  • Patent number: 4267022
    Abstract: Method and apparatus for desalinizing water. Salt water in an evaporation zone is provided with heat of vaporization by a heat pump which transfers heat to the water from a thermal sink. The evaporation zone is maintained at subatmospheric pressure so that the salt water boils at a temperature at least about 10 degrees above the ambient dew point. The pressure in the evaporation zone is maintained at a low level by a vacuum pump and by condensing the vapor in a condensation zone from which fresh water is collected. The heat of condensation is dissipated into a "cold" sink if available or by a heat dissipating means such as an evaporative cooling apparatus. Energy efficiency results from the ability of the heat pump or pumps in the system to operate at a high coefficient of performance.

    Abstract: Thermal energy, especially solar heat, is converted into chemical energy by being used for the endothermic dissociation of a compound which is exothermically recombinable to release at least a substantial part of that energy at a time and/or location at which the original heat source is not readily available. One or more of the dissociation products are transported to the point of utilization, preferably after interim storage, and are there recombined with one another and/or with locally available reactants to restore the original compound which is then returned, again preferably after interim storage, to the dissociation site for a repetition of the process. The exothermic reaction at the recombination site may be used to decompose a locally available compound, e.g. water, for the purpose of liberating one of its constituents, e.g. hydrogen.

  • Patent number: 4169499
    Abstract: A method of low temperature energy storage and utilization is disclosed which can be used in conjunction with low temperature heat sources such as solar energy flat plate collectors. Input heat energy is utilized to sustain the endothermic dissociation of ammonium carbamate produced from a reaction between urea and water. The energy is retained in the form of the higher energy containing dissociation products ammonia and carbon dioxide. The dissociation products are separated by liquifying and draining off the ammonia and are held under pressure. The stored heat is extracted in the form of output heat energy for an end use by reversing the dissociation reaction and combining the ammonia and carbon dioxide to form ammonium carbamate which becomes urea and water and is recirculated as a slurry. Closed-loop, fluid-medium heat exchange systems can be used both in the input and output sides of the energy system. The entire system operates at temperatures of less than 250.degree. C.

The forward and reverse chemical reactions are slow enough to prevent substantial reaction during the separation and transfer of the chemicals, but they may be speeded by catalysts within the reaction chambers.

    Abstract: A fixed, linear, ground-based primary reflector having an extended curved-sawtooth contoured surface covered with a metallized polymeric reflecting material, reflects solar energy to a movably supported collector that is kept at the concentrated line focus of the reflector primary. The primary reflector may be constructed by a process utilizing well-known freeway paving machinery. The solar energy absorber is preferably a fluid-transporting pipe. Efficient utilization leading to high temperatures from the reflected solar energy is obtained by cylindrical shaped secondary reflectors that direct off-angle energy to the absorber pipe. To obtain higher temperature levels, refocusing secondary reflectors, that cause a series of discrete spots of highly concentrated solar energy to fall on the fluid-transporting pipe, are utilized. A seriatim arrangement of cylindrical secondary reflector stages and spot-forming reflector stages produces a high temperature solar energy collection system of greater efficiency.

    Abstract: A foodstuff container capable of heating or cooling food or beverage contained therein having three compartments to accommodate food or beverage, an exothermal or endothermal reaction agent, and a reaction-inducing agent respectively, a needle member to open a way for the thermal reaction agent and the reaction-inducing agent to mix with so as to cause a thermal reaction for heating or cooling the contained food or beverage, and a bottom cover having at its center a plurality of pleats radiating therefrom, said pleats affording some elasticity and flexibility to said bottom cover, said bottom cover also projecting outward at its center so that said bottom cover can bounce back inwardly at the center upon pushing by a finger from the outside so that the bottom cover pushes the needle existing between the compartments accommodating the exothermal or endothermal reaction agent and the reaction-inducing agent respectively, so that the two agents mix to produce thermal reaction as the result.

  • Patent number: 3967676
    Abstract: At a heat source, such as a nuclear reactor, phosgene is reacted to form a mixture of carbon monoxide and chlorine. This mixture of gases is cooled by heat exchange with incoming cold phosgene and is pumped through a first pipeline at ambient temperature to an energy use area. At the energy use end of the first pipeline the gas mixture is heated in the presence of a catalyst, such as activated charcoal. The CO and Cl.sub.2 react exothermically to form COCl.sub.2 (phosgene) with the liberation of 26 keal per mol of phosgene formed. The heat evolved from this reaction is released across a heat exchanger for the boiling of water and superheating of the resultant steam to a temperature in the 400.degree.-500.degree.C range for use as process heat or the generation of electricity. The phosgene produced is cooled and then returned to the heat source end via a second pipeline for repetition of the closed loop process described.

  • Patent number: 3958625
    Abstract: At a heat source, such as a nuclear reactor, methane and carbon dioxide are reacted (at about 800.degree.-900.degree.C) to form a mixture of carbon monoxide and hydrogen. This mixture of gases is cooled by heat exchange with incoming cold CH.sub.4 and CO.sub.2 and is then pumped through a first pipeline at ambient temperature to an energy use area. At the energy use end of the first pipeline the gas mixture is heated (to about 350.degree.-500.degree.C) in the presence of steam and a catalyst. The CO and H.sub.2 react exothermically to form CH.sub.4 and CO.sub.2. The heat evolved from this reaction is released across a heat exchanger for use as process heat or for conversion to electricity. Water is condensed and separated from the mixture of gaseous reactants and the dried, cooled CH.sub.4 /CO.sub.2 mixture is returned to the heat source end via a second pipeline for repetition of the closed loop process described.

  • Patent number: 3957472
    Abstract: A portable heat transfer unit in the form of a chemical package includes at least two chemical heat transfer materials separated by a chemical buffer material. In their dry state and in their separated condition the chemical heat transfer materials will remain inactive. The introduction of an activating fluid will cause the respective materials to individually and jointly react and interact to produce an extended heat transfer effect.

  • Patent number: 3950158
    Abstract: In a thermal pack, one which may be provided with ingredients for making it either a cold pack or a hot pack, three bags are provided for the container of the pack, two of said bags being of the same size and comprising the exterior and proximate interior liners of the pack, while another bag of lesser dimensions forms the inner liner of said pack, and is disposed within the two larger bags. The inner bag is designed for holding a quantity of water, while the interior liner of the two outer bags is provided for holding a quantity of chemical means for use in varying the temmperature of the desired type pack. Rupturing of the inner bag through manual pressure allows water to react with the chemical means for creating either the cold or hot temperature, as needed.
