Title: Compensation of forces using a flowing medium - by using closed circuit consisting of outer and inner helix
Inventor: HUBER KLEMENS DIPL ING
IPC: F03G7/00
Filed: 1973-04-19
Abstract: The circuit consists of an outer helix and a concentric inner helix wound in the same rotational sense and connected such that the axial flows through them are in opposite directions, creating a potential rotational flow on the outside and a rotational flow inside. The outer helix may follow a spherical surface with the inner helix being a co-axial cylindrical helix, the system being subjected to oscillation. The system may be excited to oscillation by periodic variation of the pressure, or the density, or the flow rate of the medium at a frequency which is in anti-phase with the oscillation associated with the force to be compensated. The medium may be a highly ionised plasma whose atomic nuclei are being fused to produce energy.

Title: Manufacture of fine machined surfaces on rotary pistons - made from aluminium alloys with high silicium content
Inventor: PIRY HORST DIPL ING
IPC: B23P15/10
Filed: 1974-02-23
Abstract: The surfaces of the side and middle parts of the rotary piston are pre-machined by milling or by a similar machining process, after which the surface of the piston is anodised. The thickness of the anodised layer is approx. equivalent to the thickness of the silicon crystals which have been broken up by the machining process. Before assembly, the side parts are covered with oil and the piston is run in, during which process the anodising wears off. No silicon crystals are torn out of the surface during this process, but an even wear occurs of the whole of the side surfaces of the piston. After wear of the anodised layer, a smooth surface is obtained in which silicon crystals with flat corners are present.

Title: Warm air ducts for windscreen outside - draws air from engine and with extra motor cooling in summer
Inventor: JANSSEN LUTZ
IPC: B60K11/06
Filed: 1974-06-04
Abstract: Flaps (7) are arranged under the front of the windscreen to direct warm air over the outside of the windscreen in winter. The warm air is collected by a bulkhead in the rear of the engine compartment. A second set of flaps (9) in the bottom rear of the engine compartment is directly connected to the upper flaps, to open when the upper flaps are closed and vice versa. These provide an exit for the warm air in summer. The bottom flaps are linked to additional flaps (15, 16) which increase the cooling air flow over the engine in summer. The upper flaps can be arranged so that some of the warm air spills past the edges of the windscreen to blow over the side windows.

Title: Immersed pump with hemispherical rotor - has curved blades and axial inlet and outlet with converging outlet chamber
IPC: F04D29/22
Filed: 1974-07-04
Abstract: The impeller pump, especially an immersed pump is used for filling bulk liquids into smaller containers. A pump of this type can be used also for sewage pumping.
