Abstract: The present invention relates to compositions, kits and processes for the brightening of metal surfaces by the application of the chemical compositions. These compositions act to release hydrofluoric acid as a brightening agent. The solutions are preferably mixed during application of the brightening composition to a metal surface by mixing the solutions immediately prior to or even during application of the solution. This can be readily accomplished by mixing two solutions, one having a fluoride source and the other having a strong acid to release hydrofluoric acid from the fluoride source, the mixing occurring immediately before spray application, during spraying, or immediately after spraying of the two solutions. Mixing may be done on-site, which means that mixing is performed at the site of use, usually on the same day of use or even within a few (less than 10) minutes of use.

Abstract: A solid cleaning composition comprises a source of active oxygen agent within a binder complex. The solid is formed by a binding agent that forms the ingredients into a solid. The binding agent is a composition formed by the solidification of a mixture of an organic sequestrant, including phosphonate or aminocarboxylic acid or mixtures thereof, an active oxygen compound, and water. The solid composition can be dissolved in an aqueous solution creating an aqueous concentrate of the active oxygen at a useful concentration. The binding agent can also be used to bind additional functional materials and form a solid cleaning composition comprising the source of stabilized active oxygen as well as the additional functional material.

Abstract: A method for automatically cleaning and lubricating conveyor belt systems is disclosed. A microprocessor controlled control unit senses the movement of the conveyor belt and the presence of items, for example bottles, on the conveyor. The control unit initiates the application of lubricant, detergent and rinse water onto the conveyor according to the speed of the conveyor, the presence of items and the time passed since the previous application. If the conveyor is stationary, that is, is not in motion, no lubricant or cleaning solution is applied. If the conveyor is moving but no items are on the belt, a reduced amount of lubricant is dispensed onto the conveyor system. The conveyor cleaning and lubricating process may be carried out during normal production operations.
Abstract: The interface between a moving conveyor belt and a work piece can be lubricated using an air driven stream of finely divided droplets of a lubricant composition. Droplets of a preferred size are directed by the air stream onto the conveyor with little waste of lubricant off the conveyor. The lubricant provides a very low coefficient of friction and little or no stress cracking in the containers. Using a low pressure and low flow rate air stream in conjunction with a low flow rate liquid lubricant attains the useful particle size in the lubricant add on spray. The liquid lubricant is sheared by the effect of the air flow creating the desirable droplet size and pattern of lubricant on the conveyor.
