Abstract: 1,130,987. Vinyl chloride. KNAPSACK A.G. 9 Feb., 1967 [8 March, 1966], No. 6162/67. Heading C2C. Vinyl chloride, obtained by the addition of HCl to acetylene, is worked up by: (a) introducing crude, predried and gaseous vinyl chloride at 3 to 10 atmospheres gauge and 15‹ to 90‹ C. into a first distillation column, (b) distilling this so that the bulk of the vinyl chloride-containing distillate is condensed and returned to the sump, and the ,uncondensed matter is scrubbed under pressure with a liquid chlorinated hydrocarbon to give a head gas free from vinyl chloride and a vinyl chloridecontaining scrubbing solution as a sump product, (c) distilling the sump product from the first distillation in a second column under a lower pressure as long as the concentration of higher-chlorinated C 2 -hydrocarbons in the sump product is not more than 40% by weight to give a distillate of pure vinyl chloride, (d) distilling the sump product from the second distillation together with the scrubbing solution from the scrubbing column in a third column at or above atmospheric pressure to give a head product containing vinyl chloride which is combined with fresh uncompressed crude vinyl chloride and passed to the first distillation stage, (e) refluxing the sump product from the third distillation stage as the scrubbing liquid to the scrubbing column, and (f) separating into two partial streams the gaseous effluent from the first distillation, using one of these streams as a diluent for acetylene in the production of vinyl chloride and scrubbing the second stream in a scrubbing column under a pressure between 5 and 6 atmospheres gauge and at a temperature between 10‹ and 25‹ C.

Abstract: 872,055. Fuel injection pumps. BESSIERE, P. E. Sept. 17, 1957 [Jan. 3, 1957], No. 6364/61. Divided out of 861,754. Class 102(1). A fuel injection pump comprises a main piston 2 which on its upward stroke first supplies fuel past a non-return valve E to act on a slide valve 12 to close a conduit 9, and then delivers fuel past non-return valve 11 to a chamber 7a to actuate a piston 5 which delivers fuel from a chamber 7b to the pump outlet 15. The fuel is fed to chamber 7b through conduit 36, which provides from the feed pipe 4 for the main piston. The piston 5 moves against a spring loading 6 until a bypass conduit 17 is opened. The return of the slide valve 12 during the suction stroke of piston 2 is controlled by a throttle H, as described in Specification 872,053, the groove 12b of the valve providing an increasing throttled passage as the valve opens conduit 9 and when the valve is stopped by its abutment 20 the groove provides a constant throttle 8 for the conduit 9. The time taken for the piston 5 to reach the lower position is constant and when the speed of the mainpiston 2 exceeds this value the piston 5 is actuated to deliver fuel before it has reached its rest position thus reducing the quantity of fuel delivered.

The lugs are sufficiently resilient to clamp the parts together without a blade. The lugs 8 are pressed out of a central longitudinal channel 5 which is made thinner than the parts 6 in which the guard teeth are formed. The guard teeth, which are curved and taper towards their tips, have surface grooves 7 communicating with the channel 5 to provide for water circulation and reduce the area in contact with the skin. The clamping plate 3 also has a longitudinal channel so that the blade is clamped.only near its edges. The handle 1 is pivoted to an extension 2 of the clamping plate 3. To facilitate the longitudinal separating movement, the guard-plate has concave thumbfitting end flanges 14 at each side of it.
