Manipulator assembly for testing the material of a pipe elbow from the inside thereof, the pipe elbow being secured to a pipe union extending from a pressure vessel openable for receiving therein a vertically extending manipulator mast having an arm carrying a manipulator, the manipulator being movable by the arm in vertical direction, rotatably about the axis of the mast and in direction of the longitudinal axis of the arm and transversely thereto, the manipulator includes a multimember vehicle drivable in direction of the pipe-union and pipe-elbow axis, the members of the vehicle being articulatingly connected to one another and having extensible and retractable support legs for supporting the respective vehicular members centered relative to the inner periphery of the pipe elbow, the support legs having roller members at the end thereof for transporting the vehicular members in axial direction of the pipe union and the pipe elbow, the vehicular member located at the head of the multimember vehicle being a test system carrier and being drivable with the vehicle in axial direction of the pipe union and the pipe elbow, the test system carrier having a test system fastened to at least one test arm and mounted so as to be rotatable along predetermined test tracks in circumferential direction of the pipe elbow, drivable radially inwardly and outwardly with the test arm and centerable on the respective center of the pipe elbow, the vehicular members and the test system carrier being mutually engaged by articulating couplings and longitudinally adjustable drive members so that, in an extended readiness position thereof wherein the manipulator is disposed in front of the pipe union, the vehicular members and the test system carrier are oriented in axial direction of the pipe union, are centered on the pipe union center and are rigidly coupled to one another, whereas in a travelling position thereof wherein at least the test system of the manipulator is located within the pipe elbow, the vehicular members and the test system carrier are loosely coupled to one another so that they adapt themselves to the curvature of the pipe elbow as they travel in axial direction thereof.
摘要:
A method for bending a component made of a thermoplastic material. The component involved is in particular a sleeve-shaped component for a personal care appliance such as a dental care apparatus or the like. For the component to be bent it is heated up to the plastic's softening point. The component is brought into engagement with a forming rail and, during a relative movement of the component and the forming rail, is bent against the forming rail by means of a bending tool. As this occurs, the engagement surface between the component and the forming rail varies continuously.

An apparatus is provided for use with a pressurized-water reactor's steam generator having a manifold chamber enclosing the bottom side of a horizontal tube sheet having holes therethrough in which are mounted the tubes of a heat exchanger tube bundle, the manifold chamber having a manhole giving access to the tube's bottom side to permit internal inspection or repair of the tubes by registration of an end of a flexible guide conduit with the tube sheet holes and through which a flexible carrier can be guided for insertion via these holes in the tube sheet and through the tubes extending from the tube sheet's other side. The apparatus is a light-weight fixture which is manually insertable through the manhole and comprising a beam, means for detachably supporting the beam horizontally in the chamber beneath the tube sheet's bottom side, a horizontal cantilever arm having one end provided with means for supporting the aforementioned guide conduit with its end pointing upwardly and means for mounting the other end of the arm on the beam for horizontal movement of its end having the guide conduit supporting means. The carrier is a flexible hose insertable through any one of the heat exchanger tubes, and being tubular, the carrier hose can carry conductors from an inspection or repair device mounted on the inner end of the carrier hose, back to the relatively safe, remote location for measuring or controlling purposes. The apparatus has additional features.
