Abstract: 1. A process for separating a gaseous mixture comprising isotope compounds, in particular 235 UF6 and 238 UF6 , by selective excitation of an isotope compound of the mixture by means of laser radiation, in particular pulsed laser radiation, of a specific frequency to produce a photo-activated chemical reaction of the one isotope compound with a reaction partner or a photo-dissociation of the isotope compound to be excited on the basis of the multi-photon process and with subsequent chemical and/or physical separation of the excited compound from the non-excited isotope compounds, wherein the gaseous mixture of the isotope compounds is expanded adiabatically into an evacuated radiation zone through at least one expansion nozzle and is thereby cooled to below 100 K, and wherein as a result of the selective excitation the product stream enriched with the desired isotope contains molecular compounds of the general formula UFn (n =< 5), which condense in the product stream, combine to form solid particles and are deposited on separating surfaces arranged after the radiation zone, characterised in that - the product stream is directed through an electrostatic electrode grid system (ER) in the individual grid elements of which, between a point electrode (6.1) and an annular electrode (5.1) spaced from and surrounding it, respective inhomogeneous local electric fields (er ) having a field gradient running transverse to the direction of flow are produced, - through the electrode grid system (ER) molecular dipoles are induced on the solid particles flowing through and the molecular dipoles are accelerated in the direction of the field gradients and are separated on the point electrodes (6.1) in the form of a solid deposit.

Abstract: A combination convergent jet engine aircraft nozzle (86, 142 146) and a ventilation tube (88, 136, 144) are fixed in place and have no moving parts. Ambient air is entrained through duct inlets (96, 140, 154, 160), through the nozzle walls, through hollow struts (90, 138), the struts supporting and being connected to a hollow central tube (102, 144) or a plurality of tubes (136), to adjacent the downstream end of the nozzle to mix at takeoff with the jet forming gas exhaust. The ducts (102, 136, 144) are positioned with respect to the nozzle exhaust so that entrained ambient air flows into the gas exhaust during takeoff and so that the ambient air flow is substantially restricted or shut off during cruise flight. Ambient air inlet openings (160) are formed as a porous surface, the holes through the surface being generally in the shape of louvers (166) of which downstream end portions (174) are depressed inwardly of the outer wall surface of the nozzle to provide a minimum drag along the outer nozzle periphery during cruise flight and at takeoff. 
     A method of positioning and fixing the outlet end of a noise suppressor within a convergent nozzle so that entrained ambient air flows into the gas exhaust during takeoff to substantially reduce the engine noise and so that ambient air is substantially restricted or is shut off entirely during cruise flight. 
     The method in which ambient air is entrained in a noise suppressor within a convergent nozzle and is exited downstream adjacent the nozzle downstream end to mix with the gas exhaust during takeoff to suppress the engine noise, and at cruise flight substantially restricting or shutting off the ambient air through the noise suppressor by turning engine exhaust gas toward the noise suppressor axis downstream of the ambient air exit.
