Draw the temper

Advcmictges of the Aholiol Lamp,—The lamp has this advantage over the forge-Are it draws the temper very evenly and the temper color can be readily seen, as tho Aame of alcohol makes no smoke to obscure it. Even for small tempering, wheu once employed, no gunsmith will think of discontinuing its use. 

In mid-eighteenth-century France, an eccentric figure of violent chemical opinions and mild temper was drawing the attention of the Parisian intellectual elite. Guillaume-Franfois Rouelle (1703-1770), an inspiring yet extremely absent-minded and easily distracted demonstrator of chemistry at the Jardin du roi, was staging chemical spectacles for a diverse audience of prospective apothecaries, physicians, physicists, philosophes, and literary talents. ... 

Thermocouples. In order to obtain some information on the temper atures of the thermal and biological shields, thermocouples will be embedded at 47 points throughout the reactor structure. The locations of these 47 points are given in Table 2.8,A. As a factor of safety, two thermocouples will be attached to the steel or embedded in the concrete at these points. It should be noted that the locations given in Table 2.8.A are recommended best points, but construction difficulties may cause a shift in some of these locations. As built drawings should be consulted for final placement data. It is currently planned to bring out the thermocouple leads in small conduits to Junction boxes on the north and east faces of the reactor structure. 

Most wrought alloys are provided in conditions that have been strengthened by various amounts of cold work or heat treatment. Cold worked tempers are the result of cold rolling or drawing by prescribed amounts of plastic deformation from the annealed condition. Alloys that respond to strengthening by heat treatment are referred to as precipitation or age hardenable. Cold worked conditions can also be thermally treated at relatively low temperatures to affect a slight decrease in strength (stress rehef annealed) to benefit other properties, such as corrosion resistance and formabiUty. 

From the correlation between the ancient pottery and modern clay one can draw several significant conclusions in addition to the most immediately obvious one that the matching ancient pots were locally made. The amount of temper in the ancient pottery, as evidenced by our comparison with the clay source, has not diluted or otherwise significantly altered the compositional pattern of the ceramic. Also the pottery must not have significantly changed in composition during burial. In addition we observed a small but significant difference between the composition... 

Art s utopia, the counter-factual yet-to-come , is draped in black.45 Darkness marks the place where possibility holds out against actuality. Black works against the deceitful sensuality of culture s facade. Adorno s insistence on black reacted to what seemed a world of ever-louder colours. In 1959 he observed colour s high-pitched shriek in all too much more intense and conspicuous colours . These new colours turned book jackets into advertisements for themselves, in efforts to shake off all that is bookish, old-fashioned and retrogressive about the book.46 Parodic sheen was too able to be misunderstood. Colour may be life s colourful reflections, but it was also a mechanism for drawing attention to the commodity heaven of the post-war. These new commodity colours were synthetic, and the synthetic came to be a testament to the new improved temper of life itself. 

It is tempting to draw analogy with the development of other analytical technologies (NMR, FAB-MS) and conclude that protein crystallography will soon leave the incubator of "big machine physics" to become an everyday, routine tool used in the medicinal chemistry laboratory. Hopefully, this chapter has shown some of the subtle complexities of sample preparation and handling, data collection, and refinement, etc. that temper this vision and will likely keep this a specialized field for some time.
