Abstract: Methods for activating a second application on a user device using a first application already installed and activated on the user device are described. In one embodiment the second application requests activation from the first application. The first application then authenticates a user before providing an activation response. The activation response can be requested from a remote server by the first application on behalf of the second application. The methods improve the ease of activating new software on a user device.

Abstract: Performance is improved and wear of a combustion engine is decreased by adding a solution of a compound in a combustible diluent such as methanol. The compound is the reaction product in diluent of a fluoralkyl-arylamine such as trifluoro-m-toluidine and a halide salt such as boron trifluoride. The amine group is polar and can bind with water and/or provide detergency properties. The polar group can bind to metal surfaces such as engine parts to form a highly ordered film with the low friction, non-reactive fluoralkyl groups oriented to the outside. This film protects the surface from corrosion or wear and lowers the friction between moving parts.

Abstract: Efficiency of chemical surface finishing baths for metal articles, particularly electrolytic baths for anodizing metals such as aluminum, magnesium or titanium is improved by incorporating into the bath an effective amount, typically from 0.1 to 50 grams per liter of the reaction product of a halide, such as boron trifluoride, and a trifluoro-alkaryl amine, suitably .alpha.,.alpha.,.alpha.,-trifluoro-m-toluidine.

Abstract: A protective coating for articles, and particularly titanium, is disclosed. The coating material comprises a combination of a metal halide and a fluorohydrocarbon amine. The surface of the article is preferably preliminarily cleaned by physical and/or chemical techniques, and is treated with a chemical conversion coating agent to provide an inert, microporous surface. The treated surface is then impregnated with the coating material to provide a low friction, protective surface.
