Cool Sounds

OK. The Feds have stated their case. Sounds cool. Sounds scary. Now let s see what I have found from years of practical experience buying chems and from digging around the chemical community and law enforcement agencies. And let s seejust how these shiny new laws are being applied. Don t worry, folks. It ain t no big thang ... [Pg.13]

Fusion-cast refractories are formed by first melting the material in an electric arc. The Uquid is poured into a mold and allowed to cool. Various annealing processes and refining techniques ensure a uniform and stmcturaUy sound shape. The case form is then cut or ground to size. [Pg.31]

Satisfactory engine performance is assured by maintaining a minimum log that allows comparison of present characteristics with past records of (1) cylinder exhaust, cooling water, and supercharger exhaust temperature for similar loadings, (2) running sounds and smokiness of exhaust, and (3) engine efficiency and losses. [Pg.2493]

Air terminal unit assembly The air terminal unit, consisting of casing, mixing section, flow control, heating, cooling, filters, fans, sound attenuators, etc. [Pg.1412]

The passage of a sound wave along a tube, so that no energy is dissipated by friction, is an example of a compressional wave of permanent type, and Newton applied his equation (1) to determine the velocity of sound in air. For this purpose he took e as the isothermal elasticity of air, which is equivalent to assuming that the temperature is the same in all parts of the wave as that in the unstrained medium. Since air is heated by compression and cooled by expansion, the assumption implies that these temperature differences are automatically annulled by conduction. Taking the isothermal elasticity, we have ... [Pg.146]
