Abstract: A passive optical alignment coupling between an optical connector having a first two-dimensional planar array of alignment features and a foundation having a second two-dimensional planar array of alignment features. One of the arrays is a network of orthogonally intersecting longitudinal grooves defining an array of discrete protrusions that are each in a generally pyramidal shape with a truncated top separated from one another by the orthogonally intersecting longitudinal grooves, and the other array is a network of longitudinal cylindrical protrusions. The cylindrical protrusions are received in the grooves, with protrusion surfaces of the cylindrical protrusions in contact with groove surfaces and the top of the discrete protrusions contacting the surface bound by the cylindrical protrusions.

Abstract: The premixed pilot nozzle includes axially elongated tubes defined within a plenum between an outer shroud and a first shroud disposed radially inward of the outer shroud. The tubes extend between tube inlets defined through a forward face and tube outlets defined through an aft face. A second shroud is disposed radially inward of the first shroud, thereby defining a fuel plenum between the first shroud and the second shroud, and the fuel plenum is in communication with a gaseous fuel supply. A fuel injection port, which is positioned between the tube inlet and the tube outlet of each tube, is in fluid communication with the fuel plenum. An air supply configured to fluidly communicate with the tube inlet of each tube. The second shroud defines a second plenum therein, the second plenum being coupled to a source of a non-combustible fluid.

Abstract: An intravascular catheter for peri-vascular and/or peri-urethral tissue ablation includes multiple needles advanced through supported guide tubes which expand around a central axis to engage the interior surface of the wall of the renal artery or other vessel of a human body allowing the injection an ablative fluid for ablating tissue, and/or nerve fibers in the outer layer or deep to the outer layer of the vessel, or in prostatic tissue. The system may also include a means to limit and/or adjust the depth of penetration of the ablative fluid into and beyond the tissue of the vessel wall. The catheter may also include structures which provide radial and/or lateral support to the guide tubes so that the guide tubes expand uniformly and maintain their position against the interior surface of the vessel wall as the sharpened injection needles are advanced to penetrate into the vessel wall.
