Cyclic phosphonate esters and their preparation

Abstract: Polymers containing flame retardant amounts of addition products of alkylhalogen-free esters of (1a) phosphorus acids, (1b) carboxylic acids, or (1c) sulfonic acids and (2) a bicyclic phosphite (1-alkyl-4-phospha-3,5,8-trioxabicyclo-(2,2,2)-octane), said addition products having the following group; WHERE R is lower alkyl C1-C4), preferably C1-C2, an hydroxyalkyl (C1-C4), preferably C2-C3; the addition products of (1a) or (1b) and (2); and preparation of the addition products by heating a mixture of (1a) or (1b) and (2) to an elevated temperature (e.g., 175*-300*C.).

Process for upgrading wax from Fischer-Tropsch synthesis

Abstract: The waxy liquid phase of an oil suspension of Fischer-Tropsch catalyst containing dissolved wax is separated out and the wax is converted by hydrocracking, dewaxing or by catalytic cracking with a low activity catalyst to provide a highly olefinic product which may be further converted to premium quality gasoline and/or distillate fuel.

Logging-while-drilling tool

Abstract: A logging-while-drilling tool which is adapted to be positioned within the drill string of a well drilling apparatus. The tool has a turbinelike, signal-generating valve which opens and closes at a defined rate to generate a pressure wave signal in the drilling fluid which is representative of a measured downhole condition. The tool includes spring means to normally bias the rotor away from the stator of the valve. The force constant of the spring means is greater than the pressure drop across the rotor at low flow rates but is less than the pressure drop at the flow rate at which the tool begins operation. This allows the tool to maintain a large gap between the rotor and stator prior to operation of the tool or during periods of nonoperation thereby alleviating the problem of plugging and/or jamming of the valve. During normal operation the net force holding the rotor down, i.e., the force due to hydraulic pressure drop minus the spring force, is relatively small so that the rotor will ride up over and free itself from material which may become lodged in the gap, thus alleviating jamming of the valve. Also, structural features of the rotor aid in alleviating plugging of the valve.
