摘要:
A smoking machine for smoking a smoking article is disclosed. The smoking machine comprises one or more electrochemical cells for analyzing the composition of a smoke stream from the smoking article. This can allow a gas or vapor phase chemical to be analyzed directly in real time without the need for pre-conditioning or preparation.

An ignition system for a smoking machine is disclosed. The ignition system comprises an ignition head (12) for igniting one end of a smoking article which is held by a smoking machine, a sensor (18, 20) for detecting a distance between the end of the smoking article and the ignition head (12) in a direction parallel to the axis of the smoking article, and control means (21) for automatically adjusting ignition conditions in dependence on the detected distance. The sensor (18, 20) is arranged to detect the distance across a range of offset positions of the end of the smoking article in a plane perpendicular to the axis of the smoking article, which range is greater than the width of the end of the smoking article.
摘要:
The present invention provides an ignition system for a smoking machine, comprising a heat source (2) that is adapted for emitting heat for igniting one end of a smoking article which is held by a smoking machine; an automatic sensor (3, 4) which is adapted for detecting the position of said end of the smoking article; and control means in communication with said sensor (3, 4), which are adapted for automatically adjusting the operation of said heat source (2) and/or for automatically adjusting relative movement of said heat source and/or of said article, depending on the position of said end as detected by said sensor (3, 4), such as to enable successful ignition of said end by said heat source. The invention further provides a kit of components for forming an ignition system in accordance with the invention, and a smoking machine comprising an ignition system in accordance with the invention.

Process and apparatus for preparing a plurality of filter holders for use in a smoking machine both include assembling a plurality of such filter holders, each holder having upper and lower portions constructed and arranged for fitting engagement with one another. A filter element is placed between the upper and lower portions of each filter holder, and each holder is loosely assembled by fitting the upper and lower portions together with the filter element therebetween. The loosely assembled filter holders are placed on a portable tray having a plurality of individual compartments, one for each loosely assembled filter holder. The portable tray is placed within a press for pressing the filter holder portions together to thereby simultaneously seal the upper and lower portions of each filter holder together with the filter element therebetween.

An apparatus for marking cigarettes with a mark to terminate operation of a smoking machine includes a jig for holding at least 40 cigarettes and maintaining the cigarettes' position with a seam side of each cigarette facing a given direction. A scannable laser having a laser light output at an intensity and frequency makes a scorch mark on the seam of each cigarette paper without perforating the cigarette paper. A software control system for the scannable laser is programmed to cause the laser to scan over the cigarettes in the jig to etch and make a circumferentially-oriented line segment mark no longer than 1.5 millimeter and no wider than 0.5 millimeter on the cigarettes at a predetermined position along the length of the cigarettes.
摘要:
An apparatus for simulating a human smoking a smokable object which comprises an inhaling device for drawing smoke from the object and a motor which is coupled to the inhaling device for driving the inhaling device. The apparatus further comprises a control circuit for controlling the operation of the motor. The control circuit includes a circuit for receiving an analog signal corresponding to a human draw profile of the smoking of the object, a converter coupled to the receiving circuit for converting the analog signal to a pulse signal and a switching device for applying the pulse signal to the motor for controlling the operation of the motor.
摘要:
An apparatus for delivering accurately metered volumes of a fluid at accurately spaced intervals. A pumping assembly including a cylinder, piston and fluid valving means are driven through a first cam which controls the volume of fluid pumped and a second cam, driven by the same synchronous motor used to drive the first cam, is used to control the engagement and disengagement of the first cam and hence to control the intervals between pumping cycles. When used as a smoking machine for animal tests, an additional air inhalation valve is provided and the apparatus is arranged to be connected to a gas reservoir attachable to the animal in a manner to create minimum interference with his normal breathing.

A smoking machine includes a pair of parallel disks alternately rotatable about a common axis and each provided with a number of holders for cigarettes or other smokable articles. Means is provided for automatically lighting the cigarettes. The holders are spaced apart at equal intervals in circular paths respectively centered on the axis of the disks. A shuttle valve is mounted at a smoking station between the two disks and adjacent to each to receive a continuous stream of smoke from the cigarettes in sequence and channel it to a desired location, at which there may be, for example, a holder for an experimental animal. The valve shuttles between the two disks to take a puff on each cigarette as it arrives at the smoking station. The cigarettes carried on one disk are thus puffed alternately with those carried on the other. ''''Reverse puffing'''' is employed: i.e., chambers are placed over the lighted ends of the cigarettes and pressurized, so that the smoke is delivered at atmospheric pressure. While a puff is being taken on any given cigarette on one of the disks at the smoking station, the other disk is rotated by an indexer to bring the next cigarette to the smoking station, which is puffed in the same way. The process continues for a number of rotations of the disks, until the cigarettes are smoked to the desired extent, whereupon they are automatically ejected.
摘要:
An apparatus comprising a holder for one or more cigarettes, a low pressure condenser and a conductor connecting the holder to the condenser whereby large scale collection of the condensable components of the smoke from one or more cigarettes may be obtained for the purpose of analysis to determine the amount of such components inhaled by a cigarette smoker.
