Classifications technology

In the past several years, tire pyrolysis has not looked profitable, primarily because of the technical problems of upgrading the char. The next few years should determine whether ATR s new char classification technology can help to overcome these problems. 

Particle classification technologies include impoundment basins, hydraulic classifiers, hydrocyclones, grizzlies, and screens. Following is a descrqition of these technologies. Applications, limitations, and relative costs for the first three listed particle classification technologies are identified in Table 2. 

Currently, there are three classifications of grown-in microdefects experimental classification, technological classification and physical classification. 

Table 3. Classification of High Performance Fibers and High Technology Textiles by Property...

Another way to classify high performance fibers and high technology textile materials or products is by types of appHcations. A scheme of 10 main categories has been adopted (Table 4) and is similar to several classification schemes previously reported (28). 

Battery breaking technologies use wet classification to separate the components of cmshed batteries. Before cmshing, the sulfuric acid is drained from the batteries. The sulfuric acid is collected and stored for use at a later stage in the process, or it may be upgraded by a solvent extraction process for reuse in battery acid. 

In the words of RSPA, the changes to the regulations will (/) simplify and reduce the volume of the HMR, 2) enhance safety through better classification and packaging, (3) promote flexibiUty and technological innovation in packaging, (4) reduce the need for exemptions from the HMR, and (5) facihtate international commerce (3). 

These contain most of the dyes and intermediates on chemistry and technology, but in general are more difficult to access than books and journals. Dyes are classified under Section E2 of Derwents Wodd Patents Index Classification. 

A useful classification of sensitizing dyes is the one adopted to describe patents in image technology. In Table 1, the Image Technology Patent Information System (ITPAIS), dye classes and representative patent citations from the ITPAIS file are Hsted as a function of significant dye class. From these citations it is clear that preferred sensitizers for silver haUdes are polymethine dyes (cyanine, merocyanine, etc), whereas other semiconductors have more evenly distributed citations. Zinc oxide, for example, is frequendy sensitized by xanthene dyes (qv) or triarylmethane dyes (see Triphenylmethane and related dyes) as well as cyanines and merocyanines (see Cyanine dyes).

The resultant four-character diamond bit classification code was formally presented to the lADC Drilling Technology Committee at the 1986 SPE/IADC Drilling Conference. It was subsequently approved by the lADC Board of Directors and designated to take effect concurrent with the 1987 SPE/IADC Drilling Conference. A description of the 1987 lADC Fixed Cutter Bit Classification Standard follows [54]. 

A difficulty arises in describing the precise chemical nature of many inhibitor formulations that are actually used in practice. With the advancing technology of inhibitor applications there are an increasing number of formulations that are marketed under trade names. The compositions of these are, for various reasons, frequently not disclosed. A similar problem arises in describing the composition of many inhibitor formulations used in the former Soviet Union. Here the practice is to use an abbreviated classification system and it is often difficult to trace the actual composition, although in many cases a judicious literature search will provide the required information.
