摘要： Welding plates for laser beam welding of a fuel rod grid are provided, each welding plate having a surface with a set of equally spaced, parallel grooves and with a second set of such grooves perpendicular to the first set. Each of the welding plates is provided with openings therethrough at the points of intersection of the straps forming the grid, so as to expose those points of intersection to a laser beam for laser beam welding of the points of intersection. A vane side welding plate has the walls of the laser beam access openings placed so as to hold vanes extending from the straps in deflected position. Stand-off pins and clamping bolts are provided, the latter having heads with access openings for the laser beam. The welding plates are provided with protrusions which extend laterally thereof, the protrusions having precisely located holes with precision bushings therein.

摘要： Methods and systems are provided for cooling an object with a cryogen having a critical point defined by a critical-point pressure and a critical-point temperature. A pressure of the cryogen is raised above a pressure value determined to provide the cryogen at a reduced molar volume that prevents vapor lock. Thereafter, the cryogen is placed in thermal communication with the object to increase a temperature of the cryogen along a thermodynamic path that maintains the pressure greater than the critical-point pressure for a duration that the cryogen and object are in thermal communication.

摘要： Embodiments of the present invention are directed to a gas distribution system which distributes the gas more uniformly into a process chamber. In one embodiment, a gas distribution system comprises a gas ring including an outer surface and an inner surface, and a gas inlet disposed at the outer surface of the gas ring. The gas inlet is fluidicly coupled with a first channel which is disposed between the outer surface and the inner surface of the gas ring. A plurality of gas outlets are distributed over the inner surface of the gas ring, and are fluidicly coupled with a second channel which is disposed between the outer surface and the inner surface of the gas ring. A plurality of orifices are fluidicly coupled between the first channel and the second channel. The plurality of orifices are spaced from the gas inlet by a plurality of distances, and have sizes which vary with the distances from the gas inlet as measured along the first channel, such that the size of the orifice increases with an increase in the distance between the orifice and the gas inlet as measured along the first channel.

摘要： A laptop computer including a display securely attached by one or more swing arms, pivotally mounted at their opposite ends to the laptop body and the display, which allows the display to be manually elevated and rotated forward to a position over the keyboard of the computer. The swing arms are sufficient in length to allow the display to be positioned along the rear edge of the computer for normal viewing or rotated and elevated forward or upward for close-up viewing in tight viewing situations. The invention is ideal for near sighted individuals and for use in tight, restricted locations, such as an airplane seat, because the monitor can be moved upward and forward so the display screen is closer to the user and he or she can still adequately type.

摘要： A method and apparatus for forming a layer on a substrate in a process chamber during a plasma deposition process are provided. A plasma is formed in a process chamber, a process gas with precursor gases suitable for depositing the layer are flowed into the process chamber, and a magnetic field having a strength less than about 0.5 gauss is attenuated within the process chamber. Attenuation of such a magnetic field results in an improvement in the degree of process uniformity achieved during the deposition.

摘要： A suture package is designed to facilitate automated loading of multiple needles and sutures into the package. The package includes a tray, for containing the needles and sutures, and a cover. The sutures are contained in a peripheral channel of the tray and an array of resilient cantilevered fingers prevent the sutures from lifting up out of the channel. Needle parks retain the needles that are attached to the sutures. In another embodiment of the invention, a package for retaining a wound suture and attached needle includes a tray for containing the needle and suture, including cover-latching elements that each have two vertical surfaces. Tabs on the removable cover each contact a surface of a corresponding latching element and have a free element that engages a shoulder of the element.

摘要： A process for welding the adjacent ends of frame members peripherally surrounding the interleaved straps of a fuel assembly grid which includes placing the assembled grid and its frame members into a fixture made to substantially the same dimensions as the outside dimensions of the grid. The side members of the frame are arranged such that a space appears at each of the four corners and a special tool placed in each of the four corner cells of the grid is designed to have an opening which corresponds to the openings formed on each corner of the fixture. After the tooling is placed in each of the four corner cells, the assembled grid and fixture is then placed in welding apparatus such that a welding tip thereof is placed in the tool located in a corner cell. Since the opening in the tool and between the plates of the fixture and at each corner are in alignment, the welding tip accordingly moves through the openings and into contact with the overlapping ends of the frame members placed on the peripheral surface of the grid. The upper welding tip is then brought into contact with the other side of the overlapping ends and a spot weld accordingly applied to the frame member overlapping ends.
