Systems, methods, and software described herein facilitate the implementation of discrete machines in a distributed data processing environment. When the auger nose of the modified sonde assembly strikes any of various obstructions on the sidewall that cause it to lose momentum, such as a rock ledge, the momentum of the heavy sonde causes the auger nose assembly to compress, forcing the auger to rotate on the spiral gear. The invention teaches methods of reducing the toxicity of drugs comprising the introduction of ester groups into drugs during the synthesis of the drug. The solenoid further includes a permanent magnet having a second magnetic field, wherein the magnet is located adjacent the armature. In accordance with an embodiment of the instant invention, the system is equipped with a central control unit which monitors system components and provides a warning if a system component is in jeopardy of malfunctioning.
