Abstract: Apparatus and methods are disclosed for using an ultraviolet laser system to decompose selected chemical substances in water. More particularly, this invention provides methods and apparatus whereby various environmental pollutants in water are rapidly decomposed to very low concentrations, consistent with environmental discharge regulations, use requirements, and/or applicable health standards, by means of exposure to ultraviolet laser irradiation (10, 20), either with or without one or more catalysts and/or other chemical additives to facilitate or enhance the decomposition process.

Abstract: A distributed data processing system and method for intertransmission of information signals between a central processor and one or more remote computer controlled terminals which includes inputting information signals to the processor and remote terminals for generation of information data at the processor and remote terminals respectively, addressing each of the remote terminals by generation of unique address data at the processor, directing a function of an addressed remote terminal by generation of identifiable function data at the processor and informing the processor of the status of the addressed remote terminal by generation of identifiable status data at the terminal in response thereto, developing complementary data in conjunction with the generation of address, function, status and information data, transmitting the address, function and status data with the complementary data thereof between the processor and remote terminals, transferring the information data and complementary data thereof betwe
