  • Publication number: 20250116092
    Abstract: A control system for a work machine includes an engine, a torque converter, and a lock-up clutch assembly. The lock-up clutch assembly includes a lock-up clutch that can be positioned in an engaged state, for bypassing the torque converter, or a disengaged state. The control system includes a controller configured to determine that the engine is in a cranking state, and cause, based on determining that the engine is in the cranking state, the lock-up clutch to be positioned in the engaged state. The controller is also configured to determine that the lock-up clutch is in the engaged state. The controller is further configured to determine, based on an engine speed, that the engine has started, and cause, based on determining that the engine has started, the lock-up clutch to be positioned in the disengaged state.

  • Patent number: 12257536
    Abstract: A filter element comprises one or more several tubular filter media element segments, which may be pleated filter media ring segments. One or more heat activated disks are used to connect each tubular filter media element segments together and/or to connect tubular filter media element segments with one or more end cap supports. The heat activated disks are solid in form for assembly with tubular filter media ring segment and then heat activated to bond with tubular filter media ring segments. Multiple end caps can be simultaneously bonded to one or more tubular filter media element segments if a filter stack assembly of component are heated together, such as in an oven. Filter media may also be simultaneously cured. Heat activated disks may be used as pleat stabilizers and/or for and/or as part of end caps.

  • Publication number: 20240173674
    Abstract: A separation and/or humidification element that employs fibrous hollow membrane tubes is provided, which may be used for water vapor transfer between different gas streams in a fuel cell application, such as to humidify the reaction gas. At least one and typically two composite end caps encapsulate ends of a bundle of the fibrous hollow membrane tubes. Each composite end cap comprises adhesive (e.g. epoxy) and a preform such as a plastic annular shroud.
