Abstract: A system for processing fine powders includes a hopper for dispensing powder material through a hopper outlet, and a feeding chamber positioned downstream of the hopper outlet to receive the powder material and convey the powder material to a plasma torch. The system also includes an auger positioned at the hopper outlet, a mechanical vibrator and a mesh screen attached to a flange of the feeding chamber, and a pneumatic system providing a gas flow sufficient to propel the powder material without extinguishing a plasma of the plasma torch.

Abstract: The embodiments disclosed herein are directed to systems, methods, and devices for producing materials having desired characteristics using microwave plasma. In some embodiments, performing an iterative process may be used to produce a material having desired characteristics, the process comprising forming a microwave plasma within the reaction chamber, analyzing the plasma to determine if properties of the plasma are within a range expected to produce the desired characteristics of the material; and adjusting, based on the analysis of the plasma, one or more parameters. In some embodiments, an extension tube is provided within a microwave plasma apparatus to extend the length of a microwave plasma.

Abstract: A modular barrel system for firearm includes a first barrel segment and a second barrel segment. Each barrel segment comprises a tubular member having an axial bore, a proximal end, and a distal end. The proximal end of the first barrel segment has a first threaded element for removably attaching the first barrel segment to a firearm. The distal end of the first barrel segment has a second threaded element and the proximal end of the second barrel segment has a third threaded element which is complementary with the second threaded element, the third threaded element for removably attaching the second barrel segment to the first barrel segment. In a further aspect, method for the manufacture of a modular barrel system are provided.

Abstract: In one aspect, a sensor system for advanced smart weapons barrels includes one or more sensors, the sensors connected to a processor by way of conductive elements. The smart weapons barrel system may include one or more barrel segments, such segments being removably attached to each other. In certain embodiments, the sensors are positioned along the barrel segments and generate an electrical signal in response to a projectile being fired by the host firearm as the projectile moves past the respective sensor. The processor receives raw data from the sensor signal and may extrapolate and/or calculate further information in order to determine any number of a variety of metrics or other data analysis, including, but not limited to, round count projectile velocity, rate of fire, etc.
