Abstract: An apparatus for collecting samples of smoke components from predetermined segments of drawn smoke during a predetermined time interval is disclosed. The apparatus includes a smoking machine for drawing successive individual puffs of smoke from a cigarette and for providing a predetermined path of travel for drawn smoke. The particulate matter of the drawn smoke is collected on a filter pad positioned on a movable stage for providing relative movement between the filter pad and the path of travel of the drawn smoke. Advantageously, the filter pad is moved transversely relative to the path of travel of the drawn smoke. A method for collecting samples of smoke components of drawn smoke is also provided.

Abstract: Flavor delivery articles employ an electrical resistance heating element and an electrical power source to provide a flavored aerosol. The articles advantageously comprise a disposable portion and a reusable controller. The disposable portion normally includes a flavor substance and an air permeable resistance heating element having a surface area greater than 1 m.sup.2 /g, which usually carries an aerosol forming substance. The reusable controller normally includes a puff-actuated current actuation means, a time-based current regulating means to control the temperature of the heating element, and a battery power supply.

Abstract: Smoking articles employ an electrical resistance heating element and an electrical power source to provide a tobacco-flavored smoke or aerosol and other sensations of smoking. The smoking articles advantageously comprise a disposable portion and a reusable controller. The disposable portion, which may be a cigarette, normally includes (i) an air permeable resistance heating element having a surface area greater than 1 m.sup.2 /g, which usually carries an aerosol forming material, and (ii) a charge or roll of tobacco. The reusable controller normally includes a puff-actuated current actuation means, a time-based current regulating means to control the temperature of the heating element, and a battery power supply.

Abstract: Drug delivery articles employ an electrical resistance heating element and an electrical power source to provide a dose of a drug in aerosol form. The articles advantageously comprise a disposable portion and a reusable controller. The disposable portion, normally includes a drug and an air permeable resistance heating element having a surface area greater than 1 m.sup.2 /g, which usually carries an aerosol forming material. The reusable controller normally includes a puff-actuated current actuation means, a time-based current regulating means to control the temperature of the heating element, and a battery power supply.

Abstract: Apparatus for performing analysis of a slurry including solid particles of elements in a liquid suspension has a container for receiving a sample of the slurry to be analyzed, and a conveyor for moving the container to a location at which the analysis is to be performed. A sampling probe is to be introduced into the slurry sample to perform the analysis. A separate probe is adapted to ultrasonically agitate the slurry sample to keep the solid particles in suspension. The agitating probe is automatically introduced into and withdrawn from the container in synchronism with the movement of the container into the desired location and immediately prior to the introduction of the sampling probe into the slurry sample.
