Abstract: A system for forming a controlled safety area for a manipulator which system comprises a control unit being arranged to monitor the controlled safety area in order to prevent human entering to the controlled safety area to be hit by the manipulator working within the controlled safety area. The system according to the invention comprises at least one laser scanner being arranged to form at least one laser scanning wall such that the controlled safety area is divided in to a high grade safety area in between the at least one laser scanning wall, and to low a grade safety area outside the at least one laser scanning wall. The system comprises also at least one area detecting laser scanner arranged to detect humans at least in the low grade safety area around the high grade safety area.

Abstract: A portable inhalator device includes a housing with a mouthpiece for a user; a gas conduit coupled to the mouthpiece and configured to guide inhaling and exhaling gas flow within the device; a pressure sensor configured to monitor the gas flow in the gas conduit and to provide pressure differential signal for indicating direction of the gas flow through the gas conduit; a detection sensor configured to monitor the gas flow in the gas conduit and to provide characteristics signal for indicating composition of the gas flow through the gas conduit; and a dispenser configured to dispense a drug to the gas conduit.

Abstract: The operation of a doctor assembly (16) in a paper machine is monitored. In case of a malfunction, the paper machine's (10) control devices (14-14?, 15) are used to carry out the necessary measures for eliminating the malfunction and carrying out repair and/or protective measures. In addition, detector devices (20) are arranged in connection with the doctor assembly (16), to detect a malfunction. The detector devices (20) are connected to the control devices (14, 14?, 15) of the paper machine (10), in order to carry out the said measures automatically. The invention also relates to doctor assemblies in a paper machine for implementing the method.

Abstract: A multi-cylinder dryer of a paper machine, has at least one drying cylinder (10) and at least one roll (11, 12) located at a different height to the cylinder and at a distance to it in the machine direction. A paper web (14) travels from the drying cylinder (10) to this roll (11, 12). Dry air is brought to the dryer through a beam (13) located in front of the web (14) in the machine direction, the air is directed by means of nozzles (33) in the beam into a throat (21) between the drying cylinder (10) and the web (14) mainly to intensify the drying effect. A doctor (27) keeps the surface of the drying cylinder clean. The beam (13) forms with the roll (12) a smooth, high channel (25), at least on the side of the roll (12), for the passage of the web during a disturbance.

Abstract: The invention relates to an arrangement in a multi-cylinder dryer of a paper machine, which arrangement includes at least one drying cylinder (10) and at least one roll (11,12) located at a different height to the cylinder and at a distance to it in the machine direction, the paper web (14) travelling from the drying cylinder (10) to this roll (11, 12). Dry air is brought to the dryer through a beam (13) located in front of the paper web (14) in the machine direction, in which dryer the air is directed by means of nozzles (33) arranged in the beam into a throat (21) between the drying cylinder (10) and the paper web (14) mainly to intensify the drying effect. A doctor (27) is arranged in, or in connection with the said beam (13) to keep the surface of the drying cylinder clean. The beam (13) is arranged to form with the roll (12) a smooth, high channel (25), at least on the side of the roll (12), for the passage of the web during a disturbance.

Abstract: The invention relates to a method for monitoring the operation of a doctor assembly in a paper machine. In the method, the operation of the doctor assembly (16) is monitored. In case of a malfunction, the paper machine's (10) control devices (14-14′, 15) are used to carry out the necessary measures for eliminating the malfunction and carrying out repair and/or protective measures. In addition, detector devices (20) are arranged in connection with the doctor assembly (16), to detect a malfunction. The detector devices (20) are connected to the control devices (14-14′, 15) of the paper machine (10), in order to carry out the said measures automatically. The invention also relates to doctor assemblies in a paper machine for implementing the method.

Abstract: The invention relates to a doctor apparatus (10) in connection with a roll (T) in a paper or board machine. The doctor apparatus (10) comprises a doctor beam (12) of lightweight construction and that the doctor beam (12) is arranged to pivot on bearing means (13a1, 13a2 . . . ) (pivot movement arrow L1). In connection with the doctor beam there are loading members (14a1, 14a2), a relative linear movement taking place between the loading members (14a1, 14a2) and backup surfaces (12′, 15a′) when the doctor beam (12) is being oscillated.
