In an exemplary embodiment, a seal device (10) that seals between a housing (11) and a rotation shaft (20) passing through the housing (11) includes: a floating ring (15) arranged with a gap h with respect to the rotation shaft (20), a seal portion (14) formed by bringing one end face of the floating ring (15) into contact with the housing (11), and a space portion j provided between the floating ring (15) and the housing (11), and the floating ring (15) includes bias means that contactlessly biases the floating ring (15) to the seal portion via the space portion j. The seal device in which the floating ring follows movement of the rotation shaft is capable of exerting a sealing operation so that vibration of the rotation shaft can be reduced.

A magnetic seal system adapted for use between a support structure and a rotatable shaft. The seal system includes a rotating annular seal assembly surrounding the shaft and rotating therewith, which includes an annular seal, and a non-rotating biasing assembly sealingly mounted to the support structure around the shaft and axially engaging the annular seal assembly. The biasing assembly includes an annular magnet unit axially displaceable relative to the shaft and supported surrounding the shaft. The annular magnet unit exerting an attracting force on the annular seal assembly to biasingly displace the annular magnet unit towards the annular seal. A bias member unit is also provided for non-magnetically biasing the annular magnet unit axially relative to the shaft towards the annular seal. Adjacent contacting surfaces between the annular seal and the annular magnet unit biasingly contact one another to form a sealing interface therebetween.

A tooling assembly for mounting a plurality of components, such as compressor blades, in a powder bed additive manufacturing machine to facilitate a repair process is provided. The tooling assembly includes component fixtures configured for receiving each of the compressor blades, a mounting plate for receiving the component fixtures, and a magnet assembly operably coupling the component fixtures to the mounting plate in a desired position and orientation to facilitate an improved printing process.

The proposed solution relates in particular to a method for assembling an engine assembly having a first engine component and a second engine component, wherein at least one fastening element is first of all arranged on an assembly aid, the at least one fastening element is arranged on the first engine component via the assembly aid and is held in an assembly position under the action of at least one magnetic element of the assembly aid, the at least one fastening element is fixed to the second engine component, and the assembly aid is removed again from the first engine component.

A guide vane assembly, with at least one guide vane row and a housing for the at least one guide vane row that extends along a circumferential direction about a central axis. The at least one guide vane row comprises multiple guide vanes that are respectively mounted at the housing in an adjustable manner by means of an adjusting appliance of the guide vane assembly. The adjusting appliance comprises at least one adjusting element for adjusting the guide vanes that is arranged at a radial distance to an outer side of the housing with respect to the central axis. A compensation device is provided, via which a radial distance of the adjusting element to the outer side of the housing is predetermined, and the different thermal expansions of the adjusting element and of the housing are at least partially compensated for the purpose of maintaining these distances.

A fan device includes a casing, a stator unit disposed inside the casing, a rotor unit disposed outside the casing corresponding to the stator unit, and a bearing support detachably connected to the casing. The rotor unit is isolated from the stator unit by the casing and includes a rotation shaft, a bearing, a fan wheel, and a rotor. The bearing support partially shields the rotor unit and supports the rotor unit in a manner that the bearing or the rotation shaft is fixed to the bearing support, so that the fan wheel is driven to rotate with respect to the bearing support as the rotor rotates relative to the stator unit, and the rotor unit and the bearing support can be removed together from the casing when the bearing support is removed from the casing.

Proposed is a method of controlling a portable air-flow guiding apparatus including adjusting at least one of an angle in a horizontal direction of a head unit including a sucking unit by a horizontal angle adjustment unit of the portable air-flow guiding apparatus and a height of the head unit by a height adjustment unit of the portable air-flow guiding apparatus according to a position of a heating source and a height of a cooking utensil.

A vane assembly includes a casing, vanes, and an actuator assembly. The vanes are arranged within the casing and are rotatably coupled to the casing for rotation relative thereto and configured to rotate about their pitch axes. The actuator assembly is arranged radially outward of the casing and includes an annular ring surrounding the casing and coupled to the vanes, a magnet arranged on the ring, and a stator spaced apart from the magnet. The ring is configured to rotate the vanes about their pitch axes in response to rotation of the ring about the central axis and the stator is configured to selectively rotate the magnet and ring about the central axis. The stator is configured to create a magnetic field which causes annular movement of the ring via interaction with the magnet.

A gas turbine engine comprising a casing, a bonding patch (10, 22) bonded to a surface of the casing, and a liner attached to the bonding patch. The bonding patch (10, 22) comprising a bonding region (12) configured to receive an adhesive for bonding the patch (10, 22) to a surface. A plurality of de-bonding elements (16) is configured to be movable relative to the bonding region (12) in response to an energizing signal.

A guide vane assembly, with at least one guide vane row and a housing for the at least one guide vane row that extends along a circumferential direction about a central axis. The at least one guide vane row comprises multiple guide vanes that are respectively mounted at the housing in an adjustable manner by means of an adjusting appliance of the guide vane assembly. The adjusting appliance comprises at least one adjusting element for adjusting the guide vanes that is arranged at a radial distance to an outer side of the housing with respect to the central axis. A compensation device is provided, via which a radial distance of the adjusting element to the outer side of the housing is predetermined, and the different thermal expansions of the adjusting element and of the housing are at least partially compensated for the purpose of maintaining these distances.
