  • Continuous log bucking saw system and method
    Patent number: 6923101
    Abstract: A high-throughput, high-end-product-recovery, lineal log bucking device featuring continuous stem travel during the cutting process by using a simple and efficient machinery design for economy of equipment and monies. The apparatus includes: (1) a saw for cutting stem into logs; and (2) apparatus for accelerating the carrier up to the speed of the stem conveyor(s), maintaining the speed during the cut, decelerating the carrier, and then returning the carrier to its starting point.
    Type: Grant

  • Scroll compressor with structure for preventing reverse rotation
    Patent number: 6203300
    Abstract: A scroll compressor includes structure between an eccentric and a slider block that separates the scroll wraps when the orbiting scroll is driven in a reverse direction by entrapped fluid. In the prior art, entrapped fluid sometimes has driven the orbiting scroll in a reverse direction at shutdown, resulting in undesirable noise. The present invention stops movement of the orbiting scroll relative to the fixed scroll during reverse rotation by opening the fluid chambers dissipating that pressure.
