Title: Rotation body dynamics, a mechanism for generating lift and forward thrust for aircraft or water vessels
Inventor: GOERES HANS DIETER WILHELM
IPC: B64C39/00
Filed: 1981-01-26
Abstract: The mechanism of the rotation body dynamics for generating lift and forward thrust for aircraft or water vessels applies to the generation of lift when fitted above a vehicle and to the generation of forward thrust when fitted to the front side of a vehicle, applies to aircraft in the case of utilisation of aerodynamics, to underwater vehicles or vehicles having underwater lifting or propulsion parts in the case of utilisation of hydrodynamics. The common feature is, firstly, the utilisation of the effect of a medium flowing over surfaces, a pressure reduction being produced for the surfaces over which the medium thus flows, said pressure reduction being called suck, and representing a pressure reduction in comparison with the quiescent pressure and in comparison with other surfaces relative to which the medium is not flowing past, either located opposite or when using there the effect of rotation in the same direction or movement at equal speed, of the surfaces, the second common feature is the knowledge that not only short and long surfaces of any type experience suck in accordance with the speed of a medium when said medium flows past, but also surfaces underneath an intrinsically rotating large vortex, and conversely surfaces which rotate in a corresponding manner underneath a standing column of medium. In this case, the supply and dissipation are of second priority, and, in particular, an absolute pressure increase, a relative suction reinforcement, can be achieved by indentation.

Title: Method and device for separating and removing medium, in particular oil, floating on water
Inventor: SCHOBER HANS
IPC: E02B15/10
Filed: 1981-12-09
Abstract: In order to remove a medium floating on water virtually completely from a water surface, for example, of a choppy sea, a device with a funnel effect is used. Here, three funnel-like trap chambers, for example, are arranged about a common axis of rotation of a trap body. In this arrangement, the funnel surfaces in the direction of rotation are designed as segments which work like trap arms. In each case a certain surface section of the water is enclosed by turning the device about its axis of rotation, and the oil thus trapped is concentrated at the upper pump-out end of each trap chamber with a considerably smaller cross-section so that a thick oil cushion develops. This oil cushion can thus easily be pumped out.
