  • Patent number: 6412281
    Abstract: An energy generating system includes a conduit in the form of a loop with an upflow section and a downflow section. A working liquid such as water is received within the conduit and has an ambient temperature and a boiling point. A supply subsystem including a vessel in communication with an input port at a lower portion of the upflow section of the conduit is configured to provide to the conduit a pumping liquid. The pumping liquid has a boiling point greater than the ambient temperature and less than the boiling point of the working liquid. A heating subsystem is configured to heat the working liquid within the conduit to a temperature greater than the boiling point of the pumping liquid by a predetermined differential. Accordingly, the pumping liquid is vaporized after passing through the input port into the working fluid, thereby generating pumping gas.

  • Patent number: 5078117
    Abstract: A projectile propellant device is adapted to supply a compressed gas from a compressed gas container for providing the propulsion force for a projectile or for providing the operating force for a gas powered device. The propellant device includes a gas container containing a volume of gas at sufficient pressure for applying a desired force upon release, and a compressed gas releasing structure for producing a release opening in the compressed gas container in response to the detonation of a pyrotechnic material. The release opening releases the compressed gas for applying the desired force, such as a propulsion force to propel a projectile. The gas releasing structure preferably includes a pyrotechnic charge device and a puncturing device both mounted within a suitable device housing along with the gas container.

  • Patent number: 4759191
    Abstract: Disclosed is a self-contained, rapid cooling device that retains heat produced from the cooling process and can be stored for indefinite periods without loosing its cooling potential. A liquid in a first chamber undergoes a change of phase into vapor, which cools the first chamber. A sorbent in a second chamber is in fluid communication with the vapor and removes the vapor from the first chamber. The cooling process is facilitated by lining the interior surface of the first chamber with a wicking material to retain the largest possible contact between the liquid and the first chamber as the level of the liquid lowers during the vaporization process. A phase separator prevents unvaporized liquid from passing into the second chamber. The device is self-contained because a material in contact with the sorbent removes the heat from the sorbent to prevent the reduction in the cooling effect produced by the first chamber.

  • Patent number: 4571534
    Abstract: A system is disclosed for converting one form of energy into an alternate form of energy by means of a low-temperature process. A liquid flow loop with two vertical columns that are interconnected at the top and bottom circulates a fluid. A convective flow of this fluid is established by heating the fluid in one of the columns and cooling the fluid in the other column to establish a weight differential between the fluid in the two columns. An electric generator is placed on this loop so that, as the fluid flows through the loop and through the generator, electrical energy is generated. This electrical energy is used to electrolize a second fluid, such as a solution of sulphuric acid, into gasses such as hydrogen and oxygen. The gasses so generated are used to increase the rate of flow of the fluid, and consequently the rate of electric energy production. The preferred embodiments incorporate a fermentation process to produce Carbon dioxide gas and heat energy.

  • Patent number: 4486701
    Abstract: A system is disclosed for converting thermal energy into chemical energy by means of a low-temperature process. A liquid flow loop with two vertical columns that are interconnected at the top and bottom circulates an electrically conducting fluid, such as mercury. A convective flow of this electrically conducting fluid is established by heating the fluid in one of the columns and cooling the fluid in the other column to establish a weight differential between the fluid in the two columns. A magnetohydroynamic generator is placed on this loop so that, as the fluid flows through the loop and through the generator, electrical energy is generated. This electrical energy is used to electrolize a second fluid, such as a solution of sulphuric acid, into gasses such as hydrogen and oxygen. The gasses so generated are injected into the rising column of the electrically conducting fluid to increase the weight differential between the fluid in the two columns and enhance the convective flow of that fluid.

  • Patent number: 4253132
    Abstract: A weapon for subduing and restraining includes an electrical power supply. The magnitude and frequency of the electrical impulses delivered to the target provide energy in excess of 0.001 joules and ranges in effect from immobilizing to potentially "lethal" levels.

  • Patent number: 3969731
    Abstract: A mesh article, such as a reflector for radio frequencies, comprises glassy base fibers of high tensile strength, low elongation properties and low coefficient of expansion, the fibers being coated with a thin layer of metal. In a typical embodiment, the fibers are quartz coated with aluminum. The fibers are not interwoven and are bonded together at their intersections and to a peripheral ring support. These articles are lightweight, flexible and foldable and possess a "shape memory.
