Thelma C. Heatwole September 11, 1967 Recently Ron Tamol has been developing a technique Further Ideas for Controlling Cigarette Delivery for obtaining a flat puffed profile for a cigarette~ to coat holes in the last half of the"cigarette paper. e in the latter half of the cig,arette. -His technique is Basically he has developed a scheme.for air dilution These holes.open as the coal progresses down the solution a burn accelerator such as potassium.nitrate, cigarette.~ My idea is incorpoiiate into the coating etc. This would insure more rapid b urning in the coated area and perhaps overcome the slower burning time resulting from:the air dilution. Extending this thought further, it would appear r cigarette with slow static burning rate at the beginning and rapid static burning rate at the end. Thus a high puff count cigarette could be obtained with low delivery. that we could use a very slow burning paper to make the cigarette and print or coat onto the last halfef the cigarette a burn accelerator, thus making a specifically located burn accelerator on the cigarette ; Further extension of the idea of using a paper might also result in a way of obtaining air dilution in the latter half of the cigarette. By half of the cigarette paper, we possibly could obtain dilution by having the paper burn back ahead of the _ printing small spots or small lines in the latter coal for specific narrow lines, these lines being randomly printed on the paper from a solution perhaps potassium or calcium nitrate with some bodying agent in it (perhaps sugar). In sumnary, it appears the techniques developed by Ron Tamol for printing can be extended to incorpcr ate the printing of burn accelerators to whatever advantage we might want. While I believe this method might be hard to control, I believe it is a way of controlling the delivery of the cigarette and should be patented to protect our position in this area. HSM:gmm cc: •'br.
