Abstract: A peristaltic pump for conveying a fluid guided in a hose includes a hose bed having a counter bearing to accommodate the hose, a support disk rotatable relative to counter bearing, a plurality of squeeze rolls positioned in the peripheral direction on the support disk and a plurality of guide rollers positioned in the peripheral direction on the support disk with a guide groove extending in the peripheral direction on its outer circumference, which forms a first guide plane facing the support disk. In order to be able to provide reliable loading and unloading of different hoses with different properties into the hose bed or from the hose bed, each guide roller has a guide cylinder above the guide groove to guide the hose during loading into the hose bed and/or during unloading from the hose bed.

Abstract: A device for transferring a fluid has a main channel, at least one secondary channel leading at an opening into the main channel, and a flexible closing element for closing the secondary channel. The opening of the secondary channel can be closed in a fluid-tight manner by the flexible closing element, by pressing the closing element with an external force onto or into the opening. In order to prevent that, in the case of a negative pressure in the main channel, the flexible closing element closes the secondary channel even without application of an external force, at least one projection is associated with the or each secondary channel and arranged in the main channel in the area of the opening of the respective secondary channel, and protrudes over the opening or over a lowest level of the opening.

Abstract: A guide vane for a gas turbine with a vane base body which is of single-piece design and comprises a profiled vane blade extending between a vane root and a cover plate and also the vane root formed integrally with the vane blade and the cover plate formed integrally with the vane blade, is intended, in a relatively simple way to be able to be matched to the individual conditions of use with especially little outlay on apparatus and logistics. For this purpose, according to the invention, a flow-routing body with an advance guide blade that is connected upstream of the vane blade as seen in the direction of flow of the working medium of the gas turbine is joined to the vane base body.

Abstract: The invention relates to a guide blade segment of a thermal turbomachine, in particular a gas turbine, comprising a number of profiled blades which are arranged on a platform. A plurality of securing elements for securing the guide blade segment to an associated guide blade support are arranged on the side of the platform which is oriented away from the blade. The aim of the invention is to provide a guide blade segment which can be produced in a simple and economical manner avoiding casting problem areas enabling the guide blade segment to be attached in a particularly reliable and secure manner to the associated guide blade support. According to the invention, at least one section of at least one of the securing elements is a separately produced component which is rigidly connected to the platform or to an additional section of the securing element.

Abstract: A turbine blade for a turbine of a thermal power plant, with a platform for partial delimiting of a flow passage in the turbine, wherein the platform has at least one cooling medium passage, which extends inside the platform, for guiding a cooling medium, is characterized according to the invention in that the at least one cooling medium passage emerges from the platform at at least two connecting openings, and the turbine blade has at least one supplementary component which can be fastened on the platform, with a communicating passage, which is designed for interconnecting the connecting openings in a fluid-guiding manner.

Abstract: A turbine blade with an aerodynamically profiled blade leaf which is produced from two assembled shell elements is provided. The shell elements forming the suction-side and the pressure-side blade leaf wall have been assembled by a high-temperature and high-pressure bonding process. In the region of the blade leaf tip, a cramp is provided which hooks the two blade walls together with one another with a form fit.

Abstract: There is described a vane wheel of a turbine comprising at least one vane, the footing thereof being held on a wheel disk. At least one cooling channel is arranged between the wheel disk and the vane footing. The vane wheel having a plurality of turbulators is embodied on at least one of the walls of the cooling channel, the turbulators being configured in such a way that the turbulence and thus the heat transfer of a cooling fluid flowing through the cooling channel are increased.

Abstract: There is described a turbine blade with an aerodynamically profiled blade leaf which is produced from two assembled shell elements. The shell elements forming the suction-side and the pressure-side blade leaf wall have been assembled by means of a high-temperature high-pressure bonding process and, under certain circumstances, may come apart at the blade tip. In order to prevent this, in the region of the blade leaf tip, a cramp is provided which hooks the two blade walls together with one another with a form fit.

Abstract: The application concerns a method for drying a fibrous material by means of a process gas stream flowing through a pipe, including heating the process gas flowing through the pipe by means of a heater with controllable heating power, and conducting a portion of the process gas stream through a bypass pipe bypassing the heater, wherein the ratio of mass flows of process gas flowing through the heater and through the bypass pipe is adjustable, and is distinguished by the fact that the heating power of the heater is controlled according to the set ratio of mass flows of process gas through the heater and through the bypass pipe. The application further concerns a corresponding drying apparatus.

Abstract: There is provided an apparatus which can simplify, expedite and enhance the segregation of undesirable particles from desirable particles in a multiple-layer flow wherein the desirable and undesirable particles are randomly intermixed with each other. This is accomplished by a stepwise reduction of the thickness of the flow to thus locate all or nearly all undesirable particles at or close to the exposed sides of the resulting relatively thin flow so that the undesirable particles can be readily detected and segregated from the thin flow.
