Filed: 1939-02-02
Abstract: 524,609. Tunnels &c. PENFOLD, H. L. Feb. 2, 1939, Nos. 3548 and 14274. [Class 85] In tunnels and like underground structures, lining members are employed which are shaped so as to provide channels at the transverse or longitudinal joints, or both, on assembly, and into said channels is forced a waterproof sealing medium which is initially liquid but sets into a plastic state. The lining members may be of metal. reinforced concrete, &c. The filling material may be Portland cement, mixed with a bituminous emulsion. In Fig. 3, the segments have grooves 17 between flats 15, 16, so that when the segments are bolted together, passages 21 are formed to receive the filling.; at the ends of the segments, the inner flat 16 may be tapered and if the passages 21 are to be blocked at any point, the outer flat 15 may be similarly shaped. Holes 19, Fig. 8, allow introduction of the filling and are preferably tapped to permit subsequent plugging. The outer flats 15 may have notches 20 allowing passage of the filling material to grout the space around the lining. If the filling contracts on setting, pressure may be applied to it to fill gaps, as by elongated plates 23 threaded to the bolts 22 and advanced by turning the bolts. In Fig. 9, the inner flats 16 are omitted, and before inserting the filling, the space between the segments is closed by a wood &c. packing 24 with stop blocks 25 ; the packing member is stepped at the centre and tapered at its ends. After the filling has set, the packing is removed' and the space left is caulked or sealed.

Abstract: Electrical insulation material is composed essentially of (1) an organopolysiloxane resin having from 1.4 to 1.8 organic groups per silicon atom, in which resin from 10 to 80 mol. per cent of the polymer units are dimethylsiloxane units, the remaining units being monomethyl-, monophenyl-, phenylmethyl- or diphenyl-siloxane units, with or without limited amounts of SiO2 and/or R3SiO0,5 units where each R is a methyl or phenyl radical, and (2) from 10 to 40 per cent by weight of the resin of particulated mica having an average particle size of 0.2 to 20 mils.  The mica may be mixed with the resin in any manner, but is preferably suspended in a solution of the resin in a hydrocarbon solvent such as toluene.  Curing catalysts such as sodium, potassium, lead, zinc, tin and cobalt carboxylates may be used.  Electrical equipment may be coated by dipping in the resin solution in which the mica is suspended, and the resinous coating is cured by heating up to 250 DEG  C.  Impregnation may be effected under vacuum.  In examples: (1) comparative insulation tests made on transformers coated with siloxane compositions are given; (2) glass cloth is impregnated with the siloxane resin-mica composition; zinc and cobalt octoates are employed as curing catalysts.
