Title: Automatic train-stop
IPC: B60T7/18
Filed: 1920-07-10
Abstract: 148,790. National Safety Appliance Co., (Assignees of Folker, H. S.). June 23, 1917, [Convention date]. Fluid-pressure.-Valve mechanism for venting and at the same time cutting off the supply to the train-pipe of fluid-pressure brakes particularly for use in automatic train-stopping apparatus comprises a piston 30 normally subject on its lower face to main reservoir pressure through connexions 50, 52, 53 constricted at 51 and on its upper face to the train-pipe pressure through the pipe 70 leading from the engineer's valve, and chambers 17, 18 whereby the piston is maintained in the position shown in which it holds open the valve 14 and seats against a valve 24 on the stem 21 of the valve 14. In this position, air feeds to the train-pipe 15 by the passage 15<1> from the chamber 18. In effecting an application of the brakes, the chamber 54 is vented by an electri. cally actuated or other pilot valve through the passage 53 and pipe 56 whereupon the piston 30 is moved downwards, permitting a spring 32 to seat the valve 14 to cut off the supply of air to the train-pipe and unseat the valve 24 so that the train-pipe vents through passages 42, 44 in the piston and a port 33 in the casing 11. A screwed stud 80 enables the piston to be returned to the normal position should the supply of pressure air to the chamber 54 become stopped. The hand-wheel of this stud is rendered inoperative by a seal. The piston comprises a spool-shaped part 35 fitted on to a piece 37 and a head 39 screwed on the shank 38 of the piece 37. By substituting a piston having ports 42, 44 of larger capacity, the mechanism may be adapted to give an emergency application of the brakes instead of a service application as is effected with ports of the size shown. A groove 45 ensures communication between the ports 44. The casing 11 has removable end parts 71, 76 to permit ready access to the valves and piston.

Title: Improvements in or relating to wrapped electrical connections
Inventor: FAIRWEATHER ALAN
IPC: H01R4/14
Filed: 1958-06-27
Abstract: 915,552. Direct connections between conductors. POSTMASTER GENERAL. June 17, 1959 [June 27, 1958], No. 20718/58. Class 38 (1). The face of a tag or binding post 2 engaged by a component wire 3 is formed with transverse serrations 5 of which the peaks bite into the wire 3 when the wrapping wire 1 is bound round under suitable tension. The serrations penetrate any film of tarnish between the wire and the binding-post and may be disposed obliquely, Fig. 4. In Fig. 5, the serrated face is in the form of a V and the grooving of the tag face facilitates the location of the wire 3. The diameter of the wrapping wire is chosen such that its pitch coincides with the serrations. When this is not desirable, the tag or post is made so that the serrations do not intersect the edges and a wrapping wire of light gauge may be used, Fig. 6 (not shown). The terminal tag shown in Fig. 7 may be manufactured from a piece of circular cross-section stock tapped to form an internal screw-thread. A portion of the material is then machined away to provide a semi-circular cross-section tag for receiving the component wire 3 which is bound by wire 1. To avoid rotation of the component wire inside the wrapping wire, the tag may have a longitudinal groove together with serrations which are oblique or of chevron form. In Fig. 8, the tag itself is not serrated but an additional element 7 is.

Cables, suspending.-Relates to means for supporting and tensioning the overhead wires of an electric railway, and consists of a simplified arrangement of the supporting cables and of the means for carrying them from the posts or standards. Fig. 2 shows an adjustment section between successive pairs of standards a<1>, a<2> in which live wires d<1>, d<2>, entering from adjacent sections, are tensioned to take up the variations of length caused by variations of temperature. The supporting cable e<2>, which carries the live wire d<2>, is secured by an insulator to a yoke c<2> carried by the standards a<2> .The supporting cable e<1>, entering the section from the other end, is suspended by a cross cable f<1> from the standards a<1>, and it extends to the yoke c<2> to which it is secured by an insulator. The two halves of the cable e<1> between the standards a<1>, a<2> are, however, electrically isolated from one another by an insulator n. The live wire d', when it enters the section, is supported by the cable e', but after passing the middle of the section it is no longer supported. It then rises and is attached to an insulator and a, counterweight g<2> carried by a yoke b<2>. The cable d<2> is similarly carried for half its length by the other half of the cable e<1>, and it also rises, after the middle of the section, and is connected to an insulator and counterweight g<1> carried by a yoke b<1>. By this means, the bending strain on the standards, due to the unbalanced pull by the cable, is diminished.
