  • Resistance sensing free-point tool
    Patent number: 3934466
    Abstract: An improved free-point measuring system for indicating whether a pipe in a borehole is free or stuck at various locations within the borehole is disclosed. The system employs an improved free-point tool in which is mounted a variable resistor having a wiper arm adapted to be displaced with a movement of the pipe. Displacement of the wiper arm causes a change in the resistance of the variable resistor, and this change is detected by a surface unit provided with balancing and calibrating resistors.
