  • Patent number: 9577461
    Abstract: Charging a first device by a second device. The first device determines a first position of the first device relative to the second device. Based on the charging position, automatically moving, by the first device, into a second position on the second device. The first device comprises a first motor and a second motor. The first motor is capable of moving the first device along a first axis. The second motor is capable of moving the first device along a second axis.
    Type: Grant

  • Publication number: 20150301602
    Abstract: A device receives a notification. The notification comprises a first response or a second response. Based on the notification being a first response, the device vibrates along a first direction. Based on the notification being a second response, the device vibrates along a second direction. The device comprises a first motor and a second motor. The first motor is capable of vibrating the device along a first axis. The second motor is capable of moving the device along a second axis.

  • Patent number: 7427386
    Abstract: The invention provides a series of techniques for processing uranium containing feed materials such as uranium ores, reprocessed uranium, uranium containing residues and uranium containing spent fuel. The processes described involve fluorination of uranium containing material, separation of the uranium containing material from other materials based on ionization thereof with the non-ionized fluorine containing material being recycled. Metallic uranium and/or plutonium and/or fission products may result. The technique offers advantages in terms of the range of materials which can be reprocessed and a reduction in the number of complexity of stages which are involved in the process.

  • Patent number: 6267850
    Abstract: Improved processing apparatus and methods are provided which involve the selective ionisation of a feed material and the separation of ionised and non-ionised species. Introduction of a chemical material to cause selective transition to a non-ionised and/or solid or liquid state of part of the feed is provided. The process offers high through puts by virtue of the ionised and non-ionised species being in equilibrium with one another.

  • Patent number: 5322545
    Abstract: Uranium chloride is reacted with either magnesium, sodium or calcium in the presence of a molten salt comprising light metal chlorides including lithium chloride. The temperature is maintained below the melting point of uranium. The magnesium may be in the form of magnesium-cadmium alloy, the temperature being maintained below the temperature at which magnesium and cadmium vaporize. The components of the molten salt may be first fused together so as to form the molten salt eutectic. Subsequently after separation of the uranium, products of the reaction may be recovered and recycled.

  • Patent number: 5017345
    Abstract: In a method of producing uranium (IV) fluoride, a feedstock comprising uranium metal or alloy is dissolved in hydrochloric acid and hydrofluoric acid to produce a clear solution. The solution is heated and excess hydrofluoric acid added to produce a precipitate comprising uranium (IV) fluoride.
