Abstract: A novel hydraulic fluid composition for application to drilling equipment is described herein. These hydraulic fluid compositions permit effective monitoring or controlling well-head pressure of a well during drilling on land or offshore. The hydraulic fluid compositions prevent uncontrolled flow of gas, oil, or another well fluid out of an underground formation during a drilling or extraction process when applied to the drilling equipment. Accordingly, provided is a hydraulic fluid concentrate which contains a water-soluble phosphate ester and a sulfide compound containing at least one S-S linkage, at least 10 carbon atoms and at least one terminal carboxylate group, wherein the S-S linkage bridges two alkyl groups. Additional components can be added to the concentrate and include one or more alkaline compound, one or more dicarboxylic acid or salt thereof, a water-soluble corrosion inhibitor, a water-soluble biocide, a pour point depressant, and water, ethylene glycol, or a combination thereof. The concentrate is then further diluted by the customer for use as described herein. Particularly, these compositions are effective in reducing seawater corrosion of a metal in contact with the hydraulic fluid composition, reducing bioaccumulation in oil drilling equipment contacted with the hydraulic fluid composition, and have low toxicity to sea life.

Abstract: Complex greases of overbased alkaline earth metal carboxylates are prepared by reacting an overbased alkaline earth metal salt of a fatty acid, wherein the alkaline earth metal salt has an alkaline earth metal content of at least 14.5% and a non-volatile matter content of at least 95% with conversion agents to form a grease precursor. The grease precursor is then reacted with complexing agents to form a predominantly vaterite containing non-Newtonian modified overbased metal carboxylate complex grease.

Abstract: The present invention relates to the lubrication and/or water repellency of gears used, in particular, during the practice of winter sports.
A surface tension of the lubricant agent lower than that of the gear implies an increase of water repellency and thus, an improvement of the capability of removing the water film forming between the snow and the bottom lining of the gear during the reciprocal movement. In fact, this water film increases the adherence of the bottom lining to the snow and reduces the sliding thereof.
Such lubricating action is achieved by the use of the compound having the described formula, pure or in a mixture.

Abstract: The invention relates to an engine part coating created from polysiloxanes, said coating comprising one or more of the following compounds: cross-linked polymer made of polysiloxanes; silica; silicon-carbide-oxide; and silicon nitride. The coating can be obtained by the method steps of a) dispersing polysiloxane in a lubricant; b) bringing the lubricant into contact with certain surface areas inside an engine; c) subjecting the polysiloxane to such a temperature that it forms a silicon-containing coating on the contacted engine parts. The polysiloxane can be added to the motor oil as an additive or can be mixed directly with the fuel of a combustion engine.
