20120031671 | Drill Bits With Rolling Cone Reamer Sections - A drill bit for drilling a borehole in earthen formations comprises a bit body having a central bit axis, a first end adapted to be connected to a drillstring, and a second end opposite the first end. In addition, the bit comprises a pilot bit extending from the second end of the bit body. Further, the bit comprises a reamer section extending radially from the bit body and axially positioned between the first end of the bit body and the pilot bit. The reamer section comprises a rolling cone cutter rotatably mounted to a journal shaft extending from the bit body. Moreover, the rolling cone cutter has a cone axis of rotation, a backface proximal the bit body, and a nose opposite the backface and distal the bit body. | 02-09-2012 |

20120312603 | OPTIMIZATION OF DRILL BIT CUTTING STRUCTURE - Disclosed is method for designing a fixed cutter drill bit comprising: (a) defining initial primary placement parameters for primary cutter elements; (b) repeatedly: selecting back up placement parameters for back up cutter elements; applying to a simulated formation a bit design having the combination of the defined initial primary placement parameters and the selected back up placement parameters; using the combination in the simulation and generating a value representative of a first design criteria of interest (such as resultant force on a cutter element, total out-of-balance force on the bit, resistance to slip stick, and resistance to bit vibration); comparing the generated value to a first predetermined acceptable value. | 12-13-2012 |

20120046869 | SYSTEM AND METHOD FOR BENT MOTOR CUTTING STRUCTURE ANALYSIS - Techniques for analyzing operation of drill bit in a borehole are disclosed herein. A method for analyzing operation of a drill bit in a borehole includes providing information describing the drill bit and a bent housing coupled to the drill bit. A path of a cutter of the drill bit is determined based on a ratio of a rotational speed of the bent housing to a combined rotational speed of the drill bit and the bent housing. The combined rotational speed is different from the rotation speed of the bent housing. | 02-23-2012 |
20140174827 | Drilling Systems and Fixed Cutter Bits with Adjustable Depth-of-Cut to Control Torque-on-Bit - A drill bit for drilling a borehole in an earthen formation includes a connection member having a pin end. In addition, the drill bit includes a bit body coupled to the connection member and configured to rotate relative to the connection member about a central axis of the bit. The bit body includes a bit face. Further, the drill bit includes a blade extending radially along the bit face. Still further, the drill bit includes a plurality of cutter elements mounted to a cutter-supporting surface of the blade. Moreover, the drill bit includes a depth-of-cut limiting structure slidably disposed in a bore extending axially from the cutter-supporting surface. The depth-of-cut limiting structure is configured to move axially relative to the bit body in response to rotation of the bit body relative to the connection member. | 06-26-2014 |

20140014641 | MELTABLE FUEL WARMER ASSEMBLY | 01-16-2014 |
20140374415 | WAX MELT ASSEMBLY - A wax melt assembly includes a plurality of first wax melts, a plurality of second wax melts and a melt retainer. The first wax melts each have a first property. The second wax melts each have a second property that is different than the first property. The melt retainer includes a first compartment, a second compartment and a retainer body. The first compartment retains the first wax melts. The second compartment retains the second wax melts. The retainer body can have a height that extends from a base to a top of the retainer body and can include a plurality of exterior side walls that extend the height of the retainer body. The retainer body can include a compartment separator that extends between the first compartment and the second compartment. The first compartment can include a first sub-compartment that retains one of the first wax melts, and a second sub-compartment that retains another of the first wax melts. The first wax melt in the first sub-compartment and the first wax melt in the second sub-compartment can be connected to one another. The properties can include scents and/or colors. | 12-25-2014 |
