A seal ring of a shaft seal has micro-topography depth features, such as wavy faces or radial grooves, formed in the seal face which define a hydrodynamic seal region between opposing seal faces. The micro-topography depth features are formed by an excimer laser shaped such that the beam shape at least has non-linear side edges which define convergent side areas of the beam. The convergent side areas are defined by side edge sections which converge toward each other and preferably are non-linear. For example, the beam shape may be circular or elliptical. The laser beam first cuts repeatedly along the same beam path to define a cut with an increasing depth, whereby the laser beam is shifted incrementally sidewardly to define multiple adjacent beam cuts that form the micro-topography feature such as a valley of a wavy face, a radial groove or the like. As the laser beam cuts adjacent parallel grooves, sidewardly adjacent beam passes overlap one with each other and blend the edges of the sidewardly adjacent grooves together. The method of the invention provides micro-topography depth features that are precisely and accurately defined to improve performance of the seal ring.

A turbine bucket includes a bucket airfoil having a tip shroud with a leading edge comprising two scalloped faces and a trailing edge comprising a third scalloped face defining leading and trailing edge profiles substantially in accordance with Cartesian coordinate values of X and Y as points 1-41 set forth in Table I. The X and Y values are distances in inches which, when respective points are connected by smooth, continuing arcs define the leading and trailing edge tip shroud scalloped profiles. The tip shroud further has first and second, upper and lower, Z form edge profiles substantially in accordance with Cartesian coordinate values of X and Y as points 42-59 and 60-77, respectively of Table II.

The disclosure provides compositions and methods for making a colorized solution of an aqueous disinfectant that is both stable in bulk solution and will fade to clear within a predetermined period of time after being applied to a surface, for example as a spray or film. The compositions and methods described here allow an end user to visualize both the extent of coverage and the duration of contact of the disinfectant with the surface, thereby providing more efficient disinfection of the surface.

An asset tracking system includes one or more RFID readers and one or more RFID tags cooperating with the readers, and at least one garment, wherein the readers each include an RF wideband transceiver and a linearly polarized antenna. Each reader polls periodically a corresponding one or more RFID tag to determine a distance of a particular tag from each reader. Each reader computes the tag's distance in real-time and updates a corresponding database in real-time for an on-demand reaction as determined by a processor in each reader. Each tag includes a wideband transceiver and an antenna array. The antenna array is implanted on each garment and ensures a spherical coverage around each tag. The antenna array includes two or more patch antenna distributed around each garment so as to provide full 360 degree and spherical coverage around each garment, and wherein each patch antenna is provided on a dielectric. Coverage is thereby provided by the patch antenna array and removes the need of having a single line of sight. Each tag may include an on-board processor adapted to adaptively switch between the antennas in the antenna array so as to select an appropriate antenna of the array for a signal from a corresponding reader.

A heat pipe assembly (10/110), under vacuum and having a working substance charged therein, comprising generally an evaporator (12/112) adapted to evaporate the working fluid and a condenser (16/116). The heat exchanging condenser is in fluid flow communication with the evaporator. The condenser is adapted to condense evaporated working substance received from the evaporator and has a reservoir (30/130), located at a higher elevation than the evaporator, for collecting liquid working fluid therein.
