    摘要: A process and device for rehabilitating old pipelines laid in the ground is described. The extent of above-ground prefabrication of a hose-shaped lining for the old pipeline is increased and a closed system for guiding a heatable pressure medium is described. Above-ground, a calibration hose (4) is inverted into the flat-lying lining hose (6) or a lining hose (6) is inverted into a tubular film using compressed air. The lining hose (6), which is provided with the calibration hose (4) and with the tubular foil, is drawn through a shaft into the old pipeline and by means of a heatable pressure medium, which circulates in a closed system, is pressed against the interior wall of the old pipeline and is kept in this position until the resin of the lining hose has hardened. With the process, underground sewer pipes are rehabilitated.

    摘要: Apparatus for introducing a lining hose containing curable resin from a main pipeline, e.g. a sewer mains, into a lateral connection, e.g. a service pipe for a property, includes a shield having an arcuate configuration and complementing an inner contour of the main pipeline in an area of an inlet port of the lateral connection. The shield has an outlet opening destined for alignment with the inlet port of the lateral connection and is defined by a cross section which corresponds to a cross section of the inlet port of the lateral connection. A pipe having one end extends from the outlet opening inwardly into the main pipeline, and a conduit is connected to the other end of the pipe and provided for conducting a pressure fluid for everting a lining hose and an associated calibration hose in the lateral connection, with the calibration hose being secured adjacent the outlet opening of the shield.

    摘要: A faulty junction between a main pipe and an entering branch pipe is repaired and sealed by using a bladder which is carried between two bearing blocks. The bladder is prepared with a resin impregnated mat, which, when the bladder is pulled and turned into a position center to a pipe junction lines and seals the pipe junction upon application of a pressure medium to the bladder. Positioning of the bladder is performed under TV remote-control.

    摘要: A free standing supply column for supplying energy and for delivering communications to and away from implements or working devices, especially in offices. The column has a base support or base plate, and radial, horizontally swingable supporting arms installed on the column for the implements or devices. The supporting arms have a horizontal section and a vertical section. Several vertical pipe sections are arranged in a circle about the column middle axis in or around the upper part of the column. On these pipe sections the vertical sections of the swingable supporting arms with supply lines are held in such a way as to be individually adjustable in height.

    摘要: A worktable, especially an office table, which includes two side legs, at least one support bar which connects these legs, and a table-top. Also provided are rigidly interconnected support, connecting and fastening structures which permit different height positions and inclinations of the table-top with the aid of simple tools. The connecting, support, and fastening structures save space, and give the table the necessary stability and freedom from vibration. For this purpose, the fastening plates have holes which are equally spaced from, and are rotationally symmetrical to, the middle point of the plate. The bars have at least two fastening and support surfaces for the table-top and are eccentrically connected with the fastening plates in such a manner that in different rotary positions of the two plates, the fastening and support surfaces of the bars are located at different levels or height positions. The table legs have threaded holes arranged to correspond with the fastening holes of the plate. The table-top is held directly on the support bars by fastening structure on the underside of the table-top.
