  • Patent number: 10948374
    Abstract: A tub drain overflow test system employs a kit with a connecting pipe with a front cylindrical portion having an inner threading and an intermediate annular flange coaxial with the front cylindrical portion. The front cylindrical portion extends through an overflow hole of a tub so that the annular flange, optionally with a seal ring, abuts the rear surface of the tub wall. A test cap has outer threading that mates with inner threading of the front cylindrical portion. The test cap has an annular flange and a breakaway test seal with a projecting grip tab. The test cap has an inner lip that provides a catch for inwardly extending tabs on a fixture to attach. The test cap allows the overflow drain to be tested. A seal portion is removed to provide access to the opening and the finishing fixture is mounted in place.

A test cap has outer threading that mates with inner threading of the front cylindrical portion. The test cap also has an annular flange and a breakaway test seal with a projecting grip tab. The test cap has an inner lip that provides a catch for inwardly extending tabs on a finishing fixture to robustly attach. The test cap allows the overflow drain to be tested and then a seal portion is removed to provide access to the opening and the finishing fixture is mounted in place.

  • Publication number: 20060165832
    Abstract: A melt stream flow path is formed in the fixed part (20) of an injection moulding tool (12). A sonotrode (38) is arranged for direct contact with moulding material passing through the flow path in use, for directly vibrating the material and thus improving the melt flow characteristics of the moulding material as material is being injected into the tool (12). The sonotrode 38 extends directly into the flow path, or forms part of the wall of the flow path. An extrusion apparatus (50, 80) is also provided with a sonotrode (38) extending directly into a flow path, or forming part of the wall of a flow path formed in a modified die block.
