Abstract: An installation for continuous production of liquid ice from a solution, including a circulation tank, a pump, a refrigeration circuit for cooling solution passing through at least one tubular element, causing the formation therein of ice crystal nuclei and small pure ice crystals, a liquid separator-regenerative heat exchanger, a crystal growth vessel into which the cooled solution containing ice crystal nuclei and small ice crystals is discharged, and an ice separator fed from the ice crystal growth vessel, in which pure ice crystals are separated from concentrated solution which is returned to the circulation tank, the pure ice crystals being continuously discharged from the ice separator. A method for continuous production of liquid ice is also described.

Abstract: There is provided a device and a method for continuous casting of a homogeneous alloy consisting of immiscible metals. The device includes a crystallizer, fillable with a melt prepared from the metals, a homogenizer, a crystallizer, a feeder for passing a D.C. current through the melt in the crystallizer, in order to produce therein an electric field of predeterminable intensity. There is also provided an electromagnet adapted to produce therein a magnetic field of predeterminable induction, a nozzle adapted to direct jets of a coolant at selected regions of the crystallizer to cause the melt to solidify, and a puller to extract solidified portions of the alloy melt from the crystallizer. The electric field and the magnetic field are applied thereto so as to cross one another, and the interaction between the electric field produced by the D.C.
