[en] Magnetization, specific heat, and electrical resistivity measurements were made on single crystals of the filled skutterudite compound PrOs₄As₁₂. Specific heat measurements indicate an electronic specific heat coefficient γ ∼ 50-200 mJ/mol K² at temperatures 10 K (le) T (le) 18 K, and ∼ 1 J/mol K² for t (le) 1.6 K. Magnetization, specific heat, and electrical resistivity measurements reveal the presence of two, or possibly three, ordered phases at temperatures below ∼ 2.3 K and in fields below ∼ 3 T. The low temperature phase displays antiferromagnetic characteristics, while the nature of the ordering in the other phase(s) has yet to be determined

[en] A locking nut assembly for attachment of a threaded element has at least one longitudinal channel to a support member, the assembly comprising a nut for engagement with the threaded element, the nut being provided with at least one opening, a locking sleeve for insertion within the nut, the sleeve being formed with at least one prong in parallel alignment with the channel of the threaded element to fit into the channel, the prong being formed with a foot arranged to interact with the support member to inhibit relative motion therebetween, and at least one portion of the inserted locking sleeve being deformed into the opening of the nut to restrain relative movement of the nut with respect to the threaded element.

[en] This standard practice covers full ported cast iron gate valves with flanged or threaded ends. These valves are suitable for general purpose use

[en] This device includes protective means comprising a rigid case housing the unit of control motors and not less than one protective sleeve in which is housed an articulated arm. The rigid case includes at least one removable panel on a side opposite that on which the articulated arm is fixed so that the latter and its control unit may be removed from the enclosure after the panel has been opened

[en] The development of nuclear standards is an active and necessary endeavor that is concerned with the safe, orderly, and economic development of nuclear potential. There are almost 4100 people from the teachnical community who are presently involved either in writing nuclear standards, including codes, or in the management and processing roles necessary for their approval and promulgation. This document identifies the current participation of each individual as member, chairman, cochairman (vice-chairman), or secretary of about 700 standards development committees and groups. The standards committees and groups are identified with the organizations that are responsible for the preparation, review, and maintenance of the standards and that provide support through supervisory committees and headquarters staff. This directory includes four major sections: personnel, employers, committees, and a Key-Word-in-Context (KWIC) Index of committee titles. It can also be used to identify the participation of employers as well as to recognize the contributions of individuals to the often interdisciplinary activity of standards development
