Title: process for polymerizing ethylenically unsaturated compounds
IPC: C08F4/32
Filed: 1963-07-26
Abstract: Ethylenically-unsaturated monomers are produced by a process which comprises forming a film containing the monomer and bringing together within the film sulphur dioxide and an organic hydroperoxide. Preferably a film-forming polymer is dissolved in the monomer containing one component of the catalyst combination; then a film is made of this composition, which film is then contacted with the other catalyst component.  In examples, polymers such as cellulose acetate butyrate, polyvinyl acetate, polymethyl methacrylate, polymethyl acrylate, polyoctyl acrylate, polydiethylene glycol sebacate and a copolymer of acrylonitrile and methyl acrylate are dispersed in monomers such as methyl and ethyl acrylate, methyl methacrylate, acrylonitrile, ethylene glycol dimethacrylate and diacrylate, N-isopropylacrylamide, diethylene glycol diacrylate, and 1,1,1-trimethylol propane thiacrylate, spread into a film, and polymerized on contact with sulphur dioxide.  Alternatively, a film can be formed comprising a monomer and hydroperoxide and a second film can be formed comprising the same or different monomer and sulphur dioxide; the two films will then polymerize together on being placed in contact. The film may be formed on panels made of steel, wood, plastic &c., or may be formed on filaments made of, for example, polypropylene and copper.  Polymerization may also take place in the presence of fillers and stabilizers.

Title: Improvements in or relating to the production of filaments of vinylidene chloride polymers and copolymers
IPC: D02J1/22
Filed: 1947-11-11
Abstract: <PICT:0649539/IV (a)/1> Filaments are made from vinylidene chloride polymers and copolymers by forcing a continuous rod of the resin while in amorphous, supercooled condition and at a temperature between normal temperatures and 175 DEG  F. through an opening of reduced diameter and simultaneously drawing the rod through the opening so as to reduce the rod to a uniform filament.  As shown, the rods 21 are forced through the die 15 by rollers 22 and 23 and drawn by rollers 25 and 26.  The rods 21 may be preheated to between 125 DEG  and 175 DEG  F. by high-frequency electric currents or by infrared heat lamps.  A series of dies may be used or a series of sets of rolls and dies.  Suitable materials are vinylidene chloride or copolymers of vinylidene chloride with small proportions of vinyl esters, ethers or ketones, cyclic substituted unsaturated compounds, e.g. styrene, indene and coumarone; conjugated compounds, e.g. butadiene and isoprene or other compounds, e.g. acrylonitrile; such as a copolymer of 95-85 per cent vinylidene chloride with 5-15 per cent vinyl chloride.  The Specification as open to inspection under Sect. 91 describes also the use of rolls without dies or alternatively the omission of the rolls 22 and 23, the filaments being drawn through the dies by the rolls 25 and 26. 2,3-Dichlorbutadiene-1,3 may be used instead of vinylidene chloride. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to temperature responsive control mechanisms
IPC: H01H61/06
Filed: 1950-12-13
Abstract: 689,069. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. Dec. 13, 1950 [Dec. 29, 1949], No. 30444/50. Class 38 (v) [Also in Group VI] A temperature-responsive control mechanism comprises a bimetallic element having a freely-movable section deflected when current is passed through electric heating means intimately associated with the element, a switch operated in response to deflection of the section to supply current intermittently to the heating means, a rotatable shaft with clutch means allowing free unidirectional rotation and means for cyclically rotating the shaft in the direction of its free rotation in response to the deflection of the section. One end of a bimetallic element 2 supported on base plate 1 by bracket 3, engages adjustable screw 5. A resistor 6 is wrapped round element 2 and is connected directly to the power supply at one end 6 while the other end is connected through a lead 8 and terminal 9 to column spring 10 which in one position engages contact 11. The column spring 10 is held by terminal 9 and bracket 13 to give a snap action and is biased towards the closed position of contact 11 by a spring 17 engaging a support 18. The spring 17 is axially aligned by the reduced extension 21 of a rod 19, the other end of which has a reduced extension 34 forming a shoulder 20a which engages the bimetallic element 2 and extends therethrough. As the bimetallic element is heated it bends and pushes rod 19 and spring 10 against the action of spring 17 until the spring 10 snaps over and breaks the circuit; the bimetallic strip then cools down until the spring 10 is snapped back by spring 17 and the circuit is completed again. A shaft 23 is rotatably mounted on base plate 1 and is engaged by two clutches 24, 25; clutch 24 having an arm 26 secured to a pin 27 fastened to the base plate 1 and allowing only clockwise movement of the shaft as viewed from dial 22 and clutch 25 having an arm 28 by which the shaft 23 may be driven clockwise. Arm 28 carries a pin 29 held in engagement with bimetallic element 2 by spring 30 so that the shaft 23 is rotated a small amount each time the bimetallic strip is heated. The cycles of heating and cooling continue until a cam 33 on shaft 23 engages a collar 32 on rod 19 and prevents spring 10 from returning to the closed position until the cam is manually moved clockwise past the collar.
