Composite microsphere and lubricant mixture

Claim 2

A composite mixture comprising: spherical objects and means for lubricating said spherical objects for low-friction sliding and rolling contact with each other; wherein said spherical objects and said lubricating means are mixed together to form the composite mixture; wherein said lubricating means is present on the exterior surface of essentially all of said spherical objects, but in a quantity less than would cause dispersion of said spherical objects in said lubricating means sufficient to significantly physically separate said spherical objects from each other and thereby reduce the sliding and rolling contact of said spherical objects with each other; wherein said lubricating means is lubricous, serves to reduce the coefficient of friction between contacting spherical objects, and does not prevent sliding and rolling of said spherical objects with respect to each other; wherein said spherical objects within said mixture are movable in low-friction sliding and rolling contact with each other in all three dimensions; wherein said lubricating means comprises an element selected from the group consisting of soap and detergent; wherein the composite mixture flows and shears in response to a deforming pressure exerted on it, said flow and shear being accomplished by said spherical objects moving in rolling and sliding contact with each other; and wherein the composite mixture ceases to flow and shear when the deforming pressure is terminated.

Claim 3

A composite mixture as recited in claim 1 wherein at least one of said spherical objects comprises an inert gaseous interior.

Claim 4

A composite mixture as recited in claim 2 wherein the rigid outer shells of said spherical objects are made from material selected from the group consisting of plastic, glass, metal, carbon, mineral, and quartz.

Claim 5

A composite mixture as recited in claim 1 wherein said spherical objects are less than 2000 microns in diameter.

Claim 6

A composite mixture as recited in claim 1 wherein said spherical objects are of diameters ranging from 5 to 200 microns.

Claim 7

A composite mixture as recited in claim 1 wherein said spherical objects are of diameters ranging from 10 to 70 microns.

Claim 8

A composite mixture as recited in claim 6 wherein said composite mixture flows and shears under light pressure and ceases to flow and shear when pressure is removed.

Claim 9

A composite mixture as recited in claim 6 wherein said composite mixture maintains its essential performance with temperatures in the temperature range of 0 degrees to 120 degrees Fahrenheit.

Claim 10

A composite mixture as recited in claim 1 wherein said spherical objects comprise a rigid outer shell and a gaseous interior.

Claim 11

A composite mixture as recited in claim 9 wherein said lubricant maintains lubricousness with changes in temperature.

Claim 12

A composite mixture as recited in claim 9 wherein said composite mixture resists breaking down over time.

Claim 13

A composite mixture as recited in claim 1 wherein said lubricating means further comprises a lubricant selected from the group consisting of water-based, petroleum-based, silicone-based, vegetable-based, and mineral-based lubricants.

Claim 14

A composite mixture as recited in claim 1 wherein said composite mixture has a thermal mass less than 0.7 calories per cubic centimeter per degree Celsius.

Claim 15

A composite mixture as recited in claim 1 wherein said composite mixture has a coefficient of heat transfer less than 0.25 btu per hour per foot per degree Fahrenheit.

Claim 16

A composite mixture as recited in claim 1 further comprising antifreeze.

Claim 17

A composite mixture comprising: spherical objects comprising an outer shell and an inert atmosphere sealed within the outer shell, said spherical objects being less than 2000 microns in diameter, and means for lubricating said spherical objects; wherein said lubricating means comprises an element selected from the group consisting of soap and detergent; wherein said lubricating means is lubricous, serves to reduce the coefficient of friction between contacting spherical objects, and does not prevent sliding and rolling of said spherical with respect to each other; wherein said lubricating means is present on the exterior surface of essentially all of said spherical objects, but in a quantity less than would cause dispersion of said spherical objects in said lubricating means sufficient to significantly physically separate said spherical objects from each other such that more than a thin film of lubricant is interposed between spherical objects and preventing the sliding and rolling contact of said spherical objects with each other; wherein said spherical objects and said lubricating means are mixed together to form the composite mixture; wherein said spherical objects within said mixture are movable in low-friction sliding and rolling contact with each other in all three dimensions; wherein said composite mixture exhibits little memory for shape; wherein said spherical objects are made from material selected from the group consisting of plastic, glass, metal, carbon, mineral, and quartz; wherein said lubricant maintains lubriciousness with changes in temperature; wherein said composite mixture has a low thermal mass and a low coefficient of heat transfer; wherein the composite mixture flows and shears in response to a deforming pressure exerted on it, said flow and shear being accomplished by said spherical objects moving in rolling and sliding contact with each other; wherein said composite mixture has a low shearing force threshold when rapidly sheared; and wherein said composite mixture resists separating into its constituent components over time.

Claim 18

A composite mixture comprising: spherical objects comprising an outer shell and an inert atmosphere sealed within the outer shell, said spherical objects being less than 2000 microns in diameter, and means for lubricating said spherical objects; wherein said lubricating means comprises an element selected from the group consisting of soap and detergent; wherein said lubricating means is lubricous, serves to reduce the coefficient of friction between contacting spherical objects, and does not prevent sliding and rolling of said spherical with respect to each other; wherein said lubricating means is present on the exterior surface of essentially all of said spherical objects, but in a quantity less than would cause dispersion of said spherical objects in said lubricating means sufficient to significantly physically separate said spherical objects from each other such that more than a thin film of lubricant is interposed between spherical objects and preventing the sliding and rolling contact of said spherical objects with each other; wherein said spherical objects and said lubricating means are mixed together to form the composite mixture; wherein said spherical objects within said mixture are movable in low-friction sliding and rolling contact with each other in all three dimensions; wherein said composite mixture exhibits little memory for shape; wherein said spherical objects are made from material selected from the group consisting of plastic, glass, metal, carbon, mineral, and quartz; wherein said lubricant maintains lubriciousness with changes in temperature; wherein said composite mixture has a low thermal mass and a low coefficient of heat transfer; wherein the composite mixture flows and shears in response to a deforming pressure exerted on it, said flow and shear being accomplished by said spherical objects moving in rolling and sliding contact with each other; wherein said composite mixture has a low shearing force threshold when rapidly sheared; and wherein said composite mixture resists separating into its constituent components over time.

Claim 19

A composite mixture as recited in claim 16 further comprising antifreeze.
