Title: Externally mounted radioactivity detector for MWD employing radial inline scintillator and photomultiplier tube
Inventor: MEISNER JAMES EDWARD
IPC: E21B47/01
Filed: 1991-02-25
Abstract: Improved radioactivity well logging by mounting a scintillator 250 and photomultiplier tube 252 in a single case 262 interfacing with a hole extending through a drill collar 89 at the lower end of a drill string so that measurements can be made while drilling. Radioactive sources (when required for well logging) are mounted in cavities which open to the exterior of the drill collar. Light from the scintillator 250 is coupled directly to the aligned photomultiplier tube both of which are mounted in a case extending radially within the drill collar and sealingly engaging an electronics housing within the drill collar and the drill collar wall surrounding the hole. The scintillator is of greater diameter than the photomultiplier tube. A frustoconical light pipe connects the scintillator and the photomultiplier tube, channeling scintillation in the crystal to the photomultiplier to provide an amplified detection capability over that for a scintillator having the same diameter as the photomultiplier tube. <IMAGE>
Patent GB-2249396-A (GB)
Title: Force balance instrument
Inventor: STEWART ROBERT E
IPC: G01L1/08
Filed: 1991-10-03
Abstract: A force balanced instrument, such as an accelerometer, employs a pendulous mass (12) having combined electrostatic pickoff and forcing plates (14, 16) on opposite sides thereof. The plates provide a constant attractive force in successive periods acting alternately on opposing sides of the sensitive element (12). Force balance is achieved by controlling the duty cycle so that the difference in duration between each of the parts of a full cycle is a linear measure of acceleration. Voltage on each of the forcing plates is sensed independently immediately after each is charged with a fixed charging pulse which provides a fixed force level over the duration of the part cycle. The two successive voltage samples are stored, and the difference between them integrated to control the duty cycle of a pulse width modulator (82), which itself controls the duration of application of the alternately directed forces applied by the respective plates (14, 16) to the pendulous mass (12). <IMAGE>

Title: Apparatus for triggering chemically augmented electrical fuses
Inventor: RANJAN RADHAKRISHNAN
IPC: H01H85/46
Filed: 1993-01-14
Abstract: An apparatus for triggering chemical augmented electrical fuses includes a light source 52 which emits a light signal in the form of visible or infrared light energy upon receiving a signal from a control system, trigger signal source or other fuses. The light signal is coupled to a light detector 54 by an optical coupling device such as a fiber optic cable 56. Upon receipt of the light signal, the light detector generates a signal which causes the application of electrical energy to exothermic material in a fuse, thereby detonating the material and causing interruption of current through the triggered fuse. Alternatively, the fuses may be linked mechanically, with a piezoelectric detector responsive to the shock wave from another detonation. <IMAGE>
