Abstract: An antenna presenting improved polarization isolation is disclosed which presents at least two columns of rectangular micro-strip or patch elements which each has a single, linear polarization. Each column presents radiation elements of either about +45 or -45 degrees. At least two such columns are combined such that an antenna is obtained which then becomes dual polarized. Furthermore the columns are arranged such that the patches are alternately sidewise displaced to form a herringbone pattern. In other words a next patch of one column is placed on the symmetry lines through nearby patches of the other column. In this way the coupling between the patches is minimized and a high isolation is achieved between the two states of polarization. The achieved two linear states of polarization are utilized separately for polarization diversity. Furthermore in the preferred embodiment the structure of the antenna is designed to compensate for pointing errors between the columns due to unsymmetrical ground-planes.

Abstract: A method and an arrangement for controlling rock drilling on the basis of a pressure acting in a pressure conduit of a rotation motor of a drill rod. In the method, the pressure acting in the pressure fluid conduit of the rotation motor is measured during the rotation when the drill bit does not touch the rock to be drilled, and the control is carried out thereafter on the basis of the difference between the pressure value measured during the drilling and the idle pressure value. In the arrangement, the rock drilling machine comprises a control unit that measures the pressure acting in the pressure fluid conduit of the rotation motor when the drill rod is rotated so that it does not touch the rock to be drilled and stores it in the memory and controls the rock drilling machine during the drilling on the basis of the difference between the pressure value measured during the drilling and the idle pressure.

Abstract: A board machine comprises wet and press sections. The wet section has a first forming unit arranged to form a printable surface layer. The unit has a wire to transfer a multilayer cardboard web to upper press felt with the printable surface layer facing downwards to contact a lower press felt. The lower press exerts greater adhesion force and encompasses a lower roll by an angle.  A board machine comprises wet and press sections (4, 5). The wet section includes a first forming unit (7) to form a first layer and additional forming unit(s). The first forming unit has forming wire(s) (9) which runs in an extended loop up to the press section to form a pick-up point for a multilayer cardboard web. The additional forming units (8) form additional layer(s) and couch the same with the first layer on the extended forming wire to form the multilayer cardboard web. The press section includes at least one double-felted press having an upper press element (47) and a lower press element (48) in a form of a press roll, an upper press felt (49) running in a loop around guide rolls (53) and a pick-up roll, and a lower press felt (52) which also runs in a loop around the guide rolls. The upper and lower press elements create a press nip with each other. The pick-up roll is arranged at the pick-up point to transfer the multilayer cardboard web into the upper press felt. The first forming unit is arranged to form a printable surface layer and arranged with the extended forming wire for transferring the web to the upper press felt of the double-felted press in which the printable surface layer faces downward to contact the lower press felt in the press nip. The lower press felt has a finer web-containing surface to exert greater adhesion force on the web. The lower press felt encompasses the lower press roll by a pre-determined minimum sector angle measured from a point in the press nip intersected by the press line which is defined for a roll and a shoe press, respectively. An Independent claim is also included for a method of manufacturing a multilayer cardboard web with a printable surface layer in a board machine.

Date Nov. 6, 1997The invention relates to a process for the thermomechanical surface treatment of flat webs of material, particularly those made of paper and carton, and to agents for performing said process. According to the process of the invention, adhesion between the flat web of material and the surface of the tool used in thermomechanical surface treatment, e.g., a roll or a press, is reduced or prevented by using an abhesive agent, which contains dicarboxylic dialkyl esters and/or diisoalkyl esters of C2-C12 dicarboxylic acids with C1-C13 n- and/or iso-alkanols as component with abhesive effect. The abhesive agent is preferably employed as an oil-in-water emulsion and is either applied to the surface of the tool used in said thermomechanical treatment or is added to the impregnating fluid or the paper coating mass or the moistening water or the steam in pre-moistening, or is applied to the paper web after the impregnating unit or directly before the smoothing roll. A steam-volatile abhesive agent is preferably used which then is metered through the steam line for steam moistening.
