A central multi-port valve (6) is essential for the function, and controllably connects individual channels (3, 4, 7, 7?, 7?, 8) on the module.

Abstract: A method for setting the sizes of film tubes extruded by blown film plants includes changing the film tube size from an initial size to a final size, and optimizing the location of a frost area during the size change by setting the output of a cooling fan. Physical parameters of the initial and final size of the film tube are stored in a control device. The control device takes these physical parameters into account when generating control signals. The control signals form the basis for the control of the cooling fan output.

Abstract: The invention describes a method for setting the sizes of film tubes (1), which are extruded by blow film plants (15), in which method the film tube size is changed from an initial size of a film tube (1) to a final size of a film tube (1), and in which the location of the frost area (3) is optimized during the size change by setting the output of the cooling fan. Physical parameters of the initial and final size of the film tube (1) are stored in the control device (31). The control device (1) takes these physical parameters into account when generating control signals.

Abstract: The invention relates to a liquid distribution unit (10, 20) for dividing a liquid current into a plurality of partial currents. Said unit comprises at least one liquid inlet (13, 23) for the supplied liquid current, a plurality of liquid outlets (14; 24) for the partial currents, and a plurality of channels (15, 25) connecting the liquid inlets (13, 23) to the liquid outlets (14, 24). Said unit is characterised in that the channels (15, 25) symmetrically and respectively branch off (16, 26) into upstream channels (15a, 15b, 15c, 15d, 15c; 25a, 25b, 25c, 25d, 25c) and each connection leading from the liquid inlet (13; 23 ) to one of the liquid outlets (14; 24) comprises the same channels (15, 25) and the same branches (16, 26). A liquid distribution device for the divided distributiion of at least two different liquids; comprises a plurality of such liquid distribution units (10, 20) placed flatly on top of each other.

Abstract: A distance-measuring device is used for measuring a distance between a vehicle and an obstacle. In so doing, dimensions of additional parts that are to be mounted on the vehicle and that project into a space between a detecting device for the distance measurement and the obstacle are taken into account.

Abstract: A process to purge film extrusion systems with at least one extruder for the purpose of changing batches, wherein the speed is changed periodically in at least that part of the extruder in which the material is changed. By considering the mass flow rate of the film extrusion system, advantageous improvements of the process avoid the situation in which the film tears off. To this end, at least one selected guide extruder is operated at a speed which is increased as compared to the normal operation, and at least one selected downstream extruder is operated at a speed that is decreased as compared to the normal operation. Also included are control and operating units and extrusion systems to carry out the process, which include, among other things, the elements necessary for an automated program run of the purging program and the optical display of the parameters of the same.

Abstract: A withdrawal device for a plastic tubular film is manufactured in a blowing method by an extruder. To prevent the formation of center wrinkles in the withdrawal of plastic tubular film, at least one deflection cylinder and/or angle bar has a differing diameter across its length.

Abstract: The present mixer for construction materials, such as a bituminous sludge, has a trough with an inlet and an outlet and two mixing shafts equipped with blades rotatably supported in the trough in parallel to each other. The blades are uniformly spaced along both shafts and staggered by 90.degree. around each shaft whereby the blades of each shaft follow one another in helical succession. Simultaneously the blades form four in line rows on each shaft. The arrangement of the blades is identical on each shaft except that the helix formed by the blades on one shaft has preferably a pitch direction opposite to that formed by the blades on the other shaft since the shafts rotate in opposite directions but convey in the same direction. The spacing between adjacent blades on both shafts is the same. However, blades located in the same plane extending perpendicularly to the longitudinal axes of the shafts are always spaced by 90.degree.

Abstract: The present spreading apparatus for road construction mixtures, such as bituminous cold mixtures, has at least two V- or U-shaped screeding structures or screeds one leading and the other trailing with respect to the working direction. The leading screed extends tandemly, partially into the angle formed by the trailing screed. The leading screed structure has a worm type conveyor connected parallel to each wall of the V- or U-shaped screed. The worm type conveyor assures the homogenity of the road construction mixture and reduces the inherent pressure of the mixture against the leveling elements. Both the leading and the trailing screed are adjustably inclined away from the working direction. The adjustment of the screed position may be made, for example, by a spindle with a hand wheel.
