Abstract: This invention performs the gas pressurization task of a centrifugal compressor gas turbine engine in a new way. In this invention gas compression takes place by using pinwheel-like thrusters to induce a very high velocity full forced vortex in the gas being compressed. Much higher “tip” velocities can be achieved because no strength-limited solid centrifugal impeller is required to spin up the gas. Due to the consequent very high vortex velocity a single stage pressure ratio of twenty five to one, or more, may be possible. Because there is no high pressure turbine, the gas pressure delivered to some downstream useful work device is much higher than is the case with conventional gas turbine engines. The invention's compressor requires no major moving parts except for the gas flow. The consequence is that the invention is predicted to have substantially better performance and general characteristics than conventional gas turbine engines.

Abstract: Described are computer-based methods and apparatuses, including computer program products, for radar data processing. In some examples, the system includes a communication module, a surface discovery module, a linear condensation identification module, and a structure generation module. The communication module is configured to receive 3-dimensional image data from an imaging device. The surface discovery module is configured to rotate the 3-dimensional image data around an axis in 3-dimensional space of the 3-dimensional image data. The linear condensation identification module is configured to identify linear condensations in the rotated 3-dimensional image data. The structure generation module is configured to generate a structure based on the linear condensations and the rotated 3-dimensional image data.

Abstract: A rotary fluid coupler includes a first fluid conduit, a second fluid conduit in fluid communication with the first fluid conduit and rotatable relative to the first fluid conduit, and a first fluid conduit/second fluid conduit seal at a joint between the first fluid conduit and the second fluid conduit. A return fluid conduit has an inlet end that receives fluid leaked through the first fluid conduit/second fluid conduit seal, and a return/joint seal that seals against leakage from the return fluid conduit to an external environment. A fluid-pressure biasing source is in communication with the return fluid conduit to move fluid away from the inlet end through the return fluid conduit, and back to a fluid source.

Abstract: A process and apparatus is disclosed for imposing selectable, sequential, spatial modulations upon a reference beam for the storage in a suitable medium of a hologram. Changing the spatial modulations enables the storage of several, different holograms in the same medium. Each hologram can be individually reconstructed by imposing upon the reconstructing illumination beam the same spatial modulations.
