Abstract: A materials processing system adapted for the reduction of metallic materials including a material feed portion configured to convey materials to a mill portion comprising a motor driven rotor in close running fit with a cage mounted grate through which reduced material is discharged onto a conveyer. The cage is biased to a closed operating position by one or more hydraulic rams. A control system receives signals from a speed sensor operatively coupled to the rotor, and is configured to regulate the hydraulic rams, thereby controlling the opening and closing of the cage in response to rotation of the rotor. The control system is further configured to regulate the operation of the materials feed portion to suspend material feed during opening of the cage, permitting trapped or jammed material to be expelled from the mill portion.

Abstract: A roll crusher having a box-like main frame, a material inlet and material outlet, a first rotatable crushing roll on the frame and a second rotatable crushing roll mounted on a roll carriage in an opposed, spaced apart relationship to the first crushing roll defining a material crushing gap. The roll carriage is a generally rectangular frame positioned atop the main frame having one end attached to the main frame near the midpoint of the main frame by pivot. The pivot is asymmetrically positioned relative to the axes of the crushing rolls. An actuator between the main frame and the free end of the roll carriage moves the roll carriage about the pivot to adjust the gap between the first and second rolls. The jack can be equipped with a servo motor responsive to a computer program.

Abstract: A method is provided for controlling a power sliding door system having a power drive mechanism for propelling the sliding door and a power latching mechanism for latching the sliding door in a latched condition. The methodology provides enhanced monitoring and control of the power sliding door system to improve the operation of the sliding door in both the power-assisted and manual modes. The control methodology inhibits the operation of the power sliding door system in response to the actuation of any of the sliding door handles or if a fuel door is in the path of the sliding door. The control methodology also inhibits the operation of the sliding door system if a child guard mechanism is enabled. The control methodology includes an obstacle detection routine which detects obstacles in two directions of travel. The control methodology does not require the power drive mechanism or inertia to cause the latch mechanism to latch the sliding door in the latched condition.

Abstract: A closed loop control system for monitoring and regulating operation of a grinding mill to reduce material in quantity to exactly match a processor material demand. The control system regulates the operation of components of a grinding mill at in response to a linear interpolation of variables between predetermined set points stored in register tables, so as to substantially match the mill reducing capability with variations in the percentage of the processor material demand, without the need for operator intervention. Multiple register tables are provided to accommodate different feed materials or blends, and an operational history record is maintained to allow for reconstruction of events leading to any component failures.

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.

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.

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.

Abstract: Apparatus for and method of reducing spherically shaped fluid coke waste by-product pellets into a pulverized condition for use as a fuel in which there is a first grinding and pulverizing mill initially receiving the waste material which, because of its spherical shape is difficult to pulverize, and accordingly the waste material is transported to a second grinding mill where its spherical shape is altered to render it more easily pulverizable upon return to the first grinding mill where the final pulverizing of the waste material takes place prior to discharge to a point of use which may be to directly fire a furnace, a boiler or a kiln. The waste material is usually rather wet and requires drying so as not to choke the grinding apparatus, and for this purpose heat generated during the burning of the pulverized waste material is returned to the apparatus for the purpose of drying the waste material during its processing in the respective mills.
