  • Patent number: 9494512
    Abstract: Systems and methods for remotely detecting nuclear and non-nuclear materials such as chemical agents and gas-phase explosives are disclosed. Nuclear and non-nuclear materials may be detected by transmitting electromagnetic energy toward a remote target area, collecting scattered electromagnetic energy reflected from the remote target area, analyzing an absorption spectrum of the collected scattered electromagnetic energy, and detecting a presence of at least one nuclear or non-nuclear material in the remote target area based on the analyzed absorption spectrum.

  • Patent number: 9316184
    Abstract: An apparatus (100) for reducing the size of fuel particles injected into a combustion chamber is disclosed. The apparatus includes fuel line (110), a first metallic mesh (114) disposed within the fuel line (110), and a second metallic mesh (112) disposed within the fuel line (110), upstream of the first metallic mesh (114). An electrical supply (130) is electrically coupled to the first metallic mesh (114) and the second metallic mesh (112). Operation of the electrical supply (130) generates an electrical field between the first metallic mesh (114) and the second metallic mesh (112). A fuel injector (120) is disposed at an end of the fuel line (110), downstream from the first metallic mesh (114). Methods of reducing the size of fuel particles, improving gas mileage in a vehicle, increasing power output from a combustion engine, and improving emissions for a combustion engine are also provided.

  • Patent number: 9198446
    Abstract: The present invention relates to a method and an apparatus for producing a chocolate product. The method includes delivering liquid chocolate having a viscosity through a pipe along a delivery path to a production station for producing the chocolate product. The liquid chocolate includes solid particles suspended within the liquid chocolate. The method changes the viscosity of the liquid chocolate by applying an electric field to the liquid chocolate in a direction along the delivery path of a strength and duration determined to aggregate the suspended solid particles into streamlined shapes extending along the direction of the delivery path.

  • Patent number: 8826997
    Abstract: A fire sprinkler including a generally tubular body having inlet and outlet ends is disclosed. The body defines a fluid flow passage extending between the inlet and the outlet such that the outlet is in fluid flow communication with the inlet. A magnetized member is disposed within the fluid flow passage and is movable between a first position wherein fluid flow communication between the outlet and the inlet is blocked and a second position wherein fluid flow communication between the outlet and the inlet is open. A temperature sensitive magnetic member is coupled to the body and has sufficient magnetic properties to attract the magnetized member below a predetermined temperature, thereby maintaining the magnetized member in the first position. The temperature sensitive magnetic member loses a sufficient percentage of its magnetic properties at and above the predetermined temperature, thereby allowing the magnetized member to move to the second position.
