Abstract: In a briquetting press, the delivery end of a compressing cylinder is closed by a swivellable cylinder bottom which can be displaced between a working position which is in alignment with the axis of the compressing cylinder and an unblocking position which unblocks the end of the compressing cylinder.

Abstract: A comminution machine comprises a rotor which is equipped with blade elements and interacts with at least one counter-blade that is mounted stationarily in the housing. The rotor is separated by a sieve from a collection compartment for comminuted material. The rotor has a rotor base having through-openings, in which rotor base a screw is arranged. In this way, the rotor itself can be used as an additional sieve via which sufficiently comminuted material can be discharged.

Abstract: There is described a novel woven-fabric packing 1, in which a plurality of woven-fabric layers 2 of metal or plastic filaments 3 are disposed parallel to one another. The woven-fabric layers 2 have protuberances 4, at least one protuberance 4 having an opening 5, which lies in an opening plane 6, which is oriented at an angle of 40 to 140 degrees relative to the woven-fabric layer 2. The openings 5 of woven-fabric layers 2 are all oriented in one opening direction X.

Abstract: A fabric packing has a plurality of layers made of a filament of metal or plastic and includes bulges for maintaining the fabric layers at a distance. The bulges have first protuberances of generally trough-shaped configuration and second protuberances formed on the first protuberances, thereby defining respective apexes. The second protuberances are sized smaller than the first protuberances, wherein neighboring fabric layers are supported on one another via the second protuberances.

Abstract: 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.

Abstract: A grinder for comminuting waste material comprises a frame structure (18, 20). A grinding rotor (24) is rotatably carried by the frame structure (18, 20.) The grinding rotor (24) carries a plurality of cutting tools (36) cooperating with a counter blade (26, 28) carried by the frame structure (18, 20). Two plate chain conveyors (68, 70) are vertically aligned so that working runs (80, 120) thereof form a converging moving wall funnel positively feeding pieces (146, 148) of material to be comminuted towards a grinding unit (12) formed by the grinding rotor (24) and the counter blade (26, 28).

Abstract: 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.

Abstract: A biologically active compound can be solubilized by reaction in different sequences to form a derivative carrying the active moiety, a linking group such as an optionally substituted diisocyanate radical, a polyether moiety such as a polyoxyethylene radical, and a terminal group such as a butyl radical, e.g. ##STR1## n=1 to 400. The active materials can be agricultural chemicals, pharmaceuticals, and the like.
