Abstract: A container (1) for applying a spreadable product (4) such as an adhesive, having an inner tube (3) that is removably mounted in an outer tube (5). A piston-like plunger (12) is disposed in the inner tube (3) and is moveable axially within the inner tube (3), for moving the spreadable material therein to a position projecting from the tubes, for application to a surface. A removable closure cap is provided to enclose the spreadable material within the two tubes.

Abstract: The present invention relates to an applicator for flowable materials to facilitate the repair of damaged metal coatings by allowing the user to quickly, safely, and accurately apply a metal coating solution to a specific portion of a metal surface, alleviating the need to re-immerse the entire metal item in a coating bath. This is particularly advantageous where the metal item is a portion of an automobile chassis or an aircraft which cannot be easily removed. Further, the applicator is a hand-held device which features a safety collar which protects the user from potentially harmful treatment solutions and, because the applicator enables the user to deliver metal coatings accurately and efficiently, chemical waste is essentially eliminated.

Abstract: To prevent the deterioration in water-resistant secondary adherence that occurs during prolonged use of a fluoride-containing phosphate conversion coating liquid composition to form a conversion coating on metal surfaces that are at least partly aluminiferous, the aluminum compound-containing sludge produced in the phosphate conversion coating liquid composition as it is used is coagulated and sedimented by adding at least one cationic polymeric coagulant to the sludge-containing phosphate conversion coating liquid composition.

Abstract: The formation on the surface of Mg-containing metal of a highly corrosion-resistant, highly rust-inhibiting, and strongly paint-adherent conversion coating, using a chromic acid free treatment bath, is achieved by treatment with a pH 2.0-5.0 aqueous bath that contains phosphoric acid, manganese ion, and amine, thereby forming a conversion coating that contains P--Mn and Mn--N and/or other nitrogen compounds.

Abstract: An installation for lubricating, cleaning and/or disinfecting conveyor belts for containers, more particularly for foods, such as bottles, glasses, cans, bags and the like, comprising a central metering station connectable to a water pipe used to dilute a concentrated lubricant, cleaner or disinfectant, and several distributing pipes connected to the metering station lead to the points of use. At each point of use there is a mixing valve (13-19) connectable to distribution line (52) and the water pipe (23) and individually adjustable for each point of use and a pressure reducer (50, 51) fitted upstream of each mixing valve. Varying concentration can be provided for each point of use (31-37) with little technical complexity. In another embodiment, the invention is the process carried out by the installation.

Abstract: An aqueous liquid chromate free primary composition for forming a protective coating on metals, particularly aluminum, is made by reacting cobalt(II) cations, carboxylate anions, at least one other type of coordinate complexing agent for cobalt(III) cations, and an oxidizing agent in an aqueous solution in which the molar ratio of carboxylate anions to cobalt(II) cations is from 0.10 to 6.8 and the aqueous solution contains no more than 1% of each of ammonia, ammonium ions, and nitrite ions. The primary layer formed by this or any other composition that forms a coating containing metal atoms and oxygen atoms on a metal substrate is advantageously sealed by further treatment with an aqueous solution of sodium ammonium decavanadate, optionally after an intermediate step of immersing in water for a few minutes between the primary treatment and the sealing treatment.

Abstract: Relates to the direct esterification of phenols, particularly alkyl-substituted phenols, with a carboxylic acid or anhydride, in the presence of a strong acid catalyst. Also relates to the use of the acid anhydride to drive the esterification reaction to completion, where an initial reaction mixture has been formed using the carboxylic acid. Further relates to the achievement of economies in esterification by recovering dilute aqueous acid when either the acid or anhydride is used initially, for recycling to achieve economies of acid use.

Abstract: To improve the water resisting secondary adhesion of paint films to zinc phosphate conversion coatings on aluminum, the initially formed conversion coating is treated by spraying with a second liquid treatment composition that either is itself a liquid composition capable of forming a zinc phosphate conver- sion coating on aluminum or is made by diluting such a conversion coating forming composition.

Abstract: A reaction rinse containing strong alkali, betaine surfactants, and a complexing agent for iron enhances the gloss of a dried and cured autodeposited coating that is contacted with the reaction rinse while still wet, particularly if the autodeposited coating consists predominantly of a copolymer of vinylidene chloride.

Abstract: A method for emptying a substantially, completely compressible container filled with a thixotropic paste, for example, a paste-form detergent. The thixotropic paste is transported by compression by a compressive force of the container toward an opening of the container and through that opening into a connected delivery tube. The compressive force is applied to a limited area of the container to deliver the thixotropic paste which is then transported by a metering pump through the delivery tube to a mixing container where it is mixed with inflowing water.

Abstract: A water-borne autodepositing coating composition that has a pH of 1.6 to 5 and contains as essential components a water-dispersible or water-soluble organic coating-forming resin, a liquid dispersion of carbon black, acid, and oxidizing agent, and that may contain metal ions as an optional component, has an excellent storage stability and produces a strongly adherent and highly corrosion-resistant coating when the liquid dispersion of carbon black is an aqueous dispersion in which carbon black is dispersed using as a dispersant a naphthalenesulfonate-formaldehyde condensate.

Abstract: Printed wiring boards useful for high frequency applications are obtained by laminating a copper foil pretreated with a silane to a polynorbornene prepreg. The prepreg is made by impregnating a fiberglass cloth with a ring-opening polymerized polymer. The copper foil is pretreated with a silane which is capable of improving the bond strength between the copper foil and a norbornene copolymer.
