Title: Manufacturing process of spray urethane elastomer
Inventor: TANIGUCHI KAZUO
IPC: C08G18/10
Filed: 1989-12-27
Abstract: bstract of the Disclosure This invention relates to a process for manufacturing a spray urethane elastomer, more particularly to a process for manufacturing a solventless, non-cellular spray urethane elastomer, which comprises spraying a partial prepolymer component having a high molar ratio of NCO/OH prepared from an organic polyisocyanate and from polytetramethylene ether glycol (PTMEG) having a molecular weight of 400 to 2000 and a resin component containing the PTMEG, a specified chain extender and an organobismuth compound catalyst onto a substrate by use of a two components high pressure spray machine.    According to the present invention, spraying only of the stock solutions by use of the two components high pressure spray machine accomplishes coating and the stock solutions are cured in one second to ten and several seconds after being sprayed without producing cells even when thick-coated.  Therefore, the present invention makes it possible to effect wet-on-wet coating within a short period of time, resulting in making it possible to accomplish a coating having a predetermined thickness in a short period of time.      An elastomer, which has been coated, is excellent at modulus, tensile strength, elongation, tear strength, heat resistance, and the like, such as pipe, tank and the like, waterproof materials such as concrete for the roof and outside wall which need waterproofness, thick-coated protective coating for a thermal insulant such as rigid polyurethane foam, polystyrene foam, board or the like, seamless floor covering material, open mold molding by use of a mold made of metal or resin, and the like.

Title: Microencapsulated taste-masked water-insoluble nsaid drug materials
Inventor: POWELL THOMAS C
IPC: A61K9/62
Filed: 1990-01-17
Abstract: ABSTRACT OF THE DISCLOSURE      This disclosure is directed to preparation of individual taste-masked, high payload, microcapsules by microencapsulatio of water-insoluble NSAID drug materials in the substantial absence of microcapsule agglomerates.  These taste-masked micro-capsules contain a high payload, e.g., about 83-~ wt.~ of said NSAID drug material and can then be formulated into chewable tablets and liquid aqueous suspensions for medicinal use.          Cellulose acetate phthalate is the micro-encapsulating polymer wall material.      Control of pH, controlled addition of a Hofmeister (lyo-tropic) salt, microencapsulation of the water-insoluble NSAID medicament with a liquid phase of cellulose acetate phthalate microencapsulating material and the subsequent insolubilization of said liquid encapsulating material after it is wrapped around the medicament core with dilute acid are important process parameters to achieving the proper individual microcapsules to obtain taste-masked, water-insoluble NSAID drug materials, esp., naproxen and ibuprofen, by microencapsulation alone.

Title: Biological production of novel cyclohexadienediols
Inventor: MADER ROGER A
IPC: C12N9/02
Filed: 1990-02-23
Abstract: Abstract of the Disclosure Meta-hydroxyphenylacetylenes are produced from phenyl-substituted ketal or acetal precursors. Using biotransformation processes, these precursors serve as substrates that are converted to cis-dihydrodiol intermediates.  The cis- dihydrodiols can be converted chemically to the corresponding meta-substituted compounds, e.g., meta-substituted phenols, and then to m-hydroxyphenylacetylene, which is an intermediate needed to produce acetylene-terminated resins.  The biotransformation step employs arene-2,3-dioxygenase in intra- or extra- cellular form.

Title: Arrangement for measuring a deviation from its line of a movable web of foil
Inventor: WESSNER MICHAEL
IPC: B65H23/02
Filed: 1990-02-28
Abstract: The arrangement comprises a tracking sensor with a light source, an optical means and a receiver with two photosensitive detectors, as well as a measuring apparatus with a computing unit. The optical means focuses light to provide a beam which falls on a moving web of foil.      The tracking sensor may, for example, be installed in a re-winding installation, and during re-winding of the web, senses by means of the beam a marking track which is embossed in the web in the longitudinal direction of the web and which is composed of two different diffraction grating tracks. Each diffraction grating track projects the light diffracted therefrom in a predetermined direction of incidence to a respective detector. The sensed signals supplied by the receiver are converted into a difference signal by the measuring apparatus, and processed to provide correction signals which are supplied to a control means of the re-winding installation in order to compensate for lateral deviation of the moving web of foil.

Filed: 1991-01-29
Abstract: A first metal, for example a transition metal such as cobalt, having an insoluble hydroxide is separated from a second metal such as lithium having a soluble hydroxide in an aqueous liquid containing dissolved rations of the metals. The cations are firstly absorbed onto a cation exchange material by electrochemical ion exchange and the second metal then selectively eluted by electrochemical ion exchange under sufficiently high pH conditions, e.g. to 10-13, in a closed loop. Finally, the transition metal is eluted by electrochemical ion exchange under sufficiently low pH conditions, e.g. acidic such as 1-2. The method is applicable to separating trace quantities of Co (e.g, as Co-60) from larger quantities of Li in aqueous solution.
