Title: Process for non-locally producing information, forces or energy
Inventor: HRUSHOVETZ STEPHEN M
IPC: H04B10/11
Filed: 1995-05-01
Abstract: The process for nonlocally generating information, forces or energy involves 1) producing space-quantized correlations between quanta with overlapping wave  functions, such as between magnetic moments of  fermions or between polarizations of two or more photons; 2) collecting and separately storing the correlated quanta in such a way that their  magnetic moments or polarizations can be measured in one location and manipulated at another location; 3) manipulating the magnetic moments or polarizations of one quanta at one location, which causes a measurable alteration in the magnetic moments or polarizations of corresponding correlated quanta at one or more other locations, resulting in the generation change in forces and energy at these nonlocal locations; and 4) recognizing (temporal and/or spatial) patterns in theenergy generated or change in particle mechanics at these nonlocal positions which can be interpreted as information.  One can envision systems where manipulating one object's dipole moment nonlocally affects one or more other objects' dipole moment such that the forces produced nonlocally are greater than those originally "sent", which would result in excess energy in the system as a whole.

Title: A method and apparatus for separating a substance from a liquid mixture by fractional crystallisation
Inventor: BISCHOF RUDOLF
IPC: B01D9/00
Filed: 1995-11-21
Abstract: The crystalliser (70) has an inlet (77) for the liquid medium and an outlet (84) from which the mother liquor followed by the molten crystals can be withdrawn at the end of the crystallisation process.  During the crystallisation process, a number of tubes (75) closed at the top can be supplied from above with a trickling film of liquid mixture.  The tubes are internally supplied with a trickling film of the liquid medium used for cooling.  The liquid medium is supplied via a riser (87), and a medium distributor (92) guides the flow of medium under the distribution tray (81).  The pressure of the evaporating coolant in the medium chamber (80), to which the inner chamber of the tubes also belongs, can be controlled, thus controlling the temperature of the wall of the tubes where crystallisation takes place.  In order to melt the crystals, gaseous medium can be introduced through a spigot (96) into the crystalliser under controlled pressure.  The crystalliser can serve as an evaporator or as a condenser in a refrigeration machine, in order to use both cooling energy and waste heat from the machine.
