  • Patent number: 9931770
    Abstract: A foam composite with a skin formed in one shot by charging plastic powders or minute particles together with polyolefin pellets that can be cross-linked and foamed in a mold, and heating the mold while rotating. The composite absorbs almost no moisture, having satisfactory strength, being excellent as an insulating material. Further, providing a covering of a non-foaming or a slightly foaming material to the pellet of polyolefin that can be cross-linked and foamed, and conducting the forming, foamed granules as a core, and a covering of a reinforcing member for the core.

  • Patent number: 8147733
    Abstract: Plastic foam has excellent heat insulation properties, however, moisture absorption is causing a decrease in the heat insulation, and plastic foam has almost no mechanical strength. Therefore, a heat insulation material that absorbs almost no moisture and has satisfactory strength is desired to appear. According to the present invention, a foam composite with a skin can be formed in one shot by charging plastic powders or minute particles together with polyolefin pellets that can be cross-linked and foamed in a mold, and heating the mold while rotating. The composite absorbs almost no moisture, having satisfactory strength, being excellent as an insulating material. Further, providing a covering of a non-foaming or a slightly foaming material to the pellet of polyolefin that can be cross-linked and foamed, and conducting the forming, foamed granules of preferably 5 to 50 mm largeness as a core, and a covering of a reinforcing member with 0.05 to 0.

  • Patent number: 4960268
    Abstract: A spacer holder arrangement includes a support sheet of a self-supporting nature, at least one side of the support sheet having a low adhesive-bonding ability. A pair of concentric inner and outer spacer elements of an annular shape are disposed on the one side of the support sheet to provide a performed spacer, each of the inner and outer spacer elements having adhesive layers formed respectively on opposite sides thereof. One of the adhesive layers is interposed between each of the inner and outer spacer elements and the support sheet to bond them releasably together. The inner spacer element has a central hole therethrough which is coaxial with an aperture formed through the support sheet so that a guide rod can be passed through the aperture and the central hole.

  • Patent number: 4421413
    Abstract: An apparatus which can continuously produce highly-stable emulsified liquid is substantially characterized in that a casing is provided with a plurality of stators mounted on the inner surface of the casing and a plurality of agitator blade rotors which are concentrically and rotatably disposed relative to the stators and that several minute gaps are defined between the stators and rotors. By making at least two different kinds of liquid pass through such minute gaps from one end of the casing to the other, an emulsified liquid having high stability can be obtained from the other end without increasing flow resistance.
