Abstract: An electronic cigarette has a housing including a battery compartment, a rechargeable battery arranged inside the battery compartment. The battery has two end surfaces opposed along a central axis and a peripheral surface connecting the end surfaces. Battery terminals are arranged on at least one end surface. A holding member exerts a holding force against the peripheral surface of the battery and securely holds the battery inside the battery compartment, even if the size of the battery changes.

Abstract: For the separation of the sheets of a record carrier from a pile (10) in order to feed them to an office machine or a printer, a rolling action device (14) sits on the uppermost sheet (12) of the pile (10). By means of the rolling action device (14), the uppermost sheet (12) is loosened from the following next sheet (20) and is pushed against a stop in the feeding direction. The stop is positioned at an impingement angle of at least 90 degrees in relation to the plane, in which the uppermost sheet (12) is being pushed against the stop. Then the stop is moved upwards so that it could pick upwards the front edge of the uppermost sheet (12). The stop can be built, for instance, of at least one upwards-running belt (22).

Abstract: A method and a device for separating the sheets of a stack are described. At least one flexing device engages at the top sheet of the stack, tensioning or arching the edges of the top sheet. This creates a clearance between the top sheet and a second, lower sheet. A separating edge is inserted into said clearance so that the top sheet can be removed by a transport arrangement.

Abstract: A device for separating sheets (10) of a recording medium stored in a horizontally disposed stack includes an advance roller (16) resting on the stack and following the decreasing height of the stack. The advance roller (16) is drivable in order to acquire the topmost sheet (10.1) of the stack under frictional closure and to slide it for separation with its leading edge up on an obliquity (14). In order to be able to separate sheets (10) of different stiffness, the advance roller (16), while it is driven on the topmost sheet (10.1), drifts from the obliquity (14) until the leading edge of the sheet (10.1) runs up on the obliquity (14). The advance roller (16) is movable vertically. The counter force acting during the driving of the advance roller (16) is additionally supported in a rocker in order to increase the contact pressure against the topmost sheet (10.1) in case of the sheets of great stiffness.
