Abstract: A system for controlling airflow in a plenum, that comprises a worm gear and planetary gear that are removably coupled to a worm shaft and planetary shaft, respectively. The planetary shaft controls the movement of a damper between an open position permitting maximum airflow through the plenum, and a closed position restricting airflow through the plenum. A motor or gear-motor is positioned at the plenum for driving the worm shaft. The motor is controlled by a remotely located controller that includes a power supply for operating the motor and that has a display providing a continuous indication of the position of the damper between the open and closed positions. The controller is connected to the motor through a cable with a detachable electrical connection between the cable and the controller, such as a jack and plug. A wall plate for housing the electrical connection is mounted on a wall or other structure.

Abstract: A bracket for mounting a cable to a surface is presented. The bracket restricts lateral and longitudinal movement of a cable while enabling rotational movement. The bracket may be mounted to a first surface so that the cable may be inserted into a second surface. The bracket generally includes a mounting portion, first and second flanges, and an arm. To reduce longitudinal movement of the cable, the cable is inserted through the first flange and fixedly coupled to a ferrule, which is coupled between the second flange and the notch of the arm. To restrict lateral movement of the cable, a first flange includes a tab that when in a raised position, enables the cable to be inserted through the first flange. After which, the tab is lowered to reduce the size of the aperture. The bracket may also include a cap that is fixedly removable from the cable.

Alternatively, the movement of the damper is controlled by a drive shaft, which connects the motor or gear motor directly to the damper without intervening gearing.

Abstract: A gear system including a worm gear, planetary gear, worm coupling and planetary coupling is presented. The worm coupling couples a first shaft with the worm gear and includes a head and an elongated portion. The elongated portion is attached to the worm gear to serve as the worm gear's axle. The head includes an opening into which the worm shaft is inserted and may include additional bores into which set screws are inserted to removably attach the worm shaft to the worm coupling. The planetary coupling couples a second shaft with the planetary gear. The planetary coupling includes a bore into which the second shaft is inserted and may include additional bores into which set screws are inserted to removably attach the planetary shaft to the planetary coupling. By using multiple bores and set screws, the planetary coupling may accommodate a variety of planetary shafts.
