Title: Apparatus for feeding a tube-bending machine
IPC: B21D43/00
Filed: 1958-04-01
Abstract: 875,428. Angular bending. HILGERS MASCHINEN-UND APPARATE BAUANSTALT. April 1, 1958 [April 6, 1957], No. 10441/58. Class 83 (4). Means for feeding a tube to a bending machine, which includes a rotary former to which the tube is clamped and around which it is bent and a mandrel for supporting the unbent trailing part of the tube, comprises apparatus movable to a position in line with the mandrel so that a tube may, by pusher means, be pushed over the mandrel, the apparatus being then moved back out of range of a free tube end projecting from the bending means. Tube 16 from a storage container 17 are pushed, by a slide 19 operated by an hydraulic piston 18a, into an inclined guideway 24 attached to a carriage 21. The carriage 21 is then moved along rails 20 to a position in line with a mandrel 15 of a bending machine including a rotatable former 12 and a clamp 13. In this position a pair of superposed tubes 16a are pushed from the carriage 21 and over a pair of superposed mandresl 15 by an hydraulic piston 22 until the tubes engage a stop. This causes the jaw 13 to clamp the tubes to the former 12. The piston 22 is withdrawn and the carriage 21 moved back to the container 17. Pressure rolls 14 are applied to the tubes and the former 12 is rotated to bend the tubes therearound. The tubes may be fed to the mandrels by rollers moved together to grip the tubes. The feeding means may be moved axially from the bending means instead of transversely.

Title: Control device for dust bin lifting tipper
IPC: B65F3/04
Filed: 1960-05-24
Abstract: 908,178. Tipping dust-bins into refuse vehicles. ZOLLER [nee KEHL], E. K., and ZOLLER, H. March 24,1960 [March 24, 1959], No. 10462/60. Class 78 (4). A pneumatic device which automatically controls the lifting and tipping of dust-bins into a refuse vehicle after the sequence of events has been initiated by movement of a single control comprises a two-way valve 79, Fig. 1, supplied through a conduit 67 with compressed air, and connected to one of a pair of lifting cylinders 21 by a conduit 77, 78 and to a tipping cylinder 24 by a conduit 80. As described, compressed air is simultaneously supplied to the two-way valve 79 and check valve 69, the latter being opened when a hand lever 70 is depressed to allow air to pass through conduits 32, 76 to lift pistons 20 in cylinders 21. This raises a dust-bin supported by hooks 74 and resting against a plate 75. In rising one of the pistons 20 passes over a bore 35 in one of the cylinders, thus allowing compressed air to pass through conduits 77, 78 to the two-way valve 79. At this instant the bin has been raised to its highest point and is ready to be tipped. The compressed air moves a diaphragm 91, Fig. 3, in the valve 79 to the right thus moving inlet valve 92 so that air from the supply conduit 67 is supplied through conduits 80 to the cylinder 24. The tipping piston 25 is pushed down and the bin is tipped by an arm 5 when a rod 4 is rotated by gears 27 and piston-rod 26. When the tipping piston 25 moves over a bore 81 compressed air flows through a conduit 82 to a shut-off valve 83 which interrupts the supply of air through the conduit 32 to the lifting cylinders 21. To swing the bin back to the ground the lever 70 is moved to its initial position to connect the lifting cylinders 21 to the outlet of the check valve 69. Simultaneously the air flows from the valve 79 through conduits 78, 77 and cylinder 21 to the atmosphere. The diaphragm 91 now moves to the left, allowing the air to exhaust from the cylinder 24 through the conduit 80, past the piston 93 and through outlets 84. A conduit 84a may be provided between outlets 84 and a housing 29 having vents to the atmosphere. When the cylinder 24 is exhausted a cylinder 85 swings the bin into a vertical position whereupon the bin is returned to the ground by hooks 74.

Filed: 1966-03-07
Abstract: 1,187,031. Porous coating. PORVAIR Ltd. 6 June, 1967 [7 March, 1966 (2)], Nos. 9977/66 and 10702/67. Heading B2E. A water vapour permeable porous sheet material comprises three superimposed layers, each layer being formed from or with the aid of a solution of a polymeric plastics material in a solvent, the material of the first layer being shaped to form the layer and the solvent removed from it, the material of the second layer then being deposited on the first layer and the solvent removed from it, and the material of the third layer being deposited on the second layer and the solvent removed from it. The first layer may be formed by impregnating a permanent support e.g. a fibrous support with a solution of the polymer, or the first layer may be formed by depositing the layer on a temporary support as disclosed in the Specification 1186342. The polymer may be a linear elastomeric polyurethane and the solvent dimethyl formamide. The second layer may be made by forming a mixture of the polymer dissolved in a suitable solvent and a removable solid filler, forming the mixture into a layer on the first layer removing the solvent and removing the filler by leaching with a leaching agent. The polymer of the second layer may also be a polyurethane and which in the solid phase at 25C. may have tacky, rubbery properties. The material of the third layer may be deposited on the second layer before the second layer is rendered porous. In an example a felt made from retractable staple nylon fibres by a mechanical entangling process involving needle punching is impregnated with a solution of a polyurethane in dimethylformamide, immersed in water and washed until all the solvent is removed, dried and slit. The smooth surface of the felt is doctor knife coated with a layer of polyurethane solution in cyclohexanone containing sodium chloride ground to 20-25 microns. The coated layer is dried and doctor knife coated with a layer of a polyurethane solution in dimethylformamide containing sodium chloride of 20-25 microns size particles and pigment. The composite material is then immersed in water and washed and dried. The surface of the surface layer is then sprayed with a lacquer mixture of polyurethane in dimethylformamide. In example 2 a layer of polyurethane solution in dimethylformamide is formed on a temporary support comprising a sheet of sintered high density polyethylene, and then immersed in and washed with water to coagulate the layer and remove all the solvent. The layer is then doctor knife coated with second and third layers as in example 1. The composite sheet still attached to the temporary support is immersed in water and washed with water and then dried. The surface is then sprayed with dimethylformamide.
