摘要： An improved tool for locking a band clamp, and an improved lock for a band clamp is disclosed. The tool includes a knife body having a knife edge that progressively cuts the free end of the band over a period of time, rather than simultaneously cutting the entire band width. In one embodiment, this is accomplished with a knife edge that is non-linear. The tool further includes a punch with a rounded or hemispherical shaped leading tip that forms an improved locking dimple. The locking dimple forms an improved lock having side walls that are, at least in part, parallel with the walls of the surrounding aperture in the band. By varying the profile of the knife edge, the punch can more fully form an improved locking dimple.

摘要： A burst disk assembly relies on a brittle material as the burst disk. Conventional manufacturing tolerances are suitable with the mounting assembly. Flatness and collinearly are achieved by an alignment adapter interfacing between an anvil and the burst disk, on the low-pressure side thereof. A seal, typically thinner than the alignment adapter, is held against the high-pressure side face of the burst disk by a pilot or loader face. All materials are ultra-pure, high-temperature tolerant, and non-reactive. Thin films over metal are not used. Reliable, repeatable, predicable burst pressures have been achieved without resort to highly specialized manufacturing processes. Ceramics and crystalline materials may serve as a burst disk, and quartz has been shown effective. Various grades of fluorocarbon materials have been found to provide suitable coatings, fixtures, and seals. Expanded polytetrafluoroethylene forms a suitable seal. Slightly expanded PTFE such as that sold under the brand-name "Gylon.TM." has provided suitable alignment adapters.

摘要： A pump for ultra-pure fluids comprises a flexible diaphragm separating a fluid chamber from an air chamber. The diaphragm creates an airtight seal between the fluid chamber and the air chamber when a self-centering and trapezoidal shaped wedge compressively forces the diaphragm into a trapezoidal shaped perimeter cavity surrounding the chambers. Any leak from the fluid chamber into the air chamber is detected by a fiber optic system comprising two optical fibers that are disposed at an angle that is calculated to enable light to pass between the fibers only in the presence of a liquid having a predetermined index of refraction. The fiber optic system can also be used to determine the stroke of the pump by disposing the fiber optic lines at an angle calculated to reflect light off of the oscillating diaphragm when the diaphragm arrives at a predetermined location.

摘要： A pump for ultra-pure fluids, such as hot, de-ionized water, processing acids, and the like, such as those used in the semiconductor processing industries, is designed to operate at greater than 10 and often 30 or 50 million cycles without failure, and to be failclean. A diaphragm pump maintains a free diaphragm, supported in a contoured chamber for driving and being driven by a piston, able to move radially, rather than absorbing misalignment or distortions. A self-energizing, self-centering, trapezoidal seal captures a constant-thickness diaphragm between a head and body forming the chamber of the pump, separating a body portion and a head portion. An oriented, calendered, multi-layered chlorofluorocarbon diaphragm may be the same material chemically as the body, head, or both. Non-reactive pilots control an operating (motive) fluid, detecting the end-of-stroke whether near the head or near the body. An integrated base controller for the operating fluid supports the apparatus, has a quick exhaust for dumping external-controller air overboard after use, and a bias disk to provide precise, digital, spool positioning within an operational range of pressure differentials. The heads may connect to the body by slip rings, so heads remain registered. Cantilevered portions of the head may absorb secondary creep and provide continued spring loading using exclusively non-reactive materials, no metals, and no elastomers, as a failclean system.
