20080202751 | Methods and Devices for Forming a Wellbore with Casing - An example of a method for cementing a casing within an earthen formation includes the steps of providing a gripping mechanism connected to a cementing assembly and a top drive; gripping the casing with the gripping mechanism; sealingly engaging the casing with a seal member; moving the casing to a position within the formation; and cementing the casing within the formation while maintaining a gripping and sealing engagement of the casing. The step of cementing may also include the step of remotely releasing a plug into the casing from the cementing assembly. | 08-28-2008 |
20080238117 | Load ring for lifting by elevator, of casing having no upset - A cylindrical ring sized to slide over the box end of an oilfield tubular having a given diameter, has a shoulder at one its ends and a sidewall along its length. The sidewall has a circumferential groove about its interior surface housing a band which can be made tight against the exterior surface of the oilfield tubular by a latch accessible through a slot in the sidewall, and which becomes even tighter if the tubular attempts to escape from the band. In a first orientation, the cylindrical ring is used as a load ring. By turning the cylindrical rings upside down, the cylindrical ring is used as a thread protector for the pin end of the tubular. | 10-02-2008 |
20100206584 | DOWNHOLE TUBULAR CONNECTOR - A hydraulic connector to provide a fluidic connection between a fluid supply and a downhole tubular, the connector comprising: a body; an engagement assembly comprising an extendable portion selectively extendable from the body, the engagement assembly being configured to extend and retract a seal assembly disposed at a distal end of the extendable portion into and from a proximal end of the downhole tubular; and a valve assembly operable between an open position and a closed position, the valve assembly being configured to: allow a fluid to communicate between the fluid supply and the downhole tubular through the seal assembly when in the open position; and prevent fluid communication between the fluid supply and the downhole tubular when in the closed position. | 08-19-2010 |

20120153036 | Scent dispersing apparatus - An animal attractant, such as a liquid scent can be dispersed from a soft-shelled frangible capsule by positioning the capsule in an enclosure and then attaching the enclosure to an arrow. A plunger secured to the enclosure slidably moves inside the enclosure and causes rapture of the capsule upon impact of the plunger with a solid surface. The liquid animal attractant is dispersed through cutouts formed in the enclosure in a fan-like fashion. | 06-21-2012 |
20130123051 | Ammunition Delivery System Arrowhead and Method of Use - A device and method introduces the use of conventional ammunitions to the archery/bow hunting industry. The device achieves stealthy delivery of firearm munitions and increases the firepower of standard arrows resulting in deeper penetration into a target. The device consists generally of a containment housing threaded internally on one end for attachment to a firing pin. A cartridge is loaded into the containment housing until the flange on the cartridge casing abuts an interior shoulder. In an alternate embodiment, the interior of the containment housing further includes an annular retaining tab integrally formed in the interior of the housing containment. The retainer tab separates the cartridge from the firing pin to prevent inadvertent discharge. A safety cap may be included on the containment housing to further protect the device from accidental discharge of the cartridge. | 05-16-2013 |

The device achieves stealthy delivery of firearm munitions and increases the firepower of standard arrows resulting in deeper penetration into a target. The device consists generally of a cylindrical housing threaded internally on one end for attachment to a firing pin. A cartridge is loaded into the housing until the flange on the cartridge casing abuts an interior shoulder. In an alternate embodiment, the interior of the housing further includes an annular retaining tab. The retaining tab separates the cartridge from the firing pin to prevent inadvertent discharge. A cap or nosecone may be included to further protect the device from accidental discharge of the cartridge and to provide aerodynamic advantages. The housing may further include a set of stabilizing vanes. | 08-15-2013 |
