Abstract: Treating fluid compositions for use in hydrocarbon recovery operations from subterranean formations are described, as well as methods for their preparation and use. In particular, treating fluid compositions are described which comprise a liquid, a crosslinkable organic polymer material that is at least partially soluble in the liquid, a crosslinking agent that is capable of increasing the viscosity of the treating fluid by crosslinking the organic polymer material in the liquid, and a crosslinking modifier additive which can delay or accelerate the crosslinking of the treating fluid composition. Such compositions may be used in a variety of hydrocarbon recovery operations including fracturing operations, drilling operations, gravel packing operations, water control operations, and the like.

Abstract: La présente invention concerne un ensemble d'ouverture de mécanisme opérationnel d'un appareil de commutation électrique, la broche d'arrêt/actionnement de l'ensemble de basculement ayant été séparée entre une broche d'actionnement et une broche d'arrêt. Grâce à la séparation des fonctions de la broche d'arrêt/actionnement en broches séparées, la broche d'actionnement peut maintenant être située au point d'articulation de la liaison associée. En outre, la broche d'actionnement et la broche d'arrêt sont maintenant disposées au-dessus d'un ensemble berceau par opposition à une liaison allongée. L'ensemble berceau supporte également l'une des liaisons d'ensemble de basculement. Donc, la rotation de l'ensemble berceau entraîne le mouvement de l'ensemble de basculement. L'ensemble d'ouverture du mécanisme opérationnel est configuré de telle sorte que, quand un ensemble plaque de verrouillage associé est libéré, l'ensemble berceau tourne de telle sorte que l'ensemble de basculement soit éloigné d'un dispositif de fermeture de l'ensemble de fermeture.

Abstract: A method (300) for generating a sine and cosine of an input angle (.SLZERO.102). The method involves decomposing .SLZERO.102 to an octant or quadrant, a coarse angle (A), and a fine angle (B), determining cos(A), and determining sin(A). The method also involves decomposing cos(A) and sin(A) to a most significant word (MSW) and a least significant word (LSW). The method further involves computing an approximation of 1-cos(B), an approximation of sin(B), and a plurality of products (P1,..., P4) using the MSWs and approximations. The method involves computing approximations of cos(.SLZERO.'102) and sin(.SLZERO.'102) using the values for cos(A), sin(A), and P1,..., P4. The method involves scaling the approximations of cos(.SLZERO.'102) and sin(.SLZERO.'102) to a desired resolution.

Abstract: An accelerated vapor recompression apparatus (10) converts incoming flow (35a) to a concentrate (35e) by developing a concentration profile (146) within a tank (30) holding a liquid (23) containing dissolved solids. The resulting curve (160) of saturation temperature of the stratified liquid (23), such as a brine (23) or other material (23), moves away from the curve (162) corresponding to fully mixed conditions. The shift (174, 180) in saturation temperature results in increased boiling without increased energy from a heater (70) or compressor (50). A method (90, 200) of control of the system provides interventions (203, 204, 205, 206) at different levels (92, 94, 96, 98) of control, ranging from mass flows (35) to work of a compressor (50), heat from a heater (70), and a predictive processing (215) of feedback (217) for controlling commands (216) algorithmically.

Abstract: In a method for recovering phosphorus-containing alternative fuels in cement clinker production, the alternative fuels are thermolyzed using waste heat from the cement clicker production process in a thermolysis reactor different from a rotary kiln of the cement clinker production process, the energy thereby released is supplied to the cement clinker production process and the thermolysis residues of the phosphorus-containing alternative fuels are discharged from the thermolysis reactor, and so the thermolysis residues of the phosphorus-containing alternative fuels are mixed in the thermolysis reactor with cement kiln bypass products as halogen carriers and the heavy-metal halides produced are drawn off.
