A system which utilizes a source of ultraviolet radiation to mark a surface or to cure selectively a photosensitive paint applied to a surface. The source of UV light is either a laser or a broadband source and the light is controlled by an aperture and/or a stencil apparatus. The photosensitive paint is applied by a controlled technique as a protective or a decorative coating.

Technique for the application and cure of photosensitive paints

A two-axis optical wrist which can be used in combination with an industrial manipulator having associated therewith a laser beam delivery system. The two-axis optical wrist for laser application provides two additional degrees of freedom which in combination with a three-axis industrial manipulator provides the five degrees of freedom necessary for industrial material processing laser systems to position a laser beam anywhere within the work envelope of an industrial manipulator.

This disclosure relates to automated manufacturing apparatus and systems. The invention is provided to an integrated carousel system to provide selected end-of-arm tooling for use in a laser material processing system in a laser-robotic, work cell.

End-of-arm tooling carousel apparatus for use with a robot

A robot laser work cell combines a plurality of systems which include an orthogonal axis manipulator system, a laser beam delivery system, a safety enclosure system, a coolant chiller for the laser beam delivery system, an air filtration and drying system in communication with the laser beam delivery system, an exhaust system for removing toxic fumes from the area proximate the output of the laser beam delivery system and a variety of precision table and other fixturing means which can be used in combination to function as the work cell of this invention. In an alternative embodiment, a laser package is mounted by a modular wrist onto the Z-axis of the orthogonal axis manipulator and the laser beam delivery system.

A welding wire feeding apparatus with orbital mounting assembly for use in combination with an industrial manipulator of the type including a 'Z' axis assembly from which there is dependingly supported an extended welding axis post for rotational movement about the 'Z' axis. The improved welding wire feeding apparatus mounting assembly is rotatably mounted on the bottom of the 'Z' axis or wrist assembly of the robot and is in communication with the extended axis post by a rubber-lined yoke so that the rotational movement of the orbital welding wire feeding apparatus is simultaneous with that of the extended welding post. As a result of a support bearing and the attachment through a rubber-lined yoke, no mass or stiffness coupling occurs between the wire feeding apparatus and the extended axis post so that the natural frequencies of the extended axis post remain unchanged.

Apparatus for connecting two fluid cooled stator coils of a turbine generator electrically in series and hydraulically in parallel. A two piece combination is bolted together to securely fasten an interconnective bundle of leads in such a way as to permit assembly of the leads without interference with a nozzle used in the coolant circuit. The apparatus is utilized in pairs, one for each connected stator coil, and with one bundle of conductive leads disposed between and fastened by each of the pair of the present invention.

A dynamoelectric machine utilizing stiff, multiple component phase leads for connecting potentially misaligned stator coils and parallel phase rings. The phase leads, when attached to stator coil and phase ring coolant headers, provide electrical communication therebetween. The first and second phase lead components have a hole and cylindrical portion respectively wherein the cylindrical portion is insertable in the hole. Such phase lead hole has a longitudinal axis perpendicular to both slot elongation directions. Intimate electrical contact between the phase lead components and their connected coolant headers is insured by disposidng solder between their mateable, plane surfaces. Intimate electrical contact between the phase lead components is insured by brazing the components together at the interface between the assembled cylindrical portion and hole. Translational misalignment between the connectable phase ring and coil is accommodated in the three perpendicular directions by providing the slotted openings and permitting insertion of the cylindrical phase lead portion into the phase lead hole for selected distances. Such selective insertion is obtained by supplying extra stock to the cylindrical phase lead portion and trimming that portion to the appropriate length at assembly time.

A fluidly cooled flat plate neutral bus for electrically connecting the neutral bushings on dynamoelectric machines. The current carrying flat plate is in heat transmissive contact with a coolant carrying conduit which transfers heat generated in the neutral bus to the coolant flowing therethrough. The fluidly cooled flat plate neutral bus provides high heat flux while occupying a small volume.

Disclosed is an electrical transformer having a core and coil assembly mounted in a hollow case and a method of manufacturing the case. The hollow case has cast at least one cooling duct within it. Each cooling duct is a hollow tube, formed into a loop, with its ends brazed into a manifold. The manifold has nipples brazed into it which provide a connecting passage for the flow of coolant through the nipples into the manifold and through the tubes that have been cast within the transformer case.
