Abstract

A method is provided for measuring the heat influx of a cryogenic transfer system. A gaseous phase of the cryogen used during normal operation of the system is passed through the system. The gaseous cryogen at the inlet to the system is tempered to duplicate the normal operating temperature of the system inlet. The temperature and mass flow rate of the gaseous cryogen is measured at the outlet of the system, and the heat capacity of the cryogen is determined. The heat influx of the system is then determined from known thermodynamic relationships.

System and method for charging electrochemical cells in series. [Patent application]

Patent DeLuca, W H; Hornstra, F Jr; Gelb, G H; ...

A battery charging system capable of equalizing the charge given each individual cell at a selected full charge voltage includes means for regulating charger current to increase current at a constant rate until a bulk charging level is achieved or until any cell reaches a safe reference voltage. A system controller then begins to decrease the charging rate as long as any cell exceeds the reference voltage until an equalization current level is reached. At this point, the system controller activates a plurality of shunt modules to permit shunting of current around any cell having a voltage exceeding the referencemore »« less
Method of uranium reclamation from aqueous systems by reactive ion exchange. [US DOE patent application; anion exchange resin of copolymerized divinyl-benzene and styrene having quarternary ammonium groups and bicarbonate ligands]

Patent Maya, L

A reactive ion exchange method for separation and recovery of values of uranium, neptunium, plutonium, or americium from substantially neutral aqueous systems of said metals comprises contacting said system with an effective amount of a basic anion exchange resin of copolymerized divinyl-benzene and styrene having quarternary ammonium groups and bicarbonate ligands to achieve nearly 100% sorption of said actinyl ion onto said resin and an aqueous system practically free of said actinyl ions. The method is operational over an extensive range of concentrations from about 10/sup -6/ M to 1.0 M actinyl ion and a pH range of about 4more »« less
Method for fabricating cermets of alumina-chromium systems. [Patent application]

Patent Morgan, C S

Cermet insulators resistant to thermal and mechanical shock are prepared from alumina-chromium systems in the following way: by providing an Al/sub 2/O/sub 3/ material of about 0.5 to 7.0 micron size with a solid-hydrocarbon overcoating by slurrying an effective amount of said solid hydrocarbon in a solvent mixture containing said Al/sub 2/O/sub 3/ and thereafter evaporating said solvent, contacting said coated Al/sub 2/O/sub 3/ with a solution of chromium precursor compound, heating the resulting mixture in a reducing environment to a temperature above the decomposition temperature of said chromium precursor compound but less than the melting temperature of the Al/submore »« less
Quantitative method for measuring heat flux emitted from a cryogenic object

Patent Duncan, R V

The present invention is a quantitative method for measuring the total heat flux, and of deriving the total power dissipation, of a heat-fluxing object which includes the steps of placing an electrical noise-emitting heat-fluxing object in a liquid helium bath and measuring the superfluid transition temperature of the bath. The temperature of the liquid helium bath is thereafter reduced until some measurable parameter, such as the electrical noise, exhibited by the heat-fluxing object or a temperature-dependent resistive thin film in intimate contact with the heat-fluxing object, becomes greatly reduced. The temperature of the liquid helum bath is measured at thismore »« less
