摘要:
The invention relates to a device for producing consumible ice cubes, comprising at least one immersion element (46) provided with a conductive ice adhesion surface (46a), and a refrigerating appliance (34). The immersion element (46) is designed to be immersed, by the ice adhesion surface (46a) thereof, into a consumible liquid (58). The refrigerating appliance (34) is structurally connected to the immersion element (46) and comprises a pre-defined heat transport device for cooling down at least the ice adhesion surface (46a) to a freezing temperature of the liquid (58) such that, when the immersion element (46) is immersed, the liquid (58) located in the close surroundings of the ice adhesion surface (58) can be frozen, and an ice cube can be formed from some of the liquid (58) on the ice adhesion surface (46a).

摘要:
This invention provides a device and method for rotating magnetically inducible particles suspended in a fluid by rotating a multidirectional magnetic field through the suspended particles. A rare earth magnet is positioned adjacent to the suspended particles and oriented such that the axis of a magnetic field generated by the magnet passes through the suspension. The magnetic flux lines of the magnet's field radiate in multiple directions through the suspended particles, them to form long multidirectional chains. The magnet and the chains of suspended particles are rotated with respect to one another, the axis of the rotation being approximately parallel to the magnetic axis of the multidirectional magnetic field. This causes the particle chains to rotate about the magnetic axis, thus mixing the fluid.
