Title: Production of liquid olefine polymers
Inventor: JACKSON WILLIAM KENYON
IPC: C08F240/00
Filed: 1959-10-30
Abstract: Olefine polymers of molecular weight 450 to 1,500, and consisting predominantly of polyisobutylene are made by continuously feeding a gas consisting essentially of C1 to C5 hydrocarbons which contain at least 30% by weight of isobutylene, under a pressure at which it is liquefied and at a temperature not lower than - 43 DEG  C., to the input end of a reaction zone together with a suspension of aluminium chloride of particle size of 40 to 200 (United States Standard Mesh), removing the total reaction mixture from the output end of the reaction zone, separating the mixture into a recycle portion amounting to at least four times the weight of fresh liquefied feed gas entering the reaction zone in the same time, and a product recovery portion, recycling the recycle portion to the input end of the reaction zone and diluting the fresh feed therewith and recovering polyisobutylene from the product recovery portion.  The aluminium chloride catalyst is generally promoted with hydrochloric acid, which may be added directly to the polymerization system or formed therein, e.g. by introducing into the system small amounts of water vapour or chloroform.  The catalyst is generally introduced into the system in polyisobutylene, and is preferably present in the system in an amount of 10 to 20% by weight of the hydrocarbon.  The polymerization is usually effected in a vertical reaction zone, of substantially constant cross-sectional area, which is surmounted by a settling zone of much larger cross-sectional area, the recycle portion being withdrawn at a level such that it contains substantially all the separated still active catalyst, and the recovery portion, substantially free from the catalyst being withdrawn at a higher level.  Two flow diagrams are given of preferred apparatus arrangements for carrying the process into effect.

Oleic acid and/or triethanolamine may be added to the slip to reduce its viscosity and ethyl cellulose to increase the green strength.  The mould releasing agent may be milled flake graphite which is applied to the mould as a suspension in xylene.

Title: Process of removing chlorine or hypochlorite compounds from water
IPC: C02F1/76
Filed: 1929-12-03
Abstract: Water is dechlorinated by bringing it into intimate contact with lignin or non-hydrophobic lignin-containing substances such as wood, which are otherwise of such a character that the lignin present therein can combine with the chlorine contained in the water.  The water is filtered through or agitated with the dechlorinating agent. The wood employed may be sterilized by steaming, may be wholly or partly freed from resin, and may be in the form of shavings or sawdust.  The lignin-containing substances, e.g. sawdust, may be moulded into briquettes with or without a binding agent.  The lignin chloride formed may be removed from the water by filtering through, or agitating with, substances having an adsorptive action such as active carbon or silica, or Fullers earth, or carbon in various forms such as coke, or lignite or coal which has been wholly or partially deprived of humus compounds and bitumen.

Title: An improved forging manipulator
IPC: B21J13/10
Filed: 1965-09-01
Abstract: 1,121,392. Forging manipulators. HYDRAULIK G.m.b.H. 1 Sept., 1965 [1 Sept., 1964], No. 37333/65. Heading B3H. A forging manipulator has a stepwise movement of its peel 1 produced by drive means 21a, 21b which serve to hold the peel stationary during forging. The peel 1 is suspended by pivoted rods 3 from adjustment levers 4 mounted on trestles 6 of the manipulation carriage 7 which runs on wheels 8 along rails 9. The manipulator is driven by an hydraulic motor 73 through gearing 74, 24 engaging with a rack or chain 25 embedded in the ground; motor 73 is controlled by a slide valve 70 supplied with hydraulic fluid from source 10. The manipulator moves continuously but with variable speed. Longitudinal stepwise movement of the peel 1 relatively to the carriage 7 is effected by opposed hydraulic cylinders 21a, 21b engaging a plate 5 of the peel and movable over relatively stationary pistons 20a, 20b mounted on the carriage 7. Pressure liquid is distributed to the cylinders 21a, 21b through distributing slide valve 60, 61 from the source 10. The reaction thrust on the pistons is transmitted through the supply pipes 22a, 22b to a power unit 22, then acting as a rotary hydraulic motor, coupled through a disconnectable gear 23 with the driving gear 24, which thus transmits the reaction to the rack or chain 25. This causes the carriage to move at a speed equal and opposite to that of the peel and thus the latter remains stationary relatively to the ground. An endless chain 32 passing around sprockets 30, 31 is driven from the gear 24 so that its upper strand also remains stationary relatively to the ground. The extent of longitudinal movement of the peel is determined by a carriage 40 connected to the piston rods 62, 72 of the distributing valves 60, 70. Carriage 40 has a sprocket (43), Fig. 3 (not shown) engaging in the upper strand of chain 32 and driven by a rotary hydraulic motor (41) under control of a spring- loaded slide valve (44-46). Sprocket (43) also supports a disc (50) carrying radial plungers such as (51), Fig. 4 (not shown), with roller followers (52) for actuating the valve stem (44). Plungers (51) are biased inwardly by springs (53) and can be withdrawn outwardly by lifters (54) and there held by pivoted detents (55). The lifters (54) and detents (55) are controlled by 'electrical signals received from the forging press control mechanism which selects the particular plunger (51) to the actuated and hence the required step. Rotation of the jaws 11 within the peel is controlled by an hydraulically operated stepping mechanism, Fig. 5 (not shown), controlled by signals received from the press. The manipulator may alternatively be operated mechanically or electrically.
