摘要： A thrust bearing assembly comprising a bearing runner and a bearing carrier, the carrier defining a plurality of thrust pad sites annularly around the carrier, with a thrust pad disposed at a site and with the carrier limiting movement of the thrust pad in a direction generally radial to the longitudinal axis of the runner while allowing the thrust pad to move in a direction generally parallel to the longitudinal axis. Though the range of movement is limited, the pads can tilt under load to form a hydrodynamic wedge as is known in the art. An embodiment comprises a bearing runner having a wear resistant face and a bearing carrier defining thrust pad sites disposed annularly around the carrier. In one implementation, at each site, a deflection element (e.g., Belleville washer) is disposed in a cavity and a pad is disposed over the deflection element. The pad can be at least partially disposed within the cavity. The wear resistant face contacts the pad. Another embodiment rigidly connects pads disposed oil opposite sides of a stationary bearing carrier. Another embodiment attaches pads to a bearing carrier using pad holder assemblies.

摘要： A method and apparatus for shaping the radial surface of a roller or other cylindrically shaped part in a single cycle. The preferred embodiment forms a crown geometry on one roller at a time using a CNC system to control a grinding surface in three axes. The grinding surface is controlled in two linear orthogonal directions (x and y) and around a circular axis (c) through corresponding stepper motors. In addition, the axial pressure applied by the grinding surface of the radial surface of the roller is controlled by an air pressure programmable regulator acting through a pneumatic cylinder. These four individually controlled, precise degrees of motion of the grinding surface, operating with a single rotating roller, permits extremely accurate crown shaping. The shaping is, in fact, so precisely controlled and so accurate that only one “cycle” of the grinding surface against the roller is required to achieve the desired crown profile.

摘要： A method is disclosed of fully densifying a plurality of preformed ceramic plates by axial compression of the billets along a wall defining a cylinder and cavity. A series of the plates are stacked along the wall with the smallest dimension of the billets aligned with the axis of the cavity. The billets have a ratio of the smallest dimension to the largest dimension in the range of 1:3 to 1:40. The largest dimension of each of the plates is less than the lateral dimension of the cavity to leave an annular space; the space is filled with a pseudo isostatic pressing medium. The assembly is hot pressed under sufficient pressure and heat to convert the plates to billets of substantially full density.

摘要： A method of storing nuclear fuel is described. In some cases, the method includes submerging at least a portion of a nuclear fuel rod in a storage pool containing an aqueous solution including at least one of polyhedral boron hydride anions or carborane anions. In some cases, the method includes adding a salt having a polyhedral boron hydride anion or carborane anion to a storage pool containing water and at least a portion of a nuclear fuel rod submerged in it. The method may include both of these. A storage pool is also described. The storage pool includes an aqueous solution having at least one of polyhedral boron hydride anions or carborane anions with at least a portion of a nuclear fuel rod submerged in the aqueous solution. A method of servicing a nuclear reactor core is also described.
