Patent number: 7828299Abstract: Systems and methods associated with a fluid-activated shaft seal are provided. The systems, which feature multiple components, include a support component defining an exterior surface, a carrier component including an interior surface to slideably engage the exterior surface of the support component, and a seal disposed relative to the carrier component. The seal includes a lip portion and a fluid-responsive gel material that expands when exposed to a fluid to urge the lip portion towards or into contact with a shaft. The gel material contracts in the absence of the fluid to form or increase the size of a gap between the shaft and the lip portion. Methods of assembling and installing such a system are also described.Type: GrantFiled: June 6, 2008Date of Patent: November 9, 2010Assignee: MIDE Technology CorporationInventors: Marthinus van Schoor, David Gilbert, Andrew Cutler, Steven Klepper

Patent number: 7686308Abstract: Systems and methods associated with a fluid-activated shaft seal are provided. The system includes a housing and a seal disposed relative to the housing. The method reduces flow of a fluid between the shaft and the housing. The method involves installing the housing in an opening relative to the shaft and locating the seal relative to the housing. The seal includes a gel material that expands when exposed to a fluid. The seal reduces flow of the fluid through a gap between the housing and the shaft. Advantages of the system and method include reduced wear to the seal due to friction because the seal does not engage the shaft in the absence of a fluid. The seal engages the shaft in the presence of a fluid. Sealing quality is improved by increasing the pressure differential acting on the gel material. In some embodiments, the seal includes a lip portion.Type: GrantFiled: November 22, 2005Date of Patent: March 30, 2010Assignee: MIDE Technology CorporationInventor: Marthinus C. Van Schoor

Patent number: 7205707Abstract: Laser beam machining is applied to form arbitrarily shaped electroactive ceramics for transducers (e.g., electromechanical sensors and actuators). One particularly preferred embodiment of the invention comprises machining parallel grooves in a ceramic plate to improve flexibility. The grooves provide strain relief in bending by relieving Poisson strains transverse to the direction of bending. This embodiment offers the further benefit that planar anisotropy or directionality is introduced in the transducer. The machining process of the invention further enables the production of more complex geometries than those currently known in the art. Because of the flexibility of the machining process, virtually any desired transducer shape may be produced.Type: GrantFiled: May 26, 2005Date of Patent: April 17, 2007Assignee: Mide Technology CorporationInventors: Brett P. Masters, John P. Rodgers, Marthinus C. van Schoor
