Patent number: 9334172Abstract: In a method for recovering volatile components from a solid material, a liquid phase is mechanically removed from the solid material. Subsequently, the solid material is dried by exposing the solid material to superheated steam circulating in a closed circuit. From the closed circuit excess steam that contains volatile components given off by the solid material is removed. The volatile components are separated from the excess steam by condensing the excess steam to a condensed phase and the volatile components are from the condensed phase by adding suitable ions to the condensed phase to crystallize the volatile components.Type: GrantFiled: May 4, 2015Date of Patent: May 10, 2016Assignees: Fraunhofer-Gesellschaft zur Föderung der angewandten Forschung e.

Publication number: 20160069026Abstract: In a method for impregnating semi-finished fibrous products using resin as the impregnating means, winding or laying the semi-finished fibrous products in a plurality of layers on top of one another onto a receiving carrier is initially performed. Here, lower layers lie close to the receiving carrier, and upper layers lie more remote therefrom. The receiving carrier is configured so as to be permeable to the impregnating means. The impregnating means is then introduced through the receiving carrier into the semi-finished fibrous products, wherein the impregnating means initially permeates the lower layers and then permeates the upper layers of the semi-finished fibrous products.Type: ApplicationFiled: March 21, 2014Publication date: March 10, 2016Applicant: Universität StuttgartInventors: Gerd FALK, Markus BLANDL

Patent number: 7735782Abstract: A flow surface (16), e.g. on a swept aircraft wing, has a three-dimensional boundary-layer flow. The surface is defined by a spanwise direction (z) and a chordwise direction (x). In or on the flow surface excitation locations (22) are arranged, exciting primary disturbances. The disclosure is characterized in that the excitation locations (22) are arranged such that benign steady primary disturbances are excited and maintained on a sufficiently-high amplitude level as longitudinal vortices respectively crossflow vortices, suppressing naturally growing nocent primary disturbances by a non-linear physical mechanism. The benign primary disturbances preserve a laminar flow, such that unsteady secondary disturbances, which may initiate turbulence and which, otherwise, are excited in streamwise direction by nocent primary vortices, are suppressed or at least stabilized.Type: GrantFiled: August 1, 2006Date of Patent: June 15, 2010Assignee: Universitat StuttgartInventors: Markus Kloker, Ralf Messing

Patent number: 7551036Abstract: An H.F. power amplifier is disclosed having a plurality of branches (10, 11, 12) switched in parallel. Each branch comprises a plurality of amplifier elements (T1, T4) switched in series. Resistors (R2, R5) enable the voltage (U_DS) applied to the amplifier elements (T1, T4) to be set at a fraction of a supply voltage (Ud) applied to the branches (10, 11, 12). Capacitors (C2, C4) are used to adjust the source impedance of the amplifier elements (T2, T4). In order to prevent the gate-drain voltage (U_GD) from exceeding the breakdown voltage of an amplifier element (T1, T4) and damaging the amplifier element (T1, T4), a limiting path (7) is connected according to the invention between the gate terminal (G) and the drain terminal (D) of the amplifier element (T1, T4), the limiting path (7) being switchable between a conducting state and a blocking state depending on the gate-drain voltage (U_GD).Type: GrantFiled: November 10, 2005Date of Patent: June 23, 2009Assignee: Universitat StuttgartInventors: Manfred Berroth, Lei Wu
