    摘要: A shield or cover combined with a collapsible core used in machines for making concrete pipe lined with a plastic liner. The cover is mounted on the outside of the core between the core and the liner and extends the full length of the seam between the stationary side and the moveable side of the core. The cover extends around the core a sufficient distance to prevent friction between the liner and the moveable portion of the core from pulling the liner out of the concrete as the core is collapsed.

    摘要: The present invention relates to reusable hollow formwork elements of elastic material which may be used for the concreting of pipelines, and which by filling with a gaseous or liquid medium, can be given compressive resistance. The invention also relates to a method of operating such formwork elements.

    摘要: A ladle lining installation embodying a relatively deep cupshaped ladle and also a collapsible pattern adapted for use in the ladle and having novel facilities for centering the same in the ladle and thereafter leveling it, together with facilities whereby it may be shrunk or collapsed after the refractory lining has been completed within the continuous arcuate space surrounding the pattern in order to break the bond between it and the lining material and thereby permit the used pattern to be readily hoisted from the lined ladle. Novel means are provided for confining the rammed refractory material in such continuous arcuate space and thus preventing it from flowing inwardly over the bottom wall of the ladle.
