Abstract: In order to reduce losses in a piston machine due to resistance of the lubricant against displacing the piston (1) furnished with at least piston ring (3, 3', 3") along the cylinder (2), and consequently to improve efficiency of operation of such machine, the invention proposes a piston ring (3, 3', 3"), which is furnished with a DLC-coating (31) on its peripheral surface (30), wherein said DLC-coating (31) contains 2 - 20%, in particular 2 - 25% of fluorine with respect to total weight of the DLC-coating (31). The invention also relates to a piston (1), which is furnished with such piston ring (3, 3', 3"), as well as to a piston machine comprising at least one piston (1) furnished with at least one piston ring (3, 3', 3") furnished with such DLC-coating (31) containing 2 - 20%, in particular 2 - 25% of fluorine with respect to the total weight of the DLC- coating (31), wherein the piston machine is either a driving machine like an internal combustion engine, or a driven machine, like a pump or a compressor.

Abstract: The object of the invention is an apparatus for determining shape and size of three-dimensional objects, which enables shortening of time required for measuring, and besides, controlling thereof may also be simplified. The apparatus comprises a desired number of measuring devices (1, 2, 3, 4), each of them consists of at least one projector (12, 22, 32, 42) as well as of at least one camera (11, 21, 31, 41). Each projector (12, 22, 32, 42) and the corresponding camera (11, 21, 31, 41) of each particular measuring device (1, 2, 3, 4) are adapted for emitting/acquiring the light of certain wavelenght, while the other cameras (12, 22, 32, 42) and projectors (11, 21, 31, 41) of the other measuring devices (1, 2, 3, 4) are adapted for emitting/acquiring the light of any other wavelenghts.

Abstract: The present invention refers to a lubricant additive, which is intended for lubricating of at least two steel machine parts, which are engaged with each other by means of sliding or rolling relative to each other, and moreover also to a lubricant containing such additive. A chemical structure of such additive is based on a linear molecule of alkane with preferably 10 to 20 carbon atoms, in which all hydrogen atoms, or all hydrogen atoms except of the terminal one, which is bound to the terminal carbon atom, are substituted with a fluorine atom or with such functional group on the basis of fluorine, which leads to oleophobicity of such substituted molecule, and wherein simultaneously at least one polar functional group is bound to at least one terminal carbon atom in order to assure adhesiveness of the additive towards the iron oxides on the surface of each lubricated machine part by simultaneously enabling sliding along the surface of the said machine part.
