20080217042 | METHOD FOR MAKING RAIL BONDS - A rail bond for bonding a wire or cable to a surface of rail includes a copper sheet and weld metal material solidified from molten metal material. A copper or other metal sheet is placed against the surface of the rail where the bond is to be located, and against an opening of a chamber of a graphite mold where the molten weld metal material is formed. Molten material is produced into liquid form and flows to the copper sheet material. This causes the copper sheet material to melt and bond against the steel rail. The presence of the copper sheet material between the molten weld metal and the rail surface reduces the amount of heating in the steel rail, and reduces the size of the heat affected zone (HAZ) in the steel rail. | 09-11-2008 |

20120255757 | SHIELDING DEVICE FOR PREVENTING WATER FLOWING INTO ELECTRONIC DEVICE - A shielding device includes an enclosure sidewall. The enclosure includes two side plates, a top plate and a connecting plate connected to the top plate. The connecting plate defines a through hole to engage the cable. The top plate is slanted relative to the sidewall. | 10-11-2012 |
20130075124 | High Voltage Direct Current Cable Termination Apparatus - A direct current cable termination apparatus for terminating a high voltage direct current cable, the apparatus includes a current-carrying device comprising a terminal portion of the direct current cable, the cable includes an electrical conductor, a circumferential electrically insulating layer located outside of the electrical conductor, and a circumferential conductive shield located outside of the insulating layer and the electrical conductor. The apparatus includes a housing having an outer shell, and the current-carrying device is adapted to extend in the axial direction of the outer shell. Along at least a part of the axial extension of the current-carrying device the outer shell extends axially with a space between its inner periphery and the current-carrying device. | 03-28-2013 |
20140041890 | RF COAXIAL TRANSMISSION LINE FOR A WELLBORE INCLUDING DUAL-WALL OUTER CONDUCTOR AND RELATED METHODS - A radio frequency (RF) coaxial transmission line to be positioned within a wellbore in a subterranean formation may include a series of coaxial sections coupled together in end-to-end relation. Each coaxial section may include an inner conductor, a dual-wall outer conductor surrounding the inner conductor, and a dielectric therebetween. Each of the dual-wall outer conductors may include an outer wall and an inner wall spaced apart therefrom defining a fluid passageway. Each coaxial section may further include a threaded endpiece coupled to each opposing end of the dual-wall outer conductor and having threads to define an overlapping mechanical threaded joint and an electrical joint with an adjacent threaded endpiece. | 02-13-2014 |
20140367135 | PRESSURIZED ELECTROMECHANICAL CABLE - An inventive pressurized cable is provided that simultaneously provides electrical connections and a supply of air, gas, or vacuum to an electromechanical device utilizing an existing connection on the device. The use of an existing cable connection for the supply of air or gas to provide positive pressure or a vacuum condition to an electromechanical enclosure allows for the use of standard electromechanical components without alteration and potential voiding of existing warranties. The present invention finds particular utility in the field of industrial automation where motors are subjected to coolant liquids and other types of contaminants that tend to infiltrate the motor seals, especially when the motor is shut down which causes a negative pressure inside the motor case that draws moisture in. Reactive gasses may be introduced with the inventive positive pressure cable that act to neutralize or condition harmful pollutants generated by the motor such as ozone. | 12-18-2014 |
20150325997 | Downhole Cable Termination Systems - Downhole cable termination apparatus for terminating a cable which is to extend into a downhole environment from a tubing hanger to electrical equipment, the apparatus comprising: an electrical contact for electrical engagement with a conductor of the cable to form a termination, which, in use, is to be electrically insulated by an insulating portion; and a housing defining a chamber for receiving the insulating portion and in which the internal pressure is isolated from pressure in the downhole environment. | 11-12-2015 |
20160027552 | WATER-STOP STRUCTURE FOR ELECTRICAL WIRE, AND METHOD FOR MANUFACTURING SAME - A water-stop structure for electrical wire includes: a terminal including an electrical wire connection portion; and an electrical wire in which an outer circumference of a conductor including a plurality of single wires is coated with an insulation coating portion and which is swaged to be fixed to the electrical wire connection portion, a water-stop agent being filled into a gap in the insulation coating portion to thereby perform water stop in the electrical wire. The water-stop agent includes a fluorescent agent. | 01-28-2016 |

20130081844 | High Voltage Direct Current Cable Termination Apparatus - A direct current cable termination apparatus for terminating a high voltage direct current cable, the apparatus includes a current-carrying device including a terminal portion of the direct current cable, the cable at least including an electrical conductor, a electrically insulating layer located outside of the electrical conductor, and a conductive shield located outside of the insulating layer and the electrical conductor. The apparatus includes a housing including a tubular outer shell with an inner periphery, the outer shell defining a longitudinal axis and being formed by an electrically insulating and polymer-containing material. The current-carrying device extends in the axial direction of the outer shell. Along at least a part of the axial extension of the current-carrying device the outer shell extends axially with a space between its inner periphery and the current-carrying device. The housing is adapted to separate the space from an atmosphere outside the outer shell. | 04-04-2013 |
20140096992 | PRESSURE BALANCED CONNECTOR TERMINATION - A pressure-balanced sleeve assembly for an electrical cable termination is disclosed. The sleeve assembly includes an outer sleeve surrounding the electrical cable; a chamber defined between the outer sleeve and the electrical cable; dielectric fluid contained within the chamber; and a seal that is positioned between the outer sleeve and the electrical cable to delimit and seal an end of the chamber to prevent the escapement of the dielectric fluid from the chamber, the seal being moveable along the cable in response to differences between a pressure within the chamber and a pressure outside of the chamber. Also disclosed herein is a pressure-balanced electrical cable assembly and a method of pressure-balancing a termination of an electrical cable. | 04-10-2014 |
