Disclosed is a method for producing fluorinated organic compounds, including reacting CF2\u2550CFCl with CH2FCl under conditions effective to produce a product composition including CF3CClFCH2Cl. During an identification process, the devices can negotiate an operating agreement that specifies particular communications that each device is permitted to send to or receive from the other, for example by having one device send a list of specific messages that it intends to send to andor receive from the other. The device comprises a flow regulating device comprising a passage defined by at least a first element and a second element, wherein at least one of the first and second element is a primary deformable element adapted to be elastically deformed so as to change the cross sectional area of the passage. Diluting the dispersion with a wetting agent. 005-50 pockets per square centimeter.
