摘要： A brazed X-ray target includes a metallic cap and a graphite back including a nonlinear record groove attached thereto along a stepped surface. An upper corner joint of the stepped surface is distanced from a cap outer edge and a focal track where the maximum heat is generated during use of the target. The graphite back is extended outward toward the cap outer edge to increase a thermal storage of the graphite, and a recess is formed into the cap to maintain a selected moment of inertia of the target and thereby maintain the rotordynamics of a given X-ray tube.

摘要： A fuel cell system which includes a fuel distribution structure that uniformly distributes vaporizing fuel to a fuel cell is provided. As the fuel travels in a flow field channel in the fuel distribution structure, it is substantially converted to a vapor by the heat of the fuel cell operation in such a manner that the resulting vapor pressure works to substantially uniformly distribute fuel evenly outwardly across substantially the entire active area of the anode aspect of one or more membrane electrode assemblies in the system, and whereby localized, uneven “hot spots” of fuel at the anode aspects are substantially prevented. A pair of enthalpy exchanger and heat spreader assemblies include a cathode current collector element that also has a heat spreader plate that collects and redirects heat in the fuel cell system, the assembly acting to manage the heat, temperature and condensation in the fuel cell system.

摘要： A spring assembly for use with a direct oxidation fuel cell system is provided. The spring assembly includes a pair of spring elements, placed over each of the major dimensions of the fuel cell, such that the top and bottom spring elements provide at least a portion of the load to the fuel cell for the required compression. The springs are designed to be fully compressed under the design pressure and are held in the compressed state by two side clamps thus providing a uniform planar pressure distribution across the fuel cell system. The spring elements each include several grooves formed therein extending towards center of the element. The side clamps include fastening members which are fingerlike extensions that fit within the grooves of the spring elements to hold the springs in tight engagement over the fuel cell system, with out bolts, pins or other fasteners.

摘要： A cylindrical magnet assembly for use in magnetic resonance imaging apparatus has a radially compact construction which eliminates prior manufacturing steps. Recesses are formed in insulation layers for receiving complimentary shaped bus bars. Because the bus bars are dimensioned to fit flush within the recesses, they do not add to the radial growth of the magnet assembly.

摘要： A combustor/transition piece for a gas turbine including a double walled structure having a plurality of cooling channels, both axially and, in some cases, circumferential cross-flow passages positioned between the structure's inner member and the outer member to provide cooling air thereto, are formed in the area between the inner member of the combustor and the outer member thereof. The passages preferably extend both axially and circumferentially with respect to the direction of flow through the combustor/transition piece. The axial passages extend completely from one end to the other and the circumferential passages extend around the circumference of the combustor/transition piece. The addition of a circumferential cross-flow passage connecting axial flow coolant passages in double wall turbine components can prevent combustor/transition piece part failure due to axial passage inlet blockage without affecting normal, unblocked cooling. Double wall cooling structures are constructed using two unbonded members. The inner member is machined to form cooling passages. Differential thermal expansion (expansion of the outside diameter of the hot inner wall until contact is established with the inside diameter of the cooler outer wall) keeps the cylinders held tightly together. Double wall cooling structures are also constructed using two members shrink-fitted and then bonded together such as by welding. The inner member is machined to form the cooling passages. The improved thermal contact between the outer and inner members due to the joint reduces the thermally induced stresses in the two members.
摘要翻译：一种用于燃气轮机的燃烧器/过渡件，包括具有多个冷却通道的双层壁结构，轴向和在一些情况下，定位在结构的内部构件和外部构件之间的周向横流通道，以向其提供冷却空气，形成在燃烧器的内部构件和其外部构件之间的区域中。通道优选地相对于通过燃烧器/过渡件的流动方向轴向地和周向地延伸。轴向通道从一端到另一端完全延伸，周向通道围绕燃烧器/过渡件的圆周延伸。在双壁涡轮机部件中添加连接轴流式冷却剂通道的周向横流通道可以防止由于轴向通道入口堵塞而导致的燃烧器/过渡件部件故障而不影响正常的，未阻塞的冷却。双壁冷却结构使用两个无粘结构件构成。内部构件被加工以形成冷却通道。不同的热膨胀（热内壁的外径直到与较冷的外壁的内径形成接触为止）的膨胀使气缸紧紧地保持在一起。双壁冷却结构也使用两个收缩配合的构件构成，然后通过焊接结合在一起。内部构件被加工以形成冷却通道。由于接头而导致的外部和内部构件之间的热接触改善了两个构件中的热诱导应力。
