Abstract: A structural media support is a system of Glass-Fiber Reinforced Polymer (G-FRP) members consisting of beams, columns and bracing together with an FRP grating grid for supporting filter media within a G-FRP odor control tank vessel. The odor control system receives odorous air flow into a plenum and via differential pressures within the system forces the air through a filter media for the degradation of the specific odorous compounds that accumulate on the media. Filtered air exits the media to a second plenum and is expelled from the tank vessel. The media support is a free-standing structural system within the tank vessel that is attached to the tank vessel floor through free-standing columns.

Abstract: A powder cyclone separator for use in a powder coating system is contemplated that is formed in two separate and separable sections. An upper section of the cyclone is mounted on a first frame and remains stationary. A lower section of the cyclone is mounted on a second frame that is movable laterally away from the first frame so that an operator has more ready access to clean interior surfaces of the upper section. Optionally, actuators may be provided to vertically raise and lower the cyclone lower section with respect to the cyclone upper section. Various optional alignment means are presented for aligning the cyclone upper and lower sections. Preferably, a control mechanism is mounted on the second frame which includes a switch that is manually operated by the user to raise and lower the lower section with respect to the upper section. This design allows an operator to see, and therefore verify, that virtually all internal surfaces of the cyclone have been effectively cleaned.

Abstract: A flow controller apparatus having few moving parts that may be inserted directly into a flow line to be responsive to flow pressure and maintain the flow rate constant. The flow controller has an internal bore that is a revolutional chamber having a maximum cross-sectional diameter at the inlet end and tapering toward a minimum cross-sectional area across a throat portion. A differential pressure plate supported axially movably in said chamber is spring biased toward the inlet end of the chamber, and is movable in response to upstream flow pressure to adjust the cross-sectional fluid flow area to maintain a constant flow rate. In addition, the use of such flow rate controller enables the construction of a portable type of fluid pressure and flow rate control apparatus to reduce pressure and flow rate from a high pressure, high volume liquid or gas source for supply to a low pressure, low volume output requirement.

The rear subassembly is connected to the central subassembly by coupling members and acts to cover the back side of the evacuating device incorporated in the central subassembly.

Abstract: A continuous, desublimination apparatus capable of operating at high flow rates. The apparatus works on the principle of reducing temperature of a vapor-gas mixture below the desublimination point. It has a heated jacket with inlets and outlets of gases in which a gas permeable wall is coaxially spaced. Said wall encloses a desublimination space with nozzles for atomizing an evaporable liquid and with a distributor of a vapor-gas mixture at the inlet. The space between said gas permeable wall and the inner jacket wall is divided into at least three vertically aligned sections, the volumes of which increase in the direction away from said inlet of the vapor-gas mixture. In operation, a vapor-gas mixture is cooled below the desublimination point by an atomized liquid. Simultaneous blowing of a secondary gas through said gas permeable wall protects the wall of said desublimination space from solid deposits.

Abstract: A module for providing a work area in which one or several people can perform tasks requiring ultra-high efficiency air filtration. The work area is bounded above by a filter module through which a vertical laminar flow of air occurs from one or more HEPA filters. From the perimeter of the module flows a curtain of air in an enclosing and substantially parallel relationship to the laminar flow air to extend the laminar air zone to the floor. The air curtain also passes through a HEPA filter prior to discharge. The angular direction of the air curtain is adjustably controlled by a unique nozzle structure so that when the air curtain contacts the floor turbulence is substantially eliminated and a sweeping action away from the work area is effected. Separate blower systems supply air for the laminar flow air and the enclosing air curtain at differential velocities.

The coating booth has a generally tubular configuration which when viewed in side elevation is generally oval but with a spiral curved bottom front wall which melds into a flat bottom surface extending toward an outlet at the bottom of the rear wall of the booth. On the rear of the booth there is a fixed fan module to which a removable filter module may be attached so as to interconnect the booth air outlet with the suction fan module. This construction facilitates quick color changes of the powdery material by maintaining a minimum deposit of powder on the interior of the booth and by enabling the filters to be interchanged without the necessity of first cleaning the filters or of interchanging individual filter media before restarting the booth with a new color.

A separate, high capacity air pump has its inlet connected to the cyclone's clean air outlet causing a flow of air through the unit for picking up gravel and dust through the flexible tube. For convenience the containers may be mounted on a truck, and both containers are unloaded through a common, sealable gate at the lower portion of the containers.

Abstract: Conductive filter elements are made by treating nonconductive fibrous materials such as inorganic or organic fibers with resins containing finely divided carbon. The treated fibers are then fabricated into filter elements which are electrically conductive throughout. Strands of roving or yarn which are nonconductive may be joined by twisting together with strands of conductive roving or yarn to give conductivity to the finished multiple strand. Conductive filter elements are also made from extruded fibers which are filled with carbonaceous material during extrusion. These elements permit grounding of static electrical potential which would otherwise accumulate in a nonconductive element. If desired, a controlled low potential direct or alternating electrical charge can be maintained on the filter element to enhance the separation of particles of opposite charge. Particulate filter media, such as that used in filter beds, may also be treated with carbon to form an electrically conductive filter mass.
