Abstract: In a collection container for bulk material with a conveying pump (204) or a suction tube arranged off center, with a container wall (202), and a substantially level container bottom, at least one removing arm (210) is adapted for movement in the vicinity of the container bottom. The removing arm (210) is arranged on a traction means and guided in the region of the container wall (202).

Abstract: A metering drum assembly for the rotation of can-shaped objects over a surface from a first to second location. The drum device employs an inner, hollow, non-rotating, cylindrical member and an outer, hollow, rotating, cylindrical member, each cylindrical member being oriented about the same longitudinal axis. A vacuum is drawn within the inner, hollow, non-rotating, cylindrical member pulling air through the perforated surface of the outer, hollow, rotating, cylindrical member only across a defined segment of orientation.

Abstract: A method for extinguishing fires which is particularly suited for extinguishing burning liquids. The area of the fire is covered by granulated or chopped mineral wool which is spread out over the fire in a sufficiently thick layer. The apparatus for carrying out the method consists of a blower which is provided with knives by means of which the mineral wool may be granulated. The apparatus can be used for removing the mineral wool after the fire has been extinguished.

Abstract: Trash removal apparatus in a sugar cane harvester comprises an axial flow extractor fan having multiple blades to draw trash out of harvested cane and to discharge it through a duct on the pressure side of the fan. The duct is in the form of a helical trash guide member which collects the trash out of the air flow and discharges the trash laterally. The diameter of the fan blades is chosen so as to leave a relatively large annular gap between their ends and the wall of the duct through which most of the trash passes thereby reducing power consumption by the fan.
