  "title": "Oil additive",
  "abstract": "An additive composition to be incorporate with an oil base such as a petroleum-based lubricating oil. The additive includes the combination of a metal carboxylate, containing a metal such as bismuth, copper, zinc or manganese, and a carboxylic acid in a solvent system. The additive when incorporated with the oil base provides increased corrosion resistance, decreases \"washout\" capabilities of the oil from the lubricated metal and provides a minimum change of viscosity over a wide range of temperature.",
  "claims": [
    "1. An additive to be incorporated with an oil base, consisting essentially of by weight percent 0.2% to 99.5% of a carboxylate premix, 0.02% to 20% of a carboxylic acid, 0% to 95% of an oil, and 0% to 98.8% of a solvent, said carboxylate premix composed of 18% to 95% by weight of a metal carboxylate wherein a metal of the metal carboxylate is bismuth and whereby the carboxyl radical contains from 6 to 16 carbon atoms and 82% to 5% by weight of a liquid organic carrier which is miscible with the carboxylate wherein the carrier is neodecanoic acid.",
    "2. The additive of claim 1, wherein said solvent is selected from the group consisting of an aliphatic solvent and an aromatic solvent, said solvent having a flash point greater than 115° F.",
    "3. The additive of claim 1, and including up to 1.0% defoaming agent.",
    "4. The additive of claim 1, and including up to 1.5% of a rust and oxidation inhibitor.",
    "5. The combination of claim 1, wherein the metal carboxylate is bismuth neodecanoate.",
    "6. The combination of claim 1, wherein the metal carboxylate is bismuth 2-ethylhexanoate.",
    "7. An additive to be incorporated with an oil base, consisting essentially of weight percent 0.2% to 99.5% of a carboxylate premix, 0.02% to 20% of a carboxylic acid, 0% to 95% of an oil, and 0% to 98.8% of a solvent, said carboxylate premix composed of 18% to 95% by weight of a metal carboxylate wherein a metal of said metal carboxylate is zinc and whereby the carboxyl radical contains from 6 to 16 carbon atoms and 82% to 5% by weight of a liquid organic carrier which is miscible with the carboxylate wherein said carrier is mineral oil.",
    "8. A combination of an oil and an effective amount of an additive, the combination comprising: the oil; and the additive consisting essentially of by weight from 0.5% to 99.5% of a metal carboxylate premix, 0.02% to 20% of a carboxylic acid containing from 6 to 16 carbon atoms, 0% to 95% of oil, 0% to 98.8% of a solvent, 0% to 1.0% of a defoaming agent and 0% to 1.5% of a corrosion inhibitor, said metal carboxylate premix comprising from 5% to 95% by weight of a metal carboxylate containing a metal selected from the group consisting of zinc, bismuth, and manganese, and the balance of the premix being a liquid organic carrier miscible with said metal carboxylate, said metal carboxylate having a carboxyl radical containing from 6 to 16 carbon atoms, said carrier having a flash point above 115° F. and a viscosity of 55 SUS to 2000 SUS.",
    "9. The combination of claim 8, wherein said oil is a petroleum based lubricating oil.",
    "10. The combination of claim 8, wherein the oil is a food grade oil.",
    "11. The combination of claim 8, wherein the carboxylic acid is naphthenic acid.",
    "12. The combination of claim 8, wherein the oil is selected from the group consisting of petroleum oil, synthetic oil, vegetable oil and silicone oil.",
    "13. The combination of claim 8, wherein the carrier is selected from the group consisting of mineral oil, mineral spirits, neodecanoic acid, octanoic acid, d-limonene, and mixtures thereof."
