Title: Backing and alignment ring assembly for welding pipes
IPC: B23K37/053
Filed: 1973-11-27
Abstract: 1426788 Welding by fusion R P GRIFFITHS 25 Nov 1974 [27 Nov 1973] 55038/73 Heading B3R A backing and alignment ring assembly for welding together pipes end-to-end comprises a segmented ring mounted by way of two resilient conical members on two hubs which are axially relatively movable to effect radial expansion or contraction of the ring. The conical members are slitted to form resilient fingers and are preferably of heat resistant material, e.g. stainless steel. The ring segments may be cast in stainless steel or copper alloy or be of ceramics. As shown, a ring 10 comprises twelve segments 23 having interengaging lips and recesses 24, 25 which prevent inward flow of weld metal and which have angled faces 26 to assist in weld metal removal. The ring also has a circumferential bead-forming groove 27. Segment location is by engagement of segment pins 29 with conical member peripheral slots (30). The hub of one conical member is in screw-threaded engagement with an actuating rod 11 having a flange 14 bearing on the other hub. Rotation of the rod in one direction draws the hubs together and radially expands the ring against the pipes. A separable rod actuating device comprises an extension rod 12 provided with a slot 16 for engagement with a tongue 15 of the rod 11, and a surrounding extension tube 13 having a screw 17 engageable in a threaded hole 18 in said other hub. The extension rod and tube 12, 13 may be of any desired length. A disc 19 adjustably mounted in the extension tube 13 is engageable with a pipe end to axially locate the ring assembly. In a similar arrangement (Fig. 1, not shown), the separable rod actuating device is dispensed with. In Figs. 5-7 (not shown), conical member peripheral slots engage ribs (34) of the segments. In Fig. 8 (not shown), the hubs are axially relatively movable by an hydraulic or pneumatic piston and cylinder device disposed between the hubs, actuating pressure being applied through a hose which if flexible enables the ring assembly to be passed round pipe bends either by a pull-cord or the hose itself.

IPC: B66B5/02
Filed: 1968-12-02
Abstract: 1,248,417. Lift cages. A. A. L. L. HOUILLE, and J. L. A. SEE. 2 Dec., 1968 [1 Dec., 1967], No. 57062/68. Heading B8L. In the event of a power failure, a lift cage 1 is lowered relative to the hoist cable 13 by a lazy-tongs linkage 3, 4, 7, 8, 10, 11, extension of which is effected by the weight of the cage and controlled by an hydraulic damper 14, 15. Fig. 5 shows an embodiment in which a safety lever 16, operated by a ram 18, holds the linkage in the closed position in the event of an hydraulic failure. To lower the cage distributer 27 is operated to connect ducts 30, 31 and 32. This lowers the pressure in chamber 24 of the ram 18 below that in the chamber 23 thus moving the lever 16 clockwise to the disengaged position. When the piston of the ram 18 has moved far enough to connect a duct 35 to the chamber 23 the damper 14 begins to discharge liquid to the tank 33 and the lazy-tongs linkage extends lowering the cage. When the cage is eventually lowered on to its stops the linkage is re-folded by its own weight and the pressure in the tank 33. The tank 33 may comprise a piston and cylinder arranged below the cage such that lowering of the cage to the bottom of the shaft compresses the piston into the cylinder and returns the damper 14 and ram 18 to their original positions.

Abstract: 1,181,648. Pneumatic shuttle - conveying apparatus. SIEMENS A.G. 24 Dec., 1968 [28 Dec., 1967], No. 61258/68. Heading B8A. In a pneumatic shuttle-conveying system of the kind having a plurality of despatch and receiving tube systems connectible with one another in a central multiple switching arrangement, the despatching stations are provided with mechanical selector devices which transmit the destinations of despatched shuttles to be stored in electrical switching equipment allocated to the multiple switching arrangement. The electrical switching equipment includes a number of data stores equal to the number of despatching tube systems, and a shuttle store is provided for each system at the central multiple switching arrangement the capacity of each store being equal to the destination storage capacity of the associated data store. The introduction of shuttles into a particular despatching line is carried out by arranging that an associated call-up circuit in the electrical switching equipment for determining the sequence in which shuttles are fed into the line, cyclically and successively samples all stations which indicate the presence of a shuttle and then establishes a connection between the selector contact devices at the particular station and the data store and at the same time releases a lock to release the shuttle into the despatching line. The mechanical selector devices can also act as a station store whereby, when all the storage positions in the data store are utilized, other shuttles can still be introduced into unoccupied stations and the corresponding pieces of destination information set into the selector devices.

A device for releasably clamping the end of a conductor comprises a body 301 having two intersecting bores 5, 7 at an acute angle to each other so that a conductor inserted in the bore 7 is clamped against the side of the bore by a clamping head 8 which is spring-loaded at 213 and located in the other bore 5. A facing piece 314 holds the clamping means in place in the body 301. A plurality of such clamping devices may be incorporated in a single body (Fig. 1, not shown) which may be made of insulating or conductive material or a composite of the two (Fig. 6, not shown). A clamping head 8 may be mounted at both ends of a helical spring thus enabling two clamping points to be obtained from a single spring (Fig. 5, not shown). The conductor may be removed from the device by the insertion of a pointed implement alongside the conductor in the bore 7. The top of the clamping head 8 may be serrated or roughened to prevent the implement from slipping off the head (Fig. 14, not shown). In a further embodiment, Fig. 8, comprising a plurality of double-ended springs, the middles of the springs are secured to a rigid rod 327 which may be moved laterally in either direction along the axis of the springs to release the locking action of the clamping heads 8. In other cases the rods may pass through the clamping heads themselves (e.g. Fig. 34, not shown). The shape of the head may be in the form of circular steps as shown in Fig. 4, or alternatively as simple steps along one flat face (Figs. 26, 27, 28, not shown), or a roller (Fig. 35, not shown) and the spring may be a leaf spring (Figs. 40, 41, not shown). In other embodiments the locking action is released pneumatically (Figs. 15 to 19, not shown) or hydraulically. A toggle switch incorporating the invention is described (Figs. 37 to 39, not shown).
