  • Patent number: 5487228
    Abstract: In a material transfer system, material from an excavation is drawn into a vessel by suction from a vacuum source. The vessel has discharge flaps at the bottom that are held closed by the suction. When the weight of the material in the vessel reaches a predetermined value, the flaps open and the material is discharged from the vessel. After the discharge, counterweights almost close the flaps and the suction seals the discharge flaps so that additional material is drawn into the vessel. The vessel includes a vibratory section and has sides that slope outwardly from top to bottom. The material entering the vessel contacts the vibratory section at a predetermined angle and is redirected to the discharge flaps without any caking on the vessel walls. The opening through the discharge flaps is larger than the inlet through which the material enters the vessel so that objects entering the vessel are discharged.

  • Patent number: 5484336
    Abstract: A lubricant tank structure for a cotton harvester wherein the tank is located at the rear of a harvester behind the engine and near the fuel and water tanks. The tank shares support with an adjacent tank and is shaped to optimize use of available space. A bladder is installed inside the tank with an opening exiting below the fluid level of the lubricant. The opening is connected to a relatively small diameter sight tube located externally of the tank. The bladder is filled to the bottom level of the gauge with a indicating liquid having a lower viscosity than the grease which is to be gauged and a specific gravity which is approximately the same as the high viscosity grease. When the lubricant tank is filled, the tank contents displaces the indicating liquid which rises in the sight tube until the height of the liquid is approximately the same as the height of the grease so pressures in the system are equalized.

  • Patent number: 5312299
    Abstract: A grain flow measuring device having a sensor plate, on which a piezo-crystal oscillation sensor is disposed behind an impact surface, behind which an oscillation-damping foam material body is maintained by means of doubly folded-over edges of the sensor plate located at its edges. A retainer plate is seated and an amplifier and evaluation circuit with a readable counter is disposed in the foam material body. Grain flow measuring devices of this type are disposed in a harvester below a rocker tray near its output side, because of which grain losses and false measurements are avoided. Damping of the impact surface by means of the foam material body results is such oscillation damping that the determination of the grain mass results from the detected number of oscillations.
