Title: Improved process for the low temperature polymerisation of olefins
IPC: C08F210/12
Filed: 1944-07-12
Abstract: In a process of preparing high molecular weight polymers by polymerizing in a reaction zone an isoolefin, e.g. isobutylene or a mixture of a major proportion of an isoolefin and a minor proportion of a conjugated polyolefin, e.g. isoprene, piperylene dimethyl-butadienes and myrcene in a diluent at a temperature below -40 DEG  C. in contact with a Friedel-Crafts type catalyst to form a slurry of solid polymer particles in cold reaction liquid, separating the solid polymer particles from the cold reaction liquid at substantially the reaction temperature and returning the latter to the reaction zone, an improvement comprises transferring the separated polymer particles to a flushing zone concurrently with a stream of sealing gas sufficient to prevent backing up of flashing gases into cold equipment.  Hot liquid in the flashing zone is preferably water at 130 DEG  to 160 DEG  F., and the sealing gas may be natural gas, hydrogen, methane or nitrogen.  Referring <PICT:0589045/IV/1> <PICT:0589045/IV/2> <PICT:0589045/IV/3> <PICT:0589045/IV/4> to Fig. 1, cold slurry from the reaction vessel overflows through line 11 via weir box 14 on to vibrating screen 13 in chamber 12. The cold liquid passes through the screen to trough 15 and hence out of chamber 12.  The polymer particles fall from the end of the screen into a vibrating hopper 22 and via pipe 23 into the heated liquid in flash chamber 21.  Sealing gas is supplied via chamber 12 from either or both of pipes 29 and 30.  The flashed-off gases leave chamber 21 via pipe 32 and the polymer via line 33, rollers 35, 36 and 37, picker roll 39, conveyer feed 40, belt 41 and tunnel drier 42.  In Fig. 2, the polymer enters casing 102 and drops on to screen 101 and so to vibrating feeder 105 and flash chamber 108 which has a turbine-type mixer 109, a water inlet pipe 110 and steam header 111.  The polymer slurry passes under weir 113 and overflow weir 112 and the sealing gas is introduced via line 115.  Fig. 3 shows an embodiment with a screen conveyer 202 between the screening enclosure and the flashing chamber.  In Fig. 7, slurry enters at 504 and passes via shoot 505 to vibrating screen 501 supported by spring suspension 516 and vibrated by electromagnetic vibrator 508. Examples of the treatment of an isobutylene-isoprene copolymer with methyl chloride as diluent and of an isobutylene-butadiene copolymer are given.

Combined fluid-actuated and mechanical gears. -In the construction shown, the auxiliary valve is arranged in a slot 11<b> in the main valve 11, and is arranged to move: the main valve to the middle of its stroke, the motion being completed by fluid pressure. The auxiliary valve, prior to moving the main valve, puts it in equilibrium. The inlet 2 is connected by a passage 5 to inlets 6, 6<a>. The exhaust 3 is connected by a passage 8 to the outlets 7, 7<a>. Ports 9, 10 arranged between the inlet and outlet, passages communicate through passages 9<a>, 10<a> with the cylinder. The main valve has annular recesses 11<a>, and the auxiliary valve, which is in the form of a piston with two flat sides, has pairs of ports 13, 14 connected by balance passages 15. Passages 17, 18 connect ports 17<a>, 18<a> in the valve-chest ends with pairs of ports respectively arranged at the centre of the chest. On the opposite side of the chest, auxiliary supply ports .are provided connected to the main supply by a passage 23, and auxiliary exhaust ports, which are connected to the exhaust ports 7, 7<a>. The pressure on the valve-spindle is balanced by the pressure on an auxiliary plunger 27. The first movement of the auxiliary valve, Fig. 1, closes the lower end of the chest to exhaust, and then admits steam to the lower end and simultaneously to the upper end to balance the valve. The auxiliary valve then moves the main valve until it arrives at its mid position, when it puts the upper end of the chest to exhaust. The movement of the main valve is completed by the pressure at the lower end of the chest. Each of the auxiliary exhaust passages in the liner may be fitted with a plug valve to regulate the velocity of movement of the main valve. In a modification, the main valve is in two parts connected by rods which pass through the auxiliary valve. In a further modification, the valves are arranged in two chests side by side and connected by spindles to a common lever. Lost motion is provided between the main valve and its spindle.

Abstract: 475,099. Photographic exposure meters. KODAK, Ltd: May 12, 1936, No. 13394. Convention date, July 6, 1935. [Class 98 (i)] In apparatus for controlling the exposure in a camera, twc control devices independently set in accor. dance with the exposure time and the film sensitivity act on a floating lever to regulate the light incident on the photo electric cell, one device moving the fulcrum of the lever whilst the other device turns the lever about its fulcrum to give the same proportional alteration of light incident on the cell. A baffle 25 is mounted in front of the P.E. cell 13 and a grid 26 with a bifurcated lug 27 is raised vertically by a pin 29 on a floating bell-crank lever 30 fulcrumed at 31. The lever is rotated about its fulcrum 31 by rotation of a shaft 32, a projection 37 on the film magazine 36 displacing a crank 38 in accordance with the sensitivity of the film as described in Specification 451,685. A slot 35 on a member 35<1> integral with the shaft 32 engages a pin 34 on the arm 33 of the lever 30. The fulcrum 31 is carried on a member 39 which is moved vertically on guide pins and slots 40, 41 by a cam 24 on the speed knob 21 of the shutter 20. Any movement of the adjustment members produces proportional variation of the area of cell 13 exposed through the grid 26 and baffle 25. Alternatively instead of varying the area of exposure of the cell, the density of the light falling thereon may be varied by known means. The current in the photoelectric cell regulates the diaphragm setting of the camera as described in Specification 451,659.
