Manufacturing loss

Interpretations A and D can easily be checked by taking additional samples from later production runs. If the means seen for many production lots tend to concentrate near 100%, then the emulsion results seen here would just be chance result on the low side if the means concentrate near some other number, then a formulation error, a manufacturing loss, or sample work-up could be to blame. [Pg.287]

Low potency value due to manufacturing loss is another common issue in developing low-dose dmg products. Loss of drag during manufacture of the product is highly related to the physical properties of the drug and specific unit operations associated... [Pg.36]

In reporting information, the respondent is required to provide numbers that represent its best estimate based on readily available data. Exact numbers, therefore, are not required and EPA s assessment has been that permitting estimates to be reported will provide data sufficient for the purposes of the rule and make reporting easier. In some areas, such as the estimate of manufacturing losses, the respondent is required to specify the estimated accuracy of the quantities reported. Concerning the accuracy of reporting customer activities, the Eorm requires estimates of quantities by customer use only within a +/—50 percent accuracy. Where a respondent cannot report within +/—5 percent, or where a secrecy agreement with a customer forecloses disclosure, the respondent may report unknown. ... [Pg.216]

During the plastic material life cycle, plastics waste is recycled as a resource. The amount and type of recyclable plastic depends upon the composition and quantity of waste from the municipal and industrial waste streams. Industrial waste from the manufacture of plastic products is regarded as a manufacturing loss the reduction of plastics waste, as a result of recycling the material, increases productivity and reduces the manufacturing loss. [Pg.69]

In recent years, industry-wide yields of products per ton of seed have averaged 335 lb (151 kg) of oil, 935 lb (421 kg) of meal, 450 lb (207 kg) of hulls, and 158 lb (76 kg) of linters, with manufacturing loss of 100 lb (45 kg) per ton. These figures vary from area to area and from mill to mill, depending on the character of the seed, the type of process used, and the marketing practices. [Pg.247]

There is a great loss of tocopherol in the storage of potato chips and french fried potatoes. One study showed aftermanufacture losses of tocopherol in potato chips stored at 73°E (23 C) of 71% in 1 month and 77% in 2 months. When the chips were frozen at 10 E (-12°C), the losses were 63% in 1 month and 68% in 2 months. The after-manufacture losses of french fries stored at 10 E (-12 C) were 68% in 1 month and 74% in 2 months. [Pg.1108]

When collecting a sample, for instance, only a small portion of the available material is taken, increasing the likelihood that small-scale inhomogeneities in the sample will affect the repeatability of the analysis. Individual pennies, for example, are expected to show variation from several sources, including the manufacturing process, and the loss of small amounts of metal or the addition of dirt during circulation. These variations are sources of indeterminate error associated with the sampling process. [Pg.62]

Finally, the dielectric properties of a nonpolar polymer are modified by inclusion of even small amounts of a polar comonomer. In coatings applications the presence of polar repeat units in an otherwise nonpolar polymer reduces the tendency for static buildup during manufacture, printing, and ultimate use. On the other hand, in dielectric applications this increases the power loss and must be kept to a minimum, even to the exclusion of polar initiator fragments. [Pg.469]

Four other groups of synthetic adhesives find uses in secondary processing, ie, overlaying, assembly gluing, etc, and in furniture and cabinet manufacture. Poly(vinyl acetate) (PVA) adhesives are widely used in appHcation of veneers and other overlays to panel substrates and in some unit-assembly operations. PVA adhesives are an emulsion of polyvinyl acetate in water and cure by loss of water. The PVA adhesives are somewhat... [Pg.378]

The bottoms from the solvent recovery (or a2eotropic dehydration column) are fed to the foremns column where acetic acid, some acryflc acid, and final traces of water are removed overhead. The overhead mixture is sent to an acetic acid purification column where a technical grade of acetic acid suitable for ester manufacture is recovered as a by-product. The bottoms from the acetic acid recovery column are recycled to the reflux to the foremns column. The bottoms from the foremns column are fed to the product column where the glacial acryflc acid of commerce is taken overhead. Bottoms from the product column are stripped to recover acryflc acid values and the high boilers are burned. The principal losses of acryflc acid in this process are to the aqueous raffinate and to the aqueous layer from the dehydration column and to dimeri2ation of acryflc acid to 3-acryloxypropionic acid. If necessary, the product column bottoms stripper may include provision for a short-contact-time cracker to crack this dimer back to acryflc acid (60). [Pg.154]

Solventless Extrusion Process. The solvendess process for making double-base propellants has been used ia the United States primarily for the manufacture of rocket propellant grains having web thickness from ca 1.35 to 15 cm and for thin-sheet mortar (M8) propellant. The process offers such advantages as minimal dimensional changes after extmsion, the elimination of the drying process, and better long-term baUistic uniformity because there is no loss of volatile solvent. The composition and properties of typical double-base solvent extmded rocket and mortar propellant are Hsted ia Table... [Pg.45]

Fan Rating. Axial fans have the capabiUty to do work, ie, static pressure capabiUty, based on their diameter, tip speed, number of blades, and width of blades. A typical fan used in the petrochemical industry has four blades, operates neat 61 m/s tip speed, and can operate against 248.8 Pa (1 in. H2O). A typical performance curve is shown in Figure 11 where both total pressure and velocity pressure are shown, but not static pressure. However, total pressure minus velocity pressure equals static pressure. Velocity pressure is the work done just to collect the air in front of the fan inlet and propel it into the fan throat. No useflil work is done but work is expended. This is called a parasitic loss and must be accounted for when determining power requirements. Some manufacturers fan curves only show pressure capabiUty in terms of static pressure vs flow rate, ignoring the velocity pressure requirement. This can lead to grossly underestimating power requirements. [Pg.112]

Incorporation of OH is another critical aspect of the oxidation chemistry. Reduction to the ppb level is necessary for the manufacture of low loss optical fiber. Hydrogen is iacorporated iato the glass according to the reaction... [Pg.254]

Other important properties that can be measured in the laboratory include sealabiHty, printabiHty, or coating adhesion. Many of these tests have been developed by the film manufacturer in cooperation with customers and are specifically designed to measure product performance in the end use. Some tests, like sealabiHty, can be standardi2ed to time, pressure, and temperature of sealing with instmment-measured peel values, but other tests are subjective, such as evaluations of printing loss to puUoff by adhesive tape. [Pg.374]

Packaging (qv) represents the largest market area for film and sheeting materials (15). It is a complex market with so many categories that it is difficult to get an accurate measure of end usage for specific materials (16). The stmcture of the marketplace which uses both monolayers of film, as well as converted composite stmctures and laminates, adds to the complexity. The ultimate user or packager may purchase raw film direcdy from a manufacturer, or use the same film laminated to one or more other films or substrates through a converter. The converter may buy film or extmde his own supply. Resin sales to film producers do not always correlate with their film sales, because of scrap and yield losses. [Pg.383]
