Abstract: The present invention relates to a process for the production of pure ammonium metallates of the metals W, Mo, V, Cr and Re, wherein alkaline metal salt solutions are adjusted to a pH value in the range from 5 to 9 by reaction with CO.sub.2, these metal salt solutions are passed through an anion exchanger in carbonate form, wherein, in addition to the alkali metal carbonate solution, the metallate form of the ion exchanger is formed, the ion exchanger is then washed until free of alkali and is then eluted by means of aqueous ammonia to form ammonium metallate solutions and the anion exchanger in the OH form, wherein the anion exchanger is converted into the carbonate form by means of CO.sub.2 treatment and is recycled.

Abstract: A cooling cap (1) made up with knitted net fabric of polyester yarn comprises an outer open-meshed fabric (3) for covering the front half part of the hemispheric part of the cap to receive the human head, an inner fine linen fabric (4) for lining the outer open-meshed fabric, a water absorbent fiber layer (5) for bearing water or absorbing sweat, and a plurality of eyelets or loopholes (6). The head is cooled owing to the vaporization of the water borne in the water absorbent fiber layer by absorbing the heat.

Abstract: A device for automatic dilution of chemical additives and water utilizing a single pump (20) drawing water and other chemical additives through a dilution manifold (10). The introduction of air into the system is monitored such that the system performance is not impaired. If the air leak is small corrections can be made or the system will accept the small error, but if the air leak is large, the system will shut down and activate an indication or alarm to signify that some malfunction has occurred, such as a chemical supply being unconnected or empty.

Abstract: Group communication technology, such as the Horus process, is used to implement a fault-tolerant high performance, reactive, real-time distributed IN coprocessor. The architecture of the distributed IN coprocessor comprises workstation clusters, external adaptors and an update interface interconnected by high speed communication links. Each workstation of the IN architecture represents a query element, so all the databases used by the IN coprocessor in the course of servicing incoming requests are split between query elements, provided that each of the workstations has access to the information stored in a certain database or databases.

Abstract: A dual-lumen catheter is disclosed that allows access to the vascular system of humans or animals for the high volume fluid flow related to hemodialysis or therapeutic apheresis. One lumen is circular with a wall thickness and material such that the lumen remains open during the fluid exchange. The second lumen is relatively thin walled designed to collapse against the first lumen under the pressure associated with the vascular system. This collapsing provide a minimum cross section of the catheter as it enters the body and the vascular system. However, the second lumen opens under pressure as a high volume fluid flow is introduced into the vascular system through the second lumen. This high volume fluid flow into the body is most often a return of fluid removed from the body via the thicker walled lumen.

Abstract: A method of diagnosis of a living organism by providing at least one functional map of the living organism, the method having the steps of determining at least two physical parameters characterizing the physiological state of the living organism, recording spatial-temporal distributions of the at least two physical parameters, acquiring and processing information about the spatial-temporal distributions of the at least two physical parameters, and utilizing the information about the spatial-temporal distributions of the at least two physical parameters to generate the at least one functional map of the living organism. Further steps include using one of the at least two physical parameters as a reference for selecting another of the physical parameters, substantially simultaneously recording the spatial-temporal distributions of the at least two physical parameters or recording the spatial-temporal distributions of the at least two physical parameters at a preselected time interval apart from one another.

Abstract: A method of improving the performance of a traveling wave field-effect transistor operated at frequencies in the microwave range or above the microwave range comprising the steps of forming a depletion region beneath a gate electrode wherein, in a plane transverse to the direction of signal propagation, a depletion region edge has a first end portion located between the gate electrode and a drain electrode and a second end portion located between the gate electrode and a source electrode; and separating the depletion region edge from the drain electrode. Further improvements in the operation of the TWFET include adjusting the first end portion of the depletion region edge to be closer to the gate electrode relative to the distance between the second end portion of the depletion region edge and the gate electrode, controlling an effective conductivity of a semiconductor of the traveling-wave field effect transistor, and setting the length of the gate electode at about one micron.

The composite magnetic bead is comprised of a matrix formed from vinyl monomers throughout which is distributed primary beads, each primary bead of which is a magnetizable metal oxide encapsulated in a rigid polymeric coating. The matrix structure allows the composite magnetic bead to swell in organic solvents without loss of the intermeshed primary beads. Further, the matrix can be functionalized to allow the covalent bonding of sites useful for organic syntheses.The composite magnetic beads are made utilizing a core-shell polymerization techinque under conditions which preserve the oxidation state of the magnetizable metal oxide in the primary particles. In one embodiment, primary beads, each having a hydrophobic exterior surface, are dispersed in an inert solvent with a vinyl monomer and a crosslinking agent for that monomer to form a dispersed phase.
