Title: Method of and apparatus for detecting an influx into a well while drilling
Inventor: CODAZZI DANIEL
IPC: E21B47/10
Filed: 1991-06-28
Granted: 1996-10-08
Abstract: Gas influx into a wellborer called a "kick", is detected by different, yet complementary methods during active drilling of the borehole.  The first method is based upon the existence of standing wave patterns generated by pressure oscillations of the drilling rig mud pumps.  Such standing wave patterns form time sequences of maxima and minima as a gas slug moves upwardly in the annulus. The time between such peaks of such oscillations is measured and forms the basis for generation of one kick signal. A continuous increase in the phase between annulus and drill string standing waves forms the basis for another standing wave kick signal.  The second method uses acoustic signals from a downhole source near the bottom of the borehole which are transmitted at different speeds in the annulus mud and in the interior drill string mud, where the annulus mud may be gas cut.  A difference in arrival time between the signals is determined, and if large enough, causes a second kick signal to be generated. A third method may be used where at least two drilling pumps are used i the drilling system.  Such method determines the total travel time, from standpipe to drill string and up the annulus, of a beat frequency pressure wave caused by slightly different frequencies of the two pumps.  An alarm signal is generated if the total travel time is greater than a computed threshold.

Granted: 1995-12-12
Abstract: A method for receiving and processing predetermined signals in paging receiver with a battery save function.          A  first  to  third  predetermined  codes  of  a  batch  are detected.    Then,   if  an  error  occurs  in  a  second predetermined  code  of  a  next  batch,  not  a  second predetermined code of the next batch is searched for but continuously the BCH-decoding is performed with code words in the next batch by the BCH decoding algorithm.  Thus, if a non-error code word is detected in the code words, the second  predetermined  code  in  which  an  error  occurs previously   is   recognized   as   the   normal   second predetermined code and a subsequent address code word is searched   for.    Accordingly,   even   if   the   second predetermined  code  is  missed,   at  the  normal  batch construction, the missed second predetermined code can be compensated by the subsequent code word.

Abstract: Agglomerates having nominal diameters in the range of 40 to  800 micrometers  of  zeolitic  molecular  sieve  particles having a mean particle size of 0.5 to 20 micrometers which are bonded  with  particles  of  generally  spherical  amorphous colloidal-sized silica particles having a nominal diameter of 5 to 80 nanometers are found to have increased adsorption capacity for many molecular species due to the development in the binder of a pore system created by the packing of the silica spheres.  When the molecular sieves employed are highly siliceous and hydrophobic, the agglomerates are ideally suited for   use   in   odor   elimination   applications   in   which unagglomerated molecular sieve particles create dusting and handling problems.

Title: Refrigerator with subcooling flow control valve
Inventor: NELSON WILLIAM G
IPC: F25B49/02

Granted: 1997-02-11
Abstract: A household type refrigerator has a refrigeration system  including a  subcooling flow control  valve placed between the outlet of the condenser and the inlet to the capillary tube.  The subcooling flow control valve utilizes a sealed capsule of refrigerant which operates to open and close a valve to modulate the flow from the condenser to the capillary tube to insure only that a subcooled liquid enters the capillary.  The valve is mounted vertically next to the compressor and has the inlet line to the valve secured in heat conducting contact to the return line to the compressor for faster opening and closing response while the discharge side of the valve has a chamber filled with a plug to minimize the volume of refrigerant remaining between the closed valve and the entrance to the capillary when the compressor is on the off cycle.

Title: Optical transmission system equalizer
Inventor: CHRAPLYVY ANDREW R
IPC: H04B10/294
Filed: 1992-09-17
Granted: 1996-10-01
Abstract: Increasing the capacity of an existing lightwave transmission system can be accomplished by either increasing the bit rate or adding wavelength-multiplexed channels.  Recent advances in erbium-doped fiber amplifier technology make the wavelength division multiplexed option particularly attractive.  Unfortunately, because of nonuniform wavelength-dependent gain profile and saturation characteristic of erbium-doped fiber amplifiers, each channel of a wavelength-multiplexed system will experience a different optical gain which, in turn, can result in an excessive bit-error-rate performance in some channels.  This invention is directed toward processing apparatus which selectively equalizes the optical gain or the optical signal-to-noise ratios of the channels of a wavelength-multiplexed optical transmission system.  The output powers and the signal-to-noise ratios are selectively equalized by adjusting the optical input signal powers.  With this invention, wavelength-multiplexed channels can be added to an existing optical fiber transmission system without requiring new optical components, upgrades or adjustments at intermediate amplifier sites.
