  • Patent number: 4167262
    Abstract: A valve of simplified construction, adapted to control fluid of high volume and pressure. The valve plunger is a hollow metal tube, that controls fluid flow by moving radial slots in its peripheral wall back and forth across a seal. The plunger is moved by an air or hydraulic cylinder which is connected to the plunger by a plate ring. The plate ring has a series of holes therethrough that allow the line media to flow through, out of and around the plunger to create a balancing effect and thus decrease opposition to movement of the plunger, which opposition may be caused by forces created by the line media. The improved valve utilizes double-acting seals to isolate a down stream port, and to seal off the increase in pressure downstream when the valve is closed.

  • Patent number: 4165065
    Abstract: My invention is particularly adapted for use in steel-making furnaces which have a charge-receiving vessel comprising a bottom and side walls for containing the molten steel and slag, such as the open hearth and electric furnaces. Lime is a major constituent of steel-making slags but it has a tendency to build up on the furnace bottom after successive steel-making operations. I have discovered that by adding a mineral, such as alumina or the like to the built-up lime and applying heat, the lime and alumina will chemically combine to form another mineral having a melting point low enough so that it may be liquified for drainage from the furnace.

  • Patent number: 4152578
    Abstract: The novel electric heating element is particularly useful as a water heating element, although its use is not so limited. The element comprises the usual metal-sheathed heater having electrical termination at one end of the sheath. The customary water heating element has a sheath of hair-pin formation, with the ends of the two legs of the sheath connected to structure which serves as a mounting member and an electrical connector. Such structure in the present application is of molded plastic with a metal insert.

  • Patent number: 4144445
    Abstract: An open coil electric heater wherein the resistance conductor is supported on a frame. The resistance conductor in this instance, instead of being in the form of a single coiled wire, is composed of a plurality of strands of wire so as to reduce the cost of the resistance conductor while providing adequate surface area. The strands of fine wire or flat ribbon wire are braided into a rope which is formed into a series of reaches in customary manner. At least one of the strands is of a material which will provide strength to the wires that primarily generate the heat and thereby prevent sagging of such wires between wire supports. In a preferred form, the wires are loosely braided to form wide open spaces and insulated support members are projected through certain of the open spaces to support the strands in predetermined position.

  • Patent number: 4143688
    Abstract: Apparatus for dispensing pasty flowable substances, and particularly for dispensing substances such as mustard and catsup for deposit on buns. The apparatus comprises a closed container having a plurality of compartments for containing mustard and catsup. A valve arrangement is associated with the container to uncover selected openings in compartments, and air under slight pressure is introduced into the container to assist in ejecting the mustard or catsup. A control is included to selectively provide for ejection of mustard, or catsup, or both.

  • Patent number: 4138054
    Abstract: The invention relates to means for and methods of forming containers. The means comprises one or more pieces of corrugated cardboard adapted to be inserted into standard bags usually provided by stores for carrying purchased commodities. A cardboard piece is bent along scored lines to a form wherein it will fit within the bag to shape the latter widthwise, the excess upper portion of the bag being folded into the bag and over the cardboard piece to form a container. Another corrugated cardboard piece, if a different width than the first mentioned piece, is bent along score lines to a form wherein it will fit within another grocery bag to shape the latter endwise, the excess upper portion of the bag being folded into the bag and over the cardboard piece to form a container. One of the containers may be inserted into the other to form a dust-proof storage box or a shipping container.

  • Patent number: 4133348
    Abstract: A valve comprising a valve body having a bore, a hollow plunger reciprocable within said bore and having radial ports to control flow of fluid under pressure between various valve body openings. Seals are disposed about the exterior surface of the plunger to seal against fluid flow longitudinally of the bore. The seals are of a type that offer low resistance to movement of the plunger from a static condition, and the exterior surface of the plunger has an extremely smooth finish and is of a comparatively small outside diameter to further reduce resistance to plunger movement. The valve construction is such that whenever a plunger port passes underneath a seal, fluid pressure is always from the inside of the plunger to the outside so that there is a tendency to temporarily lift the seal from the exterior surface of the plunger or at least to prevent the seal from being forced into the plunger port.

  • Patent number: 4119302
    Abstract: The invention comprises the combination of a metal post and staple means for securing an object to the post. The object is preferably a wire barrier, such as a barbed wire, although it may take the form of a roadside sign or highway marker. The post has a Vee cross-section and a metal staple is driven into the Vee to interengage with post surfaces at the opening into the Vee. A portion of the secured object is contained within the bight portion of the staple, and in the case of a wire, the latter extends through the bight portion of the staple and is held securely to the post.

  • Patent number: 4117308
    Abstract: An electric heater, particularly adapted for supplying heat to hazardous areas where the atmosphere in the area contains particles or fumes that are readily ignited. The heater includes one or more heat radiating members, each cast about a sheathed electric heating element. The terminal ends of the heating element extend into a sealed explosion-proof terminal box. The heat radiating members are serially disposed in a tubular casing, and a motor-operated fan blows air through the casing and over the members, the air being heated as it flows over the heat radiating members.Each member is in the form of an annular hub having integral, heat-dissipating fins extending radially thereof. The outer surface of the hub is formed with a contour that is angled or curved in the direction of the air flow, and such contour is constructed and arranged to provide a Venturi effect to draw air from the inner portion of the hub to the outer periphery and thus prevent build-up of excessive heat at the inner portion.
