Patents by Inventor Arthur K. Wickson

Arthur K. Wickson has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 4266148
    Abstract: A thyristor switch system completes a circuit with a much higher rate of current rise than a thyristor alone is capable of delivering. The invention limits the current through the load during the "priming" period of the thyristor that precedes the application of a high current pulse through the load.
    Type: Grant

  • Patent number: 4081853
    Abstract: A plurality of fuses are connected in a general parallel configuration for protecting a circuit, the fuses being serially connected with inductances of varying magnitude such that steady state current may be divided equally among the fuses permitting the use of fuses of lower rating. During an overcurrent surge, substantially the entire current overload is applied to each fuse in turn so that the total elapsed time for opening the circuit is less than with fuses alone.

  • Patent number: 3968381
    Abstract: An arc type switch has means to inject an auxiliary plasma between the main switch electrodes with high initial velocity. The switch conduction is initiated through a plasma that is already in motion along the surfaces of the main electrodes thereby reducing localized deterioration of the faces and distributing the localized heating to facilitate cooling of the electrodes. The configuration of the main electrodes is such as to continue forcing the main plasma by electromagnetic action in the same direction as the injected plasma.
