A device is provided for sealing an inner tube and an outer tube without excessively deforming the tubes. The device includes two ferrules which cooperate to form a vacuum-tight seal between the inner tube and outer tube and having mating surfaces such that overtightening is not possible.

A free electron laser and free electron laser amplifier using beam transport devices for guiding an electron beam to a wiggler of a free electron laser and returning the electron beam to decelerating cavities disposed adjacent to the accelerating cavities of the free electron laser. Rf energy is extracted from the electron beam after it emerges from the wiggler by means of the decelerating cavities which are closely coupled to the accelerating cavities, or by means of a second bore within a single set of cavities. Rf energy extracted from the decelerated electron beam is used to supplement energy provided by an external source, such as a klystron, to thereby enhance overall efficiency of the system.

It is the primary objective or aim of the present invention to provide an electrically conductive composition for the fabrication of susceptors useful for induction melting of uranium and uranium alloys and to also provide such a composition for forming crucibles and other containment vessels utilized to contain uranium at elevated temperatures. This composition does not appear to interact with molten uranium, since there is no significant reaction between the compositional consituents of the susceptor or containment vessel and the confined uranium. This objective is achieved by utilizing a sintered ceramic composition which consists essentially of about 13-67 vol. % of a refractory metal carbide and a nonconductive oxide selected from a group consisting of zirconium oxide, calcium aluminate, yttria, and combinations thereof.

Patent for a type-writing machine that has an improved variable line spacer. The simple and durable line spacer has the minimum number of parts and is easily adjustable to any distance.

Patent for a valve gear for steam engines that can reverse or stop the rotation of the engine shaft, with illustrations.

Patent for improvements for burners. It is related explicitly to hydrocarbon burners. Its purpose is to keep the oil and steam separate as they leave the burner by keeping them in two separate streams.

Patent for a foot operated wagon braking mechanism, including illustrations. Patent for a better alternative to lever brakes on buggies and wagons as the braking mechanism is "out of the way, and not noticeable or prominently visible from the sides of the vehicle".

Patent for a new and improved wheeled vehicle. This design consists in "[a] one-wheeled sulky in which are combined the single wheel, the frame, the thills, the seat, the standards, and the rods or braces" (lines 54-57).

Patent for a new and improved display rack and stand. This design "is to provide a novelty rack for displaying or exhibiting fancy goods, wearing-apparel, hats, bonnets, and other articles; and to such end the invention consists of a standard suitably supported by a base-piece, a collar or ring, and a series of arms sustained by the collar or ring, with their inner arms resting in frictional contact with the surface and the stand, the collar or ring being of such diameter as to stand at a distance from the standard to form a fulcrum or bearing for the arms at a short distance from their inner ends" (lines 8-19).
