Abstract: A fluid seal assembly (the assembly) of the present invention is disposed between an outer surface, i.e. engine block or any other part that requires application of the assembly and a rotatable member, such as, for example a shaft, wherein the assembly circumscribes the shaft and lubricated the shaft and the same rotates around the axis. The assembly includes a primary seal and a wear sleeve. The primary seal includes a casing and a seal element that contacts a sealing surface on the wear sleeve. The casing includes an outer diameter and an outer seal formed onto the outer diameter. The wear sleeve has a cylindrical portion defining an inner diameter and an inner seal formed into the inner diameter of the wear sleeve. The outer and inner seals of the present invention provide improved retention in metal bores during thermal expansion and eliminate spring back effect of the assembly after installation.

Abstract: Embodiments of a translating adjacent-blast shield and method of protecting external slots of a missile from a high-temperature, high-pressure gas plume of a missile that is launched from an adjacent or nearby launcher tube of a launcher are disclosed herein. The translating adjacent-blast shield may be provided circumferentially around each of the missiles in a launcher and may cover at least portions of external slots of the missiles. The translating adjacent-blast shield may translate along the missile during launch to expose the external slots and may remain on the missile after launch.

Abstract: A method and a drug delivery system for transdermally administering parathyroid hormone (PTH) in a pulsatile fashion are provided, where the drug delivery system comprises an array of microprojections each comprising PTH.

Abstract: An applicator for a microprojection array is described. In one embodiment, the applicator comprises an energy-storing element. Application of force causes the compressed energy-storing element to extend or transition from first and second configurations, releasing stored energy to deploy a holding member in the application which is configured to hold an array of microprojections. In another embodiment, the applicator comprises an energy storing element with two stable configurations, a first stable configuration and second stable configuration. Application of force causes the energy-storing element to transition from the higher energy first stable configuration to the lower energy second stable configuration, releasing the difference in energies of the two states to deploy a holding member in the application which is configured to hold an array of microprojections.

Abstract: Workpieces are loaded into a cleaning chamber. The cleaning chamber is pressurized with a first dense-phase cleaning fluid, the temperature and pressure of the first dense-phase fluid being maintained at less than about 1500 psi using a temperature control device. The workpieces are soaked in the first dense-phase fluid for a predetermined time period. After soaking, the workpieces are further cleaned by applying a second, localized, high-pressure dense-phase fluid to the surface of the workpieces.
