Bull. Spec. CORESTA Congress, Harare 1994, p. 156, ST 6 Approaches to increase the degradation rate of cellulose acetate fibres TEUFEL E.; COULON M.FOZARD H.; WILLMUND R. Courtaulds Acetate, Coventry, UK In the recent years there has been a growing interest from the public and from the industry concerning the degradation of cigarette filters and in particular the biodegradation of cellulose acetate fibres. Numerous papers have been published on these...
CORESTA Meeting, Smoke/Technology, Utrecht, 1991, S01 Degradation of cellulose acetate filters in the environment LOWE H.M.; WHITE J.N.T. Courtaulds Acetate, Coventry, UK The growing interest in environmental matters has prompted this research into the degradability of cellulose acetate filter tips. The work was confined to studying the effects of soil burial and it falls into two parts. First, whole filter rods were...
Bull. Spec. CORESTA Symposium, Kallithea, 1990, p. 198, T11, ISSN.0525-6240 Some observations on the calibration of pressure drop standards WHITE J.N.T. Courtaulds Acetate, Coventry, UK Pressure drop testers are usually set-up using glass multi-capilliary rods which have been calibrated under specified conditions. These standard rods are commonly supplied with two calibration values, one for use with vacuum instruments and one for...
Bull. Spec. CORESTA Congress, Guangzhou 1988, p. 157, T-5 Continuous pressure drop monitoring to assess process variability BANKS A.J.; WHITE J.N.T. Courtaulds Filter Tow, Derby, UK. We have developed a method of continuously measuring the pressure drop of filter rods as they are produced on a standard rod maker. The method of measurement is based on the principles described in the earlier work of Morrison and Molins and involves...
Bull. Spec. CORESTA Symposium, Taormina, 1986, p. 105, ST11, ISSN.0525-6240 Quantitative measurement of the blooming of cigarette tow WHITE J.N.T. Courtaulds Acetate, Coventry, UK In the manufacture of cigarette filters from cellulose acetate tow, the tow has to be bloomed to separate the fibres from each other before it is wrapped in paper. The pressure-drop at constant rod weight can be used as a measure of the degree of...
Bull. Spec. CORESTA Symposium, Winston-Salem, 1982, p. 37, ST6, ISSN.0525-6240 The hardness of cellulose acetate tow during smoking WHITE N.T. Courtaulds Acetate, Coventry, UK It is known that cellulose acetate filters soften during smoking, and this has become more noticeable as filter weights have been reduced. A laboratory test has been developed to measure the hardness of a filter during smoking on a machine. A radial...
Tob.

General Cigar Co., Inc. Research Laboratory, Lancaster, Pennsylvania USA Under conditions supporting rapid growth, γ-[6-hydroxy-(3-pyridyl)]-γ-oxobutyric acid appeared to be the last major pyridine-containing intermediate formed within twelve hours by the non-blue-pigment-forming nicotine-degrading bacterial isolate No....

Lancaster, Pennsylvania USA Increased aeration provided by a more efficient shaker and baffled Erlenmeyer flasks resulted in faster growth of all six nicotine-degrading isolates. Moreover, these conditions increased both the tolerance to nicotine and its utilization by the four...
