20090107668 | MULTI-FUNCTION COMPLETION TOOL - A multi-functional completion tool which may be lowered into a wellbore coupled to a length of tubing, and then utilized to test various lengths of the tubing at pressure. The tool may also function as a positive plug and may also be used to set the packer, and is also useable as a tubing self-filling tool. Various retention elements are disposed within the tool and configured to release at predetermined pressures, or within predetermined ranges of pressure, thereby transforming the tool from a first configuration to a second configuration depending on the desired function. The tool may also contain a pressure-regulating assembly for regulating the differential pressure across the assembly. The tool may also include an indicator assembly for confirming that the tool has entered a plugging configuration, typically by altering a pressure within the tubing, such alteration being detectible at a surface location. | 04-30-2009 |
20100200225 | MULTI-FUNCTIONAL COMPLETION TOOL - A multi-functional completion tool which may be lowered into a wellbore coupled to a length of tubing, and then utilized to test various lengths of the tubing at pressure. The tool may also function as a positive plug, may be used to set a packer, and is also useable as a tubing self-filling tool. Various retention elements are disposed within the tool and configured to release at predetermined pressures, or within predetermined ranges of pressure, thereby transforming the tool from a first configuration to a second configuration depending on the desired function. The tool may use a flapper mechanism to regulate passage of fluids through the housing, and a piston and/or flow tube may also be utilized to lock the flapper in an open or closed orientation within the housing. | 08-12-2010 |

20120264551 | HANDLE-DAMPENING LACROSSE STICK - A lacrosse stick for reducing the rebound of a ball caught therein. The head of the lacrosse stick is affixed to a tubular shaft in which a portion of the shaft wall at the top end is omitted on the front side and another portion is omitted on the backside below the first omitted portion. A resilient member is inserted within the shaft extending past the lower omitted portion of the shaft wall. The resilient member fills the omitted areas to seat flush therein. A head having a socket and throat is affixed to top end of the shaft. The socket engages the resilient insert via the omitted portions. When a force is applied, for example, by a ball caught in the pocket, the socket compresses the resilient member from the front and the throat from the back allowing the head to rotate backward, dissipating some of the energy and reducing rebound. | 10-18-2012 |
20130029792 | LACROSSE STICK WITH REINFORCED INTERCONNECTION BETWEEN HANDLE AND HEAD - A lacrosse stick with an elongate tubular handle, a plastic head and an improved connection assembly between the handle and head, the connection assembly including an insert inside the handle and straddling at least two opposing walls, at least one screw threaded through the insert and through the opposing walls of the handle to compress the insert between the walls of said handle. The threaded engagement of the screw through the walls and insert sandwich the latter, maintaining a constant compressive force against the laterally enlarged heads and against the interior walls of the handle. This avoids loosening and/or dislodgement as a result of impact or vibration, and resists the threads of the screw stripping either the walls or the insert as a result of torque or other stress. A unitary sleeve insert, a one-piece straddle post embodiment, and a two-piece post embodiment are herein shown and described. | 01-31-2013 |
20130244816 | HANDLE-DAMPENING LACROSSE STICK - A lacrosse stick for reducing the rebound of a ball caught therein. The head of the lacrosse stick has a socket for receiving the shaft, and incorporates one or a plurality of flexible elastomer pads within or as part of the handle or socket, where the head and handle meet, to damp impact and rebound. The flexibility of the damping pads produces a “give” that minimizes the rebound of a pocket after being impacted by a ball. This pocket dampening limits the movement of the ball and makes the ball easier to control and to retain in the pocket. The precise location of the dampening material on the lacrosse head may be varied to control the degree of pocket “give” in response to, for example, the force on the pocket created by a ball impacting the pocket during a catch or swinging in the pocket during cradling. | 09-19-2013 |
20140235377 | SHAFT LOCK FOR INTERCONNECTION BETWEEN LACROSSE STICK HANDLE AND HEAD - A shaft lock for interconnection of an elongate tubular lacrosse handle and a plastic lacrosse head. The shaft lock comprises an elastomeric insert compression-fitted inside the handle. The insert has a compressible body portion which, in an uncompressed form generally conforms to the interior walls of the handle and is defined by a plurality of co-planar ribs that span the interior walls of the handle. A hard screw-anchor is embedded within the elastomer insert, and the insert is anchored inside the handle by at least one screw threaded through the handle into the screw-anchor from top-to-bottom, the screw(s) engaging the screw anchor and compressing it against the elastomeric insert. The threaded engagement of the screw(s) through the wall of the handle and into the screw-anchor compresses the elastomeric insert, maintaining a constant tension against the screw(s) and against the interior walls of the handle. This avoids loosening and/or dislodgement as a result of impact or vibration, and resists the threads of the screw from stripping either the handle wall(s) or the insert as a result of torque or other stress. | 08-21-2014 |
20150202521 | STITCHLESS DORSAL PADDING FOR PROTECTIVE SPORTS GLOVES AND OTHER PROTECTIVE GEAR - A protective glove having a unitary dorsal panel formed from an inner scrim material and a plurality of protective elements molded directly to an exterior surface of the inner scrim. The plurality of protective elements are formed in an array of discrete islands each separated by zero-elevation interstitial spaces. The unitary dorsal panel is sewn or otherwise attached circumferentially to the palmer sections of the glove. This array provides increased protection to the user's fingers, hands, wrists, and lower forearms while maintaining flexibility and tactile feel on both palmar and dorsal sides of the glove, increasing flexibility where needed without compromising protection. | 07-23-2015 |
