Abstract: 961,233. Pipe couplings. J. S. & F. FOLKARD Ltd. Oct. 29, 1962 [Dec. 19, 1961], No. 45486/61. Heading F2G. A detachable joint between pipe members includes a socket sleeve on a first member, a socket engaging spigot on the second member, the spigot having a flange composed of a split ring keyed to the spigot and an associated clamping ring, and a spigot encircling union member detachably connected with the socket sleeve and incorporating an abutment surface which exerts axial pressure on the clamping ring so as to cause the latter to close the split ring on the socket and so as to maintan the spigot firmly home in the socket. The flange is formed on the pipe end or spigot 1 by fitting over it the two halves of a split ring 12 of which the outer periphery tapers outwards towards the end of the spigot and the inner periphery is ribbed to correspond with grooves 11 cut in the outer periphery of the spigot, and by fitting over the ring 12 a complete ring 14 of complementary inner tapes and with an outside diameter approximating to the inside diameter of the mouth 5 of the socket 3. In the embodiment shown in Fig. 1, the socket 3 has an external screw thread on to which the union member 8 is adapted to be screwed and its abutment surface, which is the end of an inturned and returned rim 9 slidable on the spigot 1, presses against the end of the flange through the intermediary of a flexible sealing ring 15 and a washer 16. The flange may alternatively be formed of a single split ring of a trapezium cross-section with the base of the trapezium ribbed to fit grooves in the spigot and the annular shoulder corresponding to 6 suitably tapered, as is the abutting end of the sealing ring corresponding to 15, the two halves of the split ring being held together by a retaining ring which fits in a suitable groove. In the embodiment shown in Fig. 5 the socket 3 has a flange 21 and the union member is adapted to be tightened against by having a corresponding flange 22 which is bolted to the socket flange. Fig. 5 also shows an alternative sealing device in which inner and outer axially displaced 0-rings are carried in grooves in a ring which is composed of two parts screwed together. In the embodiment shown in Fig. 6, tolerance variations in the diameter of the pipe 25 are provided for by giving an inward taper 30 to part of the internal surface of the mouth 29 of the socket 27. A clamping ring 37 which retains the two halves of a split ring 34, forming the flange, is tapered to co-operate with the surface 30, so keying together the rings 34, 37. The split ring 34 has an annular recess 36 for a rib 38 on the clamping ring 37. The end of the pipe 25 is countersunk to correspond with a sloping shoulder 32 in the socket.

Abstract: 1,242,897. Protective arrangements. SOC. GENERALE DE CONSTRUCTIONS ELECTRIQUES ET MECANIQUES ALSTHOM. 30 Sept., 1968 [29 Sept., 1967], No. 46397/68. Heading H2K. [Also in Division G1] To detect a transition in a superconductive coil from the superconducting to the resistive state so that the supply to the coil may be broken an auxiliary coil 1 is wound with the superconductive coil 2 so that the flux linking the two coils, and hence the reactive volt drops in them, are equal or at least proportional to one another, and the difference between the voltages across the two coils determined. This difference is proportional to the resistive volt drop in the superconducting coil, which may be many orders of magnitude smaller than the reactive volt drop. The two coils are connected together at the high voltage end A and at the other end are connected to a difference amplifier 4. The output of the amplifier 4 is compared in apparatus 10 with a voltage proportional to the current in the superconducting coil to provide a signal proportional to the resistance of the latter and this signal is used to open switch 7.

Abstract: 1,046,800. Shock-absorbers. MIDLANDROSS CORPORATION. Nov. 26, 1963 [Nov. 30, 1962], No. 46662/63. Heading F2S. [Also in Division B7] A hydraulic, pneumatic and spring buffer, or combined buffer and drawgear for railway vehicles which may be fitted into a draft gear pocket or into a sliding sill, comprises a rod 7 and piston 14 slidable in a cylinder 12, an extension 15 to the cylinder 12 welded at 16 to a flange 10 bolted to a housing 11, a cylinder head 18 abutting lugs 22 on the housing and supporting the cylinder 12 and a metering tube 25 open at both ends, a liquid space 42 between the rod 7 and the cylinders 12, 15, and a liquid reservoir 64 which also contains air. The piston rod 7, Fig. 4, not shown, is undercut to provide shoulders to position a seal 31 comprising rings 35, 36, 37, 39, 40 sandwiching by spring force a resilient ring 38 squeezed against the inner surface of the extension 15, and liquid leaking past the ring 35 is ducted to chamber 26 via radial holes 45, 46 and a ball 49 trapped by a pin 51. The bolted piston head 54, Fig. 3, not shown, mounts a flange 56 retaining a valve washer 58 controlling a passage 59. The piston rod mounts a valve washer 62 which at one stage of operation restricts fluid flow from the space 42 into the chamber 26. In operation when the recoil-less gear is compressed from the Fig. 1 position, liquid is forced through the tube 25 via holes in the boss 23 to the reservoir 64, and some liquid is forced into the chamber 26 and into passage 42 via valve 62. The space 42 however is rapidly increased in volume as the piston moves forwards, compare Figs. 2 and 3, not shown, and eventually the piston abuts the head 18. On the return stroke the piston moves away from the head 18, and liquid fills the space forward of the piston flowing mainly past the valve 58. Pressure then increases in the space 42 as the piston moves rearwardly, and liquid is metered from the space 42 into duct 59 via a small clearance of the washer 62 with the cylinder 12 and through grooves 67, Fig. 3, not shown, in the head 54. Leakage from the space 42 past the ring 35, Fig. 4, not shown, returns via the ball valve to the now low pressure chamber 26. In a modification, Fig. 5, not shown, the cylinder 12 expands circumferentially away from the head 18 during compression and allows liquid to meter through radial ducts in the surface of the head abutting the end of the cylinder 12. In this modificaation a check valve may be associated, with the tube 25.
