20120151663 | SPORTING HELMET - A sports helmet includes recessed insert surfaces on its exterior to accommodate shock absorbing inserts disposed therein. The helmet may include, for example, five recessed insert surfaces, a front recessed surface, a top recessed surface, a rear recessed surface, and two side recessed surfaces. The inserts may be disposed into the recessed surfaces to create a substantially uniform outer helmet shape. A uniform finish may cover the exterior of the helmet. The shock absorbing inserts, when used on a person receiving a force to the helmet's insert, will absorb at least a portion of the force, limiting the force's impact on the wearer's brain. The helmet may, for example, help prevent concussions and other brain injuries in sport participants. | 06-21-2012 |

20140144695 | Systems and Methods for Coupling a Power Cable to a Downhole Motor Using a Penetrator - Systems and methods for providing power to downhole equipment, where an electrical penetrator is installed through the housing of the equipment to provide a high pressure seal between the interior and exterior of the equipment's housing. In one embodiment, the body of the electrical penetrator includes a substantially rigid outer body, an electrically insulating inner body positioned within the outer body, and a set of electrical conductors that extend through the electrically insulating (e.g., glass or ceramic) inner body. Each of the conductors extends through the penetrator body. The inner body is sealed against both the conductors and the outer body by bonding them together, for example. The ends of the conductors which extend into the housing are connected to the motor or other equipment, while the ends of the conductors which to the exterior of the housing are connected to a power cable. | 05-29-2014 |

20130154431 | Systems and Methods for Wire Containment Within an Electric Motor - Systems and methods for the construction of electric motors, where expandable material is inserted into the slots in which magnet wires are positioned and expanded in the slots to mechanically restrain the wires. One embodiment comprises a downhole electric motor such as might be used in an electric submersible pump (ESP) system. The motor has a stator with multiple slots in which magnet wires are positioned. A slot liner is positioned in each slot and an expansion pad is positioned in each slot between the slot liner and the slot wall nearest the bore of the stator. The wires are positioned inside the slot liner. When the motor is almost completely assembled, it is filled with oil. Some of the oil is absorbed by the expansion pads, which then expand to fill the unoccupied volume in the slots, thereby restraining the movement of the wires within the slots. | 06-20-2013 |
