Title: Pipe connection for bridging angular and axial misalignment - has compressible lipped seal ring to provide flexibility in rigid pipeline
Inventor: KOJIMA NORIATSU
IPC: F16L21/04
Filed: 1974-11-18
Abstract: To overcome the problems of misalignment or heat expansion when connecting rigid pipe lines, a telescopic fitting with an elastic sealing element is used. A flanged sleeve has an internal thread on one end into which a tubular fitting body is screwed. Its internal dia. is larger than the pipes which are being connected thus allowing them to enter the fitting if heat expands the length of the pipeline. A tapered sleeve connects the tubular fitting body with the end of the second pipe line. A lipped seal ring is trapped between the flanged sleeve and the clamp ring. Since the seal ring is elastic, some angular misalignment between pipe line and fitting can be overcome. To compensate axial misalignment, eccentric flanged sleeves on either end of the tubular fitting body are used.

Title: Welded joint - for fixing thermoplastic tubes to a transverse panel for automated production of (polyethylene) heat exchangers
Inventor: BUERGEL HEINZ
IPC: B29B13/02
Filed: 1975-01-21
Abstract: Ends of thermoplastic tubes are fixed into a transverse supporting plaque by providing the holes through the plaque with a conical mouth, using a heated block to soften the end of the tube from both the external and internal surfaces, and then using a shaped or inflatable mandrel to reshape the tube end to fit and weld with the mouth of the hole through the plaque. The heating block has a core mandrel of slightly smaller o.d. than the i.d. of the tube, extending within the tube to >= twice the depth of the conical mouth. The skirt of the heating block is ahped to heat the conical mouth and the corresp. outer surface of the tube simultaneously. Method is suitable for mfr. of heat exchangers etc., esp. using crystalline matls., viz polyethylene. Method provides a positively anchored bond without creating any flash or weld lip on the face of the plaque. The procedure is readily automated. Application of heat to both faces of the tube end and the adjacent region of the tube reduces thermal shock and gradient effects in the material. Weld pressure is applied evenly over a substantial proportion of the weld area.

Title: Telescopic suction tubes for vacuum cleaner - are locked by coaxial friction ring wedges to prevent tubes being pulled out
IPC: F16L27/12
Filed: 1976-04-24
Abstract: A suction tube assembly for a vacuum cleaner has a friction ring (10) located between the inner and outer tube (11, 12). The friction ring which is made from plastic is attached to the inner tube by means of a rivet (13). The two tubes can thus be axially moved to each other. A flat (16) on the outside diameter of the friction ring (10) and a similar flat on the outer tube (12) are separated by a small radial gap. In order to lock the two tubes together, they have to be twisted agains each other. This causes the corner (18) on the friction ring flat to wedge itself against the outer tube.
