Abstract:
An elongated steel element adapted for the reinforcement of rubber products is covered with a ternary alloy or quaternary alloy coating of copper-M-zinc. M is one or two metals selected out of the group consisting of cobalt, nickel, tin, indium, manganese, iron, bismuth and molybdenum. The copper content inside the coating ranges from 58 weight percent to 75 weight percent. The content of the one or two metals inside said coating ranges from 0.5 weight percent to 10 weight percent. The remainder is zinc and unavoidable impurities. The one or two metals are present throughout the coating. Phosphorus is present on and/or in the coating in an amount of more than 1 and less than 4 milligram per square meter of the coating. The coating further comprises one or, ore compounds which complex with the copper in the coating to form an insoluble film on its surface. Good results are obtained for steam ageing and cured humidity adhesion. Furthermore, a corresponding method for manufacturing such an elongated steel element is disclosed.

Abstract:
The present invention relates to an aqueous pour point depressant dispersion composition comprising an ethylene vinyl acetate copolymer (EVA); a dispersing agent; a polyethoxylated nonionic surfactant, a low level of hydrocarbon solvent, water; optionally one or more of an aqueous freezing point depressant, a stabilizing agent, or a basic metal substance and a method to use said composition.
Abstract:
A method for improving wear control, while maintaining or improving fuel efficiency, in an engine or other mechanical component lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and a mixture of (i) at least one carboxylic acid or metal salt of a carboxylic acid(e.g., metal stearate or stearic acid), and (ii) at least one surfactant (e.g., nonionic surfactant), as a minor components. A method for improving solubility, compatibility and dispersancy of polar additives in a lubricating oil is also provided. A lubricating oil having a composition including a lubricating oil base stock as a major component, and a mixture of (i) at least one carboxylic acid or metal salt of a carboxylic acid, and (ii) at least one surfactant, as minor components. The lubricating oils are useful in internal combustion engines.

A method for improving wear control, while maintaining or improving fuel efficiency, in an engine or other mechanical component lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition including a lubricating oil base stock as a major component, and (i) at least one transition metal salt of a carboxylic acid (e.g., zinc stearate) or (ii) a mixture of at least one transition metal salt of a carboxylic acid (e.g., zinc stearate) and at least one detergent (i.e., an alkali metal or alkaline earth metal salt of an organic acid, or an alkali metal or alkaline earth metal salt of an inorganic acid, or an alkali metal or alkaline earth metal salt of a phenol, or mixtures thereof (e.g., calcium salicylate and/or magnesium sulfonate)), as a minor component. The lubricating oils are useful in internal combustion engines.
