A chair for particular use in clinical or hospital environments has a frame to which a support material is secured. The support material may form a chair back and/or a seat for the chair to provide support to the chair occupant. The support material may be made from a textile of interwoven strands wherein some of the interwoven strands include copper containing particles, such as copper iodide or copper oxide within the textile fibers.

A liquid containment device is provided for a liquid filled transformer having a tank and a bushing attached to a surface of the tank, the bushing including a terminal having a terminal head including a terminal head opening and a porcelain bushing. A terminal head attachment is attached to the terminal head of the bushing. A housing is provided having an open end, a closed end and a contact pole opening formed on the closed end, the housing encapsulating the bushing and the terminal head attachment. A contact pole is attached to the terminal head attachment and extends through the contact pole opening of the housing. A contact is attached to the contact pole and a housing fastener is fastened on the contact pole to press the housing onto the surface of the tank.

A chair for particular use in clinical or hospital environments has a frame to which a support material is secured. The frame may include a seat frame and a separate head rest frame. The support material may be provided over the seat frame and the over the head rest frame. The support material may be made from a textile of interwoven strands wherein some of the interwoven strands include copper containing particles such as copper iodide or copper oxide within the textile fibers.

An arrangement and a method for the gradual shutoff of potential in high voltage technology. The arrangement has at least one armature body, an electrically insulating film, and electrically conductive regions. The electrically conductive regions are arranged between layers of the electrically insulating films, and at least parts of the electrically insulating film are arranged around the at least one armature body. The arrangement is used in direct current applications. Resistive compensation currents are reduced and/or avoided along the electrically insulating film, and/or by an armature body, which functions as a first gradual potential shutoff coating, and/or by way of the electrical contacting of the outermost electrically conductive region between layers of electrically insulating film via an electrical contact through an opening in the outer layer of the insulating film.

Method and apparatus for improving sound quality in audio cables, including a plurality of equally spaced conductive discs separated by a gap and configured in a generally linear array, each of the discs having an annular shape with planar sides, an outer diameter, a center hole having a diameter, and a thickness. The disc array is placed around an audio signal cable such that the planar sides of the discs are oriented parallel to one another and perpendicular to signal cable axis. The spacing between discs is approximately four to ten times the thickness of said discs, and the disc diameter is between 2 and 4 times the diameter of the center hole.

An oil-oil bushing is disclosed which can include a rotationally symmetrical, paraboloid-like, hollow bushing element of a solid insulating material, along the axial extent of which there is formed radially toward the inside a tubular bushing channel, the wall thickness of which is tapered conically toward at least one of its two ends. An electrical bushing conductor can be fitted into the bushing channel with a form fit and protrude from it on both sides. At at least one of the two axial ends of the bushing channel there is arranged a hollow-cylindrical shielding element of a conductive material, which is thick-walled at least in certain regions, which element can enclose on one side a respective end of the bushing channel, and on another side, electrically contact a connecting conductor.

High capacity (10 GW, for example) passively cooled non-superconducting underground high voltage direct current electric power transmission lines (100) of very low loss (1% per 1,000 km, for example) and competitive cost. The transmission lines (100) include segment modules (101) linked together with compliant splice modules (102) between the segments (101), typically installed in a protective conduit (103). The segment modules (101) include relatively rigid pipe-shaped conductors (117) insulated by pipe-like solid insulating layers (131) to form segment modules (101) that resemble pipe. The segment modules (101) are linked together through radially and axially compliant splice modules (102) to form the transmission line (100). There are preferably wheels (300) deployed to ease insertion and removal of the assembled segment modules (101) and splice modules (102) into the conduit (103), to center each segment module (101) within the conduit (103), and/or to provide motive force and/or braking to allow the assembled segment modules (101) and splice modules (102) to be installed on a slope.
