The method includes actuating a valve to begin dispensing foam insulation into the cavity, the actuation being performed by a user, the actuation by the user fixing a start time and/or a zero volume of a time and/or volume meter; then, dispensing the foam insulation from the insulation dispenser into the cavity as the time and/or volume meter counts time and/or volume dispensed; then when a predetermined time after the start time elapses or a predetermined volume of the foam insulation beyond the zero volume is dispensed as measured by the time and/or volume meter, actuating the valve to stop dispensing the foam insulation into the cavity.

Abstract: An agricultural harvester has a frame and a spout that is movably mounted relative to the frame. A spout actuator drives movement of the spout relative to the frame. Harvesting functionality engages material from a field and delivers the material through an outlet end of the spout as the agricultural harvester moves through the field in a direction of travel. A turn identifier identifies a location of a turn forward of the agricultural harvester and generates a turn location indicator indicative of the location of the turn. A speed detector detects a speed of the agricultural harvester and generates a speed indicator indicative of the detected speed. A position compensation control system generates spout position compensation information based on the turn location indicator and the speed indicator, and a spout position controller controls the spout actuator based on the spout position compensation information.

Abstract: The over-fill monitoring system monitors the liquid level of a container as its being filled and visually indicates that the fill process should be stopped, thereby reducing the chance of over-filling and overflow spills. The over-fill monitoring system includes a fuel probe, a visual “fill limit” indicator, and an electronic control unit. The control unit is responsive to the fuel probe and activates the “fill limit” indicator during the fueling process when the fuel level within the tank reaches a predetermined “fuel fill” level. The control circuitry of the control unit also includes a “shut-down” timer, which deactivates the indicator light after a set period of time to prevent the control unit from drawing power from the battery.

When an incorrect fueling operation, such as the introduction of gasoline into the fuel tank of the diesel-powered vehicle, is attempted the sensor ring alerts the operator visually and/or audibly before fueling starts, thereby preventing incorrect fueling. In alternative embodiments, sensing of an attempted incorrect fueling operation may require only the sensor ring.

Abstract: A funnel for transferring a flowable ingredient into a receiving container and which indicates the level of the flowable ingredient in the receiving container.
