  • Patent number: 3987625
    Abstract: The combined sensor and control comprises a flow sensor through which passes working hydraulic fluid delivered by a pump through a hydraulic power circuit to a hydraulically operated power mechanism which is subjected to variations in load. The sensor senses incipient changes in a preselected rate of flow of the working hydraulic fluid by detection of very slight changes in the differentials in the pressure of the working fluid at opposite sides of a restricting orifice through which the working fluid is constrained to pass. These differentials in pressure, or pressure drops, operate a pneumatic pressure control device by which pneumatic pressure supplied to an actuator through a circuit, isolated from the working hydraulic circuit, is controlled. The pressure control device causes the applied pneumatic pressure to be varied almost instantly in a manner analogous to the slight variations in the normal preselected differential in pressure across the orifice.

  • Patent number: 3987548
    Abstract: A bite tray for taking a bite registration impression of the posterior teeth of a full set of teeth includes a bib and frame so shaped and arranged that, in the absence of some occluding posterior teeth, beginning with the rearmost occluding teeth and continuing progressively forwardly therefrom as occluding corresponding teeth are absent, the frame and bib can be adjusted and manipulated forwardly to include in the bite registration impression of not only the remaining posterior teeth but also an impression of the incisors and progressively more of the labial teeth without striking the labial surfaces of the jaw or of the labial teeth. The frame is so proportioned and the bib so manipulatable that they make possible the taking of such bite impressions in true centric occlusion of the teeth.

  • Patent number: 3976799
    Abstract: The carnivore food is composed essentially of ground raw meat and dried cooked cereal, optionally supplemented with other protein, and extruded as continuous extrusions each composed of successive slugs adhered to each other in end to end relation by the natural fluids freed from the meat by cutting and extrusion forces. The amount of cereal is thoroughly impregnated by the freed juices, leaving an excess of freed juices only sufficient to adhere the food particles together and moisten the extrusion. The freed juices of the meat, and supplement, if any, are substantially the only moisture present.

  • Patent number: 3964180
    Abstract: A plurality of like detachable stance control supports are detachably connected to spikes of a golf shoe of the type having conventional spikes arranged in two rows spaced apart from each other laterally of the sole and heel of the shoe at opposite sides of the midportions of the sole and heel, one row being an outer row near the outer lateral limit of the sole and heel and the other row being an inner row near the inner lateral limit of the sole and heel. The control supports are connected to selected spikes, respectively, of the outer row and aid a golfer in assuming the proper stance, in addressing the ball, by tilting of the shoe and heel of the right shoe, and therefore the right foot, so that the weight supported by the right leg is directed through the inner side of his foot more nearly beneath the instep.

  • Patent number: 3949450
    Abstract: A length of wire of uniform composition throughout has end portions of circular cross section bent into the form of mutually interengageable loops with free ends. The loops can be interengaged and then drawn into a knot by endwise tension applied to the wire. The portion of the wire intermediate the end portions is of uniform oval cross section of such less area than the circular cross section of the end portion that, when the wire is subjected to a direct tensile pull, its load capacity approaches more nearly the load capacity of the knot than in prior wire bale ties. The longest cross sectional dimension of the intermediate portion of the wire is juxtaposed flatwise against the bale in the installed condition of the tie.

  • Patent number: 3945396
    Abstract: A check valve has a body with a seat therein and a valve plug movable toward the seat to closed position and away from the seat to open position. The valve plug has a forward face facing toward the seat and body inlet and a rear face facing away from the seat and toward the body outlet. The plug, at its rear face, has a stem of smaller diameter than the rear face so that an annular area of the rear face of the plug is exposed rearwardly toward the body inlet. The stem has fins thereon of a shape to impede the return flow of fluid relative to the stem in a direction toward the seat and thereby assist in rapid closure of the valve. The rear face of the plug is concave rearwardly and slopes inwardly from its outer periphery toward its axis at a very slight angle to further assist in rapid closure, while reducing outward radial components of flow of return fluid.

  • Patent number: 3933967
    Abstract: Seamless hollow molding rubber articles are produced by concurrently molding two article halves with mateable edges which extend toward each other. Portions of the mold plates and core are maintained continuously at the full vulcanizing heat until the halves of the articles have been vulcanized to about 60 percent of the optimum vulcanization of the material, except for thin strata defining the mateable edges. By cooling at the portions which form these strata, these portions are maintained at a lesser temperature to cause the reaction in these strata to progress slightly beyond the scorching or blowing stage to dimensional and volumetric stability. At this stage, the mateable faces of the edges are substantially free from the usual "skin" effect which effect would render them non-fusible. The mold is then opened, the core is removed, and the mold is reclosed.

  • Patent number: 3930576
    Abstract: A jewelry display and packaging box has a bottom and a cover connected together by a hinge for swinging to open and closed positions. The bottom has an upwardly facing display panel on which a piece of jewelry is detachably supported in a display position. The cover has a large concavity therein which faces toward the box bottom in the closed position of the cover. A jewelry support is mounted on the box and has one or more jewelry supporting portions which are disposed in spaced relation to the walls of the concavity, and above the level of the panel. The portions are arranged to suspend one or more articles of jewelry in spaced relation above, and in overhanging relation to, that portion of the display panel which is adjacent the hinge, and so that the articles extend partway into the concavity and hang in spaced relation to the concavity walls and can dangle and swing freely, whereby rays of light reflected and refracted from each dangling article continuously shift directions.
