    Abstract: The invention relates to a method and an equipment for attenuating sound in a duct. Sound propagating in a duct is detected by means of a detector (2) and attenuated by using two successive monopole elements (3, 4) in such a way that both elements function as a dipole approximation and the elements are also used to approximatively produce the monopole radiation needed. A dipole control signal is fed to both elements (3, 4) at a phase shift which is 180° between the two elements. In addition, a monopole control signal is fed to the same elements (3, 4), only this time cophasally. Total volume velocities produced by the two elements (3, 4) are combinations of the portions obtained from the monopole and dipole sources.

    Abstract: A film is extruded from plastic material by an extruder. The film is orientated after extrusion. Material is mixed into the plastic so that when the plastic film is stretched, cavitation bubbles are formed in the material particles mixed into the plastic. During the orientation, gas is arranged to the plastic film under high pressure so that the gas diffuses in the cavitation bubbles and causes overpressure in them. Thus, it is possible to make a thin foamed film with a foaming degree over 70%.

    Abstract: A method and an apparatus for extruding material, the material being extruded with an apparatus comprising at least one rotatable rotor and at least one stator, the rotor and the stator comprising grooves, whereby the grooves make the material move through the apparatus when the rotor is rotated. The rotor and stator surfaces facing each other have a wavelike cross-section, and the grooves are so arranged that at the ridge of a wave the depth of a groove reaches its maximum, and at the bottom of a wave the depth reaches its minimum. The bottom of the wave in the rotor is at the ridge of the wave in the stator and vice versa. This makes the material move alternately from a rotor groove to a stator groove, and back.

    Abstract: The invention relates to a method of and an arrangement for damping a wall movement. In the invention, the strength of an electric field between a surface of a wall and an air-permeable mass plate parallel with the surface is controlled to provide a force opposite to the wall-moving force. A sound wave, for instance, may cause a force moving a wall back and forth, which force is cancelled by the opposite force by means of the method and arrangement of the invention, whereby the movement applied to the wall by the sound wave can be stopped.

    Abstract: An extruder including: (a) at least two concentric stators including (i) an inner stator having at least an outer surface that is at least mostly conical and (ii) an outer stator having at least an inner surface that is at least mostly conical; (b) at least one rotatable rotor that is at least mostly conical; and (c) a supply conduit for supplying material into a space between the stators. The at least one rotatable rotor being disposed in the space between the inner stator and the outer stator. The at least one rotor includes a plurality of ducts that define passages through which material can flow from the space to an interior of the rotor. Each of the plurality of ducts defines an opening or groove that opens into the space. The supply conduit has a conduit end defining an orifice. The conduit end is disposed with respect to the at least one rotor such that, as the at least one rotor rotates, successive of the duct ends pass in proximity to the conduit end with successive portions of the openings or grooves aligned with the orifice to permit a flow of material from the conduit end through the successive portions to the interior of the at least one rotor. The duct ends and the conduit end are arranged and disposed in the extruder such that an area of the successive portions of the openings or grooves aligned with the orifice to permit said flow of material remains substantially constant throughout rotation of the at least one rotor.
