Downhole tool adapted for telemetry
First Claim
1. An extensible downhole tool, comprising:
- an elongate tube comprising box end and pin end tool joints;
the elongate tube further comprising at least one transmission ring connected to another transmission ring, by means of an extensible transmission line;
wherein when the tool is connected to another tool having similarly disposed rings, the rings transmit an electronic signal from one tool to another.

Abstract
A cycleable downhole tool such as a Jar, a hydraulic hammer, and a shock absorber adapted for telemetry. This invention applies to other tools where the active components of the tool are displaced when the tool is rotationally or translationally cycled. The invention consists of inductive or contact transmission rings that are connected by an extensible conductor. The extensible conductor permits the transmission of the signal before, after, and during the cycling of the tool. The signal may be continuous or intermittent during cycling. The invention also applies to downhole tools that do not cycle, but in operation are under such stress that an extensible conductor is beneficial. The extensible conductor may also consist of an extensible portion and a fixed portion. The extensible conductor also features clamps that maintain the conductor under stresses greater than that seen by the tool, and seals that are capable of protecting against downhole pressure and contamination.
