Abstract: A device for testing the quality of microstructurization of a surface (2) having a known target microstructurization quality, comprising a radiation source (1) for coherent radiation, a first detector (10) and a second detector (4) and a masking system, all of which are set up and arranged with respect to one another so that radiation emitted by the radiation source (1) onto the surface (2) produces a diffraction pattern, wherein the diffraction maximum of order n of the diffraction pattern without the masking system would impinge on the first detector (10), the masking system prevents 80% of the photons that are assigned to the diffraction maximum of order n from impinging on the first detector and the diffraction maximum of order a of the diffraction pattern impinges on the second detector (4), wherein n is selected from the group consisting of 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 and a is selected from the group consisting of 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10 and a?n.

Abstract: The invention relates to a diagnostic method to detect a salmonellae infection and/or salmonellae contamination. Fields of use include medicine, veterinary medicine and various branches of industry. The goal of the invention is to develop a reliable test to identify salmonellae. It is based on the task of designing a method that allows the earliest possible identification and covers all important serovars. The diagnostic method to detect a salmonellae infection/contamination in accordance with the invention is characterised in that the SipC of all known salmonellae serovars excreted by the salmonellae can be identified in excretions of patients/animals, carcasses, eggs and food/animal feed.

Abstract: An arrangement for introducing gas bubbles into a liquid, a device for fastening a perforated aeration membrane to an aerator base plate, and an aerator base plate therefor. The aerator base plate has an undercut groove in at least one rim region thereof, into which a locking body clamping the membrane in the groove fits clampingly. The locking body has a generally circular cross-section. The groove has an at least substantially oval cross-section. The locking body is designed to be generally cylindrical.

Abstract: The invention relates to a roller mill, particularly intended for dressing ores. To reduce the energy demand for comminution and classifying a grinding product, a classifying device is positioned below the grinding area and to it is supplied the comminuted ground material under gravity action, as well as classifying air from an annular chamber in the lower region of the grinding bowl and which has at least one fine material outlet and coarse material outlet.

Abstract: A method and apparatus for comminuting particulate material by interparticle comminution in a bed of particles are disclosed. The apparatus includes a vertical roller mill with a horizontal grinding table rotating about a vertical mill axis. At least one grinding roller presses resiliently against a bed of particulate material on the grinding track and applies a compressive force. The geometry of the mill is such that the roller engages the bed of particulate material with a substantially pure rolling action. This minimizes shear forces applied to the particle bed and minimizes the reduction of fines.

Abstract: A method and apparatus for comminuting particulate material by inter-particle comminution in a bed of particles are disclosed. The apparatus includes a vertical roller mill with a horizontal grinding table rotating about a verticle mill axis. At least one grinding roller presses resiliently against a bed of particulate material on the grinding track and applies a compressive force. The geometry of the mill is such that the roller engages the bed of particulate material with a substantially pure rolling action. This minimises shear forces applied to the particle bed and minimises the reduction of fines.

Abstract: A method and system of cooling hardware, sensing hardware, and supporting code streams that enables a non-redundant liquid cooling system to be used seemlessly in conjunction with an air cooling backup solution. The result offers system speed and reliability benefits of liquid cooling except for the brief occasions when the primary cooling system has failed and air cooling takes over. Until the liquid cooling is repaired, system clocks are automatically slowed to be compatible with the circuit speeds possible at the higher temperatures associated with air cooling. When the liquid cooling is repaired, the system clocks are automatically returned to their normal fast state. Depending on the circuit technology used, a supplied voltage may be varied while being air cooled.
