Latest Patents

One of Womack's latest patents is for a superconducting electrical conductor. This innovative conductor comprises a porous substrate of bonded fibers coated with ceramic oxide superconducting material of the perovskite type. The design ensures that its critical temperature of superconductivity is at or above the boiling point of liquid nitrogen. To form an electrical cable, the conductor is encased within an inner tube, which is then surrounded by an outer tube that defines an evacuated annular space. This configuration provides a thermal barrier between the substrate, which is bathed in liquid nitrogen, and the ambient environment. Additionally, electrical and heat insulation surrounds the outer tube. Joint connectors, made of multiple rigid rods coated with superconducting material and held in a perforated frame, are utilized to connect the facing ends of the substrate, facilitating an electrical connection from one length of conductor to the next.

Another significant patent by Womack is a flowmeter for a moving packed bed. This apparatus and method measure the flow of a packed bed of particles moving in a primary stream. It involves positioning a feedpipe with an open end facing downstream in the primary stream and feeding a secondary stream of particles through the feedpipe. This setup satisfies a void that would otherwise form downstream due to the passage of the primary stream. The flow of the primary stream is proportional to the flow of the secondary stream, which can be measured by either the amount of particles metered into the feedpipe or by connecting a hopper to the feedpipe and measuring the rate at which the level of particles in the hopper falls.
