Abstract: A wound dressing that releases, via hydrolysis and in a controlled manner, acetic acid when subjected to body temperatures and moisture, and is made from a cellulose ester substrate with a partial solvent thereon.

Abstract: A test apparatus includes an optical displacement transducer for sensing deformation of the cigarette filter responsive to a predetermined load applied transverse to the filter during simulated smoking of the cigarette, and a barcode laser scanner for sensing relative movement of a charline along a tobacco rod of the burning cigarette during simulated smoking. The optical displacement transducer thus produces a filter hot collapse signal, while the barcode laser scanner produces a tobacco consumption signal. A processor, such as a microprocessor operating under stored program control, samples the hot collapse signal and the tobacco consumption signal to generate a series of respective data points. A display is operatively connected to the processor for generating a graphical representation of at least one of the hot collapse signal and the tobacco consumption signal as a function of time, based upon the respective sampled data points.

Abstract: Cellulose ester microparticles with unique properties are made by a process having the following steps:(a) dissolving a cellulose ester in a liquid comprising a solvent for the cellulose ester and a non-solvent for the cellulose ester, thereby forming a dope;(b) spheronizing the dope thereby forming fine droplets of the dope;(c) dropping the droplets for a finite amount of time; and(d) precipitating the droplets in a bath containing a precipitant.

Abstract: A filter for a smoking article includes: a flavorant; a hollow fiber made of a thermoplastic, the flavorant dispersed in the thermoplastic; and a filter plug in which the fiber is embedded. Additionally, the hollow fiber may be sheathed with a layer of cellulose acetate.
