Patents by Inventor Bruce Erwin Proctor

Bruce Erwin Proctor 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).

  • Tension thrust ESPCP system
    Patent number: 6868912
    Abstract: A submersible pump assembly has a pump section, a seal section and a motor section. Within each section are shafts. The adjacent shaft sections are matingly engaged with one another, and are connected by fasteners. The fasteners consist of a key and a screw that fits within the key. The fasteners secure the adjacent shaft sections to one another to transmit torque from one shaft to the other, and to transmit thrust in axial tension from one shaft to the other.
    Type: Grant

  • Gas separating intake for progressing cavity pumps
    Patent number: 6705402
    Abstract: A downhole pump assembly is suspended by tubing in a well. The pump assembly has a separator attached below a progressing cavity pump with a flexible shaft to accommodate the concentric path of the shaft of the separator and the eccentric path of the rotor of the pump. Vanes on the shaft of the separator use centrifugal force to separate the heavier liquids from the lighter gases in the well fluids. The separator discharges the gas into the casing and the liquid to the pump. A motor drives both the separator and the pump. A gear reduction unit is located between the motor and the pump in order to reduce the rotational speed from the motor to the desired rotational speed of the rotor for the pump.
