    Abstract: A procedure for controlling the imprint in reproductive printing. With a view to providing a versatile printing control system, and one which eliminates the maximum of errors, the invention is mainly characterized in that by means of an optical system is formed an image signal consistent with the imprint and which is compared with a set-point image signal produced in one way or another, from the result of comparison thus obtained being formed an electrical differential signal, which according to the feedback principle controls the formation of the imprint of each object under examination.

    Abstract: The invention relates to a method and an apparatus for sound processing, where sound is attenuated by measuring it and by producing with an actuator a sound field of opposite sign in view of the original sound field. A desired value signal (I) is supplied to the actuator which reproduces the signal. To the actuator is attached a sensor, measuring sound pressure, and the difference of the sensor signal (B) and the desired value signal (I) is applied as high gain feedback to the actuator. As a consequence, sound not pertaining to the desired value signal (I) can be attenuated in a simple manner, and sound in accordance with the desired value signal (I) can be produced simultaneously with the same apparatus.

    Abstract: A method of steering an aircraft, and an aircraft comprising a supporting structure, at least one utility space, at least two propellers whose axles are arranged horizontally, and a driving mechanism to rotate each propeller. The blade angles of at least one propeller of the aircraft are adjusted as a function of a rotation angle of the propeller such that the blow power of the propellers provides the aircraft with a lifting force, and after take-off of the aircraft the blade angles of the propellers are adjusted such that the blow power of the propellers provides the aircraft with horizontal flight.

    Abstract: A method and an apparatus for treating waste material. The apparatus has a conical rotatable rotor (3) placed between stators (1, 2). At least the stators (1, 2) have recesses (9) from which the material in the apparatus can be discharged when the rotor (3) is rotating. The rotor (3) has several openings (8a, 8b) in the axial direction of the apparatus through which openings at least some of the waste material passes. The edges of the recesses (9) and the openings (8a, 8b) of the rotor (3) are sharp so that the waste material supplied to the apparatus is ground by means of the sharp edges when it passes through the openings (8a, 8b).
