Mechanical Smoking Using a Pressure Procedure - A New Smoking Procedure and its Application Conditions / Druckverrauchen - Eine neue Abrauchmethode und Möglichkeiten ihrer Anwendung
Page range: 81 - 88
Abstract
The present paper describes a new method of mechanical smoking using a pressure procedure and condensing the smoke by means of a nozzle. The advantage of the described procedure consists in the possibility of direct application of native condensate in biological tests without uncontrolled aging effects. The apparatus permits to condense and analyse the sidestream smoke separately

Theory of Relative Smoke Yield / Zur Theorie der Rauchausbeute
Page range: 89 - 92
Abstract
In 1957 Keith and Newsome concluded from an experiment that the efficiency of the combustion process, i. e. the relative smoke yield, is independent of the distance between the incandescent zone and cigarette tip. It is shown in the present paper that the results set forth by Keith and Newsome are void of the theoretical accuracy which, in view of the relevance of such results, should perhaps form the basis of interpretation. From the alleged constancy of the relative smoke yield the author of this paper draws theoretical conclusions the verification of which will facilitate, in a reliable way, the decision upon the truth of the said allegation. An empiric examination of the author's conclusions is recommendable.

The Influence of Tobacco Moisture Content on the Composition of Mainstream Smoke Yield as well as on the Temperature in the Combustion Zone / Einfluss des Feuchtigkeitsgehaltes von Cigaretten auf die Zusammensetzung des Rauches und die Glutzonentemperatur
Page range: 93 - 100
Abstract
The authors studied the influence of tobacco moisture content on yield and composition of total particulate matter as well as on the temperature in the combustion zone of plain cigarettes. Total particulate matter and single components of the smoke can best be correlated with the dry weight of tobacco burnt in the mainstream. These figures are estimated by semi quantitative measures. The yield of dry total particulate matter is independent of tobacco moisture content if calculated on the basis mentioned above. The nicotine content of the smoke decreases with increasing moisture content of tobacco. Calculations on the where about of total nicotine suggest that nicotine is increasingly decomposed in the presence of moisture. The yield of 1,2- and 3,4-benzopyrene rises with increasing moisture content but with different slopes. The temperature of the combustion zone is independent of tobacco moisture content. The chemical and catalytic importance of moisture in smoking processes is mentioned.

Measurements of the Stamping Volume of Tobacco / Untersuchungen mit dem Stampfvolumeter
Page range: 103 - 113
Abstract
It is reported about an instrument for measuring the stamping volume of tobacco. For testing purposes, readings with various kinds of tobacco have been taken, in order to examine the dependence of the various kinds of tobacco, and, furthermore the influence of the temperature, the load on the tobacco column and of the water contents. The results will be shown on charts and graphical representations. The instrument supplies reproducible results provided that certain conditions are adhered to.

An Apparatus for the Control of Tobacco Filling Regularity of Cigarettes / Ein Gerät zum Prüfen der Füllungsgleichmäßigkeit von Cigaretten
Page range: 114 - 116
Abstract
The present paper describes an apparatus for the detection of irregularities in the tobacco filling of cigarettes. The cigarettes are charged with a defined pressure and the resultant deformations exceeding a predetermined limit are indicated automatically in number
