Abstract: There is disclosed an apparatus for concealing, connecting and organizing power cords and signal cables from multiple devices in an equipment installation comprising a compact enclosure for use on a desktop that has first and second interior side panels facing each other without obstruction across the floor of the enclosure, and a hinged, reinforced, load-bearing top lid. A plurality of AC power outlets is disposed on either or both of the first and second interior side panels and connected in a power circuit via an ON/OFF switch to a power supply cord. The power circuit includes circuits for suppressing interference and transients. The enclosure includes space for containing and plugging in compact power supply blocks and storage space between the first and second interior panels for connecting, organizing and storing excess lengths of the cords and cables.

Abstract: A fiber optic probe (100) provides in-vitro measurement for measuring fluid media containing bubbles and particulate matter where disturbances to fluid dynamics must be kept to a minimum. The probe transmits light to, and receives light from, the measured fluid media across a light-path gap (119) using two, separate fiber support tubes (107A, 107B) to protect the transmitting and receiving fibers and provide a rigid and resilient structure. Each support tube, containing one or more fibers, is bent ninety degrees in a smooth quarter circle to produce a light path gap that is perpendicular to the longitudinal axis (113) of the probe. A cross-member (125) provides precise alignment of the optical axes or the transmitting and receiving fibers. The small-diameter support tubes reduce hydraulic flow disturbances and debris buildup which would occur with conventional probes during tablet dissolution.

Abstract: Self-washing injection apparatus [101] for liquid chromatography injection valves utilizes an interior chamber [105] with a penetrable seal [109] at the top end of the chamber and a needle sleeve seal [113] at the bottom end of the interior chamber. A wash port [145] in the body [103] of the apparatus connects one or more sources of wash fluid to the interior chamber between the penetrable seal and the sleeve seal. The apparatus provides a simple and effective means to aspirate or pump wash fluids from one or more wash fluid reservoirs through the apparatus, the injection port of the injection valve, and associated components.
