Abstract: A coating composition comprising an oxidized ?-olefin having 16 to 40 carbon atoms and one or more carboxylic acid or ester groups; a hydrocarbon-soluble ester-containing polymer having at least one branch of 10 to 36 carbon atoms and having a number average molecular weight of 5000 to 300,000; a carboxylic acid of at least 10 carbon atoms; a salt of an alkylarylsulfonic acid; an oil in an amount sufficient to dissolve said metal salt; and optionally, a volatile diluent, provides good rust protection.

Abstract: An olefin or a slack wax of 10 to 100 carbon atoms is oxidized by mixing said wax with a salt of an alkaline earth metal in an amount to provide 0.001 to 0.03 weight percent of the alkaline earth metal, the anion of the salt comprising 4 to 36 carbon atoms; heating the mixture to 100 to 180° C.; and supplying to the heated mixture a molecular oxygen-containing gas. The oxidation is conducted in the substantial absence of manganese or cobalt compounds. The oxidized wax may be esterified by reaction with an alcohol. The oxidized wax may be used in a coating composition.

Abstract: A solder paste or conductive ink printer stencil wiper apparatus combining a dual action of sucking stencil holes and simultaneously wiping the bottom of the stencil for excess solder. The apparatus includes a vacuum nozzle constructed and arranged to draw excess solder gathered in the holes of the stencil through the nozzle to a collection reservoir. The apparatus also includes a wiping element for wiping the bottom of the stencil at the same time the vacuum is sucking solder out of the stencil holes. The wiper includes a wiper fabric to wipe the bottom of the stencil. The fabric is provided on a roll, and the fabric is pulled through a series of rollers by a motor and collected on a take-up roller.
