Consider for Use

Copper bus bars are used instead of aluminium bus bars since copper has a higher melting point and better conductivity than aluminimn. Optimise cost of bus bar by considering area of cross section required for same current to be carried. [Pg.219]

HT motors/energy-efhcient motors instead of LT motors. [Pg.219]

Light reflecting colours and sunlight through transparent/translucentroof instead of electrical lights at the workplace. [Pg.219]

Better thermal insulation to minimise load on air conditioning and refrigeration systems. [Pg.219]

Chilled water (at +5 to +8 °C) instead of brine at (—5 to —8 °C) is preferable if the process unit can be run satisfactorily. Refrigeration plants consume less power in the previous case for operation. [Pg.219]


Alloys with other useful properties can be obtained by using yttrium as an additive. The metal can be used as a deoxidizer for vanadium and other nonferrous metals. The metal has a low cross section for nuclear capture. 90Y, one of the isotopes of yttrium, exists in equilibrium with its parent 90Sr, a product of nuclear explosions. Yttrium has been considered for use as a nodulizer for producing nodular cast iron, in which the graphite forms compact nodules instead of the usual flakes. Such iron has increased ductility. [Pg.74]

Cera.micA.bla.tors, Several types of subliming or melting ceramic ablators have been used or considered for use in dielectric appHcations particularly with quartz or boron nitride [10043-11 -5] fiber reinforcements to form a nonconductive char. Fused siHca is available in both nonporous (optically transparent) and porous (sHp cast) forms. Ford Aerospace manufactures a 3D siHca-fiber-reinforced composite densified with coUoidal siHca (37). The material, designated AS-3DX, demonstrates improved mechanical toughness compared to monolithic ceramics. Other dielectric ceramic composites have been used with performance improvements over monolithic ceramics (see COMPOSITE MATERIALS, CERAMIC MATRIX). [Pg.5]

In the electronics industry. Pis find wide appHcations as a dielectric material for semiconductors due to thermal stabiHty (up to 400°C) and low dielectric constant. Pis are being considered for use in bearings, gears, seals, and prosthetic human joints. The intended part can be machined or molded from the PI, or a film of PI can be appHed to a metallic part. Because of their superior adhesion, dielectric integrity, processing compatibUity, and lack of biological system impact. Pis have been used in many biological appHcations with particular success as body implants. [Pg.533]

High density tungsten alloy machine chips are recovered by oxidation at about 850°C, foUowed by reduction in hydrogen at 700—900°C. Typically, the resultant powders are about 3-p.m grain size and resinter readily. There can be some pickup of refractory materials used in furnace constmction, which must be controUed. This process is important commercially. Eor materials that may be contaminated with other metals or impurities, the preferred recovery process is the wet chemical conversion process used for recovery of tungsten from ores and process wastes. Materials can always be considered for use as additions in alloy steel melting. [Pg.285]

Several promising antibacterial compounds are available and may be considered for use in U.S. aquaculture. In addition to sarafloxacin, other quinolones, flumequine and oxolinic acid, are already registered in Europe. However, resistance to both of these compounds developed in bacteria in just a few years (20). Enrofloxacin, [95106-60-6], C22H22FN2O2, a quinolone product of Bayer A.G. (Germany), is also a candidate for aquaculture registration in Europe and may be considered for registration in the United States. [Pg.324]

Black and colored plates can also be obtained from chromic acid baths. The plates are mostly oxides (177). Black chromium plating bath compositions are proprietary, but most do not contain sulfate. The deposit has been considered for use in solar panels because of its high absorptivity and low emissivity (175). [Pg.143]

Sihcon carbide fibers exhibit high temperature stabiUty and, therefore, find use as reinforcements in certain metal matrix composites (24). SiUcon fibers have also been considered for use with high temperature polymeric matrices, such as phenoHc resins, capable of operating at temperatures up to 300°C. Sihcon carbide fibers can be made in a number of ways, for example, by vapor deposition on carbon fibers. The fibers manufactured in this way have large diameters (up to 150 P-m), and relatively high Young s modulus and tensile strength, typically as much as 430 GPa (6.2 x 10 psi) and 3.5 GPa (507,500 psi), respectively (24,34) (see Refractory fibers). [Pg.6]

Over the 40-yr history of shock-compression science, numerous physical phenomena have been considered for use in detecting wave profiles. Few of the devices have actually been used for a significant and persistent study. Part of this history is connected to the difficulty in actually developing a credible... [Pg.62]

Cyclic loading significantly reduces the amount of allowable stress a material can withstand. If data are not available on the endurance limit of a material being considered for use, a percentage of its tensile strength can... [Pg.84]

Some nitriles are expl, especially if they contain several —CN groups or a combination of —CN and —N02 groups. Other nitriles have been considered for use in double-base propints as they cool the flame and provide longer burning times a variety of alkyl nitriles have been investigated as plasticizers (Ref 7)... [Pg.286]

Nitroindene was considered for use in the USAM54 Time Fuze but was found to be too sensitive to impact (Ref 3)... [Pg.326]

With reference to the mil literature available for unlimited publication, acetone peroxide has been considered for use as a detonating expl (Ref la), but was found to be too volatile at RT for such an application (see Vol 1, A42 R to A45-R)... [Pg.676]

Hydrazinium diperchlorate (HP2) is one of the higher energetic oxidizers considered for use in composite solid propints with hydrocarbon binders. Its other advantages include high density, high burning rate, and moderate projected cost. Its shortcomings include relatively poor stability to vibrational and thermal shock... [Pg.891]

Most raw water sources considered for use as boiler MU have been treated or conditioned either by a water utility (providing city water) or in-house (providing industrial water). They are supplied to the boiler plant clean and relatively free of suspended solids, colloidal material, organics, and iron. In hard water areas there also may be some reduction in hardness and alkalinity provided. Where boiler plant raw water (RW) quality is still unacceptable for the particular boiler plant needs, additional pretreatment pre-boiler conditioning or external treatment) may be required. [Pg.304]

L.4 The compound diborane, B2H6, was at one time considered for use as a rocket fuel. Its combustion reaction is... [Pg.114]

The trend in CVD metallization is toward greater use of copper, and the refractory metals and their silicides in multilayered metallization designs, typically consisting of metal-silicide contacts, refractory-metal barriers, and copper or an aluminum alloy as the principal interconnect metal. Other metals deposited by CVD such as chromium, molybdenum, platinum, rhodium, and ruthenium are also actively considered for use as conductors. [Pg.372]

These results open the exciting possibility of using degradable, tyrosine-derived polymers as "custom-designed" antigen delivery devices. On the other hand, our results indicate that the immunological properties of tyrosine-derived polymers will have to be carefully evaluated before such polymers can be considered for use as drug delivery systems or medical implants. [Pg.225]

Another excipient used in feed additive premixes is a diluent used to dilute or standardize activity. Diluents are similar in composition to grain carriers, except the particle size is generally smaller. No attempt is made to absorb the active drug to the individual particles of the diluents. If a liquid is used it is mainly for dust control. A diluent is considered for use when the level of the active ingredient components in the premix approaches or exceeds 50% of the product or when two or more active components vary greatly from one another in density [13]. Examples of diluent materials are ground limestone, sodium sulfate, kaolin, corn cob flour, and ground oyster shells. [Pg.725]

Alternative final cover systems, such as the innovative evapotranspiration (ET) cover systems, are increasingly being considered for use at waste disposal sites, including municipal solid waste (MSW) and hazardous waste landfills when equivalent performance to conventional final cover systems can be demonstrated. Unlike conventional cover system designs that use materials with low hydraulic permeability (barrier layers) to minimize the downward migration of water from the cover to the waste (percolation), ET cover systems use water balance components to minimize percolation. These cover systems rely on the properties of soil to store water until it is either transpired through vegetation or evaporated from the soil surface. [Pg.1058]

There are two different catalyst manufacturers whose products are being considered for use in a commercial scale reactor facility. Both products are 3.2 mm diameter spherical pellets that... [Pg.527]

Tall cultivars with greater distances between ears and leaves as well as the upper leaf distances should be considered for use, because they are less susceptible to splash dispersal of spores. [Pg.380]

Only four plant species, i.e., Vicia faba, Allium cepa, Pisum sativum and Triticum turgidum, responded adequately to the Feulgen procedure, and were considered for use in the successive experiments. These species, together with the corresponding mutagenic compounds used and the mutagenicity tests adopted (see below in Sect. 2.4.) are listed in Table 4. [Pg.283]
