A field olfactometer includes a mixing chamber connected to a mask. A sample flow path is defined through the olfactometer as is a diluent flow path. The sample flow path extends from a sample air inlet to a sample air outlet which is open to the mixing chamber. The diluent flow path extends from a diluent air inlet to a diluent air outlet which is also open to the mixing chamber. The sample flow path and diluent flow path are isolated from one another so that the sample air flowing through the sample flow path and diluent air flowing through the diluent flow path cannot mix until the two streams of air exit their respective flow path and enter the mixing chamber where the two streams mix thoroughly prior to reaching the mask. The diluent flow path includes a filter medium to remove odor-causing chemicals from ambient air drawn through the diluent flow path. A flow indicator arrangement provides a suitable indication when the flow rate at one or more points in the olfactometer reaches a predetermined value corresponding to a target dilution of diluent air to sample air.

An apparatus for attaching a reclosable fastener to a web of flexible material primarily intended for use with a host packaging machine to form a reclosable container. The attaching apparatus is operatively connected to and driven by a programmable motor and function controller in cooperative relation with the host machine and guides the web of flexible material from which the containers will ultimately be formed along a first path through the attaching apparatus. A supply of reclosable zipper-type fasteners is also provided, and the fasteners are guided along a second path of the apparatus. Individual zipper-type fasteners are removed from the fastener supply path and disposed in juxtaposition to a segment of the flexible material in overlying relation to a cut which has been formed through a predetermined segment of the flexible material. The individual fastener is then sealed to the flexible material in overlying, surrounding relation to the cut, and the web, with the reclosable fastener attached thereto, is then passed to the host packaging machine for forming, filling, sealing and separating a reclosable container.
