Abstract
Abstract An apparatus for mixing and feeding a volatile liquid, such as liquid ammonia, with a nonvolatile material, such as a fabric finisher; the method comprising the steps of feeding the liquid to a mixing vessel and, by volatilizing a portion of the liquid, cooling the vessel and, while continuing to feed the liquid and after the cooled liquid has reached a predetermined level in the vessel, adding to the liquid a measured amount of nonvolatile material, continuing the liquid feed until the liquid level reaches the measured amount, agitating the liquid and material and, as the liquid volatilizes, adding additional of such liquid to maintain the liquid level at the measured amount; the apparatus comprising a mixing tank having a cover, a coolant coil in the mixing tank, first feed means having a valve for feeding a volatile liquid to the tank, second feed means having a valve for feeding a nonvolatile material to the tank, a float and switch in the tank for controlling the liquid feed valve, a float and switch in the tank for controlling the nonvolatile material feed valve, a discharge line for discharging the mixed material from the tank to a trough in a fabric treatment chamber, a valve in the discharge line, electrical means for opening and closing the valve in the discharge line and for closing the liquid feed valve when the discharge valve is open and for closing such liquid feed valve when the discharge valve is open, the floats in the tank opening and closing the liquid feed and material feed valves when the liquid in the tank is at pre-set levels.
