    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: The invention relates to a method for processing extrudable material, especially for the manufacture of a multilayer extrusion product in an extrusion device, wherein the extrudable material is brought in solid form, advantageously as powder or in granular form, and which includes a central extrusion channel (1) and the stator means (2, 3) and the rotor (4) defining it. The invention concerns also such an extrusion device. In the extrusion device according to the invention it is used an optional number of stator and rotor means (2, 3, 4) arranged packlike alternately one within the other, whereby the extrudable material is first melted during its feed into an annular feed defile (5) advantageously in conical or double-conical form between the stator means (2, 3) and the rotor means (4) after the infeed thereof before the central channel, and thereafter compressed to the final extrusion pressure. The feed defile (5) of the extrusion device according to the invention comprises in the flow direction of the extrudable material first an infeed zone (51), then a melting zone (52) and finally a compression zone (53). The invention relates further to a new extrusion product, which is a multilayer product, and at least one layer whereof includes an interlacing orientation field, in which the plastic is helically oriented or directed forming a reinforcing netlike structure into the product.

    Abstract: The present invention concerns a dielectric film for converting the energy of an electric field or of a magnetic field into mechanical work, orfor converting mechanical work into electric energy, and a procedure for manufacturing the film. The film of the invention consists of a homogeneous, e.g. a film layer (A) foamed to a structure (C) of full-cell type and which has been oriented by stretching it in two dimensions and coated at least in part on one side or on both sides with an electrically conductive layer (B). The film is manufactured by extruding the plastic which has been made to be foams able, into tubular shape, performing intermediate cooling of the tube and reheating it, expanding the heated tube in two dimensions, metallizing the outer surfaces and cutting the tube open to become a film.
