摘要： A thin electrical insulating coating and method for application is provided for a copper surface. The electrical insulating coating includes a bond coat layer of titanium, nickel, or NiCrAlY forming a metallurgical bond with the copper surface and an insulating layer of alumina or tantala applied to the bond coat layer. An insulating layer does not firmly adhere to copper under harsh environmental conditions such as an electroslag refining process when applied directly to the copper. However, when bond coat layer is applied between the copper and the insulating layer, it forms a strong bond adhering bond for the harsh environment.

摘要： The introduction of spray formed metals into critical applications in the aircraft engine and power generation industries has been hampered by the possibility of erosion of oxide particles from a crucible lining or pouring nozzle in conventional spray forming equipment. These oxide particles may become inclusions that limit low-cycle fatigue life of parts. Use of a cold-walled induction guide (CIG) with an electrical insulation layer between copper CIG elements and the liquid metal offers a means of delivering ceramic-free alloys to a spray system with improved efficiency. CIG design options facilitated by a new oven-brazed fabrication technique resolve induction coil environmental isolation issues, correct thermal strain tolerance problems, facilitate dual frequency induction designs, allow improved electrical coupling efficiency and thermal efficiency, result in improved melt flow initiation, and facilitate disassembly without damage from the solidified melt.

摘要： An apparatus and method for atomizing liquid metal are disclosed. A liquid metal supply is coupled to a nozzle for atomizing a stream of liquid metal in an atomizing zone extending from the nozzle. A viewing instrument provides a field of view extending to the atomization zone. A sensor coupled with the viewing instrument generates an image of the atomizing zone, and a control adjusts a flow rate of the stream responsive to the image.

摘要： A refrigerator evaporator is formed in a spread serpentine configuration having a plurality of straight tube segments and a plurality of bent tube segments where each one of the straight tube segments is joined at an acute angle to at least one other straight tube segment. The straight tube segments are arranged in a number of planar rows which are adjacent and parallel to one another. Approximately 25-50 percent of the cross-sectional area of the evaporator is not occupied by tubing or any attached fins. A cross flow blower disposed at one end of the evaporator draws air longitudinally over the evaporator.

摘要： A nozzle for atomizing molten metal to provide a powder having improved yield of fine particles is disclosed. The nozzle is comprised of a gas plenum, a melt delivery tube, and an annular inner wall means within the gas plenum for delivering atomizing gas to the exit orifice of the melt delivery tube. The exit orifice of the melt delivery tube has a ratio of inside diameter to outside diameter that provides a reduced flow of liquid through the tube during atomization.

摘要： A vent tube which is particularly useful for horizontal cryostat penetration comprises a plurality of conduit sections joined by mating rings which facilitate the incorporation of relatively deep circumferential grooves in the conduit sections. Thermal contact springs, preferably in the form of a single strip are disposed in these circumferential grooves so as to provide a means for transfer of thermal energy from the cryostat interior to the exterior either for general refrigeration requirements or for liquefaction of coolant vapor which may have boiled off from the cryostat interior. The cryostat which incorporates the present invention is particularly useful in housing NMR medical diagnostic imaging magnet and coil systems.

摘要： An apparatus, system and method for viewing an industrial process in an obscuring environment, such as molten metal atomization, is disclosed. An enclosure defining a chamber for containing a particulate form from atomized liquid metal has a nozzle for atomizing liquid metal mounted thereon in communication with the chamber whereby particles recirculate throughout the chamber. The nozzle being comprised of a cylindrical plenum means and a melt guide tube extending axially therethrough to an exit orifice. The plenum means is configured to provide a jet of atomizing gas converging in an atomizing zone extending from the exit orifice. A viewing means extends through the enclosure to a viewing orifice adjacent the atomization zone, the viewing means being configured to extend a field of view through the chamber to the atomization zone. A purging gas flow is provided in the viewing means to minimize atomized particles from contacting the window, and an image of the atomization zone is generated by viewing through the window.
