Abstract: A bushing primarily for use in high temperature applications. In preferred embodiments the bushing comprises a rounded body formed from a single piece of metal wherein the body has an “M” shaped cross-section with a first outer leg, second outer leg, first inner leg and second inner leg, and wherein the first outer leg and second outer leg are both concave arcs about a central axis and form an outer circumference of the rounded body and wherein the first inner leg and second inner leg each have an arc formed in the leg to create a rounded channel that extends a longitudinal length of the rounded body along the central axis; and wherein the first inner leg and second inner leg transition between each other in a third concave arc.

Abstract: A fire suppressant mixture comprising: an organic or supplemental organic fire suppressant compound; a halogen element, and an organic compound, wherein the organic fire suppressant compound, the halogen element and the organic compound are combined such that a boiling point of the mixture is lower than the boiling point of the organic fire suppressant. In some embodiments, the organic fire suppressant compound is FK 5-1-12 and the organic compound is carbon dioxide. In other embodiments, the mixture is supplemented with an additional organic compound such as CF3I or 2,2-Dichloro-1,1,1-trifluoroethane (R123), or an halogen element. In some embodiments an inorganic pressurizing gas, such as nitrogen, is also added.

Abstract: A coaxial cable structure incorporating a physical interruption in the outer jacket or sheath of the cable. This interrupts the continuity of the outer conductor and serves to block DC (direct current) and low frequency electrical signals. Also, it greatly reduces heat transmission along the cable. The interruption is achieved by placing a specially fabricated stub in series with the coaxial cable. The resulting coaxial cable assembly acts like a band-pass filter which, although blocking DC and lower frequency electrical signals, is able to transmit RF (radio frequency) signals at selected frequencies. The entire assembly, including the stub, can be made hermetic.
