  • Publication number: 20090321317
    Abstract: The invention relates to a method and device for processing plastic-containing and organic fluids based on crude oil, cooking oil, fats or the like, wherein the substance mixture is fed into a reactor, is then melted in the melting zone of the reactor and the interfering substances are discharged from the melt. The long-chained polymers still present in the melt are cracked in a crack zone of the reactor until they assume a gaseous state. Then the gas phase is discharged from the reactor an condensed in a cooler. Impurities are then removed from the volatile liquid present after cooling and the volatile liquid is stored.

  • Patent number: 7628816
    Abstract: Disclosed is a device comprising at least one intervertebral implant (3) and at least one plate (4,5) that is to be connected to the intervertebral implant (3) and an adjacent spine (21-23). The intervertebral implant (3) is connected to at least two spaced-apart plates (4,5). One end of both plates (4,5) respectively forms a fixable joint along with the intervertebral implant (3). Preferably, at least one of the plates (5,4) is embodied in a Z-shaped or L-shaped manner. The inventive device provides for great adaptability to the anatomic characteristics of the spinal column and a modular structure while the number of parts is kept small.

  • Publication number: 20090111164
    Abstract: Disclosed are a method for the anaerobic treatment of pulp-containing waste and a fermentation plant for such products, wherein they are first of all mechanically prepared and comminuted, subsequently diluted to a predetermined dry matter content by the addition of process water or the like, and sanitized and anaerobically fermented in a subsequent method step. The remaining rotted residue is divided into a plastics-rich and a pulp-rich fraction, and these fractions are conditioned in conditioning stages to recyclable materials, or to fuel, or to products adapted to be deposited.

  • Publication number: 20080013678
    Abstract: A device for precisely placing instruments or implants in body organs with the aid of a targeting device (40) interacting with a computer tomograph, characterized in that the targeting device is arranged in the form of a navigation device (30) on a carrier (2) which is diplaceable on a substructure like a carriage which can be fixed in relation to the substructure and in that the navigation unit (30) comprises a retaining element for holding and guiding a targeting instrument, implant or other object. The navigation unit (30) can be displaced and/or rotated on one or several planes in relation to the carrier and the retaining element can be displaced and/or rotated on one or several planes in relation to the navigation unit (30), being reciprocally fixable in the adjusted position thereof.

  • Patent number: 6110727
    Abstract: A process and an apparatus for carrying out the process for the biological treatment of organic wastes. In order to achieve more effective treatment of the material, in a horizontally oriented reactor, a circulating agitator is disposed which causes circulation of the material with simultaneous advance. The material is leached via spray arms, with simultaneous intense aeration of the material to generate an aerobic biological degradation process.

  • Patent number: 5248602
    Abstract: A process and an installation for utilizing organic substances are proposed, in which the substances are correspondingly comminuted and processed by mixing and reaction stages to utilizable compost.The installation essentially comprises a heatable fermenter with a stirrer located therein. In order to obtain an approximately closed process circuit the comminuted substances are supplied as so-called fresh material by a supply shaft to a conveying shaft constructed as a heat exchanger and undergo corresponding heating therein. Through further supply of fresh material the already heated fresh material is supplied to the fermenter and mixed therein by the stirrer accompanied by further heating.The fermented matter formed in the fermenter, on supplying further fresh material, can be admixed in a specific ratio as so-called bacterial inoculum with the fresh material throughout the process circuit.
