20130278117 | SYSTEM AND METHOD FOR ENHANCED MAGNET WIRE INSULATION - A system and method for enhanced magnet wire insulation is described. The system of the invention provides an enhanced insulation for magnet wire that is capable of withstanding high temperatures and provides a seal against water that is needed in electric submersible pump (ESP) applications. The enhanced insulation of the system of the invention provides the dielectric advantages of polyimide tape, such as Kapton tape, while also including the advantages of organic polymer thermoplastic insulation that prevents the delaminating at high temperatures that may occur in pumping applications using a variety of electrical submersible motors. | 10-24-2013 |
20140334953 | APPARATUS, SYSTEM AND METHOD FOR SEALING SUBMERSIBLE PUMP ASSEMBLIES - An apparatus, system and method for sealing an electrical submersible pump assembly are described. An electric submersible pump (ESP) system for pumping solid-laden fluid comprises a thrust chamber of an ESP seal section, the thrust chamber sealed from well fluid on a downstream side by a stationary sand barrier and on an upstream side by a mechanical seal, the thrust chamber further comprising, a rotatable shaft extending axially through the thrust chamber, a head tubularly encasing the thrust chamber and threadedly coupled to a centrifugal pump intake, and a diamond-coated hydrodynamic bearing set inside the thrust chamber, wherein well fluid enters and exits the chamber through cross-drilled apertures in the head of the chamber, and wherein the well fluid forms a hydrodynamic film between the bearing set. | 11-13-2014 |

20090047156 | INSULATED BEARINGS FOR DOWNHOLE MOTORS - A submersible pumping system for use downhole, wherein the system includes a pump, a pump motor, a seal section, a shaft coupling the pump motor to the pump, a bearing assembly for axially retaining the shaft in place, and an electrical insulator for electrically isolating the pump bearing assembly from electrical current leaking from the motor and through the shaft. The electrical insulator can be made from polyetheretherketone, polyimide, polyketone, and mixtures thereof. | 02-19-2009 |
20110012473 | END COIL TIE DOWNS - A submersible electric pump motor comprises an unvarnished stator structure having stator windings formed of conductors. The stator windings form end coils at each end of the stator for each phase. The end coils are tied to three arc-shaped, metal segments, each having an opening and positioned circumferentially within a circumferential groove. The metal segments are welded to the interior of the housing to provide a rigid surface. High temperature strings are wound through the openings in each metal segment and around the end coils for each phase to tie each end coil of that phase to that metal segment. This prevents the end coils of each phase from twisting during startup, sliding into the slots, and moving inwards towards a rotating rotor. | 01-20-2011 |
20120257985 | Torque Transmitting Rings for Sleeves in Electrical Submersible Pumps - An electrical submersible pump assembly has a motor module coupled to a centrifugal pump module by a seal section module. A shaft assembly extends through each of the modules for causing the motor module to rotate the pump module. At least one of the modules has a sleeve extending around the shaft that is of a harder material than the shaft. A torque transmitting ring is deformed between an inner diameter of the sleeve and an exterior portion of the shaft. The inner diameter of the sleeve is a continuous cylindrical surface free of any torque transmitting shoulders. Friction created by the torque transmitting ring transmits the entire rotational force from the shaft to the sleeve. | 10-11-2012 |

20150176617 | Energy Recapture System for Hydraulic Elevators - In a method of driving a hydraulic system, a contracting force is applied to a hydraulic actuator, thereby causing hydraulic fluid from the hydraulic actuator to flow through a first hydraulic pump motor into a first accumulator, thereby causing the first hydraulic pump motor to apply rotational energy to a shaft. The rotational energy from the shaft is applied to a second hydraulic pump motor, thereby causing hydraulic fluid to be pumped from a second accumulator to a third accumulator so as to store energy in the third accumulator. Once energy is stored in the third accumulator, the second hydraulic pump motor is driven with hydraulic fluid stored in the third accumulator so as to apply rotational energy to the shaft, thereby driving the first hydraulic pump motor to pump hydraulic fluid from the first accumulator to the hydraulic actuator, thereby applying an expanding force to the hydraulic actuator. | 06-25-2015 |

20080226691 | BONE CEMENT COMPOSITIONS HAVING FIBER-REINFORCEMENT AND/OR INCREASED FLOWABILITY - The present invention relates in general to implantable compositions, and method for preparing same, containing a calcium salt-containing component, optionally demineralized bone, a plurality of discrete fibers, optionally a flow additive, and optionally continuous reinforcing fibers or an array of organized fibers in the form of mesh. Advantageously, the discrete fibers have a specific aspect ratio (length/diameter) from about 50:1 to about 1000:1. The addition of a small amount of discrete fibers and/or the continuous reinforcing fibers or fiber mesh can cause drastic increases in certain mechanical properties including flexural strength, flexural toughness, and/or screw pullout strength. | 09-18-2008 |
