 process for extraction of soluble material from tobacco and 

 its transfer to another material. The receiving material 

 can be a different grade of tobacco or some other filler 

 material. Nicotine transfer is specifically discussed as 

 part of the process. The patent indicates that both the 

 donor tobacco and the receiving material can be employed in 

 smoking products.

The patent illustrates an extraction process for tobacco. 

 It refers to the previous literature on the subject and 

 discusses the uses of tobacco extracts as additives in 

 multiple stages of the manufacturing process, including use 

 as casing or as top dressing for "tobacco strip, " "cut 

 filler," or "other smokable materials." The extracts are 

 also potentially useful as filter additives. Specifically 

 mentioned filter substrates are polypropylene, polyester, 

 and low density polyethylene. The extracts can also be 

 placed inside cigarette pack wrappers to create "a desirable 

 cigarette aroma and 'pack aroma.'" 



Some of the extraction procedures described are specifically 

 designed to increase or decrease the extraction of nicotine. 

 That is, the solvent used in the process determines in large 

 measure the nicotine content of the final extract.
