  • Patent number: 6457511
    Abstract: An offset conveyor system utilizes a lower conveying section positioned adjacent a pouring station where molten metal is poured into weighted and jacketed sand molds. Molds are transported on carriers along the lower section from a mold loading station to a weight and jacket placement station to the pouring station. After pouring, the carrier with jacketed mold is moved up an incline to an upper conveying section parallel the lower section and may overlap the lower section partially. Molds are transported in an opposite linear direction relative to the lower section to a weight and jacket removal station and to a mold dump station, where the sand mold and casting are removed from the conveyor. The carrier is returned to the lower conveyor section to receive another mold. The weight and jacket removed from the upper section is placed on a mold on the lower section, therefore only a minimum number of weights and jackets are used.

  • Patent number: 6453210
    Abstract: A predictive industrial control system for controlling individual cells of machines through multiple Programmable Logic Controllers in an investment casting processing and handling operation. An application server located in a remote, non-industrial environment executes an industrial control application (ICA) utilizing tagged reference names corresponding to individual machines and information input devices such as sensors on the production line. The ICA accesses local databases that hold casting shell part numbers and their associated recipe control words, and monitors the system for new shell part numbers as they appear on a load conveyor in the production line. Radio Frequency tags on the part signal the ICA to transfer the appropriate recipe control words and robot moves required to process the part in a primary processing cell's PLC. The PLC then controls each machine in the primary processing cell in accordance with the downloaded commands from the ICA.

  • Patent number: 6449804
    Abstract: A rigid cage cotton gin includes a feeder that delivers seed cotton locks to be ginned. A doffing cylinder at the discharge of the feeder casts seed cotton locks into a bonnet housing, with air inlet vents in the bonnet housing deflecting the seed cotton locks onto a revolving rigid cage having a series of sifting bars that are fixedly mounted thereto. The sifting bars are spaced-apart to define a series of slots. The rigid cage is rotated for seed cotton locks to be drawn to the slots between the sifting bars, and the fibers will be drawn through the slots by air currents flowing through the slots. A fiber-engaging cylinder is mounted within the rigid cage, with the outer surface of the fiber-engaging cylinder abutting the interior surfaces of the sifting bars. The sifting bars are contoured to restrain the cotton seed from moving closer than a predetermined distance from the surface of the fiber-engaging cylinder to control the minimum fiber length removed.
