Abstract: A heat exchanging device absorbs heat from a heat source, in the form of waste fluid, and exchanges the absorbed heat to an object which benefits from warming. The heat exchanging device is coupled to a first structure, the combination of the heat exchanging device and the first structure forming a passage for the waste fluid to flow. Within the passage, absorption fins absorb heat from the waste fluid. The device is also engaged with a second structure which contains the object which benefits from warming. The heat absorb by the fins and the remaining body of the heat exchanging device is exchanged to the second structure, which in turn exchanges the heat to the object contained within the second structure. The heat exchanging device exchanges the heat from the waste fluid to the object in a simple and cost effective manner.

Abstract: Can ends are ejected from a tool station by a lifter ring and air currents in an ejector chute provided by a curved nozzle assembly adjacent an opening in the lower edge of the chute. It entrains can ends in air current across the die station and over a knife edge in the lower opening of the chute. The lower wall of the chute is positioned on top of the blanking die during the can end entrainment. The punch assembly moves down through the lower opening and through a larger opening in the chute. After can end clears the tooling and continues down the chute with air streams that are augmented by nozzles in the upper wall, the chute is lifted. Double-acting cylinder actuators lift the chute. Side walls of the chute taper inwardly to align the can ends for precise release from the discharge end. Sensor emitters sense passage of the can ends. Solenoid valves control application of fluid pressure to opposite ends of the actuator cylinders.
