  • Publication number: 20190331462
    Abstract: An armor system for protecting vehicles and other equipment against projectiles and similar threats. A track is mounted on the equipment, and an upper sled and lower sled are moveably attached to the track. An armor panel is pivotally attached to one sled and is pivotally attached with arms to the other sled. The two sleds are independently actuated along the track, such that their relative positions determine both the translational and rotational position of the armor panel. The armor panel can be quickly rotated from an undeployed position against the vehicle through a desired arc outward from the vehicle, which increases the edge-on or nearly edge-on presentation of the armor panel to the projectile.

  • Patent number: 9885299
    Abstract: A method for fuel regulation during a non-motoring operating mode of an internal combustion engine is provided. A fuel regulator employs a first fuel to regulate pressure of a second fuel. The first fuel is communicated to the fuel regulator through a first fuel circuit. The method comprises actuating a fuel injector that introduces the first fuel and the second fuel into a combustion chamber of the internal combustion engine during the non-motoring operating mode. The fuel injector is actuated with an injection command signal having a pulse width below a predetermined maximum value whereby no fuel is injected into the combustion chamber and the first fuel drains from the first fuel circuit through the fuel injector to a supply tank.

  • Publication number: 20180009700
    Abstract: A method of modifying glass frit involves treating the frit with a grain-boundary-healing compound. The method increases transmission and clarity, and reduces haze of a fired enamel coating made from such modified glass frit as compared to a coating not made from such modified glass frit. The grain-boundary-healing compound influences the chemistry at the grain boundaries to prevent haze. The compound burns out to yield a fluxing material that dissolves alkaline carbonates or bicarbonates on the surface of the glass frit. The dissolved species are incorporated into the enamel coating, thereby promoting the fusion of the glass frit and reducing the amount of haze in the enamel coating. The additives also function to prevent the formation of seed crystals on the surface of the glass frit that may inhibit the fusion of the glass frit.

  • Patent number: 9850827
    Abstract: Emission targets, such as NOx levels, for gaseous fuelled internal combustion engines that burn a gaseous fuel in a diffusion combustion mode are increasingly more challenging to achieve. A method of fuel injection for an internal combustion engine fuelled with a gaseous fuel comprises introducing a first amount of pilot fuel in a first stage of fuel injection; introducing a first amount of main fuel (the gaseous fuel) in a second stage of fuel injection; and introducing a second amount of main fuel in a third stage of fuel injection. The first and second amounts of main fuel contribute to load and speed demand of the internal combustion engine. Engine maps calibrated for different engine performance can be employed in different regions of the load and speed range of the engine. The engine maps are blended when the engine transitions between two regions; and momentary excursions into different regions do not change the engine calibration.

  • Publication number: 20170273247
    Abstract: Monitoring current draw of an actuator associated with a rotating arm on a round baler during a net wrapping cycle is used to determine the position of the rotating arm and actuator, as well as to determine the net tension. The current draw of the actuator may be correlated with the home and insert positions of the rotating arm during the net wrapping cycle; thus by monitoring the current draw, the rotating arm and actuator position is determined and may be provided to aid an operator. The net tension during the net wrapping cycle is a function of the rotating arm and actuator current. A calculation of net tension is determined and provided to an operator, allowing the operator to verify performance issues related to the net tension.

  • Publication number: 20170175657
    Abstract: Starting a gaseous fuelled engine employing a pilot fuel at cold temperatures is challenging due to reduced ignitability and combustion efficiency of the fuel(s), and the increased viscosity of engine oil. A technique for starting a compression ignition, gaseous fuelled internal combustion engine employing a pilot fuel comprises determining one of a normal start condition and a cold start condition; during the normal start condition, introducing the pilot fuel into a combustion chamber of the internal combustion engine when the pilot fuel pressure rises above a first pressure; during the cold start condition, introducing the pilot fuel into the combustion chamber when the pilot fuel pressure rises above a second pressure that is higher than the first pressure; and selectively introducing the gaseous fuel into the combustion chamber.

  • Patent number: 9671529
    Abstract: The present subject matter provides a transitional layer and related methods, used to increase the transmission or reflection of light between two mediums having different indices of refraction. The transitional layer is disposed between the two mediums and the transmission or reflection of light is increased by the interaction of light with the transitional layer. The transitional layer has light scattering particles dispersed therein, a single-layer gradient index-of-refraction, a multi-layer gradient index-of-refraction, alternating layers of high and low index-of-refraction, or a combination thereof, in order to increase the transmission or reflectance of light between the two mediums.

  • Patent number: 9622417
    Abstract: The disclosure relates to a system for maintaining proper tension in the one or more fluidly movable belts during the tailgate closing process of a baling cycle. Sensors are used to obtain position data of the bale density system and tailgate system. This information is used by a controller, which then calculates if an adjustment to the speed of the tailgate is necessary to maintain proper tension in the movable belts.

  • Patent number: 9078399
    Abstract: An improved belt guide system has individual guide sleeves mounted on one or more of the guide rolls, one sleeve for each belt, in an agricultural round baler. Each sleeve encircles the roll surface of the guide roll and is positioned between the belt and the guide roll surface in a manner allowing relative rotational movement between the sleeve and the guide roll. Each guide sleeve is thus allowed to match the peripheral speed of the respective belt as it passes over the guide roll and allow slippage to occur between the guide roll surface and the inner circumference of the guide sleeve. Flanges extending radially outwardly on each sleeve end maintain the sleeve alignment with the respective belt.
