Patent number: 8229696Abstract: According to one embodiment of the invention, a method for preventing the failure of a system, which includes one or more pipes, or one or more cooling jackets, or one or more fluid cooled system components carrying a fluid, involves detecting one or more pressure levels of the fluid in the one or more pipes at one or more points, then comparing the detected pressure levels to a corresponding one or more predetermined limitation values. If the detected pressure levels exceed the corresponding limitation values, a shut-down signal is generated. The shut-down signal triggers the adjusting of one or more systems responsible for causing thermal variations of the fluid, preventing the system from failing while allowing the system to continue operation shortly thereafter.Type: GrantFiled: September 19, 2011Date of Patent: July 24, 2012Assignee: Titanium Metals CorporationInventor: Lawrence M. Rubin

Publication number: 20120165973Abstract: A method for qualifying an automated process for inspecting and sorting particles through the production and use of seed particles is disclosed. In one embodiment, seed particles are produced by forming a conformal surface layer on a plurality of particles, thereby imparting them with at least one property whose value or range of values is the same as or about the same as a value or range of values of a corresponding property of undesirable particles. By introducing a predetermined quantity of seed particles, their detection and removal by the automated sorting system can be used to periodically calibrate and qualify the sorting system without interrupting the manufacturing operations or introducing actual undesirable particles into the process stream. The production and use of seed particles to qualify an automated sorting system is particularly well-suited for use with Ti sponge sorting operations.Type: ApplicationFiled: December 22, 2010Publication date: June 28, 2012Applicant: TITANIUM METALS CORPORATIONInventor: Matthew R. Earlam
