Abstract: Matrix basalt reinforcing members for concrete. The basalt members are specifically formed to provide tension support having a beneficial use with pervious concrete used in large areas such as sidewalk and parking lot. The basalt reinforcing members add structural rigidity to the pervious concrete, making the pervious concrete capable of supporting heavy loads such as trucks without cracking while allowing water to pass through the concrete. The basalt reinforcing members are formed from roving crosses and interlaces in between each side of the figure 8 shape to mitigate potential for sheer at crossovers.

Abstract: A hydraulic setting tool for packers capable of mechanically setting the packer and opening a valve in the packer in one trip. The tool comprises an outer sleeve and an inner mandrel coaxially disposed within the outer sleeve and adapted to move axially relative to the outer sleeve. The tool further comprises three locking mechnisms that unlock under different fluid pressure loads. Two of the locking mechanisms lock the inner mandrel to the outer sleeve in a run-in position. Once a sufficient fluid pressure has been reached to unlock both of these locking mechanisms, the inner mandrel moves upward relative to the outer sleeve to set the packer. A spring forces the inner mandrel into a third position relative to the outer sleeve, which is maintained by the third locking mechanism. This third position is used to open the packer valve.

Abstract: A downhole tool apparatus for insertion into and sealing engagement with a wellbore. The apparatus comprises a tube having an expandable diameter, and a gripping member joined to the tube adapted to engage a portion of the wellbore to limit movement of the tube within the wellbore. The tube may also include a sealing member adapted to mate with the wellbore to form a sealing engagement.

Abstract: Provided is a photodetector that detects missile launches from an above-flying surveillance platform through clouds. The plume detector includes a passive electro-optical sensor which detects the narrow spectral emissions in a rocket engine plume during launch thereof. By detecting a launch upon rocket engine ignition, despite a cloud layer, a gain of up to thirty seconds or more of launch warning is realized and the location of the launch can be accurately determined and the trajectory of such rocket more accurately plotted for enhanced response to such launch. The plume detector of the invention can be carried on a platform such as an aircraft or an orbiting satellite. In each case such detector can spectrally isolate the narrow spectral emissions of interest of a missile or other rocket, as it is launched, for faster tracking and response.

Abstract: Pulp and/or paper samples are scanned with a Laser Raman Spectroscopic probe, utilizing Raman spectroscopic technology, to generate Raman spectroscopic images of all or selected ones of the constituents and/or contaminants contained in the sample, to compare the same with a library of Raman spectroscopic fingerprints of known constituents and/or contaminants, and to identify and communicate data on all or selected ones of the constituents and/or contaminants for purposes of controlling the paper making process and/or determination of the quality of the paper produced.

Abstract: An improved downhole tool apparatus for limiting the extrusion of a packer element. The apparatus includes a packer mandrel having a packer element assembly disposed in a wellbore. Packer retaining shoes are disposed about the packer mandrel at the ends of the packer element assembly. The packer retaining shoes have an inner retainer and an outer retainer. The inner retainer has a plurality of segments having gaps therebetween that expand in width when the retaining shoe is moved from an initial position in which it is disposed about the packer mandrel to an expanded position wherein it engages the wellbore to limit the extrusion of the packer element assembly. The outer retainer is likewise made up of a plurality of segments having gaps therebetween that will expand. The outer retainer engages the wellbore to limit the extrusion of the packer element assembly.

Abstract: A downhole tool for sealing a wellbore. The downhole tool includes a packer with a ball seat defined therein. A sealing ball is carried with the packer into the well. The movement of the sealing ball away from the ball seat is limited by a ball cage which is attached to the upper end of the packer. The ball cage has a plurality of ports therethrough for allowing flow into the ball cage and through the packer at certain flow rates. A spring is disposed in a longitudinal opening of the packer and engages the sealing ball to prevent the sealing ball from engaging the ball seat until a predetermined flow rate is reached. When the packer is set in the hole, flow through the frac plug below a predetermined flow rate is permitted. Once a predetermined flow rate in the well is reached, a spring force of the spring will be overcome and the sealing ball will engage the ball seat so that no flow through the frac plug is permitted.
