Title: A plastic material made from caseine
Filed: 1921-05-30
Abstract: Casein is prepared for use as a plastic material by dissolving it in a solution of sodium or potassium carbonate, sodium silicate, borax, or ammonia, adding colouring-matter to the solution if desired, and precipitating the casein with the reagent described below.  The precipitate is worked up by heat into the desired forms and hardened with formaldehyde.  The precipitating-agent is made by dissolving zinc sulphite, potassium or sodium meta-bisulphite, glacial acetic acid, and alcohol in water, adding zinc cuttings, decanting the clear liquor, treating this with milk of lime, and filtering.

Abstract: 918,580. Filters. COAL INDUSTRY (PATENTS) Ltd. June 19, 1959 [May 12, 1958], No. 15158/58. Class 46. Coal-washery slime is pumped (30) from tank 28 to a thickening filter 11 at a pressure of e.g. 60 lbs. per sq. inch, some of the feed passing into a surge tank 35 containing compressed air, the air being further compressed thereby. Filtrate from elements 12 flows into a header tank 17, whence it is discharged by the side overflow pipe shown. Periodically and automatically valve 33 is closed, and a valve 40, linked to it, is opened, permitting backflushing from tank 17, after which the cake deposited in the bottom of tank 11 is stirred (19) to form thicker slurry. During this period pump 30 continues to feed slime into surge tank 35. At the end of the backflushing period valve 40 first closes, and shortly afterwards valve 33 opens. Thereafter, slime for filtration is supplied to filter 11 both by pump 30 and by surge tank 35, the pressure build-up in the filter being more rapid than would be the case if the pump alone was used. Lime circulated by a pump 42 between tanks 41 and 46 may be added to the feed tank 28 through a valve 49 to improve the filtration characteristics of the slime. The filter elements 12 may be frusto-conical. Alternatively each element may consist of two pipes 69, Figs. 6 and 7, and two perforated plates 65, around which assembly a sleeve of nylon cloth on coconut matting may be fitted.

Abstract: 1467671 Making electrical connections K LOEPFE AUTOMATION AG 8 April 1974 [17 April 1973] 15499/74 Headings B3A and B3Q [Also in Division H2] A terminal is crimped to a wire in apparatus having a terminal feeder, crimping members and means for ejecting the crimped connection. The press is operated pneumatically or hydraulically and includes means for stripping insulation from the wire. Press actuation from a cylinder 5 is by toggle links 11, 12 one (12) of which is connected to an upper tool-slide 29 and the other (11), through a top member 17 and rods 21 is connected to an oppositely-moving lower tool-slide 41. The upper slide 29 slides on the rods which are adjustable in the top member 17 for varying the stroke, adjustment being by threading gears along worms on the ends of the rods. Dieholders 31, 42 are fixed to the slides by single screws 37, 44, and the rods 21 are mounted in guides 23 fixed to a vertical plate 1. Operation of the cylinder is caused by a pneumatic switch at the end of an insulator stripping operation, as described below. Work-holders; ejecting.-Wire is inserted through a slot 84 in the plate 1 up to a stop 80, Fig. 4 which stops the wire-feed and operates insulation-severing knives, as described below. The wire is clamped in the mouth of an ejector 108, Fig. 6, by a clamp 142 which is released by retraction of a piston-rod 149 so that it may be turned about a pivot 144 by springs 148, 152 in order to apply the clamping pressure. A pawl 112 pivoted on a lever 121 engages the side of the ejector 108 the top of which is engaged by a latch 136. Abutments 126, 130 mounted on the top slide 29 co-operate with the lever 121 and latch 136 so that after a crimping operation abutment 130 releases latch 136 from ejector 108 which is turned anti-clockwise by spring 152 pulling on lever 121 released by movement of abutment 124. Simultaneously operation of cylinder 140 pivots the clamp 142 out of the slot 84 from which the connection is ejected by continued movement of the ejector 108. Insulation is stripped by knives 74, Fig. 4, on holders 72, 86 which are carried by a cylinder 64 and a piston-rod 68. The cylinder is mounted transversely on another cylinder 56 the pistonrod 62 of which is fixed to one of the rods 21, so that after the wire has been gripped between the clamp 142 and ejector 108 and the insulation has been severed by operation of the cylinder 64, movement of the cylinder 56 along its piston rod 62, which is triggered by a pneumatic switch, carries the closed knives along the wire for stripping the insulation. Feed for the strip of connectors through a guide 48, Fig. 3, on the lower tool-slide 41 is by a spring 102 on a slide 96 having spaced abutments 98, 100 which are engaged by a finger on a part 70 movable by the cylinder 56.
