    摘要： An apparatus for on-line optical monitoring of the quality and/or chemical condition of a fluid; in particular, a hydrocarbon-based fluid used in transportation and industrial applications. The apparatus includes an IR-transparent internal-reflectance-element (IRE) that has at least one essentially flat surface and at least one convex surface, and at least two IR light paths of uniquely determined central-frequency and bandwidth with light from a source entering a flat surface of the IRE, internally reflecting at least once from at least one convex surface of the IRE that can contact a fluid, exiting a flat surface of the IRE, and being received at a detector. The apparatus also includes electronics to power the source and receive output from the detector of each light path. The apparatus can be controlled to independently monitor the IR light reflected within the IRE at the uniquely determined frequency of each path, and to communicate information relevant to the IR light detected.

    摘要： An improved reclining chair including a base frame having spaced arm rests, a back frame pivotally mounted on the arm rest, a seat frame hingedly connected to the back frame at a point below the pivot connection of the back frame to the arm rest and having its front connected by an elongated linkage to the arm rest, the arm rest, elongated link, seat frame and back frame acting as a substantially parallelogram support linkage for the seat, and an elongated fluid spring cylinder having one end pivotally connected to a rigid frame member extending beneath the seat and its other end pivotally connected to the back frame at a point below the hinged seat and back connection and a manually actuated control for locking the spring cylinder at any desired position of the chair between a fully upright and a fully reclined position.
