摘要： A fusion bead testing device (13) is provided for testing the strength of a fusion bead (11) removed from a pipe joint (6). The testing device (13) comprises a first pressing means (19) for exerting a force against the fusion bead (11). If the fusion bead (11) splits as a result of the applied force then the fusion bead (11) fails a quality control test and the fusion bead (11) and consequently the pipe joint (6) from which the bead (11) was removed are deemed too weak. The fusion bead-testing apparatus (13) comprises an automatic split detection device (27, 127) for detecting a split in the bead (11).

摘要： The invention relates to pipe couplings and particularly to the provision of a welded connection between adjacent pipe lengths (1, 2) of plastics material. In this regard such techniques as butt welding and electrofusion welding are widely known and practised, at their cost, but necessary when it is the supply of gas that is involved. The object of the present invention is to provide a welded connection suited to the less exacting conditions of pipe lines for trunking or for the supply of water, which objet is met by a method comprising locating over the adjacent ends of the pipe lengths, a coupling sleeve (3) of a coupling sleeve and the external diameters of the pipes being such that the coupling sleeve is a close sliding fit on the ends of the pipes, applying an external drive (6) to the coupling sleeve to rotate the coupling sleeve on the pipe ends at a rate such that heat generated by friction melts the interface between the coupling sleeve and the pipe ends, and whereby following cessation of rotation, and on cooling, an effective weld is formed between the coupling sleeve and each pipe end.

摘要： The invention relates to cutters (1) for cutting connecting holes in plastics pipes (8). Predominantly the connection of a service to an existing plastics pipe is by way of an electro-fusible saddle (7) being located on and sealed to the pipe and the cutter introduced down the stem of the saddle to cut a hole in the pipe and thereby connect the pipe to a spigot or branch on the saddle to which a service line is connected. The cutting of the hole in the pipe inevitably results in leakage that can be dangerous when the pipe is carrying gas. There are constructions of cutter that attend to the question of leakage at the point that a hole is cut but which still have a leakage problem at the point that the cutter is withdrawn and before a cap is applied to the stem. The object of the invention is to eliminate this problem, which objective is met by a cutter construction comprising a cylindrical blade (2), a threaded body portion (3) attached to the blade, and there being an integral first length of rod or tube (4) on the body portion to the opposite side of the cylindrical blade portion together with a second length of rod or tube (15, 16) extending from an detachably attached to the said first length, the junction between the said first and second lengths serving as a visual indicator means. Thus, once a hole in the pipe has been cut the said second length maintains its contact with a sealing ring in the stem during the retraction of the cutter until the visual indicator confirms that the cutter has been fully withdrawn following which the exposed second length is removed without the aid of additional tooling with the seal maintained against the first length of rod or tube, the fitting of the cap providing additional security against leakage.
摘要翻译：本发明涉及用于切割塑料管（8）中的连接孔的切割器（1）。主要地，服务与现有塑料管的连接是通过位于管子上的电熔鞍座（7）并将其密封在管子上，并且刀具沿着鞍座的杆向下引入以在管中切开一个孔将管道连接到与服务线连接的鞍座上的插口或分支。管道中的孔的切割不可避免地导致当管道携带气体时可能是危险的泄漏。切割机的构造考虑到在切割孔被抽出的点处以及在帽被施加到杆之前在孔被切割但仍然具有泄漏问题的点处的泄漏问题。本发明的目的是消除这个问题，即通过包括圆柱形刀片（2），连接到刀片的螺纹主体部分（3），并且具有一体的第一长度的杆或管（4）在所述主体部分上延伸到所述圆柱形刀片部分的相对侧以及从可拆卸地附接到所述第一长度延伸的第二长度的杆或管（15,16），所述第一和第二长度作为视觉指标的手段。因此，一旦管道中的孔已被切割，则在切割器缩回期间，所述第二长度保持与杆中的密封环的接触，直到视觉指示器确认切割器已被完全拉出，接着暴露的第二长度为在没有附加工具的情况下移除，密封件保持抵抗杆或管的第一长度，盖的配合提供了额外的安全性以防泄漏。

摘要： The invention relates to butt welding and is particularly concerned with the provision of self-determined cooling times during which pipe ends must remain clamped in the machine to ensure the creation of an effective weld. Most effective butt welding machines are already known such as are described in British Patent No. 2191976, but even machines of this sophistication leave largely to the discretion of an operative the degree of time that the machine must be left after the welding stage and before the clamps can safely be removed. Almost inevitably this results in the pipes being clamped in the machine far longer than is actually necessary and the object of the invention is to provide for shortened cooling times that are self-determined by the machine and by ambient temperature conditions. The invention involves the provision of control means employing parameters sensed and/or measured to limit the cooling stage to a duration no more than is required having due regard to ambient temperature conditions and the amount of heat input to the pipe ends during the heating and/or bead-up stage.
