Patent classification codes are another subject-search parameter available in most patent databases. IPC codes are usually present and U.S. codes exist in a number of files in the case of Japan Patent Information Organization (JAPIO), Japanese codes too are available. It is possible to mimic a hand search by limiting operations to references falling within one class or group of classes. Although such strategies can in some instances be justified, it is usually wiser to treat class codes as just one of the various subject parameters that make up a search strategy. 

Since the second edition OFTHE Chemistry of Organic Fluorine Compounds Milos Hudhcky continued screening Chemical Abstracts to keep up with fluorine chem istry Some 15 000-20,000 clippings accumulated in the file cabinets in his office After his retirement, he was almost at the verge of discarding this voluminous material when it occurred to him that it could be used as a first-tier literature search for updating the book...

Two recent reviews of hydrocarbon radical enthalpies of formation are J. Berkowitz, G. B. Ellison and D. Gutman, J. Phys. Chem., 98, 1744 (1994) and W. Tsang, in Energetics of Organic Free Radicals [Vol. 4 in file SEARCH Series (Eds. J. A. Martinho Simoes, A. Greenberg and J. F. Liebman), Blackie Academic Professional, an imprint of Chapman Hall, London, in press]. The enthalpies of formation of hydrocarbyl radicals is still a subject of some dispute. Admitting our prejudices, file values chosen in file current study are those recommended by the latter reference. 

I. X-Ray Literature Search System. The data base used in the X-ray crystallographic search system described in (c) above possesses complete literature references to all entries in the file [4], This information has been made the basis of a system for searching by author, title word, etc, the literature pertaining to the X-ray diffraction study of organic molecules. 

In searching for chemical methods of destroying organic pollutants, chemists tend to look to oxidative methods, since the preferred end product is usually C02, but, as discussed below, special methods are usually necessary to bring about oxidation to acceptable products. In 1995, however, it was shown that elemental (zero-valent) metals such as ordinary iron filings can be effective in the reductive conversion of halocarbon pollutants such as trichloroethene in wastewater to innocuous hydrocarbons over a few days14 ... 

Manual search identification data for various crystalline energetic materials, drawn from the above file and other sources are presented in Tables 1 (inorganic) and 2 (organic). The strongest reflections (the most intense on film or the highest in amplitude on a recorder chart) of the...
