Set of charts detailing the effects of filter, porosity, puff frequency, and blends on smoke delivery.

Analysis of results for Present Brand vs Ideal Brand Study for use in development of ultra-low-tar cigarette (0-5 mg). In summary, "0-5 mg smokers appear to be getting even less from their present brands than the deliveries of those brands would justify" especially with regard to tobacco taste and aroma, refreshment, satisfaction, and ease of draw.

Study designed to answer the question: "To what extent is daily smoke intake a function of the cigarette smoked?" and to determine whether such changes occur within smoking of a single cigarette, or as a function of the number of cigarettes smoked. Study design includes smokers switched from higher and lower delivery cigarettes, with values recorded for mean daily smoke intake, number of cigarettes smoked, and mean smoke intake/cigarette/day. Concludes that further research is contingent on findings, with the goal to establish how puffing profiles are altered to affect the reduction or increase in intake.

Purchase request for SEX-2 study which identifies three brands for testing: Control Marlboro (20 mg Tar), Low delivery Marlboro (14-15 mg), and High Delivery Marlboro (25-26 mg).

Describes test developed to measure consumer perception of puff count changes. Recommends testing cigarettes varying in puff count from 9 to 6.5 puffs, while maintaining similar blend, resistance to draw, dilution levels, and tar per puff.

Lays out the goals and objectives of a research study on human smoking habits. Summarizes past findings that nicotine yield "depends more on the smoker himself than on the cigarette he smokes" and speculates that within a given brand the need for nicotine "is quite different between individuals...leading to a wide spectrum of the actual parameters." Claims that smoking provides a "short-term regulated system" for nicotine delivery "settled by the smoker at each puff, more or less independently of the available quantity." Determines a need to pursue the question of whether specific products are suited to specific smokers, through investigation of smoking behavior of "a few well selected smokers". Concludes with a list of objectives to achieve the stated goal.

Charts of puff by puff smoke delivery and pressure drop for cigarette prototypes with differing ventilation levels (20-40%).

Public statement by B&W addressing Barclay controversy and use of Actron filter. Claims that the Actron filter improves taste delivery through unique smoke swirl impacting a large number of taste sensors in the mouth simultaneously. Discusses deficiencies of FTC machine testing system, and argues against singling out Barclay cigarettes for exclusion from this test methodology given the many modes of compensation possible among brands for human smokers.

Study analyzing product design components which may be used to increase cigarette puff count. Describes the effects of burn retardants on puff counts for various B&W tobacco blends. Finds B&W products yield half to a full puff less than their major KS competitors, and from half to two puffs less in 100's. Suggests differences may be due in part to lack of ventilation of B&W products, and implementation is recommended. Suggests other differences including paper permeability, tobacco density, low phosphate paper, and differences in blends. Notes use of DAP in Marlboro acts as a burn retardant. Recommends further work toward application of burn retardants.

Brief summary of projects to determine influence of cigarette and filter design features on cigarette perfromance. Features tested include circumference, density, blend, shred cut width, expanded tobacco, and paper, CA-web, and charcoal-on-tow filters. Preformance measures include static burn time, puff count, TPM deliviery, pressure drop/flow rate, puff volume, and filter efficiency.
