Patents by Inventor Geoffrey Kolbe

Geoffrey Kolbe 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).

  • Pressure monitor
    Patent number: 6386028
    Abstract: The present invention provides an peak chamber pressure measuring apparatus 1 for use with a regular firearm 2 using a given ammunition. The apparatus comprises: a piezoelectric accelerometer 3 for generating a recoil acceleration electrical output signal from recoil acceleration of the firearm upon discharge thereof, and provided with releasable mounting means 6 for rigidly securing the accelerometer 3 to the firearm 2 in proximity to its chamber 11. The accelerometer 3 has signal output means 12 coupled to a signal processing means 13. The signal processing means 13 converts said recoil acceleration electrical output signal which is representative of the peak chamber pressure, using a conversion relationship based on the mass of each of the firearm, and the projectile and the propellant components of the ammunition, and the firearm bore diameter, the signal processing means 13 having signal output means for connection to output signal display means 16.
