Some embodiments of a fan clutch system for use in a vehicle can provide efficient access to one or more components for inspection and service even after the fan clutch system is installed in the vehicle. In particular embodiments, the fan clutch system can include a fan clutch device and a coil retainer assembly that are removably mounted to a right-angle gear box assembly in a manner that permits a technician to accessing at least one component for inspection, repair, or replacement. The coil retainer assembly may at least partially house an electromagnetic coil for selective activation. The system may further include a fan clutch device removably mounted to the drive member of the gear box assembly.

A shredding device for shredding materials is provided, the shredding device having: a housing, a rotor in the housing, a pusher element which is pivotable about an axis, so that it pushes the material to be shredded towards the rotor, and a service hatch which is mounted on the housing and configured in such a manner that in an open state it exposes a first opening in the housing with access to a rotor and a second opening in the housing with access to the underside of the pusher element when the latter is pivoted upwardly.

Method for replacing, inspecting, and/or repairing components in front bearing region of gas turbine, the gas turbine having at least one fan module, housing, low-pressure system, and high-pressure system, the low-pressure system having low-pressure compressor, low-pressure turbine, connecting shaft, stub shaft, and an N1 shaft connected to the low-pressure compressor via the stub shaft and the connecting shaft, the connecting shaft supported in the housing via first bearing unit, and the stub shaft supported in the housing via second bearing unit, the method including dismounting the fan module, fixing the N1 shaft in an axial direction relative to the housing using fixing device, and dismounting the stub shaft using guide device, the orientation of which relative to the gas turbine in at least one spatial direction is determined by a component of the remaining gas turbine, this taking place after fixing the N1 shaft and after dismounting the fan module.

An exhaust-side journal bearing for supporting a gas turbine rotor is disposed inside a bearing box. The bearing box is supported by a strut which extends inward from an exhaust casing, and a seal ring having an annular inner peripheral end is disposed on the bearing box. Executed during a maintenance work are: a bearing adjustment step of displacing a bearing surface of the journal bearing relative to the bearing box in a perpendicular direction perpendicular to the axial direction; and a seal ring adjustment step of displacing the inner peripheral end of the seal ring relative to the bearing box in accordance with the direction of displacement and the amount of displacement of the bearing surface.

The invention resides in an apparatus for treatment of a substance. The apparatus has a substance tube for enabling a substance to be treated to pass in to the substance tube via the substance-inlet and out of the substance tube through the substance-outlet. The apparatus also has a cleaning chamber, wherein the substance tube is configured in fluid communication with the cleaning chamber to enable a substance to diffuse the permeable membrane between the substance tube and the cleaning chamber such that a substance can be substantially cleaned by a cleaner, the substance comprising blood or plasma and the cleaner comprising a cell culture. The substance tube is removably connectable with the cleaning chamber for inter-changeability or serviceability. The apparatus can further comprise a support compartment configured to connect to, or enclosing, the cleaning chamber, which functions to carry a fluid to substantially maintain the functionality of the cleaner.

According to the disclosed embodiments, an illustrative apparatus that is configured to attach to a viewport of a container comprises a first plate having a first aperture and an attached second plate having a second aperture substantially aligned to the first aperture. The first and second plates, when attached, define a cavity from an outer edge of the first and second plates to the substantially aligned apertures. A window containment arm is pivotally affixed to at least the first plate and configured to substantially fit and pivot into and out of the cavity, and a window contained within the window containment arm is positioned such that the window substantially aligns with the first and second apertures when the window containment arm is fully pivoted into the cavity, and such that the window is accessibly located outside of the cavity when the window containment arm is pivoted out of the cavity.

A method of servicing a gas turbine engine is disclosed. According to the method, a component including a titanium alloy is removed from the gas turbine engine after operating the gas turbine engine with the component in service. The removed component is subjected to heat treatment, and the heat-treated component is re-installed into the gas turbine engine or installed into a different gas turbine engine.

A firearm including a receiver, a barrel, a breech bolt assembly, and a trigger assembly. The bolt assembly has a bolt including a body portion, a lug portion, and a firing pin bore. The lug portion includes outward extending lugs, a cartridge recess, and an off-center hole. The bolt assembly also includes an extractor and an ejector pin. At least some of the lugs on the lug portion of the bolt have a tapering outer face so that a rearward face of the respective lug is taller than a forward face of the respective lug. In another aspect, at least some of the lugs on the lug portion of the bolt have tapering side faces so that a rearward face of the respective lug is wider than a forward face of the respective lug.
