Latest Patents
John R. Shepheard holds a patent for an electric circuit interrupting device. This invention features a thyratron that can be utilized as a circuit interrupting protective device. The design includes an apertured grid situated between the anode and cathode, which is divided transversely into two parts separated by an insulating layer. Both surfaces of the composite grid, which are remote from the insulating layer, carry conductive meshes that cover the exits of the apertures in the grid. The dimensions of the insulating layer and the meshes are carefully designed to ensure that no point within an aperture is further from a part of the grid or a mesh than the Debye distance. This design reduces the effects of Debye shielding when a negative potential is applied, allowing for effective quenching of discharges.
