Latest Patents

Fesler holds a patent for a Microwave Waveguide Seal Assembly. This invention presents a microwave waveguide that includes a gas-tight seal, providing pressure isolation between two portions of the waveguide. An important feature of this invention is the upper flange, which includes a threaded axial opening for receiving and retaining a threadably mated dielectric filling material. The design ensures that if the thread pitch is small relative to the signal wavelength, the threaded section maintains the same electrical characteristics as a smooth waveguide. This structure offers an economical and practical method for retaining a solid dielectric filling material in a waveguide against high pressure without altering the effective diameter of the waveguide. Additionally, the invention features a novel high-pressure seal between the upper and lower flanges surrounding the threaded axial opening, utilizing a membrane or disk of soft material, preferably polytetrafluoroethylene (PTFE). This design allows for high-pressure gas operation in hostile environmental conditions with reduced failure rates compared to prior art sealing arrangements.
