  • Patent number: 8511662
    Abstract: Provision of appropriate fixtures for locating components for fabrication, machining and installation purposes is important. Traditionally, solid fixtures have been utilized but these have limitations with regard to consistency of orientation particularly if the fixture is removed from a base support or workbench regularly. By providing sheet elements for sides 2, 3 and spacers 4, 5 a robust structure can be achieved when these sheet elements are secured at corners to a base support 8 and to each other at top portions. In such circumstances the fixture 1 can present location plates 41, 42 upon a locator 43. The locator 43 comprises cross secured plates which extend through at least one cross hole to limit movement of the locator upon which the location plates 41, 42 are presented to axial displacement. Rigidity of the fixture is further reinforced by integrating its structure with its base-plate support.

  • Patent number: 6619643
    Abstract: A mechanism is described for incorporating into a clamping workbench of the type comprising a pair of main clamping jaws (234, 237) and a supplementary clamping jaw (230) which is movable as a consequence of relative movement of the main jaws to engage and clamp a workpiece lying across the main jaws. The clamping movement of the supplementary jaw (230) is generally perpendicular to that of the main jaws. The invention concerns a supplementary jaw (230) having a single actuating arm (238), one end of which is adapted to be pivotally received in an opening (246) in one of the main jaws (237), and the other end of which is slidably connected to the supplementary jaw (230) and held captive therein by pin means (304, 306) extending above and below the captive end of the arm (238).

  • Patent number: 6416046
    Abstract: Supplementary jaw means is described for fitting to a clamping workbench transversely to the main jaws thereof at a position spaced from stop means at the other end of the main jaws, whereby operation of the drive means which moves the main jaws towards or away from each other will increase the distance between the supplementary jaw means and the stop means when operated in one sense, and will decrease the distance therebetween when operated in the other sense. A clamping workbench may be fitted with one supplementary clamping jaw means and a fixed stop for clamping a workpiece therebetween above the main clamping jaws.

  • Patent number: 6382610
    Abstract: A tool to reduce the rotational force on a pipe to be held in a chain vise includes a curvilinear or inverted V-shaped base which saddles the pipe to be held. A U-shaped frame is mounted to the base such that one or more roller bearings may be mounted between the opposing sides of the U-shaped frame. The roller bearings provide a bearing surface for the chain of the chain vise, allowing the chain to be tensioned without applying torque to the pipe to be held. A pair of the tools may be spaced apart upon the periphery of a large pipe with the chain passing over the roller bearings of each tool.

  • Publication number: 20020017752
    Abstract: A portable workbench, comprises a molded plastic base structure and a molded plastic upper work structure. Wheels and a transport handle are mounted on the base structure. The transport handle is constructed and arranged to be manually engaged to move the base structure between a) a storage operative position wherein the base structure is stabily supported on a horizontal surface and b) a storage transport position wherein the wheels rollingly contact the horizontal surface so that the base structure can be moved along the horizontal surface using the handle. The upper work structure is constructed and arranged to be supported on an upper portion of the base structure in a storage operative position. The upper work structure and the base structure cooperate when in the storage operative positions thereof to define a storage space.

  • Patent number: 6339678
    Abstract: A device and a method are described for vaporizing and superheating a sterilizing agent. The sterilizing agent is brought to a first temperature and vaporized with the aid of a heated surface. The vapor is subsequently bought to a second, higher temperature and super heated by means of heating elements. A heater, having super heating channels and heating elements, is connected after a vaporizing chamber. The sterilizing agent is sprayed onto the heated surface, which is heated to the first temperature. The first temperature is lower than the surface temperature at which film boiling begins. The first temperature of the heated surface is sensed and converted into signals for controlling the heating elements for super heating. This sterilizing agent vapor is heated in a counter flow such that the first temperature is kept substantially constant by means of the second, higher temperature and by means of a flow of heat directed in the opposite direction to the flow of vapor.
