摘要:

There was a time when “face‐changing” a region was an acceptable adjunct to resource improvement. The current accent on ecology has discouraged this attitude of laissez‐faire. New methodologies exist and are being created for planning water‐quality environments; it remains to implement them.

摘要:

A NWC panel evaluated the problems and recommended a plan for nationwide abatement of water pollution during a 10‐yr period. Its proposal is based upon a facilities‐planning effort to identify the most economical solutions, a federal construction‐grant program to end in 10 yr, and placing management of public systems on a utility basis with self‐financing after the 10‐yr period—at which time federal subsidies would end.

摘要:

The Ball and Cone Valve Com. was reorganized 2 yr ago. Its purpose: to start fresh in order to determine more objectively what was needed in the way of ball and cone valve standards. The first question it asked was, “What is the purpose of a standard?” The details followed, and the committee expects to have a standard available later this year.

摘要:

The ability of a coating material to withstand the torturous process of wear is not the only criterion involved in its selection. Preparation of the surfaces of the valve to obtain adherence, handling characteristics of the coating, and overall economics—even the question as to whether the coating will be available years hence for whatever jobs are necessary—all play a role in material selection.
