A form-adaptable electrode structure in layer construction includes at least two conductor layers, between which an insulating layer is disposed, the conductor layers having first and second electrode strips arranged in each case in parallel, and the electrode strips of the first conductor layer being arranged at an angle with respect to the electrode strips of the second conductor layer, so that a net-like structure is formed, and the first electrode strips of the first conductor layer being conductively interconnected with the first electrode strips of the second conductor layer, and the second electrode strips of the first conductor layer being conductively interconnected with the second electrode strips of the second conductor layer via the insulating layer at intersections of the net-like structure.

A tilt and swivel positioning device for positioning a servo flap in a rotor blade. The device contains a tilt element and a bearing element. The tilt element is swivellably attached to the bearing element. The bearing arrangement has a convex roll-off surface resting against a concave roll-off surface. The radius of the concave roll-off surface exceeds the radius of the convex roll-off surface.

A device directed to a continuous control of piezoelectric actuators for fuel injection systems. A piezoelectric actuator is provided for controlling the valves of i.c. engines with a constant actuator function under different conditions of use and operation. The electrical manipulated variable is a length-changing electrical charge transmitted to the piezo stack that is generated by a charge generator and is controlled in reference to the charge by a control unit. The use and operation conditions of the i.c. engine acting on the piezo actuator are detected by sensors and fed to the control unit to parameterize the charge control. With these features, a continuous control of a piezoelectric actuator in a fuel injection system for i.c. engines is achieved, in which the length of its piezo stack can be changed with an electrical manipulated variable to actuate a fuel valve in the injection system
