Abstract: PCT No. PCT/FI90/00009 Sec. 371 Date Aug. 23, 1991 Sec. 102(e) Date Aug. 23, 1991 PCT Filed Jan. 10, 1990 PCT Pub. No. WO90/08283 PCT Pub. Date Jul. 26, 1990.The invention relates to a motor-driven control valve for a liquid, in which a control member (31) effects a rotatory and/or linear motion. In order to achieve an improved torsion moment and controllability, the motion of the control member is produced by means of an ultrasonic motor. In one embodiment, the rotating plate acting as a control member (31) forms directly a mobile part of the ultrasonic motor. An oscillating body (36) is in contact with this part, the oscillations of the body being produced by piezoelectric elements (37). The oscillating body (36) with the piezoelectric elements (37) can be annular, thus surrounding e.g. the material flowing in the pipe. Owing to the invention, a compact and simple solution is provided, and the actuating of the plate does not require as many transmission elements as when usual electric motors are being used.

Abstract: The hollow-section sealing strip of the invention has, viewed in cross-section, a number of identical grooves (8) and a row of channels (9, 10). The channels have different cross-sections, however. The outer channels (9) are basically conical in cross-section with a rounded vertex (91) and a curved base (92). The inner channels (10) are basically circular, part of the circle being formed by a straight line (101). In addition, the side (5) of the hollow-section strip designed to make contact with another, identical strip has two outwards-sloping surfaces (12) forming protruding corners (14). These specially shaped cross-sections produce particularly pressure-resistant sections (11) between the channels (9, 10) in the interior of the strip and strong corner zones (13) between the outer channels (9) and the strip edges (6) adjacent to them, thus giving a particularly effective sealing action against penetrating water.

Abstract: The application relates to a profile system consisting of extruded profiles of metal or plastic. The system, which consists of decorative profiles having a U-shaped cross-section, of connectors (20) and of a clamping element, is assembled with the aid of connectors, without additional measures such as drilling, sawing, stamping and the like. The connectors (20) may be used for two-dimensional structures, or, after completion, also for three-dimensional structures. The free limbs of said connectors are fixed with the aid of special clamping elements, a relative movement being produced between the connector and the decorative profile which leads to close and fixed contact between mutually adjacent decorative profiles. <IMAGE>

Abstract: A dough-stretching roller apparatus is provided to produce a continuous web of dough (7) in a process to manufacture confectionery and bread. The apparatus includes a pair of upper rollers (3), a sensor means (5) that detects the width of dough at the gap between the upper rollers (3), and a controller (11) that controls a motor (8) driving the upper rollers (3) in response to a signal from the sensor means (5). The controller (11) decreases the rotational speed of the upper rollers (3) when the sensors (5) detect that the width of dough is broader than a predetermined width of dough passing through the upper rollers (3), while the controller (11) increases the rotational speed of the upper rollers (3) when the sensors (5) detect that the width of dough is narrower than the predetermined width of the dough passing through the upper rollers (3). Thus, even if the amount of dough supplied from a hopper (2) is unstable, production of a stretched web of dough (7) having a constant volume per unit length can be stably continued. <IMAGE>

Abstract: Closed press section in a paper machine, comprising a compact combination of press rolls. Therein the rolls (16,17,20,21;16A,17,16B,20,21) form press nips (N1,N2,N3) with each other, between which nips the web (W) has a closed draw supported by the face of a fabric (14,30). The press section has a centre roll (20), in whose connection a press nip or press nips (N2,N3) are provided. Around the centre roll (20;20A) a closed loop of a transfer band (30) is passed, on whose outer face the web (W) is transferred, after the last press nip (N3) in the compact combination of rolls, as a closed and constantly supported draw onto the drying wire (25) in the drying section following after the press section. The transfer band loop is a transfer band fabric (30) that substantially does not receive water and does not rewet the web (W). The web-adhesion properties of the outer face of the transfer band fabric (30) have been chosen so that, after the last nip (N3), the web (W) follows the transfer band fabric (30) and so that the web (W) can be transferred as a fully closed draw onto the drying wire (25).
