Abstract: Disclosed are solutions for an autonomous vehicle to real-time detect and determine dynamic and/or obscured obstacles to support navigation and services to within a desired proximity of said obstacles. Certain such implementations are specifically directed to autonomous mowers, for example, capable of real-time object detection to determine location and orientation of solar panels in a solar farm, for example, and based on the location and orientation of such solar panels further determine the location of their corresponding posts that may be otherwise obstructed from direct detection by the autonomous mower's other sensing systems possibly due to vegetation growth around the posts or other reasons.

Abstract: Method for compensating for uneven shrinkage in a paper web in the press and drying sections of a paper machine, in which there is at least one open draw. In the method, a flow guide/guides are used in the head box, by means of which the machine direction orientation tendency of the fibres is reduced in the edge areas of the web and the angle of detaching of the web from the centre roll is adjusted, by directing onto the web an air jet that is located in the cross direction and the pressure of which can be adjusted in the said direction.

Abstract: An arrangement and method for improving runnability, and dryer section length, by using a vertical impingement dryer before a first dryer cylinder of a group of dryer cylinders. After a pressing section, the web is dried with a pre-impingement dryer, closely followed by a vertical impingement dryer, which is closely following by the first dryer cylinder. The pre-impingement dryer and vertical impingement dryer of the first dryer cylinder to have a drying temperature of approximately 80° C. with no undesirable sticking to the dryer cylinder. The pre-impingement dryer can be arranged to dry a first side of the web, and a vertical impingement dryer after the first dryer cylinder is arranged to dry a second side of the web. The impingement drying takes place directly against the web without an intervening fabric.

Abstract: Fibrous stock is supplied by a paper or board machine headbox (1) between looped forming wires (11, 12). Water is removed in a two part first dewatering zone (Z1), the first part formed by a suction forming roll engaging a forming wire (12) and the second part formed by a fixed forming shoe engaging opposite a forming wire (11). The wires (11, 12) are guided so the first dewatering zone causes essentially non-pulsating dewatering in the stock. Water is removed in a second dewatering zone (Z2) formed by fixed dewatering blades (21) on the other side of the wires (11, 12) and supported against the stock therebetween (21) and on the opposite side of the wires (11, 12) by dewatering blades (24), loaded in a controlled manner against the fixed dewatering blades (21) at gaps (22) between these so that pulsating dewatering is caused in the second zone (Z2).

Abstract: A twin-wire former in a paper machine has two forming wire loops (10, 20), which define between themselves a twin-wire zone. At least one dewatering box (30) is located inside one of the wire loops (10, 20) to remove water through the wire from a web (W) being formed. At least one loading blade (40) is located opposite the dewatering box (30) inside the other wire loop (20; 10) in contact with the other wire. The dewatering box (30) includes at least three successive dewatering zones (30a, 30b) in which every second zone (30a) has a vacuum (p) and every second zone (30b) is vacuum-free. The at least one loading blade (40) is placed inside one of the wire loops (20; 10) at a location where it is opposed by a respective vacuum-free zone (30b), which is preceded and followed by a vacuum zone (30a).

Abstract: A twin-wire former of a paper machine, for high speed paper machines whose web running speed is of an order of from about 1600 m/min to about 2500 m/min. The former includes a carrying wire guided in a loop and a covering wire guided in a loop to define a twin-wire zone and an inlet or forming gap between the wires. A pulp suspension layer or a pulp suspension jet is fed into the inlet or forming gap through a discharge duct of a headbox. The former also includes, as a combination, a first forming-suction roll arranged proximate the forming gap in a loop of one of the wires and a second forming-suction roll arranged inside the loop of the wire opposite to the wire inside whose loop the first forming roll is arranged. The forming-suction rolls have suction zones over which the twin-wire zone is curved on certain sectors. In the suction zones, the vacuum levels are arranged adjustable independently from one another, and possibly relative to one another, so as to minimize the unequalsidedness of the web.
