  • Patent number: 6986381
    Abstract: Molds are fabricated having a substrate of high density, high strength ultrafine grained isotropic graphite, and having a mold cavity coated with a refractory metal such as W or Re or a refractory metal carbide such as TaC or HfC. The molds may be made by making the substrate (main body) of high density, high strength ultrafine grained isotropic graphite, by, for example, isostatic or vibrational molding, machining the substrate to form the mold cavity, and coating the mold cavity with titanium carbide via either chemical deposition or plasma assisted chemical vapor deposition, magnetron sputtering or sputtering. The molds may be used to make various metallic alloys such as nickel, cobalt and iron based superalloys, stainless steel alloys, titanium alloys and titanium aluminide alloys into engineering components by melting the alloys in a vacuum or under a low partial pressure of inert gas and subsequently casting the melt in the graphite molds under vacuum or low partial pressure of inert gas.

  • Patent number: 6910071
    Abstract: A surveillance monitoring and automated reporting method is used for detecting observable changes in data sources over a network, such as the internet, for accessing changing data, such as world wide web content data, and for providing scheduled change detection notifications and results through user defined search criteria for automated monitored search criteria matches on a recurring basis by user defined scheduling. The method extracts content data from the data sources and updates a master database, then detects changes in the content data within the search criteria. Upon detection, the user is notified using graphical interfaces, electronic mail messages, pager messages, or personal data assistant messages.

  • Patent number: 6327750
    Abstract: A lace-tensioning device which is a rigid cylindrical body (64) with two passages (58, 60) aligned parallel to the cylindrical axis and a handle element (62) projecting from the body (64) perpendicular to the cylindrical axis and functioning as a lever. The device is used in a laced closure by modifying the lacing pattern from the standard alternating pattern at one of the pairs of guide elements (68, 70) of the closure and threading the lace (75) through both passages (58, 60) of the tensioning device. A segment of lace (76) from one side (82) of the closure goes through one passage (60) in the device and then back to the same side (82) of the closure from which it came. A segment of lace (78) from the opposing side (84) of the closure goes through the other passage (58) in the tensioning device and back to the same opposing side (84) from which it came. The lace (75) is otherwise laced conventionally and its ends are tied together in a secure knot.

  • Patent number: 5842697
    Abstract: The invention comprises a continuous surface made from jigsaw puzzle pieces, wherein the three or more pieces whose corners share a common point when assembled, have corner angles whose sum is less than 360 degrees with the common point as vertex of said corner angles. The present invention makes it possible to work on jigsaw puzzles which, when assembled and during assembly, form continuously curving polyhedral surfaces, and to provide a jigsaw puzzle whose pieces assemble edge to edge into a self-supporting curved surface which is a closed multifaceted polyhedron whose appearance is substantially spherical.
