To overcome errors due to delays occasioned by successive transfers a counter for emitting a signal at a predetermined count sends a transfer signal from its lowest denomination in advance of completion of the related cycle. As shown the units multi-cathode tube T1 emits a transfer signal from cathode 1K1 so that in a predetermined count of 1000 cathode 4K1 of tube T4 is energised in advance of the attainment of the count. When therefore the units tube reaches cathode 1K0 gate 2 opens to emit the required signal P1000.

Abstract: 1,114,765. Rod couplings. D. A. STEWART. 30 July, 1965 [29 Sept., 1964], No. 39576/64. Heading F2G. [Also in Divisions E1 and E2] A holding and locating device for two overlapping structural members, for example reinforcing rods for reinforcing concrete, comprises spaced parts capable of surrounding both members in sideby-side relationship and a wire 12 connecting the two parts. The ends of the wire 12 extend beyond the parts into two U-shaped portions which prevent the passage of an associated member through the associated part. In a further embodiment, the parts comprise loops of flat metal strip joined by two metal strips, further metal strips being welded across the free ends of the loops to form abutments for the members (Fig. 3, not shown). The loops of flat metal strip may be in a figure-of-eight configuration (Fig. 4, not shown) or each part may be formed of two separate circular loops welded together (Fig. 5, not shown). The parts may be of figure-of-three or 8-shape (Figs. 6, 7, not shown). In some cases the major portions of the members may be in axial alignment and, in such cases, the end of one of the members is shaped to form an inflexion.

Abstract: 1356934 Propulsion of tracked vehicles HIRAM WALKER & SONS (SCOTLAND) Ltd 10 Nov 1971 [19 Aug 1970] 40040/70 Heading B7L [Also in Division B8] Conveying apparatus for rollable loads, e.g. barrels and cylinders and wheeled or roller-  supported containers and pallets, comprises tubular track sections 1, 2 providing fluid trunking for inflatable tubes 8A, 8B on which the load is conveyed. Portions of the track are longitudinally connected by couplings 5, and transverse ducting 9, 10 connects opposite portions of the track via housings 13, 14. The housings are connected to the ends of the tubes 8A, 8B by pipe bends 15, 16 which have tongued valve members 22, 23 loaded to seat on the ends of the pipes 15, 16 to form hinged discharge valves. Each housing 13 also has a tongued valve 25 controlling exhaust of the housing to atmosphere. In operation, pressure fluid introduced into a track rail 3 passes into the tubes 8A, 8B through valves 22, 23 after closing the exhaust and discharge valves and passes from the tubes to atmosphere through the exhaust valves 25 of a track rail 4. On depositing a barrel &c. on the upstream ends of the rails, the tubes 8A, 8B are nipped between the barrel and the track sections and the pressure difference at opposite sides of each tube results in application of a rolling torque to the barrel. By switching the pressure fluid to the rail 4 the direction of roll of the barrel is reversed. In Figs. 5-8 (not shown), means are provided to permit inward rocking of the rails to accommodate themselves to the convexity of the barrel. To reduce power requirements, supply for the pressure fluid may be in the form of a closed circuit. Specification 1,183,023 is referred to.

A method of forming an assembly of concentric ring-shaped contacts separated by insulating rings for use as a slip-ring or a jack-plug comprises forming, successive layers of insulation, each layer being stepped back at at least one edge from the preceding layer, and the layers carrying conductive bands on to which metal may be deposited by electrolysis to form the contact rings. In the first embodiment, Fig. 1, the insulating material is a thin sheet 2, of polyethylene terephthalate, slightly tapering in shape, and carrying L-shaped conducting strips 4, 5, 6, 7 and 8, formed as described in Specification 1,003,575. The strip is wound on to a stainless steel core 1, so the edges lie in spirals forming the successive steps. The ends of the limbs 9, 10, 11 and 12 of the conducting strips are exposed at the lower edges of the spiral enabling electrical connections to be made to the metallic bands 4, 5, 6 and 7 respectively. The assembly is immersed in an electro-plating bath and rings are built up on the bands 4, 5, 6 and 7 as shown at 14. 15, 16 and 17 (Fig. 3). Tool 19 is used to true up the rings facing in the direction of the axis of the core. The assembly is encapsulated in a suitable plastics material, e.g. an epoxy resin, and then trued up along the dotted line III in a lathe. In the second embodiment, Fig. 7, a layer of insulating material 20 is polymerized on to core 1 and the end is masked by a composition 31 readily soluble in a solvent which does not dissolve the polymerized layer 20. The layer 10 is treated with a catalyst solution as described in Specification 1,003,575, and a metallic layer deposited thereon. A further layer of insulating material is polymerized to the metal layer stepped back a little from the end, and the process is continued. The metal steps 25, 30, 35, are used as bases for the buildup of contact rings as in the first embodiment. In a third embodiment, which is similar to the first embodiment, a differently shaped sheet of insulator is initially used.
