Abstract: The exhaust gas diffuser and filter system for a pneumatic nail gun provides for the diffusion and filtering of exhaust gas, which is typically pressurized air, generated by the pneumatic nail gun during usage thereof. The system includes a diffuser plate adapted for covering the exhaust ports of the pneumatic nail gun, and further includes a bag formed from an air permeable material, allowing for further diffusion and filtering of the exhaust gas. The diffuser plate has a plurality of fluid passages formed therethrough, and is adapted for releasable mounting on the exhaust portion of the pneumatic nail gun. The plurality of fluid passages diffuses the exhaust gas produced by the pneumatic nail gun during use. The bag provides for further muffling of exhaust noise and diffusion of the exhaust gas, and further provides filtering thereof.

Abstract: Toxic waste materials are encapsulated by the method wherein the waste material in liquid or finely divided solid form is uniformly dispersed in a vinyl ester resin or an unsaturated polyester and the resin cured under conditions that the exotherm does not rise above the temperature at which the integrity of the encapsulating material is destroyed.
