21	Rotor with a split rotor blade	US10030564	2002-04-12	US06736600B1	2004-05-18	Rudolf Bannasch
A rotor through which a fluid flows in a main direction of flow, provided with at least one rotor blade, the rotor blade being arranged to rotate about a rotor axis. The rotor blade extends away from the axis of rotation into the field. To reduce the trailed tip vortex at the end of the rotor blades, the fluidic losses, and flow noise, the rotor blade is split in at least two partial blades at a set distance from the axis of rotation and forms a loop. One partial blade extends in the direction of rotation in relation to the rotor blade. The other partial blade extends in a direction opposite the direction of rotation to the rotor blade. The two partial blades are interconnected in one piece at their ends, to encompass a loop surface extending essentially crosswise to the main direction of flow, through which the fluid flows.
22	Apparatus for indicating pitch angle of a propeller blade	US09224523	1998-12-31	US06213713B1	2001-04-10	Carl A. Dickmann
An apparatus for detecting the pitch angle of a propeller blade comprises a sensor and two transmitters. The transmitters are strategically located so as to identify a first fixed reference point on the propeller hub and a second movable point on the propeller blade. The sensor is mounted on a non-moving reference such as the engine housing. The sensor detects the time difference in signal arrival from each magnetic transmitter as they rotate on the propeller assembly and pass by the sensor. The fixed transmitter, although spinning with the propeller hub, does not move relative to the hub itself, and is mounted in a fixed position relative to the hub such as on the bulkhead plate. Each time the fixed transmitter passes by the sensor it generates a reference signal. The movable transmitter moves with the propeller blade as it rotates about the pitch axis thus changing the distance between the two transmitters. After the fixed sensor passes by the sensor, the movable transmitter passes by the sensor generating a second signal such that there is a measurable difference in the time of arrival between the two signals. The measurable difference is indicative of the blade pitch angle.
23	Controllable-pitch propeller, especially for sport boats and other watercraft	US161895	1998-09-28	US5967753A	1999-10-19	Peter Muller
A controllable-pitch propeller for a sport-type watercraft has a push rod eccentrically connected to each blade displaceable in a bore of the propeller hub. The push rod is sealed with respect to the end of that bore by a multifold bellows whose radial flange is clamped by a cap of an axial flange of the housing in which the bore is provided.
24	Apparatus for detecting the pitch of a marine controllable pitch propeller	US232793	1988-08-16	US4900280A	1990-02-13	Ole H. Midttun
The pitch setting of a machine controllable pitch propeller is indicated with a high accuracy by comparing the positions of the portions within the vessel hull of a translating member fastened to the pitch change mechanism within the propeller hub and a non-translating member fastened adjacent one end to the hub and extending essentially free of axial load through the propeller shaft into the vessel hull.
25	Variable pitch propeller	US3575530D	1968-09-05	US3575530A	1971-04-20	HALL CLIFTON W
A propeller having differently dimensioned integrally connected blades positioned on a drive shaft in nonsymmetrical relationship. As the blades rotate with respect to the drive shaft, one of blades changes its blade angle of attack while the other remains at a constant blade angle of attack.

The invention relates to an auxiliary hydrogen system 20 for propulsion of a sailing boat 18. The system comprises: an electric navigation motor 22; an alternator 24; a propeller 26 with variable-pitch folding blades; drive means 28 for the propeller; a desalination unit 30 for intaking sea water and producing demineralized water; an electrolysis unit 32 for intaking demineralized water and producing hydrogen and oxygen in gaseous form; a main tank 34 for storing the hydrogen at low pressure; a hydrogen distribution circuit; at least one fuel cell 36 for converting the hydrogen into electric energy; and means 38 for electrically connecting the system to a permanent electricity network at the port. The propeller blades are designed to assume three different configurations: a configuration for recharging the system during sailing where the propeller blades assume a turbine configuration; a sailing regatta configuration where the propeller blades assume a folded-up configuration; and a motor navigation configuration where the propeller blades assume a propulsive configuration. Moreover the propeller drive means are designed alternatively to: connect the propeller to the alternator, thus defining the sailing recharging configuration; connect the propeller to the navigation motor, thus defining the motor navigation configuration; or keep the propeller mechanically disconnected, thus defining the sailing regatta configuration. The invention also relates to a sailing boat 18 comprising the system described above.
