Abstract: The present invention provides a system and method for the disinfection of irrigation water. Irrigation water is exposed to ozone, which disinfects and flocculates the water for improved removal of bacterial contamination. One or more ozone generators produce ozone gas that is injected into the flow of irrigation water at one or more points in an irrigation water treatment system. The ozone may be hyper concentrated, and the mixing of ozone and water may be optimized so that the maximum amount of water is exposed to a concentration of ozone that is high enough to disinfect the water over the period of contact. Ozonated water is then delivered to farm fields. No harmful residues remain in the water or soil after treatment.

Abstract: An anti-torpedo torpedo having laser homing head, the torpedo being launched from a parent vessel or platform which itself houses the expensive to replace, the bulky, or the high power consuming parts of the laser, said parts being optically connected to an optical projector in the homing head in the torpedo itself and to any parts of the laser not housed in the parent vessel.

Abstract: A steering wheel mounted air bag cover door (10) includes a horn switch (20) disposed on its outside surface (16) for actuating a vehicle horn (40) in response to the application of a predetermined horn actuating force to the cover door. The horn switch (20) is spaced apart laterally from the tear seam (18) on the cover door (10). A cover band (22) extends over and conceals the horn switch (20), the cover band also being spaced apart laterally from the tear seam (18). The cover band (22) includes a removable attachment feature (26) whereby the cover band may be removed easily from the cover door (10) to replace the horn switch (20). An adjustment feature (28) enables one to adjust the distance between the cover band (22) and the cover door (10) to prevent pinching of the horn switch (20).
