Abstract: 501,850. Cables. STANDARD TELEPHONES & CABLES, Ltd. (Sonnenfeld, H.) Sept. 17, 1937, No. 25293. [Class 36] In a cable system of the kind comprising one or more insulated conductors installed in a rigid pipe filled with gas under pressure, the insulated conductor or conductors is or are surrounded, prior to installation in the pipe, by an expansible sheath which, after the drawing of the sheathed conductor or conductors into the pipe, is expanded into contact with the inner wall of the pipe, so as to form a lining therefor, by applying gas pressure to the interior of the cable. The sheath may be of elastic material such as rubber or the like, or suitably plasticized polystyrene ; or relatively inelastic materials, such as lead or cellulose esters, may be used, in which case the sheath is formed with a corrugated or folded cross section so that expansion may be effected without stretching the sheath by the. opening out of the folds or corrugations. The Figure shows such an unexpanded sheath 3 surrounding an insulated conductor 1 installed in a pipe 4. The insulated conductor or conductors may be closely surrounded by an extruded layer which separates the insulation from the gas filling the pipe, the expansible sheath being applied over the extruded layer and expanded by gas introduced under pressure in spaces between them. When the sheath is formed of a material which is a poor conductor of heat, longitudinally extending and circumferentially spaced heat conducting elements may be embedded in the sheath. A corrugated tubular electric conductor may be embedded in the sheath to enable the cable to be used for the transmission of high-frequency currents. To prevent damage to the sheath during the drawing of the cable into the pipe the outer surface of the sheath may be ribbed, whilst to facilitate drawing-in, a lubricating layer, such as a layer of soap or graphite, may be provided on the sheath. Specifications 488,069 ; and 490,814, [Group IV], are referred to.

Title: Improvements relating to fluid pressure braking systems
IPC: B60T13/62
Filed: 1948-10-01
Abstract: 645,550. Automatic fluid pressure brake system. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., SIMMONS, A. W., and CADMAN, N. G. Oct. 1, 1948, No. 25590. [Class 103 (i)] In an automatic fluid pressure brake system for a vehicle, the emergency actuation of the brake cylinder is carried out by fluid from a standby supply through a valve means that compares the actual brake pipe pressure with that obtaining in some part other than the auxiliary reservoir, this arrangement avoiding the defects of the known systems in which the emergency actuation depends on the rate of fall of pressure in the brake pipe. As shown in Fig. 1, there is the usual brake pipe 1, auxiliary reservoir 19, and triple valve 3 connected to the brake cylinder 6, but the latter is also connected by pipe 7 to a chamber 13 below a spring-loaded piston 14 that operates a valve 11, 12 at the base of the valve device 17. The chamber 16, above piston 14, is connected by pipe 18 to the brake pipe 1, and the valve device 17 is also connected through a limiting valve 10 and a non-return valve 9 to a main reservoir pipe 8. The valve 11, 12 is normally closed but should the pressure in the brake pipe 1 above piston 14 fall below a certain minimum value, the piston 14 is moved upwards and main reservoir air flows from pipe 8 into the brake cylinder to give an emergency application of the brakes. The limiting valve 10 prevents the brake cylinder pressure being built up from the main reservoir pipe to a value so high that the valve 11, 12 cannot be reclosed by the brake pipe pressure acting on piston 14. The non-return check valve 9 prevents loss of air should the pipe 8 be broken. Modifications are described in which there is a supplementary reservoir adjacent to each valve device 17, charged either from the main reservoir pipe, or from the brake pipe itself through a check valve. As shown in Fig. 5, the valve device 17 comprises a slide valve that controls the flow from the supplementary reservoir 23 to the brake cylinder 6 through the limiting valve 10, in dependence on the brake pipe and main reservoir pressures acting above and below piston 14.
