Patents by Inventor John C. Weigand

John C. Weigand 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: 9052163
    Abstract: An adjustable scope mount for a projectile weapon can include a base and a mounting piece pivotally attached to the base. The mounting piece can include a first bore that is substantially the same size as a first bore of the base and a second bore that is substantially the same size as a second bore of the base. The respective first bores of the base and mounting piece can be positioned such that when they completely overlap, the mounting piece is positioned at a first minute of angle setting. Likewise, the respective second bores of the base and mounting piece can be positioned such that when they completely overlap, the mounting piece is positioned at a second minute of angle setting. Related methods of using and manufacturing the adjustable scope mount are also described.

  • Patent number: 4600947
    Abstract: A television receiver includes an integrated circuit audio amplifier for having an inverting terminal, a noninverting terminal and an output terminal connected through a feedback resistor back to the inverting terminal. A first capacitor is coupled to the noninverting terminal and a second capacitor is coupled to the inverting terminal. A voltage divider normally establishes the first capacitor at a given potential. A source of regulated potential less than the given potential is coupled through a pair of series connected diodes to the first capacitor and through a single diode to the second capacitor, thus establishing two separate charging paths for said capacitors with the initial time constant of the path coupled to the noninverting terminal being longer than the initial time constant of the path coupled to the inverting terminal.
