In the mid 1930's the Diesel engine, which formerly was used only as a large, low-speed machine, was developed into a smaller
high-speed engine for use in trucks, busses, and tractors. Along
with these changes in mechanical design came many problems, of
which a major one was lubrication. Because ordinary...
For the sample of wide-ringed Douglas-fir discussed in this report, the relationship between specific gravity and percentage of summerwood is linear over a range of 16 to 60 percent summerwood content of the annual ring. The specific gravity of the summerwood and springwood portions of 96 dissected annual rings is...

A study was made of the possibility of producing pulp of viscose rayon grade from three Chilean hardwoods, coigue, tepa, and ulmo. Unbleached pulps were made from the three woods by (1) the neutral sulfite semichemical process with and without steam prehydrolysis, (2) a water prehydrolysis-sulfate process, and (3) the...
In this investigation the addition of hydrogen bromide
to 3-methylcyclohexene has been studied in order to see if
the theory of hyperconjugation could be extended to include
olefins of this type. Since the olefin has an equal number
of hydrogens on both carbons carrying the double bond, a
mixture of...
