Fire Resistant Corrugated Coaxial Cable
US Patent 11942233
Published March 26, 2024
Inventor: William E. Rogers, Danville, CA, USA
Assignee: American Fire Wire, Inc., Minden, NV, USA
A fire resistant corrugated coaxial cable is described that employs a hightemperature, insulating alkaline earth silicate (AES) wool dielectric. The AES
wool dielectric is devoid of water as a constituent. The AES wool may be
survivable under conditions of high heat, such as temperatures specified by
common fire test standards (e.g., 1850°F/1010°C for two hours). The cable is
configured to maintain a relatively coaxial relation between a center
conductor and an outer conductor even under aforementioned fire tests. A
layer of ceramifiable silicone rubber or refractory fiber wrap can surround
the outer conductor and continues to insulate it from the outside if a lowsmoke zero-halogen (LSZH) jacket burns away.

Electric Cable
US Patent 11942241
Published March 26, 2024
Inventor and Assignee: Lubomir Dostal, Winchester, MA, USA
An improved electric cable is disclosed herein. The resistance of the electric
cable of the present disclosure is surprisingly decreased despite a reduction
in the cross-sectional area of the conductor when at least one metal slug is
positioned at an end of the cable. Conductor wires, which may or may not
be individually insulated, may extend around a metal slug or through an
aperture of the slug. In combination with at least one metal slug, the cross-sectional area of individual wires or the amount of wires within a stranded
wire cable may be substantially reduced without seeing an expected
proportionate increase in electrical resistance, and surprisingly, a decrease
in resistance may be observed.
