Propylene is polymerized in the gaseous phase in the presence of a Ziegler catalyst system wherein purified propylene (which is suitable for achieving a catalyst activity of at least 3000 parts of polymer per part of catalyst per hour; a method of determining the catalyst activity is given in the Specification) is introduced in liquid form into the reaction zone, vaporized and polymerized therein, in the presence of a catalyst whose molar ratio of titanium compound to aluminium compound is in the range of 1: 0À5 to 1: 6. Unpolymerized monomer, on leaving the reaction zone, may be condensed and recycled with fresh monomer. Preferably the reaction is carried out at 10 to 100 atmospheres, 70 to 120‹ C., and using a catalyst comprising TiCl 3 , AlCl 3  and Al(Et) 3 . The homopolymerization of propylene is exemplified and the process is also applicable to the copolymerization of ethylene and propylene.

Abstract: 1,238,509. Feeding work to saws. KURT STOLL K.G. 29 Aug., 1968 [26 Sept., 1967], No. 41263/68. Heading B5L. [Also in Division B3] A feeding device for feeding strip or rod stock to an operation position, to be stamped, pressed, 'cut or sawn, of the reciprocating gripper type is controlled by means of valves which include at least two valve chambers and a fluid communication between them in which movement of a push rod in one chamber causes automatically the movement of a push-rod in the other. In the embodiment shown in Fig. 2 two four-way valves 11 and 16 are linked by a fluid passage 15. A cam 30 associated with a machine tool causes the switch 10 to close activating an electromagnetic valve 33 causing the pushrod of valve 11 to be shifted in the direction 12. Working fluid now flows from line 13a through channel 13b to line 13c and line 15. Line 13c connects to 13d for actuating the reciprocating gripper. Pressure in line 15 causes the push-rod of valve 16 to move in direction 12 linking working fluid in line 18a via channel 18b to line 18c and inlet 18d for a double-acting cylinder which reciprocates the gripper. At the same time inlet 19a of the double-acting cylinder is connected to exhaust 19e via channel 19c of valve 16 and inlet 14a of a stationary gripper is connected to exhaust 14e via channel 14c of valve 11. Thus stock is fed by the feeder. When the cam 30 on further rotation opens switch 10 valve 33 becomes inoperative and pressure fluid in line 20 causes the push rod of valve 11 to move in direction 21. This opens lines 13c and 15 to exhaust 14e via channel 14f. The release of pressure from line 15 causes the push-rod of valve 16 under the action of pressure fluid in line 21a to move in direction 21. Thus the stationary gripper grips the stock, the reciprocating gripper is released and moved back to its initial position.

Abstract: 1297117 Control of DC motors ELLIOT BROS (LONDON) Ltd 16 Dec 1969 [18 Dec 1968] 60128/68 Heading H2J [Also in Division H1] A mechanical drive transmission system, suitable for inching an electric motor drive, for example, comprises an input member driven via a first friction clutch, an output member coupled thereto via a second friction clutch, the input member having stop-limited movement from a datum position in either of two directions against spring bias, and control means whereby the clutches may be engaged to provide limited movement of the output member and disengaged to allow spring return of the input member to its datum position. As shown, motor 13 drives a 180 degree limitation device 21 via reduction gearing 15 and clutch 23 and output is taken via clutch 25 and reduction gearing 17. The device 21 actuates a switch 51 or 53 (according to the direction of rotation) after it has been driven 180 degrees against the bias of a torsion spring (see Division H1). The control is by a double-pole change-over switch 67 (Fig. 4) which is spring-urged to a central off position and energizes motor 13 and clutch windings 23<SP>1</SP> and 251 when manually operated for forward or reverse running. When either switch 51 or 53 is opened the motor 13 stops and clutch 25 is disengaged, but clutch 23 remains energized and prevents the return of device 21 to its datum position. When switch 67 is released clutch 23 frees the device 21 which is then restored by its torsion spring in readiness for a further incremental drive. A brake 63 may be provided to hold the output shaft of clutch 25 when the latter is disengaged.
