The use of the refrigerant potential of cryogenic fluids is now in its infancy. The high driving force — the low temperature boiling point — has over the years many times intrigued scientists and engineers to consider its utilization for many situations. On the lab bench, it was successful; but in most commercial applications its cost far over-shadowed its ease of handling, its speed of freezing, its flexibility, its seemingly limitless capacity, and its 100% reliability.

ABSTRACTLow-temperature-grown (LTG) GaAs is a unique material that has been used in a variety of device applications to achieve record performance. LTG GaAs used as a buffer layer eliminates sidegating and backgating and in GaAs integrated circuits. Record output power density (1.57 W/mm) and superior microwave-switch performance were demonstrated when LTG GaAs was used at a gate insulator in a metal-insulator-semiconductor field-effect transistor. High-speed (0.5 ps) and high-voltage (1 kV) LTG GaAs photoconductive switches have also been demonstrated. Using the same material, researchers have demonstrated highresponsivity (0.1 A/W), wide-bandwidth (∼ 375 GHz) LTG GaAs photodetectors. Devices incorporating LTG GaAs are currently being optimized for systems applications. LTG GaAs technology can enhance system performance and enable new systems for military and commercial applications in the areas of radar, communications, instrumentation, and highspeed computing.

Abstract INDALLOY 281-338 is a tin-base alloy that can be melted easily. It is non-eutectic alloy and melts through a temperature range of 281-338 F. It provides scientists and engineers with an easily castable material that is ready for use soon after it freezes; in addition, it can be recovered readily and recycled into new uses any number of times. Among its many uses are fusible mandrels for electroforming, proof casting in foundries, low-temperature solder, holding jet engine blades for machining and dies for wax patterns for investment casting. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on casting, heat treating, and machining. Filing Code: Sn-10.

Unpleasant Smell

The light oils obtained by the destructive distillation of Cannel-coal at a low temperature, contain, besides the hydrocarbons of the marsh-gas and benzol series, other substances, which are attacked by concentrated sulphuric acid. If the oil, which has been repeatedly shaken with this acid, be subjected to distillation, the hydrocarbons which are unacted upon volatilize first, and a black tarry liquid, equal in bulk to about half the crude oil, remains behind. On heating this residue more strongly, a brown oil, having an unpleasant smell, comes over at about 200°C. ; the temperature rises gradually up to 300°C., and at last a black pitchy mass is left in the retort. Even after repeated rectifications the oil always leaves a solid black residue behind, and it was only by continued fractional distillations over solid caustic potash and metallic sodium, that I succeeded in isolating substances possessing nearly a constant boiling-point and volatilizing almost completely. The compounds which I thus obtained from Cannel-coal oil, boiling below 120°C., are hydrocarbons of the general formula (C n H 2 n -2 ) 2 , as the following analyses and determinations of the vapour-densities show:— (1) C 12 H 20 boiling-point 210°C. ( a ) 0·262 substance gave 0·840 carbonic acid and 0·290 water. ( b ) 0·1978 substance gave 0·635 carbonic acid and 0·2195 water.
