摘要:
A thermochemical labyrinth reactor is disclosed. The reactor has a reoxidation zone and a reduction zone with electric heaters. A recuperation zone connects the reduction and reoxidation zones with first and second channels, the first channel adjoining the second channel, being separated by windows allowing an exchange of thermal radiation between channels while preventing gas exchange. The reactor also includes reactor plates composed of a reactive material, and a transit system running through the three zones, with the transit system configured to shuttle the plates between the reduction zone and the reoxidation zone, moving the plates along a circuit. The reactor also has a feedstock gas emitter to introduce a feedstock gas flowing opposite the movement of the plates. A gas extractor is configured to extract a product gas resulting from the feedstock gas being split by the oxidizing reactive material. All three zones are surrounded by an insulating housing.

The present disclosure includes a racking system for receiving, storing, and/or delivering rods and tubulars. The racking system includes a rack having a plurality of beams configured to support a plurality of rods, a plurality of tubulars, or both. each of the plurality of beams includes a proximal end and a distal end. The racking system further includes a plurality of indexers aligned with or proximal to the proximal ends of the plurality of base beams, wherein each of the plurality of indexers includes a series of rotating holders configured to transport the plurality of rods, tubulars, or both to and from the rack. Additionally, the racking system further includes a jack coupled to the distal end each of the plurality of base beams, wherein the jack raises and lowers the distal end of the base beam in relation to the proximal end.
摘要:
A tricone drill bit having a hollow housing and leg sections holding rotatable cones for drilling rock. The drill bit encloses a cavitation reactor. The cavitation reactor includes liquid and being capable of receiving a laser beam. The cavitation reactor forms cavitation bubbles fin the liquid in response to the laser beam. The cavitation reactor includes a mask having sub millimeter sized apertures for directing cavitation jets formed on the collapse of the cavitation approximately 0.1-10 microns. These reentrant cavitation jets pass easily through the apertures of the mask and to the rock to enable the tricone drill be to operate more efficiently.
