Triose structures. The two central structures for glyceraldehyde enantiomers are written according to the Mills convention (wedges out of the paper, dashed lines going in). The next structures are the full Fischer convention and the outer structures an abbreviated Fischer convention in which the hydrogen and central carbon atoms are implicit. [Pg.2]

Two techniques are used commercially to produce ultra-fine milks of lime, namely slaking at high shear rates and milling conventional milks. [Pg.237]

The three principal domestic uses for rice in 1988 were direct food (61%), processed food (18%), and beer (20%). The direct food use figure includes the conventional white milled rice plus specialty rice products (parboiled, precooked, aromatic, brown, and prepackaged mixes) shipped directly from the rice mills. The specialty products account for approximately one-fifth of the direct food use. Approximately two-thirds of the direct food use rice is ultimately distributed to consumers through retail outlets and one-third through food service outlets. [Pg.358]

Some of the information available on designs of com wet-milling plants in which com oil and other products are produced indicate that integration with an alcohol plant may be more efficient than a conventional com alcohol plant. [Pg.39]

P/M Tool Steels. In conventionally produced high alloy tool steels (slowly cooled cast ingots), carbide tends to segregate (48). Segregated clusters of carbide persist even after hot working, and cause undesirable effects on tool fabrication and tool performance. P/M tool steels, on the other hand, provide very fine and uniform carbides in the compact, the final bar stock, and the tools. Several tool steel suppHers consoHdate gas-atomized tool steel powder by HIP to intermediate shapes, which are then hot-worked to final mill shapes. Water-atomized tool steel powder is also available (see also T OOL materials). ... [Pg.189]

Aluminum alloys are commercially available in a wide variety of cast forms and in wrought mill products produced by rolling, extmsion, drawing, or forging. The mill products may be further shaped by a variety of metal working and forming processes and assembled by conventional joining procedures into more complex components and stmctures. [Pg.123]

Modijications to the Recope Cycle. The recovery system is a principal capital cost in a kraft mill. Consequently, any recovery process that is less expensive to build can improve pulping economics. There have been numerous attempts to improve the kraft recovery process. Two examples are the direct alkaline recovery scheme (DARS) and the autocausticizing scheme using sodium borates (37). Both schemes eliminate the lime loop of the conventional kraft mill. As of 1996, neither is commercially used. [Pg.270]

Urethanes are processed as mbber-like elastomers, cast systems, or thermoplastic elastomers. The elastomer form is mixed and processed on conventional mbber mills and internal mixers, and can be compression, transfer, or injection molded. The Hquid prepolymers are cast using automatic metered casting machines, and the thermoplastic peUets are processed like aU thermoplastic materials on traditional plastic equipment. The unique property of the urethanes is ultrahigh abrasion resistance in moderately high Shore A (75—95) durometers. In addition, tear, tensUe, and resistance to many oUs is very high. The main deficiencies of the urethanes are their resistance to heat over 100°C and that shear and sliding abrasion tend to make the polymers soft and gummy. [Pg.234]
