Patent number: 12492696Abstract: A landfill pump cycle counter includes a housing defining an internal passage, a poppet disposed within the internal passage, a magnet disposed within an internal cavity of the poppet, a counter, a seat formed on an inner surface of the housing, and a mating surface formed on the poppet. The landfill pump cycle counter is configured to receive liquid output from a landfill pump. The housing extends along an axis and also defines an inlet and an outlet. The internal passage fluidly connects the inlet to the outlet. The poppet is configured to be moved axially between an open state and a closed state. The counter includes a magnetic sensor configured to detect a poppet cycle. The poppet cycle includes the poppet moving from one of the open state and the closed state to the other of the open state and the closed state.Type: GrantFiled: December 15, 2022Date of Patent: December 9, 2025Assignee: Graco Minnesota Inc.Inventors: Daniel O.

Patent number: 8875416Abstract: A laundry treating appliance treats a laundry load according to at least one cycle of operation. A rotatable drum defines a treating chamber and includes an open face through which access is provided to the treating chamber. An air system supplies air to and exhausts air from the treating chamber and includes an airflow portal adjacent the open face and in fluid communication with the treating chamber. A door includes a panel with a flat surface, the door selectively movable to prevent access through the open face, and the flat surface facing the treating chamber when the door closes the open face. A deflector extends away from the flat surface and at least partially overlies the airflow portal when the door closes the open face. The deflector deflects items in the laundry load away from the airflow portal when the door is closed.Type: GrantFiled: April 24, 2012Date of Patent: November 4, 2014Assignee: Whirlpool CorporationInventors: Colin T. Anderson, Michael K. Lindquist, Robert J. Messersmith
