Abstract: The invention relates to read/write methods for information hidden from visual perception and can be used to visualize hidden images of identification of an object, which provide protection against unauthorized reproduction. The surface of the object is first polished. An optically invisible marking image is formed on the polished surface by modifying at least one area of the surface, which changes the surface energy of modified sites. Said marking image is visualized by establishing a meta-stable environment in the vicinity of the aforementioned surface of the object. The marking image is produced in the form of distinguished structures formed by stable phase particles of the meta-stable environment at the sites of the object surface having different surface energy. Prior to performing a visualization process of the optically invisible marking image, the surface containing the modified areas is electrically-charged and cleaned by friction.

Abstract: Although modern diesel fuel formulations are intended to reduce emissions of diesel engines, at least some of those modern fuels tend to have relatively low lubricity levels. The control valve assemblies described herein help to minimize any increased wear that would otherwise result from the use of such low lubricity fuels by providing a valve element, a valve guide, and an insert. The valve element is received within the valve guide and is moveable between an open position and a closed position. The insert forms a first sealed interface and a second sealed interface with the valve element and the valve guide. When the valve element is in the closed position, both of the first sealed interface and the second sealed interface are engaged. When the valve element is in the open position, only one of the first sealed interface and the second sealed interface is engaged.
