Abstract: The procedure and the apparatus serve for the control of a respirator device which is used for the supply of breathable gas to a patient. At least one sensor for the capture of the time-wise evolution of at least one respirator-treatment parameter is provided. The sensor can be arranged in the area of an air delivery which encompasses a respirator device as well as a connecting installation. The sensor is connected to an analyzer which carries out a pattern recognition and which is connected to a control for the modification of at least one respirator-treatment parameter. In order to implement the pattern recognition, one captures—at least at intervals—the time-wise evolution of at least one of the respirator-treatment parameters.

Abstract: Process and apparatus for cutting a running material web in which the material web is wound onto several winding cores in succession, such that winding of the material web onto a new winding core begins after a predetermined diameter has been attained in a wound roll formed on an old winding core. The process includes moving the new winding core between a winding roll and the wound roll, such that the material web is fed onto the wound roll from the winding roll.

In this manner, the running material web can be completely cut.

Abstract: Winding machine and process for winding a material web, in particular a paper or cardboard web, onto a reel. The material web is guided by a carrying drum that can be supplied with suction, and a nip is formed between the carrying drum and the reel. The carrying drum, which has a perforated casing and/or is provided with circumferential grooves, is supplied with suction by way of at least one external suction box. The suction box is disposed with at least one suction opening opposite the circumference region of the carrying drum that is not wrapped by the material web. The suction box has at least one sealing element that cooperates with the carrying drum in the vicinity of the suction opening.

Abstract: Method for winding a material web onto a reel in an apparatus that includes a rotatable feed roll, a carrying drum, a discharge roll and a pulper. Winding device for winding a material web onto a reel, said winding device including: a feed roll, a carrying drum, and a support belt which is adapted to guide the material web over the feed roll and the carrying drum. An external vacuum device is positioned adjacent a circumferential surface of the carrying drum which is not contacted by the support belt and the material web and a winding nip is formed between the carrying drum and the reel. A discharge roll is provided for guiding the support belt, and the discharge roll is located in the vicinity of a pulper, downstream from the carrying drum, relative to a web run direction. The discharge roll is also adapted to divert at least a portion of the material web to the pulper before feeding the material web to the reel.

Abstract: Reel winding device and process for supporting a winding reel. The device includes two support rolls arranged to form a winding bed adapted for receiving a winding reel, a compressed air support device having a pressure chamber arrangement with end sealing elements, and at least one of the end sealing elements including a sealing diaphragm arrangement that cooperates with a circumference of the winding reel.

Abstract: A winding machine for a material web, particularly of paper or cardboard, the web being rolled onto a reel core for forming at least one round reel. At least two supporting devices support the wound reel. The first supporting device is formed by a first supporting roller. The second supporting device comprises at least a second supporting roller and comprises at least one lowering device that lowers to let the wound reel move off the first roller. The lowering device can be pivoted about an axis that runs essentially parallel to the longitudinal axis of the first roller. The second supporting device is moveable to a first position where it supports the winding on process or a second position where it provides support over a circumferential area of the reel during the remainder of the winding. The second supporting device is moveable, e.g., by a piston-cylinder unit, to provide support as the wound reel increases in diameter.

Abstract: The winding machine of the invention includes two parallel wound web roll support rollers which are spaced apart and on which the roll being wound is supported. The gap between the support rollers and below the supported wound roll is to be pressurized. A pressure chamber is defined by the support rollers, the wound roll above, and from below by a cross member which bridges over the distance between the support rollers and closes the bottom of the gap. End walls close the ends of the chamber. The cross member is movable between a sealing position where it is in contact with, or at least is sealed with, the two support rollers and bridges the gap between them to an open position where it opens the gap between the support rollers. The cross member is movable either down out of the gap, laterally out of the gap, or a combination of both, by reciprocating swinging, or oblique movement, and the like.

Abstract: A method of controlling a respirator for therapeutic treatment of sleep aa includes the step of continuously measuring a) a phase angle of a time difference between respiratory flow and respiratory pressure of a patient and b) a pressure amplitude of the patient. The individual respiratory resistance is determined based on the measured pressure amplitude by oscilloresistometry. The respiratory gas pressure is controlled based on the phase angle, the pressure amplitude, and the respiratory resistance. Significant changes of the phase angle are filtered from the signal of the phase angle. A control signal is produced based on the significant changes for controlling the respiratory gas pressure.

Abstract: For controlling a respirator for treatment of sleep apnea, a patient's oscillatory pressure amplitude, which corresponds to a patient's breathing resistance is continuously measured, and the individual breathing resistance value (base value) of a patient's pressure amplitude is determined, by oscilloresistometry (oscillatory resistance measuring=ORM). If deviations from this base value occur, the patient is supplied with respiratory gas under pressure and the gas supply is terminated or minimized as soon as the base value is again reached or almost reached.
