Abstract: A multi-layer article includes a fluoropolymer layer and a substrate which are joined permanently through a multi-step cross-linking technique.

Abstract: The present invention relates generally to modeling of aeration systems. More particularly, the present invention relates to an automated modeling system that acquires data from entries made into a dialog box. The automated modeling system then generates a full CAD drawing denoting the precise locations of aeration system components in both plan and section view, such as diffusers, support stands, expansion joints, manifold pipes, header pipes, etc., and furthermore generates a materials take-off table.

Abstract: The Quick Connect Diffuser Assembly of the present invention includes a special saddle in fluid communication with an air distribution header pipe and a diffuser body connected to the special saddle. The saddle is connected to the air distribution header pipe with a two interlocking sections joined on one side with a hinge, and on the other with flanges. The flanges are connected with a wedge piece. The diffuser connects to the upper saddle section with a bayonet type Quick connection. Gas is forced from the air distribution header pipe through an orifice hole in the pipe, then through the saddle and exits the diffuser body through a diffusion membrane. The membrane forms the gas into fine bubbles that aerate liquid contained in a basin. A single saddle assembly is adaptable to mount on either US or Metric pipe, which have different outside diameters, by changing gaskets and an O-ring.
