摘要： The bore of the ring has workings (1a) suitable to act as a grease reserve at the friction area. A self-lubricating coating (3) with low wettability is applied to the entire surface of the said bore, including in the workings (1a) suitable to act as a grease reserve, such that after wearing of the layer of self-lubricating coating at the friction surface of the bore, the difference in wettability between the said friction surface and the workings still having the coating, enables the grease to be drawn out of the said workings in order to lubricate the said friction surface.

摘要： A compressor system includes a compressor including a compressor inlet, a compressor outlet, and a bearing assembly, the compressor configured to compress a heat transfer fluid. An additive dispenser is fluidly coupled to the compressor upstream of the bearing assembly. The additive dispenser is configured to controllably release a volume of an additive material into the heat transfer fluid, the additive material configured to lubricate the bearing assembly. A method of lubricating a bearing assembly of compressor includes locating a volume of additive material at an additive dispenser fluidly coupled to a compressor, dispensing a portion of the additive material into the flow of heat transfer fluid at a selected time, flowing the heat transfer fluid containing the additive material to a bearing assembly of the compressor, and lubricating the bearing assembly of the compressor with the additive material.

摘要： A process for converting a molten polymeric material is provided. The process includes effecting disposition of a molten polymeric material, having at least one carbon-carbon double bond, in sufficient proximity to a catalyst material within a reaction zone, to affect a reactive process that effects generation of a reaction product. The reactive process effects cleaving of at least one carbon-carbon double bond. The catalyst material includes [Fe—Cu—Mo—P]/Al2O3 prepared by binding a ferrous-copper complex to an alumina support to generate an intermediate material and reacting the intermediate material with a heteropolyacid.

摘要： The invention relates to devices for purifying hydraulic and dielectric fluids (oils and fuels) of mechanical impurities and dissolved and dispersed water. It could be used in any fields where clean and contaminated fluids are used. The apparatus for reclaiming hydraulic and dielectric fluids comprises a vacuum tank with an atomizer, a vacuum pump, a dielectric fluid feed pump and dielectric fluid removal pump, all of said pumps being connected to the tank by pipes, and an electric filter, wherein the atomizer is disposed in the lower part of the vacuum tank, is arranged vertically with a spray member oriented upward and consists of a T fitting with a lower inlet for fluid and with a lateral inlet for air, a mixing chamber disposed above the T fitting, and a spray member with a nozzle, said spray member being disposed above the mixing chamber, and the electric filter comprises a housing with an inlet pipe and outlet pipe, a high-voltage power supply, a composite unit disposed inside the housing and consisting of current-carrying plates and dielectric spacers with apertures for current-carrying and heavy-duty fastening elements, a front plug and rear plug, and is current-carrying and heavy-duty fastening elements, wherein the surface of the current-carrying plates is provided with a porous ceramic dielectric coating. The technical result is increasing the efficiency of purifying and reclaiming dielectric fluids; increasing the useful volume of the vacuum tank without increasing the dimensions thereof; reducing the dispersivity of the fluid sprayed from the atomizer; simplifying the design; stabilizing the electromagnetic field of the electric filter; increasing the surface area of the electric filter by creating a developed surface of current-carrying filter elements without changing filter size and mass; improving reliability and ease of use; and reducing materials consumption.
