A fabric delivers active ingredients to a surface when the fabric includes a moist-vapor porous combination of fabric materials, and the fabric comprises at least 0.5% by total weight of at least one layer of the fabric of a superabsorbent polymer fiber. The superabsorbent polymer fiber contains an absorbed aqueous reservoir of an aqueous solution carrying the active ingredients. The superabsorbent fiber has a coating on its surface of an aqueous penetrable layer through which a liquid in the absorbed aqueous reservoir can migrate or flow, carrying the active ingredients onto an exposed surface of the superabsorbent polymer fiber, so that the active ingredients on the surface of the superabsorbent polymer can react or interact with an environment in contact with the active ingredients on the superabsorbent polymer fiber surface.

A propeller shaft for a vehicle in which a tube yoke is connected to a main tube via an adapter and tapered splines are formed at the contact regions between a tube yoke and the main tube to transmit the power output from a transmission to a rear wheel. The tube yoke and the main tube are displaced relative to each other at the tapered splines to break the adapter. The tube yoke and the main tube are thus separated from each other by virtue of the breakage of the adapter.

A propeller shaft for a vehicle is provided in which a tube yoke is connected to a main tube via an adapter and tapered splines are formed at the contact regions between a tube yoke and the main tube to transmit the power output from a transmission to a rear wheel. The tube yoke and the main tube are displaced relative to each other at the tapered splines to break the adapter. The tube yoke and the main tube are thus separated from each other by virtue of the breakage of the adapter to efficiently absorb impact energy.

A generator arrangement includes a housing with a mounting feature, a main generator with an outboard shaft arranged within the housing and axially offset from the mounting feature along a rotation axis, and a permanent magnet generator. The permanent magnet generator has an inboard shaft arranged within the housing between the main generator and the mounting feature. The outboard shaft is coupled to the inboard shaft to provide rotation to the main generator through the permanent magnet generator. Accessory gearboxes and methods of generating electrical power are also described.

An assembly including an accessory gearbox mechanically connected to an electricity generator having a support shaft that includes a calibrated breakable section designed to disconnect the electricity generator physically from the accessory gearbox when an incident is detected on the electricity generator, the protection device including an unlocking mechanism provided with a lock that, under the action of an external control unit, releases a cutting tool so as to cut said calibrated breakable section.

A coupler that separates a unitary valve stem into two separate but coupled sections to isolates the thrust load from the torque load.

An air turbine starter for starting an engine, comprising a housing defining an inlet, an outlet, and a flow path extending between the inlet and the outlet for communicating a flow of gas there through. A turbine member is journaled within the housing and disposed within the flow path for rotatably extracting mechanical power from the flow of gas and a gear train is drivingly coupled with the turbine member. A drive shaft is operably coupled with the gear train, and a decoupler is selectively coupled to the drive shaft for decoupling the air turbine starter from the engine.
