摘要： A rotating magnetic memory, such as a disk drive using sector servo information, is initialized with servo information by first using the dedicated product head assembly, including transducers and the mounting and accessing mechanisms associated therewith, to write on the innermost and outermost data tracks, following which the tracks written by each transducer are read using a precision servowriter mechanism which is then positioned to duplicate the access path of the product head assembly and determine the position of such innermost and outermost tracks. By then offsetting the precision servowriter by a half track pitch and writing the servo information to form equally spaced tracks, the disk is initialized with full track pitch servo information which is positioned and aligned with the position and alignment of the dedicated product head assembly.

摘要： 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.

摘要： 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.

摘要： 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 inner retainer segments cover the gaps that exist between the outer retainer segments and the outer retainer segments cover the gaps that exist between the inner retainer segments so that extrusion is limited. The retaining shoes provide enhanced high temperature and higher pressure performance in that extrusion in wells having high temperature and high pressure is severely limited if not completely prevented.

摘要： 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.

摘要： There is disclosed a metal sheet product, more particularly formed food container stock and/or industrial sheet product, which has been treated with an ester-free, lubricant composition that is suitable for direct food contact. This composition consists essentially of: (i) about 10-90 wt. % of a polyalphaolefin; (ii) about 10-90 wt. % of an oleic acid; (iii) about 0-60 wt. % of an isostearic acid; and preferably, about 10-35 wt. % isostearic acid. It should be noted that especially good smudge testing results were observed with the presence of oleic acid. In alternative embodiments, the lubricant composition further includes: (iv) up to about 5 wt. % of an antioxidant, preferably about 0.1-3 wt. % butylated hydroxytoluene; and (v) up to about 10 wt. % of a conductivity enhancer, such as about 2-7 wt. % lecithin. When applied in total deposited weights of about 0.1-30 mg/ft2 per side, this invention produces formed food container stock or industrial sheet having improved formability and relatively lower smudge results when compared to its fatty acid and ester-containing alternatives.

摘要： An improved downhole tool apparatus including, but not limited to, packers and bridge plugs which more fully utilize highly stressed non-metallic components, including slips, slip wedges, and packer element retaining shoes than prior tools. The non-metallic packer element retaining shoes of the present invention are preferably made of separate shoe segments initially held in place by at least one retaining band. Such non-metallic packer element shoes do away with troublesome prior art metallic shoes and backups which tended to spin upon each other or about the mandrel while milling or drilling the tool out of a wellbore. Therefore, the subject invention increases the ability to drill or mill downhole tools out of a well bore in less time than it would take with using conventional or non-conventional drilling or milling techniques or equipment.

摘要： Both an improved loudspeaker enclosure and an improved acoustical process for generating sound radiation in a room is herein disclosed. Basically, the walls of the improved enclosure include a loudspeaker, and a sound transmission port for transmitting sound generated by the back of the loudspeaker cone into the room. The interior of the enclosure includes a tuned acoustical chamber for absorbing the even and odd harmonics of the system resonance frequency, and a compression chamber acoustically coupled at one end to the back of the loudspeaker cone. The compression chamber is acoustically coupled to both the tuned acoustical chamber and the transmission port of the enclosure walls by means of an acoustical coupling. When the transmission port is located in the back wall of the enclosure, the sound transmitted by the transmission port may be directed into and amplified by an acoustical structure formed by the back enclosure wall, the room floor, and the room walls, where it reflects and combines with the sound radiation generated by the front of the loudspeaker cone.
