Inventor: KOENIG KLAUS DIPL ING
IPC: A61N5/06
Filed: 1993-02-27
Abstract: The invention relates to a tanning apparatus which comprises a couch, an illuminator and, where appropriate, a face tanning apparatus which form a tanning tunnel, UV radiation being transmitted from the interior of the couch, of the illuminator and, where appropriate, of the face tanning apparatus, into the tanning tunnel. This tanning device is to be improved in such a way that there is hardly any waste heat on the body, it does not necessitate cooling of the apparatus and manages with a reduced connected load. This is achieved in that there is a central radiation generator which is arranged remote from the radiation emergence surfaces delimiting the tanning tunnel, and in that the central radiation generator is connected to the interior of the couch, of the illuminator and, where appropriate, of the face tanning apparatus via fibre optical waveguides which project from the wall sections of the couch, the illuminator and, where appropriate, the face tanning apparatus, opposite the radiation emergence surfaces, each end of the fibre optical waveguides being allocated to a device which causes the emerging bundle of rays to be distributed over a large surface area with uniform distribution of the radiation.   <IMAGE>

Title: Method and device for generating energetically useful vorticity from parallel flows
Inventor: SCHATZ JUERGEN
IPC: F03D3/04
Filed: 1993-03-22
Abstract: A method and a device for generating useful vorticity from parallel flows is proposed which has a flow module for producing a potential vortex and a turbine which is arranged in the direction of action of the potential vortex. The flow module comprises an outer hollow body constructed from a plurality of diffusor columns, on or between which flaps are arranged. The outer hollow body is covered with plates which have one or more outflow openings. The turbine is arranged in the region of one or more outflow openings in such a way that approximately half the width of the rotor body is covered by the plates. The dynamic (stagnation, head) pressure acting on the outer hollow body generates a rotary flow. Dynamic pressures and circulations are produced on the diffusor column. The rotary flow generated inside drives by means of slotted-type injectors jet flows which because of the shape of the diffusor columns and of the flaps are subject to torques and generate a rotary flow around the flow module. Because of the higher wall shears of the jet flows and the resulting outer rotary flow, more vorticity is generated which is diffused into the inward-going rotary flow and accumulates to form a strong vortex. The vertical axis rotor is driven asynchronously in the vortex core. The air incident on the circular tracks above the radius of the rotor body flows into the rotor body, is imparted an angular momentum and is ... in a manner concentrating speed as ...
