    Abstract: A lubricant coating for laser printer wiper blades is a solution applied to a laser printer wiper blade before install that reduces friction between the wiper blade and the photoconductor drum of a laser printer in order to reduce wear, prevent damage and increase life of the wiper blade and photoconductor drum. A leveling and wetting agent ensures uniform application and reduces coating defects. An anti-wear agent reduces friction and acts as an electrical insulator. A friction reducing agent also reduces friction and acts as an electrical insulator. An evaporation promoting agent aids in evaporation of unnecessary material after application to a wiper blade. A coating enhancing agent increases the hardness of the coating and provides assistance in adherence of the solution to the wiper blade. Deionized water acts as a carrier. The solution is mixed in a high shear mixture.

  • Publication number: 20110285124
    Abstract: A film-forming lubrication composition for make-up of threaded connections, intended to cover at least one threading (FE, FI) and a make-up abutment (BVM, BVF) of a threaded element (EM, EF) of a component (T2, T1) of a threaded tubular connection (JF) with a solid state film which adheres to the threading (FE, FI) and to said make-up abutment (BVM, BVF), said make-up abutment (BVM, BVF) being intended to bear against another abutment (BVF, BVM) of another component (T1, T2) of said threaded tubular connection (JF) during the terminal make-up phase, and said lubrication composition comprising a matrix. The matrix further comprises at least one rheoresistant material selected so as to endow said composition, as a complement to lubrication, with a shouldering torque which is at least equal to a threshold value.

  • Patent number: 8047506
    Abstract: The present invention is directed to an apparatus for distributing a cable-pulling composition onto a cable as it is being pulled through a conduit. In one embodiment, the cable pulling composition is a block of an enhanced composition, e.g., consisting essentially of boron nitride that facilitates the pulling of cables through conduits. The invention further relates to a method for pulling cables through conduits by applying an effective amount of boron nitride composition onto the cable surface through the use of the cable-pulling apparatus of the invention.

  • Patent number: 7994105
    Abstract: A combination nano and microparticle treatment for engines enhances fuel efficiency and life duration and reduces exhaust emissions. The nanoparticles are chosen from a class of hard materials, preferably alumina, silica, ceria, titania, diamond, cubic boron nitride, and molybdenum oxide. The microparticles are chosen from a class of materials of layered structures, preferably graphite, hexagonal boron nitride, magnesium silicates (talc) and molybdenum disulphide. The nano-micro combination can be chosen from the same materials. This group of materials includes zinc oxide, copper oxide, molybdenum oxide, graphite, talc, and hexagonal boron nitride. The ratio of nano to micro in the proposed combination varies with the engine characteristics and driving conditions. A laser synthesis method can be used to disperse nanoparticles in engine oil or other compatible medium.
