Patent number: 7449336Abstract: A method for testing for the presence of sol-gel on an aluminum test specimen includes: preparing an ammonium molybdate solution; preparing a hydrochloric acid solution; and mixing the solutions in 2:1 ratio in each of a number of receptacles. A test specimen of unknown coating, a first control specimen, and a second control specimen are placed in the mixed solution in three receptacles. The first control specimen has a sol-gel coating over an alodine coating; and the second control specimen has an alodine only coating. By timing events such as a change in color of the test and control specimens or the solution becoming opaque, the method determines that the test specimen of unknown coating has a like coating to that of a particular one of the control specimens if the timing of the event of the test specimen and the timing of the event of the particular control specimen are comparable.Type: GrantFiled: January 20, 2004Date of Patent: November 11, 2008Assignee: The Boeing CompanyInventors: Terry C.

Publication number: 20080275545Abstract: The invention relates to a method and device for the investigation of sludge deposition on materials for coating endoprostheses. At least one endoprosthesis is placed in an incubation chamber which is at least partly filled with infected bile. The incubation chamber is rocked gently on a rocking platform for a period of about 35 days. The bile fluid is regularly partly exchanged. The endoprosthesis is embodied in a coated plastic. The coating comprises 70 to 80% by weight of hydrophobic components and 30% to 20% by weight of hydrophilic components. The coating may particularly have a sol-gel embodiment. An application in bile duct prostheses is possible.Type: ApplicationFiled: May 17, 2005Publication date: November 6, 2008Inventors: Uwe Seitz, Uwe Wienhold, Carsten Grosse

Patent number: 7399635Abstract: The present invention provides an impurity measuring method comprising the steps of dropping a drop of a first solution on the surface of a substrate to be measured, moving the drop dropped on the surface of the substrate so that the drop is kept in contact with the surface and collects an impurity absorbed on the surface, recovering the drop after the movement and analyzing the recovered drop by chemical analysis to determine the type and concentration of the impurity, characterized in that the first solution is phobic to the substrate and the substrate consists substantially of Ge. The method is of particular importance for measuring metallic contamination on the surface of Ge substrates.Type: GrantFiled: December 10, 2004Date of Patent: July 15, 2008Assignees: Interuniversitair Microelektronica Centrum (IMEC), UMICORE N.V.Inventors: David Hellin, Ivo Teerlinck, Jan Van Steenbergen

Patent number: 7361313Abstract: The methods, systems 400 and apparatus disclosed herein concern metal 150 impregnated porous substrates 110, 210. Certain embodiments of the invention concern methods for producing metal-coated porous silicon substrates 110, 210 that exhibit greatly improved uniformity and depth of penetration of metal 150 deposition. The increased uniformity and depth allow improved and more reproducible Raman detection of analytes. In exemplary embodiments of the invention, the methods may comprise oxidation of porous silicon 110, immersion in a metal salt solution 130, drying and thermal decomposition of the metal salt 140 to form a metal deposit 150. In other exemplary embodiments of the invention, the methods may comprise microfluidic impregnation of porous silicon substrates 210 with one or more metal salt solutions 130. Other embodiments of the invention concern apparatus and/or systems 400 for Raman detection of analytes, comprising metal-coated porous silicon substrates 110, 210 prepared by the disclosed methods.Type: GrantFiled: February 18, 2003Date of Patent: April 22, 2008Assignee: Intel CorporationInventors: Selena Chan, Sunghoon Kwon, Narayan Sundararajan

Patent number: 7148066Abstract: Systems and methods providing for the introduction of a dye, particularly a xanthene dye, and more particularly a rhodamine dye, to liquid anhydrous ammonia to discourage theft of the anhydrous ammonia and provide for leak detection in storage vessels. The dye will stain objects which come into contact with the liquid anhydrous ammonia allowing for the detection of such contact. Generally, the staining will be visible to the naked eye, but may also fluoresce when exposed to a particular light source such as ultra violet (UV) light.Type: GrantFiled: August 2, 2004Date of Patent: December 12, 2006Assignee: GloTell Products, Inc.Inventors: Tim Bickett, Frank Eiter
