Abstract: Inductive coupler assemblies for controlling the stray magnetic fields of an inductive coupler to reduce the associated losses are disclosed. This results in reduced attenuation (increased efficiency) of the inductive coupler even in the presence of gaps. The assembly includes an inductive coupler having a housing, a biasing element, and a retention mechanism. The assembly further includes a wire surrounded by a ring of flux channel material disposed in the housing. In some embodiments, the retention mechanism is adapted for removal of the inductive coupler from a pipe joint end. The biasing element may be a circumferential spring disposed between the housing and the pipe joint end. The retention mechanism may be a retention snap ring, press fit, or threaded, to removably couple the housing to the pipe joint end.

Abstract: A transducer device includes an annular housing having a base wall adjoining a pair of annular side walls. The base and side walls define an annular groove. An access port and at least one strain relief opening are formed in the base wall. The at least one strain relief opening is spaced apart from the access port. A conductor is disposed in the annular groove.

Abstract: An apparatus for retaining and tensioning an end of a transmission line includes a nut element having internal threads configured to engage an externally threaded transmission line, such as an externally threaded coaxial cable, thereby retaining an end of the transmission line. The internal threads may form a passageway extending from a first end of the nut element to a second end of the nut element. This passageway may allow a transmission line to pass through the nut element. A socket may be incorporated into one end of the nut element to enable a tool to apply torque thereto. A corresponding method is also disclosed.
