Patent NL-7302449-A (NL)
Inventor: ANSCHUTZ O
IPC: B29C65/20
Filed: 1973-02-22
Abstract: The ends of thermoplastic profiles to be joined are placed into contact with a heated element so that the thermoplastic material will be softened. During this softening the outward displacement of the thermoplastic material beyond the outer contour of the respective profile is prevented. Upon softening the ends are moved out of contact with the heated element and are placed into abutment with one another. During the subsequent hardening of the softened material outward displacement beyond the outer contour of the profiles is again prevented.

Filed: 1998-08-31
Abstract: A riser tube tower for stabilizing riser tubes extending from respective wellheads associated with a seabed frame on the seabed to a platform, preferably a tension leg platform, at the sea surface. The riser tube tower includes vertical wires connecting the platform with the seabed frame. Horizontally disposed guide plates are fixed in position at one or more levels of the tower.
