Abstract: Disclosed are bacteria and methods for promoting growth of Racomitrium canescens, tobacco, barley and soybean. The bacteria are selected from the methanol-utilizing bacteria deposited under Accession numbers FERM BP-11078, FERM BP-11079, FERM BP-11080 and FERM BP-11071, respectively which bacteria belong to the genus Methylobacterium. The methods are a method for promoting growth of protonemata of Racomitrium canescens which method is characterized by culturing the protonemata in the presence of the bacteria and a method for promoting growth of a seed plant selected from the group consisting of tobacco, barley and soybean which method is characterized by culturing seeds of the seed plant while contacting the seeds with the bacterium deposited under Accession number FERM BP-11078 which is one of the above-mentioned bacteria.

Abstract: Disclosed are novel N-oxyl compounds of the following formula (1). wherein n is an integer of 1 to 18; R1 and R2 are each hydrogen or methyl, but at least one of them is hydrogen; R3, R4, R5 and R6 are each a straight-chain or branched alkyl group; and R7 is hydrogen or (meth)acryloyl. When these compounds are added to vinyl monomers such as &agr;,&bgr;-unsaturated carboxylic acids and esters thereof, they exhibit a satisfactory polymerization-inhibiting effect even at low contents and even at elevated temperatures.

Abstract: A dental adhesive coating base composition comprising a copolymer represented by formula (I) or (II) in an amount of from 5 to 40 wt % based on the total amounts of the composition; and an oral composition comprising at least one of a copolymer represented by formula (I) and a copolymer represented by formula (II) in an amount of from 5 to 40 wt % based on the total amount of the composition, at least one of a phosphoric acid and tartaric acid present in an amount effective to increase the solubility of fluoride in the composition, up to an amount of 6 wt % or less based on the total amount of the composition; a fluorine-containing compound in an amount effective for dental caries prevention; and a volatile nonaqueous solvent are disclosed: ##STR1## wherein R.sup.11 represents an alkyl group having from 1 to 10 carbon atoms; R.sup.12 represents a lower alkyl group having from 1 to 2 carbon atoms, provided that three R.sup.12 groups must be the same; R.sup.13, R.sup.14, R.sup.15, R.sup.16 and R.sup.

Abstract: A distillation process is used to separate methanol from a mixture of methanol with methyl acrylate or methyl methacrylate, as well as from a mixture of methanol and water with methyl acrylate or methyl methacrylate with the use of an azeotropic solvent, which forms an azeotropic mixture with methanol. In distilling such a mixture by the use of a distillation column:(1) part of the condensate of vapors distilled over from the top of the distillation column top is returned to the top of the column;(2) the remaining condensate is separated into two layers;(3) the upper layer essentially composed of an azeotropic solvent from the two separated layers is fed to an intermediate portion of the distillation column;(4) the lower layer essentially composed of methanol from the above two separated layers is withdrawn from the distillation system; and(5) methyl acrylate or methyl methacrylate, or else, methyl acrylate or methyl methacrylate and water, are recovered from the bottom of the column.

Abstract: The invention provides a shaped resin article for optical use which is a three-dimensional reaction product cast from a molding composition essentially comprising a tetrahalobisphenol A epichlorohydrin polycondensate-(meth)acrylic acid adduct (A) and a polyisocyanate compound (B). In another aspect of the invention, the resin article is cast from a composition containing a styrenic or ester monomer (C) in addition to (A) and (B). In still another aspect, the resin article is cast from a composition containing a phenolic compound (D) in addition to (A), (B) and (C).

Abstract: A method for brazing aluminum components with a flux, wherein the flux and the aluminum components are heated together in a brazing furnace filled with a nonoxidizing gaseous medium, thereby fluxing and brazing the aluminum components at one time, or wherein the flux is previously pulverized and electrostatically deposited on the aluminum components, and the fluxed aluminum components is heated to a brazeable temperature in the furnace, thereby melting the braze metal and effecting the braze joints between the aluminum components.

Abstract: This invention relates to a method for the purification of glycidyl acrylate or glycidyl methacrylate. Specifically, the invention effects the purification by using a residual catalyst-inactivating additive and consequently produces highly purified glycidyl acrylate or glycidyl methacrylate containing substantially no epichlorohydrin and having a low chlorine content.
