  • Patent number: 5474102
    Abstract: This invention relates to a fluid distribution manifold, where the input piping is inserted in through the manifold's circular intake opening and onto its cylindrical input port. The manifold's intake opening leads through a cylindrical path to a closed terminal end. Along the inner manifold wall, there are arranged in a sequence, which may be in a straight line, a series of straight lines or rows, a spiral, or an alternating 90- or 180-degree arrangement, a number of distribution outlet openings and their respective ports, which may be barbed or ribbed on their outer surface. The manifold has the further utility of being expandable to larger sizes. This is achieved by removing the closed terminal end from one manifold and then inserting and connecting that open terminal end in through another manifold's circular intake opening and into its intake port.

  • Patent number: 5391064
    Abstract: This invention relates to an in-line and frame independent electric blower half-housing, with cylindrical walls or essentially nonparallel interior walls constructed of an elastomeric material, and which is thereby acoustically silenced and is also easily disassembled for maintenance. The blower half-housing consists of one piece. The blower half-housing was designed for use in the spa industry, as an air blower, but has applications in other industries.

  • Patent number: 5224844
    Abstract: This invention relates to an in-line and frame independent electric blower housing, with cylindrical walls or essentially nonparallel interior walls constructed of an elastomeric material, and which is thereby acoustically silenced and is also easily disassembled for maintenance. The blower housing consists of two halves and may be adapted to house a larger motor, through the fitting of an adapt or collar device between the two halves of the blower housing. The blower housing was designed for use in the spa industry, as an air blower, but has applications in other industries.

  • Patent number: 5156642
    Abstract: This invention relates to a fluid distribution manifold, where the input piping is inserted in through the manifold's circular intake opening and into its cylindrical intake port. The manifold's intake port has an intake restraint rim on its inner surface in order to prevent the intake piping from being inserted too far into the manifold. In some embodiments, the manifold also has a glue trap located below the intake restraint rim, and of approximately the same dimensions and geometry as the intake restraint rim. The manifold's intake port leads to a cup- or parabola-shaped intake reservoir, where fluid is briefly housed prior to its distribution through several distribution output opening, and their respective distribution outlet ports. In some embodiments, the manifold's distribution outlet ports each possess an output restraint rim on the inner surface of each of the distribution outlet ports, to prevent the output piping from being inserted too far into the port.
