Abstract: An ozonated water dispenser allows a user to kill bacteria and microbiological organisms on their hands or other objects. The dispenser includes a reservoir, a pump, and an ozonated water delivery means downstream from the pump to dispense pressurized ozonated water in a fine mist. The delivery means includes a mister and a control valve, such as a solenoid, to restrict water flow in a water line to build up water pressure between the pump and the control valve to overcome the mister's cracking pressure.

Abstract: A system and process for dispensing a liquid agrochemical such as ammonia into a field is disclosed. The ammonia is placed in a vessel under sufficient pressure to maintain a substantial portion of the ammonia in a liquid form. From the pressurized vessel, the ammonia is fed to a distribution manifold where it is ultimately injected into a soil through a plurality of dispensing tubes.
