Abstract: Monolithic bodies of sinterable materials are formed by a sintering process in which little or no shrinkage of the body occurs during sintering. In the method, large particles are placed in particle-to-particle contact with finer size powder particles at the interstices to form a molded shape which is then fired. During firing, the large particles are substantially stable, but the fine powder particles sinter to bond the large particles together. The method is especially useful for producing large and/or intricately shaped bodies. The method is also especially useful for making monolithic bodies using large hollow spherical particles.

Abstract: Catalytic cracking catalysts which contain bayerite and/or eta alumina are used to process hydrocarbon feedstocks that contain nickel.

The compounds of this invention are water soluble phosphonomethyl amine oxides having at least one oxidized tertiary amine group of the formula: ##STR1## and water soluble salts thereof and having a cloud point of at least about 25 ppm.

Abstract: Hermetic package designs for HDMI substrates are discussed. The designs for a hermetically sealed, perimeter-leaded package may have the following features:a) a flat monolithic dielectric base, the base having a flat upper surface and a flat lower surface;b) a zone on the upper surface, in which zone the HDMI device would reside;c) a seal ring surrounding the zone;d) a cover adapted to be hermetically sealed to the seal ring, thereby protecting the HDMI device located in the zone;e) a plurality of conductive vias (inner vias) extending from the upper surface inside said zone downwardly toward the lower surface;f) a plurality of perimeter conductive lead pads located on or in the upper surface about the perimeter of the zone inside the seal ring; wherein(1) the perimeter lead pads are electrically connected to the inner vias, and(2) the inner vias are electrically connected to a surface of the base outside the zone.

Abstract: A high temperature control damper for use in an air flotation dryer with built-in afterburner or any other high temperature environment. Two damper blades are mounted between high temperature bearings and rotate in an insulated housing. The inner ends of the damper engage in a ship-lap joint, and the outer ends of the damper engage against sealing flanges.

Abstract: The processes of the invention involve the formation of an initial reactant mixture by combining sources of SiO.sub.2, B.sub.2 O.sub.3, aluminum, and carbon. The mixture may then optionally be shaped or compacted. The reactant mixture is then heated to start a reaction which is described by the formula:4 C+3 SiO.sub.2 +2 B.sub.2 O.sub.3 +8 Al.fwdarw.4 Al.sub.2 O.sub.3 +B.sub.4 C+3 SiC.Depending on the actual reactant mixture compositions and reaction conditions, other reactions may also occur.

Abstract: An electrophoretic matrix comprised of at least one water-insolubilized, temperature-responsive polymeric compound having an LCST is disclosed. The electrophoretic matrix can change its hydrophilic/hydrophobic property by changing temperature. A method of using the electrophoretic matrix involves charging a sample onto the matrix and carrying out electrophoresis at a temperature above or below the LCST of the polymeric compound.

Abstract: A carbon monoxide oxidation catalyst especially useful as a co-catalyst in fluid catalytic cracking operations is made by impregnating particulate alumina with lanthana and a small amount of platinum. Cerium must be excluded.

Abstract: An improved process for preparing alkyl nitroacetates by the gradual addition of nitric acid to a reaction vessel having therein a solution of alkyl nitroacetate and a carboxylic acid anhydride, optionally in the presence of an acid catalyst, at low temperatures to form an alkyl nitroacetoacetate intermediate which can thereafter be cleaved with a nucleophile to form an alkyl nitroacetate.

Abstract: Apparatus for the opening of a bag 1 is provided with a clamp 2 having one fixed jaw 3 which applies a high pressure to a limited area of the bag by means of a pip 4, and a movable jaw 5 which applies a lower pressure to the bag 1 over a larger area through a spring-loaded block 6 and a rubber pad 7, and is movable by means of a pneumatic cylinder 8. The high pressure applied by the pip 4 is sufficient to prevent any relative movement of the bag panels. The lower pressure exerted by the rubber pad 7 is sufficient to prevent sliding movement of the pad 7 relative to the upper surface of the bag 1 but does not prevent relative movement between the upper and lower panels of the bag 1. When the movable jaw 5 is moved towards the fixed jaw 3 a region of the upper panel of the bag is buckled between the two jaws. Raising of the clamp thus opens the bag, the lower side being held down by adhesive tape 9.

Abstract: An improved cryopreservation of embryos has been developed. After freezing in a cryoprotective solution of ethylene glycol, glycerol or a combination thereof, the embryos can be thawed and transferred directly to the recipient animal without serial rehydration. The transfer can be made directly from the cryoprotective container to the recipient animal.

Abstract: Polymeric, oriented films can be made by the use of a combination of a hot blown process and a blown bubble process. Styrene butadiene copolymer (SBC) forms two outer layers of the preferred embodiment, with a core layer of very low density polyethylene (VLDPE) or blends thereof, and intermediate polymeric adhesive layers such as ethylene vinyl acetate copolymer (EVA) bonding the core layer to the outer layers. A monoaxially or biaxially oriented film is produced with excellent optics.

Abstract: N-methyliminodiacetic acid is separated from mixtures of N-methyliminodiacetic acid and sodium sulfate formed by acidification of solutions of its disodium salt with sulfuric acid. Thus the disodium salt is acidified with sulfuric acid to a ph of about 2 and concentrated by evaporating water so as to crystallize sodium sulfate. The sodium sulfate is separated, and the resulting mother liquor is cooled to precipitate N-methyliminodiacetic acid, which is then separated.

Abstract: A plurality of corona-treated polymeric films, and metal foils or sheets, are alternately arranged and laminated together to form a laminate suitable for e.g. insulating panels. Construction of this absolute or near-absolute barrier can be simultaneous or sequential. The metal foils may be of the same type, or may differ. Aluminum and steel are preferred metal foils. At sufficient thicknesses, the sheet can be stamped or shaped. Both outermost surfaces of the laminate can comprise polymeric film, or both surfaces can comprise metal foils. Alternatively, one outer surface can be a polymeric film and the other outer surface can be a metal foil.

Abstract: Fe(III) complexes having high bulk density and a process for the production of the same without the generation of heavy metal-contaminated effluents are disclosed. Solid complexes of EDTANaFe and EDTAKFe having high bulk densities are formed by reaction with ferric sulfate containing low chromium levels, followed by total drying of the resulting mixture in the same processing equipment without the prior separation of the sulfate salts formed.

Abstract: A battery separator for use in deep cycle traction batteries, such as golf cart batteries. The separator is formed of a microporous, mainly polymeric layer, preferably in the form of a synthetic paper; a glass mat layer adjacent one surface of the microporous layer; and a coating on one or both sides of the mircoporous layer/glass mat combination. The coating is preferably formed of natural rubber which positively affects top-of-charge behavior and reduces the possibility of antimony poisoning, thus providing for longer and improved battery performance and life.

Abstract: An apparatus is provided which both floatingly supports a web, and maintains the web in a substantially straight path as it travels through a dryer. The apparatus comprises a steerable air bar assembly comprising: i) one or more adjustable air bars, each having an elongated surface from which air may be discharged, said surface being in opposing relation to the running web, and each having two ends; ii) air supply means, in fluid communication with the air bars; and iii) adjustment means for altering the orientation of the elongated surfaces of the adjustable air bars with respect to the running web. In a preferred embodiment the orientation of the surfaces is adjusted such that each said surface rotates about an axis which is substantially parallel to the longitudinal centerline of the running web. Said steerable air bar assembly is positioned in a web dryer such that the web is guided through the dryer in a substantially straight path.
