  • Patent number: 5505389
    Abstract: A recirculating grinding plant with a crushing high-pressure roller press and sifter which has low energy consumption and which operates without a separate drive disagglomerator for disagglomerating the roll press scabs. The raw material together with the scabs of the roller press are delivered directly to the delivery chute (15) of the disagglomerator/sifter, which is a static cascade sifter (16) enclosed by a column-like sifter housing and having two sift-zone barriers. The barriers form a sifting zone therebetween and sifter air flows through them in a cross-current fashion. The barriers include cascade-like or shutter-like deflectors (16a, 16b) pointing towards the bottom in direction of the discharge opening (19) for the sifted coarse material fragments (20). The two deflectors (16a, 16b) and the sifting zone (17) located therebetween are arranged oblique to the vertical.

  • Patent number: 5502342
    Abstract: In the fastening of noise-generating machines, particularly centrifuges, the noise in the form of structure-borne noise is often transmitted to other parts of the plant. In order to largely to prevent this, separating joints (16, 17) filled with structure-borne noise deadening material are placed between the fastening parts (14, 15) and the section beams (11, 11') to which the centrifuge with its housing is fastened.

  • Patent number: 5449422
    Abstract: In the heat treatment of heat treatable material in an industrial furnace, in particular for the annealing of annealable material such as, for example, aluminum strip wound into a coil (1), by means of blowing of the annealable material with hot gas jets (8) issuing from nozzles (7), in order to insure a very good and uniform heat transfer from the hot gas stream to the material and a completely uniform temperature distribution in the coil (1), and also the rapid heating thereof, without any need to fear locally partial overtemperatures in the coil, it is proposed in accordance with the invention to move the annealable material such as, for example, the coil (1), and the hot gas jets (8) relative to one another, for example by means of the fact that the coil (1) and/or the hot gas nozzles (7) are rotated about the coil axis, so that the blowing impingement points of the hot gas jets (8) move on the blown surface of the annealable material and all desired portions there can be swept in controlled fashion.

  • Patent number: 5428945
    Abstract: The cleaning device for a harvester thresher includes a cross-flow fan supplying air to the cleaning sieve section and air guiding structure in the discharge flow from the fan to effect desired air distribution.

  • Patent number: 5419298
    Abstract: A fuel injection pump element 15 is mounted in an engine crankcase (1) adjacent its associated cylinder 9, and in substantially parallel orientation thereto so that the high pressure outlet 20 of the injection pump element 15 is close to the injection valve 13 thus permitting a very short injection line 21. Mounting the fuel injection pump element 15 within the crankcase provides a very rigid mechanical support therefor. Use of a very short fuel injection line provides superior hydraulic rigidity as is required for achieving high injection pressures. A special bushing 31 with fuel passage may be used to mount the pump plunger bushing 19. The special bushing 31 may be made of high quality material of low porosity to add strength and avoid fuel leakage that may otherwise occur because of the porosity of the case iron crankcase.
