  • Patent number: 11148072
    Abstract: Methods of separating a multiphase mixture are provided. The multiphase flow can include petrochemicals. The multiphase flow is flowed through a vane assembly having a plurality of curved passages. The multiphase mixture is gradually decelerated such that it collides with surfaces of the vane assembly at relatively oblique angles and at lower relative speeds. Such a configuration can reduce droplet breakup which, in turn, can preserve larger droplet sizes that are more likely to settle to a liquid bed below the inlet diverter due to gravity.
    Type: Grant

    Date of Patent: October 19, 2021
    Assignee: WESTERMAN, INC.

  • Patent number: 10016002
    Abstract: Garments having an evacuation harness that are intended for connection to each other, with each garment having an outer wear unit including at least a torso portion and an evacuation harness that includes a torso strap system connected to the outer wear unit. The garments may include an outer wear pant having a leg strap system. Garments that are similar to each other conveniently may be used in a rescue garment system. Also disclosed are methods of connecting an individual to be rescued to one or more rescuers wearing similar garments.

  • Patent number: 10010729
    Abstract: A harness having a deployable rappelling assembly is disclosed. The harness includes a strap construction including an upper torso securing portion having shoulder straps that extend from a rear torso portion to a front torso portion, a leg securing portion extending downward from the rear torso portion and having right and left leg straps, each of the left and right leg straps including a releasable connector, and a rappelling assembly connected to the front torso portion. The rappelling assembly may fold from a stowed position to a deployed position, and include loops and a cross member. The leg straps may be passed through the loops to connect the front torso portion to the leg securing portion for climbing or rappelling. The harness also may be incorporated into a garment.

  • Patent number: 9724624
    Abstract: An inlet diverter is provided for separating multiphase mixtures. The inlet diverter has curved vanes which define flow passages between adjacent vanes. The passages are arranged such that the inlet diverter discharges flow from the passages toward the inlet.

  • Patent number: 9498008
    Abstract: Garments having an evacuation harness that are intended for connection to each other, with each garment having an outer wear unit including at least a torso portion and an evacuation harness that includes a torso strap system connected to the outer wear unit, a drag strap coupling connected to the torso strap system and extending rearward relative to the outer wear unit, and a drag strap connected at a first end to the torso strap system at a position above the drag strap coupling and the drag strap being selectively extendible rearward relative to the outer wear unit. Also disclosed are methods of connecting a rescuer wearing a garment having an evacuation harness to an individual wearing a similarly configured garment having an evacuation harness.
