Abstract: The invention relates to a method for using biomass in a biogas process. The aim of the invention is to use substrates having a high nitrogen and solid content, and which using a small amount of water, has very good energy balance and is particularly environmentally friendly. Said aim is achieved by the virtue of the fact that the substrate is treated with a recirculated product in order to form a pumpable medium, and additionally treated with bacteria in cyclones and fermenters, which simultaneously removes the nitrogen in a stripping process, separates the solid fermentation radicals and further uses the recirculated product as a heat-exchanger and reaction medium. Said process is environmentally friendly and has a very good energy balance.

Abstract: The invention provides large surface area geogrids with a high tensile strength, a method and apparatus for producing them, and their use as drain and reinforcement grids and as fences. The method for the continuous production of geogrids which have a large surface area and comprise thermoplastic bars which cross one another and are joined together by welding at the areas where they cross one another is characterized in that single-layer, homogeneous, molecular-oriented plastic bars with a high tensile strength are used and a multiplicity of crossing areas arranged behind one another and next to one another are intermittently welded simultaneously using the vibration-welding technique. In this method, a newly developed vibration-welding apparatus is used, which is characterized in that it has at least one vibration device which can be used to weld at least 100 crossing areas, preferably up to 500 crossing areas, simultaneously.

Abstract: A CT scanner is employed having a first coordinate system called the CT coordinate system related to the CT scanner for determining an actual position of a structure of an object to be examined. A coordinate measuring instrument (MI) is employed which is either a tactile or an optical or multisensor or an ultrasonic coordinate measuring instrument and which has a second coordinate system, the MI coordinate system, related to said coordinate measuring instrument. According to a variant, a) the coordinates of the object are determined in the MI coordinate system, b) the target position of the structure is predefined, c) after steps a) and b) the target position is determined in the MI coordinate system, d) and, the object is positioned in such a way that the target position of the structure comes to lie within a volume detected by the CT scanner using the result of step c).

Abstract: The invention relates to a steam injection module (1), suitable for a unit for the pasteurization or sterilization of liquid to highly viscous food products. A steam tube (2) passes through a product line section (3), transverse to the longitudinal axis, made homogeneously from a single material by cutting with no welded seams. This steam tube (2) exhibits steam outlet openings (7) within the product line section (3). The hot steam at about 150 degrees centigrade is injected into the flowing product through the steam outlet openings. The product line section (3) and this steam cube (2) are each fixed by fixing flanges (8, 8?, 9,9?) in the total line set of the unit.

Abstract: The cover of the container has the hollow (2) with an elliptical outline pointed towards the inside of the container; the hollow has the spherical projection (3), pointed upwards, and the projection has the cylindrical cavity (4) with the opening housing the valve head. The valve head has the form of a circular plate and has an edge with a triangular outline; cooperating with the gasket of the valve. The head valve is installed loosely in the opening by means of the sleeve ending with the flange with distancing projections in the form of radial ribs.

Abstract: The invention relates to oil-flooded screw compressors having a male rotor and female rotor each featuring preferably a ratio of male-to-female rotor lobes of 4:6, 5:6 or 5:7. In order to decrease the bearing load at higher working pressures, the profile sections of the rotors are shortened, and an intermediate plate is appropriately arranged in the free space formed.
