Abstract: A clothes dryer including a control circuit for controlling the operation of the dryer and for preventing the dryer from operating unless the dryer lint screen is cleaned periodically. The control circuit disables the dryer either after every drying cycle, after a predetermined amount of time, or after the lint filter becomes clogged. The control circuit re-enables the dryer after the lint screen has been removed from the lint screen compartment and cleaned.

Abstract: A system for dividing rotary power to two or more output shafts includes planetary cluster cages that are associated with the output shafts and which are interconnected by a hydraulic circuit. In instances where the output shafts rotate at speeds different from one another, a portion of the power from the source is directed through the hydraulic circuit to cause rotation of spiders carrying planetary gears within the cluster cages coupling the output shafts to a primary driveshaft. The power division system is modular in nature in that the hydro-planetary cluster cages and associated drive axles can be easily added or deleted as desired.
