Another example is a dilution refrigerator, where a mixture of 3 He and 4 He forms a phase boundary in a mixing chamber and can cool down to a few millikelvins.
22.
First the ingredients are measured and added to a Pre-mixer , and then they are transferred to a mixing chamber which finalizes the mixing process and obtains a homogeneous mass.

Defeating the militia there, Batman confronts Scarecrow in the central mixing chamber, where the villain informs Batman that Barbara Gordon has been captured, before locking the hero inside the imploding facility.
24.
The mixing chamber, due to its exclusive construction, utilizes centrifugal force to insure a perfect mixture between the gas and air, which in turn provides complete combustion, thus preventing dangerous fumes.
25.
After the gas leaves the mixing chamber it passes into a distribution chamber whose shape is such that an equal amount of gas passes into each jet, giving uniform flame height and also intensity.
26.
Inlet and exhaust manifolds are on the right hand side of the block . the inlet manifold's two branch mixing chamber has a vee-shaped piece inside which is heated by exhaust gases.
27.
The heat necessary for the dilution is the useful cooling power of the refrigerator, as the process of moving the 3 He through the phase boundary is endothermic and removes heat from the mixing chamber environment.
28.
From 1927 he worked at Ganz Rt, where he helped to develop diesel engines, of which the first few pieces were made with single and double cylinders; later, the 4-and 6-cylinder four-stroke versions were developed, without compression and with mixing chamber.
29.
The automatic inlet valves of earlier Anzani engines, opened by atmospheric pressure and closed by valve springs were retained, but fuel was fed from a mixing chamber in the crankcase via inlet tubes placed at the rear of the engine to avoid cooling of the mixture by the oncoming airflow.
30.
In the mixing chamber, two phases of the 3 He 4 He mixture, the concentrated phase ( practically 100 % 3 He ) and the dilute phase ( about 6.6 % 3 He and 93.4 % 4 He ), are in equilibrium and separated by a phase boundary.
