Abstract: A system and related method for separating floating and nonfloating particulate and entrained, suspended, and/or dissolved contaminants from a fluid. The system includes a tank with a lower chamber spaced from an outlet or upper chamber by a confinement deck. The deck includes one or more sockets for receiving one or more filter units for fluid treatment. In addition, the lower chamber of the tank acts as a pretreatment sump to remove floating and nonfloating particulates, thereby reducing the load on the filter units. The filter units are configured for radial and/or upward flow of the fluid from the lower chamber. The filter units may include one or more filter media through which the fluid pass prior to exiting the tank. The filter units include a removable screening retainer for retaining the filter media and/or to screen relatively large contaminants. The filter unit may be removed for ease of tank maintenance and replacement of filter media.

Abstract: An adjustable support for a display terminal is provided which comprises a novel moulded base element having a pair of concave tracks in the top and an annular recess in the bottom. The concave tracks in the top of the base are adapted to receive and support a moulded cradle element which serves as a housing for the CRT display. The annular recess in the bottom of the base receives an annular support ring which is adapted to support the base and the cradle. The three moulded elements are designed to fit together and maintain contact with each other by gravity so as to provide a low cost accurate adjustable support.
