    Abstract: This disclosure concerns a process for preparing a synthetic hydrocarbon lubricant composition, said composition consisting essentially of a major amount of di-long-chain alkyl monocyclic aromatic hydrocarbons and a minor amount of trialkyl-substituted tetrahydronaphthalenes. The process comprises (a) alkylating an admixture of a major amount of mono-long chain alkyl monocyclic aromatic hydrocarbons and a minor amount of alkyl-substituted tetrahydronaphthalenes with linear mono-olefins containing six to 18 carbon atoms, using aluminum chloride or aluminum bromide as the catalyst, under severe reaction conditions and (b) recovering the desired product. In both the mono-long-chain alkyl aromatic and di-long-chain alkyl aromatic hydrocarbons, the long-chain alkyl groups are linear and contain six to 18 carbon atoms while the aromatic moiety is phenyl, tolyl, or xylyl.

    Abstract: A grating (22) of narrow parallel ridges (24) is formed in the surface (26) of a substrate (20) made of a hard material such as silicon dioxide. Metal (40) is deposited onto the grating (22) perpendicular to the ridges (24) at an angle of approximately 45.degree. to the surface (26) of the grating such that the metal (40) is deposited onto the top (24a) and one of the sides (24b) of the each of the ridges (24) to form generally L-shaped metal strips (12') thereon. The metal strips (12') are cut at periodic intervals along the ridges (24) to produce anisometric metal needles (12). The substrate (20) is immersed in a dielectric fluid (14), and ultrasonic energy is applied to cause the needles (12) to release from the substrate (20) into suspension in the fluid (14). The L-shape of the needles (12) makes them resistant to bending. The suspension ( 10) has birefringent properties similar to liquid crystals, but may be electrically switched at much higher speed. The index of refraction of the suspension (10) varies in accordance with the alignment of the needles (12), thereby enabling the direction and phase of an electromagnetic wave propagating through the suspension (1) to be controlled by varying the magnitude of the applied electric field.

    Abstract: A liquid dielectric composition obtained as a result of a process which comprises reacting benzene with ethylene in the presence of an alkylation catalyst to obtain an alkylation product containing largely unreacted benzene, ethylbenzene, polyethylbenzenes and heavier products, separating benzene, ethylbenzene and polyethylbenzenes from said alkylation product and thereafter recovering from said heavier products the entire fraction whose boiling point is in the temperature range of about 255.degree. to about 420.degree. C., preferably about 260.degree. to about 400.degree. C., most preferably about 268.degree. to about 400.degree. C., as said liquid dielectric composition.
