Abstract: An emergency fuel for an internal combustion engine comprises a hydrocarbon solvent having a flash point of at least 100° F. (such as about 65-75% paraffins and about 25-35% naphthenes, or about 75-85% paraffins and about 15-25% of C7 or higher alcohols, or an aromatic solvent, or an naphthalene-depleted aromatic solvent) and a cold starting additive. The cold starting additive may be provided in an amount of less than 5,000 ppm, preferably between about 1 ppm and 150 ppm. The cold starting additive is preferably selected from peroxides, azo compounds, cyano compounds, cetane improvers, or combinations of these compounds. When the emergency fuel is added to a cold engine, including one substantially at room temperature, the engine may be easily started.
Abstract: A recording medium comprising a phosphorus-containing fluorocarbon compound is provided. The phosphorus-containing fluorocarbon compound can be used as lubricant or as an additive to a lubricant. The phosphorus-containing fluorocarbon compound can be an esterified aryl phosphorus compound, a salt thereof, or combinations thereof.

Abstract: A cutting and machining fluid applicable to both cutting and electrical discharge machining. This cutting and machining fluid comprises a water-soluble organic compound that shows an electrical resistivity of not less than 10,000 .OMEGA..cm when it is contained in deionized water having an electrical resistivity of not less than 1,000,000 .OMEGA..cm, in a concentration of from 1 to 10 % by weight, a nonionic surface active agent, or a mixture of these. The organic compound is selected from the group of ethylene glycols, propylene glycols, glycol monoethers, and polyoxyethylene fatty acid esters.
Abstract: A process is described for the production of a synthetic hydrocarbon especially useful as a base for high performance motor oils. The material is a oligomer of alpha-olefin monomer having a uniquely selective product distribution emphasizing tetramers and pentamers. This distribution is achieved through a controlled polymerization involving an initial oligomerization step followed by the delayed addition of fresh monomer to improve the yield of the desired tetramers and pentamers.
