Abstract: A control system for a grain harvester. The control system monitors the output of a grain sensor and uses the monitored value to actuate one or more relays having different energization levels. As each relay is actuated it completes a circuit, which is used to modify power that is fed into a control mechanism and which is used to control an operational parameter of the harvester. Depending upon the monitored value of the sensor, the control system will modify the power that supplies a control mechanism that is used to control an operational parameter of the harvester, such as the groundspeed. If the output from the sensor is less that a predetermined threshold, the harvester will operate normally. If the output of the sensor is above a first threshold, the control system will modify the supply voltage. If the output of the sensor is greater than a second threshold, the control system will modify the supply voltage accordingly, and so forth.

Abstract: A resealable closure for a bag is described wherein the bag has upper and lower ends and including a front wall member, a back wall member, and opposite side wall members. The lower end of the bag is sealed in conventional fashion. The upper ends of the wall members are folded downwardly adjacent the front wall member to form a flap which extends across the upper end of the bag with the upper flap being permanently sealed, by an adhesive, to the front wall member except for a flap portion adjacent one of the side wall members. The resealable closure is positioned between the flap portion and the front wall of the bag and permits the flap portion to be opened to form a pour opening in the upper comer of the bag. The flap portion may be resealed by the resealable closure. The closure is designed so that the contents of the bag will not come into contact with any sticky or tacky surface as the material is being poured from the bag.

Abstract: In a combined cycle power plant, gas turbine exhaust gas is passed through a heat recovery steam generator (HRSG) wherein it may be reheated upstream from a boiler tube section prior to passing through the boiler tube section in a non-contact heat exchange relation with a feedwater supply to produce steam for driving a steam turbine. A plurality of air-atomized, liquid fuel wall burners are utilized, each in combination with a "vee"-shaped flameholder to heat the gas turbine exhaust gas. Each wall burner may be disposed in a recessed opening in the HRSG duct wall and each wall burner has a nozzle portion which may be directed upstream relative to the exhaust gas flow. Each flameholder is approximately parallel to its respective wall burner nozzle axis having one end fixed to the duct wall, upstream from the nozzle axis, and a free end disposed within the HRSG duct.
