A method for determining a wall shear stress distribution on a surface of a body around which air flows. The method includes determining a heat flow distribution into the surface of the body around which air flows by infrared thermography, obtaining a surface pressure distribution on the surface optically and determining the wall shear stress distribution on the surface of the body by processing from at least the heat flow distribution and the surface pressure distribution. The instant abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.

The present invention relates to a gel composition on alcoholic basis, comprising at least one androgenic steroid and at least one C3-C4 diol as enhancer, as well as the use of a composition comprising at least one androgenic steroid on the scrotum for the treatment and/or prophylaxis of hypogonadism.
摘要:
The invention concerns an engraved surface of a deformation tool which deforms a workpiece with an active medium, wherein the deformation tool has a pressure agent feed for the active medium and an engraved surface according to the desired final contour of the workpiece. Accordingly deformation methods are performed with hydro-deforming as well as of internal high-pressure metal forming of a wall of a workpiece by the engraved surface of the tool by way of the pressure medium. Upon withdrawal of the workpiece the pressure medium can pass to the engraved surface of the tool, during the deformation of the following workpiece no contact between the engraved surface and the workpiece wall occurs due to the pressure agent adhering to the engraved surface, whereby undesired deformations occur on the workpiece. Accordingly to overcome this problem microstructures are provided on the engraved surface, wherein the microstructures are suitable to receive the active medium adhering to in the wall of the workpiece and the engraved surface. Undesired deformations of the workpiece are thereby avoided. Furthermore the engravings can serve as a depot for lubricant and thus to minimize friction.

Process for deforming a piece of thin-walled metal tube, comprising the operations of bending the piece of tube with respect to its original axis, in which process the wall of the piece of tube is firstly provided, at least at the location where the bend is intended to be, with a deformation which extends substantially in the longitudinal direction of the piece of tube, and in which process wall material is moved closer to the neutral plane of bending, and the piece of tube is then bent, after which the ultimate shape of the piece of tube which is to be deformed is imposed by hydroforming.
摘要:
An auxiliary device for an inflatable life raft, wherein the life raft has a flotation body, including at least one support tube and a bottom and further having a roof structure, including an inflatable support and a cover, has at least one bracket positioned exterior to the roof structure and spanning the roof structure. The at least one bracket includes a closed, inflatable hollow body and a pressure medium connector for inflating the closed inflatable hollow body with a pressure medium. Fasteners connected to the at least one bracket are provided for connecting the at least one bracket to the life raft.
摘要:
In a method for activating a life raft, wherein the life raft has an inflatable bottom frame, a bottom connected to the bottom frame, an inflatable roof structure, including inflatable tubes connected to the bottom frame and a cover connected to the roof structure, wherein the bottom frame and the inflatable roof structure have at least one inflating opening for an inflation medium, it is suggested to first inflate the roof structure in order to facilitate flipping the life raft into the correct position of use.
