Abstract:
A method of manufacturing a shoe upper is provided. The method comprises coating at least a portion of a footwear upper, made of leather or synthetic materials or fabric, with an ultra-violet curable composition having sufficient polymerizable functionality to cure to a thermoset state, but having insufficient polymerizable functionality to embrittle the resin when cured. The coating is exposed to ultra-violet radiation sufficient to cure the coating.
Abstract:
An autodepositing aqueous coating composition has a pH of 1.6 to 5.0 and comprises resin solids, acid, oxidising agent, water, anionic surfactant either as a free component or as a copolymerized component in the said resin, and other optional components, with the resin solids being dispersed in the water and being polymer resin solids principally composed of specified proportions of the following monomers: (A) methyl methacrylate and/or acrylonitrile, (B) ethyl acrylate and/or butyl acrylate, and (C) acrylic acid and/or methacrylic acid and with the anionic surfactant being present in a specified proportion based on the total amount of the said components (A), (B), and (C). Such an autodepositing composition produces on active metal surfaces contacted with it a high corrosion-resistant coating, even without any post-treatment with an aqueous hexavalent chromium solution.
Abstract:
The present invention relates to compositions and methods for improving the performance of lead-acid storage batteries, and reducing corrosion in lead-acid storage batteries, including the plates, terminals, posts, and cables. Compositions of the invention include cathodic inhibitors and solutions of cathodic inhibitors.
Abstract:
The phenomenon of "mapping" (surface defects) after electrophoretic painting over phosphate conversion coatings passivated with hexavalent chromium containing passivating compositions can be avoided or reduced by keeping the surface being treated constantly wet from the time it is conversion coated until it is electrophoretically painted, by preceding the passivating step by treatment with an aqueous liquid treatment composition comprising at least one of the following components: (A) a water soluble and/or water dispersible polymer with a weight average molecular weight of at least 500; (B) fluorometallic acids and anions thereof, the molecules of which consist of (i) at least one atom of boron, silicon, zirconium, iron, aluminum, or titanium, (ii) at least four fluorine atoms, and, optionally, (iii) one or more atoms of oxygen, hydrogen, or both; (C) zirconium salts of ethylenediamine tetraacetic acid; and (D) alkali metal and ammonium zirconyl carboxylates and carbonates; or by replacing the chromium containing passivating composition with an aqueous liquid treatment composition of the same type as described above.
Abstract:
Apparatus for transferring liquid from a first tank (2) to a second tank having a supply line (4) coupled to the first tank, a fill line (6), a return line (10) leading to the first tank (2) or a sump, a pump (P1) switchable between a fill mode and a purge mode, and a programmable control for placing the apparatus in a purge mode in response to any one of the following signals, a signal indicating the fill line (6) is not properly attached to the second tank, a signal indicating that the liquid in the second tank has reached a given level, and a signal that the volume of liquid delivered by the pump (P1) is that which will fill the second tank to the given level. The programmable control detects leaks and checks whether the rate at which the pump (P1) delivers liquid is within a given range.
Abstract:
A method for the recovery of extractant from the aqueous effluent continuously exiting from a solvent extraction circuit, in which the effluent is contacted with the same water-immiscible diluent being used in the circuit as solvent for the extractant, such that the extractant transfers from the aqueous effluent phase to the diluent phase. A mixer-settler unit (1) having a mixer compartment (2) and an agitator (3) can be used. The diluent phase, now enriched in extractant, is separated, in settler compartment (4) for instance, from the aqueous effluent, now depleted in extractant. The separated diluent phase can then be recontacted with effluent or may be combined with the organic phase of the solvent extraction circuit.
Abstract:
A composition and process for enhancing the aesthetic and tactile properties of an alkyl polyglycoside involving combining an alkyl polyglycoside having the general formula (I) RO(Z)a wherein R is a monovalent organic radical having from about 8 to about 18 carbon atoms; Z is a saccharide residue having 5 or 6 carbon atoms; and a is a number having a value from about 1 to about 6, with an aliphatic alcohol having from 1 to about 20 carbon atoms.
Abstract:
A finish composition and process for enhancing the cohesion of fibers and textile materials wherein the composition contains from 7 to 20 weight percent of an antistatic agent, from 0 to 80 weight percent of an emulsifier, from 15 to 50 weight percent of a polyethylene glycol, and the balance, a lubricant.
Abstract:
Personal cleansing bars having a relatively high moisture content are made by forming a soap composition comprised of a neutralized tallow-free fatty acid mixture having an iodine value of less than about 7 and an alkyl polyglycoside of the formula (I): R1O(Z)a, wherein R1 is a monovalent organic radical having from about 6 to about 30 carbon atoms; Z is saccharide residue having 5 or 6 carbon atoms; a is a number having a value from 1 to about 6. The soap composition is then finished to produce a bar having from about 15 % to about 30 % by weight of water.
