Abstract: The present invention generally relates to an apparatus and a method of measuring various conditions of the pipeline. In one aspect, a method of using a tool in a pipeline is provided. The method includes placing the tool in the pipeline. The tool having a rotational control member constructed and arranged to maintain the tool in a preselected rotational orientation relative to the pipeline. The method further includes urging the tool through the pipeline while maintaining the preselected rotational orientation. In another aspect, an apparatus for use in a pipeline is provided. The apparatus includes a body and at least one rotational control member disposed around the body and extending radially to the pipeline therearound. The rotational control member is capable of maintaining the body in a preselected rotational orientation relative to the pipeline. In yet another aspect, a measurement tool for use in a pipeline is provided.

Abstract: In the manufacture of glazing panels comprising sheets marginally bonded together, in order to simplify and speed up production, a method of effecting bonding between at least one such sheet and one or more members assembled in marginal contact therewith, comprising bringing the assembly within the sphere of treatment means which is carried by a frame and causing the treatment means to act simultaneously on each side margin of the assembly to bond it together. In an apparatus for performing the method, in order to accommodate assemblies of different sizes carried by a support, each beam of the frame is coupled at one end relative to a movable coupling, whereby the end of each beam is movable along another beam in the direction of whose length its end coupling is movable, so that the size of the frame can be adjusted.

Abstract: An apparatus for manufacturing a glazing panel which includes a pair of glazing sheets separated by an intervening marginal spacer frame formed to a required size and shape from strip material and marginally secured between the pair of sheets. The apparatus comprises a frame forming mechanism which includes guides defining at least two paths for feeding required lengths of the strip material, stops defining a position for the leading ends of the strip material as it is fed, a plurality of bending stations arranged to bend the strip material on at least one of the paths to form frame corner angles at required distances from the stops, and apparatus for joining the ends of spacer strip material which has been fed along the paths and bent, thereby to form the frame.
