Displacement washing machines

By sensing the displacement of the drum, considerable advantages for the manufacturer and end users of washing machines are achieved ... 

Integration of displacement measurement in more and more washing machines can be expected in the future. 

Position/Displacement sensors can be used in active damping systems of industrial washing machines in order to compensate for vibrations coming from unbalanced drums /laundry. These can work much like a simple automotive shock absorber. 

Under alkaline conditions, 1 mol of TAED reacts with two moles of perhydroxide anion to form 2 mol of peracetic anion (Fig. 4). The residue is diacetyl ethylene diamine (DAED). The remaining two acetyl groups on DAED cannot be displaced by pefoxiae in the wash bath and this biodegradable residue is discharged from the washing machine. The mechanism of reaction is via nucleophilic attack by the perhydroxide anion and is typical of that of imides. 

Step 3 The stationary phase is saturated in nickel ions. The greenish effluent leaving the machine contains only nickel ions two times more concentrated than the entering solution. Cobalt ions are still extracted, displacing nickel ions. Step 4 End of the process — the stationary phase is saturated in cobalt ions. The machine is stopped, the dark blue stationary phase is collected, and cobalt ions are recovered by an acid wash. (From Ref. 3.)... 

Fig. 2 Removal and separation of cobalt and nickel ions by CCC. Stationary phase heptane + diethyl hexyl phosphoric acid (noted HA, concentration 0.5 Af) mobile phase aqueous solution of cobalt and nickel acetate (0.01 M each). Step 1 The CCC machine is equilibrated with water. Step 2 The ionic solution is introduced into the machine the ions are extracted into the stationary phase and the cobalt complex displaces the nickel one, which is less stable. Deionized water at pH 3 exits the column because all ions are replaced by protons. Step 3 The stationary phase is samrated in nickel ions. The greenish effluent leaving the machine contains only nickel ions, which is 2 times more concentrated than the entering solution. Cobalt ions are still extracted, displacing nickel ions. Step 4 End of the process— the stationary phase is saturated in cobalt ions. The machine is stopped the dark blue stationary phase is collected and cobalt ions are recovered by an add wash.
