Abstract: A sensor which can be held around a cylindrical body has elastic parts which have expansion-sensitive elements on the inner surfaces. The elastic parts are pressed against the cylinder surface under high pressure by bracing the two sensor halves, such that the expansion-sensitive elements engage the cylinder surface by friction force and thus can detect the surface expansion occurring.The expansion-sensitive elements are protected against mechanical influences. Thus expansion measurement strips can be applied to the cylinder surface without adhesive and can be used several times.

Abstract: A pump comprising a pump body having a control valve for controlling working fluid flow from the pump body to an actuator through a joint. The joint is connected mechanically to the pump body through a washer made of a material different from that of the pump body. The washer has a side surface held in contact with the pump body at a junction. The pump also includes an annular seal member provided to keep the junction from exposure to the environment. In an embodiment of the invention, the seal member is placed in an annular groove formed in the outer peripheral surface of the pump body. The seal member may have a side surface in fluid-sealing contact with the surface of the washer so as to keep the junction between the pump body and the washer from exposure to the environment.

Abstract: A process for the cyclic control of extruders which facilitates the precise control of an extruder to achieve maximum output and at the same time optimal quality of the extruded profiles. Accordingly therefore the extrusion velocity is controlled in such a way that the profile exit temperature is constant and equal to a prescribed temperature trajectory. Thereby the extrusion velocity and the profile exit temperature are measured over the complete cycle interval for each and every cycle k, and with the knowledge of the relationship between these quantities and the trajectory of the extrusion velocity of the cycle k, the trajectory of the extrusion velocity for the (k+1)th cycle is determined, such that the control error and the control effort are as low as possible and after completion of the (k+1)th extrusion cycle the whole process is repeated for every subsequent cycle therefore until the whole extrusion program is completed.
