Materials eliminate

The enclosure is constructed of non-magnetic material, generally aluminium, in view of its low cost and weight as compared to copper The nonmagnetic material eliminates hysteresis and eddy current losses in the enclosure, as i result of mutual induction,... [Pg.935]

Innovative chemical synthesis procedures have been proposed as offering potential for economical and environmentally friendly routes to a variety of chemicals. These novel chemical reactions also offer potential for increasing the inherent safety of processes by eliminating hazardous materials, eliminating chemical intermediates, or allowing... [Pg.38]

Al-Mg-Si alloys are strengthened by precipitation hardening in which MgjSi is formed. They are not very susceptible to stress-corrosion cracking which only occurs in specimens subjected to a high solution-treatment temperature followed by a slow quench Ageing such material eliminates susceptibility . [Pg.1276]

It is particularly worthwhile to search the literature for data generated by others before embarking on a durability trial, including data published in the technical literature and manufacturers own data sheets. Even if no totally suitable data is available there may be information which can add to, or help substantiate, your own results (for details see Chapter 10). However, all such data should be seen in the context of the general environmental resistance of materials, which will at least enable the potential candidates to be short listed and unsuitable materials eliminated. [Pg.48]

This method is more modern than the last and it gives details for making a lower starting material, eliminating the need for purchasing (5,6,7,8) tetrahydroisoquinoline methiodide. [Pg.96]

Green chemistry efficiently utilizes (preferably renewable) raw materials, eliminates waste, and avoids the use of toxic and/or hazardous reagents and solvents in the manufacture and application of chemical products. [Pg.10]

The amounts of materials eliminated by switching to the PCF technology, based on a 5-year production period, are detailed in Table 7.1. [Pg.156]

Thus, a daughter structure with a new periodicity of d = (n - y)dH. can be obtained. Hereafter we shall call the total operation the shear operation. Because the composition of the daughter phase generally differs from that of the mother phase, the composition of the material eliminated by operation (2) has to differ from that of the mother structure (see below). It is also to be noted that operations (l)-(3) do not represent the mechanism of... [Pg.116]

A solid plastic may be ground to a solid powder and then used to apply a plastic coating to a metal product, either for decorative reasons (color) or for functional performance such as insulation or corrosion resistance. Plastics most often used in this way include nylon, vinyl, acrylic, polyethylene, polypropylene, and epoxy. Coating without solvents is beneficial both economically and environmentally, and 100 percent utilization of material eliminates waste. After the powder is bonded to the metal surface, it is often reheated to flow into a more uniform coating and, in the case of thermosetting resins, to complete the cure reaction. [Pg.680]

Laser cutting is a fast growing process. The laser can act as a materials eliminator. Concentrating its energy on a small spot, it literally vaporizes the material in its path. If the workpiece is held stationary, the laser drills a hole. If the piece is moved, it slits the material. The induced heat is so intense and the action of the laser is so fast that only little heating of the adjacent areas of the piece takes place. [Pg.568]

In spite of continuing worries about the dangers of pesticides, we still depend heavily on them. The Environmental Protection Agency reports (EPA) that around 500,000 metric tons of pesticides are used in the United States every year. We rely on them for disease control, agricultural production, preservation of buildings and materials, elimination of biting and troublesome organ-... [Pg.809]

Uses less raw materials Eliminates water-induced degradants Improves process cycle time Prevents particle segregation Facilitates continuous manufacturing Improves content uniformity... [Pg.3161]

Eliminate notches in design or minimize notch effect as much as possible carefully inspect welds and base material eliminate or minimize vibrations, stress levels. [Pg.281]

A. A radioactive material must be eliminated from the body to remove its hazard. Detoxification, which is effective against chemical hazards, will not be effective since radioactivity is not modified by chemical changes. The methods of elimination include renal excretion for most soluble materials, elimination in the feces for materials that are retained in the gut or which can be secreted in the bile, and exhalation for volatile materials and gases. Chelating agents, e.g., calcium or zinc DTPA (diethylenetriamine pentaacetic acid), if administered soon after exposure, are effective in enhancing the elimination of certain radioisotopes. These materials are not very effective for radioisotopes that have been incorporated and fixed in organs and tissues, e.g., bone. [Pg.102]

Direct analysis of solid materials eliminates the precipitation steps referred to above. Clays and soils can be evaluated by TG to determine water content, carbonate content, and organic matter content. [Pg.496]

In discussing experimental techniques, Dunn and Taylor [134] mention that while dilatometric studies with degassed materials eliminated the induction period, the start of the reaction was difficult to observe since the initiation of the polymerization takes place during the thermal expansion period as the equipment was thermostated. [Pg.260]
