摘要： A method and apparatus for lining a pipe, e.g. an aluminium pipe, with a thermoplastic material, in which either the inner surface of the pipe or the external surface of a tube of thermoplastic material is coated with an adhesive layer, the tube is inserted in the pipe, a purely radial force is applied to press the plastic tube against the inner surface of the pipe, and axially progressive heating is applied to render the thermoplastic material into a plastic state.

摘要： A fluid displacement device is described which may be used as a pump, a motor or a device such as a vibrator for concrete. It includes a body having at least three, and preferably four or five wall portions, which are disposed one after the other along the axis of the body, discrete chambers being formed behind each wall portion, which may, for example, be a toroidal diaphragm, means being provided to feed an operating fluid under pressure to the discrete chambers to move the wall portions transversely to the axis of the body in a sequence to cause displacement of an external fluid axially of the body. When used as a motor, movement of the external fluid axially of the body will cause displacement of the wall portions and thus flow of the operating fluid so that power may be derived therefrom.
摘要翻译：描述了可用作泵，电动机或诸如混凝土振动器的装置的流体排量装置。其包括具有至少三个，优选四个或五个壁部分的主体，这些壁部沿着主体的轴线一个接一个设置，在每个壁部分后面形成分立的室，其可以例如是环形隔膜提供了用于将压力下的工作流体供给到离散室的装置，以使序列中的壁部横向于主体的轴线移动以引起外部流体在主体的轴向位移。当用作电动机时，外部流体在主体轴向上的移动将导致壁部分的移位，从而导致工作流体的流动，从而可以获得动力。
