Abstract: A method for reducing the strip tension of a rolling stock, may include: transporting the rolling stock using a roller table between two successive rolling units, wherein a rolling stock loop is formed in a depression in a section of the roller table between the two rolling units, the rolling stock loop being supported by the roller table at least in one off-center portion of the section, wherein the supporting line of the roller table in this portion corresponds to the catenary curve of the free span; measuring a loop depth of the rolling stock loop; calculating a desired value of the loop depth that corresponds substantially to the free span, e.g., depending on the material, thickness and temperature of the rolling stock; controlling the main drives and/or the gap adjustment of the rolling units based on the desired value and the measured loop depth, such that the loop depth substantially corresponds to the desired value.

Abstract: A basic materials industry facility having a type 1 electrical consumer with at least three working points that each have a respective expected power consumption is disclosed. The facility can also have type 2 or type 3 consumers, each having only two working points or a single expected power consumption assigned to them, respectively. Schedule diagrams for type 1 and 2 consumers define their working points as a function of time, taking into account technological criteria for the operation of the facility, and are continuously updated using actual energy consumption data in such a way that the expected total energy consumption between starting time point and a predefined end time point does not exceed a maximum permissible total energy consumption. Preferably the consumers are controlled so that the expected total energy consumption is brought close to the maximum permissible energy consumption.

The control device (10) operates the coiling device (1) in such a way that a current strip temperature and/or a current microstructure property of the strip is/are determined by taking measurements or calculating a model, the control device (10) determines a current desired torque value (MH,MR) from the actual value or a variable derived therefrom, and the control device (10) operates the coiler (5) and the optional drive roll (7) by the current desired torque value (MH,MR). The coiling device (1) has the advantage of improving the coiling quality as well as the strip quality in terms of the strip thickness and width.

Abstract: A solenoid valve with pressure limitation for motor vehicle brake systems with slip control. The solenoid valve has a seat valve with the valve seat, valve element and restoring spring, which holds the seat valve in an open position. The valve element is fastened on a valve tappet, which is axially displaceable in a valve housing and is transferred into a seat-valve-closed position by an electromagnet when the electromagnet is supplied with current. In the valve-closed position, there acts a pressure-limiting spring, which fixes the valve-opening pressure of the seat valve. To achieve a structurally simple valve design with the advantage of simple and accurate setting and adjustment and also of simplified forward assembly of the solenoid valve, the valve tappet is subdivided into first and second tappet elements which are coaxial to each other and relatively displaceable, of which the first tappet element bears the valve element and the second tappet element can be driven by the electromagnet.

Abstract: Layers containing silicon and oxygen are formed by means of low pressure chemical vapor deposition. As a source for silicon and oxygen, tetraethylorthosilicate (TEOS) is used which is drawn into the low pressure area of the deposition apparatus in liquid form and evaporated there. If necessary, oxygen is introduced into the low pressure area. The reactants are directed into the reaction zone which has been heated to a predetermined temperature, and reacted there. The reaction product is deposited onto the substrates provided therein. If the deposited layer is to comprise still further elements, liquid substances containing such elements are mixed with the liquid TEOS prior to being drawn into the evaporating area, in a ratio adapted to the desired layer composition. Both with respect to layer thickness and composition the layers deposited are highly homogeneous.

Abstract: Urinary and intestinal tract excrement, such as from a stoma patient, is thickened by admixture with a cross-linked water-swellable polymer, preferably including (meth)acrylic acid, nitrile and/or amide units. A hydrophilic adsorption agent such as silicic acid may also be included along with perfume materials, binders and/or enzyme inhibitors. By thickening, it prevents sloshing of the contents, reduces odors and facilitates ultimate disposal.
