Patent number: 7021900Abstract: A kinetic pump and method of pumping a liquid comprising providing an acceleration tube for the acceleration of a liquid contained therein by an introduced high-pressure vapor or gas, receiving the liquid from the acceleration tube with a compressed-air surge tank, admitting the liquid from the acceleration tube into the compressed-air surge tank via a check valve, draining the liquid from the compressed-air surge tank from an outlet, and adding additional liquid to the acceleration tube via an inlet, wherein during each first half cycle of the method, the vapor or gas forces the liquid to accelerate in the acceleration tube, whereby a portion of the liquid is forced into the compressed-air surge tank, and wherein during each second half cycle of the pump, the vapor or gas is substantially removed from the acceleration tube and the liquid flows back to its original location and the additional liquid is added to the liquid.Type: GrantFiled: September 20, 2004Date of Patent: April 4, 2006Inventors: Melvin L. Prueitt, Reed J. Jensen, Ernst C. Janzen

Patent number: 6066187Abstract: The red shift of the absorption spectrum of CO.sub.2 with increasing temperature permits the use of sunlight to photolyze CO.sub.2 to CO. The process of the present invention includes: preheating CO.sub.2 to near 1800 K; exposing the preheated CO.sub.2 to sunlight, whereby CO, O.sub.2 and O are produced; and cooling the hot product mix by rapid admixture with room temperature CO.sub.2. The excess thermal energy may be used to produce electricity and to heat additional CO.sub.2 for subsequent process steps. The product CO may be used to generate H.sub.2 by the shift reaction or to synthesize methanol.Type: GrantFiled: March 4, 1998Date of Patent: May 23, 2000Assignee: Reed J. JensenInventors: Reed J. Jensen, John L. Lyman, Joe D. King, Robert D. Guettler

Patent number: 4734177Abstract: A process and apparatus for separating isotopes by selective excitation of isotopic species of a volatile compound by tuned laser light. A highly cooled gas of the volatile compound is produced in which the isotopic shift is sharpened and defined. Before substantial condensation occurs, the cooled gas is irradiated with laser light precisely tuned to a desired wavelength to selectively excite a particular isotopic species in the cooled gas. The laser light may impart sufficient energy to the excited species to cause it to undergo photolysis, photochemical reaction or even to photoionize. Alternatively, a two-photon irradiation may be applied to the cooled gas to induce photolysis, photochemical reaction or photoionization. The process is particularly applicable to the separation of isotopes of uranium.Type: GrantFiled: November 26, 1975Date of Patent: March 29, 1988Assignee: The United States of America as represented by the United States Department of EnergyInventors: C. Paul Robinson, Reed J. Jensen, Theodore P. Cotter, Keith Boyer, Norman R. Greiner

Patent number: 4655890Abstract: Multiple photon absorption from an intense beam of infrared laser light may be used to induce selective chemical reactions in molecular species which result in isotope separation or enrichment. The molecular species must have a sufficient density of vibrational states in its vibrational manifold that, is the presence of sufficiently intense infrared laser light tuned to selectively excite only those molecules containing a particular isotope, multiple photon absorption can occur. By this technique, for example, intense CO.sub.2 laser light may be used to highly enrich .sup.34 S in natural SF.sub.6 and .sup.11 B in natural BCl.sub.3.Type: GrantFiled: February 8, 1985Date of Patent: April 7, 1987Assignee: The United States of America as represented by the United States Department of EnergyInventors: C.

Patent number: 4447303Abstract: A method of boron isotope enrichment involving the isotope preferential photolysis of (2-chloroethenyl)dichloroborane as the feed material. The photolysis can readily be achieved with CO.sub.2 laser radiation and using fluences significantly below those required to dissociate BCl.sub.3.Type: GrantFiled: January 23, 1981Date of Patent: May 8, 1984Assignee: The United States of America as represented by the United States Department of EnergyInventors: Reed J.
