Patent number: 10249980Abstract: The present invention provides a system for providing a stress reduction apparatus for a ceramic electrical penetrator or pin in a subsea environment. More specifically, the present invention provides a deformable translatable seat in an annular pocket that prevents the transfer of shear forces from a shell or fixture to a ceramic electrical penetrator or pin. The present invention provides a relatively soft metal seat that conforms to the profile of the shoulder of a mating electrical penetrator or pin and deforms to reduce or eliminate concentrated bearing stresses. The deformable translatable seat may also shift and deform within the annular pocket to relieve shearing stresses exerted on the electrical penetrator or pin by the shell or fixture.Type: GrantFiled: December 19, 2016Date of Patent: April 2, 2019Assignee: Teledyne Instruments, Inc.Inventors: Alan D. McCleary, Christopher M. Eliassen

Patent number: 9117566Abstract: One or more insulated conductive wire assemblies are incorporated in a pressure balanced, oil-filled (PBOF) hose. Each conductive wire assembly has a pair of conductive wires each having an insulation layer, an insulating material surrounding the insulated wires, and an outer insulating layer surrounding the insulating material. The insulating material may be selected to have a dielectric constant substantially matching the dielectric constant of the oil in the PBOF hose, so that the insulated pair of conductors perform in the same way both before and after the assembly is submerged in oil in the jumper hose. One or more parameters of the conductive wire assembly are selected such that the assembly has a predetermined impedance when submerged in oil within the PBOF hose.Type: GrantFiled: March 14, 2013Date of Patent: August 25, 2015Assignee: Teledyne Instruments, Inc.Inventors: Alan D. McCleary, John Bradley Croom, Huijiang Xi, Michael C. Greene

Patent number: 8734026Abstract: A subsea connector unit with an integrated, bi-directional electrical to optical (EO) media converter is provided which has a first end configured for connection to standard subsea electrical cable connector unit and a second end joined to a subsea optical or electro-optical ethernet jumper cable. The EO media converter has one or more electrical input/output (I/O) junctions which communicate with electrical signal conductors in a connected electrical ethernet cable and one or more optical I/O junctions which are connected to one or more optical fibers extending from the subsea jumper cable. Electrical input signals received at the electrical I/O junctions are converted into corresponding optical signals provided at the optical I/O junctions for transmission along the subsea jumper cable, and optical input signals received from the jumper cable are converted to electrical signals at the electrical I/O junctions for output to the electrical cable.Type: GrantFiled: August 15, 2012Date of Patent: May 27, 2014Assignee: Teledyne Instruments, Inc.Inventors: Kenneth M. Nagengast, Alan D. McCleary, Huijiang Xi
