Patent GB-732823-A (GB)
Title: Improvements in synthetic resinous compositions
IPC: C08L67/06
Filed: 1953-11-23
Abstract: A polymerizable composition comprises (1) dipropylene glycol maleate of molecular weight 2000 to 4000; (2) propylene glycol adipate molecular weight 8000 to 10,000; and (3) sufficient styrene, usually 30 to 60 per cent, to form a solution.  A minor amount, e.g. from 5 to 15 per cent based on (2), of a vinyl chloridevinyl acetate copolymer is preferably included.  The dipropylene glycol used in the manufacture of (1) may be replaced by up to about 10 per cent of tetrafurfuryl alcohol as chain stopper and quinone may be included in the resins as inhibitor.  A filler, e.g. from 10 to to 35 per cent of finely-divided mica, or pigments such as lamp black, light chrome yellow and titanium dioxide may also be included.  When cured, e.g. with t-butyl perbenzoate, products are obtained which have good electrical resistance at high humidity and over a wide temperature range and are thus suitable for encapsulating electrical coils such as those of transformers (see Group XXXV).

Abstract: 1437627 Reels MULTI-STROKE HANDBRAKE CONTROLS Ltd 2 July 1974 [10 July 1973] 32799/73 Heading B8M part A [Also in Division F2] A cable drum, which is rotatable by a ("stroking") lever-operated ratchet, is made by fusing together two sintered components one of which forms a ratchet wheel and the other of which combines a side plate and core section. The drum 1 shown, comprising a ratchet wheel 2, is rotatably mounted on an axle 3 extending between a back-plate 4 and a cover-plate 5 secured thereto. A portion 9 of operating lever 8 is freely pivotable on axle 3 and a spring- washer 10 presses the drum towards the backplate and against lever 9 and provides a braking torque operative on the drum. A stud 6 provides a bearing for a spring-loaded holding pawl 13 and an application pawl 15 pivotally mounted on lever 8 is pressed into engagement with ratchet wheel 2 by a spring 16. Movement of lever 8 in the "freewheeling" direction is limited by interengagement of pawls 13 and 15 at faces A and B, C and D which relieves both pawls from the wheel 2 (and hence relieves cable tension). The drum is formed by sintered components 40 and 41 fused together and providing ratchet wheel 2 and combined side plate 42 and core 43 a spigot portion 44 of which fits in an aperture 45. Portion 44 is cut away in alignment with the inner edge of a chordal groove 46 wherein the end of the cable is anchored by a grub-screw (not shown).
