Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
191 words
A high temperature lubricating composition consisting essentially of (a) a high temperature liquid lubricant (b) a surfactant having an HLB number below 7 and which is soluble in the liquid lubricant, (c) a finely divided, solid, high temperature lubricant selected from the group consisting of graphite, molybdenum disulfide, mica, boron nitride and potassium iodide, (d) water, (e) a water soluble component selected from the group consisting of a low molecular weight alcohol, glycol, amine, and inorganic salt, elements (a), (b), and (c) being present in a continuous phase and elements (d) and (e) being present as a discontinuous phase dispersed in the continuous phase, with the continuous phase making up 55 to 90% by weight of the composition and the discontinuous phase making up the remainder and in which the surfactant is present in an amount within the range of up to 20% by weight of the continuous phase, the finely divided high temperature solid lubricant is present in an amount within the range of 10-30% by weight of the continuous phase and the water soluble component is present in an amount up to 25% by weight of the discontinuous phase.
Claim 2
Dependent Claim
191 words
A high temperature lubricating composition consisting essentially of (a) a high temperature liquid lubricant (b) a surfactant having an HLB number below 7 and which is soluble in the liquid lubricant, (c) a finely divided, solid, high temperature lubricant selected from the group consisting of graphite, molybdenum disulfide, mica, boron nitride and potassium iodide, (d) water, (e) a water soluble component selected from the group consisting of a low molecular weight alcohol, glycol, amine, and inorganic salt, elements (a), (b), and (c) being present in a continuous phase and elements (d) and (e) being present as a discontinuous phase dispersed in the continuous phase, with the continuous phase making up 55 to 90% by weight of the composition and the discontinuous phase making up the remainder and in which the surfactant is present in an amount within the range of up to 20% by weight of the continuous phase, the finely divided high temperature solid lubricant is present in an amount within the range of 10-30% by weight of the continuous phase and the water soluble component is present in an amount up to 25% by weight of the discontinuous phase.
