“…3) The Gouge-Joule effect, which has been described previously [4] , Since the compression cylin¬ der cools quite rapidly, only the other effects and smaller dimension changes in the jig are present after 20 minutes of cooling. At Tg the apparent volume contraction is reduced and the Gouge-Joule effect ceases to exist, and the force decay levels off.…”

“…The compounds in group IV show low force decay and good sealing (1) during assembly of the seal [ 1 ]. During cooldown the sealing force is maintained at a safe level if the initial force is large enough.…”

The functions of the National Bureau of Standards are set forth in the Act of Congress, March 3, 1901, as amended by Congress in Public Law 619, 1950. These include the development and maintenance of the na¬ tional standards of measurement and the provision of means and methods for making measurements consistent with these standards; the determination of physical constants and properties of materials; the development of methods and instruments for testing materials, devices, and structures; advisory services to government agen¬ cies on scientific and technical problems; invention and development of devices to serve special needs of the Government; and the development of standard practices, codes, and specifications. The work includes basic and applied research, development, engineering, instrumentation, testing, evaluation, calibration services, and various consultation and information services. Research projects are also performed for other government agencies when the work relates to and supplements the basic program of the Bureau or when the Bureau's unique competence is required. The scope of activities is suggested by the listing of divisions and sections on the inside of the back cover.

“…In recent years, the modification of polyethylene by copolymerization with propylene to prevent an undue degree of crystallization has resulted in a promising elastomer having good aging and weathering resistance. Applications 71,91,111,131,191,211,251,261 Natta, in an extensive review of polyolefin elastomers (78C), has described their synthesis and has related detailed molecular structure to the viscoelastic and other physical properties of the vulcanizates.…”

“…Elastomeric compounds were sought for use in such special conditions as high temperatures (261), cryogenic (76°t o 300°K .) temperatures (191), space environment (111), and in solid rocket propellants (71,181). Recent laboratory findings indicate that rubber and asphalt blends are superior to asphalt alone in road surfaces (211).…”
