  • Patent number: 10722746
    Abstract: An exercise device having a sled or wheelbarrow configuration comprises a frame that is pushed across a support surface by a user. The frame carries a wheel that movably supports the frame in the wheelbarrow configuration and at least one skid that movably supports the frame in the skid configuration. A pair of handles is selectively repositionable on the frame from a vertical orientation used in the sled configuration and a horizontal orientation used in the wheelbarrow configuration to quickly and easily convert the device between its different configurations. The frame has a carriage that supports a plurality of exercise weight members with the carriage being movable in a fore-and-aft direction on the frame for changing the effort required from the user to push the frame.

  • Publication number: 20150101420
    Abstract: A skeg mounts from the stern of a towing vessel and extends below the waterline. A channel in the skeg protects cables for steamers and a source (e.g., air gun array) of a seismic system deployed from the vessel. Tow points on the skeg lie below the water's surface and connect to towlines to support the steamers and the source. A floatation device supports the source and tows below the water's surface to avoid ice floes or other issues encountered at the water's surface. Seismic streamers have head floats supporting the streamers. Each of the floats has adjustable buoyancy preconfigured to counterbalance the weight in water of the towed component that the float supports. Acoustic signals from a transceiver at the vessel find locations of the towed components. A towed fish at a lower level than the towed components also uses acoustic signals with a transceiver to further refine the locations of the towed components.

  • Patent number: 6439954
    Abstract: A weight transferring sled toy for simulating a weight transfer sled used in truck and tractor pulls. The weight transferring sled toy includes a main body portion that has a main body base and a pair of tracks that extend upward from the main body base. A pair of wheels are coupled to a rear portion of the main body portion. An axle extends between the wheels and is coupled to the rear portion of the main body portion. An axle gear is coupled to a medial portion of the axle. A bar extends between a forward portion of the tracks. A drive chain extends between the bar and the axle gear such that rotation of the axle gear rotates the drive chain. A weight sled is positionable on the tracks. The weight sled has a hook member for engaging the drive chain whereby the weight sled is moved along the tracks when the wheels rotate and the hook member is engaged to the drive chain.
