  • peristaltic pumps in which the pump acts upon a continuous tube that extends through an inlet opening and continues through a discharge opening of the pump.
  • This arrangement is particularly beneficial for use with electrostatically charged fluids or particles that are being pumped toward the discharge nozzle 24, because the tubing can electrically insulate the pump from the charged benefit composition.
  • an alternative pumping device could be used, if desired, such as a spring-actuated pumping mechanism.

  • the temperature will tend to continually increase within the drying chamber. Once the heating element is turned off, then the temperature will begin to decrease (although there could be some overshoot).
  • the heating element may be turned on and off several times, in which case a temperature versus time graph would have the appearance of a sawtooth waveform, in which an increasing slope (assuming temperature is the Y-axis and time is the X-axis) would occur when the heating element is turned on, and a decreasing slope when the heating element is turned off.

  • a volatile material such as certain perfumes
  • One way to detect this is to know when the heating element is actually energized or not, and an integral control device that is mated into the dryer's heating element controller would have knowledge of that status for the heating element, and thus could easily prevent any dispensing or application of the fabric treatment composition until after the heating element had been de-energized at the end of a heating cycle (as opposed to during the plateau region of the heating cycle, when the heating element could turn off, but also could later turn back on).
  • One way of determining the end of a heating cycle would be to determine the maximum and minimum temperatures that occur during the sawtooth waveform portion of the heating cycle, also referred to above as the "plateau region.” If, for example, the internal temperature of the dryer's chamber will rise to a maximum temperature T MAx , and then fall to a momentary "minimum” temperature that is about 10-15°C lower than T MAX , then the controller for the dispensing apparatus could determine when to begin applying the fabric treatment composition, which is after the dryer's internal temperature falls below maximum temperature T MAX , less the 10-15°C "minimum” temperature.
