Abstract: A solid cathode in a fused salt electrolytic cell for the production of aluminum is made up of individually exchangeable elements (10). These cathode elements are made up of two parts which are rigidly joined together and which are resistant to thermal shock. The upper part (12) which projects from the molten electrolyte (30) into the precipitated aluminum (26), or the coating on this part (12), is made of a material which, at working temperature, is a good electrical conductor, is chemically resistant and is wet by aluminum. The lower part (14,16), which is exclusively in the liquid aluminum (26), or the coating on this part (14,16) is on the other hand made of an insulating material which can withstand molten aluminum.

Abstract: A silicon aluminium oxynitride product having the crystal lattice structure of silicon oxynitride but of expanded cell dimensions is produced by sintering a powder mixture of 50 to 60 wt % of Si3N4, 22 to 35 wt % SiO2, 1 to 20 wt % Al2O3 and 1 to 15 wt % of at least one oxide of Y, Li, Mg, Ca, Sc, Ce or another rare earth element, the molar ratio of SiO2 to Si3N4 being greater than 1:1 and the percentages being based on the total weight of the ingredients. Sintering is effected at 1600 DEG  to 1900 DEG  C. in a non-oxidizing atmosphere so that the Al2O3, said at least one oxide and part of the SiO2 in the mixture react to form a liquid phase from which silicon aluminium oxynitride having an expanded silicon oxynitride crystal lattice is crystallized. The sintered material is cooled to form a product containing said silicon aluminium oxynitride and at least one grain boundary phase containing silicon and the metal(s) of said at least one oxide.

Abstract: The invention relates to a method and a plant for cooling gases and removing dust from them. In a first step after saturation with water vapour, the gas is brought to accelerate, additional water being simultaneously added to the dust particles in the gas, whereupon the gas flow thus loaded is brought to pass over the surface of the water in a first sedimentation container (1) so that the majority of the dust content is released to the sump in the sedimentation container (1). The gas flow is thereafter subjected to final cleaning and cooling in a second step, through direct contact with water, whereupon the water utilized in this manner, possibly via a second sedimentation container (2), is wholly or partially returned to the first step.

Abstract: Method and installation for the treatment of liquids, especially oxygen enrichment of water is used for aqua culture purposes such as the breeding of fish. Thus, it is an object to provide a method where gas bubbles in the water reservoir are avoided and where one freely can treat fresh water and/or recirculated water for optimal temperature control and/or water renewal. The water flow is mixed with a flow of pure oxygen gas which is supplied from an oxygen tank 4 with liquid oxygen. The oxygen is led through an evaporator 16 into a flow system which forms a recirculating circuit, with pipeline, and oxygen enrichment means or reactor unit 2 where water and oxygen are mixed to form a turbulent, foaming gas/liquid flow. The mixture is subsequently led into a gas/liquid separator 3 where gas and liqid are separated. The gas mixture from the separator which now in addition to oxygen also will contain other contaminants like nitrogen and carbon dioxide, is recirculated by means of a compressor 6. To prevent the building up of great amounts of nitrogen and other contaminants, there is provided a de-aeration means in the form of a bleed 10 or in the form of a special separation unit.

Granted: 1994-02-01
Abstract: ABSTRACT   The present invention is an improvement to a two distillation column cryogenic air separation process which produces nitrogen-rich and oxygen-rich products.  The improvement to the process is condensing at least a portion of the nitrogen overhead from the high pressure column in a reboiler/condenser against a crude liquid oxygen stream and in an intermediate reboiler/condenser located in the low pressure column against internal low pressure column streams.  The condensed nitrogen overhead is fed either to the low pressure or high pressure columns as reflux.  The vaporized portion of the crude liquid oxygen stream is work expanded to provide some or all of the refrigeration required for the process.

Title: Diagnostic assay module
Inventor: BOWEN MARK STANDER
IPC: B01L3/00
Filed: 1990-06-26
Granted: 1995-09-19
Abstract: A diagnostic assay module for analytical procedures in which an optical signal developed by interaction between a component in a sample fluid, such as an analyte in a biological fluid, and one or more reagents in a resilient assay element is read by optical means.  The module includes a first member having one open side and a second member adapted to close the open side of the first member against a resilient assay element.  The area of the assay element to which the sample fluid is applied and wherein the optical signal developed by the interaction of the sample component and the reagent(s) in the assay element is read is maintained in a substantially horizontal orientation by flexure developed between complementing ramp surfaces on the respective first and second members. In a preferred embodiment the first member defines a liquid transport surface which, together with the assay element forms a fluid flow zone to provide for the uniform spreading of a sample fluid, introduced through an aperture in the member, across the surface of the assay element.  The volume of fluid in the fluid flow zone is controlled by the precise positioning of the assay element according to the invention.

Abstract: A fluid apparatus including a fluid tank having a shell and defining a fluid containment compartment. A well is recessed into the fluid tank at an opening in the shell. The well has a well wall secured to the shell and a support ring at the shell opening and secured to and inside of the well wall. A cover plate is removably securable to the support ring to form a pressure-tight connection rel-ative to the interior of the well such that the cover plate can retain in the well a pressure at least as great as the working pressure of the fluid in the compartment. This pressure-tight securement is prefera-bly made by threading bolts through the plate and into drilled, tapped blind holes in the ring. The well can have a well head secured to the well wall and opposite to the shell opening. The well head in turn can be equipped with an internal manway cover openable into the tank and closable in a pressure-tight manner relative to the well wall.
