Abstract: Automated control system status information is displayed to a system operator by storing in electronic memory first fields of graphic indicia for generating at an operator display graphic representations of system conditions to be monitored and second fields of text indicia associated with the graphic indicia. The second fields of text indicia are stored in sets of separate sub-fields in each of two text languages, with each set in each sub-field being associated with a specific first field of graphic indicia. The system operator may alternately select between the sets of sub-fields of text indicia in such a way that the text fields displayed simultaneously with the graphic fields at the operator status display are all in one or the other of the two text languages.

Abstract: A tray sortation system particularly suited to the handling of tires which are at elevated temperature and tend to adhere to the tray which comprises a plurality of interconnected carriage assemblies movable along a track, each carriage assembly including a tray which is tilted on an axis generally parallel to the axis of travel. Each tray is provided with a fixed roller mounted along the center line of the tray and extending in the direction of movement of the tray. Each carriage assembly further includes a pair of rollers attached thereto and adapted to extend through openings in the tray when the tray is tilted thereby breaking any contact formed between the tire and the tray and insuring a free gravitational discharge of the tire from the tray at an assigned discharge location.
