  • Patent number: 5771730
    Abstract: The equipment forms metal profiles on a stretch-bending machine on which a profile to be formed is held at its end by jaws connected to stretching rams and to a system for bending it against a convex punch member fixed to a toolholder table of the machine. The equipment includes a die member which is pressed against the punch member, once the profile has been bent against the punch member. An elastic material mandrel is placed inside the profile and the mandrel is compressed-expanded so that it presses the profile against internal surfaces of the punch member and of the die member when closed one against the other.

  • Patent number: 5378134
    Abstract: A press has a fixed lower platen, and an upper platen which is movable vertically by means of an actuator. A former corresponding to the article which is to be obtained is placed on the lower platen via a thermal insulation member, the former including channels for circulation of a heat exchange fluid. The material to be formed is placed on the former. The upper platen carries an assembly which has a resilient membrane, the periphery of which is sandwiched between a lower frame and a cover connected to a source of fluid under pressure, sealing between said membrane and the lid being ensured by the clamping pressure between these two parts which results partly from the force exerted on the moving platen and partly from the pressure of the fluid.

  • Patent number: 5303553
    Abstract: A device for connecting two tubes end-to-end. At least one of the tubes is movable longitudinally to be connected to the other tube. A screwthreaded nut joins the two tubes. The first tube has at its end an outside screwthread of diameter d1 and pitch p1. The second tube has at its end an inside screwthread of diameter d2 greater than d1 and pitch p2 different than that p1 of the first tube. One of the screwthreads is continuous and the other is discontinuous by virtue of longitudinal lands subtending an angle at the center of the tube equal to that of the screwthreaded longitudinal lands. The nut 3 has an inside first screwthread compatible with that of the first tube and an outside second screwthread compatible with that of the second tube. The device further includes a system for immobilizing the tubes against rotation and a system for rotating the nut.
