The invention relates to a pharmaceutical composition based on an active ingredient that is enclosed in liposomes for topical, transdermal application. Masterbatch compositions containing such salts and silica andor hydrotalcite are particularly useful in reducing haze and improving properties of manufactured polyolefin articles or film. Operation of the device includes monitoring the output from the receiver to obtain an amplitude versus time function and processing data from the function to obtain a modified signal. Additional signage areas can be formed utilizing hollow divider members having oppositely directed pairs of legs.
