    摘要： A bucket wheel excavator has a scraper blade mounted on the bogie and whose height is independent of the raising and lowering of the bucket wheel to maintain a level track for the crawler bogie. The scraper blade can be tilted about a horizontal axis by at least one hydraulic cylinder.

    摘要： A bucket-wheel excavator has its bucket-wheel conveyor stopped when a truck is fully loaded so that a new truck can be brought into position, the continuously-operating bucket wheel filling the bucket-wheel chute with a first store of the material. After an empty pass of the dumping conveyor, the bucket-wheel conveyor is driven at a creeping speed and a second store of the material is formed in the receiving chute of the dumping conveyor which is turned onto operate at creeping speed when the material reaches the upper belt drum of the bucket-wheel conveyor belt. Once the empty truck is in position, the belts are accelerated to maximum speed.

    摘要： Cyclohexane-1,3-dione derivatives of the formula ##STR1## where A is phenyl which is monosubstituted in the ortho- or meta-position by alkoxy, nitro, halogen or methylsulfonyl, or is phenyl which is monosubstituted in the ortho-, meta- or para-position by alkyl, phenyl, alkoxy, fluorine-substituted alkoxy, unsubstituted or substituted phenoxy, alkenyloxy, alkynyloxy, unsubstituted or substituted benzyloxy, alkylsulfinyl, alkylsulfonyl, alkylsulfonyloxy, trifluoromethyl, alkoxyalkyl or alkoxyalkoxy, or is phenyl which is disubstituted trisubstituted or tetrasubstituted by identical or different substituents selected from the group consisting of alkyl, alkoxy, halogen, nitro and 2,4-dichlorophenoxy, with the proviso that, where the substituents are identical, the disubstituted, trisubstituted or tetrasubstituted phenyl radical does not carry methyl radicals, R.sup.1 is hydrogen, methoxycarbonyl, ethoxycarbonyl, methyl or cyano, R.sup.2 is alkyl, and R.sup.3 is alkyl, alkenyl, haloalkenyl or propargyl, or salts of these compounds, and their use for combatting unwanted plant growth.
