Abstract: The invention is a system for mixing first and second components of a coating to be applied to a surface in a precise ratio. The system includes a mixer within which the first and second components are combined to form a mixture. A first supply transmits the first component at a first flow rate to the mixer, the first supply producing a first flow rate signal representative of the first flow rate. A second supply which transmits the second component at a second flow rate to the mixer, the second supply producing a second flow rate signal representative of the second flow rate. First and second flow control valves are connected between the first and second supplies, respectively, and the mixer for controlling the first and second flow rates from the first and supplies in accordance with a timed duty cycle.

Abstract: An air pollution control apparatus usable for capturing airborne pollutants present in a relatively confined environment. The apparatus is a portable airborne-pollutant capturing device movable to a site of pollutant origin and having at least one airborne-pollutant collector member, a vacuum system, and a filter system. The filter system can include one filter or more than one identical or different filters chosen for enhanced filtration capabilities in relation to pollutants present. Preferably, more than one type of filter can be accommodated simultaneously to thereby capture multiple pollutants. Fugitive particulate is captured by positioning the airborne-pollutant collector member proximate the activity causing pollution, and operating the collector member simultaneously with the polluting activity to thereby cause particulate to be captured by the filter system.

Abstract: An air pollution control apparatus for capturing airborne pollutants present in a relatively confined environment. The apparatus includes a portable airborne-pollutant capturing device movable to a site of pollutant origin and having at least one airborne-pollutant collector member which can be non-limitedly exemplified as a collection hood positionable at the site of pollution for pollutant collection or a painting tray upon which items can be placed and painted and beneath which resultant pollutant can be collected. A vacuum system is present within the capturing device and is in communication with the one or more collector members to draw airborne pollutants into the capturing device through the pollutant collector member. Actual capture of pollutants is accomplished by a filter system within the capturing device. The filter system can include one filter or more than one identical or different filters chosen for enhanced filtration capabilities in relation to pollutants present.

Abstract: In accordance with the present invention, there is provided a high volume, low pressure paint spray gun connectable to a paint source, an atomization air source and a shaping air source. The paint spray gun is provided with a spray gun body which is in fluid communication with the paint source, the atomization air source for atomizing paint and the shaping air source for shaping paint spray patterns. The spray gun is further provided with a nozzle which defines a paint atomizing zone for discharging atomized paint and a paint spray pattern shaping zone shaping atomized paint spray patterns. The spray gun is further provided with a paint hose, atomization air hose, and shaping air hose each having an inlet end which is connected to the spray gun body and a discharge end which is connected to the nozzle. The spray gun is further provided with a bendable, shape-retaining paint conduit having an inlet port which is connectable to the spray gun body and an outlet port which is connectable to the nozzle.
