299 | GERM WARFARE AGENTS DESTROYED |
300 | PROCESSES FOR MAKING HARMFUL CHEMICAL SUBSTANCES HARMLESS, OR LESS HARMFUL, BY EFFECTING A CHEMICAL CHANGE IN THE SUBSTANCES (EPO/ JPO) |
Note: When classifying in subclasses 300-321, classification is also made in subclasses 400-415 to identify the hazardous substance. | ||
301 | By subjecting to electric or wave energy or particle or ionizing radiation (EPO/ JPO) |
302 | Electrochemical processes, e.g., electrodialysis (EPO/JPO) |
304 | Sonic energy (EPO/JPO) |
305 | Particle radiation, e.g., electron beam radiation (EPO/JPO) |
306 | Electromagnetic radiation, e.g., laser (EPO/ JPO) |
307 | Gamma rays (about 0.003nm-0.03nm) (EPO/JPO) |
308 | X-rays (about 0.03mn-3nm) (EPO/JPO) |
309 | Ultraviolet radiations (about 3nm-400nm) (EPO/JPO) |
310 | Microwave radiations (about 0.3cm-30cm) (EPO/JPO) |
311 | Plasma (EPO/JPO) |
312 | By hydropyrolysis or destructive steam gasification, e.g., using water and heat or supercritical water, to effect chemical change (EPO/JPO) |
313 | By reacting with chemical agents (EPO/JPO) |
314 | By treatment in molten chemical reagent, e.g., salts or metals (EPO/JPO) |
315 | By chemical fixing the harmful substance, e.g., by chelation or complexation (EPO/JPO) |
316 | Dehalogenation using reactive chemical agents able to degrade (EPO/JPO) |
317 | By hydrolysis (EPO/JPO) |
318 | Detoxification by using acid or alkaline reagents (EPO/JPO) |
319 | By reduction, e.g., hydrogenation (EPO/JPO) |
320 | By oxidation; by combustion (EPO/JPO) |
321 | By heating to effect chemical change. e.g., pyrolysis (EPO/JPO) |
400 | Harmful chemical substances made harmless, or less harmful, by effecting chemical change (EPO/JPO) |
Note: Subclasses 401 through 404 form part of a multiple aspect schedule. Documents classified in one of these subclasses are normally also classified in subclasses 405 through 415 to identify the hazardous material. | ||
