HATTA-29 APPLICATION FOR LETTERS PATENT FOR COMPOSITION SUITABLE FOR MECHANICAL POWER TRANSMISSION AND PROCESS FOR OPERATING TRACTION DRIVES ABSTRACT OF THE DISCLOSURE The disclosure relates to a composition suitable for use in mechanical power transmission devices. It has as its prin- cipal component a hydrocarbon oil which has from 19 to 30 carbon atoms, inclusive, and three six-membered carbocyclic rings and consists of a mixture of compounds having the following formula: Image (I) wherein R1 is a divalent straight or branched chain radical CyH2y where y is an integer of l through 3; R2 is a straight chain radical CzH2z where z is an integer of l through 3; R3, R4, and R5 are the same or different alkyl groups having from 1 through 4 carbon atoms; ? , m, and n each is an integer from zero through 3; and x is zero or 1; and wherein rings A and B are hydrogenated benzene rings and ring C is a hydrogenated benzene ring when X is 1 and a hydrogenated benzene ring or a cyclohexane ring when X is zero said hydrogenated benzene rings being saturated with hydrogen to the extent of at least 80% but less than 100% of the theoretical, and the composition can additionally contain one or more of an antioxidant, a rustproof- ing agent, a viscosity index improver, and antifoaming agent.
