Patents by Inventor H. Neal Nunnally

H. Neal Nunnally has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6803545
    Abstract: An electrically heating smoking system wherein tobacco smoke is generated by heating a portion of a cigarette with an electrical resistance heating element powered by lithium ion battery cells. The lithium ion battery cells supply current to the electrical resistance heating element with current up to 20 times greater than the recommended discharge rate. To prevent damage to the lithium ion battery cells under such high discharge conditions, the smoking system includes a controller which provides modulated pulses of electrical power from the battery cells to the resistance heating element during smoking of the cigarette.
    Type: Grant

  • Patent number: 5967148
    Abstract: A cigarette identifier system comprising an infrared emitter and an infrared detector located across an opening of a cigarette receiver, wherein the sensor registers changes in the transmission of the infrared beam across the opening so as to detect the differences in transmissivity of dense and less dense and portions of an inserted cigarette.

  • Patent number: 5954979
    Abstract: A novel electrical smoking system and method of establishing resistance to draw upon a cigarette while smoking a cigarette in an electrical smoking system comprising the step of operatively interposing a frit between a source of ambient air and the cigarette.

  • Patent number: 5902501
    Abstract: The present invention provides a cigarette identifier system comprising a coil at a location along the cigarette-receiving receptacle of the lighter, an oscillation circuit in communication with the coil and a controller configured to activate or deactivate the lighter responsively to output of the oscillator circuit.

  • Patent number: 5878752
    Abstract: Methods and apparatuses for cleaning an electrical lighter are provided. A sleeve, e.g., ceramic or metal, surrounds the heater fixture, and a resistive heating element is in thermal proximity with the sleeve. The resistive heating element is either a dedicated element or the cigarette heating elements. The sleeve serves as a aerosol barrier and condensate accumulator to protect other components. Periodically, e.g., substantially contemporaneously with a battery recharge, the heating element is activated to thermally liberate condensates deposited on the sleeve during smoking and also heats, and thereby cleans, other components. Also, a cleaning element is optionally inserted into the cigarette receptacle of the electrical lighter or placed at the exit thereof to absorb, attract and/or catalytically break down the thermally liberated condensates. The sleeve also directs a desired flow path for drawn air within an electrical lighter toward the cigarette.

  • Patent number: 4595027
    Abstract: A control system for a cigarette making machine to provide improved cigarette rod weight control by continual adjustment of a servo-positioned ecreteur knife at the tobacco supply vacuum belt of the cigarette maker. The servo is positioned by a dual mode control system wherein one mode is based on long term feedback of cigarette rod density, measured by a .beta. ray gauge and a second mode based on a high speed adaptive feed-forward control based on tobacco density on the supply vacuum belt measured by a pneumatic gauge.
