Abstract: A method for local heating includes placing first magnetic material in a first lumen, and a second magnetic material in a second lumen from the first magnetic material to a magnetically permeable rod, then applying alternating magnetic fields. The first lumen may be a fallopian tube. A method of occluding fallopian tubes uses a catheter to inject first magnetic material into the tubes, injecting second magnetic fluid into uterus, introducing a magnetically-permeable rod into vagina, positioning a second end of the rod over the fallopian tube and applying an alternating magnetic field to the first magnetic material to heat it. The method is performed with apparatus having a coil wound over a magnetically-permeable rod, a high frequency AC generator coupled to the coil, a first magnetic fluid capable of generating heat in an alternating magnetic field, and a second magnetically-permeable magnetic fluid capable of conducting magnetic fields through a lumen.

Abstract: The present invention provides a reactor and gasification process for the continuous controlled production of hydrogen (H2) and a by-product synthesis gas (mixture of CO+H2+CO2), such a process called a hydrogen priority poly-generation process (HPPP). The reactor uses a circulating molten iron process, which is capable of gasifying a variety of carbonaceous materials including low rank coals and biomass. The process employs an iron steam oxidation-reduction cycle in a multi-chamber reactor including a multi-vessel reactor system, where in one compartment or vessel hydrogen is produced by steam oxidation of molten iron; and in a second compartment or vessel the iron is regenerated by carbon reduction of molten iron oxide thereby producing a by-product synthesis gas (CO+H2+CO2), and excess heat which can be used to produce steam, and in a third step the iron is purified before being returned to the steam oxidation step in the process.

Abstract: A method of identifying a device based on GPS coordinates is provided. In one embodiment a device is identified by determining earth coordinates for the device. Once the earth coordinates are determined a unique device identifier is created based at least in part on the earth coordinates of the device. After the unique device identifier has been created, the unique device identifier is communicated to at least one other device.

Abstract: The present invention provides a process whereby pre-enrichment of water streams using a hydrogen source and a catalytic isotope exchange method at one or more remote sites to supply water with augmented deuterium concentration to a central heavy water. This central heavy water plant could be a Combined Electrolysis and Catalytic Exchange (“CECE”) heavy water production plant or a Girdler Sulfide heavy water plant. The deuterium content of water at the remote sites is increased and provides water stream(s) with augmented deuterium concentration to feed to the central heavy water production plant. This could be a first stage of the central CECE deuterium enrichment plant, increasing its capacity for heavy water production approximately in the ratio of its enrichment above natural deuterium concentrations. By relatively simple utilization of available deuterium enrichment capacity at the remote sites, advantages are achieved from a larger scale of heavy water production at the central production plant.
