Title: Method and apparatus for demodulating signals in a well logging while drilling system
IPC: H03L7/10
Filed: 1979-02-27
Abstract: In apparatus for obtaining sub- surface measurements during drilling in a fluid-filled borehole digital data representative of downhole measurements are PSK modulated by momentarily unidirectionally changing the frequency of an acoustic carrier signal. An uphole receiving subsystem converts the modulated acoustic carrier waves to electronic signals and includes a bandpass filter (110) which has its centre frequency offset from the nominal carrier frequency in the direction of the unidirectional frequency change applied during modulation, and which may be skewed in the same direction as the offset. The output signal from the filter (110) is coupled to a phase-locked loop (120) which locks onto the carrier of the received signal, and provides timing signals for the demodulation. The phase-locked loop (120) includes a variable bandwidth filter (300), and a controller (205A) to change the bandwidth of the filter (300) as a function of the input signal. The signal applied to the control terminal of the VCO (204) of the loop is compensated as a function of transitions in the received signal to account for the difference, arising from the unidirectional nature of the carrier modulation, between the nominal frequency of the carrier and the average frequency of the received signal. Capacitors in the variable filter (300) are precharged to appropriate voltages to prevent loss of phase- lock during switching between different loopwidths. <IMAGE>
Patent GB-2020458-A (GB)
Title: Improvements in or relating to array processors
IPC: G06F15/80
Filed: 1979-03-13
Abstract: An array processor consisting of a plurality of modules connected together in rows and columns. Each module has at least one special terminal which, as well as providing a connection for transfer of data between adjacent modules, also provides an output which is combined with similar signals from the other modules in the same row, to form a row response signal. Alternate modules in each row are rotated by 180 DEG with respect to each other, so that the special terminals on adjacent modules are connected in pairs. This reduces the complexity of the circuits for forming the row response signals (from gates 81) by combining the module outputs by wired AND/OR logic. <IMAGE>

Patent GB-2019054-A (GB)
Title: A Portable Time-Code Receiver Clock
IPC: G04R20/10
Filed: 1979-04-24
Abstract: A portable clock comprises a superhetrodyne receiver 10 for receiving and detecting a transmitted time signal (such as the 60 kHz MSF slow-code signal) and a pre-settable digital clock 14 driving a display 15. Time and date decoders 12 and 13 decode the detected signal for pre- setting the clock 14 to accord with the transmitted time signal. A single crystal-controlled oscillator 11 supplies a timing reference to the decoders 12 and 13, and serves as a time-base for the pre-settable clock. Moreover, the oscillator 11 serves as the local oscillator for mixing with the receive r.f. signal in the superhetrodyne receiver 10. An error-detecting circuit (Fig 3 not shown) may serve to check that there is a minimum period of substantially no carrier of the received time signal every second, but in the absence of such a minimum period presetting is inhibited. The crystal- controlled oscillator 11 may also serve as a timing reference for such an error-detecting circuit. <IMAGE>

Patent GB-2521089-A (GB)
Title: Radar tracking systems
Inventor: JONES MICHAEL ARTHER
IPC: G01S13/68
Filed: 1979-06-07
Abstract: A radar target tracking system for an active or semi-active missile subject to a jamming source initially operates in a home-on-jam mode. After a short interval the mode reverts to a search mode for a passive target which, if found, switches the mode to track the passive target. If no passive target is found within a limited period an assessment is made of the jammer range by comparing the initial and current jamming signal strength. If the jamming source is within missile range the missile continues to track it, locking out the normal search mode.

Filed: 1979-10-10
Abstract: Methods and apparatus are described for correlatively matching, recording, and displaying, two or more sets of logging data measurements with respect to the borehole depth at which they were generated, and independent of their historical or real-time character. In a particular embodiment of the invention, measurements from each set of data derived or sampled at correlative depths are adjacently displayed in graphical form during a logging operation. The depth offset between the measurements is visually or automatically detected, and in response thereto, the subsequent correlation of other selected measurements and depths at which subsequent measurements are derived are thereby adjusted for further processing, display and recording.

Title: Navigational Instruments
IPC: G01C21/16
Filed: 1980-05-22
Abstract: A navigational instrument for land vehicles comprises inertial rotation-measuring sensors (20,22,24), linear accelerometers (42,44) and a speed sensor (52), all responsive to vehicle movements. The inertial signals are computed and transformed from a vehicle-fixed coordinate system into an earth-fixed system. Gravity components of acceleration are added to the accelerometer signals to provide translation acceleration signals and integrated to provide inertia speed signals. An optimizing filter (76) responsive to the inertial and the speed signals provides vehicle-fixed optimized speed signals which are transformed into earth-fixed speed signals. A computer (74) provides vehicle position signals from the transformed speed signals. Estimates of errors in speed and acceleration are determined. <IMAGE>

Patent GB-2062865-A (GB)
Title: Fluid density transducer
IPC: G01N9/00
Filed: 1980-10-22
Abstract: A fluid density transducer having a vibrating tube 16 for containing the fluid and excitation/pick-up transducers 30, 32, utilizes an elliptical tube 16, having a small degree of ellipticity, to compensate for the variation in the natural frequency of vibration, resulting from a variation in the fluid pressure, i.e a rise in fluid pressure tending to lower the frequency produces a more circular and hence stiffer tube cross-section tending to increase the frequency. A sealed evacuated chamber 36, formed by connecting together cylindrical nodal masses 24 and 26 using a flexible coupling 28, is used to enclose the vibrating tube 16, thus avoiding contaminating, and thereby affecting the calibration of, the tube 16. The tube is supported at each end by a spring plate 12 fixed around its outer periphery to a collar 10 and around its inner periphery to an end-plate 25 of the nodal mass 24 or 26. This provides rigid transverse support and allows use of the transducer in any orientation while accommodating small axial movements of the tube at either end. <IMAGE>

Title: Rock bolting
IPC: E21D21/00
Filed: 1981-02-04
Abstract: A rock bolt (Fig. 1) is in the form of a pipe (11), which is spaced within a borehole (10) of greater diameter than the outer diameter of the pipe. Chemical anchoring material, for example a two-component adhesive, is pumped into the end of the pipe at the face (10a) of the working so as to pass along the inside of the pipe and at the inner end of the pipe to move outwards (10b) and back along the length of the pipe to fill the space between the pipe and the borehole. The anchoring material may be a two- component adhesive, and the components may be mixed by a pipe- like mixer(13) at the outer end (11a) of the pipe and having fixed guide walls (15) for causing a mixing motion of the components. For keeping the rock bolt pipe equally spaced from the wall of the bore hole before chemical anchoring, the pipe may have coil springs (20, 30) increasing in diameter along the length of the pipe. Fingered gripping means may be mounted within, to only partially obstructed, the inner end 11b of the pipe for gripping the wall of the borehole. <IMAGE>
