  • Dual concentric robotic high performance automated tape cartridge system
    Publication number: 20030063966
    Abstract: A data storage and retrieval system. In a preferred embodiment, the data storage and retrieval system includes a polygonal array of cells that are inwardly disposed with openings configured to receive data storage units. A first robot unit to transport a data storage unit to and from the polygonal array of cells is located within the polygonal array of cells. A second robot unit is also located within the polygonal array of cells to transport a data storage unit to and from the polygonal array of cells. The second robot unit manipulates the data storage units placed in the cylindrical array of cells independently of the first robot unit.

  • Density insensitive coriolis mass flow rate meter
    Patent number: 4823613
    Abstract: Design criteria for Coriolis mass flow rate meters with flow conduits having two modes of oscillation where the ratio of the resonant frequencies for the two modes is held constant irrespective of changes in the density of the fluid passing through the flow conduits. The design criteria embodied in the requirement that the ratio of modal mass to modal inertia for a flow conduit equal the ratio of the mass of all attachments to the flow conduit divided by the inertia of attachments to the flow conduit.
