Abstract:
The present invention provides a ruggedized heavy duty source connector adapted for use on large air guns. The source connector comprises reinforcing fibers in the cable jacket that are anchored to the connector front shell, an external blast shield in place of a rear shell, and a fatigue resistant strain relief overmold.
Abstract:
A seismic cable coupling comprising connector body, a coupling ring is rotatably mounted on the connector body. The coupling ring includes a ring body having a first longitudinal projection and a second longitudinal projection, the first longitudinal projection having an interior surface including a first angled groove, the second longitudinal projection having an exterior surface including a first raised stud. The coupling ring is a hermaphrodite coupling ring that mates with a coupling ring having a substantially identical ring body.
Abstract:
A connection device for cables having an elongated, cylindrical body with first and second ends, a termination interface member attached to each end of the elongated cylindrical body, wherein the elongated, cylindrical body is made of a flexible, cylindrical substrate member extending between the termination interfaces, with a plurality of elongated tension members helically wound about the exterior of the flexible substrate member, the ends of the tension members being attached to respective termination interface members.

Abstract:
A connector is disclosed for joining two cable ends. The connector includes a load transfer plug adapted to couple to a strength member in each end of the cable. A connector insert assembly is coupled to an inner portion of each load transfer plug. Conductor terminals are disposed in corresponding openings of the insert. The terminals protrude from the insert. An alignment sleeve holder is coupled to one of the insert assemblies. The alignment sleeve holder includes alignment sleeves for receiving the protruding terminals. A housing element is sealingly coupled to an exterior of each of the plugs. The housing elements are adapted to coupled to each other and to urge the connector insert assemblies into contact with each other, and to transfer axial load between the plug coupled to each end of the cable. The housing elements have rotational and axial alignment features on corresponding surfaces. The housing elements are adapted to be removed from the plugs without uncoupling the cable from the plug.
Abstract:
A plug ejector comprises a solenoid incorporated into an electrical plug. An adapter plugs into a wall socket and presents an adapter socket for receiving the plug. Upon activation by a remote switch, the solenoid projects its armature to react against the adapter socket to eject the plug. The plug may be incorporated into an appliance cord, or an extension cord. The plug may incorporate a GFI protector, or a vibration sensor. Another embodiment utilizes an appliance's on-off switch to operate the ejector.
Abstract:
An electrical geophysical connector comprising an outer housing, a first connection member and a second connection member. First and second coacting electrical contacts are positioned in the first and second members, respectively. The first member includes a rigid outer shell and a resilient inner core bonded to the first electrical contacts. The first ends of the first contacts are positioned in cavities located in one end of the inner core and resilient seal rings are formed about the cavities for engaging and sealing the coacting engagement of the first and second contacts. A dust cap is rotatably mounted with a 360.degree. rotation to the housing and the exterior of the housing is tri-lobed in cross section for ease of gripping.
