  • Patent number: 5645307
    Abstract: The invention provides an article carrier for heavy articles such as an outboard motor. It includes a pair of article-encircling loops including a rear strap loop for encircling the stern portion of an outboard motor and a front strap loop encircling the front portion of the motor. Each of the loops is positioned during use in an inclined plane such that the rear strap loop projects rearwardly from the handle at an oblique angle and the front strap loop projects forwardly at an oblique angle whereby the loops lie in inclined planes and encircle the motor obliquely when in place on the motor housing. A handle formed from a flexible member is connected to the article carrier at the top of the motor during use to provide a hand grip for the carrier. Releasable fasteners are secured to at least one of the loops for holding the loops in place on the motor during use.

  • Patent number: 5574232
    Abstract: A flow-through sample cell operable in conjunction with a reflectance or fluorescence spectroscopy apparatus to permit real-time analysis of a liquid sample stream is disclosed. The flow-through sample cell includes a housing and a conical-shaped flow control body positioned within the hollow interior of the housing. A liquid sample stream to be analyzed is introduced into the housing along a flow path tangential to the outer surface of the flow control body so as to cause the liquid sample stream to flow through centrifugal action radially along the outer surface of the conical-shaped flow control body and into a viewing area at the bottom of the sample cell. As the liquid sample stream flows through the viewing area, a real-time analysis of the liquid sample stream may be made by an analyzer device positioned outside the sample cell and adjacent to the viewing area.
