The invention described herein relates to methods of forming graded polymeric coatings or films on a desired substrate and of forming metallic coatings on polymeric or other nonmetallic substrates. In particular, it relates to methods of forming such coatings or films by sorption and/or diffusion of metals into coatings or films of polymeric material deposited by conventional techniques on a desired substrate.

Monitoring of power systems performance data for Pioneer 10 and Pioneer Saturn spacecrafts continued. Net power output for either system during mid-January of 1981 was 112 watts. Power degradation has, for several years, been stable between 4 and 5 watts per year. Viking 1 Lander data acquisition has been resumed following the conclusion of Saturn encounter activities. Figures show the Mars Lander performance history of Viking 1. These data include both the minimum and maximum data for each of the SOL days plotted to show the range of performance experienced on the Martian surface.

A groove refinishing tool is disclosed which utilizes a finishing wheel which is controlled by an air grinder motor. The air grinder motor is mounted on a main body section which is pivotally attached to a shoe element. The shoe element contains guide pins which guide the shoe element on the groove to be refinished. Application of pressure on the main body element compresses a weight counterbalance spring to extend the finishing wheel through the shoe element to refinish the groove surface. A window is provided for viewing the refinishing operation. Milling operations can also be performed by replacing the finishing wheel with a milling wheel.

This paper summarizes the basis for the present optimism in the magnetic fusion program, and describes some of the remaining tasks leading to a demonstration power reactor and the primary technologies necessary for that endeavor.

This paper summarizes several studies of fusion reactors based on the compact torus (CT). A wide variety of reactor configurations can be projected within present understanding of the possible types of CT and their macroscopic stability and confinement properties. Three types of CT are considered here, the field-reversed-configuration having B/sub Toroidal/ = 0, the Spheromak with B/sub T/ not equal to 0, and CT's formed with particle rings. For each type, either fixed or moving-ring possibilities are offered along with pulsed or steady operation. In all cases the CT configuration lends itself to simplified blanket and coil design. In certain, important cases a reactor-scale CT is predicted to produce small unit power (10-100 MW/sub e/) facilitating small-scale pilot plants and eventual modularity.

During the past several years a rapid increase has occurred in compact torus (CT) research in the United States, reflecting renewed interest in this simplified reactor consequences of this configuration. This paper reviews early approaches to CT formation and results and summarizes present experimental studies. Recent experiments have demonstrated a number of macroscopic aspects of the CT, including the conditions under which a macroscopically stable CT can be formed and maintained. Scaling experiments and more detailed studies of plasma transport in progress are discussed along with experiments under construction.
