Title: Optical fiber connector disassembling tool
Inventor: NAGASE RYOU
IPC: G02B6/38
Filed: 2004-10-01
Granted: 2009-04-07
Abstract: A disassembling tool includes a holding block having a housing portion for accommodating a plug connector, a slide block, and a handling part for sliding the slide block. The plug connector comprises an outer member and a plug frame and is accommodated in the housing portion of the holding block. When turning a handle of the handling part, the slide block is slidably moved so that projections provided on the slide block release the locking between locking portions of the outer member and locked portions of the plug frame. Following this, contact portions provided on the slide block come into contact with the plug frame so as to push it out of the outer member by a given amount.

Abstract: Methods and apparatus for sealing a safety valve within a tubular that the safety valve is designed to be landed and set in are disclosed. The valve includes a seal assembly having a seal on the valve that is acted on by a first piston disposed on a first side of the seal and/or a second piston disposed on a second side of the seal. Wellbore fluid pressure acts on the first piston when the valve is closed, thereby moving the first piston to force the seal into sealing contact with an inside surface of the tubular. When the safety valve is actuated open, fluid pressure from a control line acts on the second piston and moves the second piston to force the seal into sealing contact with the inside surface of the tubular. The seal may include a plurality of chevron seals on each side of a sealing element.

Title: Thermal imaging method to detect subsurface objects
Inventor: DEL GRANDE NANCY K
IPC: G01J5/00
Filed: 2004-01-30
Granted: 2012-10-16
Abstract: A thermal imaging method to detect heat flows from naturally-heated subsurface objects. The method uniquely combines precise, emissivity-corrected temperature maps, thermal inertia maps, temperature simulations, and automatic target recognition to display clear, clutter-free, three-dimensional images of contained hollow objects or structures, at depths to 20 times their diameter. Temperature scans are corrected using two different infrared bands.  Co-registered object-site temperature scans image daily and seasonal temperature-spread differences, which vary inversely as the object's and surrounding host material's thermal inertias. Thermal inertial (resistance to temperature change) is the square root of the product (k.rho.C), for thermal conductivity, k, density, .rho. and heat capacity, C.
