Abstract: The forming of an adherent platinum coating on the surface of hard, highly dense refractories by plasma flame spraying thereon an intermediate layer of a refractory oxide selected from the group comprised of zirconia, zircon, alumina, cordierite, mullite, or zirconia-alumina-silica having a particle size between 140 and 200 mesh, and further plasma sraying thereon a substantially 20-100 micron size platinum powder which is densified by heating to temperatures of 1350.degree.-1600.degree. C.

Abstract: In a combined bake and seal process for manufacturing a cathode ray tube, wherein screen baking and panel-funnel seaing are accomplished in a single sealing step, chemical reduction of the panel-funnel seaing glass by organic screen components is suppressed by providing an oxygen-evolving agent within the tube during sealing.

Abstract: Immobilized microbe composite comprising a porous, high surface area inorganic support having a controlled population of microbes bonded to the internal surfaces of the pores, the support being water insoluble, non-toxic to the microbes, and having a controlled porosity such that at least 70% of the pores, on a pore size distribution basis, have a pore diameter at least as large as the smallest major dimension of the microbes but less than about five times the largest major dimension of the microbes. The composites are especially useful in situations requiring a high biomass surface within a relatively small volume.

Abstract: A magnetic recording and storage device having high wear resistance is produced by providing a magnetic recording and storage device having a film of solid magnetic material which has been bonded to a surface of a rigid substrate. A thin film of a lubricating compound is then applied to the film of magnetic material.

Abstract: This invention relates to means for transporting clinical specimens wherein the activity thereof can be retained for relatively long periods of time. The crux of the invention resides in a liquid reagent capable of preserving or stabilizing the activity of a particular specimen. Where the clinical specimen is Neisseria gonorrhoeae, the preferred liquid reagent consists of an aqueous mixture of cysteine and TRIS (Trihydroxymethylaminomethane) buffer. A convenient type of specimen collector comprises a swab. Again, where the clinical specimen is Neisseria gonorrhoeae, the preferred swab consists of calcium alginate. An apparatus particularly useful for transporting specimens comprises a screw-capped container having a liquid reagent sealed into the bottom portion thereof capable of preserving the activity of a particular specimen, and a specimen collector attachable to the inside of said screw cap through a longitudinal element of sufficient length to immerse said collector into said liquid.

Abstract: A modular heat exchange element, adapted to be positioned in fixed relation to one or more other of such modules, may be produced as a monolithic, honeycombed body having a plurality of flow paths therethrough for at least two fluids. The body is provided with a plurality of cells extending from one face end of the body to the other face end thereof and arranged in columns of cells separated by fluid barrier wall surfaces. At least selected columns of cells are closed on both face ends of the body, with inlets and outlets for the selected cells provided by removing portions of the boundary surfaces and fluid barrier walls of the columns of cells near face ends of the body. A first fluid may enter selected columns of cells through the inlets and exit from the outlets near the other end thereof. A second fluid passes through the other selected columns of cells.

Abstract: A method of continuously encapsulating a component is disclosed. A predetermined quantity of viscous encapsulating material is applied to each of substantially opposite exterior portions of the component. Thereafter, an external force is applied to the encapsulating material causing it to flow substantially covering the entire exterior surface of the component, after which the encapsulating material is cured.

Abstract: Chemically-strengthenable silver halide-containing lithium boroaluminosilicate glass compositions having physical and chemical characteristics required for sheet drawing processes and exhibiting excellent photochromic properties after heat treatment, and also strengthened photochromic drawn sheet glass articles provided therefrom, are described.

Abstract: A reflector useful in dental surgical lighting systems has been developed, which reflector is derived from at least one base elipsoid surface which has been divided into sections, each section being rotated outward so as to provide the cumulative effect of several elipsoidal segments to produce a beam pattern of desired width.

Abstract: A coupling for flanged columnar or conduit members is described which produces a desired deformation within the coupled members and provides a preinduced stress of sufficient magnitude and opposite direction to substantially equal opposing deformation and stress encountered during operating conditions of the coupled columnar system.

Abstract: The present invention is founded upon the fundamental discovery that anhydrous silicate materials can be formed into solid bodies which are hydrated or wherein the silicate structure is depolymerized by protonic reagents other than water. Such bodies can be produced by compression molding the anhydrous silicate material with water or other protonic reagent at elevated temperatures and high pressures.

Abstract: This invention relates to the coprocessing of hydrated glass with organic polymers to form integral bodies which can be stronger, tougher, and more durable than the original hydrated glass and stiffer than the original plastic material. The process is amenable to any hydrated glass so long as the processing temperature of the hydrated glass is below the temperature at which decomposition of the organic polymer takes place. Chemical bonding between the hydrated glass and a thermosetting organic polymer is achieved through the use of silane coupling agents. Such are not necessary with thermoplastic polymers. The invention is applicable with both thermosetting and thermoplastic polymers which are resistant to alkali environments.

Abstract: A system for delivering separator material to a drum upon which optical waveguides are wound. The sheet material is delivered to the vicinity of the drum through a partially-enclosed guide and cut to length. Air jets are provided for urging the severed sheet material against the drum so that a succeeding layer of waveguides can be wound upon it.

Abstract: This invention relates to means for determining the presence of Neisseria bacteria in a fluid sample, the method generally comprising reacting antibodies with an enzyme released during lysis of the fluid sample, and then testing for inhibition of activity of the enzyme. Inhibition of enzyme activity caused through the contact of antibodies specific to the enzyme can be readily detected. The enzyme released from Neisseria bacteria upon lysis possesses the faculty of oxidizing 1,2-propanediol and reducing nicotinamide-adenine-dinucleotide (NAD). Although the structure and behavior of the enzyme are not comprehended entirely, the above-mentioned faculty of the material has suggested the term 1,2-propanediol dehydrogenase therefor.The specific inventive feature of the instant method is the use of (NH.sub.4).sub.2 SO.sub.4 to precipitate the antigen-antibody complex which thereby concentrates the enzymes and can remove possibly interfering materials.

Abstract: Certain portions of the discharge slots of an existing extrusion die for forming honeycomb structures are blocked off by selectively positioning a plurality of tabs within such discharge slots so as to convert the cellular configuration originally formed by the discharge slots of such die to that of a desired cellular configuration.

Abstract: Glass or glass-ceramic vessels are formed with a pouring lip wherein wall portions of the vessel below the lip are of a thinner construction than the remaining wall portions so as to impede glass flow to the lip area and facilitate uniform glass flow to upper portions of the vessel during the forming process.
