Abstract: A multi-layer web formation section has two successive wire units (300, 310) with a common wire (11). A first headbox (100) supplies fiber pulp to the first wire unit (300) forming a first partial web (W1). A second headbox (110) supplies a new fiber pulp layer to the forward end of the second wire unit (310) atop the first partial web. A first non-pulsating dewatering zone (Z1b) in the forward end of a two-wire stretch of the second wire unit (310) has a first formation shoe (200b) with a curved cap (201) placed on the side of the new layer having openings (202) extending through the cap (201) with an under-pressure (P) affecting therethrough. A two-wire stretch of the second wire unit (310) has a second pulsating dewatering zone (Z2b) formed by fixed dewatering lists (210b), between which there are gaps (220b) and an under-pressure (Pb) affecting in these.

Abstract: A multi-layer web formation section has at least two successive wire units (300, 310). First and second headboxes (100, 110) supply pulp suspension jets to the forward end of the first wire unit (300) and the second wire unit respectively to form a first partial web (W1) and a second partial web (W2) which are joined at a joint (N1) between the second wire unit (310) and a bottom wire (11). A first non-pulsating dewatering zone (Z1b) in the forward end of a two-wire stretch of the second wire unit (310) is formed by a fixed formation shoe (200b) having a curved cap (201) placed against one side, having openings with an under-pressure applied. A two-wire stretch of the second wire unit (310) has a second pulsating dewatering zone (Z2b), formed by fixed dewatering lists (210b) in the cross machine direction with gaps (220b) therebetween with an under-pressure (Pb) applied.

Abstract: The invention is concerned with an antenna arrangement adapted to a mobile terminal and division of frequency bands between different antennas. The antenna arrangement enables the terminal to operate worldwide in networks applying different frequency bands and technologies, as a so-called multi-band terminal. In the antenna arrangement the frequency bands of the antennas are arranged for each antenna in a way that the bands fill an optimal frequency area, thus accomplishing smaller total volume for the antennas and a good performance.

Abstract: The invention relates to a ground arrangement of a device using wireless data transfer. In order to improve the electric properties of the device and to minimize the SAR value of the device, at least one electrically conductive additional ground lead (73-75) is formed in the device in addition to the actual ground lead (72). In between the ground lead and the additional ground lead, a galvanic coupling is automatically established, when a predetermined switching criterion is fulfilled, and the aforementioned galvanic coupling is automatically released, when a predetermined release criterion is fulfilled. This enables one to change the ground configuration of an antenna such that it is as suitable as possible for the transmission and reception circumstances each time existing.

Abstract: The invention relates to a terminal employing wireless data transfer, comprising an enclosure structure consisting of at least one enclosure part (30), (40), (50), (60), an antenna (80) and a feed conductor (92) for receiving a signal from the antenna and/or feeding a signal into the antenna. By applying the invention, a device construction is achieved that makes it possible to improve the EMC properties of the device in a simple way and to improve the electric performance of the antenna of the device, especially to increase the frequency band of the antenna.

Abstract: The invention concerns an equipment and a method in a twin-wire former, in which a partly pre-drained or non-drained fiber stock is passed to between the forming wires of the web former in the vicinity of the former roll (11) or of a water drain box, in which connection water is drained out of the stock web by means of the former roll (11) or the water drain box. The twin-wire former comprises a rib (20) in connection with the former roll (11) or the water drain box in the lateral area of the wires (H2), which rib has been fitted to control the running of the second forming wire H2) passed from the gap roll. By means of the rib (20), in the lateral area of the wire runs, the point at which said forming wire (H2) reaches contact with the first forming wire in connection with the former roll (11) or the water drain box is shifted further away in the machine direction. The rib (20) is an oblong structure, which has a maximal height (Hmax) in the middle area of the rib (20).
