    Abstract: An electromechanical transducer comprising at least one transducer element which has a multilayer structure comprising at least two layers such that the transducer element is capable of changing its thickness. The transducer element allows air to flow inside the transducer element in the direction of thickness thereof and inside and out of the transducer element through at least one surface of the transducer element in the direction of thickness of the transducer element. The transducer element can be used e.g. for transforming energy from mechanical energy into electric energy and/or vice versa.

    Abstract: A process for fabricating a foamed plastic product. The process includes a plastic film that is prefoamed in order to introduce lamellar discontinuities such as prefoamed bubbles. The film is pressurized by a gas under a positive pressure causing the gas to diffuse into the film, forming a second film. Further, the second film is inflated in order to form the foamed plastic product. The second film is inflated by heating the second film at a temperature below the melting point of the second film and under a reduced pressure.

    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 electromagnetic or electrostatic energy into mechanical work, and a procedure for manufacturing the film. The film of the invention consists of a homogeneous film layer foamed to be of full-cell type and which has been oriented by stretching it in two directions and coated at least in part on one side or on both sides with an electrically conductive layer. The film is manufactured by extruding the plastic which has been made to be foamable, into tubular shape, performing intermediate cooling of the tube and reheating it, expanding the heated tube in two directions, metallizing the outer surfaces and cutting the tube open to become a film.

    Abstract: An aircraft which includes elements providing air circulation and directing the circulation along a housing. Different operational stages of the aircraft such as take off and level flight are achieved by using the same functionally inter-connected elements. The circulation is achieved by fan elements that allow adjusting the blow direction and the blowing force of the flow. A stagnation point (SP) associated with the circulation is also formed if necessary below the housing and the aircraft can be steered by controlling the circulation and the position of the stagnation point (SP).
