摘要： The invention discloses resulting products and a method of producing high voltage resistant members employed in electrical installations such as bushings and insulators. The method comprises placing a sheath of unvulcanized elastomer on a core, which for example is a fiberglass rod, for example by extruding the sheath thereon, and mounting at least partially vulcanized sheds on the sheath therealong, then vulcanizing the sheath to form an integrated high voltage resistant member. The sheath is unvulcanized when the sheds are mounted thereon and then the sheath is heated to vulcanize it, in order to bond it to the sheds and to the core. The sheds also can be molded directly onto the sheath together therewith in steps along the length of the core. For producing a bushing, the sheath is placed on a core formed of a conductive stud wrapped with paper and metal foil and then impregnated with a suitable hardenable resin.

摘要翻译： 本发明公开了所得到的产品以及用于诸如衬套和绝缘体的电气装置中使用的耐高压构件的方法。该方法包括将未硫化弹性体的护套放置在例如玻璃纤维棒的芯上，例如通过在其上挤出护套，并在其上安装至少部分硫化的护套，然后硫化护套以形成一体的高度耐电压元件。当棚子安装在其上时，护套未被硫化，然后护套被加热以使其硫化，以便将其粘合到棚屋和芯部。棚也可以沿着芯的长度的步骤直接模制到护套上。为了制造衬套，将护套放置在由纸和金属箔包裹的导电柱形成的芯上，然后用合适的可硬化树脂浸渍。

摘要： Described herein are butt-welded polymeric articles and means of effecting joinder of crosslinked polymeric articles by means of such welds. The invention finds application in, e.g., forming large-diameter heat recoverable sleeves from cross-linked polymeric sheet for, e.g., corrosion-proofing pipe joints and the like. The weld is effected by heating under compression a thermoplastic insert containing a peroxide or other heatedactivated crosslinking agent.

摘要： Helicoid products comprising several continuous tiered strips are made by superposing at least two continuous strips with their edges overlapped, incurvating the strips and durably adhering together the contacting faces of the strips. The resulting helicoid product may be conformed to a mandrel and cured, vulcanized or otherwise treated to acquire a durable tubular helicoid form. This technique is particularly useful in making helicoid coverings that may be repeatedly put on and removed from tubes, rods, wires and the like, as coverings, firesleeves, or insulation, for example.
