Abstract: A method for temperature compensating data relevant to the quality and/or condition of a fluid in use in transportation and industrial devices and/or processes. The method includes collecting and determining the temperature dependence of fluid quality and/or condition relevant data from a first fluid threshold temperature to at least a second fluid threshold temperature when change of fluid temperature is equal or greater than a preset rate, and using the determined dependence to compensate the relevant data to a standard temperature while the fluid is in use.

Abstract: A composition for lubricating an internal combustion engine includes an oil of lubricating viscosity; a predominantly linear alkylbenzenesulfonate detergent having a metal ratio of at least 8; and a combination of hindered phenolic ester antioxidant and aromatic amine antioxidant. The amount of any phenate detergent is less than 15% by weight of the total amount of detergents.

Abstract: The invention is related to a reflector lamp comprising a parabolic primary reflecting section, a parabolic or spheric secondary reflecting section joined to the primary reflecting section, and an incandescent or discharge light source. The secondary reflecting section has faceted surfaces which longitudinally extend along the surface thereof so that most or substantially all the light reflected by the faceted surfaces avoids the light source and thus the light, which would be absorbed or scattered by the light source, is minimized or substantially eliminated.
