摘要:
A comminution machine for waste includes a rotor that carries blade elements and cooperates with counter-blades, which are fixed to the housing. The rotor is driven by a synchronous motor that is excited by a controllable frequency converter. In order to keep the connected power of the comminution machine small and nevertheless be able to apply a large torque to the rotor, the synchronous motor acts upon the rotor via a reduction gearing and a clutch.
摘要:
A pulverizing mill designed especially for waste products made of plastic is equipped with a pulverizing cylinder (14) situated under a downward slanted cover plate (22) by means of which the connection between the pulverizing cylinder (14) and a hopper (52) containing the material to be pulverized can be alteratively opened and closed. When the pulverizing mill is switched off, a control unit (70) continues to energize a cylinder drive (68) until the cover plate has been moved into its closed position. This ensures that the pulverizing cylinder (14) can be restarted, even though the cylinder drive (68) is set to run the pulverizing cylinder at high speeds of preferably 200 to 1000 rpm, as is advantageous for plastic waste products.

2-Carboxymethyl-3-carboxy-chromones and esters of the formula ##STR1## in which R, R.sup.1 and R.sup.2 each independently is hydrogen, an optionally substituted alkyl, alkenyl, cycloalkyl, cycloalkenyl, aralkyl or aryl group, halogen, hydroxyl, cyano or an optionally substituted alkoxy, aryloxy, aralkoxy, alkoxy-carbonyl or dialkylamino group, orR and R.sup.1, together with two carbon atoms of the benzene ring system, form a carbocyclic or heterocyclic 5-membered or 6-membered ring, andR.sup.3 is hydrogen, optionally substituted alkyl, alkenyl, cycloalkyl, cycloalkenyl or aralkyl,are characterized by fungicidal and arthropodicidal activities. The novel compounds are produced by reacting an o-hydroxyacetophenone of the formula ##STR2## with a glyoxylic acid derivative of the formulaOCH--COOZin whichZ is a cation,in the presence of a basic compound, followed by acidification to form the dicarboxylic acid and, optionally, the ester.
