  • Patent number: 4598815
    Abstract: A diverter assembly, for diverting baggage from a main belt conveyor to an intersecting conveyor, includes a single row of diverter rollers pivotally mounted therein. The diverter rollers are continuously rotated with power mechanically derived from the main conveyor. The diverter assembly is mounted in a gap formed in the main conveyor and a lift mechanism raises and lowers the diverter rollers while a swivel mechanism simultaneously pivots the rollers so that the articles are diverted. The lift mechanism and swivel mechanism are synchronized, so that when the rollers are lowered they are oriented coaxially to take up very little horizontal space, and to decrease the size of the gap over which articles pass unsupported. When the diverter rollers are raised, however, the rollers are automatically pivoted, in part taking advantage of the greater room available, and the rollers divert articles from the main conveyor.

    Abstract: This invention comprises a rotatable annular probe-positioner which carries at least one radially disposed sensing probe, such as a Pitot tube having a right-angled tip. The positioner can be coaxially and rotatably mounted within a compressor casing or the like and then actuated to orient the sensing probe as required to make measurements at selected stations in the annulus between the positioner and compressor casing. The positioner can be actuated to (a) selectively move the probe along its own axis, (b) adjust the yaw angle of the right-angled probe tip, and (c) revolve the probe about the axis common to the positioner and casing. A cam plate engages a cam-follower portion of the probe and normally rotates with the positioner. The positioner includes a first-motor-driven ring gear which effects slidable movement of the probe by rotating the positioner at a time when an external pneumatic cylinder is actuated to engage the cam plate and hold it stationary.
