20150257551 | Jewelry Organizer Stand - A jewelry organizer stand has a frame with a mesh region for mounting post-type earrings and pins and a mounting bar region of parallel mounting bars for holding various clips with extensions. The clips with extensions can include ring bars for holding rings, necklace bars for holding necklaces, spin-rings for holding beads, pendants and pins, and locking bracelet hooks for holding bracelets. The organizer stand can be pivotably mounted on a base so that it can be turned around. The height can be about that of an adult. The base is at least as wide as the frame so that the organizer will not fall over even if a large unbalanced weight of jewelry is placed on it. | 09-17-2015 |

20160002995 | INFLATABLE SEAL WITH FABRIC EXPANSION RESTRICTION - A diverter flowline seal assembly for use in subsea drilling. The seal assembly includes a seal body having an inner diameter end and an outer diameter end formed of an inflatable elastomeric material having a first modulus. The inner diameter end of the seal body includes two diametrically opposed axially inward lip portions and two diametrically opposed axially outward base portions. Integrated with the inflatable elastomeric material at the base portions of the inner diameter end of the seal body is a material having a modulus that is higher than the modulus of the inflatable elastomeric material so as to prevent the radial expansion of the lip portions and the base portions of the inner diameter end of the seal body. | 01-07-2016 |

20120181032 | DISINTEGRATING BALL FOR SEALING FRAC PLUG SEAT - A composition for a ball that disintegrates, dissolves, delaminates or otherwise experiences a significant degradation of its physical properties over time in the presence of hydrocarbons and formation heat. The ball may be used in methods and apparatus for hydraulically fracturing a subterranean zone in a wellbore. | 07-19-2012 |
20130153220 | EXPANDABLE SEAT ASSEMBLY FOR ISOLATING FRACTURE ZONES IN A WELL - An expandable fracture ball seat assembly for use in wellbore zone fracturing operations functions to permit passage therethrough and exit therefrom of fracture ball plugs of only diameters less than a predetermined magnitude. In a representative form, the seat assembly includes a ring stack disposed within a tubular member and formed from a first expandable ring coaxially sandwiched between a setting ring and a second expandable ring. When an oversized fracture ball plug is forced into the seat assembly it axially compresses the ring stack and reduces the diameter of the first expandable ring and telescopes it into the second expandable ring, with the first expandable ring and the setting ring blocking passage through and exit from the seat. A reverse passage of a suitably large diameter fracture ball plug through the seat assembly axially returns the setting ring and first expandable ring to their original positions. | 06-20-2013 |
20130299199 | SEAT ASSEMBLY WITH COUNTER FOR ISOLATING FRACTURE ZONES IN A WELL - A specially designed rotary indexing system and associated operational methods are incorporated in a downhole control device, representatively a sliding sleeve valve, having an outer tubular member in which an annular plug seat is coaxially disposed. The plug seat is resiliently expandable between a first diameter and a larger second diameter and is illustratively of a circumferentially segmented construction. The rotary indexing system is operative to detect the number of plug members that pass through and diametrically expand the plug seat, and responsively preclude passage of further plug members therethrough when such number reaches a predetermined magnitude. Such predetermined magnitude is correlated to the total rotation of an indexing system counter ring portion rotationally driven by axial camming forces transmitted to the rotary indexing system by successive plug member passage-generated diametrical expansions of the plug seat. | 11-14-2013 |
20150068762 | APPARATUS AND METHODS FOR INHIBITING A SCREEN-OUT CONDITION IN A SUBTERRANEAN WELL FRACTURING OPERATION - A subterranean well fracturing system comprises a downhole well string having installed therein initially closed upstream and downstream sliding sleeve valve assemblies each openable to provide fracing fluid discharge outlets through well string side ports to an associated subterranean fracing zone. To inhibit an undesirable screen-out condition during formation fracturing, specially designed apparatus and methods are operative to sequentially (1) block the downstream valve seat, (2) open the blocked downstream valve seat using pressurized fracing fluid, (3) partially block the upstream valve seat, (4) open the partially blocked upstream valve seat using pressurized fracing fluid, a portion of which is flowed through the partially blocked upstream valve seat, and then (5) unblock the partially blocked upstream valve seat to permit a full flow of pressurized fracing fluid therethrough. In this manner, pressurized fracing fluid is simultaneously delivered to two fracing zones to inhibit a screen-out condition in the well string. | 03-12-2015 |
20150176361 | DOWNHOLE TOOL WITH EXPANDABLE ANNULAR PLUG SEAT ASSEMBLY HAVING CIRCUMFERENTIALLY OVERLAPPING SEAT SEGMENT JOINTS - A tubular downhole tool, representatively a sliding sleeve valve, coaxially supports within its interior an annular plug ball seat formed from a series of rigid, arcuate segments that circumferentially overlap one another in various representatively disclosed manners. The seat is expandable from a diametrically compressed orientation, toward which it is resiliently biased, to a diametrically expanded orientation by a plug ball pumped through the seat. Due to the circumferential segment-to-segment overlap, each segment is blocked by its two circumferentially adjacent segments from being axially separated from the overall seat assembly by operational pressure forces. | 06-25-2015 |
20150191998 | SEAT ASSEMBLY WITH COUNTER FOR ISOLATING FRACTURE ZONES IN A WELL - A specially designed rotary indexing system and associated operational methods are incorporated in a downhole control device, representatively a sliding sleeve valve, having an outer tubular member in which an annular plug seat is coaxially disposed. The plug seat is resiliently expandable between a first diameter and a larger second diameter and is illustratively of a circumferentially segmented construction. The rotary indexing system is operative to detect the number of plug members that pass through and diametrically expand the plug seat, and responsively preclude passage of further plug members therethrough when such number reaches a predetermined magnitude. Such predetermined magnitude is correlated to the total rotation of an indexing system counter ring portion rotationally driven by axial camming forces transmitted to the rotary indexing system by successive plug member passage-generated diametrical expansions of the plug seat. | 07-09-2015 |

20150367255 | METHOD AND APPARATUS FOR LIQUID/SOLID SEPARATION SUCH AS DEWATERING PARTICULATE SOLIDS AND AGITATION LEACHING - Methods and apparatus for liquid/solid separation for use in applications such as dewatering fine particulate solids, and recovery of valuable metals from ore in a leaching process are provided. One application relates to methods of agitation leaching of metals such as gold from gold-bearing feedstock. A slurry is formed in a tank by agitation, and allowed to settle. A filter bed forms to drain the liquid from the tank, and a vertical screen pipe such as a well point addresses the formation of an impervious film on the upper surface of the filter bed. | 12-24-2015 |

20140070006 | MAGNETIC STRIPE READER - The invention relates to a magnetic stripe reader, and more particularly, to systems, devices and methods of directly extracting binary information embedded in a magnetic stripe using simple analog and digital signal processing techniques. Once information stored in the magnetic stripe is extracted as a F-2F waveform by the magnetic stripe reader, peaks, valleys and mid-level transition points between every consecutive peak and valley are detected. A peak-to-peak period and an average time are directly derived to determine whether the corresponding peak-to-peak transition is associated with a binary bit of “1” or “0”. This magnetic stripe reader spares a need for a multi-bit analog-to-digital converter (ADC) and a large memory, and thus, constitutes a simple and self-contained solution that may read out the binary information stored on the magnetic stripe with reduced power consumption and improved cost efficiency. | 03-13-2014 |
