    摘要： A refurbishment process for a volumetric screw compressor of the ‘oil-free’ type, which comprises a male rotor and a female rotor, is described. The process comprises visually checking the wear condition of the rotors, treating their surface for removing the previous coating, and applying a new coating on the surface. The composition of the coating applied on the surface of the rotors consists of the following materials: MaterialAmount (g) Polytetrafluoroethylene750 ÷ 850 (954G 303 C Teflon, DuPont) Amorphous graphite powder300 ÷ 400 Thinner for spray cleaning apparatuses200 ÷ 270 (8595 thinner, DuPont) Methyl ethyl ketone (MEK)170 ÷ 220 Cellosolve acetate coating additive200 ÷ 300 (Syn Fac 800 resin)

    摘要： One aspect of the present invention relates to a method for modifying one side of a PTFE membrane by using HFCVD to deposit a PTFE film on one side of the PTFE membrane. The precursor fluorocarbon gas is preferably hexafluoropropylene oxide, which upon pyrolysis under HFCVD conditions forms reactive CF2 species. The present invention also relates to a modified PTFE membrane having a PTFE film on only one side, wherein the PTFE film has a porosity of greater than about 30% and a dangling bond density of less than about 1018 spins/cm3. The invention further provides a method of filtering a liquid or gas or a mixture of the two, comprising passing the liquid or gas or mixture of the two through the modified PTFE membrane of the present invention.

    摘要： A method and apparatus for coating a fastener with head and shank portions is disclosed. The invention includes the steps of and apparatus for transferring the fasteners from a feed mechanism such that the fasteners are positioned for coating. The fasteners are then conveyed through a plurality of operating stations, beginning with a heating station where the shank portions of the fasteners are heated. Subsequently, at a material applying station, a coating material is applied to the heated shank portions. A preferred embodiment of the method and apparatus of the present invention includes using a magnetic holder to carry the fasteners horizontally by their head portions, where fasteners are centered by a rotating wheel, heating the shank portion to a temperature above the melting point of the applied material and applying the material to the heated shank portion to form a coating thereon. The magnetic holders are part of an endless traveling belt that rotates continually. The fastener carriers have teeth that engage a rack to rotate the fasteners. A conveyor provides added air cooling for the coated fasteners, which can continue to be rotated. Also disclosed is a transfer wheel with two sets of notches that is synchronously coupled to the traveling belt for placing and aligning fasteners on the belt for coating. Uncoated areas on the fasteners may be detected via sensors present beyond the powder spray station which may include a plurality of spray nozzles.

    摘要： A process for converting the lubrication system of an internal combustion engine from a system using an oil containing metallic and chemical friction modifiers, to an oil substantially devoid of such modifiers. A solvent and a perfluoroethylene resin are added to the existing oil in the lubrication system of the engine in sufficient amounts to remove oil residue or varnish from the surfaces within the lubrication system, and to coat the surfaces with perfluoroethylene resin. The oil, solvent and perfluoroethylene resin are circulated throughout the lubrication system for a time sufficient to remove oil residue or varnish from the surfaces within the lubrication system of the engine, and to coat the surfaces with perfluoroethylene resin. The oil, solvent and residual perfluoroethylene resin are evacuated from the lubrication system of the engine, and an oil substantially devoid of metallic and chemical friction modifiers is added to the lubrication system of the engine.
