20110267618 | PASSIVE REFLECTIVE TRACKING MEDIA COMPOSITIONS AND METHODS FOR COVERTLY TRACKING OBJECTS - A passive reflective tracking media includes a plurality of multi-layer particles including at least one layer of a high refractive index material and at least one layer of a low refractive index material. The particles are configured to reflect ambient electromagnetic radiation at one or more signature wavelengths. Methods of applying the tracking media to a target object, detecting the tracking media, and fabrication the tracking media are also described. | 11-03-2011 |
20130101788 | OPTICAL AIR SLIT AND METHOD FOR MANUFACTURING OPTICAL AIR SLITS - A structure having an optical slit therein. The structure includes a substrate having an opening therethrough and a metal layer disposed on the substrate, such metal layer having a photolithographically formed slit therein, such slit being narrower than the opening and being disposed over the opening, portions of the metal layer disposed adjacent the slit being suspended over the opening and other portions of the metal layer being supported by the substrate. | 04-25-2013 |

20150071799 | Self-Aligning and Vibration Damping Bearings in a Submersible Well Pump - An electrical submersible pump assembly has a centrifugal pump with stages, each having an impeller and a diffuser. A shaft extending from an electrical motor rotates the impellers. In the stages, a thrust runner is coupled to the shaft for rotation in unison. A bushing is non rotatably mounted in a receptacle in the diffuser. The bushing has a bore that receives the body of the runner in sliding, rotating engagement. The bushing has a thrust receiving end engaged by the thrust face of the runner in rotating, sliding engagement to transfer thrust from the runner to the diffuser. An elastomeric compliant member between a cylindrical exterior of the bushing and the receptacle allows limited radial movement of the bushing relative to the diffuser. | 03-12-2015 |

20100108392 | Method and apparatus for constructing deep vertical boreholes and underground cut-off walls - A method and apparatus for constructing large vertical boreholes and underground cut-off walls is disclosed. A drill rig assembly with double rotary heads drives a small diameter drill string and a much larger diameter drill string which is concentric with the smaller drill string and has a donut shaped drill bit configuration at the lower end thereof. Preferably, a steerable mud motor/drill is provided on one end of the small drill string and is guided to make as vertical a borehole as possible. In a preferred embodiment, the small inner drill is advanced to the full depth using the steerable mud motor/drill to achieve a high degree of verticality and a slight smaller casing is installed and used as a verticality guide for the much larger diameter outer drill string. In a further embodiment, the inner drill string is advanced a predetermined distance, then the outer string is advanced using the inner string as a verticality guide, these steps being repeated in alternating fashion to the final depth. | 05-06-2010 |
