  • Sealed drive for connecting progressive cavity pump rotors to universal joints
    Patent number: 11371502
    Abstract: A progressive cavity pump includes a sealed drive between the rotor and universal joint. The universal joint includes a socket configured to receive a drive shaft of the rotor. A cover, such as a locking nut, is disposed over the connection between the rotor and universal joint. Seals are retained in place by the locking nut to prevent abrasive materials from entering into the interface between the rotor and the universal joint.

  • PROGRESSIVE CAVITY PUMP UNIVERSAL JOINT
    Publication number: 20210348608
    Abstract: A progressive cavity pump includes a torque input disposed on a rotational axis, a resilient stator cylinder, a screw rotor situated within the resilient stator cylinder, and a universal joint. The universal joint rotationally couples the screw rotor to the torque input, and includes a swivel block, a linkage, a universal joint coupler, and a fastener. The swivel block has opposite laterally extending trunnions. The linkage extends parallel to the rotational axis, and laterally captures the laterally extending trunnions. The universal joint coupler is disposed around the swivel block and adjacent the linkage. The fastener connects the universal joint to the swivel block. The fastener and the laterally extending trunnions cooperate to transmit torque about the rotational axis through the linkage, while permitting lateral translation of the universal joint coupler in a plane orthogonal to the rotational axis.

  • Molded acoustic and decorative mats and methods for forming the same
    Patent number: 6382350
    Abstract: A multi-layer acoustically absorptive mat includes a base layer having an exposure hole defined therein. A face layer is disposed adjacent the base layer. An acoustic absorbing layer is interposed between the base layer and the face layer. The acoustic absorbing layer includes an exposed portion extending across the exposure hole wherein the base layer is bonded to the acoustic absorbing layer.
