  • 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.

  • Patent number: 5557825
    Abstract: A door retainer mechanism on a padmounted switchgear cabinet includes a pair of elongated links coupled between an access door and housing of the cabinet. The links are pivotally connected respectively to the access door and housing and also pivotally connected to one another. The links are pivotable relative to each other between folded and unfolded conditions with respect to one another as the access door is moved between closed and opened positions relative to the cabinet housing. The links are operable automatically to latch with one another in the unfolded condition upon the access door reaching the opened position after being moved by a worker from the closed position relative to the cabinet housing. The links of the door retainer mechanism, once they have reached the unfolded condition and become latched with one another, function to retain the access door in the opened position and prevent the access door from returning to the closed position.
