Abstract: The present disclosure generally relates to the field of filtration. In particular, the present disclosure relates to filtration devices, systems and methods for high flowrates and low pressure differentials through porous bodies of metal fiber media.

Abstract: Filters that include non-horizontal filter cavities, such as cavities that are vertically, diagonally, or otherwise non-horizontally with respect to a filter block.

Abstract: Embodiments of the present invention include systems and methods for providing a filter that is sealed solely with mechanical forces. The filter may be a high pressure filter used in semiconductor manufacturing. In various embodiments, the filter includes a housing with an angled end and a filter element disposed inside the housing. The filter further includes a fluid fitting with an angled side. The angled side of the fitting has a different angle than the angled end of the housing. The filter also includes a compression collar fitted over the housing to compress the housing and the fitting. The result is a filter that may be used as a high-pressure fluid restrictor. The filter uses only mechanical seals to provide leak-proof highly filtered fluids in which impurities, contaminants and particulates are removed.

Abstract: Sintered fiber filters are provided that can afford high particle capture efficiency and/or low pressure drop during operation, and are useful in applications such as semiconductor processing. The shape of at least a portion of the individual fibers (e.g., metal fibers) used to make the filter have a three-dimensional aspect, which allows for a low packing density and high porosity filtration media. Certain filters have a cylindrical or tube-like shape with tapered ends of higher density. Methods of making such filters, for example, using axial pressing, are also described.

Abstract: Methods and systems for easily replacing fluid disbursement devices used in a sanitary bioreactor are presented. The system includes a fluid disbursement device, a tube adapter, a wand adapter. The fluid disbursement device is fixed to the tube adapter. The tube adapter and wand adapter are essentially complementary and are releasably connected. The combined fluid disbursement device and tube adapter unit is easily replaceable during the cleaning and sterilization of the bioreactor. An O-ring, located in an O-ring grove, provides an impermeable boundary between the wand adapter and the tube adapter.

Abstract: Methods and apparatus are provided for preventing clogging in impulse ink jet printers. It has been found in accordance with the invention that ink clogging during quiescent periods can be prevented by providing an ink that has the property of forming a barrier of higher viscosity ink where the ink contacts the ambient air. As a result, the viscous barrier shields the remaining ink from the effects of air exposure during the quiescent period. Thereafter, the barrier is removed by a series of sub-pulses that re-homogenize the viscosity barrier and clear the nozzle.

Abstract: The disclosed method includes the steps of positioning an ultrasonic transmitter (50, 52) on the exterior body portion (54) of the valve (14), oriented so that the transmitted ultrasonic wave intercepts the path (46) of the closure member (30) at least at one location, and positioning an ultrasonic receiver on the body portion oriented to detect reflected ultrasonic waves when the closure member passes through such location. The valve body (20) is filled with water and the closure member is caused to move along the path. The transmitter and receiver are operated to generate an output signal trace (64) commensurate with the magnitude of the ultrasonic wave reflected from the closure member at the targeted locations along the path.
