Abstract: A housing having a front angularly inclined portion, and a central platform portion for supporting from below, a video monitor. A rear portion includes sockets for connecting electrically to electrical equipment associated with the monitor for power control purposes. Actuator members are mounted reciprocatively in an angular front face of the front portion to switch power to the video monitor and a computer upon which the housing and video monitor are stacked.

Abstract: A static diffuser for use within the water tank of an ozonator system. The diffuser comprises a depending water pipe into which water is fed under pressure by an external pump. The lower end of the pipe flares outward and has an internal fixed cone which combines with the flared end of the pipe to provide an annular laterally directed water discharge. The annular discharge includes angularly directed vanes to enhance the water discharge and assist in forming a high velocity outwardly directed circular sheet of water. The pipe is surrounded, in spaced relation, by a shroud through which the ozone is introduced. The shroud is provided with an annular slot outward of the pipe discharge, the shape of the shroud at the slot forming a modified 360.degree. circular venturi whereby the discharging high velocity sheet of water creates a negative pressure drawing the ozone therewith into the surrounding body of water for a ozonation thereof.

Abstract: A three phase power ozonator system in which the head of an ozonator cell containing multiple cylindrical type elements is tri-partitioned to define three sectors in the cell each of which contains a portion of the total number of cylindrical type dielectric elements. The partitions are made of insulating material such as polyvinyl chloride. Each sector is distinct and each sector is adapted to be operated with single phase electrical power. As a result the ozonator cell as a whole is able to operate using three phase electrical power. This arrangement allows for the operation of the ozonator cell in a system having any number of other three phase electrically operated components of equal or smaller electrical load than the ozonator cell in such a way that a balanced electrical load is maintained throughout the system.
