A lockup clutch mechanism of a hydraulic transmission device includes a lockup piston that is capable of moving toward a front cover to press first and second friction plates, and a flange member that together with the lockup piston defines an engagement-side oil chamber. The length of the line extending from the line handling system to the sheave remains substantially the same length during heave compensation operations, and the point where the line takes off from the line handling system is substantially the only point of changing stress on the line. This invention also includes preconditioning fixed abrasive articles comprising a plurality of posts so that the posts have equal heights above the backing to achieve a uniform texture. A method allows red blood cells to move the separating element during decanting to ensure complete decant of the supernatant. Outside charge migrating close to the induced field is repelled away from the critical region.
