  • Patent number: 10274197
    Abstract: A tape dispensing device for disposal around a cigarette lighter. The present invention includes a tubular support defining a central opening and on which a roll of tape is wound, such as a roll of duct tape. The device further includes a lighter having a body in which fuel is stored and an ignition source on an upper end thereof that is removably positionable within the central opening of the tubular support. The body of the lighter is secured to the periphery of the central opening of the tubular support via a press fit.

  • Patent number: 10222061
    Abstract: Methods, burner, apparatuses, and systems are provided for controlling a velocity of a jet of gas exiting a burner when the gas is heated or not and at a corresponding second higher temperature or lower first temperature. Through the use of a temperature-sensitive magnetic valve, the flow of a gas can be redirected to maintain velocity of the gas as delivered to a combustion chamber based on the temperature of the gas. The temperature-sensitive magnetic valve can redirect flow of the gas based on the magnetic state of a ferromagnetic material. The state of the temperature-sensitive magnetic valve changes based on the temperature of the gas to maintain the velocity of the gas delivered through an outlet of the burner to the combustion chamber. Thus, heated gases and standard temperature gases can be delivered at approximately equal velocities thus maintaining flame size and shape.
