โœฆ Synopsis

mum spacing between wires. This was pointed out by the writer ~ixteen years ago, 1 and H. B. Dwight has shown in a recent article 2 that if two parallel three-phase circuits are carried on the same pole line, the arrangement of Fig. 3 is decidedly preferable to the more usual arrangement of Fig. 4. By applying formula (3), it is easy to calculate the flux surrounding any one of the conductors, whatever may be the spacing between them, and when the circuits are arranged as in Fig. 4, it will be found that there is considerable unbalance of induced e.m.f.'s and that the average reactance drop is appreciably greater than with the phases arranged as in Fig. 3, or with the two circuits carried on separate pole lines.

The effective thermal conductivities of silica aerogel foam [0.1 (10)-3 kg m -3 nominal density] filled with liquid n-H 2, liquid n-D 2 and an equimolar mixture of liquid H2-D 2 were measured near 19.6 K. Our measured value of 97 mW m -1 K -~ for hydrogen filled foam is essentially the same as for t

The thermal conductivity o5 hydrogen has been measured between 90 ยฐ and 280ยฐK with a modified compensated hot wire system using a cryostat designed speeially for the system and in which the temperature can be maintained COllstant to within 0.01ยฐC.
