  • Patent number: 11448238
    Abstract: Various embodiments concern a pneumatic landfill pump cycle counter comprising a spring located within a housing passage and a shuttle comprising a shuttle magnet, the shuttle located within the passage. The shuttle can be configured to move axially by the spring within the passage in an upstream direction to a home position, move axially by one or both of air pressure differential and airflow within the passage in a downstream direction away from the home position to a hold position. The cycle counter can further comprise a counter comprising an element responsive to a magnetic field of the shuttle magnet, the counter configured to increment a numeric count for each complete cycle of the shuttle moving from the home position to the hold position and then back to the home position.
    Type: Grant

  • Patent number: 8387775
    Abstract: A transfer system for providing faster and increased volume processing of eggs having an overhead positioned egg conveyor. A rotating brush wheel positioned underneath the conveyor receives eggs and includes a first and second pluralities of bristles having, respectively, lesser and greater stiffness. An egg receiving reservoir exhibits a receiving lane positioned underneath and in alignment with the brush wheel for receiving and redirecting the eggs in a lane dedicated fashion to a subsequent egg handling operation. A plurality of spool bars are arranged in parallel extending and spaced apart fashion and defining a number of individual egg conveying lanes and each further include first and second spool bar portions secured in end-to-end fashion to establish an overall dimension.
