  • Publication number: 20240125196
    Abstract: A wellhead assembly includes a containment system having a mechanical barrier, a tertiary wiper, and a fluid jet assembly. A mechanical barrier includes a body disposed in a housing, the body having an opening extending through an axial thickness of the body. A tertiary wiper has an elastomeric body with a hole extending centrally therethrough. A fluid jet assembly includes a jet assembly body having a wall defining a cavity extending axially through the jet assembly body and an array of nozzles positioned circumferentially around the wall, wherein each nozzle has an outlet directed in a radially inward direction from the wall toward a central region in the cavity. The components of the containment system are arranged an axially stacked arrangement relative to each other.

  • Publication number: 20210148441
    Abstract: A machine for the conversion of segmented linear force into rational force around a fulcrum at a mechanical advantage to an included or attached drive mechanism. A body consisting of pivot arms, drive mechanism, primary shaft, and bearings. With the pivot arms bolted around standard bearings that are attached to a primary stationary primary shaft a mechanical advantage of a pulley is created to an included or attached drive mechanism. The segmented linear force in this application includes, but is not limited to, an electromagnetic force or compressed air or manual labor. A machine that converts segmented linear force at a mechanical advantage directly to an incorporated or attached drive mechanism such as a gear, pulley, or drive secondary shaft.

  • Patent number: 9680361
    Abstract: An electric motor apparatus that includes a disk with an increased mechanical advantage to the attached axle, with donut-shaped permanent magnets, windings, a fulcrum (A.K.A. axle), bearings, a commutator, and a single bearing conductor that replaces the brushes. The center axis consists of the windings and spools with the axis of the windings placed coradial in orbit around the fulcrum of a disk. The donut-shaped permanent magnets are cut with a slot to allow passage of the disk, spools, and windings. When windings of magnet wire are inserted with windings around the spools such that the center points of the faces of the spools are concentric to the same radius of the disk and pass through the center of a donut-shaped permanent magnet, and the windings are electrified with the correct polarity, the windings are repulsed magnetically in the direction of rotation of the orbit around the fulcrum (A.K.A. axle) causing the disk and axle to rotate.

  • Patent number: 9629970
    Abstract: A bi-level pressure support system and method of treating disordered breathing that optimizes the pressure delivered to the patient during inspiration and expiration to treat the disordered breathing while minimizing the delivered pressure for patient comfort. The pressure generating system generates a flow of breathing gas at an inspiratory positive airway pressure (IPAP) during inspiration and at an expiratory positive airway pressure (EPAP) during expirations. A controller monitor at least one of the following conditions: (1) snoring, (2) apneas, (3) hypopneas, or (4) a big leak in the pressure support system and adjusts the IPAP and the EPAP based on the occurrence of any one of these conditions.

The windings with the axis placed parallel to the orbit around the fulcrum on a disk. The donut-shaped permanent magnets are cut with a slot to allow passage of the disk, spools, and windings. When windings of magnet wire are inserted with the axis parallel to the orbit around an axle inside the center of a donut-shaped permanent magnet, and the windings are electrified with the correct polarity, the windings are repulsed magnetically in the direction of rotation of the orbit around the fulcrum causing the disk and axle to rotate.

  • Patent number: 8789527
    Abstract: A pressure support system that delivers a flow of gas to a patient's airway via a pressure generating system and a patient circuit. A controller receives a treatment set point from an input source and determines an adjusted treatment set point based on the treatment set point and a comfort feature function, which in one embodiment, is not based on a physiological condition of such a patient. In another embodiment, the controller provides a respiratory treatment therapy during a therapy session based on the treatment set point and the comfort feature, which is modified automatically during a therapy session without user intervention based on a comparison of the treatment set point to a treatment set point variable. The controller controls the operation of the pressure generating system based on the adjusted treatment set point or the combination of the treatment set point and the comfort feature.

  • Patent number: 8025052
    Abstract: A system and method of monitoring a patient, that in one embodiment, comprises determining a flow of gas generated by respiration of the patient, identifying a respiratory event entry and a respiratory event exit based on the flow of gas generated by respiration of the patient, and identifying a respiratory event when the identification of the respiratory event entry is followed by the identification of respiratory event exit.

  • Patent number: 7827988
    Abstract: A pressure support system and method of treating disordered breathing that optimizes the pressure delivered to the patient to treat the disordered breathing while minimizing the delivered pressure for patient comfort. The controller in the pressure support system operates as a set of prioritized control layers, wherein each control layer competes for control of the pressure generating system to implement a unique pressure control process. The pressure support system also controls the pressure provided to the patient based on the variability of the monitored data and a trend analysis of this data, including an indication of the skewness of the patient's inspiratory waveform.
