Title: Twin shaft helical gear rotary compressor - has annular grooves in cover and pockets in teeth to balance axial forces
Inventor: RIEDL ALOIS DIPL ING
IPC: F01C21/00
Filed: 1976-05-04
Abstract: The rotary compressor has a housing in which a rotor (1) with helical teeth meshes with a rotor (2) with helical grooves, and is designed to balance the forces in axial direction due to the helical shape of the teeth. Pockets (4, 10) are provided in the end faces on the suction side to counteract these forces to the extent which is compatible with the effective life of the roller bearings on the suction side. The pockets connect with annular grooves (3, 11) which communicate with annular grooves (21, 6) on the pressure side via bores (5, 13). The balancing pressure thereby obtained lies between the outlet and inlet pressure and is determined either by the geometry of recesses (7, 14) in the end cover on the pressure side, or of the end face gaps and the profile of the pockets.

Title: Design factors for marine propeller - use characteristics including wavelength and amplitude of oscillating volume of water displaced
Inventor: HELLWEG GUENTER DIPL ING
IPC: B63H1/36
Filed: 1976-07-09
Abstract: The design of a ship's propeller is based on the fact that its helical shape is determined by the oscillating vortex of water displaced by it. This has a wavelength which increases regularly. The amplitude of this oscillation, which is a function of the wavelength, gives the same volume of displacement of water per wavelength. The speed of flow of the displaced water remains constant for each arbitrary cross section of th displaced volume.

Title: Hydraulic pressure regulator for automatic gear change - has two way magnetic valve excited in high frequency cycle to build up main working pressure
Inventor: WILL GERHARD DIPL ING
IPC: F16H61/02
Filed: 1977-01-28
Abstract: The hydraulic pressure regulator is designed to adjust the main pressure for the clutch and brake bands to decrease snatching when changing up or down. The primary pump delivers pressure medium to a main pressure regulator and a gear selector slide valve. Fluid is then fed to a pressure reduction valve and a reversing valve and back to the main regulator and the torque convertor. The feed pipe between reduction valve and reversing valve leads to a magnetic valve. The magnetic valve is normally open and allows a fluid flow back to the reservoir. When a gear change takes place, the magnetic valve is opened and closed with a high frequency to build up a main working pressure.
