  • Patent number: 6323565
    Abstract: A method and apparatus for operating a power liftgate in an automobile, such as a minivan, is disclosed. The invention is comprised in a control system that includes a user input interface for receiving power liftgate actuation requests from a user. The actuation signals are carried to a body control module (BCM) where the request is broadcast to a power liftgate module (PLGM) over a serial data bus communications network meeting the SAE J1850 multiplex communications protocol standard. Upon receipt of the actuation message, the PLGM monitors several operating conditions of the automobile and makes a determination whether or not to carry out the power liftgate activation request. Power liftgate actuation is controlled by the PLGM via electric motors located at or near the liftgate. The user input interface includes interior switches as well as a RKE system.

  • Patent number: 6314788
    Abstract: A method and apparatus for determining bearing failure in a grinding mill drive shaft. The drive shaft is comprised of an upper shaft section and removable shaft section operatively connected to a gearbox drive shaft section. A grinding assembly is attached to the upper shaft section. The upper shaft section is supported by a support bearing. The respective drive shaft sections are joined together by couplings. A gap of a predetermined distance is left between the upper shaft section and the removable shaft section within the coupling. The gap between the upper and removable shaft sections periodically is measured. A decrease in the gap indicates support bearing wear. In bearing failure, the upper shaft section rests on the removable shaft section and the couplings hold the shaft together with the couplings and the gearbox drive shaft section supporting the weight.

  • Patent number: 6154948
    Abstract: An interchangeable cast metal block for mounting on a rotor shaft, the shaft having a polygonal cross-section. The block includes a substantially circular body having a central bore complementary to the polygonal cross-section of the rotor shaft such that the rotation of the shaft will turn the block. There are at least two opposed cutting blade mounting bosses for attachment of cutting blades on the external surface of the block. The mounting bosses are positioned on the block in a predetermined geometric arrangement relative to a facet of the polygonal center bore such that the block can be reversed and re-mounted on the rotor shaft to effectively double the available number of cutting blade positions. The number of available cutting blade positions is two times the number of facets on the polygonal center bore. A plurality of the blocks may be stacked on the rotor in an array to provide a plurality of cutting blade patterns along the length of the rotor shaft.

    Abstract: A method and apparatus for operating a power sliding door in an automobile, such as a minivan, is disclosed. The invention is comprised in a control system that includes a user input interface for receiving sliding door actuation requests from a user. The actuation signals are carried to a body control module (BCM) where the request is broadcast to a power sliding door module (PSDM) over a serial data bus communications network meeting the SAE J1850 multiplex communications protocol standard. Upon receipt of the actuation message the PSDM monitors several operating conditions of the automobile and makes a determination whether or not to carry out the power sliding door activation request. Power sliding door actuation is controlled by the PSDM via electric motors located at or near the power doors. A power liftgate module (PLGM) controls the power liftgate actuation upon via electric motors located at or near the liftgate. The user input interface includes interior switches as well as a RKE system.

  • Patent number: 5839673
    Abstract: Apparatus for grinding material which enters the grinder in a wet condition and is subject to drying heat at the grinder to leave moisture in the ground material directed for independently material separation so the propelling initially hot gases looses its temperature level before returning to the grinder. A portion of the returning gases carrying ground fine with moisture therein is directed into a bag house to recover the fines and a portion of the drying heat is directed into the bag house to independently maintain a temperature level above the dew point temperature level in the bag house to prevent moisture from plugging the bag house. The apparatus provides two circulation loops, each with its independent moisture control, and a common transport for collecting product from each loop.
