Text: Great Britain Patent No. 1,240,867 (“Stoyle”) (J.A. 1004–08) describes an apparatus for “heating [] oil or other mixtures of oil and [CO2], oil and water, or oil, [CO2] and water to produce smoke or mist . . . for testing ventilation systems or for theatrical effects.” Stoyle p. 1 ll. 11– 17. Figure 3 of Stoyle is depicted below. 6 REDLINE DETECTION, LLC v. STAR ENVIROTECH, INC. Id. fig.3. “The fluid inlet means 14 are connected to a generator capable of producing a foam of oil and [CO2] gas. The oil/gas mixture is forced into the space 7 and, passing through the gaps between the knurlings, eventually reaches the outlet means 10, where it emerges in the form of a mist or smoke.” Id. p. 2 ll. 101–08. This allows for “a relatively large contact area for heating the oil/gas mixture[,] . . . [making] the heating very uniform and easy to control.” Id. p. 2 ll. 109–11, 118–19. Additionally, this apparatus permits the “production of oil smokes and mists with a relatively lower proportion of gas in the mixture by comparison with other types of heater[s].” Id. p. 3 ll. 15–18.
