Patent DE-1931912-A1 (DE)
Title: Nuclear energy from water
Inventor: BAUER GREGOR
IPC: G21C1/00
Filed: 1969-06-24
Abstract: Water droplets are injected into a zone where they are heated instantaneously to 2500 degrees C. by induction coils so that flash steam is formed. The temperature rise is so rapid that molecular combustion of the individual hydrogen and oxygen atoms takes place with the resultant formation of high energy particles from the water molecules and the free excess oxygen. These particles can not escape but are driven explosively into the atomic cores thus liberating further energy.

Title: Ice cream mixing-freezing machine - has automatically adjusted overflow pipe between ice cream mix container and freezer
Inventor: POVIGNA TARCISIO
IPC: A23G9/20
Filed: 1973-08-13
Abstract: An ice cream machine consists of an ice mixing container linked to a continuously working freezer.
