Abstract: A thermodynamic installation with a closed circuit for a working medium employing a compressor and an expansion machine connected thereto; or by a transmission linked by a first heat exchanger and second heat exchanger having the working medium in the heat exchangers and expansion machine continuously in a vapor-liquid phase equilibrium and that complete circulation takes place within the vapor-liquid phase area of the temperature-entropy diagram. The installation can be employed as a heat pump or to provide energy as a turbine resulting in an increased yield.

Abstract: Flywheel set for accumulating energy with elastically supported bearings, resulting in a low critical speed, lying at all times under the operational flywheelspeed.The axial thrust taking bearings, or one bearing, may be operating with magnetic forces.Spherical pivot bearings may be fitted both at the bottom and at the top of the rotor.

Abstract: Centrifuge for the separation of gaseous mixtures with a rotor inside a housing, comprising a hollow, cylindrical or nearly cylindrical rotorpart also called a separating drum, in which drum a gaseous component may condense as a liquid. This liquid is admitted thereafter through openings in the drum to the space between drum and housing. In this space are formed a sequence of narrow openings, so called restrictors in which the liquid is brought to expansion, returning to gas form.These restrictors act also as bearings for the drum. The gaseous component that does not liquefy in the drum is drawn off.

Abstract: Flywheel rotor, particularly suitable for accumulating energy, built up from separate flywheels which are interconnected by means of an elastic link. The link may have the form of a solid of revolution comprising at least a single, relatively thin-walled bellows fold.At least one fold wall of the bellows fold may have the form of a truncated cone. The rotor may comprise cylindrical rotor parts as well as unperforated disks of Laval-shape.

Abstract: Electric solar or windpowerplant with flywheel battery in which the electric generator is in the form of a d.c. generator, electrically connected to brushless d.c. motors switched in parallel which can also act as generators and each of which is coupled to a flywheel.

Abstract: Windmill or solar plant for generating electric energy having a transmission in the form of an epicyclic gear transmission with sun wheel and planet wheels, the sun wheel of which is connected to the generator shaft, and the planet wheels being coupled with a regulator motor having two directions of rotation as well as a variable speed of rotation, the ring gear being driven directly or indirectly by the windmill or driving shaft.
