Abstract: A high-powered microwave torch provides a tunable cavity to move between a first and second mode for ignition and steady-state operation. The tuning may be accomplished by adjusting end plates of a cylindrical cavity consistent with a desired TE01? resonant mode. A swirl promoting spacer system allows cantilevered coaxial tubes to accommodate gas flow rates, and a junction between the tube assembly and a plasma nozzle provides a compression engagement resistant to temperature-expansion induced stress.

Abstract: A recycling loop nitric acid generator uses a high-pressure nitrogen and oxygen loop with high-temperature plasma to produce concentrated nitric acid suitable for making transportable ammonium nitrate organic fertilizer from scavenged ammonia from manure.

Abstract: Aspects of the present disclosure describe systems and methods for implementing the sale of a media package that has one or more digital assets and/or platform features and a first level of digital rights management (DRM) protections from a first purchaser to a second purchaser. The DRM protections may limit which digital assets may be sold. The level of DRM protection on the media package may be changed to a second level before being delivered to the second purchaser. The changed DRM protection may restrict the future sale of the digital assets and/or platform feature(s) remaining in the package. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
