  • Patent number: 9840310
    Abstract: A seat module suspension system for a high-speed water vessel including a guide assembly for permitting a range of substantially vertical travel of the seat module, an air shock within the guide assembly for resiliently suspending the seat module; and a support assembly extending for impeding athwart movement of a forward projecting portion of the seat module. The support assembly includes a spar pivotally mounted at one end the base of the guide assembly and pivotally mounted at the other end to a mount attached to the underside of the forward projecting portion and configured to permit fore and aft movement, so as to accommodate substantially vertical movement of the seat module. The system also includes a second air shock connected to the support assembly to impede the fore and aft movement and thus support the forward projecting portion of the seat module.

  • Patent number: 9422039
    Abstract: A suspension system for passenger modules or marine platforms used with high-speed boats, the suspension system including a shock absorbing assembly, for supporting the marine platform relative to the vessel. The marine platform is attached to the vessel via an assembly of pivoting spars in which the vessel attachment locations are spaced athwart a greater distance than the marine platform, and the attachment of some spars permits relative fore and aft movement between the spars and the marine platform or the vessel to accommodate pitch. The suspension system may include components for attenuating motion associated with roll.

    Abstract: A suspension system for passenger modules or marine platforms used with high-speed boats, the suspension system including a shock absorbing assembly, for supporting the marine platform relative to the vessel. The marine platform is attached to the vessel via an assembly of pivoting spars in which the vessel attachment locations are spaced athwart a greater distance than the marine platform, and the attachment of some spars permits relative fore and all movement between the spars and the marine platform or the vessel to accommodate pitch. The suspension system may include means for attenuating motion associated with roll.

  • Patent number: 9016226
    Abstract: A suspension system for passenger modules used with high-speed boats, the suspension system including a shock absorbing assembly, for supporting the passenger module relative to the vessel. The passenger module is attached to the vessel via an assembly of pivoting spars in which the vessel attachment locations are spaced athwart a greater distance than the passenger module attachment locations. The suspension system may include means for resisting relative lateral movement (e.g. a panhard rod or a Watt's linkage) and for attenuating motion associated with pitch and roll.

  • Publication number: 20140076787
    Abstract: A method and apparatus in accordance with the present invention comprising a decomposable compound such as hydrogen peroxide as a primary additive to generate bubbles within a fluid medium such as an aqueous slurry of tar sands. The size range of bubbles, density (number per unit volume) of bubbles, and rate of in situ generation of bubbles are controlled by controlling process variables including but not limited to temperature, concentration of decomposable compound, residence time, pressure, viscous shear, ratio of water to solids, pH of the slurry, shape of the separation vessel, and addition of one or more secondary process additives.

  • Publication number: 20110030601
    Abstract: A suspension system for passenger modules used with high-speed boats, the suspension system including a shock absorbing assembly, for supporting the passenger module relative to the vessel. The passenger module is attached to the vessel via an assembly of pivoting spars. The spars may be configured such that the passenger module moves from an upper at-rest no-load position towards a bottom loaded position, the passenger module tilts. The amount of such tilt may be adjustable. The suspension system may have include means for resisting relative lateral movement (e.g. a panhard rod or a Watts linkage) and an anti-sway device.
