Abstract: An antifouling barrier comprising a silicon bronze alloy, the silicon bronze alloy comprising about 0.5% to about 3.8% silicon (wt/wt alloy) and greater than about 90% copper (wt/wt alloy). In some embodiments, the silicon bronze alloy additionally comprises from about 0.05% to about 1.3% manganese (wt/wt alloy). The antifouling barrier may be a welded wire mesh, screen, chain-link, chain-mail, grid, weave, perforated sheet, or chicken wire. Methods of reducing the growth of an organism on an animal enclosure, comprising contacting at least a portion of the animal enclosure with an antifouling barrier comprising a silicon bronze alloy comprising about 0.5% to about 3.8% silicon (wt/wt alloy) and greater than about 90% copper (wt/wt alloy).

Abstract: The present invention provides a temperature control system for an aircraft ventilation system that couples with existing aircraft upstream ventilation system architecture and downstream ventilation system architecture. The temperature control system includes an air duct arranged to receive a volume of ventilation air from the upstream ventilation system architecture and transfer the volume of air to the downstream ventilation system architecture. A heater is arranged to heat the ventilation air. A controller is arranged to control the heater responsive to a comparison of the actual temperature of the ventilation air to a desired range of temperatures. The controller maintains the actual ventilation air temperature within the predetermined range of temperatures such that formation of ice is minimized in the aircraft ventilation system. An exhaust shutoff valve between the air distribution system and the lavatory/galley ventilation system provides for ventilation in the event smoke is detected.
