  • Patent number: 11939250
    Abstract: An ion removing system having an ion removing apparatus that includes a fine bubble generating part generating fine bubbles and that causes the fine bubbles to adsorb metal ions to remove the metal ions from the hard water due to supply the fine bubbles generated by the fine bubble generating part into the hard water. In addition, the ion removing system includes a primary-side flow path to supply the hard water to the ion removing apparatus, a separating apparatus that separates crystals of a metal component deposited by crystallizing the metal ions removed from the hard water by the ion removing apparatus, and a secondary-side flow path that takes out, from the separating apparatus, treated water obtained by separating the crystals. The primary-side flow path is provided with a supply-side backflow prevention mechanism.

  • Patent number: 11905190
    Abstract: A submersible vessel which can act as a reusable bath bomb delivery system is provided. The vessel may include a housing and an opening port. The interior of the housing and ports form a chamber, which can be segmented into multiple sub-chambers. Inlet one-way valve(s) and outlet one-way valve(s) are provided on the vessel. To use, the chamber is partially filled with a mixture including an effervescent material. When water is introduced through the inlet valve, it reacts with the effervescent material, releasing carbon dioxide and dissolving the other ingredients in the mixture, building pressure in the chamber. When the pressure builds to a certain level, the inlet valve(s) are closed, and the outlet valve(s) are opened. The outlet valves may be positioned such that when the fluid and gas is expelled, the force generated may cause the vessel to spin or be propelled in the bath.

  • Patent number: 6090336
    Abstract: A method and apparatus for manufacturing an injection-molded article having an outer film on an exposed surface. The method includes securing the film about its periphery within a mold cavity prior to injection of molten material into the cavity. One way of securing the film is by applying vacuum pressure through peripheral holes in a frame surrounding the mold cavity. Molten material is injected into the cavity, behind the film and the film slips from its initial position to be forced against a wall of the cavity by molten material being injected into the cavity. The apparatus includes a frame for a molding apparatus, adapted to initially secure the film in place prior to movement of the core block into place and to permit the film to slip from its initial position to be forced against the cavity wall as molten material fills the cavity.

  • Patent number: 6030568
    Abstract: A method for producing a fibre reinforced three-dimensional product comprises depositing of long fibers in a mould consisting of a frame in which a carrier net for the fibers is suspended. The individual layers of a formed plane laminate are positioned in such a manner that only a first end is secured at a frame side. Said first ends are secured at different frame sides. In this manner it is possible, in a pressing procedure giving the product is three-dimensional shape, to obtain a virtually even distribution of the fibres, even in areas which are subjected to the longest move away from the plane original laminate. In this manner sound well-defined properties are obtained in the three-dimensional product formed.

  • Patent number: 5976295
    Abstract: A method of molding a component such as a headliner or sun visor for the interior of automotive vehicles is molded from different thermoplastic materials from the same family that can be subsequently recycled as a whole without the need of separation into its constituents. The interior component is a multi layer composite of polyester (PET) finishing fabric, a resilient layer of bicomponent polyester fiber padding composed of blend of a low melting point fibers and high melting point fibers, and a relatively stiff core layer of polyester/glass fiber composite of polyester and glass fibers. The different fibers of the core layer are blended into a thin and porous sheet which is cut to size. The cut sheets are consolidated and molded under heat and pressure into a light weight, dense and structurally strong composite. A mold charge comprises the polyester/glass fiber composite layered with the bicomponent.

  • Patent number: 5972264
    Abstract: A method for fabricating fiber-reinforced composite structures, including centrifuge rotors, by resin transfer molding (RTM) is disclosed. The method involves loading reinforcing fibers into a mold and then injecting resin into the mold to coat the fibers to form the composite structure. Two types of reinforcing fibers are used--fabric preforms at the surfaces of the structure and chopped fibers at the interior of the structure. Also disclosed is a fiber-reinforced composite structure comprising a skin layer of reinforcing fabric, chopped fibers distributed throughout the interior of the structure, and epoxy resin that binds the fabric and chopped fibers together into a fiber-reinforced composite structure. The resin transfer molding method is especially useful for fabricating composite centrifuge rotors.

  • Patent number: 5961764
    Abstract: A manufacturing process for reverse building complex-shaped vehicle fuel tanks using complementary female mold half sections which, when joined together about their mating peripheral edges, exactly duplicate the fuel cavity framework of the vehicle into which the completed tanks are to be mounted. Whereas previous reverse building processes employed light weight, air-curable, non-tear fabric such as nylon fabric reinforcement to both halves of the female molds, such fabric is applied only to the mold for the top half of the fuel tank of the present invention. Self-sealing, autoclave curable materials are used in the bottom half of the fuel tank, thereby providing improved ballistic protection to the lower portion of the tank.
