Patent GB-2249138-A (GB)
Title: Valve actuator
Inventor: YOUNG TERRY GLENN
IPC: E21B29/08
Filed: 1991-09-19
Abstract: The invention is a valve actuator, or a booster module for an existing valve actuator, that provides an incremental force to the valve stem (18) at a position close to valve closure. The force is stored in a spring (62) which is held in the compressed position by a collet (48). Upon sufficient movement of the valve actuator stem (18) in the direction towards valve closure, the collet (48) which had previously held the spring (62) in a compressed position drops into recess (36) on shaft (40) so as to be movable into housing extension (38), allow spring (12) to expand and transmit the force of spring (12) directly to shaft (40). The spring (62) is oriented in a direction substantially parallel to the valve stem (18) so that substantially all of its retained energy is transmitted directly to the valve stem (18) through the collet (48). The actuator is described operating a gatevalve in a well pipe, the gate valve also cutting a wire line during closure. <IMAGE>

A circuit for overlaying information on the computer image includes a line buffer 34 for storing overlay information of no more than a single scan line in length, apparatus for providing individual lines of overlay information from the frame buffer 31 to the line buffer 34, apparatus for determining when a scan line of information and an overlay coincide, and apparatus for using the overlay information to modify the output image at positions where an overlay and an image coincide.   By storing overlay information in the frame buffer the invention dispenses with the relatively expensive overlay memory (14, fig 1). <IMAGE>
Patent GB-2251948-A (GB)
Title: System for measuring two variable quantities
Inventor: SHARPE BRIAN ALLAN JOHN
IPC: G01D3/02
Filed: 1992-01-09
Abstract: First and second variable quantities, e.g. pressure and temperature of an aircraft tyre, where the value of the first variable quantity is affected by changes in the value of the second variable quantity, are measured by a system including a sensor 20 having a resistive bridge 21. First and second signals output due to imbalance and change in overall resistance of the bridge under the action of the respective first and second variable quantities are input to an electronics module 22. An application specific integrated circuit (ASIC) 46 carried by a printed circuit board (PCB) 23 processes the first and second signals with calibrated values held in an EEPROM 45 carried by a PCB 24 of the module 22, and outputs signals representative of the corrected true value of the first variable quantity and of the value of the second variable quantity. An advantage of the system is that power is supplied to the system and data measurements are output by the system over one pair of wires which is not possible if two sensors, one for each variable quantity, are used. The temperature values are thus emitted as independent signals and also used for temperature correction of the pressure values. The temperature correction uses a curve fitting method. The first variable may alternatively be load or torque. <IMAGE>

Title: Monitoring drilling operations.
Inventor: HOLBROOK PHILIP
IPC: E21B44/00
Filed: 1993-04-01
Abstract: Methods for controlling the usage of well drill bits and other aspects of well drilling plans are described. At least a portion of a given well is drilled with a given drill bit 10. An abrasive-wear-affecting variable (drilling strength) for the lithology which has been most recently drilled with the bit is continually evaluated. The current abrasive wear of the bit by the total lithology which has been drilled thereby is continually calculated, based on the abrasive-wear-affecting variable. Continued use or retirement of the bit is controlled in accord with the wear calculation. Relative pore pressure at the current site of the drill bit is a useful by-product which can be independently used to control other aspects of the well drilling plan, e.g. mud weight and the selling of casing. <IMAGE>

Title: Crosswell seismic data simulation using Fermat's principle
Inventor: BLAKESLEE SAMUEL N
IPC: G01V1/42
Filed: 1994-02-11
Abstract: A method for simulating crosswell seismic data between first and second spaced apart wells (A, B) is disclosed. According to the invention, a surface seismic source (S) is used to generate a seismic signal at a location on the surface of the earth substantially in line with, but not between, the wells and closer to the first well (A) than to the second well (B). A plurality of downhole seismic receivers (a1-an) are located in the first well (A) and at least one downhole seismic receiver (bk) is located in the second well (B). The actual arrival time of the seismic signal at each of the first well and second well seismic receivers (a1-an, b1-bn) is recorded. For each second well seismic receiver (bk) the actual arrival time is then compared to an estimate of the seismic signal travel time calculated on the basis of an assumed interwell seismic velocity field. If the estimate of the seismic signal travel time is not equal to the actual arrival time for each second well seismic receiver (bk), the assumed interwell seismic velocity field is modified and the calculation is repeated. In this manner, the actual interwell seismic velocity field can be determined. The actual seismic raypath is taken to be that having the minimum travel time, in accordance with Fermat's principle. <IMAGE>
