    摘要： A multi-functional hollow body for use as a boom rest or a boom and mast carrier for sailboats that is lightweight and may be positioned and secured to the boat without damaging the surface of its deck. The hollow body includes a neck and cap to allow it to also function as a liquid container. When the hollow body is sealed in an empty condition, it may also function as a flotation device, kickboard or a buoy.

    摘要： An extruder screw and a method for extrusion to achieve high output rates with thermally sensitive plastic materials and without thermal degradation problems involving the use of a single flight metering type extruder screw having an initial feed zone, distal metering zone, and a transition zone interconnecting the feed and metering zones. In particular, improvements in the extrusion of thermally sensitive plastics such as PVC are achieved through use of a compression ratio of approximately 2:1, a constant lead and pitch, and a proportioning of the length of the feed zone, transition zone, and metering zone relative to the total length of the zones of 27-33%, 23-25%, and 45-48%, respectively. To achieve cooler and more uniform mixing with rigid PVC, polyethylene and like materials, an improved arrangement for using rings of mixing pins is provided.
