Abstract: A manually operated tool engages and draws towards one another opposed spaced flanges of a repair clamp disposed about a leaking pipe for securely maintaining the clamp in position on the pipe over the leak allowing plural nut and bolt combinations on the clamp to be tightened in sealing off the leak. A movable handle has attached thereto first and second pivoting arms adapted for respectively engaging a slot within the clamp's first edge flange and the outer edge of the clamp's second opposed edge flange when the handle is in a first non-use position. Moving the handle to a second use position urges the clamp's edge flanges toward one another drawing the clamp securely about the pipe, while still allowing the clamp to be moved along the pipe over the leak and plural nut and bolt combinations to be securely tightened in sealing off the leak.

Abstract: A light for an industrial stringlight includes a cap having wire channels receiving insulated conductors. Non-interchangeable contact elements are placed in a screw-shell adapted to hold a lamp, and the cap and screw-shell are forced together. The cap is secured to the screw-shell, and insulation-piercing points on the contact elements establish electrical continuity with their associated conductors. The assembly is then overmolded for protection and sealing. A lamp guard is assembled to the overmold and has a bottom section hinged about a horizontal axis to permit replacing the lamp from beneath.

Abstract: A process of making an article of a tungsten-carbide-cobalt alloy with or without an additive of one or more of tantalum, cobalt-nickel, nickel-tantalum, tantalum-carbide, titanium-carbide, niobium-carbide, chromium-carbide, titanium-nitride and diamond dust. The method includes forming a homogeneous mixture of polygonal-shaped powder tungsten-carbide-cobalt and a polygonal-shaped powder additive and a binder including wax and a high molecular weight polyolefin polymer and injecting the mixture under heat and pressure into a metal injection mold to form a green preform of the article. The green preform is immersed in a linear hydrocarbon or a halogenated hydrocarbon or mixtures to dissolve and remove the wax and convert the green preform into a brown preform which is sintered to remove the remainder of the binder and to densify the brown preform into an article having a density not less than 98%. Various tungsten-carbide articles are disclosed.

Abstract: An improved rotary pressure cutting apparatus that cuts, perforates, and scores plies of paper, window materials, label stock, and plastic laminates in conjunction with soft, discontinuous, and/or non-cylindrical anvil surfaces. A light weight, low mass anvil in the form of a metallic sheet is supported in a strike position beneath a rotating blade. The anvil is biased by springs or elastomeric members toward the strike position and moves with the material being cut and the moving cutting blade during a cut. The anvil is returned to the strike position by the biasing member upon completion of the cut.

In a second embodiment, a variable current source is employed in a secondary circuit of an SSCR to control current in the primary circuit. In a third embodiment, both a variable impedance in one secondary circuit and a variable current source in a second circuit of an SSCR are employed for separate and independent control of current in the primary circuit.

Abstract: In general, increased video image contrast is achieved by reducing light transmission through an antistatic/antireflective (ASAR) coating disposed on the surface of the display screen of a cathode ray tube (CRT) by adding an organic dye to the coating. A silane coupling agent is added to the coating to prevent diffusion of the dye out of the coating which gives rise to undesirable water marks on the display screen. However, the silane coupling agent at the required concentrations weakens the mechanical strength of the coating, reduces its electrical conductivity, and changes its light reflective index. To avoid this, two or more different silane coupling agents are added to the ASAR coating with the plural silane coupling agents having an additive, or combining, effect which allows for the use of reduced amounts of the coupling agents and avoids the aforementioned problems. One agent is hydrophobic, while the other bonds to the organic dye.
