Abstract:
Disclosed is a smoking article containing a rod containing a smokable composition, an optional wrapper for the rod, and at least one polymer or oligomer comprising monomer units of a polycarboxylic acid ester disposed on or in the rod, the wrapper, or both. The polycarboxylic acid ester contains an acid moiety having at least two carboxylic groups, and at least two alcohol moieties independently selected from those corresponding to a cycloalkyi alcohol or an aryl alcohol. The cycloalkyi alcohol or aryl alcohol is a flavorant, or chemesthetic agent, or both. In addition, a method for the controlled release of these flavorant or chemesthetic agents is described, which comprises pyrolyzing at least one polymer or oligomer.
Abstract:
Obal kuráckého výrobku, v nemž je umísten tabák, obsahuje celulózový plošný materiál a fosforecnan horecnato-amonný, nebo jeden z jeho hydrátu jako plnivo pro úcinné snížení obsahu plynných složek v kouri vytváreném spalováním ci pyrolýzou kuráckého výrobku, pricemž plynná složka obsahuje alespon jeden aldehyd o nízké molekulové hmotnosti. Predmetem vynálezu je i cigareta, která zahrnuje tabákovou rohož obklopující tabákovou tycku, papírový obal obklopující tabákovou rohož a volitelne filtr na jednom konci cigarety, pricemž tabáková rohož obsahuje tabák alespon s jedním plnivem pro úcinné snižování obsahu plynných složek v hlavním proudu koure vytváreného spalováním, ci pyrolýzou cigarety.
Abstract:
Methods and apparatuses for cleaning an electrical lighter are provided. A sleeve, e.g., ceramic or metal, surrounds the heater fixture, and a resistive heating element is in thermal proximity with the sleeve. The resistive heating element is either a dedicated element or the cigarette heating elements. The sleeve serves as a aerosol barrier and condensate accumulator to protect other components. Periodically, e.g., substantially contemporaneously with a battery recharge, the heating element is activated to thermally liberate condensates deposited on the sleeve during smoking and also heats, and thereby cleans, other components. Also, a cleaning element is optionally inserted into the cigarette receptacle of the electrical lighter or placed at the exit thereof to absorb, attract and/or catalytically break down the thermally liberated condensates. The sleeve also directs a desired flow path for drawn air within an electrical lighter toward the cigarette.
Abstract:
This invention provides smoking compositions which contain a novel beta -hydroxy-carboxylate flavorant-release additive. Under cigarette smoking conditions, a combustible filler and/or paper wrapper additive such as calcium bis(2,2-diethyl-3-hydroxy-4-phenylmethylenedecanoate) pyrolyzes and releases alpha -hexylcinnamaldehyde as a volatile flavorant component of the cigarette smoke.

Abstract:
A main aspect of this invention is the provision of a liquid medium for scrubbing contaminants from an environmental gas-phase. Toxic chemicals such as phosphine and arsine are removed from a gas-phase stream by contacting the gas-phase stream with an aqueous medium which oxidizes the contaminants to water-soluble or water-dispersible type derivatives. The aqueous medium has a content of redox ingredients illustrated by compounds such as silver nitrate, hydrogen peroxide, sodium tungstate, and sulfuric acid.
