New and valuable diurethanes having a good herbicidal action, herbicides containing these compounds, and a process for controlling the growth of unwanted plants with these compounds.
摘要:
Freshly dredged gravel is washed free of loamy and organic impurities while being continuously conveyed through a wash zone which includes a delivery chute and a plane endless conveyor band entrained in a direction opposite to that of the material delivery. The conveyor band is mounted in a housing which includes side walls closely adjacent the lateral edges of the conveyor band and a hopper below the conveyor band. The conveyor band is trained over a vertically adjustably mounted drive roller and a tensioning roller defining an upper and a lower course of the conveyor band therebetween. Two additional rollers are arranged in vertical alignment and between the first-named rollers, a lower one of these rollers guiding the lower conveyor band course and an upper one of these rollers being vertically adjustably mounted and arranged to depress the upper conveyor band course to form a basin in the wash zone to which the chute delivers the granular material.

摘要:
A device for washing out and classifying organic, clay-like and other impurities from gravel, comprising a charging chute for feeding material into a washing trough. The washing trough comprises a conveyor belt designed to move in a direction perpendicular to the direction of the flow of material and a plurality of shower devices designed to act against the direction of travel of the belt. The conveyor belt is supported by a series of support rollers and tension rollers. These support rollers and tension rollers are supported by a machine frame that can be incline adjusted
