Patent number: 4256576Abstract: Process is provided for the creation of crystal aggregates in one part of a tank by heat transfer from a fluid disposed in another part of the tank and maintained by heating or by cooling at a different temperature than the part containing the crystal aggregates. Both of these parts are separated from each other by a flexible membrane which is pulsated by dynamic local pressure differentials caused by foaming or by fluidizing the heat transfer fluid.Type: GrantFiled: March 29, 1974Date of Patent: March 17, 1981Assignee: Magyar Tudomanyos Akademia Muszaki _Kemiai Kutato IntezetInventors: Tibor Blickle, Zsigmond Komaromy, Judit Filka, Janos Gyenis, Oszkar Borlai

Patent number: RE34210Abstract: An ice maker in which water runs over a vertical evaporator to form ice cubes formed between vertical and horizontally mounted plates. The cubes are released from the evaporator by simultaneously applying a horizontal force to the plates while heating the evaporator.Type: GrantFiled: May 3, 1989Date of Patent: April 6, 1993Inventors: Robert C. Lane, Joseph M. Lee
