Abstract: A system is described for carton serialization on a high-speed production line. The system includes conveying apparatus. A printer prints a unique character string on each piece of feed stock to uniquely identify each assembled carton. Folding and gluing apparatus are operatively associated with the conveying apparatus for selectively gluing and folding feed stock to form assembled cartons. An analysis apparatus monitors operation of carton assembly. A rejection device selectively removes defective assembled cartons from the conveying apparatus. A control system is in operative communication with the sensor, printer, folding and gluing apparatus, the analysis apparatus and the rejection device. The control system stores machine operating parameters in a database. The control system controls the printer to print the unique character string on each piece of feed stock responsive to the sensor and storing the unique character string and production time for each carton produced in a database.

Abstract: An induction-displacement neutral wall air terminal unit includes a housing defining a supply airflow path, a connected return airflow path, and a heating airflow path separated from the supply and return airflow paths by at least one interior wall. The unit also includes a plurality of induction-type nozzles located within the supply airflow path, that are deliver a ventilation air flow stream into the supply air flow path. The nozzles induce a return air flow stream through the return air flow path that mixes with the ventilation air flow stream to form a supply air flow stream delivered to a supply air outlet. A heating element is disposed within the heating airflow path to heat air within the heating air flow path. A plurality of fans may be placed within the heating airflow path to increase the overall heating capacity of the unit.
