Abstract: A method operates a hearing device in which an input signal is created based on an ambient sound by a microphone. An output signal is provided based on the input signal, and an output sound is emitted based on the output signal by a receiver. The non-processed ambient sound present in the area of the receiver is identified, and the ratio between the non-processed ambient sound and the output sound is identified for different frequency bands. An amplitude of the output signal is changed for the frequency band in which the ratio is between an upper limit value and a lower limit value.

Abstract: A printing unit has at least two lateral frame parts. The distance between which can be changed, relative to each other, in a horizontal direction. Each frame part receives a printing group or parts of such a printing group. At least one of the lateral frame parts is displaceably supported for movement between a functional position, in which the lateral frame parts meet and are affixed relative to one another, and an open position in which the lateral frame parts are positioned at a distance from each other. The support of the at least one movable lateral frame part has at least one sliding surface which is made using a composite plastic that is composed of multiple materials.

Abstract: A printing unit has at least two lateral frame parts, the distance of which can be changed relative to each other in a horizontal direction. Each of the frame parts receives a printing group or parts of a printing group. At least one of these lateral frame parts can be displaced between a functional position, in which the lateral frame parts meet, and are affixed to each other, and an open position in which the lateral fame parts are positioned at a distance from each other. The displaceable frame parts can be displaced by the use of a cylinder/piston arrangement in which a single such cylinder/piston arrangement is disposed for displacing the lateral frame.

Abstract: A printing unit is comprised of at least two side frame parts whose distance, relative to each other, can be modified in a horizontal direction. Each printing unit receives at least one printing group or parts of a printing group. At least one of the side frame parts can be moved between a closed functional position, in which the side frames are moved together and are fixed relative to one another, and an open position, in which they are spaced from each other. In order to fix or to secure the side frame parts relative to one another, at lease one closure device is provided. The at least one closure device is comprised of a cylinder that can be used to pretension the side frame parts into the closed functional position. The cylinder carries a piston rod that is adapted to carry out a stroke movement. The closure device is configured as a swivel tensioning element.

Abstract: The invention relates to a device for conveying sheetlike articles, in particular printed sheets, by which conveyed sheetlike articles may optionally be fed to various conveying routes, various delivery stacks being provided in particular at the end of the conveying routes. The device includes at least one conveying module (1, 2, 3, 4) having at least one continuously revolving suction belt (11) which exerts a negative pressure on the underside of an article (200) to be conveyed, and which conveys the article (200) from the start to the end of the conveying module (1, 2, 3, 4). At least one conveying module (2) is designed as a mechanical switch point in order to reroute a conveyed sheetlike article (200) in its conveying route. The invention further relates to a method for operating such a device.
