Title: Rotational speed control for small wind turbine - maintains rotor speed and generator voltage independent of wind speed above specific level
Inventor: WIENPAHL WOLFGANG
IPC: F03D7/02
Filed: 1974-09-20
Abstract: In some conventional designs, speed regulation of generator-rotors is effected by adjusting the blades using the centrifugal moment of weights. This results in a marked variation in rotational speed as well as charging current whenever the wind speed and load fluctuates. To overcome thus the rotor blades are rotated spirally and mounted on hollow pins located radially to the axis. The blades are hinge-linked to a central disc each via a guide ball bearing in order to avoid the danger of an imbalance in the rotor. In addition variable friction coefficients for the rotor blade mountings are also employed.

Title: Engine whose piston rotates as it reciprocates - has two opposed cylinders with pistons moved from same crank
Inventor: HARR EWALD
IPC: F01B9/02
Filed: 1976-03-16
Abstract: The engine has a crankshaft (3) with a diagonal crank (7) between two webs (4, 5). There are two opposing cylinders (1, 2) perpendicular to the axis of the shaft. Each cylinder contains a piston (9, 10) which reciprocates in the cylinder. The piston has an offset leg (12, 13) which extends down one side of the cylinder and is connected to the crank (7) by a link (14, 15). The link consists of a sleeve (16, 17) riding on the crank with projecting stubs (17) at right angles to the crank. These stubs fit in radial slots in the base of the cylinder leg (12, 13). As the crankshaft revolves the link causes the piston to reciprocate and rotate at the same time. The piston legs are offset and do not therefore interfere with each other.
