Abstract: The invention relates to a device for a wind instrument, comprising a mouthpiece (1) which encloses a sound chamber (12) and which has a window (2) connected to the sound chamber (12), and comprising a reed (6) which comprises a plastic material, which has a shaft portion (8) connected over its surface to a support (5) of the mouthpiece (1), and a movable free end portion (9) that can be placed on bordering surfaces (4; 4?, 4?, 4??) of the window (2). The reed (6) has sealing means (14) on a support surface (10) facing the boundary surfaces (4; 4?, 4?, 4??) of the window (2) and/or the mouthpiece (1) has sealing means on at least one of the boundary surfaces (4; 4?, 4?, 4??) of the window (2) in order to seal an air flow between the reed (6) and the mouthpiece (1). The invention also relates to a mouthpiece (1) and a reed (6) for such a device.

Abstract: The invention relates to a device (40) for magnetically axially supporting a rotor, which rotor comprises a thrust bearing plate (32) connected to the rotor, in a magnetic thrust bearing (54) having at least two independently controllable bearing branches (3, 4, 41) which each comprise at least one coil (5, 42), wherein magnetic flux isolation of the bearing branches (3, 4, 41) is provided, which flux isolation consists in that at least two of the bearing branches (3, 4) are arranged one after the other in the circumferential direction and have a single common pole (9) which has a circularly closed circumference, the center point of which is arranged on the axis of rotation (35) of the rotor, wherein the coils (5) surround pole segments (11) connected to the common pole (9) and wherein the common pole (9) is arranged either radially inside or radially outside of the pole segments (11), and/or in that the thrust bearing plate (32) is divided into at least two coaxial plate parts (46, 61) which are associated w

Abstract: Disclosed is a flywheel (13) comprising a rotating element (13?) which rotates in relation to an axis of rotation and includes a radially outer flywheel mass member (24) that adjoins an inner shaft connection part (26) and tapers in the radial direction such that hollow projecting end pieces (24?) are formed. The external face of the outer flywheel mass member (24) has a radial indentation (25) that extends all around the flywheel mass member.

Abstract: What is described is an actuator system (2) comprising at least one actuator (29, 29?) and an associated control system (8) which is designed for at least two operating modes, at least one of which may be deactivated, whereby one of the operating modes is a high efficiency operating mode.
