Abstract: 711,173. Sorting screw-stoppers. TWEDDELL, J. A., and LAYLAND, W. April 21, 1953 [Jan. 22, 1952], No. 1741/52. Class 117 [Also in Group XVII] Screw-threaded headed stoppers are delivered by an intermittently actuated conveyer 16 and an inclined plate 17 to a continuously rotated helical conveyer 2, the direction of rotation being in the direction of the arrow 5 and correctly orientated stoppers being suspended by their heads between the groove 2a of the conveyer and a conveyer bar 4 at one side, the top edge of which is in the same horizontal plane as the axis of the helical conveyer. Incorrectly positioned stoppers are either joggled into correct position by resilient members 12 or are carried over the top of the conveyer to fall into a hopper 1. The last resilient member 12a is inclined towards the conveyer to ensure that any. incorrectly positioned stopper must pass into the hopper 1. The stoppers are finally supported .by a circular groove 2b which forms the end of the helical groove 2a and a groove 6a in a roller 6. This roller is moved intermittently to and from the conveyer to allow the stoppers  to drop into a feed tube 10 leading to the stoppering machine. Undersize stoppers fall between the conveyer and the bar 4 into the hopper 1. Oversize or chisel-headed stoppers are intercepted by an L-shaped resiliently mounted plate 14 which ensures that they will be carried over the helical conveyer into the hopper 1.

Patent GB-594716-A (GB)
Title: Improvements in or relating to processes of making oils having improved drying properties, and the improved drying oils resulting therefrom
Filed: 1945-01-30
Abstract: Oils having improved drying properties are made by polymerizing diene and polyeneunsaturated higher fatty acids and adding a substantial quantity, e.g., 5 per cent. to 50 per cent. by weight, of the polymerized fatty acids to a drying or semi-drying oil, p  heating the two together for a period of time and at a temperature sufficient to enable the polymerized fatty acids to displace mono-unsaturated fatty acids from the oil, and then removing the liberated monomeric acids to produce an oil having improved drying properties.  The polymerized fatty acids may be dimers and they may be obtained by splitting an oil containing diene and polyene triglycerides, recovering the fatty acids and heating the recovered acids at an elevated temperature and for a period of time sufficient to effect their polymerization. Alternatively, the polymerized fatty acids may be obtained by heating an oil containing diene and polyene triglycerides for a period of time and at a temperature sufficiently high to polymerize these compounds, then splitting the oil and recovering the polymerized diene and polyene-unsaturated fatty acids. The oil whose drying properties are to be improved may be heated with the acids at a temperature of from about 250 DEG  C. to 350 DEG  C., the time and temperature being insufficient to cause the oil to gel. The diene and polyeneunsaturated higher fatty acids may be derived from linseed oil and the oil whose drying properties are to be improved may be soya bean oil or linseed oil. Alternatively, the polymerized fatty acids may be prepared from sardine oil and used to improve the drying properties of soya bean oil.  In an example, 96 parts of linseed oil fatty acids are polymerized for seven hours at 300 DEG  C. in an atmosphere of carbon dioxide and then distilled at an absolute pressure of 10 m.m. mercury to remove 43 parts of non-polymerized acids.  To the 53 parts of the viscous residue are added 212 parts of alkali refined linseed oil and the mass heated to 300 DEG  C. in an atmosphere of carbon dioxide and held at that temperature for one hour and 50 minutes.  The pressure is then reduced until nearly all the uncombined fatty acids are removed, leaving a light coloured residue having a viscosity of 47.0 poises at 25 DEG  C. and an acid number of 21-2.
