摘要： In a dual-gradient drilling apparatus, a subsea solids processing unit includes a housing, a solids processing mechanism disposed in the housing between a drilling mud inlet and a drilling mud outlet, and a flushing mechanism configured to flush the solids processing mechanism with a flushing fluid. A subsea solids processing unit may be controlled by rotating the solids processing mechanism in a forward direction and increasing a drive torque when a measured speed of the solids processing mechanism is below a desired rotation speed. The desired rotation speed may be decreased when a measured torque exceeds a selected maximum and a rotation direction of the solids processing mechanism may be reversed when the measured speed falls below a selected minimum.

摘要： A photoconductor with a charge transport layer having about 20-25% by weight of 4-N,N-bis(4-methylphenyl)-amino-benzaldehyde-N′,N′-diphenylhydrazone is in an essentially standard resin binder, such as a polycarbonate resin binder. Electrical characteristics are those of the larger amounts using conventional charge transport agents, and the larger amount of binder provides much improved wear resistance and consequently longer useful life of the photoconductor. Charge transport layers with only the foregoing bis-methyl material do exhibit moderate fatigue upon exposure to light. However, this can be overcome by adding 0.5% or less of a fluorenyl-azine as a light absorber, specifically 9-(p-diethylaminobenzylidenehydrazono)fluorene, in the charge transport layer. No antioxidant is required for electrical stability improvement.
