Trade literature Filing

Emission rates, modes, locations, and times must be described for each species studied. The emission work was done by Hydroscience, Incorporated (HI), of Knoxville, Tennessee. Emission characterization involved review of trade literature, files of the various states, EPA reports and data, and site visits and correspondence with staff of specific sources.

In the technical library the starting point of all searches is the file of index slips which the library has accumulated. This file includes references in periodicals, government publications, material put out by associations and societies, trade literature, books, literature searches previously made, and miscellaneous material. As in the case of patent searches, an earlier investigation brought up to date may take care of the request or some portion of it. Standard reference works in the field in question are then consulted. Abstract journals are covered next. This step in the search is of the greatest importance, as it serves as a key to the periodical literature. An abstract is not regarded as a substitute for the article abstracted in all but a brief preliminary examination the original reference is read if at all possible. 

Most people read or note technical trade literature as it is received. Some then discard it, whereas others cram their own desks or files with those items of interest to them. Some material is routed to associates, in which case it may readily get lost along the line, depending upon the diligence with which these people read it and send it along. Fre-... 

The type of filing system employed is important in determining the availability of information to the searcher. Some companies file ever3rthing under the company name and may segregate these into categories such as suppliers and customers. Frequently the technical data sheet, bulletin, or other item of trade literature is not accessible to the searcher who does not know the name of the company manufacturing the product or providing the service in question. 

It is important for companies to keep the patent system in mind, whether or not they choose to seek patents for their own products. When technical personnel create useful products or processes that seem to them to be significant advances on the prior art, the assistance of patent counsel very often becomes useful. First, companies need to determine whether use or sale of these new processes or products might infringe someone else s patent. This may involve a search of the relevant records of the United States Patent and Trademark Office (and of the patent offices of any foreign countries where the products may be used or marketed). Second, if the product seems to technical personnel to be novel and significant of the art, companies may want to consider whether to apply for a patent. In such a situation, a search should be made at the Patent and Trademark Office to determine whether the invention seems likely to be patentable. How extensive a search should be before a patent application is filed, as well as the decision whether to seek a patent at all, may depend upon how valuable the invention seems. For a very important item, patent lawyers may also conduct searches of the relevant trade literature to see whether the invention has been anticipated but not patented. Some companies monitor the... 

National Museum of History and Technology. 1978. Guide to Manuscript Collections in the National Museum of History and Technology. Washington, D.C. Smithsonian Institution Press. Volume 3 of the series Archives and Special Collections of the Smithsonian Institution. The Museum of History and Technology holds important archival collections. One can find in their collections both fundamental source materials and illustrative material not found elsewhere. Most of the entries in this guide concern personal papers, business records, or document files however, one can also find graphic material, trade literature, and information and reference files. 

Finally, new developments in zeolite catalyst and adsorbent manufacture will be outlined in the form of a survey of recent open and patent literature. Patents are extensively cited as reference materials for this chapter however no effort is made to identify specific manufacturing techniques actually used by any particular company to manufacture zeolites or any catalytic or adsorbent products. This is because there is no way to determine whether manufacturing patents are practiced as is or whether further refinements have been accomplished subsequent to the filing of the patents that may be held by specific companies as trade secrets. 

Process spectroscopy is, almost by definition, done to measure and control an industrial process. Almost all of the work is driven by business needs, such as improving profits or product quality. In competitive business environments, firms preserve every advantage possible by protecting valuable measurement systems as trade secrets. Thus, firms are often reluctant to reveal process spectroscopy applications, whether successful or not. Notable exceptions to this include the desire for positive publicity around improved safety or to direct the regulatory environment. Often, companies will patent the work and will not publish in a scientific journal until after the patent is filed, if ever. Many applications, such as the classic titanium oxide-monitoring paper, are revealed only years after implementation. As a consequence, the current state of the art in the literature is quite likely far out of date. 

An efficient approach to this problem is to separate the house organs worthy of consideration into those equivalent to journals and those equivalent to trade publications in terms of content. The house organs considered equivalent to journals then should be given the necessary time and attention. They should be included with the journals in evaluation of articles for the internal literature abstracting service and for the file of articles of importance to a company s products, processes, and fields of interest. Retention schedules must be established in much the same manner as for journals. A few house organs will be bound. The important articles in those not bound should, of course, be clipped and retained in some accessible form. House organs adjudged to be equivalent to trade publications should be so treated. 

The searcher for technical trade information may have available files and library shelves as a starting point. However, frequently his problem involves some new type of information which is unlikely to be on hand, or the data on hand may be incomplete. In these instances the first objective is to learn the identity and source of literature which should contain the desired information. 

Indexes to German Industrial Reports. The major portion of the German chemical industry was controlled by I. G. Farbenindustrie. Not only did FIAT members prepare indexes to some of the I. G. Farben material copied (18-21), but FIAT also copied I. G. Farbenindustrie s own extensive card index files, which include structure, trade name literature, and LG. Farbenindustrie report references, and cover such subjects as dyes, plastics, and organic chemicals. A list which includes the 45 PB reports comprising this series, and their prices, is available from OTS (17). 

The Registry Handbook - Common Names provides a simple method of determining, which chemical substance is meant by a trade or trivial name or vice versa and which other names are known for a certain substance. This is especially important for literature searches in which no CAS Registry Numbers can be used, only substance names. In many cases it can save an expensive online search in the Registry File.
