31 on a shaft 32 carrying a shorter arm 33 connected to the upper roller 5 and a still shorter arm 34 connected to the lower roller 6 so that corresponding and progressively shorter axial movements are imparted to the rollers 5, 6. The initial position of the nozzle 8 is adjusted by a rack 10 and the degree of vacuum in the system 8, 12, 13 is regulated by a valve so that with one line of holes 9 closed by the film, the bellows maintains the armature 15 out of contact with both valves 17, 18.

Abstract: 844,623. Velocity-modulated tubes. VARIAN ASSOCIATES. Oct. 5, 1956 [Nov. 14, 1955], No. 25773/59. Divided out of 844,621. Class 39(1). The gap spacing in a cavity resonator of a velocity-modulated discharge tube is varied around the periphery of the gap to compensate at least partially for the effect of an axialelectric component of the electromagnetic field set up in the resonator having its axis non- coincident with the axis of the electron beam and thereby to render the work done on or by an electron more uniform over the cross-section of the beam. In the arrangement shown, which is part of the tube described in Specification 844,621, the gap spacing is increased near the tuning plunger 28 by skewing the end of the upper drift tube section 12 to compensate for the shifting of the strong axial electric field to a point off the axis of the resonator 7 caused when the plunger 28 is extended into the resonator. Specifications 844,622 and 844,624 also are referred to.
