Abstract: A hollow spherical projectile is constructed from a plurality of curved structural segments and has a plurality of openings. The projectile can be fired by a conventional paintball marker with a high degree of ballistic accuracy. The projectile is reusable and is fabricated from a flexible and resilient material. The outer surface of the projectile exhibits low friction, achieved by the material itself or by having a low friction coating applied. The projectile possess and transmits less kinetic energy than a conventional paintball and therefore inflicts less pain and damage upon impact. Fabrication can be accomplished by 3D printing, or molding as a single seamless piece, or as a plurality of pieces which are then assembled.

Abstract: A system, method, and apparatus for determining a profile of an ion beam are provided. The apparatus comprises a measuring device positioned along a path of the ion beam, a drive mechanism, and a first plate rotatably coupled to the drive mechanism. The drive mechanism is operable to rotate the first plate about a first axis through a path of the ion beam, therein selectively blocking the ion beam from reaching the measuring device. The apparatus may comprise a second plate further rotatably coupled to the drive mechanism, wherein the drive mechanism is operable to rotate the second plate about the first axis through the path of the ion beam independently from the rotation of the first plate, therein further selectively blocking the ion beam from reaching the measuring device. The drive mechanism may further linearly translate first plate and/or second plate through the ion beam.

The connector shell is made of a second material. A coefficient of thermal expansion of the first material is greater than a coefficient of thermal expansion of the second material. A conductor extends at least partially through the neck of the connector shell. Solder connects the neck to the base.

Abstract: A system and method of forming a hermetic seal between a lens or window and a lid, which minimizes bending moments, and therefore, bifringance on the window or lens is disclosed. This is accomplished by use of a transition member, specific geometries, and selection of the coefficient of thermal expansion of the materials to insure that the solder joint is in compression on cool down and solder strains are maintained within acceptable limits. The transition member may be soldered or welded to lid or integral through machining.

The stator further rotates about the first axis in reaction to the rotation of the rotor, particularly in the reversal of direction of motion of the workpiece, thus acting as a reaction mass to the rotation of one or more of the rotor, scan arm, and workpiece.

Abstract: A system for forming particulate material in a bulk form comprises a compression tower having a top and sides depending therefrom. A compression chamber having side walls and an open bottom is reciprocatively mounted to said tower for deposit of loose particulate material therein. The system further includes a first conveyor assembly displaced from said tower. In its extended position, the chamber contacts the first conveyor assembly and the bottom of the chamber is closed thereby. A vacuum blower draws loose particulate material into the chamber through an inlet and compresses it against the first conveyor assembly. A ram assembly within the chamber further compresses the loose material into a bulk form atop the conveyor belt. When the chamber and ram assembly are returned to their retracted positions, the material bulk is transferred downstream by the first conveyor assembly to a space between vertically spaced second and third conveyor assemblies.
