Abstract: An active suspension system is used to control the motion of a passenger seat in a high speed watercraft. A forward looking wave sensor is used in connection with a feed-forward wave impact shock predictor to determine characteristics of impending dynamic forces applied via the impact of the watercraft on waves. Information concerning the impending dynamic forces is used by a passenger seat suspension and control system to attenuate the shock effects on passengers, where such effects are characterized by large-amplitude, short-duration accelerations recurring at a low frequency and/or irregularly.

Abstract: A composition comprising a cadmium oxide and a promoter, wherein at least a portion of the promoter is present as a reduced valence promoter and methods of preparing such composition are disclosed. The thus-obtained composition is employed in a desulfurization zone to remove sulfur from a hydrocarbon stream.

Abstract: A privacy screen is configured for use with systems furniture and the like, such as post and beam arrangements that spatially partition an open office space into multiple workstations each having an interior with an opening into an adjacent space. The privacy screen is shaped to enclose a substantial portion of the opening of an associated workstation, and includes a generally flat lower portion, and a bowed upper portion that extends outwardly from the interior of the workstation to provide within the interior of the workstation a sense of spatial openness, as well as enhanced air and light influx, without detracting substantially from useable space on the opposite side of the privacy screen. The privacy screen may be constructed from a woven fabric with a single layer at the upper portion for greater visual porosity, and two layers at the lower portion for visual privacy.

Abstract: A method of substantially preventing the adsorption of polysaccharides or removing polysaccharides from clay surfaces in subterranean formations which are present as a result of contact by gravel packing, fracturing or other treatment fluids, by contacting the formation with a treatment fluid containing at least one member selected from the group consisting of tetraalkylammonium halides wherein the alkyl radical is selected from methyl, ethyl, propyl and butyl radicals and trimethylammonium halides present in an amount sufficient to substantially remove any polysaccharides adsorbed by said clays whereby the permeability of the formation is substantially maintained.
