Title: Improvements in and relating to power-operated machine guns
IPC: F41B11/00
Filed: 1919-02-14
Abstract: 142,932. Sneed, W. M. Feb. 14, 1919. Machine guns. - Comprises a power-driven pneumatic machine gun wherein the projectiles are propelled by the exhaust gas from an explosion motor which actuates the feed mechanism of the gun and also drives a mechanism for imparting an automatic reciprocating lateral traverse to the gun during firing. Fig. 3 is a longitudinal vertical section of the gun. The motor 35 rotates a vertical shaft 18, cranks 32, 33 on which operate longitudinal rods 30, 31, and thereby regulate the supply of projectiles 38 from the hopper 37 to the bore of the barrel 16. At its lower end, the shaft 18 is connected to a worm shaft 21 which drives a worm-wheel 27. An eccentric projection 26 on the worm-wheel engages a slot 25 in the lower plate 12' of the gun casing, and imparts a lateral reciprocating motion to the gun about the vertical pivot 29. The exhaust gas from the motor passes by a pipe 41 to the chamber of the gun, and expels the projectile 38 in the bore.

Abstract: 395,058. Sawing planks from billets. BROWN, R., Royston Mill, Rubicon, Victoria, Australia. Feb. 8, 1932, No. 3730. [Class 145 (ii).] Feed motions.-A saw-mill. in which the work is repeatedly fed past the saw so as to cut off a number of boards, has a return feed for the work after it has been cut, and means for guiding the work from the return feed on to the forward feed again. The billet B, Fig. 3, is fed to the saw S, which may be a circular saw or band saw, by an endless chain conveyer 9, the billet being held against a fence 7 by spring members 16. The slat being cut off is held against the saw by spring members 25, and when severed is deflected from the machine by a member 28 to which it is fed by the following billet. The remainder of the billet is deflected by a member 29 and after inspection is placed by the operator on the return feed 8, being held against a fence 8a by springs 17. The billet is guided by spring arms 19, 20 carried by the fence 8a on to the forward feed 9 to be returned to the saw. A vertical roller 18 supports the outer face of the billet during this transference. The return feed 8 comprises an endless chain to which are pivoted L-shaped arms 22 ; their free ends 22a are guided in a groove in the member 15 which carries the spring arms 16, 17 and roller 18, the latter being grooved to permit their passage ; the short limbs of the arms 22 are in contact with a guide-plate 23, Fig. 4, which is interrupted at 23a to allow the arms 22 to clear the deflected billet. The return feed is driven at a greater speed than the forward feed, to recover time spent in inspection of the billet.

Title: Improvements in or relating to the purification of polymers contaminated by metal compounds
IPC: C08F6/02
Filed: 1960-02-08
Abstract: Polymers of unsaturated monomers, e.g. polyethylene or polypropylene, are purified by treating the dry polymer with dry hydrogen chloride, in the presence or absence of organic solvents or diluents and under such conditions that there is a complete or substantially complete absence of liquid water and water vapour, and then with water.  The polymer may also be treated with an alcohol, e.g. ethanol or butanol-2, before, during, and/or after the hydrochloric acid treatment, and oxygen or an oxygen-containing gas before or during the hydrochloric acid treatment.  After the polymer has been water-washed, it may be treated with a solution of a compound which forms soluble complexes with one or more of the metals, which are to be removed from the polymer.  The treatment with the complexing agent may be effected in the presence of a wetting agent and also simultaneously with steamstripping.  The impurities removed are metallic catalyst residues formed from "Ziegler-type" catalysts. The washing water may be acid or alkaline.  The process may be effected continuously.  Complex-forming agents mentioned are oxalic acid, citric acid, tartaric acid, acetylacetone, and sodium hexa metaphosphate.
