IPC: B65D88/12
Filed: 1985-10-04
Abstract: A portable pressure valve in the form of a welded steel tank having four upright substantially planar side walls (1 to 4) welded together at adjacent edges to form an assembly that is rectangular in horizontal cross-section. Top and bottom walls (5, 7) are welded to the side walls, a relief valve (11) is mounted on the top wall and a discharge valve (25) is mounted on the bottom wall. A steel frame comprises an upright (26 to 29) at each of the four junctions between adjacent side wall edges and a reinforcing structure (e.g. 36, 41, 47, 48, 49) for each side wall is welded to and extends between each pair of uprights and is also welded to the respective side wall, in order to give to the wall the strength necessary to withstand the expected pressures. Reinforcing structures are associated with the top and bottom walls for the same purpose. Base members are welded at the feet of the uprights and provide a horizontal base plane for the assembly. <IMAGE>

Title: Pruning shears
Inventor: FREILICH MAX
IPC: A01G3/02
Filed: 1987-05-21
Abstract: Pruning shears comprise first and second handles 12, 14 pivotally connected at 32, and having respectively gripping ends 16, 18 and mounting ends 20, (22 Figure 1). A cutting blade 26 is carried by the first handle 12 on the mounting end (22) and an anvil member 24 is pivotally connected 34 to the mounting end (22) of the second handle 14. The anvil member 24 includes an arcuate cam slot 36, with the two ends 38, 38' of the slot 36 extending radially outwardly relative to the surface 30 of the anvil 24 positioned opposite the cutting surface 28 of the cutting blade 26. A cam follower 40 is carried by the first handle 12 and extends within the cam slot 36 whereby pivotal movement of the handles 12, 14 relative to each other produces relative movement between the cam follower 40 and cam slot 36. This results in the anvil moving along the cutting blade 26 as the handles are moved towards each other, so that the surface 30 is substantially parallel to the cutting surface 28 during a substantial portion of the cutting stroke. The anvil has a serrated angled end portion to retain e.g. a branch being cut. <IMAGE>

Title: Ultrasonic testing of mineral insulated cable during manufacture
Inventor: VINNICOMBE FREDERICK JOHN
IPC: G01N29/27
Filed: 1990-04-04
Abstract: In a method of manufacturing mineral insulated cable in which the metal tube from which the sheath is to be formed is formed from an advancing metal strip (T) which is folded into tubular form and whose edges are continuously welded together (25), any defects in the weld are identified and located by continuously introducing ultrasonic vibrations into the welded region. These vibrations either interact with a defect in the welded region to produce an echo or undergo a change in signal strength arising from transmission past a defect. The advancing tube is continuously monitored to detect any echo or change in signal strength caused by such a defect or a fault in the insulation and, in response to any such identification, the advancing tube is automatically marked to indicate the location of the defect. <IMAGE>
