| 20080283410 | Method For Producing Heavy Highly Adhesive Protective Coatings on Valve-Metal Parts By Micro-Arc Oxidation - The invention relates to electrochemistry, in particular to anodizing parts made of valve metals such as aluminium, titanium, tantalum etc and alloys thereof and can be used for producing solid heat-resistant and wear-resistant coatings for mechanical engineering. A method consists in placing a part in an electrolyte on a current-conductive holder coated with an insulating material, producing a working voltage between said part and electrolyte and raising the voltage until a micro-arc discharge is originated on the part surface. The holder of the part is externally coated with, an electroinsulating material at the air-electrolyte interface. The technical result of the invention is to produce by micro-arc oxidation heavy protective coatings which exhibit a high-hardness, have a low friction factor and a high adhesion to a base material on the parts made of the valve metals or alloys thereof. | 11-20-2008 |

| 20110154725 | AGENT FOR INCREASING THE OCTANE NUMBER OF A GASOLINE AUTOMOBILE FUEL - The invention relates to an agent for increasing the octane number of a gasoline automotive fuel, which agent is a combination of alcohol and a product of reaction between a carbonyl compound and a compound containing at least two hydroxyl groups enabling to form cycles with carbonyl compounds, or is the mixtures of the above mentioned products. In the preferred variant, mono- or oligosaccharides or diatomic, triatomic or polyatomic alcohols are used as the compounds containing at least two hydroxyl groups enabling to form cycles with carbonyl compounds. Pentoses, preferably xylose or arabinose or hexose, substantially glucose, and the mixtures thereof are used as the monosaccharides. Glycols, for example, ethylene glycol are used as diatomic alcohols, glycerin is used as triatomic alcohols and erythritols, for example, pentaerythritol are used as polyatomic alcohols. The compound relating to lower aldehydes or lower ketones, for example, formaldehyde, acetaldehyde, acetone, methylethylketone, diethylketone or cyclohexane are used as a carbonyl compound. The alcohols are in the form of aliphatic alcohols containing up to five carbon atoms, substantially ethanol. The inventive gasoline automotive fuel means a gasoline or an alcohol-gasoline composition. | 06-30-2011 |
