    • A double sided polypropylene knit loop fabric comprises at least one and preferably both of the inner and outer loops comprised of polypropylene yarn forming cantilevered loops from a knit fabric. Polypropylene has many different characteristics than those of cotton or cotton blends. Accordingly, by making at least one of the loops, if not both of the loops, and the tie yarn out at least substantially, if not principally, polypropylene, a fabric can be produced which has different characteristics than a cotton fabric of similar construction.
    • 双面聚丙烯编织圈织物包括由针织织物形成悬臂环的聚丙烯纱线组成的至少一个,优选两个内圈和外圈。 聚丙烯具有许多不同于棉或棉混纺的特性。 因此,通过使至少一个环(如果不是两个环)和连接纱至少基本上(即使不是主要地)聚丙烯,也可以生产出具有与类似结构的棉织物不同的特性的织物。

    • An implantable lead in the form of an electrical conductor wire having an insulating layer of impervious plastic surrounding the surface of the electrical conductor wire and further having an exterior surface covering of porous PTFE. The impervious plastic insulating layer is preferably a thermoplastic and most preferably a thermoplastic fluoropolymer such as ETFE, FEP or PFA. The exterior surface covering of porous PTFE offers improved flexibility and biocompatibility in comparison to conventional lead wires having silicone exterior surfaces, while the impervious plastic insulating layer prevents loss of insulating integrity resulting from wetting out of the porous PTFE exterior surface by body fluids. Methods of making the implantable lead are also described.
    • 电导体线形式的可植入引线,其具有围绕电导体线表面的不透水塑料的绝缘层,并且还具有覆盖多孔PTFE的外表面。 不透水的塑料绝缘层优选为热塑性,最优选热塑性含氟聚合物,例如ETFE,FEP或PFA。 与具有硅氧烷外表面的常规引线相比,多孔PTFE的外表面覆盖物提供了改进的柔性和生物相容性,而不透水塑料绝缘层防止了由体液润湿多孔PTFE外表面导致的绝缘完整性损失。 还描述了制造可植入引线的方法。

    • An apparatus for playing a racquet and ball game in a confined space comprises an enclosed playing arena having a generally rectangular playing area; upright walls surrounding said playing area; a roof extending over said playing arena and extending between opposed upper regions of the walls; and a pair of upright spaced substantially parallel barriers. The barriers extend transversely of the playing area to divide the playing area into two substantially equal player's zones. The player's zones each include a ball service boundary marked on and extending transverely of each of the player's zone. An upper edge of each of the barriers is spaced from the roof.
