System and method for inspecting parts using dynamic response function
A system and method for the non-destructive testing of additively manufactured parts. An input mechanism excites with an excitation force (e.g., a vibration) an additive manufacturing build structure, which includes a part on a build platform, to induce a dynamic response in the part. An output mechanism (e.g., a non-contact transducer) senses the induced dynamic response in the part. A processor determines and examines the relationship between the response and excitation to identify an indication of a defect in the part, and communicates an alert if the indication is identified. The processor may compare the phase, magnitude, coherence, or time delay of the relationship to a reference relationship and/or may compare the modal frequency or the modal damping to a reference to identify a deviation greater than a pre-established threshold. |

Wind aeolipile
Described herein is essentially a high-efficiency, hybrid fluid-aeolipile. In operation, this hybrid device is placed in the stream of a moving fluid, preferably air. Energy is extracted from the fluid stream by directing a portion of the stream through and, optionally, around the device. As the fluid-flow moves through the device, it is directed into nozzles. These nozzles, which are free to pivot in a cyclical manner, employ the established phenomenon of “nozzle-effect” to accelerate the velocity of the air-flow passing through them, which is ultimately ejected from each nozzle tip, producing thrust. This thrust, amplified by nozzle-effect, drives the nozzles to pivot around a shared axis. The wind energy, thereby converted into cyclical motion, that may be used to perform useful work, is converted with greater efficiency, than is possible in conventional blade-type wind turbines. |

Paraffin control unit
A paraffin control unit with staged high voltage temperature controlled electric immersion heaters to maintain the paraffin component of the crude oil in the liquid phase. The paraffin control unit removes large volumes of naturally occurring fine sand from the incoming liquids while also removing the crude oil from the influent fluid stream, the natural gas from the influent fluid stream, salt water from the influent fluid stream, all while maintaining the temperature of the crude oil fraction above the cloud point of its paraffin constituent. The removed sand is collected in sand pans and is automatically removed at timed intervals.

Macroporous oxygen carrier solid with a refractory feldspar/feldspathoid, method for the preparation thereof, and use thereof in a chemical-looping oxidation-reduction method
The invention relates to an oxygen carrier solid, its preparation and its use in a method of combustion of a hydrocarbon feedstock by active mass chemical-looping oxidation-reduction, i.e. chemical-looping combustion (CLC). The solid, which is in the form of particles, comprises an oxidation-reduction active mass composed of metal oxide(s) dispersed in a ceramic matrix comprising at least at least one feldspar or feldspathoid with a melting point higher than 1500° C., such as celsian, and has, initially, a specific macroporous texture. The oxygen carrier solid is prepared from a precursor of the ceramic matrix, obtained from a macroporous zeolitic material with zeolite crystals of a specific size, and a precursor of the oxidation-reduction active mass. |
