  • Patent number: 4394705
    Abstract: A hose assembly of limited conductivity designed to dissipate static electric charges, such as encountered in paint spraying. The hose assembly includes a reinforced hose 1 fitted over the nipple 15 of a stem 13, and a shell 14 holding the hose 1 in compression over the nipple 15 of the stem 13. The novel element is a stripe of conductive polymer 11 in the cover 9 of the hose 1 extending from the static drain 7 to the surface of the hose 1. When the shell 14 is compressed over the hose 1, the conductive stripe 11 is seated and held in secure electrically conducting relationship with the inner diameter of the shell 14.

  • Patent number: 4285168
    Abstract: A plastic bearing and wear surface is disclosed which has low friction fibers protruding from its surface. The bearing is made by filling a plastic matrix with low friction fibers whose mechanical properties relate to those of the matrix in such a manner that when the matrix is machined, the matrix material will selectively be removed leaving some of the fibers imbedded in the matrix with their free ends protruding from and distributed over the machined surface.

  • Patent number: 4188478
    Abstract: Novel polyamides are prepared having end groups especially selected to impart special properties to the polymer. These polyamides are prepared by utilizing anionic polymerization processes and the end groups can be of a type that, under existing methods, normally will hinder or completely stop the anionic polymerization reaction. The hindering effect of these end groups is largely overcome through the formation of novel initiator compounds that enables the polymerization reaction to proceed with extreme rapidity at comparatively low temperatures despite the presence of these end groups.
