The determined measurement values are transmitted to a control device, and from there passed on to a data storage device where they are stored.

Abstract: In the field of agriculture and aerial firefighting, some example vent systems for aircraft fluid dispersion tanks include a vent-well recessed below the top of the tank. When a gate valve assembly below the tank opens to release fluid for dispersion along the aircraft's trailing flight path, the vent system prevents a detrimental vacuum from developing within the tank. In some examples, a recessed vent exploits the Coanda effect to direct air into the tank without obstructing the pilot's view. In some examples, a low profile scoop above the vent further promotes airflow with minimal visual obstruction. In addition or alternatively, some example vent systems include a lightweight cable connecting the gate valve assembly to a spring-loaded vent. The cable pulls the vent open in response to the gate opening to release fluid. When the gate closes, the cable becomes slack, which allows the spring to close the vent.

The application channel widens towards the outlet in the first direction. A nozzle holder has a main body and two clamping plates. A material feed duct extends through the main body, leading into the inlet at a feed opening. The clamping plates, bearing on opposite nozzle body side faces, fix the nozzle body releasably to the main body. The clamping plates are separate components fixed releasably to the main body and the nozzle body, and/or the nozzle body has two nozzle plates bearing flat against one another, with at least one duct portion between the nozzle plates.

Abstract: An aerosol delivery system has a nebulizer and a humidifier providing a gas flow to the nebulizer. A controller varies humidity level of the gas flow to the nebulizer so that if the nebulizer is not operating it has about 100% humidity and it is operating the value is less to allow for the humidification effect of the nebulizer. The control may be achieved by dynamically varying proportions of flow through a dry branch and a humidification branch.
