Abstract: Apparatuses for controlling fluid flow are important components for delivering process fluids for semiconductor fabrication. These apparatuses for controlling fluid flow require a variety of fluid flow components which are tightly packaged within the apparatuses for controlling flow. Servicing the apparatuses requires specialized equipment and methods which enable installation of seals in close quarters in apparatuses which are installed in the field. Seal retainers may be used to retain the seals during assembly of fluid flow components into apparatus for controlling flow.

Abstract: Apparatuses for controlling fluid flow are important components for delivering process fluids for semiconductor fabrication. These apparatuses for controlling fluid flow are formed with a variety of fluid flow components, including fluid flow components for measuring various properties of process fluids. Fluid flow components for measuring may be constructed to monitor properties such as temperature and pressure, and may do so via sensing elements which also serve to enclose a portion of a flow path within the fluid flow component.

Abstract: Apparatuses for controlling fluid flow are important components for delivering process fluids for semiconductor fabrication. These apparatuses for controlling fluid flow frequently rely on large numbers of fitting assemblies. Fitting assemblies often require tight tolerances, requiring expensive manufacturing processes. Fitting assemblies formed as multiple components can reduce manufacturing costs. Fitting assemblies may be formed of a housing having an insert receiving cavity and an insert having a port, a seal cavity, and a tube stub. A flow path extends from the port to the tube stub to enable flow of fluid therebetween.

Abstract: Apparatuses for controlling fluid flow are important components for delivering process fluids for semiconductor fabrication. These apparatuses for controlling fluid flow frequently rely on valves which can provide flows at different rates and in a minimally turbulent manner. In one embodiment, a valve assembly is disclosed, the valve assembly having a valve body, a closure member, a seat, and a radial flow guide. The radial flow guide has a plurality of flow passages. The closure member has a needle, the needle having a plurality of grooves therein. The resulting valve assembly enables improved control of fluid and reduces turbulence in the resultant flow.

Abstract: A method, useful for wastewater liquid level indication rods in wastewater treatment facilities, of correcting the readings from the rod's electrode based liquid level sensors for inaccuracies and distortions caused by fat, oil, and grease (FOG) contaminant build up. The method may also detect how the electrical signals change as the liquid levels progress ever higher above the level of the measuring electrode of interest. These methods allow for the creation of improved wastewater liquid monitoring systems and management systems that can warn when cleaning is needed, help prevent pump burnout, overflow, and address other common wastewater management problems.

Abstract: Multi-layer solar control films composed of metal oxide, oxynitride, carbide, and/or oxycarbide layers are deposited on a substrate by atmospheric pressure chemical vapor deposition (APCVD). The film layers have alternating high/low refractive index. The coated substrate reflects near infrared (NIR) radiation, while transmitting a high level of visible radiation.

Abstract: This invention relates to methods and compositions for the separation of biomolecules using capillary electrophoresis with high conductivity sieving matrices. These methods and compositions are particularly useful to increase readlength and migrational speed.
