A conveyor for testing successive plain or filter cigarettes or other rod-shaped smokers' products having non-circular (such as oval) cross-sectional outlines employs a rotary drum-shaped conveyor for sidewise transport of smokers' products toward, through and beyond a station where the products are tested by streams of a gaseous fluid entering the products at one axial end and issuing from satisfactory products at the other axial end. The end portions of the products are sealingly received in complementary sockets of elastically deformable sealing sleeves which are connected to their tubular fluid-conveying carriers in a manner to ensure that each sleeve remains in a selected position for optimum testing of the products. For example, each sleeve can be form-lockingly coupled to its carrier in such a way that the sleeve is held against any appreciable angular and/or axial movement relative to the carrier when the conveyor transports smokers' products but that the sleeve can be detached from the carrier, in response to adequate deformation, for the purpose of inspection, cleaning and/or replacement.

A flow reversal valve for a tubular fluid flow set comprises at least four tubular branches and a tubular loop. The tubular loop separately connects with each of the tubular branches at ends thereof, the tubular loop having collapsible, clampable tube sections between connections with the branches. At least some of the tubular branches connect at a transverse, third dimensional angle to the tubular loop, either directly, or through a substantially rigid, angular bend in the blood flow tubing adjacent to the tubular loop.

A cigarette extinguishing device, including a tubular fluid receptacle configured to be disposed within a filter of a cigarette, the fluid receptacle having enclosed therein sufficient fluid to extinguish the cigarette, the fluid being under pressure from compressed air within the fluid receptacle, a diaphragm disposed at an end of the tubular fluid receptacle, the diaphragm being configured to be ruptured by at least one of pressure and heat and being more susceptible to pressure and heat than side walls of the tubular receptacle, and a tube connected to the diaphragm and extending through a tobacco region of the cigarette until a distal end of the cigarette, wherein, when the diaphragm is ruptured, the fluid flows from the fluid receptacle via the tube to a burn region of the cigarette, thereby extinguishing the cigarette.
