  • Patent number: 10820513
    Abstract: A rephasing system may include a first hydraulic cylinder, a second hydraulic cylinder, a first rephasing valve, a second rephasing valve and a controller. The first hydraulic cylinder and the second hydraulic cylinder include first and second pistons, respectively. A first hydraulic fluid line connects a hydraulic supply to a first side of the first piston while a second hydraulic fluid line connects a second side of the first piston to a first side of the second piston. The first rephasing valve fluidly couples the first side of the first piston to the first side of the second piston while the second hydraulic fluid line fluidly couples the second side of the second piston to the hydraulic supply. The controller selectively opens and closes the first and second rephasing valves to re-phase the first and second pistons.

  • Patent number: 10595462
    Abstract: A harvester head may include a position adjustable reel having a first segment and a second segment, a hydraulic supply comprising a pump and a reservoir, a first plurality of hydraulic cylinders coupled to the first segment to reposition the first segment, a second plurality of hydraulic cylinders coupled to the second segment to reposition the second segment, a first bidirectional valve operably coupled between the hydraulic supply and the first plurality of hydraulic cylinders, a second bidirectional valve operably coupled between the hydraulic supply and the second plurality of hydraulic cylinders, at least one sensor to sense relative positioning of the first segment and the second segment and a controller. The controller may output control signals to the first bidirectional valve and the second bidirectional valve based upon signals from the at least one sensor to synchronize positioning of the first segment and the second segment.

  • Patent number: 10450332
    Abstract: Compounds having hindered amine and oxyalkyl amine light stabilizers can mitigate the adverse effects of actinic radiation, such as visible and ultraviolet light, in particular on substrates such as glass or ceramic substrates. Polymers derived from such compounds. Nanoparticles, substrates, such as glass or ceramic substrates, or both nanoparticles and substrates, having such compounds affixed thereto. Articles containing at least one of such polymers, nanoparticles, substrates, or compounds.

  • Publication number: 20190223379
    Abstract: An overall machine operational state (such as a problem state, field state, machine state, other non-problem state, etc.) is identified, and exit and entry conditions are monitored to determine whether the machine transitions into another operational state. When the machine transitions into a problem state, a multiple input, multiple output control system uses a state machine to identify the problem state and a solution is identified. The solution is indicative of machine settings that will return the machine to an acceptable, operational state. Control signals are generated to modify the machine settings based on the identified solution.

  • Patent number: 4073267
    Abstract: A vapor generator and heat exchanger, particularly suited for use in a substantially cylindrical cavity in a pressure vessel includes high and low temperature sections of the vapor generator positioned coaxially with the annular outer section terminating a distance from the end of the central or axial section to form at the one end an annulus arranged between the central or axial section and the pressure vessel wall. A plurality of reheater or heat exchanger sections and various inlet and outlet conduits are positioned in the annulus. A heating fluid is directed first transversely over the tubes of the reheater sections, then along the tubes of the central or axial high temperature section after passing over the outer annular low temperature section.
