Abstract: An in-bed staged fluidized bed combustion apparatus includes a reactor vessel having a grate for supporting a bed of sorbent and fuel in the vessel. The sorbent and fuel form a dense phase bed region. Fluidizing fluid for the combustion of the fuel is provided to the vessel through first and second delivery conduits. The first conduit delivers air to the bottom of the vessel. That air flows up through openings in the grate and mixes with the fuel and sorbent to support combustion. The second delivery conduit includes a distribution manifold and an array of spaced tubes that deliver secondary fluidzing air evenly across the reactor vessel at an intermediate point in the dense bed phase region. At least 55% of the combustion air is delivered through the second conduit. Accordingly, the dense bed phase region has a reducing zone formed in a lower portion thereof and an oxidizing zone formed in an upper portion thereof.

Abstract: A horizontal electrophoresis assembly is described which is designed to utilize very thin gels of polyacrylamide. The assembly allows for water cooling of the gel during electrophoresis so that higher voltages can be applied to the gel without polymer degradation. The gel mold is made from a set of glass plates which are clamped into place defining a gel mold between them. In one embodiment, the site of field introduction is separated from the site of sample introduction so that the electric field is generally linear at the region of sample introduction.

Abstract: A superconducting active device has dual control inputs and is constructed such that the output of the device is effectively a linear mix of the two input signals. The device is formed of a film of superconducting material on a substrate and has two main conduction channels, each of which includes a weak link region. A first control line extends adjacent to the weak link region in the first channel and a second control line extends adjacent to the weak link region in the second channel. The current flowing from the first channel flows through an internal control line which is also adjacent to the weak link region of the second channel. The weak link regions comprise small links of superconductor, separated by voids, through which the current flows in each channel. Current passed through the control lines causes magnetic flux vortices which propagate across the weak link regions and control the resistance of these regions.

Abstract: A closed-cover hot cyclone reactor is used to melt and partially reduce particulate iron or ferro-alloy ores fed to it in a stream. Tangential streams of fuel gas or, preferably, producer gas supplied by an associated bath smelter, interact with the spiralling particles as they pass through the reactor. The molten metal travels downwardly along the reactor walls and can be discharged by gravity onto the receiving bath. The system eliminates the need for pelletizing ore and coking coal in smelting of iron products.

Abstract: A foundation support apparatus having at least one concrete piling having a plurality of vertical piling sections surrounded by a sleeve having a plurality of vertical sleeve sections is provided. The vertical piling sections extend from the foundation to below the subsurface water table. The sleeve sections form a continuous sleeve capable of protecting the piling from uplifting soil pressure occurring in the zone of moisture change.

Abstract: Screening of crude extracts of the bark of Annona bullata Rich. (Annonaceae) showed cytotoxic and pesticidal activities. By monitoring with brine shrimp lethality, two novel extremely potent acetogenins, bullatacin (1) and bullatacinone (2), were isolated. Spectral and chemical methods identified bullatacin as a diastereomer of asimicin. Bullatacinone represents bullatacin with the lactone cleaved and reformed at the 4-OH. Unlike asimicin, which is more generally cytotoxic, 1 and 2 show some selective cytotoxicities in human tumor cell lines, and certain susceptible cells give ED.sub.50 values as low as 10.sup.-12 -10.sup.-15 mcg/ml. Bullatacin was pesticidal at concentration as low as 1 ppm, while bullatacinone lacked pesticidal activities.

Abstract: The present invention encompasses a receptor protein present on the surface of natural killer cells (NK cells) and non-specific cytotoxic cells (NCC) which is involved in non-specific lysis of target cells bearing an antigen recognized by the receptor protein and monoclonal antibodies which bind to the receptor which are useful in their identification and purification, and methods for altering NK cell-mediated lysis of target cells.The monoclonal antibodies (mAbs) of the present invention were prepared by cell fusions between spleen cells from mice immunized with either non-specific cytotoxic cells (NCC) from catfish (anti-receptor antibodies) and myeloma cells.The NK cell receptor was purified from solubilized flow cytometry purified non-specific cytotoxic (NCC) using antigen-antibody complexing techniques, either immune precipitation or affinity chromatography on Affigel-10.TM. with Con A Sepharose purified mAbs.

Abstract: A composition that expands against an exerted pressure, which comprises a polymeric material having an inverse temperature transition in the range of liquid water, wherein at least a fraction of the monomers in the polymer contain a hydrophobic group that is present in an amount sufficient to provide PdV/dS for the polymer of at least 0.2.degree. K. The composition can be used in a variety of different application to produce mechanical work or cause chemical changes in a sealed environment by varying the pressure on the composition, with the degree of mechanical or chemical change being controlled by selection of the number, hydrophobicity, and size of the hydrophobic group and the presence or absence of reactive functional groups in the polymer.

Abstract: Superconductors formed by powder metallurgy have a matrix of niobium-titanium alloy with discrete pinning centers distributed therein which are formed of a compatible metal. The artificial pinning centers in the Nb-Ti matrix are reduced in size by processing steps to sizes on the order of the coherence length, typically in the range of 1 to 10 nm. To produce the superconductor, powders of body centered cubic Nb-Ti alloy and the second phase flux pinning material, such as Nb, are mixed in the desired percentages. The mixture is then isostatically pressed, sintered at a selected temperature and selected time to produce a cohesive structure having desired characteristics without undue chemical reaction, the sintered billet is reduced in size by deformation, such as by swaging, the swaged sample receives heat treatment and recrystallization and additional swaging, if necessary, and is then sheathed in a normal conducting sheath, and the sheathed material is drawn into a wire.

Abstract: A method of making metal oxide ceramic material is disclosed by which the porosity of the resulting material can be selectively controlled by manipulating the sol used to make the material. The method can be used to make a variety of metal oxide ceramic bodies, including membranes, but also pellets, plugs or other bodies. It has also been found that viscous sol materials can readily be shaped by extrusion into shapes typical of catalytic or adsorbent bodies used in industry, to facilitate the application of such materials for catalytic and adsorbent applications.
