Mirror fusion reactors. [Conceptual design studies for power plants]
We have carried out conceptual design studies of fusion reactors based on the three current mirror confinement concepts: the standard mirror, the tandem mirror, and the field-reversed mirror. Recent studies of the standard mirror have emphasized its potential as a fusion-fission hybrid reactor, designed to produce fission fuel for fission reactors. We have designed a large commercial hybrid based on standard mirror confinement, and also a small pilot plant hybrid. Tandem mirror designs include a commercial 1000 MWe fusion power plant and a nearer term tandem mirror hybrid. Field-reversed mirror designs include a multicell commercial reactor producing 75 MWe and a single cell pilot plant.

Evaluation of laser welding techniques for hydrogen transmission. Progress report, April 1, 1978--April 30, 1978
Machining of the A106B GTA and EB welded specimens was completed. Laser welding of the AISI 304L and ASTM A106B materials is continuing. Tensile testing of the ASTM A106B EB welded specimens was initiated and completed. Testing of the ASTM A106B EB welded material indicated generally lower ductility than the parent material. Low-cycle fatigue testing of the ASTM A106B material in 13.8 MPa hydrogen indicates reductions in mean life of approximately 50 and 27% due to the GTA and EB welding respectively. (LK)

Diagnostics for the laser fusion program: plasma physics on the scale of microns and picoseconds
Laser induced fusion is the forerunner of a class of inertial confinement schemes in which hydrogen isotopes are heated to thermonuclear conditions in a very short period. The process is characterized by such short time scales that fuel confinement is achieved through its' own finite mass and expansion velocity, approaching 1 ..mu..m/psec for ignition temperatures of order 10 keV (10/sup 8/ /sup 0/K). With current laser powers limited to several terrawatts one readily estimates, on the basis of energy conservation, target mass, and expansion velocity, that target size and laser pulse duration are on the order of 100 ..mu..m and 100 psec, respectively. Within these constraints, targets have been heated and confined to the point where thermonuclear conditions have been achieved. This paper describes a sampling of diagnostic techniques with requisite resolution (microns and picoseconds) to accurately describe the dynamics of a laser driven compression. As discussed in each case cited, these in turn provide insight to and quantitative measure of, the physical processes dominating the implosion. The success of the inertial confinement fusion program is strongly dependent on the continued development of such diagnostics and the understanding they provide.

Bed Spring.
Patent for a new and improved bed-spring. This design consists in "the adjustable tie that connects the springs beneath the slats. This device is simple, cheap, convenient, and durable. It is adjustable to slats placed at different distances apart, and will remain in position when placed upon the slats, holding the diagonal rows of springs in a straight line, causing the springs to remain uniform all over the bed" (lines 72-80).

Car Coupling.
Patent for a new and improved coupling for railroad cars. This design "consists in the combination, with a draw-bar having a socket and buffer-prongs on its ends, of a ball in the socket, coupling-hooks pivoted between jaws connected with the ball, a weighted stem projecting from the ball, and a sliding latch-rod for engaging with the stem and automatically releasing it when the cars come together" (lines 8-15).
