    摘要: Disclosed is a synthetic oil useful as a base stock for jet engine lubricating oils. The initial viscosity of the synthetic oil at 210.degree.F. is 5.0-5.5 centistokes and at -40.degree.F. is less than 13,000 centistokes. Furthermore, it does not freeze when held at -40.degree.F. for 72 hours. The oil comprises a blend of (1) a pentaerythritol ester product consisting essentially of pentaerythritol material completely esterified by straight chain C.sub.4 -C.sub.10 alkanoic acid material, and (2) a trimellitate ester product consisting essentially of trimellitic acid completely esterified by C.sub.4 -C.sub.13 alkanol material. The weight ratio of the trimellitate ester product to the pentaerythritol ester product is generally in the range from about 1:10 to about 1:1.

    摘要: During a method of evaluating a dosing operation, carried out by means of a dosing pump, for dosing a liquid medium in a vessel, filled at least partially with a gas, a pressure profile of the gas, present in the vessel, is detected at least periodically during the dosing operation. This pressure profile is compared with a desired value profile, prescribed for a control unit of the dosing pump, of the pump rate or pump output defining the dosing operation, and an evaluation result is issued in dependence on the comparison. In such case, the dosing operation is evaluated to be faulty or in need of correction when it is determined that the detected pressure profile over time with the prescribed pump rate or prescribed pump output lies outside a desired value range. A plurality of error conditions for the evaluation of the dosing operation are used, which consider the pressure development in a time window after a prescribed change in the defining pump rate or pump output.
