Title: Compositions comprising acrylonitrile polymers and copolymers and shaped articles produced therefrom
IPC: C08J3/09
Filed: 1945-11-19
Abstract: Compositions suitable for making yarns, films and shaped articles comprise a solution of polyacrylonitrile or a copolymer in which at least 85 per cent by weight is acrylonitrile, in a solvent comprising N.N-dimethylcyanamide.  The compositions are clear mobile solutions at elevated temperatures, e.g. 100 DEG  C., and gel at room temperature.  In small amounts the dimethyl cyanamide acts as a plasticiser for the polymer.  Specified compounds with which the acrylonitrile may be copolymerized are vinyl acetate and chloride, acrylic acid and its esters and homologues, styrene, isobutylene and butadiene (see Group V).  Optionally, the compositions may contain other plasticisers (non-solvents for the polymer), e.g. glycerine and dyes, linear polyamides, cellulose ethers and esters, polyvinyl chloride and acetate and polyacrylic acid.  The solutions may be shaped to form filaments, yarns, films, tubes and other articles by moulding, casting or extrusion into an evaporative atmosphere or a bath of coagulant miscible with the solvent, but an inert non-solvent for the polymer.  The properties of the articles can be improved by a subsequent stretching operation.  Specifications 404,504, 585,368 and 594,999 and U.S.A. Specifications 2,117,210, 2,140,921 and 2,167,537 are referred to.ALSO:Compositions suitable for making yarns, films and shaped articles comprise a solution of polyacrylonitrile or a copolymer in which at least 85 per cent. by weight is acrylonitrile, in a solvent comprising N.N-dimethylcyanamide [see Group IV].

Title: Broaching method and machines therefor
Inventor: POYNTER CYRIL EDWARD
IPC: B23Q5/06
Filed: 1948-11-30
Abstract: 653,552. Broaching. WEATHERLEY OILGEAR, Ltd. Nov. 30, 1948, No. 31094. [Class 83 (iii)] In a broaching-machine in which, during a single working stroke, the finishing cut is made at a slower speed than the initial roughing cut, the reduction in speed is made by automatic alteration of the stroke of a variable-displacement pump 6. The pump stroke is reversible and its stroke is altered by pistons 9, 10, 11 under the control of solenoid-operated valves 22 and 30 which are operated by switches LS actuated by dogs 34, 35, 36 on the tool-holder 3. When the tool-holder 3 is in its uppermost position, a valve 22 is in mid-position and pressure from a pump 15 acts on pistons 9 and 11 and, since the piston 9 is the larger, they are moved to set the pump 6 at low delivery from port 8, as determined by the engagement of a collar 9A on the piston-rod with the head 19 of an adjustment screw screwed into the cylinder body; the space in front of piston 10 is connected to drain and the output of the pump is byepassed through a valve 30 to suction port 7 of the pump. When the electrical circuit is energized to supply current to the solenoids 28, 31, valve 30 closes and valve 22 moves to the right, thus allowing pressure from pump 15 to move piston 10 to set the pump for rapid delivery from port 8 to the ram 5, at a rate set by an adjusting screw 18, until cam 35 operates switch LS3, thus de-energizing solenoid 28. Valve 22 then moves back to mid-position and the pump delivery is reduced to the former slow rate to give the finishing cut. At the end of the working stroke, cam 34 operates switch LS1 to energize solenoid 27, thus moving the valve 22 to the left, draining the spaces in front of pistons 9 and 10 and allowing piston 11 to set the pump for delivery from port 7 to return the ram 5, at a rate determined by an adjustment screw 20 engaging the top of piston 9. At the end of the return stroke, cam 36 and switch LS2 deenergize the solenoids 27 and 31 to restore the valves 22 and 30 to their original positions. A third control piston may be fitted in the lefthand control cylinder of the pump to operate in place of the valve 29 and a further piston may be added to the right-hand control cylinder so as to give two adjustable deliveries from port 7 of the pump, for application to a duplex machine.
