A slot cut in the driven nut and in the surrounding housing allows additional right hand rotation so that a lug is captured on a shoulder to prevent subsequent axial compression of the selective grip assembly, where the tubular grip will be maintained with rotation. By preventing the tool from moving to the “unlocked” position when set down weight from the rig as applied, it can be operated in a variety of common conditions in today's well drilling environments with applied tension or compression as well as rotation in a direction that leaves the lug captured on a ledge adjacent the slot cut in the driven nut. | 2020-11-05 |

The top end of the connector sleeve rotatably impinges on a non-rotating member of the top drive directly, the top drive longitudinal carriage, or a combination of the two. Rotation of the top drive out put shaft will transmit a force to the non-rotating sleeve through seal friction until the top end of the connector sleeve contacts a non-rotating body of the top drive's longitudinal carriage or the top drive directly or both. Upon contact, the non-rotating sleeve will resist the torque aided by the connector sleeve and overcome the seal friction transmitted to the non-rotating sleeve. The top drive and connector move axially in tandem and even have some capability of relative axial movement while resisting further relative rotation while facilitating assembly of the components. | 2020-11-05 |

The outer core casing includes a first flange connection arranged to allow separation of the outer core casing at an axial position of the first flange connection, the first flange connection having a first flange radius, wherein the first flange connection is the connection that is downstream of an axial position defined by the axial midpoint between the mid-span axial location on the trailing edge of the most downstream aerofoil of the first compressor and the mid-span axial location on the leading edge of the most upstream aerofoil of the second compressor, and a front mount arranged to be connected to a pylon. A front mount position ratio of: | 2020-11-05 |
20200347749 | GAS TURBINE ENGINE WITH IMPROVED BENDING RESISTANCE - A gas turbine engine for an aircraft includes: an engine core with: a compressor system including a first, lower pressure, compressor, and a second, higher pressure, compressor; and an outer core casing surrounding the compressor system. The gas turbine engine further includes a fan located upstream of the engine core with a plurality of fan blades and having a fan diameter. The outer core casing includes a first flange connection arranged to allow separation of the outer core casing at an axial position of the first flange connection which has a first flange radius, wherein the first flange connection is downstream of an axial position defined by the axial midpoint between the mid-span axial location on the trailing edge of the most downstream aerofoil of the first compressor and the mid-span axial location on the leading edge of the most upstream aerofoil of the second compressor. | 2020-11-05 |
