  • Publication number: 20030104951
    Abstract: A problem with refrigeration systems using ammonia as the refrigerant and hydrocarbon lubricants is that the seals/gaskets of the systems have a tendency to harden and shrink. This can cause leakage of the refrigerant and eventually require disassembly of the equipment and replacement of the seals. The addition of a small amount polyether having an aromatic fragment of 6-18 carbon atoms or an aliphatic fragment of 10-22 carbon atoms can soften the seals and partially re-swell the seals solving the leakage problem and avoiding expensive maintenance costs. Alternatively a polyether of 1,2-butylene oxide which is more oil soluble than most other polyethers with a smaller Z group e.g. derived from alkanols of 1 to 9 carbon would be effective at reducing hardening and shrinkage.

  • Patent number: 5691285
    Abstract: A nontoxic and biodegradable lubricant composition for use to reduce the friction between the contact surfaces of devices which come into contact with people and animals. The lubricant composition is especially useful for application to sports equipment which comes into contact with the human body. Another application concerns the use of the nontoxic lubricant composition in connection with food processing equipment which comes into direct contact with the food substrate. The nontoxic lubricant composition includes a nontoxic oil base such as vegetable oil, preferably corn oil or olive oil, and a nontoxic solvent such as ethanol, preferably ethyl alcohol, and/or a citrus solvent, such as a terpene compound, preferably limonene. The preferred embodiment also includes limonene as a nontoxic flavoring and/or scenting agent to provide good wetting and film forming properties and a pleasant naturally occurring organoleptic fragrance and scent.

  • Patent number: 5651648
    Abstract: A method for reducing wear of ceramic cutting components during machining operations in which surface material is removed from a workpiece with reduced friction and with improved surface finish imparted to the reshaped workpiece. The method uses of cutting fluid compositions containing monomers capable of forming polymers in situ when subjected to tribological conditions (such as high temperature, pressure, and friction) existing at the contact area developed between the ceramic tool and surface of the workpiece during machining.

  • Patent number: 5605879
    Abstract: The present invention provides non-toxic, biodegradable olefin isomers which may be used as lubricants, rate of penetration enhancers, and/or spotting fluids for water-based drilling muds. When used as a spotting fluid additive, the olefin isomers preferably are supplemented with functional additives, namely emulsifiers, viscosifiers, surfactants, and/or brine. When used as lubricants and/or rate of penetration enhancers, the olefin isomers preferably are used alone or in combination with surfactants.

  • Patent number: 5563307
    Abstract: Novel fluid mixtures of specified hydrocarbons meeting an array of structural criteria are described. Linear hydrocarbons having terminal double bonds and internal segments of specified differing chain lengths separated by one or more carbon atom(s) each of which has a methylidene substituent make up one group of such compounds. Another group is alkenyl end-capped compounds of the first group. Third and fourth groups are products formed by hydrogenation of the first and second groups, respectively. The products, whether end-capped or not, and whether hydrogenated or not, have desirable lubricating properties such as suitably low pour points and/or low NOACK volatility and/or very high viscosity index and thus can be used as base oils or as components in formulating lubricants.
