  • Self-sealing flow frame for flow battery stack
    Patent number: 9728791
    Abstract: A self-sealing flow frame is provided having a first frame component and a second frame component. Each frame component is provided with a tongue-and-groove configuration that when assembled forms a tessellation engagement, which creates the seal. When each frame component is assembled into a flow frame, with the inner surfaces facing towards each other, the tongue-and-groove arrangements create a seal profile that circumscribe constituent parts of a device within which the self-sealing flow frame is being employed. As the frame components are compressively secured and fastened together, a tessellation engagement of the seal profile forms the fluid seal. Fluids of the device are prevented from exfiltrating the device, and are contained within the self-sealing flow frame by the fluid seal.

  • Tunnel liner building method and building panels therefor
    Patent number: 5980156
    Abstract: Tunnel liners are formed from panels of arched sheet material. The panels include a central portion, inclined side portions and wing portions. One of the wing portions has a hook portion and the other of the wing portions has a receptacle portion. The hook portions and receptacle portions are constructed so as to snap-fit with respective receptacle portions and hook portions of adjacent panels. Panels can thus be more easily be assembled together. Panels can also be continuously seamed together from the underside, i.e., from within an arched assembly of panels.
