Bromine And Fluorine As Only Halogens Patents (Class 514/761)
  • Patent number: 9476622
    Abstract: A part replacement method replaces a part of a refrigeration cycle apparatus including a compressor, a heat source side heat exchanger, an expansion device, a heat exchanger related to heat medium, and first and second refrigerant flow closing devices. The first and second refrigerant flow closing devices control a flow of a refrigerant into and out of an outdoor unit accommodating the compressor and the heat source side heat exchanger. The method includes a pump-down step of closing the first refrigerant flow closing device, allowing the refrigerant in a pressure reduction section to flow into the outdoor unit and reducing a pressure in the reduction section until a set pressure or time is reached, a flow closing step of closing the second refrigerant flow closing device, and a part replacement step of removing the part from the refrigerant circuit by heating to replace the part.

  • Patent number: 7820594
    Abstract: This invention relates to agricultural compositions, particularly pesticidal compositions which find particular use as a fungicide or herbicide composition. The pesticidal composition can include one or more fatty acids and one or more organic acids different from the fatty acid. The organic acid can but need not exhibit any fungicidal activity; however, when combined with a fatty acid, the organic acid functions as a potent synergist for the fatty acid as a fungicide. Additionally, the pesticidal composition can include other components such as emulsifiers, adjuvants, surfactants and diluents. The pesticidal composition significantly reduces or prevents the fungal infection of cash crops including vegetables, fruits, berries, seeds, grains and at higher application rates, can also be used as a herbicide and/or harvest aid or desiccant for harvested crops such as potatoes. The addition of an emulsifier further enhances the herbicidal properties of the compositions.
