Numbering and identification

Process instrumentation displays should be arranged in relation to each other according to their sequence of use or functional relationship to the components they represent. They should be arranged in their functional groups, whenever possible, to provide a viewing flow from left to right or from top to bottom. [Pg.245]

Process vessels and equipment should be provided with identification in the field that is legible from approximately 30 meters (100 ft.) away. It should be viewable from the normal access points to the facility or equipment and is of colors contrasting with the surrounding background. The identifications normally consist of the equipment identification number and the common name of the equipment, e g., V-200, Propane Surge Drum . This is beneficial during routine and emergency periods where the quick identification of process equipment is critical and necessary from a distance. [Pg.245]

Use a chisel or other safe means to damage the threads on the valve spud in such a way that the cylinder cannot be readily repaired. Likewise obliterate markings on the cylinder including the registered symbol, serial number, and identification markings. [Pg.196]

If the symbol, name, or specific characteristics of a data item (e.g., a gene, stock, EST) are already known, a text query is appropriate. Text queries can be simple or complex. In a simple query, words or numbers (a string of text) are entered, and mmy fields (repositories of information in the database) are searched. In a complex query, only certain fields or combinations of fields are searched. In addition, the words typed into a query form may be controlled or free text. Vor free text, any word (or keyword) can be typed and will be searched for. For fields using controlled terms, only certain words can be used, terms that are identifiers (such as symbol, name, line number, and identification number) or terms that are part of a controlled vocabulary. [Pg.512]

The interaction between nuclei splits resonances into multiple peaks, the number and relative intensity of which also assist in qualitative identification of the proton responsible for the absorption. [Pg.464]

The effects of a rather distinct deformed shell at = 152 were clearly seen as early as 1954 in the alpha-decay energies of isotopes of californium, einsteinium, and fermium. In fact, a number of authors have suggested that the entire transuranium region is stabilized by shell effects with an influence that increases markedly with atomic number. Thus the effects of shell substmcture lead to an increase in spontaneous fission half-Hves of up to about 15 orders of magnitude for the heavy transuranium elements, the heaviest of which would otherwise have half-Hves of the order of those for a compound nucleus (lO " s or less) and not of milliseconds or longer, as found experimentally. This gives hope for the synthesis and identification of several elements beyond the present heaviest (element 109) and suggest that the peninsula of nuclei with measurable half-Hves may extend up to the island of stabiHty at Z = 114 andA = 184. [Pg.227]

The nominal chemical composition and identification of the most important copper castiag alloys are Hsted ia Table 7. These alloys are ideatifted by name and by the Unified Numbering System. The use of names is not recommended. [Pg.245]

Both common and systematic names of compounds are used throughout this volume, depending on which the Editor-in-Chief felt was more appropriate The Chemical Abstracts indexing name for each title compound, if it differs from the title name, is given as a subtitle Systematic Chemical Abstracts nomenclature, used in both the 9th and 10th Collective Indexes for the title compound and a selection of other compounds mentioned in the procedure, is provided in an appendix at the end of each preparation. Registry numbers, which are useful in computer searching and identification, are also provided in these appendixes. Whenever two names are concurrently in use and one name is the correct Chemical Abstracts name, that name is adopted. For example, both diethyl ether and ethyl ether are normally used. Since ethyl ether is the established Chemical Abstracts name for the 8lh Collective Index, it has been used in this volume The 9th Collective Index name is 1,1 -oxybisethane, which the Editors consider too cumbersome. [Pg.220]

The major impetus for the development of solid phase synthesis centers around applications in combinatorial chemistry. The notion that new drug leads and catalysts can be discovered in a high tiuoughput fashion has been demonstrated many times over as is evidenced from the number of publications that have arisen (see references at the end of this chapter). A number of )proaches to combinatorial chemistry exist. These include the split-mix method, serial techniques and parallel methods to generate libraries of compounds. The advances in combinatorial chemistry are also accompani by sophisticated methods in deconvolution and identification of compounds from libraries. In a number of cases, innovative hardware and software has been developed tor these purposes. [Pg.75]

The code requires the submission of an instrument and piping (low sheet. All instruments should be numbered for identification and ihe actual instruments labeled. The code is very helpful in recommending the range and sensitivity required, and close adherence is recommended. [Pg.423]

CAS number and the chemical name reported on page three must exactly match the listed section 313 CAS number and chemical name. Chemical categories should not be reported with a CAS number. A generic chemical name should only be provided if you are claiming the section 313 chemical identity as trade secret. Chemical names should be taken directly from the list in this document (see pages 40-48). Mixture names are to be entered in Part III, Section 1.4 if that is the sole identification. Mixture names that include the name (or CAS number) of one or more section 313 chemical(s) are not valid. [Pg.91]

In addition to the Vendor s standard identification, tags shall be furnished to show the service, N P Refinery s tag number, and N P Refinery s order number for each tag item listed on the Purchase Order. [Pg.314]

Emergency notification should include chemical name and identification of the chemical by number estimation of quantity released time and duration of release mode of release (air, water, or soil) known health risks associated with the emergency applicable precautions and name and phone number of a contact person. All emergency notifications require a written follow-up as soon as possible [2]. [Pg.170]

Whatever the records, they should carry some identification in order that you can determine what they are, what kind of information they record, and what they relate to. A simple way of doing this is to give each record a reference number and a name or title. [Pg.495]

Records can take various forms reports containing narrative, computer data, forms containing data in boxes, graphs, tables, lists, and many others. Where forms are used to collect data, they should carry a form number and name as their identification. When completed they should carry a serial number to give each a separate identity. Records should also be traceable to the product or service they represent and this can be achieved either within the reference number or separately, providing the chance of mistaken identity is eliminated. The standard does not require records to be identifiable to the product involved but unless you do make such provision you will not be able to access the pertinent records or demonstrate conformance to specified requirements. [Pg.495]
