Abstract: A method is disclosed for remote control wherein coded commands are transmitted from a transmitter to a receiver. A respective time interval between a first energy impulse starting the transmission and a second energy impulse concluding the transmission is utilized as the coding which characterizes the individual command. Time intervals rigidly allotted to the individual commands are selected differently such that the differences formed by subtracting the time intervals have at least partially different values in relation to one another. The remote control is particularly useful for remote control hobby equipment.

Abstract: This invention relates to a tobacco treatment in which the perceived strength of tobacco smoke is improved by treatment of acidic tobacco with a material which remains essentially inactive until the tobacco is burned. The treatment is particularly effective on acidic tobacco to be employed in high filtration cigarettes which deliver reduced amounts of tar and nicotine.
