摘要:
A method of producing an antioxidant containing compound, and in particular, an antioxidant glyceride derivative, comprises reacting a first compound with a second medium. By this reaction, a product is formed whereby an active component of the first compound, e.g., the antioxidant, is covalently incorporated into the second medium.The second medium comprises glyceride derivatives, silicones, fluorocarbons and alkoxylates containing reactive groups such as hydroxy, amino, carboxyl, ester, or amides.

Compositions of high lubrication and light coloration are disclosed in which a selected class of resins and rubbers is blended with a specified cured polybutadiene product. The cured product results from crosslinking more than 10% of vinyl bonds in a butadiene polymer having a vinyl bond content of not less 20% by mol in terms of its monomer unit. Also disclosed are solid lubricants comprising a specified fluorinated cured polybutadiene and compositions containing the solid lubricant.

An nonflammable insulating liquid is obtained by adding an emulsifying agent having a volume ratio of 1 to 3% to an insulating liquid containing a fluorocarbon liquid of at least 25% in a volume ratio to cause emulsification. In this liquid mixture, when polyol ester or dimethylcyloxane is used as the insulating liquid, an nonflammable insulating liquid that does not cause pollution or an environmental problem can be obtained. When tricresyl phosphate is used as the insulating liquid, an nonflammable insulating liquid having a dielectric constant close to that of insulating paper can be obtained. A liquid pipe for circulating a fluorocarbon emulsion in a tank is provided outside the tank, and a pump and a stirrer are connected midway along the liquid pipe to constantly stir the fluorocarbon emulsion, thereby preventing it from being separated into two layers. When a radiator is provided to the liquid pipe, the stirring system for the fluorocarbon emulsion can also serve as the cooling system.

A self-acting air bearing operable at very high speed in a non-vertical spin axis in a beam scanning optical system provides precise rotation of a rotable hologon disk. Pretreatment of the bearing surfaces with a residual boundary lubricant allows reliable operation over an extended series of start/stop cycles. The tilt of the bearing/disk assembly allows the construction of an optical system more compact than in conventional hologon beam scanning systems.
