Title: Improvements relating to the treatment of asbestos fibre to be used for forming insulating coatings
IPC: C04B20/10
Filed: 1944-07-17
Abstract: <PICT:0583077/III/1> <PICT:0583077/III/2> <PICT:0583077/III/3> <PICT:0583077/III/4> <PICT:0583077/III/5> In the formation of coatings by spraying asbestos with an adhesive, dust is eliminated by mixing the asbestos with a quantity of water or other damping material enough to coat substantially every individual particle but not so great that after coating there is free liquid which can be expelled by pressure, the mixing being so carried on that substantially every particle of asbestos is damped and also the damping material is so uniformly distributed throughout the asbestos that there is no tendency for particles to stick together by reason of differing moisture contents, and the damped asbestos is subsequently suspended in air and sprayed.  The damping material may be added to the asbestos in a mill or mixing drum, or the mixing may be effected by projecting a suspension of the asbestos and a finely-divided stream of the damping material through the air so that they travel together and the damping is effected in air.  The damping material may be added to another material (e.g., fibre, sawdust, paper pulp or a wetting agent) which is then mixed with the asbestos, or a hygroscopic material (e.g., calcium chloride or glycerine) may be evenly distributed throughout the asbestos, the mixture exposed to a moist atmosphere, and then mixed.  The mixing may be carried out in a rotary drum 1, containing a rotary brush 2 rotated by a motor 15. The rotation of the brush 2 causes the drum 1 to rotate at a speed differing from the brush so tearing apart the asbestos; this operation is assisted by the tongues 8 attached to the inside of the drum surface.  Water is fed into the drum through a nozzle 3 and damped asbestos removed through a door 17, [see Group II]. Specification 368,368 is referred to.

Title: Improvements in and relating to the manufacture of electric insulating bushings, tubes, and the like
IPC: H01B3/42
Filed: 1946-05-06
Abstract: 615,671. Coating webs. DUNTON, A. R., CARTWRIGHT, R. P., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. May 6, 1946, No. 13704. [Class 140] [Also in Group XXVIII] In the manufacture of electrical insulating bushings, tubes and the like by winding strip material on a mandrel, the strip is first impregnated with a liquid comprising a copolymerizable homogenous mixture of an allyl ester and an unsaturated alkyd resin. One such mixture consists of 66.6 per cent of dyallyl ester, 33.3 per cent of diethylene glycol maleate and .1 per cent of a catalysing agent such as benzoyl-peroxide. Fig. 1 shows an apparatus for carrying out the process, consisting of a V-shaped tank 1, which contains the liquid and which carries a fixed cylinder 2 and metal (preferably steel) blocks 6 and mandrels 3, 4. Dried paper strip 5 is fed from the mandrel 3, between the cylinder 2 and the blocks 6 on to the mandrel 4 which is rotated at a moderately low speed (e.g. 40 r.p.m.). The process is preferably carried out in a vacuum chamber. If the mandrel 4 is submerged in the impregnant this condition is unnecessary. In this latter case, the cylinder 2 may constitute the mandrel. Fig. 2 shows a modified apparatus, the cylinder 2 being hollow, perforated on its underside and connected by a pipe 9 with a vacuum pump 10. This allows the impregnant to be sucked through the strip 5 as it passes under the cylinder, and thus ensures complete impregnation. A receptacle 11 traps any impregnant carried over by the pipe 9. Fig. 2 also shows the strip being dried before entering the tank by being drawn across a smooth metal sheet guide plate 7 heated by electric heaters 8. An alternative method is to wind the strip dry and then impregnate it under pressure. In each case, the wound tube is finally heated in an oven to convert the resin to a solid state.
