  • Patent number: 12036527
    Abstract: A system is disclosed for producing ultra-high-molecular-weight (UHMW) poly-alpha-olefins (PAO) for use as pipeline drag reducing agents, having improved thermal efficiency and reduced branching of the PAO. The system comprises hinged pairs of shells, each pair of shells comprising a grid of larger hemispherical voids connected by smaller hemicylindrical passages, arranged in a serpentine pattern along the surface area of the shell. When the hinged pairs of shells are shut, they form a pattern of spherical voids which can be connected to an inlet port, which receives a combination of alpha-olefin monomer feedstock and a titanium trichloride catalyst. A reactor chamber houses a plurality of these hinged pairs of shells, which may slide into slots inside the reactor chamber spaced such that each adjacent hinged pair of shells abuts the outer surface of the next when shut and inserted. The reactor chamber is cooled by an inert gas.

  • Patent number: 12023643
    Abstract: The present invention relates, in general, to a system and method for focusing gas distribution through a series of three-dimensionally (3D) printed lattice heating elements within an electric catalyst unit in order to promote ammonia dissociation. The present invention allows gaseous ammonia to be continuously heated as it flows in series through ceramic tubes containing 3D printed lattice heating elements. The lattice structure of the heating elements provides a balance between surface area and heat dissipation, allowing the heating elements to reach a suitable temperature to perform ammonia dissociation, but which are not oversaturated with heat which could result in failure or melting of the heating elements.

  • Patent number: 12017513
    Abstract: The present invention is a hand sanitizer, air purification, fogger vehicle mount, or combination thereof, attach to a dashboard of a vehicle. Its purpose is to maximize disinfecting opportunities as a countermeasure to the spread of disease, including COVID-19. As a hand sanitizer, this invention is a hand-free device that minimizes cross-contamination among vehicle patrons during operation. A sensor, activated by hand proximity, sends a signal to a controller, then to a pump to dispense a portion-controlled volume of hand sanitizer. To disinfect airborne antigens, HEPA filtration and UV light are utilized. Pathogen lingering on surfaces are disinfected by a fogger, which dispenses atomized droplets throughout a vehicle. To eliminate exposure to nebulized sanitizer, the controller may receive a wireless signal from outside the vehicle. Independently powered, a vehicle can be sanitized each time it arrives at a destination, made ready to transport the next group of patrons safely.

  • Patent number: 11980697
    Abstract: A latch and lock assembly includes a lever pivotable between a latched and unlatched position. A first actuator selectively moves a locking tab between a locked and unlocked position. In the locked position, the locking tab blocks pivotable movement of the lever from the latched position to the unlatched position. In the unlocked position, the locking tab allows pivotable movement of the lever from the latched position to the unlatched position. A second actuator selectively rotates a door opening tab between a first and second position when the locking tab is in the unlocked position is included. When the door opening tab is in the first position the lever is in a latched position, and when the door opening tab is rotated from the first position to the second position, the door opening tab abuts the lever and urges the lever from the latched position to the unlatched position.
