  • Gun lubricant
    Patent number: 10519391
    Abstract: A lubricant for a gun or other metal devices, including a composition and method of treating a gun to maintain optimum operative condition. The lubricant serves many purposes, beyond simply allowing parts to move with less resistance. In addition to reducing friction between moving parts of the gun, the gun oil of the present disclosure disperses to coat the metal parts of the gun thoroughly and evenly, remains moist for an extended period of time, and when dry, forms a thick layer that protects the metal components of the gun from wear and rust. The lubricant includes a 4-cycle synthetic motor oil, an oil stabilizer, and a 2-cycle motor oil.

  • Base stocks and lubricant compositions containing same
    Patent number: 10400185
    Abstract: Systems and methods are provided for block operation during lubricant and/or fuels production from deasphalted oil. During “block” operation, a deasphalted oil and/or the hydroprocessed effluent from an initial processing stage can be split into a plurality of fractions. The fractions can correspond, for example, to feed fractions suitable for forming a light neutral fraction, a heavy neutral fraction, and a bright stock fraction, or the plurality of fractions can correspond to any other convenient split into separate fractions. The plurality of separate fractions can then be processed separately in the process train (or in the sweet portion of the process train) for forming fuels and/or lubricant base stocks. This can allow for formation of unexpected base stock compositions.
