Abstract: Durable asymmetric composite membranes consisting essentially of a film of cross-linked sulfonated poly(ether ether ketone) adhered to a sheet of hydrophilicitized microporous poly(ethylene) are disclosed. The membranes have application in the recovery of water from feed streams where the ability to clean in situ is desirable, for example in dairy processing. Methods of preparing cross-linked sulfonated poly(ether ether ketone) suitable for use as the rejection layer and hydrophilicitized sheets of microporous poly(ethylene) suitable for use as the support layer of such membranes are also disclosed.

Abstract: The present disclosure relates to an apparatus and an apparatus assembly for assessing the suitability of a membrane, such as an osmotic membrane in an osmotic process. Furthermore, the apparatus, and apparatus assembly provide the means to optimise the parameters of an osmotic process, including the ability to gather key data for different membrane based osmotic systems to enable osmotic process and system optimisation.

Abstract: A liquid metal socket test fixture system and a method for the same are provided. The system has a circuit board top surface and a plurality of wells. A liquid metal compound forms balls in the wells. An IC package having a bottom surface with electrical contacts interfaces with the liquid metal compound in the wells. In some aspects of the system, the IC package has solid ball grid array (BGA) connectors attached to the bottom surface electrical contacts, interfacing with the liquid metal compound. Alternately, the liquid metal compound interfaces directly to the IC package bottom surface contacts. A gravity-tension frame overlies the circuit board top surface. The frame provides support in the horizontal plane so that the liquid metal balls remain aligned with the IC package electrical contacts. Typically, the liquid metal compound is a mixture of approximately 24% indium and 76% gallium.

Abstract: A system for controlling the flow of fluid through a line 3. The system may include first and second valves (A, B; and 6, 7) in the line 3 between is located a chamber (52, 82), part of which may be filled with fluid having a variable volume (52), and another part is filled with a measurement gas (V.sub.1), such as air. The chamber may be isolated from the pressure effects in the rest of the line by closing both valves. The valves may also permit fluid to flow into or out of the chamber. The second portion of the chamber has a common boundary with the first part in such a way that the combined volume of the first and second parts is constant. A loudspeaker (22, 33, 571) creates sound waves in the gas in the second part of the chamber, in order to measure the volume of the fluid in the first part, and for directing the operation of the valves and creating subsonic pressure variations to produce the desired flow. The volume measurement is achieved by acoustic volume measurement techniques.

Abstract: The present invention provides an improvement for a document feeder comprising a feed deck, a separator assembly for separating and feeding individual documents, the separator assembly including a separator wheel disposed above the feed deck, drive structure for driving the separator wheel, and structure for adjustably positioning the separator wheel assembly to a position relative to the feed deck commensurate with the material being fed. The improvement comprises structure for pivotally coupling the document feeder to vertical frame members. The coupling structure is located at one end of the document feeder near the separator assembly. There are a pair of leg members extending below the feed deck, each of the leg members resting on a horizontal frame member at opposite sides of the document feed path. The leg members are laterally spaced so as not to interfere with documents being conveyed by the underlying document transport.

Abstract: A system for controlling the flow of fluid through a line (3). The system may include first and second valves (A, B; and 6, 7) in the line (3). Between the first and second valves is located a chamber (52, 82), part of which may be filled with fluid having a variable volume (52), and another part of which is filled with a measurement gas (82, V.sub.1), such as air. The chamber may be isolated from the pressure effects in the rest of the line by closing both valves. The valves may also permit fluid to flow into or out of the chamber. The second portion of the chamber has a common boundary with the first part in such a way that the combined volume of the first and second parts is constant. A loudspeaker (22, 33, 571) creates sound waves in the gas in the second part of the chamber, in order to measure the volume of the fluid in the first part.
