04/25/13 - 20130098881 - Arc evaporation source having fast film-forming speed, coating film manufacturing method and film formation apparatus using the arc evaporation source
An arc evaporation source having fast film-forming speed includes: at least one circumference magnet surrounding the circumference of a target, wherein the magnetization direction of the magnet runs orthogonal to the target surface; a non-ring shaped first permanent magnet on the target's rear surface side has a polarity in the...

04/18/13 - 20130092665 - Arc guiding, gripping and sealing device for a magnetically impelled butt welding rig
A magnetically impelled arc butt (MIAB) welding device positioned on the rig floor heats facing ends of a pair of wellbore tubulars. After the facing ends are heated and/or melted, a force application device compressively engages the facing ends to form a welded joint....

03/07/13 - 20130056447 - Automation of reaction metallurgical joining for copper conductors
Copper conductor members or other copper-based workpieces are welded using a suitable copper alloy material that is reactive with the joining surfaces of the copper members. The reactive metal material may be applied as a thin metal foil strip between assembled facing joining surfaces. The members are pressed together against...

02/14/13 - 20130037526 - Automatic repair of electric circuits
An apparatus and method for automatically inspecting and repairing printed circuit boards includes an inspection functionality automatically inspecting printed circuit boards and providing a machine readable indication of regions thereon requiring repair. An automatic repair functionality employs the machine readable indication to repair the printed circuit boards at some of...

05/31/12 - 20120132625 - Forming of metallic glass by rapid capacitor discharge forging
A forging apparatus and method of uniformly heating, rheologically softening, and thermoplastically forming metallic glasses rapidly into a net shape using a rapid capacitor discharge forming (RCDF) tool are provided. The RCDF method utilizes the discharge of electrical energy stored in a capacitor to uniformly and rapidly heat a sample...

03/08/12 - 20120055905 - method of smoothing and/or bevelling an edge of a substrate
The present invention relates to a method of smoothing and/or bevelling an edge of a substrate. The present invention also relates to a substrate produced by the method according to the present invention, in particular a substrate having an edge smoothed and/or bevelled by the method according to the present...

12/22/11 - 20110309056 - Apparatus and method for arc calibration of fusion splicers
A method of calibrating a fusion splicer, including: heating ends of a first and second fiber with an arc; measuring fiber end melt-back at a corner of the first fiber and a corner of the second fiber; increasing the heat of the arc and heating the ends of the first...

05/19/11 - 20110114609 - Method and device for forming the welding wire end
The invention relates to a method for forming an end of a welding wire (13) having a defined material and a defined diameter for a threading procedure, wherein the welding wire (13) is delivered from a wire storage via at least one wire core (12) through a contact tube arranged...
