Patent relating to methods and devices for controlling the propagation of sound and particularly to tunable polymer-based sonic structures.

This invention is comprised of a process for recovering nuclear fuel from spent fuel assemblies that employs a single canister process container. The cladding and fuel are oxidized in the container, the fuel is dissolved and removed from the container for separation from the aqueous phase, the aqueous phase containing radioactive waste is returned to the container. This container is also the disposal vessel. Add solidification agents and compress container for long term storage.

Precision finishing apparatus utilizing line contact polishing to produce optical quality parts. A rotatable cylinder is horizontally disposed above a workpiece which is mounted on a rotatable, and horizontally and vertically adjustable chuck. Predetermined surfaces can be cut into the surface of the cylinder to produce figures of revolution, such as aspheres,, when the workpiece is being rotated.

The present invention relates generally to ringlight for providing illumination about a central viewing area and more particularly to an improved ringlight design suitable for use in automatic gaging applications conducted in hostile radioactive environments. It is a further object of the present invention to provide a ringlight which is relatively simple in construction and with few parts, and which is thus very reliable in operation. The above and other objects are achieved in the present invention by a ringlight providing an annular array of light-emitting elements centered about a viewing passage, wherein the improvement comprises: a first annular body, a second annular body mounted concentrically within the first annular body so as to form an annular void and light-emitting aperture therebetween, and a plurality of optical fibers extending into the void with end portions thereof secured therein so as to form an annular array of optical fiber end surfaces at said light-emitting aperture, the first and second bodies cooperating to angle the end portions of the plurality of optical fibers toward a central axis of the viewing passage.

Patent for a turning plow attachment which prepares the soil to receive seed, whereby reducing labor.

Patent for improvements in steam-generating plants. The most notable change is that the boiler proper is separate from the furnace proper but still contains the water, steam, and fire tubes.
