Filed:

Sep 18, 2001

Appl. No.:

09/954437

Inventors:

Stanislav M. Snaidr - Mississauga, CA
Robert E. Becker - Wayne PA

Assignee:

Rothmans, Benson Hedges Inc. - Ontario

International Classification:

A24B 1518

US Classification:

131334, 131365, 131360, 131207, 162139, 1621815

Abstract:

A low sidestream smoke cigarette comprises a conventional tobacco rod and a non-combustible treatment material for the rod. The treatment material has a porosity less than about 200 Coresta units and a sidestream smoke treatment composition. The treatment composition comprises, in combination, an oxygen storage and donor metal oxide oxidation catalyst and an essentially non-combustible finely divided porous particulate adjunct for said catalyst. In addition, the invention provides a low sidestream smoke cigarette unit that comprises a cigarette with conventional cigarette paper surrounding a conventional tobacco rod and a non-combustible treatment material surrounding and being substantially in contact with the conventional cigarette paper. The non-combustible treatment material comprises a sidestream smoke treatment composition, wherein the non-combustible treatment material has a porosity less than about 200 Coresta units and the treatment composition comprises, in combination, an oxygen storage and donor metal oxide oxidation catalyst and an essentially non-combustible finely divided porous particulate adjunct for said catalyst.

Abstract:

A method and apparatus for removing excess coating material from a honeycomb body of a catalytic converter. The coated honeycomb body is mounted on an eccentric tappet and is rotated around a first rotational axis with a first rotational frequency such that the distance from the center of gravity of the honeycomb body to the first rotational axis is at least 1. 5 times the length of the honeycomb body. The honeycomb body is further rotated around a second rotational axis even out the coating material and provide a more uniform coating surface.

International Classification:

US Classification:

131/365000, 162/139000

Abstract:

A cigarette sidestream smoke treatment material made from a sheet of non-combustible active components provides a porous structure capable of treating sidestream smoke. The treatment material, as used in combination with a cigarette, provides a low sidestream smoke emitting cigarette unit. The material has a porosity which encourages a conventional free-burn rate of a conventional cigarette. The material may comprise a sorbent capable of sorbing components of the sidestream smoke, and an oxygen storage component which releases oxygen at free-burn rate temperatures to ensure that conventional free-burn rate is maintained and to enhance the oxidation treatment of the adsorbed non-aqueous components. Preferably, an oxidation catalyst is included in the material and most desirably the oxygen storage component may also function as the oxidation catalyst. Particularly preferred materials which perform the dual function are oxides of cerium.

Appl. No.:

Inventors:

Robert Becker - Wayne PA, US

International Classification:

B05D001/00

US Classification:

427/008000

Abstract:

A method for applying washcoat dispersion to catalytic converter support bodies. The temperature of the washcoat dispersion and the temperature of the support body are controlled during the coating process. Preferably, the temperatures are substantially equal. The generally equal temperature results in an equal flow behavior of the washcoat dispersion and therefore results in a generally uniform depth of coating layers. Further, such a small temperature tolerance increases the consistency of the quality of the washcoat coating with regards to mass production of support bodies because the viscosity behavior of the washcoat dispersion is highly predictable.
