Abstract: A method for producing a pre-insulated fitting including providing a mould, wherein the mould has open end faces and an inner contour, wherein the inner contour corresponds to the fitting outer contour of a pre-insulated fitting including applying a coating to the inner contour, wherein the applied coating, after demoulding, forms the outer jacket of the pre-insulated fitting. Then, installing a fitting internally in the mould, wherein the internal fitting forms the fitting through which medium flows in the pre-insulated fitting. Closing the end faces of the mould by means of closure caps. Introducing a liquid insulating material into the cavity formed between the inner contour of the mould, the closure caps and the internal fitting, and removing the mould and the closure caps.

Abstract: An apparatus and method for manufacturing a pipe assembly having an inner pipe and an outer jacket may include a support member, a pair of lance assemblies and a pair of caps. The support member supports the outer jacket of the pipe assembly and is drivable between a first position and a second position. The pair of lance assemblies are configured to be inserted into opposing ends of the inner pipe such that the pair of lance assemblies engage an inner wall of the inner pipe. One of the outer jacket and the inner pipes moves relative to the other of the outer jacket and the inner pipe to center the inner pipe within the outer jacket when the support member is driven from the first position to the second position. Insulation is inserted through at least one cap into a space between the inner pipe and outer jacket.

Abstract: A drawing assistance system enhances a sketch drawn by a user in an electrical document on a computer system by collecting stroke data from one or more strokes of a sketch as a user draws the sketch. The stroke data includes time-based information and features of each stroke. The strokes are handled based on the time-based information, and analysed based on the strokes handled based on the time-based information. The sketch is enhanced based on results of the analysis.
