Title: Support for reactor pressure vessel fixed at ducts - permits slow thermal movement from fixed point but resists sudden movements
Inventor: HARAND ELMAR
IPC: G21C13/024
Filed: 1978-02-24
Abstract: A support system for a reactor pressure vessel comprises a surrounding anti-burst device, typically a prestressed concrete biological shield, against which the pressure vessel is braced. The pressure vessel is conventionally supported in the vicinity of its outgoing ducts, so that the ducts essentially constitute a 'fixed point' from which expansion and contraction take place. At the upper and lower ends the vessel is contained by support systems which are resilient in the long-term. More specifically, these upper and lower support systems each comprise a hydraulic piston-cylinder unit acting on a holding ring bearing in turn against the end of the pressure vessel. By permitting slow movement in the resisting supports at top and bottom of the vessel, accurate accommodation of thermal movements is not required. Should a duct or vessel burst occur, the resultant forces are resisted by a virtually rigid retaiing system.

Title: Pipe bending device forming uniform wall thickness - has compacting tool with partial oblique abutting surface providing increased wall thickness
Inventor: KOENIG RUDOLF
IPC: B21J9/06
Filed: 1979-01-23
Abstract: When making pipe bends from straight pipe the wall thickness on the outside of the bend is reduced whilst the wall thickness on the inside is increased. A pipe bend of uniform wall thickness can be made by taking a straight length of pipe (2) and supporting it with a close fitting bar (1). A gas burner (6) heats the wall of the pipe, whilst it is subjected to an axial force applied through a collar (4) with a sloping end face. This force deforms the pipe so that the wall thickness is increased on one side and compensates for any deformation during bending.
