Abstract: A textile drying machine comprises a tank for receiving textiles with a spindle inside the tank for supporting the textiles, and a solid-state radio frequency generator. The generator is connected to the spindle and the tank is earthed so that when the generator is operated an oscillating electric field is generated between the spindle and the tank, and hence applied to textiles on the spindle. The electric field heats water molecules in the textiles by molecular vibration so that evaporation occurs, and the water vapor is removed from the tank by an extractor fan. The machine may also be used to dye the textiles prior to drying, thus providing an integrated dyeing/drying machine.

Abstract: A method and apparatus for treating a load with dyeliquor includes a pump/motor set, a dyeliquor circulating system holding the load and directing all the dyeliquor pumped by the pump to flow through the load, a motor current measurement device to measure current consumed by the electric motor while driving the pump, and a throttle valve adjusted to create a flowrate of the dyeliquor through the dyeliquor circulating system based on the current measured by the motor current measurement device. The flowrate of the dyeliquor increases linearly in proportion with increases in the current consumed by said electric motor while driving said pump. The apparatus also has a low system resistance to fluid flow allowing variations in a load resistance of the load to fluid flow to produce corresponding variations in the current of the electric motor measurable by the motor current measurement device.
