Claim 4

An apparatus for controlled introduction of odors into an auditorium comprising: a. an air injection system having an air duct for receiving a cartridge containing a measured dose of the odorous substance, the received cartridge constituting a part of the duct, b. a number of injection nozzles for introducing the odor, c. means connecting the duct to the nozzles, d. an air ventilization system for effecting an air renewal in the auditorium at least 20 times per hour. e. a by-pass duct connected with the part of the duct which receives the cartridge, said by-pass duct being constructed to offer an air flow resistancE of substantially the same magnitude as the air flow resistance in a cartridge, f. valve means in the ducts for enabling a selective air flow through the cartridge or through the by-pass duct, g. a plurality of duct sections connected in parallel with the by-pass duct and each being adapted to receive a cartridge, h. valve means for enabling a selective air flow through the by-pass duct or any desired duct sections, and i. a branch means in the air duct comprising a suction box having a plane external wall surface mounted at the intake end of the air duct, the suction box having a plurality of holes each adapted to receive the terminal face of an associated cartridge and sealing means for sealing the cartridge and suction box, whereby a number of cartridges can be mounted on the suction box with the sealing means secured to it by means of the partial vacuum present in the duct during operation.

Claim 5

An apparatus for the controlled introduction of odors into an auditorium comprising: a. an air injection system having an air duct for receiving a cartridge containing a measured dose of the odorous substance, the received cartridge constituting a part of the duct, b. a number of injection nozzles for introducing the odor, c. means connecting the duct to the nozzles, d. an air ventilization system for effecting an air renewal in the auditorium at least 20 times per hour, and e. further including a chamber with side wall plates, the air duct serving to accommodate the cartridge comprising an intake and a discharge line which are positioned opposite each other, and are each connected to one of two mutually connected plates having plane parallel lateral surfaces that are facing each other, the plates form side walls in the chamber which are sealed apart from the connection to the intake and discharge lines, and wherein a drive is fitted within this chamber for moving a plurality of cartridges such that a single one of these at a time can be brought into a position in which it forms a connection between the intake and discharge line while the others occupy positions in which they are sealingly fitted to the side walls of the chamber and are sealed at both ends, and a wall of the chamber having a closable aperture connecting the side walls for introducing and removing a cartridge.
