Abstract: A process for the manufacture of high purity, ultra-fine aluminium nitride powder by the carbo-nitridisation of alumina. Agglomerates uniform in both size, chemical composition and porosity are formed containing a stoichiometric mixture of alumina and carbon with the addition of a small amount of catalyst. The agglomerates are furnaced in a controlled manner in a well-mixed reaction vessel to achieve a uniform and consistent level of conversion. Milling of the as-reacted agglomerates under a controlled at mosphere will produce high purity, micron sized aluminium nitride powder.

Abstract: Blood constituents are separated by centrifugation in a transparent tube which contains a float for physically elongating certain of the constituents. The centrifuged sample in the tube is positioned on a layer measuring device with which red cell and buffy coat constituent band heights can be measured in ambient light. The buffy coat constituent measurements are made under optical magnification. The measuring device has a mathmatically derived red cell layer nomogram printed thereon, and a separate scale for measuring buffy coat constituent bands. Conversion tables are provided for converting the measured buffy coat constituent band lengths into constituent cell counts. The measuring device includes tube-engaging portions for properly positioning the tube during the measurements, and the red cell scale automatically compensates for the presence of the float and densification of red cells needed for proper banding.

Abstract: These alloys are made up of crystals of the said metals in solid solution which have a particular size and specific surface. They are obtained by coelectrodeposition of the metals in a molten salt bath. In the case where the metals exhibit a difference smaller than 0.5 volt in their deposition potential, the metals are delivered into the bath in the form of chlorides. In the case where this difference is greater than 0.5 volt, the least electronegative metal is delivered in the form of a chloride whereas the most electronegative metal is delivered by means of a soluble electrode. The invention finds its application especially in the production of Nb-Ti and Hf-Zr ingots.

Inventor: PENN STEVEN M
IPC: G05B19/418

Abstract: A method and process for computer-controlled manufacture of three-dimensional objects involves dispensing a layer of a first material, such as a liquid, insoluble material onto a platform at predetermined locations corresponding to a cross-section of the object, which then hardens. A second medium, preferably water soluble, is then sprayed onto this layer to thereby encapsulate the hardened insoluble media. The uppermost surface of this encapsulant is planarized, if necessary, for example by way of a mill cutter, knife, roller or thermal bar, thus removing a portion of the encapsulant to expose the underlying insoluble material for new pattern deposition. The dispensing of the first and second materials, and the planarization, may be performed in a single pass by an integrated printhead. After the resulting planing residue is removed, another layer of liquid, insoluble medium is dispensed onto the planed surface. These steps are repeated, until the desired three-dimensional object, surrounded by a mold, is completed. At this point, the object is either heated or immersed in a solvent, thereby dissolving the mold and leaving the three-dimensional object intact; alternatively, the second material may remain in place to form a composite structure such as a printed circuit board. A method is also disclosed which converts a CAD data base representing a solid object into one representing a filled shell, reducing the amount of object material required. <IMAGE>
