  • Substituted aluminosilicate compositions and process for preparing same
    Patent number: 4892720
    Abstract: Molecular sieve compositions are prepared by extracting aluminum and substituting titanium and/or iron for extracted aluminum to give molecular sieve products containing framework titanium and/or iron atoms.

  • Biocompatible protein or ligand immobilization system
    Patent number: 4885207
    Abstract: A support matrix generally useful for the immobilization of biologically active proteins is made by coating with a polymeric alcohol a core support of titania or a carbonaceous pyropolymer deposited on a high surface area refractory inorganic oxide, cross-linking the alcohol, and converting a portion of the hydroxyl moieties to sulfonate esters. Such supports covalently bind enzymes and antibodies via a strong carbon-nitrogen single bond to give, for example, an immobilized antibody system extremely resistant to leaching of the antibody, the cross-linked alcohol, or of metals from the core support.

  • Level sensing unit and a level indicating device thereon
    Patent number: 4876799
    Abstract: A level sensing unit, designed to be incorporated in a carpenter's level, is relatively insensitive to the expansion and contraction of the buoyant fluid, independent of the specific gravity of the fluid, and virtually free of oscillations accompanying a change in liquid orientation. The device can be constructed inexpensively of commonly available materials. The device has a cylindrical float mounted on a centrally positioned axle with a plate extending above the float surfaces and placed normal to the axle. The axle extends between the walls of a sealed housing, and adjacent to the edge of the plate are two electrically conducting strips. At level neither strip contacts the edge of the plate, but when the unit is not at level one or the other strip makes physical and electrical contact.

  • Method of cyclodextrin manufacture using an immobilized cyclodextrin glycosyltransferase
    Patent number: 4865976
    Abstract: A process for the continuous production of cyclodextrins employs as a feedstock an aqueous solution of partially hydrolyzed starch with a dextrose equivalent between about 10 and about 15 as the feedstock for an immobilized cyclodextrin glycosyltransferase. In one variant the feedstock is sent to a membrane which removes cyclodextrins and glucose and the retentate is recycled to an immobilized glycosyltransferase so as to effectively utilize the feedstock. In another variant the effluent is passed through a water immiscibled liquid organic compound which forms a solid insoluble complex with cyclodextrins, the solids are continually removed, and the aqueous phase is recycled to an immobilized cyclodextrin glycosyltransferase as in the prior variant.

  • Crystalline gallophosphate compositions
    Patent number: 4861457
    Abstract: A novel family of crystalline, microporous gallophosphate compositions is synthesized by hydrothermal crystallization at elevated temperatures from gallophosphate gels containing a molecular structure-forming template. The family comprises distinct species, each with a unique crystal structure. Calcination removed volatile extraneous matter from the intracrystalline void space and yields microporous crystalline adsorbents with pores, the dimensions of which vary, among the individual species, from about 3A to 10A in diameter. The compositions represent a new class of adsorbents of the molecular sieve type, and also exhibit properties somewhat analogous to zeolitic molecular sieves which render them useful as catalysts or catalyst based in chemical reactions such as hydrocarbon conversion.

  • Styrene terminated multifunctional oligomeric phenols as new thermosetting resins for composites
    Patent number: 4855375
    Abstract: Thermosetting resins which are essentially vinylbenzyl end-capped ethers of the oligomeric condensation products of certain dihydric phenols and formaldehyde are readily polymerized to give an extensively cross-linked polymer particularly useful in printed circuit boards and similar laminates. Effective cost reduction may be enjoyed by replacing up to 50% of the vinylbenzyl moieties by other groups, such as alkyl and benzyl groups, without destroying the usefulness of the resulting thermosetting resins. The vinylbenzyl ether product from bisphenol-A is especially recommended.

  • Alkylated triamines and higher polyamines as curing agents in polyurethane manufacture by reaction injection molding
    Patent number: 4847347
    Abstract: Alkylated polyamines which may be viewed as low molecular weight polymers of x-amino-y-methylenephenyl are effective curing agents in combination with other polyamines and polyols in reaction injection molding for a diverse class of polyisocyantates. Alkylation may range from 5 up to 100 percent to afford polyamines with a broad spectrum of cure times, as well as to give elastomers with an interesting and useful diversity of properties. Such polyamines may be used as a constituent in a blend of polyamines as the isocyanate-reactive component, in which case the elastomer may be viewed as predominantly a polyurea, or as a constituent in a blend with polyols, in which case the elastomer may be viewed as an elastomer with both urethane and urea segments.

  • Polyfunctional vinyl ether terminated ester oligomers
    Patent number: 4845265
    Abstract: There are described vinyl ether terminated ester oligomers which cure or polymerize particularly rapidly, especially by cationic polymerization which is radiation induced in the presence of an onium salt. The oligomeric units arise from the reaction of a polycarboxylic acid having at least three carboxylic acid groups with a diol, although esters with triols and higher polyhydric diols also are useful, especially where an extensively cross-linked product is desired. The carboxyl-terminated oligomeric esters are esterfied with vinyl ether terminated alcohols which can be thought of as the adducts of alkynes and diols.

  • Vinyl-benzyl ethers of phenol-dicyclopentadiene adducts as new thermosetting resins for composites
    Patent number: 4824920
    Abstract: The resins resulting from converting dicyclopentadiene-phenol adducts to their corresponding vinylbenzyl ethers are an excellent matrix in which to embed fibers to produce a composite. Such resins, especially as a blend of materials with varying molecular weight distribution, are amorphous materials whose glass transition temperature is well under the curing temperature, and whose solubility permits solutions with high solids content so as to afford coatings with high resin content. The extensively crosslinked polymer resulting from therma, photochemical, or free radical initiated polymerization has excellent thermal and electrical properties for use in multilayer circuit boards.
