20130081495 | GEARBOX WITH MULTI-FUNCTION QUILL - A gearbox comprises a multi-function quill. The quill is provided for loading a bearing and limiting brake-releasing movement of a piston of a brake release. | 04-04-2013 |
20140150589 | SYSTEM FOR LUBRICATING INPUT SHAFT SPLINE OF FINAL DRIVE TRANSMISSION - The splines of a connection between a connecting collar and transmission input shaft includes a main lubrication oil passage extending axially through an input gear in alignment with a blind bore provided in a wall of a compartment containing the input gear and a second gear meshed with the input gear and partially immersed in an oil reservoir defined by a lower region of the compartment. An oil capture recess is located in a wall region above the blind bore and adjacent a roller bearing supporting one side of the input gear. A bypass lubrication oil passage connects the capture recess to the blind bore. An oil transfer tube is carried by a sheet metal cup mounted in a circular recess joining the blind bore and has opposite ends positioned in the main lubrication oil passage and the blind bore. The bypass passage bypasses the roller bearing. | 06-05-2014 |
20140151966 | DUAL SEALING ARRANGEMENT FOR FINAL DRIVE GEAR BOX - A final drive transmission includes concentric inner and outer metal face seals at an interface between fixed and rotating housing sections for preventing oil contaminating material from entering the housing. Each face seal includes identical metal face seal rings that are biased into sealing engagement with each by identical frusto-conical elastomeric rings. The metal rings are generally L-shaped in cross section, with the metal rings of the outer face seals being constructed to withstand extreme conditions by making their cross section approximately twice that of the inner metal rings. Together with interface surfaces, the assembled inner and outer face seals define a sealed cavity which contains lubrication oil. A reservoir of oil with an oil level sensor is coupled to the sealed cavity and in this way it is determined whether or not oil is leaking from the cavity so that steps may be taken to avoid a catastrophic failure. | 06-05-2014 |

20150345234 | Apparatus for Handling Tubulars - A tubular handling tool is taught for use as an elevator, comprising one or more slips movably retained by one or more upper and lower rings, wherein the upper and lower rings provide constraint against radial expansion forces. A frame is taught for an elevator comprising one or more upper and lower rings and one or more removable means for connecting the upper and lower rings and attaching the frame to a top drive. A tubular handling tool is taught for use as a top mount spider comprising one or more slips movably retained by one or more upper and lower rings, wherein the upper and lower rings provide constraint against radial expansion forces. A tubular handling tool is taught for use as a flush mount spider comprising one or more slips movably retained on an upper ring and a lower ring. A slip is taught comprising a movable sliphead. | 12-03-2015 |

20120005634 | Control of Critical Dimensions in Optical Imaging Processes for Semiconductor Production by Extracting Imaging Imperfections on the Basis of Imaging Tool Specific Intensity Measurements and Simulations - Variations in critical dimensions of circuit features of sophisticated semiconductor devices may be reduced by efficiently extracting mask and/or imaging tool specific non-uniformities with high spatial resolution by using measured intensity values and simulated intensity values. For example, a tool internal radiation sensor may be used for measuring the intensity of an image of a lithography mask, while a simulated intensity enables eliminating the mask pattern specific intensity contributions. In this manner, high spatial resolution of the corresponding correction map may be obtained without undue effort in terms of man power and measurement tool resources. | 01-05-2012 |
