  • Patent number: 8302549
    Abstract: A boat stabilizer that is attachable to the anti-cavitation plate or other structure of the lower drive unit of a boat motor without permanently modifying the structure of the anti-cavitation plate or other structure is provided. The shape and size of the boat stabilizer causes the stabilizer to effectively harness and control the thrust energy generated by the propeller resulting in improved thrust and fuel efficiency. Due to various features, the drag associated with the boat stabilizer is kept to a minimum. Finally, decals and other decorative elements are integrally embedded into the top surface of the inventive boat stabilizer using in-mold decoration (“IMD”) technology which makes the elements resistant to ultra-violet light, virtually indestructible and highly appealing. A boat motor, a method of attaching a boat stabilizer to a boat motor and a method of molding a boat stabilizer having at least one decorative element integrally embedded in the top surface thereof are also provided.

  • Patent number: 8298496
    Abstract: A fluidic configuration, both structural and methodological, for the injection of sample greatly reduces dead volume allowing rapid transition to 100% sample in a flow cell. For a continuous flow injection analysis system the structure and method provide counter flows to remove in one direction the dispersed region of the sample to waste before injecting non-dispersed sample into the flow cell by reversing the effective flow direction. The injection point itself is directly adjacent to the flow cell where all channels are microfluidic channels. Therefore, only the flow cell volume needs to be displaced during injection of sample in order to achieve 100% transition to sample within the flow cell. This greatly accelerates the rise and fall times thereby extending the kinetic range of the real-time interaction analysis instrument. In addition such rapid transition to sample improves overall data quality thereby improving kinetic model fitting.

  • Patent number: 8243274
    Abstract: A diesel particulate matter (DPM) monitor that can be worn, attached to a particular location or piece of equipment, and collects real-time data about DPM levels. In an exemplary embodiment, ambient air is drawn by a flow-controlled diaphragm pump through a particle size selector which only passes submicron particles. These particles are collected on an optically transparent filter. A laser illuminates the filter and the transmittance of the laser beam is measured in real-time by a photo detector. As DPM accumulates on the filter, the laser transmittance decreases. The instrument is calibrated to convert this decrease in transmittance to a real-time concentration of elemental carbon in the air.

  • Patent number: 8215717
    Abstract: A towable dump trailer is provided. The towable dump trailer comprises a first, second and third frame. The first frame comprises one or more sets of wheels. The second frame is attached to the tow vehicle and can be displaced horizontally relative to the first frame by the towing vehicle moving rearward or forward. The third frame provides a support frame for the trailer bed. The dump trailer is operated by immobilizing the first frame and causing the second frame to move horizontally relative to the first frame. This horizontal displacement causes the third frame to pivot as a result of one or more pivoting arms translating the horizontal movement to pivotal movement. The dump trailer can be configured to provide a dumping action by either forward or rearward horizontal displacement of the second frame relative to the first frame.
