20090047093 | THREAD LOCKING/PREVAILING TORQUE FASTENER AND FASTENER ASSEMBLY - A thread locking fastener assembly comprising a nut anchor defining an internal thread having a longitudinal axis, a leading face and a trailing face, the internal thread, in axial section, having a profile which is symmetric about a first imaginary line extending radially out from the axis, and a fastener shank having an external thread with a longitudinal axis, a leading face and trailing face, the external thread being received in said internal thread so that said axes are substantially coincident. The external thread, in axial section, has a profile with a radially inner base zone which is symmetric about a second imaginary line extending radially from the shank axis and a radially outer deflectable addendum which is not symmetric about that line so that the addendum prevents axial centralization of the external thread profile in the internal thread profile unless a sufficient axial force is applied to the shank to deflect the addendum. | 02-19-2009 |
20090047095 | THREAD FORMING FASTENER - A thread forming fastener for threading into a nut anchor of a pliable material wherein there is produced during the driving of the fastener a combination of forces that encourages the nut anchor material to flow smoothly and to develop a mating thread in the nut anchor that minimizes stress cracking and radial hoop stress as the mating thread is being formed. The fastener comprises a drive head and a shank extending from the head and having a longitudinal axis, the shank including a core and a thread having a selected axial pitch, a selected thread height and a profile which in axial cross-section includes a leading face, a trailing face and a tip. The leading face is composed of a radially inner concave portion having a first radius and which transitions smoothly to a radially outer convex portion having a second radius, the transition occurring at a point on the common tangent to those portions. The trailing face is composed of a radially inner linear portion which transitions at a selected transition location to a radially outer convex portion having a third radius. The profile also includes a convex blending portion having a fourth radius which blends together the radially outer leading and trailing face portions at the tip. The thread profile produces force vectors during assembly with the nut anchor that provide enhanced mating thread strength and improved resistance to nut anchor thread breakdown. | 02-19-2009 |

20140265512 | HEIGHT ADJUSTMENT MECHANISM SUITABLE FOR A FOOTRING - A mechanism for vertically adjusting a component on a shaft has a collet sleeve riding on the shaft. A spiral track of the component's hub receives a radially outwardly projecting pin on the collet sleeve. The outer surface of the collet sleeve and the inner surface of the hub are tapered so that the hub can rotated one direction to advance the hub on the collet sleeve and compress the collet sleeve onto the shaft to frictionally lock the collet sleeve to the shaft. Because the hub is joined to the collet sleeve by the pin, this also locks the vertical position of the component. Conversely, the hub can be oppositely rotated to release the compression of the collet sleeve so that the collet sleeve, and therefore the vertical component, is slidable on the shaft. | 09-18-2014 |

20090057743 | Integrated Circuit Including Structures Arranged at Different Densities and Method of Forming the Same - A method of forming an integrated circuit includes forming first structures in a first portion of the integrated circuit and forming second structures, which are arranged more densely than the first structures, in a second portion. The first and second structures are defined by lithography processes using photomasks. At least one of the photomasks includes both openings in a first region for supporting the definition of the first structures and openings in a second region for supporting the definition of the second structures. | 03-05-2009 |

20080276401 | Windshield Wiper Assembly with Unitary Arm and Post - A windshield wiper assembly is provided having a unitary wiper arm and post, and a mechanical linkage for receiving the post and moving the arm. The post has a breakaway feature for breaking the post in response to impact. The wiper includes a head partially containing a center post and a button biased with a spring and connected to the center post for releasing the post from the linkage. The post and linkage include a captive ball and mating groove that are mutually engageable for securing the post to the linkage. Alternately, the post has a quick-connect end having a groove and the linkage has a receiving portion with a retractable collar and captive ball bearings. A vehicle is also provided including a windshield, a windshield wiper having a post, a wiper motor, and a mechanical linkage having an opening for receiving the post and powering the wiper. | 11-13-2008 |

20130294194 | METHOD AND APPARATUS FOR SEA CURRENT AIDED, ENHANCED AZIMUTH SEISMIC DATA ACQUISITION - A system of designing and acquiring 3D marine seismic surveys such that the prevailing sea current is parallel or orthogonal to a major axis of the area to be surveyed. By steering the vessel and towed seismic source and receiver arrays through the water, heading into the sea current at some significant angle away from the sea current direction, then the resultant movement of the seismic source and receiver arrays will result in a much richer sampling and measurement of the earth's sub-surface by virtue of increasing the range of source-to-receiver azimuths available. By adopting this method, the final 3D seismic image of the subsurface will be more accurate and will be correctly focussed. Also line change times may be reduced significantly and the overall carbon footprint of the seismic survey may be lessened. | 11-07-2013 |
