Title: Programmable memory for an encoding system
Inventor: KATZENSTEIN HENRY S
IPC: H04B5/02
Filed: 1989-03-20
Granted: 1993-04-13
Abstract: PROGRAMMABLE MEMORY FOR AN ENCODING SYSTEM                   Abstract of the Disclosure An identification system includes a reader and a transponder.  The reader initially transmits a pulse to the transponder.  The transponder responds to this pulse by transmitting to the reader a sequence of a particular number (e.g. 10) of signals at a frequency dependent upon the identifying code recorded in the transponder.  The reader then transmits a pulse of an opposite polarity to that previously transmitted.  The transponder responds by generating 10 signals at a second frequency different from the first frequency.  In this way, sequences of pulses alternatively of opposite polarity are transmitted by the reader and sequences of signals at the first and second frequencies are transmitted by the transponder. The reader decodes the sequences of signals at the first and second frequencies, in accordance with the order of the frequencies of such signals, to identify the code at the transponder.  The transponder may have a programmable memory to store the code.  To program the memory with such a code, the reader generates, and transmits to the transponder, sequences of pulses, each sequence coding for a programmable item of information (e.g. binary "1", binary "0" and reset).  Depending upon the individual programmable item, the coded sequences may have pulses of the same polarity or of opposite polarity. At a time related to each such sequence, the reader produces a sequence different from the coded sequence to indicate that pulses coding for a programmable item follow.  The transponder demodulates and decodes the transmitted pulses to recover the identifying code.  This code is then recorded in the programmable memory and is used thereafter to identify the transponder when the reader interrogates the transponder as described above.                       * * * * * * * * *

Abstract: ABSTRACT OF THE DISCLOSURE      A  drill   string  apparatus   for  the  controlled absorption of both axial and torsional forces exhibited on the well string during drilling operations.  The device is adapted to be connected in the drill string above the drilling tool in order to control the forces acting on the bit and to arrange the mean weight on bit for the selected drilling operation.  Generally, the apparatus includes an outer casing coupled at its upper end to the drill string and an inner assembly telescopically received within the outer casing and connected at its lower end to the lower part of the bottom hole assembly or the drilling tool. Rotational torque is transferred from the drill string and outer casing to the inner assembly and drill bit by a series of helical splines.   The mean weight on bit is controlled through  an  interchangeable  pressure  control nozzle mounted at the top of the inner assembly.  Dual pistons with corresponding fluid chambers dampen axial forces while the helical splines decouple the torsional forces from axial vibrations to ensure proper control of the drill bit.  In addition to attenuating vibration in conventional drilling operations,  the present  invention can be utilized in highly deviated holes and in drill strings using coiled tubes.
