Abstract
Abstract 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
130 words
Apparatus for smoking cigarettes and collecting the condensable components of the smoke produced by burning cigarettes for predetermined intervals, comprising a movable support, at least one cigarette mounted on the support, means for effecting periodic movement of the support to move said cigarette thereon to and away from a predetermined position, a chamber maintained at subatmospheric pressure, a conductor having a part in continuous communication with the chamber and a part periodically movable with said support to said position and into intimate communication with said cigarette on the support at said position, and means for effecting synchronous movement of the support and the movable portion of the conductor to effect movement of the movable portion of the conductor to said position each time said cigarette is moved to said position.
Claim 2
Dependent Claim
130 words
Apparatus for smoking cigarettes and collecting the condensable components of the smoke produced by burning cigarettes for predetermined intervals, comprising a movable support, at least one cigarette mounted on the support, means for effecting periodic movement of the support to move said cigarette thereon to and away from a predetermined position, a chamber maintained at subatmospheric pressure, a conductor having a part in continuous communication with the chamber and a part periodically movable with said support to said position and into intimate communication with said cigarette on the support at said position, and means for effecting synchronous movement of the support and the movable portion of the conductor to effect movement of the movable portion of the conductor to said position each time said cigarette is moved to said position.
Claim 3
Dependent Claim
57 words
Apparatus according to claim 1 wherein the support has a plurality of holders thereon for holding a plurality of cigarettes, a single manifold at said predetermined position movable relative to the support from a retracted position to a position of intimate communication with the cigarettes, the conductor being flexible and communicatively connecting the chamber to the manifold.
Claim 4
Dependent Claim
89 words
Apparatus according to claim 2, wherein the support is rotatable about a vertical axis and the means for effecting intermittent rotation of the support comprises a motor, kinematic means for drivably connecting the motor to the support, a switch operable to stop the motor, a cam on the support operable, by engagement with the switch, to effect operation thereof, at intervals corresponding to the distance between holders, and a brake operable to bring the support to a stop without overrun, operation of said brake being effected by said switch.
Claim 5
Dependent Claim
56 words
Apparatus according to claim 3, comprising a timer motor adapted to operate at predetermined intervals, said timer motor having an output shaft connected to said manifold and being operable following operation of the brake to effect operation of the means for moving the manifold into and out of communicative relation with the holder on the support.
Claim 6
Dependent Claim
86 words
Apparatus according to claim 1, wherein the support is rotatable and there are a plurality of cigarette holders thereon at spaced intervals for movement with the support along a closed path relative to said predetermined position, so that a cigarette on a holder which has been moved out of communicative relation with the movable part of the conductor at said position is returned to said communicativE position therewith at the end of a predetermined interval corresponding to the sum of the intervals between holders minus one.
Claim 7
Independent Claim
118 words
The method of collecting condensable components of smoke produced by burning a cigarette at predetermined time intervals, comprising igniting one end of the cigarette, placing the other end of the cigarette in communicative relation with a chamber maintained at a subatmospheric pressure, for a period of time corresponding to said predetermined time intervals for drawing smoke from said cigarette into said chamber, removing said other end of the cigarette from said communicative relation with said chamber for a period of time corresponding to a selected interval for cooling between periods of burning and thereafter continuing to move said other end of the cigarette into and out of communicative relation with said chamber until the cigarette is substantially consumed.
Claim 8
Independent Claim
118 words
The method of collecting condensable components of smoke produced by burning a cigarette at predetermined time intervals, comprising igniting one end of the cigarette, placing the other end of the cigarette in communicative relation with a chamber maintained at a subatmospheric pressure, for a period of time corresponding to said predetermined time intervals for drawing smoke from said cigarette into said chamber, removing said other end of the cigarette from said communicative relation with said chamber for a period of time corresponding to a selected interval for cooling between periods of burning and thereafter continuing to move said other end of the cigarette into and out of communicative relation with said chamber until the cigarette is substantially consumed.
