Abstract: 1288516 Aromatic polyamides CELANESE CORP 23 Sept 1970 [26 Sept 1969] 45203/70 Heading C3R In a process for producing a polyamide of inherent viscosity above 1À0 (determined on 0À5 wt. per cent solution in 95% H 2 SO 4  at 25 C.) by subjecting an aromatic diamine to reaction with an aromatic diacid halide in the presence of an amine as acid acceptor the reactants and the amine are all dissolved in a solvent comprising anhydrous gamma-butyrolactone and the hydrohalide of the acid acceptor remains dissolved in the solvent. This requirement will usually be satisfied if the pK a  of the acid acceptor is at least 0À5 units greater than that of the diamine reactant. Specified compounds are:-diamines -m- and p-phenylene diamines and the 4,4<SP>1</SP>- or 3,31-diamines of diphenyl sulphone, diphenyl ether or diphenyl; acid halides-of iso- and/or tere-phthalic and the 4,41- or 3,3<SP>1</SP>-dichloroformyl derivatives of diphenyl sulphone, diphenyl ether or diphenyl; acid acceptors-2,6-dimethyl pyridine, 2,4,6-trimethyl pyridine, pyridine and triethylamine. The dissolved hydrohalide of the acid acceptor is stated to improve the solubility of the formed polymer enabling a higher inherent viscosity to be obtained. In the examples, wherein iso- and/or terephthaloyl-chloride is condensed with m- and/or p-phenylene diamine polymers of inherent viscosities ranging from 1À79 to 3À9 are attained in Examples 1 to 3 and 6 where the acid acceptor is 2,6-dimethyl pyridine but comparative Example 4 shows that the pK a  differential between pyridine and m-phenylene (0À4) is not quite sufficient for this combination (I.V. of product is 0À9) while comparative Example 5 repeats Example 1 but with triethylamine or magnesium oxide as acid acceptors. The products of the invention may be cast into films e.g. from dimethyl acetamide or formamide. Reference is made to Specification 871,578.

Abstract: 1297419 Shovelling machines CLARK EQUIPMENT CO 20 Nov 1970 [26 Jan 1970] 55195/70 Heading E1F [Also in Division B8] A front end loader has a pressurised fluid source, a valve means and a motor for actuating the boom arms, a similar system for actuating an arm-mounted load carrier, and valve means for combining fluid from the two sources, only when the carrier motor is actuated by its valve means, to actuate the carrier motor at higher speed. In the valve actuating means described the rotation of spindle 144, Fig. 6, about axis 148 of pivot 146 causes movement, Fig. 5, via links 180, 174 of spools 108, 84 of carrier-actuating valve 60 and fluidcombining valve 58. The pivot 182 of the linkage lies closer to spool 108 than to spool 84, so that spool 108 is subject to the greater force and the carrier-actuating valve 56 is actuated before fluid-combining valve. Boomactuating valve 56 is actuated independently of valves 38, 60 by movement of lever 156 to rotate sleeve 150 about shaft 144 to move valve spool 166 of valve 56 via universal joint 160. Valves 56, 58 are so connected by fluid passages that valve 58 only combines fluid when valve 56 is not actuating the boom motor.

The automatic stopping device is pre-set by estimating the amount of material, and hence the time required, to be removed from the lens by the distance 46 between the lugs 51, 52 of the frame when the lens is tried in the frame, the lens having previously been formed to shape and with the required bevel edge. The lens is then mounted between pads 16, 17 on shafts 18, 22 which are mounted in a frame 10 pivotable about a shaft 11 rotatably connected by universal couplings 25, 26 and slightly flexible shaft 27 to a worm drive 28 driven from a motor 29. Sprockets 30, 31 are connected by chains 38, 39 to sprockets 32, 33 on the shafts 18, 22 so that the lens is rotated at a slow speed, e.g. 4 r.p.m. The shaft 11 is supported by a yoke 12 from a post 13 so that the lens can move laterally as the edge engages a grinding wheel 40 which is belt driven and formed with a V-groove in its surface. The lens bears by gravity on the grinding wheel and rapid vertical movements are damped by a disc 49 carried by an arm 47 from the frame and located within a viscous liquid in a container 50. The frame is connected to a piston 52 in a cylinder 56, the lower end of which is connected by a valve 59 to a compressed air source 62 and exhaust 61. The valve is controlled by a solenoid 63 actuated by the pre-settable stopping device 60 in the form of a timer having a dial 64 which the operator sets to the time he estimates from the gap 46 between the lugs 51, 52 of the spectacle frame is required for grinding the lens until it is the correct size.
