Abstract: Catalytic materials are used as a part of or in association with heat exchangers such as automotive radiators and air conditioning condensers. The catalytic material involves a metal substrate with a porous anodic oxide coating and metallic nodules which are electrodeposited in the pores and extend above the surface of the anodic oxide coating. The nodules are either formed of the catalytic metal or formed of other metals and then coated with the catalyst metal. The catalytic stock material is then formed into heat exchanger fins and mounted on the heat exchanger tubes. In the alternative, the catalytic stock material may be formed into a separate catalytic structure which is then mounted in an air flow stream and preferably in air-flow relationship to the heat exchanger.

Abstract: A plant system is preferably made of plastic and even more preferably made of clear acrylic structural members. Such acrylic members take on the color of the surrounding plants and "blend" into the background created by the plants. The acrylic members have abbreviated length attachment members which extend from opposite sides of the structural members, and the attachment members have a differing diameter. The outermost portion has a smaller diameter which facilitates the initial overfitting of a plastic strap having a plurality of apertures. The strap is moved to surround the plant portion to be supported and the other end's aperture is also fitted over the attachment member. The resulting loop extends widely around the plant portion giving it adequate room for growth and further extension through the loop. The system, including the structural members and attachment members can be interconnected using a series of connectors to form a trellis or other support shape.
