Patent number: 7415937Abstract: An actuator that at least inhibits the deleterious effects of corrosive fluids, such as seawater, does not rely on relatively expensive materials, and is capable of operation and relatively high pressures includes two sealed buffer chambers. One buffer chamber is supplied with a buffer fluid, and the other buffer chamber is maintained at a vacuum pressure. The buffer fluid in the first buffer chamber helps remove any residual corrosive fluid that may remain on the actuator translation member as it moves into the actuator housing, and any fluid that leaks into the second chamber will boil as a result of the vacuum pressure therein.Type: GrantFiled: October 27, 2006Date of Patent: August 26, 2008Assignee: Honeywell International Inc.Inventors: William L.

Publication number: 20080003099Abstract: A system includes a case, a stator, a ring seal, and a rotor and is configured to pump air out of a housing. The case is mounted on the housing. The stator is mounted within the case and has two sides, an inner diameter and an outer diameter, where the first side faces the case. The ring seal is disposed between the stator first side and the case. The rotor is mounted on a shaft and has a side facing the stator first side. The rotor side has grooves, an inner and outer peripheral surfaces, and is configured to pump air from the outer peripheral surface to the inner peripheral surface to thereby pump air out of the housing. The stator inner diameter is configured and the ring seal is positioned such that separation forces are substantially equal to or less than closing forces during a system breach.Type: ApplicationFiled: June 30, 2006Publication date: January 3, 2008Inventors: William L.

Patent number: 7226671Abstract: A method for making aerospace face seal rotors reinforced by rhenium metal, alloy, or composite in combination with silicon carbide or other ceramic. The resulting rotor also is disclosed. Ceramic grains, preferably silicon carbide (SiC), are mixed with powdered metallic (PM) binder that may be based on a refractory metal, preferably rhenium. The mixture is applied to a rotor substrate. The combined ceramic-metal powder mixture is heated to sintering temperature under pressure to enable fusion of the ceramic in the resulting metal-based substrate. A load may then be applied under an elevated temperature. The resulting coated rotor can exhibit high hot hardness, increased durability and/or high hot wear resistance, as well as high thermal conductivity.Type: GrantFiled: March 9, 2005Date of Patent: June 5, 2007Assignee: Honeywell International, Inc.Inventors: William L. Giesler, Robbie J. Adams
