摘要： The present invention relates to a pipe fitting comprising a cylindrical body, a radially deformable locking piece, a seal and a compression ring which is maintained fast with the body, while being free to slide axially with respect thereto. The ring defines with the body an annular space in which the seal and the locking piece are maintained fixed so that the fitting forms a unit.

摘要： A configured thermoplastic product is formed of two interfitting preformed parts which are bonded into an integral unit by heat fusion of the interfitting surface portions of the parts. The apparatus for forming the product includes means to grip one part to restrain rotation thereof and means for gripping and rotating the other part at high speed while the parts are relatively advanced axially as determined by guide means. The method utilizes the apparatus to telescopically interengage parts having an interference fit so as to generate by friction between the parts as the parts advance toward selected interfitting relation heat at the interfitting surface portions of the parts sufficient to soften and fuse said parts at said interfitting surface portions.
摘要翻译：配置的热塑性产品由两个相互接合的预制部件形成，这些部件通过部件的相互配合的表面部分的热熔合而结合到一体的单元中。用于形成产品的装置包括夹持一个部件以限制其旋转的装置以及用于在由引导装置确定的部分相对地前进的同时高速夹持和旋转另一部件的装置。该方法利用该装置将具有过盈配合的伸缩式互相连接的部件以部件间的摩擦力产生，因为部件在部件的相互配合的表面部分处朝向选定的相互配合的关系热的方向前进，足以使所述部件在所述配合表面部分。

摘要： An improved corrosion resistant seal for compression coupling devices includes threadably engageable male and female coupling members. Each of said respective coupling members has an insulating, moisture resistant, resilient, polymeric coating, such as a polyvinylchloride coating bonded to the metal substrate. Both male and female coupling member coatings terminate in respective annular resilient flange portions. Each of the annular flange portions extends radially of its respective coupling member in a manner whereby threadably engaging and advancing male and female members results in contact of the respective flange portions providing an effective moisture seal therebetween and an effective insulating coupling that prevents galvanic and chemical corrosion thereof. A further embodiment of the improved corrosion resistant seal for compression couplings includes a male coupling member coating continued beyond the adjacent resilient flange portion and terminating in a threaded portion adjacent the matching threads of the male coupling member. The male coupling member completely engages the female coupling member when all the threads of the female coupling extend over all the threads of the male coupling member and engage the threaded portion of the male coupling member coating. An effective moisture seal is first provided by the contact of the respective resilient flanges of the male and female coupling members when the threaded portion of the female member initially engages the threaded portion of the male member.
摘要翻译：用于压缩联接装置的改进的耐腐蚀密封件包括可螺纹接合的凸形和阴型联接构件。每个所述相应的联接构件具有绝缘，防潮，弹性的聚合物涂层，例如结合到金属基底的聚氯乙烯涂层。阳联接构件和阴联接构件涂层均终止于相应的环形弹性凸缘部分中。每个环形凸缘部分以其相应的联接构件的径向延伸，使得螺纹接合和前进的阳和阴构件导致相应的凸缘部分的接触，从而在它们之间提供有效的湿气密封，以及有效的绝缘耦合，防止电化学和腐蚀其中。用于压缩联接器的改进的耐腐蚀密封件的另一实施例包括连续超过相邻的弹性凸缘部分并且终止于与阳联接构件的匹配螺纹相邻的螺纹部分中的阳联接构件涂层。当阴联接件的所有螺纹延伸到阳联接构件的所有螺纹上并且接合阳连接构件涂层的螺纹部分时，阳连接构件完全接合阴连接构件。当阴构件的螺纹部分最初接合阳构件的螺纹部分时，首先通过阳联接构件和阴联接构件的相应弹性凸缘的接触来提供有效的防潮密封。

摘要： A pipe coupling comprising a body with a bore adapted to receive the pipe as a sliding fit and formed with a recess for an O-ring to encircle and seal against the pipe. A nut threaded on the body has an internal wedge surface, and a longitudinally split pipegripping collar encircles and grips the pipe and has an external wedge surface which is complementary to and cooperates with the wedge surface in the nut. The external wedge surface on the collar is relieved intermediate the ends of the collar, by a rectangular-section annular groove so as to decrease the area engaging the nut without decreasing the effective overall length of the wedge surface.
