  • Patent number: 4892427
    Abstract: A dispenser for dispensing metered amounts of a viscous material includes a rigid tube which defines a compartment for the material, a discharge passage at one end of the tube, a push button activated and reciprocatingly movable rod which moves back and forth between two positions in the tube, and a sealing plunger which moves step-wise on the rod, from the push button end to the discharge end. Each activation of the push button expels a metered amount of the viscous material. The plunger is formed of a short inner tube section which makes sealing contact with the rod, an outer tube section which is in sealing contact with the interior surface of the tube and a radially extending, ring-shaped, rib which connects the two sealing tubes to one another. In a preferred embodiment, the radial cross-section of the plunger exhibits and H-shape. A metallic gripper is secured to the plunger and has a free end which is inclined toward the rod.

  • Patent number: 4762144
    Abstract: A cover for a valve (10) has a housing (20) mounting internally a component (24), with a collet (28) being located with play through an open end of the component (24). Resiliently deformable jaws (36) of the collet (28) co-operate with a profiled inner wall of the component (24) for opening and closing of the jaws (36) upon axial movement of the collet (28) relative to the component (24). When positioned on a stem (12, 14) of the valve (10), the cover is movable downwardly thereon to operate the valve and is freely rotatable, but on movement upwardly the cover is clamped by closing of the jaws (36) on the stem (12, 14). The housing (20) is formed of a material with a high degree of resistance to vandalism.

  • Patent number: 4531782
    Abstract: Mining equipment for steering the cutting horizon of a mining machine cutter which is mounted on a ranging arm and which in use makes repeated traverses along the working face, comprises a boom urged into contact with the mine roof formed on a previous traverse of the machine. The boom is urged towards the mine roof by a ram hydraulically connected to a piston and cylinder device such that movement of the piston of the device is in accordance with that of the ram. Movement of the piston rod activates a flow control valve controlling operation of a ram controlling ranging of the arm.

  • Patent number: 4367899
    Abstract: A holder assembly for a sensitized cutter tool mountable on a cutter head of a mining machine comprises a holder adapted to hold the tool. The holder is pivotal supported abutting a mounting sensor means provided to sense cutting reaction on the tool, the cutting reaction tending to urge the holder to pivot about the mounting.

  • Patent number: 4343904
    Abstract: Animal cells are grown in a vertically disposed cylindrical vessel containing a stack of parallel spaced-apart discs inclined at least 5.degree. from the horizontal and mounted to a rotatable axial shaft. The vessel is closed by a top plate having a plurality of inlets and a bottom plate with an outlet, and contains an external pumping loop for circulating contents of the vessel from the bottom to the top of the vessel. Growing of the cells is carried out by substantially filling the vessel with a mixture of animal cells and growth medium, allowing the cells to settle on the disc surfaces and then rotating the axial shaft at a speed of at least 5 rpm while continuously circulating the vessel contents from the bottom to the top of the vessel. This process and apparatus provides efficient mixing and ensures a homogeneous system within the vessel.

  • Patent number: 3946525
    Abstract: The buffing machine of the present invention includes one or more buffing wheels to which workpieces are successively presented on a continuously traveling conveyor wherein the workpieces are rotatably mounted. The axis of workpiece rotation is adjustable to any angle desired relative to the conveyor travel and the axis of a buffing wheel. The angle the axis of rotation of the workpiece makes with the buff wheel axis is selected so that rotation of the buffing wheel imparts a desired speed of rotation of the workpiece.
