Abstract: A gearmotor assembly for use with a conveyor system has a rotatable conveyor roller extending laterally between spaced conveyor side rails. The gearmotor assembly includes an electric motor with a rotatable motor output shaft. The gearmotor assembly further includes a gear train drivingly connected to the motor output shaft. The gear train includes a train output shaft axially offset from the motor output shaft, with the train output shaft being drivingly connectable to the conveyor roller, so that rotation of the motor output shaft produces corresponding rotation of the conveyor roller.

Abstract: A continuous ink jet printing system for use with a hot-melt ink, comprising a supply chamber for retaining said ink in a liquid form, means for applying heat to the ink in said chamber to maintain said ink in a liquid form, means for conveying said ink in liquid form from said chamber to a printhead for projection toward a substrate to be marked, catcher means for collecting any of said ink that is not directed to said substrate, means for returning the collected ink as a liquid to the supply chamber, and means for maintaining the ink as a liquid while it is being returned to said supply chamber.Also disclosed is an ink jet nozzle for use in printing hot-melt inks at elevated temperatures comprising an ink jet nozzle body, a transducer, means for acoustically coupling said transducer to said body, and means for maintaining said transducer acoustically coupled to said body at elevated temperatures.

Abstract: A thermoelectric heat exchanger includes a first finned heat sink which includes at least two planar regions, at least two second heat sinks, each shaped to fit a respective one of the planar regions. At least two sets of thermoelectric cooling elements are provided, each set made up of three cooling elements arranged in a triangular pattern in a respective one of the planar regions between the first heat sink and the corresponding second heat sink. The cooling elements are connected together in series within each set and an electric voltage is applied in parallel across each of the sets of cooling elements. The second heat sinks are secured to the first heat sink to create a low thermal resistance contact between the cooling elements and the heat sinks, with each of the cooling elements establishing at least point contact with both of the respective heat sinks.
