  • DYNAMICALLY BALANCED IN-LINE WHEEL VEHICLE
    Publication number: 20240326944
    Abstract: A family of vehicles is presented which exploit dynamic controls to stabilize in-line two wheeled vehicles. The stabilization results in improved safety at high speeds and on uncooperative surfaces. Stabilization affords balance at zero speed without auxiliary support means. Transformational wheel base length affords high visibility at low speeds and low drag at high speeds. In wheel chair configurations transforming wheel base length allows navigation up and down stairs.

  • DIRT PICK-UP RESISTANT COMPOSITION
    Publication number: 20240279502
    Abstract: Water-based compositions that are resistant to dirt pickup, efflorescence, tannin bleed-through and surfactant leaching are described. The water-based composition includes a latex or water-dispersible polymer and a non-VOC UV-VIS (preferably, ultraviolet) absorber as a dirt pickup resistance additive. Methods of making water-based compositions including a non-VOC UV-VIS absorber as an additive are also described.

  • Frac plug slips with uniform breaking mechanism and method
    Patent number: 11959355
    Abstract: A downhole tool for sealing a well includes a push ring, a first slip ring located adjacent to the push ring, a first wedge located adjacent to the first slip ring and configured to radially push the first slip ring and separate the first slip ring into individual parts, and a sealing element located adjacent to the first wedge and configured to seal the well. An upstream end of the first slip ring and a downstream end of the push ring form a wavy interface when in contact. The wavy interface locks the first slip ring relative to the push ring to prevent a rotation of the first slip ring relative to the push ring.
