Abstract: A mounting system with a mount member that is configured to be recessed into the wall. The mount member defines a first mount, which is configured to be abutted against a structural member of the wall, a second mount, which is parallel to the first mount, and a pair of first legs that are coupled to at least one of the first and second mounts and which space the first and second mounts apart from one another. A plurality of mounting holes are formed through the first mount and a plurality of clearance holes are formed through the second mount. Each of the clearance holes is disposed in-line with an associated one of the mounting holes. A slot is formed through the second mount. The slot is disposed between the first legs and extends through a side of the second mount.

Abstract: A two-piece magnet retention ring for an eddy-current fan drive mechanism.

Abstract: Pneumatic fan drive assembly with improved capacity, longevity and heat control. The output member is positioned radially internally of the output member. The friction mechanism has longer movement (moment) arms and torque. The friction engagement has an increased friction surface arm. A portion of the heat generated by the friction mechanism is evacuated to the atmosphere rather than being completely internalized in the assembly. The friction material for the friction lining alternatively can be formed of a plasma spray.
