  • Patent number: 6658902
    Abstract: A dynamic balancer for an automatic washer includes an annular hollow first chamber. A first fluid is held within the first chamber and only partly fills the first chamber. An annular hollow second chamber is disposed adjacent to the first chamber and includes a plurality of objects disposed therein which are movable along the chamber. A second fluid is also held in the second chamber and, in combination with the solid bodies, only partly fills the second chamber. The first fluid in the first chamber produces a first balancing characteristic of the dynamic balancer. The movable objects within the second chamber produce a second balancing characteristic of the dynamic balancer. The second fluid held in the second chamber also produces a third balancing characteristic of the dynamic balancer.

  • Patent number: 5809828
    Abstract: An airflow test device designed to be used in a clothes dryer. The device includes a retainer which is mounted to an outlet grate of the dryer drum. A vent card is removably supported a predetermined distance from the outlet grate by a support finger extending from the retainer. The vent card is supported in such a manner that a predetermined rate of airflow through the outlet grate during dryer operation moves the vent card toward the outlet grate. Movement of the vent card toward the outlet grate and off the support finger during clothes dryer operation signals that an adequate rate of airflow is passing through the outlet grate.
