Title: Laser welder for pipeline
Inventor: JONES RICHARD L
IPC: B23K26/10
Filed: 1995-01-05
Granted: 2005-09-13
Abstract: An automatic welder is used in an internal welder unit which travels along the interior of a pipeline and welds the abutting ends of the pipe segments together.      The automatic welder has a carriage assembly that contains a laser source for producing a laser beam, first and second line-up clamp assemblies for aligning the respective abutting ends of the pipe segments together, at least one laser beam conductor, or alternatively a reflecting surface positioned between said first and second line-up clamp assemblies along the axis of said beam, for directing said beam to the abutting ends of said first and second pipe segments, and a drive for rotating the reflecting surface around the axis of said beam to direct the beam to the abutting ends of said pipe segments for welding said pipe segments together. The automatic welder can also be configured as an external welder in which the automatic welder carrying a laser source is carried on a track mounted on the outside of the pipeline.      As the external welder orbits around the pipeline, the laser source generates a laser beam which is directed at the junction of the abutting ends of the pipe segments for welding them together.

Title: High power superconductive circuits and method of construction thereof
Inventor: MANSOUR RAAFAT R
IPC: H01P1/203
Filed: 1995-12-22
Granted: 1998-02-24
Abstract: A high power high temperature superconductive circuit for use in various microwave devices including filters, dielectric resonator filters, multiplexers, transmission lines, delay lines, hybrids and beam-forming networks has thin gold films deposited either on a substrate or on top of the high temperature superconductive film.  Alternatively, other metal films can be used or a plurality of dielectric films can be used or a dielectric constant gradient substrate can be used.  The use of these materials in a part or parts of a microwave circuit reduces the current density in those parts compared to the level of current density if only high temperature superconductive film is used.  This increases the power handling capability of the circuit.

Inventor: BARTHELMESS ULRICH
IPC: F16H63/30
Filed: 1996-03-15
Granted: 2001-09-18
Abstract: The invention relates to a centrifugal force separator whose rotor shaft protrudes at at least one of the two axial ends through a chamber for the discharge of the fines and the air.      Particularly, the invention relates to the problem, in a centrifugal force separator with bilateral aspiration of fines and air, of reducing the distance between the bearings of the rotor shaft, while at the same time achieving an optimum between the requirement for unhampered outlet of the fines and the separating air, on the one hand, and, on the other hand, the requirement of a short distance between the bearings and, therefore, a short, light rotor shaft. According to the invention, each outlet chamber 17,18 provides an extension 19,20 or boss reaching inward axially, in which a bearing 21,22, for the rotor shaft is contained.

Title: Method and apparatus for producing coreless rolls of sheet material
Inventor: SALZSAULER DONALD J
IPC: B65H18/26
Filed: 1998-01-23
Granted: 2006-03-28
Abstract: A roll of sheet material, such as plastic film wrap, having an inner layer wound at low tension and an outer layer wound under greater tension provides a coreless roll.  Eliminating the need for a core reduces the cost of producing rolls of sheet material, and reduces the weight and outer dimensions of the roll with a consequent reduction in shipping and storage costs. An apparatus and method for producing such a roll, from a pre-wound master roll or as part of a production lint for forming the sheet material, involves varying the longitudinal tension applied to sheet material as it is wound onto an expandable mandrel. After the roll has cured, the mandrel is collapsed and disengaged from the roll to provide a coreless roll.
