Woodrow Gondron 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).
Abstract: A pulser providing pressure based accoustic telemetry in a fluid column includes a formed turbine and valve wheel moveable as one unit, an aft turbine configured to drive the valve wheel and a brake to inhibit movement of the aft turbine. During periods when the aft turbine is slowed relative to the formed turbine and valve wheel, the aft turbine blocks misalign with blades of the valve wheel inhibiting fluid flow therepast. A pressure buildup is caused hereby until the brake is released allowing the aft turbine blades to realign with the valve wheel by resuming speed rotation thereby terminating pressure buildup.
