Abstract: A curtain track for an aircraft cabin enables curtain sliders to be quickly loaded into the curtain track. The curtain track is constructed of an elongate channel with a first end fitting on a first end of the channel and a second end fitting on a second end of the channel. There is a unique cutout in the bottom surface of the first end fitting that forms a curved slot surface that enables curtain sliders to be loaded into the channel of the curtain track through the cutout to quickly load the curtain onto the curtain track without disassembling any of the parts of the curtain track or removing the curtain track from its attachment to the aircraft cabin.

Abstract: A family of propylene amine oxime ligands has the formula 2 ##STR1## wherein preferably R.sup.1 is Cl-C4 alkyl or phenyl and each of R, R.sup.2, R.sup.3 and R.sup.4 is H or Cl-C4 alkyl. The technetium-99m complexes of these ligands are lipophilic neutral complexes useful as diagnostic radiopharmaceuticals and particularly for brain scanning. The ligands show stereoisomerism. The preparation and properties of the dl- and meso-stereoisomers, and of the d- and l-enantiomers, are described. The l-enantiomer and the dl-stereoisomer of the preferred compound (2, R=R.sup.1 =R.sup.2 =CH.sub.3, R.sup.3 =R.sup.4 =H) show good retention in the brain.
