Abstract: A method and device for transferring a measurement signal from a revolving roll used in a paper making machine, in which detectors are arranged in the transverse direction of the roll, preferably uniformly spaced. Measurement signals generated by the detectors are passed to a measurement signal reading unit for reading the measurement of the detectors which is installed preferably at the end of the roll. From the measurement signal reading unit, the signals are transmitted wirelessly further as telemeter signals to a reading unit which is placed outside the roll and connected to a PC or equivalent computer. In the measurement signal reading unit for reading the measurement of the detectors, a transponder is arranged into which an unique code is coded for each detector. The signals are processed in the entire measurement process as analog signals.

Abstract: An exhaust gas purifying apparatus capable of exhibiting an excellent exhaust gas purifying capability and restoring the capability to an initial level even after running for a long period of time. An electrification mesh section electrostatically negatively charges useless particulates contained in exhaust gas and a purification filter section adsorbs thereon the particulates thus charged, resulting in the particulates being separated from the exhaust gas. Also, when the purification filter is made of carbon fiber or carbon particles or the denitration filter section is additionally provided, a reduction in concentration of nitrogen oxides in the exhaust gas is accomplished as well. In a reactivation unit, cleaning liquid cleans the purification filter section to remove useless particulates therefrom, so that an exhaust gas purification capacity of the exhaust gas purifying apparatus may be restored to a level substantially equal to an initial level thereof.

Abstract: A rib construction for a draining device in a paper machine in which a loading rib is used to support and/or to load a wire or wires in a paper machine and/or to doctor water from the face of a wire or wires. The rib is loaded by pressure of a medium.

The roll mantle is supported on the roll axle by the glide bearing elements which act radially substantially in the principal loading direction in opposite directions and which are provided with a device for regulating the braking pressure provided by a second pressure medium, so that in the principal loading direction, the roll mantle is allowed to move over a certain distance.

Abstract: A process for producing polyethylene compositions in the presence of a catalytic system of ethylene polymerizing catalyst and cocatalyst in a multistage continuous reaction sequence consisting of successive liquid phase and gas phase polymerizations is disclosed. In the first step of the process, ethylene and optionally hydrogen and comonomer are polymerized in a first loop reactor in a low boiling hydrocarbon medium in the presence of ethylene polymerizing catalyst and cocatalyst. The reaction mixture is then removed and then transferred to a second loop reactor where polymerization is continued by addiing ethylene, hydrogen and optionally inert hydrocarbon, comonomers and cocatalysts. Thereafter, the reaction mixture is removed from the second loop reactor along with an essential part of the reaction medium and transferred to a gas phase reactor where polymerizing is continued in the presence of added ethylene and optionally hydrogen, comonomers and cocatalysts to form an end product.
