Abstract: A system and method is provided for implanting tooth analogues in the jawbone resulting in aesthetically and functionally desirable gingival tissue contours after restoration. The system permits modification and adaptation of the tooth analogue to meet intraoral demands in a manner similar to that used in the preparation and restoration of natural teeth. The system comprises a standard fixture (12) and cover screw passed through opened gingival tissue and implanted in the jawbone. After the ossointegration of the fixture, the gingiva is reopened, the cover screw removed and a healing cap (30) having a predetermined contour, is attached to the fixture. The reopened gingiva re-heals in a shape determined by the contour of the healing cap. The healing cap is then removed and replaced by an abutment (4,6,9) having an emergence profile matching that of the healing cap. An immediate snug fit between the gingival tissues and the abutment is thereby provided at the time of connection of the abutment to the fixture. A crown (2) is removably attached to the abutment by a screw (90) extending through the side of the crown into the abutment. An improved version of the healing cap is a healing cap created in two portions (138,140) so that one portion (138) around which gingiva tissue regrows remains in the patient and only a second upper portion is removed (140), and an improved abutment (204) which is engagable with the portion of the healing cap left in the patient is used for the abutment about which the crown is removably attached.

Abstract: The closed-channeled, multi-passaged nozzles have gas-permeable refractory walls, allowing the escape of gases that may be dissolved in the molten metal and become expelled or liberated from it while the molten metal is flowing through the passageways in the nozzle. Gaseous voids in the continuously cast product are thereby avoided, notably in aluminum casting as shown by experimental results to date. The nozzles are made from gas-permeable refractory material having interconnected porosity -- that is, interconnected void interstices -- extending through the nozzle walls. The interconnected void interstices are of sufficient size for allowing the passage of hydrogen gas through the walls, while being sufficiently small for preventing the leakage of molten metal. The gas-permeable refractory material is relatively non-wettable by the molten metal. For example, the nozzles are made of fibrous sintered refractory material -- for instance, fibers of alumina or silica intertwined and cohered within a major volume-percentage of interstitial voids, which provide the interconnected porosity. Such fibrous material displays high resistance to thermal shock. It is relatively compliant to nozzle clamps, with consequent resistance to breakage, while the coefficients of thermal conductivity and thermal expansion of such fibrous refractory material are advantageously low.

Abstract: A method is described for the recovery of high yields of monomers from waste and scrape polymeric materials with minimal amounts of char and tar. The process involves heating the polymer at a heating rate of at least 500 DEG  C./sec in a flow-through reactor. Heating is accomplished by contacting the polymer with a heat transfer material such as hot incandescent sand. A flow-through reactor is used to provide the high heating rates and short reactor residence times for the monomer product. The flow through reactor may be a circulating fluidized bed reactor, an entrainment reactor, a cyclonic reactor or a gravity reactor.

Abstract: A ligand-mediated immunofunctional assay (LIFA) method for detecting the presence and the concentration of polypeptide hormone binding proteins which comprises capturing the binding protein with a solid phase bound first antibody, saturating the bound hormone binding protein with the ligand polypeptide hormone, and detecting the bound ligand polypeptide hormone with a detectably labeled second antibody specific for the ligand polypeptide hormone. In the absence of added saturating polypeptide hormone, the LIFA measures the amount of hormone binding protein bound to the endogenous ligand polypeptide hormone. A growth hormone binding protein assay illustrates the method of the present invention. LIFA assay results indicate that increased binding protein substantially increases growth hormone activity. Methods of use and formulations of growth hormone binding protein, growth hormone, insulin-like growth factor-I and insulin-like growth factor binding protein are disclosed.

Abstract: An object of the invention is to overcome disadvantages of prior practices. A further object of the invention is to provide a process for providing particles that result in improved UV absorption in photographic products. An additional object is to provide lower cost polymer particle dispersions. The invention is generally accomplished by mechanically grinding a crystalline material to a desired particle size in a liquid that is not a solvent for the material, heating said crystalline particles dispersed in said liquid to above their melting temperature, and cooling the melted particles in said liquid to form amorphous particles. In preferred forms of the invention, the material is a photographically useful material, such as ultraviolet light absorber or coupler.

Transfermix machinery has a first component (1) with an internal helical thread (5) and a second component (2) with an external helical thread (4), of opposite hand but co-axial with the first thread, and co-operating so that the threads face each other and define a passage for a medium to be processed. The cross-sectional areas of the grooves of the threads vary along their length in opposite senses between maximum and minimum values. The thread (4) of which the cross-section is being reduced has at least two starts (9, 10, 11, 12) of which a first, (9), over a part of the length, is reduced at a lesser rate than the second, 10, and over a different part of the length the first start (9) is reduced at a greater rate than the second (10).
