Title: Method and apparatus for demodulating  signals in logging while drilling system
Inventor: SCHROEDER GENE F
IPC: H03L7/10
Filed: 1979-02-26
Granted: 1982-07-20
Abstract: ABSTRACT OF THE DISCLOSURE             The disclosure is applicable for use in a logging-while-drilling apparatus for obtaining subsurface measure-ments during drilling in a fluid-filled borehole.  Acoustic carrier waves are generated downhole in the borehole fluid and are PSK modulated in accordance with digital data representative of downhole measurements.  The PSK modulation is obtained by momentarily unidirectionally either decreasing or increasing the frequency of the acoustic carrier signal until either a desired phase lag (for a decrease in frequency) or phase lead (for an increase frequency) is imparted to the acoustic carrier signal.  An uphole receiving subsystem includes transducers for converting the modulated acoustic carrier waves to electronic signals and circuitry for de-modulating the electronic signals to recover the measurement information taken downhole.  A variable loopwidth carrier tracking loop is provided for locking onto the carrier of the received signal.  Timing signals from this tracking loop can then be utilized in demodulating the received signal. the tracking loop as disclosed herein comprises a phase-locked loop which includes an oscillator having a controlled input, error signal generating means for generating an error signal as a function of the phase difference between a signal derived from the oscillator and the input signal.  A variable filter, having a plurality of different bandwidths, couples the output of the error signal generating means to the control input of the oscillator.  A loopwidth controller is coupled to the variable filter and is operative to change the loopwidth of the filter as a function of the input signal.  In the preferred embodiment of the invention, the variable filter of the carrier tracking loop includes a plurality of capacitors which are switchably coupled into and out of operation in the filter under control of the loopwidth control means.  Those of the capacitors which are not currently operational in the filter are precharged so as to prevent loss of lock in the phase-locked loop when switching to another loopwidth.

Abstract: AUTOMATIC LOCOMOTIVE SPEED CONTROL     ABSTRACT OF THE DISCLOSURE          An automatic speed control system for a consist of diesel locomotives conserves fuel by throttling back trailing engines and operating remaining engines at the most efficient throttle position.  A control unit in the lead locomotive is operated by the engineer to command control units in equipped trailing locomotives of the consist.  In the lead locomotive, depressing a "set speed" push button causes a speed memory to store the existing speed of the consist, and a cutout control signal is generated which is trans-mitted to trailing units in serial order, i.e., front to rear, by a single spare trainline wire.  The control signal has two control voltage levels that increase or decrease with deviations of the speed of the consist from the desired speed in memory.  These voltage levels are decoded by each trailing unit and, if power is needed, the engine throttle is set at the most efficient position or, if the locomotive is to be cut out, the throttle is set at a desired minimum position.  The trailing units also cause these voltage levels to drop by a fixed amount (equivalent to a predetermined speed increase) as the control signal is conducted by the trainline wire rearwardly in the consist from each trailing unit to the next succeeding trailing unit.  In this manner, engines are successively throttled (Docket 388) back from the rear of the consist and returned to the higher throttle position from the front to maintain the desired train speed.  A hold mode permits the automatic control system to be tempo-rarily disabled without clearing the speed memory or changing the control signal, and depressing a "resume speed" push button on the lead unit reestab-lishes automatic speed regulation.

Abstract: METHOD OF PRODUCING MINCED FISH MEAT            ABSTRACT     The present invention relates to a method of separating meat from fish in water or in an aqueous solution of alkaline salts, saccharide and/or amino acids.  Hitherto the meat has been separated from the fish in air, such that the freshness of the meat has rapidly deteriorated.  The present invention can prevent such a drawback.  When the boiled fish paste is produced from fish meat which has been prevented from deter-iorating, it is possible to obtain a boiled fish paste of a higher jelly strength; in other words, a paste of a higher quality having a good texture.

Abstract: Christia-1 16.            POWER SUPPLY CIRCUIT FOR A DATA PROCESSOR         Abstract of the Disclosure In order to extend battery life when batteries are used and to conserve energy when commercial power is used, it is highly desirable that power not be applied to a data processor when it is not operating.  A power supply in accordance with the present invention includes a power-up and supply subcircuit (100) that applies power to an associated data processor (500) when a data input circuit (700) is operated to select a particular operation of the processor.  When the processor completes its operation, it provides an output signal to a power-down subcircuit (200) of the power supply which then removes power from the processor.

Abstract: ABSTRACT.         "Method of making planigrams of a three-dimensional object."     In order to make planigrams of a three-dimensional object, the object is irradiated from different directions in order to form a superposition image which consists of separate perspective images, Multiple imaging of the super-position image is realized by means of an imaging matrix, the individual perspective images being superposed in a zone which is situated behind the imaging matrix and in which, for example, a ground glass plate can be arbitrarily positioned for the imaging of layer images. During the superposition of the individual perspective images by means of the associated imaging elements of the imaging matrix, however, artefact images are caused by the transmission of perspective image, by inappropriare imaging elements. These artefact images are suppressed in that on each artefact image a correction perspective image, derived from a perspective image, is superposed via an additional imaging element in order to compensate for the artefact image.

Abstract: 13.     DIGITAL LOOP SYNCHRONIZATION CIRCUIT         Abstract of the Disclosure There is disclosed a digital loop circuit for controlling synchronization around a closed loop communication system.  The control circuit (20) is designed to automatically adjust the delay of the loop to maintain a constant frame bit length without regard to the number of stations connected into the loop.  As stations are added or subtracted from the loop, the system operated to subtract or add delay as necessary. A first in and first out (FIFO) register having a bit capacity equal to the frame size is inserted serially in the loop and a separate clock is used to control the input and the output of the first in and first out register (FIFO). If a unique frame bit is not received in the anticipated position then the clock output skips one count per frame thereby adding delay to the loop.  The loop control circuit operates for situations where the framing bit is on a separate channel and also when the framing bit is on the actual data channel.
