  • Patent number: 6283128
    Abstract: A hair roller has a multi-layer construction, with all layers being soft and comfortable to allow the user to wear the hair rollers during sleep. The hair roller has an inner cellular foam layer, a compressible intermediate layer made of d-suede or velvet and an outer layer made of satin or silk. The roller may have a solid core. Pair of chenille cord securing members extends from opposite ends of the cylindrical roller body to allow securing of the hair roller in place after a strand of hair has been wound on the roller body.

  • Patent number: 5184640
    Abstract: The invention relates to a device for preventing communication through pipe lines of high security institutions. A flapper valve is provided with a valve seat having a plurality of teeth extending into the center of the opening formed in the valve seat. A pivotal flapper opens or closes the valve by abutting a seating face of the valve seat or moving away, under the force of a fluid flow, and allowing passage of waste water from a plumbing fixture to the main waste conduit. A water trap seal is optionally and/or separately mounted for delivering an additional amount of water into the conventional waste trap to fill in the waste trap with fluid and prevent undesirable communication. An independent conduit connected to a water supply deilvers water to a reservoir which is fluidly connected with a conventional jet conduit of a waster system upstream from an outlet point of the jet conduit into the main waste trap.

  • Patent number: 5159620
    Abstract: The invention relates to a propeller assembly, particularly suitable for use with axial flow pumps. The propeller assembly is provided with a cam-operated rotatable propeller blade compression shaft which rotates in response to a detected increase load on the propeller blade. An elongated rod connected to a power source transmits movement to a spring which, in turn, transmits the movement to the cam. To accommodate tilting of the propeller blade during changing of the pitch, a hub outer surface is formed convex and the inner surface of the enclosing shroud is formed concave. The radii of curvature of the hub and the shroud are generally complementary to the radius of curvature of the inner and outer surfaces of the propeller blade, respectively.

  • Patent number: 5111000
    Abstract: An enclosure for an electrical distribution unit which includes a transformer provides for a semi-buried positioning of the transformer to allow easy access to electrical conductors of a power source. The enclosure includes a housing unit and an underground vault within which at least part of the housing unit is positioned. The housing unit extends partly above the ground, so as to allow easy access to connections for the distribution unit from the ground level. An inclined front wall of the housing unit facilitates such connections. A hingedly attached cover closes a part of the inclined front wall of the housing unit above the ground and prevents adverse effects of the environment on the electrical distribution unit positioned within the housing unit.

  • Patent number: 5062968
    Abstract: This invention relates to filtering or straining of fluids where the suspended solids removed by filtration must eventually be discharged from the filter as a "dry cake" discharge. The apparatus provides for the use of a central flow tube positioned within a filter element which is connected to a filter element drain pipe through a valve, which in case of multiple filter elements within a filtration vessel, controls draining of all elements. To assist in detecting a defective or malfunctioning filter element, a sample conduit with a sample valve is provided independently for each filter element.

  • Patent number: 5024560
    Abstract: The invention relates to a method and apparatus for protection against coastal erosion. The protection barrier is formed from a plurality of protection members which are secured together to form a mat of a desired configuration. Each protection member which is formed as a toroidal body, preferably from a discarded tire casing, is at least partially filled with concrete which is deposited about the circumference of the tire casing and occupies not more than one half of the interior chamber formed by the wall of the tire casing. To facilitate preparation of the protection member for use, a conical insert is provided. The tire casing is lowered down over the conical insert, moving towards the wided base of the insert until a lower bead of the casing rim frictionally contacts the wall of the insert. Concrete is then admitted onto the wall of the insert and moves by gravity into the interior chamber, partially filling it.

  • Patent number: 5005627
    Abstract: An improved tubeless tire inflation device, for sealing between a tubeless tire and a rim during the tire inflation process, is provided, comprising a sleeve having an inside diameter not greater than the largest outside diameter of the tire rim, the sleeve having an axial length such that the sleeve may sealingly span between the rim and the tire. The sleeve is composed of a resilient material, such as belted rubber, which is deformable, yet retains sufficient strength and shape to provide the desired seal between rim and tire. The sleeve is further provided with a layer of compressible material around its entire circumference on at least one end.

  • Patent number: 5000200
    Abstract: The invention relates to hair rollers and provides for the use of a cylindrical tube rolled from a rectangular sheet of flexible material, the sheet having an outer edge which overlaps a portion of the tube. The tube has a pair of opposing transverse edges, each of which is engaged within a spiral groove formed in opposing caps. The caps are rotationally mounted on an elongated shaft, such that rotation of the disks causes advancement of the transverse edges within the spiral groove, changing the diameter of the outer tube, as desired.

  • Patent number: 4996087
    Abstract: The invention relates to a method of making decorative ornaments of personalized nature. The method provides for the use of a three-dimensional ornament which is covered by a coating having acrylic resin and then one-color outline of a design is printed on the coating. The space formed within the outline of the design serves as a coloring space for an individual. A second method provides for the use of a heat-shrinkable plastic sleeve positionable about an object and exposable to heat to cause shrinking of the sleeve to conform to the shape of the ornament. In this embodiment, a one-color outline is imprinted directly on the sleeve prior to positioning of the sleeve on the three-dimensional ornament.

  • Patent number: 4995762
    Abstract: A floating drilling and production unit comprising two independently floating bodies: (1) an outer, larger, substantially cylindrical buoyant caisson with an enlarged skirt around its lower perimeter to dampen sea-induced motions and (2) a wellhead buoy captured within the central well of the outer caisson. The outer caisson supports the weight of the drilling platform, machinery, storage and living quarters and is ballasted and anchored in a manner similar to a conventional semisubmersible vessel. The constant tension buoy supports the wellheads of completed wells and is held in a constant position relative to the ocean floor much like a tension leg platform by the production risers of completed wells, tendons, or a combination of tendons and risers. Production risers are kept taut by the buoyancy of the constant tension buoy. The constant tension buoy has a tapered shape that minimizes contact and interaction between the wellhead buoy and the caisson.

  • Patent number: 4986903
    Abstract: The invention relates to an apparatus for removal of suspended matter from a liquid, such as used for treatment of oil containing water. A cylindrical horizontal vessel is divided into a single gasification chamber and a single degasification chamber by a partition which extends through the interior chamber of the vessel and allows fluid communication between the two chambers. A liquid to be treated is introduced through distribution header(s) adjacent a bottom of the vessel and/or an alternative inlet nozzle which is combined with a gas eductor in order to achieve a more intimate mixture of the gas and liquid. The gas eductor has its outlet slightly above the outlet of the distribution headers.
