Title: Method for improving drilling depth measurements
Inventor: HUTCHINSON MARK W
IPC: E21B47/04
Filed: 2003-04-03
Granted: 2008-06-17
Abstract: A method for determining a depth of a wellbore is disclosed. The method includes determining change in a suspended weight of a drill string from a first time to a second time. A change in axial position of the upper portion of the drill string between the first time and the second time is determined.  An expected amount of drill string compression related to the change in suspended weight is corrected for movement of a lower portion of the drill string between the first time and the second time. A position of the lower portion of the drill string is calculated from the change in axial position and the corrected amount of drill string compression. In one embodiment, the correcting includes estimating drill bit movement by determining an axial motion of the drill string at the earth's surface between two times having a same suspended weight of the drill string.

Abstract: The Quasiturbine (Qurbine in short) uses a rotor arrangement peripherally supported by four rolling carriages, the carriages taking the pivoting blade pressure-load, of the blades forming the rotor, and transferring the load to theopposite contoured housing wall. The present invention discloses a central, annular, rotor support for the geometry defined by the pivoting blades and associated wheelbearings, while still maintaining the important center-free engine characteristic. The pressure-load on each pivoting blade is taken either by its own set of wheel-bearings rolling on annular tracks attached to the central area of lateral side covers forming part of the casing, or is cancelled out in symmetrically pressurized fluid energy converter mode through the central holding action of annular power sleeves. This central, annular, rotor support could generally apply to all the family of Quasiturbine rotor arrangements and particularly to the limit case here considered, where the previous carriage design is replaced by a cylindrical pivoting blade joint as developed in the present patent, and for which an efficient solution of the five bodies rotary engine sealing problem is given.

Abstract: An interlock for a vehicle platform lift meets the Federal Motor Vehicle Safety Standards (FMVSS 403) effective in late 2004 with minimum modification of vehicle electronic control arrangements. The interlock prevents forward and rearward mobility of vehicles unless the platform lift is stowed. The interlock operates to prevent accidental release but does not affect vehicle movement when the platform lift is stowed. Operation of the lift is allowed by placing the transmission in park or by placing the transmission in neutral and actuating the parking brake. A vehicle body computer controls operation when the vehicle is running. A bypass enable relay allows use when the vehicle's engine is not running.
