  • Patent number: 4606730
    Abstract: A method of producing bimetal electrodes in which a core of copper is enclosed within an outer covering of a nickel alloy. The alloy is extruded into a relatively small diameter, deep cup by first forming a cylindrical blank with a rounded indentation in one face and thereafter extruding the cup using a punch having an end conforming with said indentation to form a central opening having a diameter at least three times the diameter of the punch. A cylindrical copper core is then firmly seated within the cup, which is then extruded by two stages to form an elongated, cylindrical blank. In one embodiment, the end is finished by trimming away a flaring skirt portion at the open end and thereafter upsetting the blank. In another embodiment, the flared skirt portion of the nickel alloy is bottled inwardly and pressed flat against the exposed end of the core so that no scrap is produced.

  • Patent number: 4604810
    Abstract: A diameter gage is disclosed which measures a plurality of diameters on a workpiece after the workpiece has been machined. First and second U-shaped gage frames mount first and second gage blocks relative to a gage platform, and this gage platform is moved vertically upwardly to a position whereat the gage blocks of each set straddle different ones of the plurality of different diameters on the workpiece. Parallel leaf springs provide low friction mounting of the gage blocks, and also provide urging means to urge the gage blocks into contact with the opposite sides of the workpiece. An electrical output gage is moved in accordance with the relative movement between the two gage blocks of each set to provide an error signal which is passed to the numerical control to correct the machining diameter of the machine tool which machines successive workpieces.

  • Patent number: 4605369
    Abstract: A gas-fired burner of the radiant type includes a boardlike heating element constituted by a porous matrix of refractory fibers, the periphery of one side of the heating element being bonded to and in fluidtight engagement with an open end of a sheet metal box functioning as a gas plenum. A combustible gas mixture is fed into the plenum and forced through the porous heating element for burning at the outer face thereof. The boardlike heating element is retained in position by a strip of perforated metal fixed to the outer surface of the sheet metal box and extending about the edge of the heating element, the strip being bent over to hold the edge of the heating element against the box. A multilayer blanket of thermal insulating material wrapped around the sheet metal box is held in position by bent metal tabs and by the bent strip of perforated metal retaining the heating element. A low cost diffuser assembly ensures optimum gas mixture flow within the plenum.

  • Patent number: 4604603
    Abstract: A dual temperature probe-type thermostat is illustrated in which a rod and tube probe is mounted at one end with a swivel on the switch body. The swivel structure is simplified to provide a bearing member engaged and positioned by the rod during swiveling movement. Both switches are operated by a single operator which is guided and positioned solely by the switches themselves. One switch is provided with a calibration cam to eliminate any need for selective assembly.

  • Patent number: 4601311
    Abstract: A pilot-operated, directional control valve having a ported slide and cooperating, non-interflow, shear-type seals. The valve achieves a high flow capacity for a given size by utilizing both of a pair of opposed sleeve seals to conduct flow through the valve. The valve response is improved by a hydraulic bias of supply pressure on the slide which requires operation at a high pilot pressure.

  • Patent number: 4598514
    Abstract: A fire-rated type suspension ceiling grid runner is disclosed having expansion means intermediate its ends which collapse when the runner expands due to elevated temperatures occurring during a fire or the like. The runner provides a boxlike panel supporting flange along the lower end of the web thereof in which slots are formed to define a flange segment and connecting legs. When the expansion means collapses, the flange segment is laterally displaced as a unit and remains connected to each adjacent portion of the boxlike flange by at least two longitudinally spaced legs. The displaced flange segment functions as a bridging beam which continues to connect the adjacent portions of the flange and maintain them in alignment so that a grid formed of the runners can continue to maintain proper support for panel even when fire conditions occur.

  • Patent number: 4598521
    Abstract: A grid system for suspension ceilings is disclosed having an end connector providing an inverted, U-shaped end portion adapted to nest over the upper edge of an associated web of a runner extending through the intersection. An integral tongue is bendable through an aperture formed in such associated web to releasably lock the connector to the through runner. The end connector is mounted between opposed, parallel, vertical webs on the associated runner by tabs which extend through web slots. The separate connectors and the runners can be formed of materials having different thicknesses so that the material forming the web and the material forming the connector can be selected to provide the required strength without excessive use of materials. The connectors can be used both in main run cross-run systems, and in basket weave systems.

  • Patent number: 4599196
    Abstract: Process for the conditioning of waste, such as radioactive or toxic waste, whose acidity can inhibit polymerization reactions, e.g. waste containing cation exchange materials.This process consists of incorporating the waste into a liquid epoxy resin at ambient temperature and then bringing about the polymerization of the resin by means of a hardener, in order to obtain a solid block.A hardener containing at least one compound having at least one NH.sub.2 group in an adequate quantity for blocking the active sites of the cation exchange materials present in the waste or for neutralizing the acidity of the humid waste and for polymerizing the epoxy resin is used.This process can be more particularly used for conditioning resin beds used for the purification of the water of nuclear power stations.

  • Patent number: 4597699
    Abstract: A quick-connect and quick-disconnect mechanism includes a male member which may be received in a female socket member. Cam means is journaled in an eccentric cam follower surface in the socket and is capable of rotation about a second axis displaced from the axis of the socket. A locking surface on the cam means faces in a longitudinal direction opposite the entrance of the socket and opposite that of a lockable abutment surface on the male member. An aperture in the cam means is sufficiently large to accommodate the entrance of the lockable abutment surface on the male member. The cam means is rotatable within the cam follower surface to move the cam locking surface with a radially inward component and a component of movement in a longitudinal direction away from the entrance of the socket to engage the lockable abutment surface to lock the male member in the socket. The cam means may also have an expelling surface to aid in expelling the male member from the socket.

  • Patent number: 4596095
    Abstract: An underfloor cable tray assembly is combined with a raised floor and is intermediate the raised floor and a subfloor which supports both in an electrical equipment room. Uniformly spaced stanchions support raised floor joists and floor panels to establish the raised floor for the equipment. Instead of having the communication cables strung without order on the subfloor, the underfloor cable tray assembly is provided to route such communication cables in an orderly manner among the various pieces of equipment. The cable tray assembly is formed from modular cable tray sections having a U-shape in cross section and selected from straight sections, horizontal bends, horizontal tees, and crosses. Splice plates and threaded fasteners interconnect these selected cable tray sections to form the complete cable tray assembly.
