Abstract: Methods and mechanisms for shaking containers are disclosed. The shaking motion can be made to vary in a dynamic fashion so that the different components within the container are not made to separate, as if subjected to the processing of a centrifuge. Such dynamic motion can appear to be random. A cantilevered base plate or other type of based place can be coupled to a base. A motor can be coupled to the base plate and configured to rotate a generally vertical shaft. A cam or other type of wheel can be coupled to the shaft and configured to eccentrically rotate about the shaft, wherein the wheel is configured to rotate within a bearing. A container base is coupled to the bearing such that the container base is configured to translate or otherwise move is general accordance with the eccentric rotation of the cam. The container base can be configured to tilt based at least in part on the translation of the container base.

Abstract: An air filtration system includable in and for HVAC equipment includes one or more intense field dielectric filter units and a field charging unit retained in a support structure or cabinet by a removable door which includes control circuitry and contactors engageable with corresponding contact members on a filter unit and the field charging unit for supplying high voltage DC potential to the respective units. Each filter unit includes a filter core comprising a stacked array of filter elements formed of dielectric sheets interconnected by elongated spaced apart ribs forming flow passages. The field charging unit and the filter units are removable from the support or cabinet for cleaning or replacement by opening or removing the door. An interlock switch and a field shorting mechanism are actuated during servicing or replacement of the system components.

Abstract: A centrifugal blower for a furnace, heat pump, or other type of air handling unit includes a heat-generating blower housing that heats the airflow as the air passes through the blower housing. In some cases, the housing is made of a thermosetting resin impregnated with graphite or co-molded with a graphite cloth. Heat is generated within the housing wall by applying voltage across the housing.

Abstract: Apparatus for disinfecting water flowing through a water system including a water pipe includes a water bypass line having an inlet and outlet communicating with the water pipe. A wye connector is positioned in the water bypass line and includes a closed interior chamber which receives water from the water bypass line and promotes water turbulence. Electrode elements project into the chamber which are electrically connected to a power supply which imparts electrical energy to the electrode elements and causes the release of ions from the electrode elements into the turbulent water within the wye chamber.
