           These  bar brushes  12.1  with  their  bristles  13  directed
         toward the compensating means 7 provide guidance of the
         compensating means 7 perpendicular to its direction of re-
         versal. The length of the bar brushes 12.1 is designed so that
         changes in the vertical position of reversal 7.1 of the com-
         pensating means 7 of an amount depending on the height of
         the elevator are permissible.                        Figure 5:  Exploded  elevation view, showing the  conflicting design

                                                              vention is the fact that the wall slope must be suitably

                                                              anchor. Thus, the anchor shown in figure 5 is divided into
                                                              four regions: neck region 22, transition region 52, mid re-

         guiding forces are needed and/or grinding noises should be

           This patent presents an anchor having an internal passage
         defined by a revolved wall profile. The anchor is conceptually
         divided into four regions: a neck region, a transition region,
         a mid region, and a distal region. Each of these regions has
         its  own  design  considerations.  A portion  of  a  parabola is
         used to define at least part of the revolved wall profile. The
         parabolic portion is preferably used in at least the neck and
         mid regions. In order to create a tangency condition proxi-
         mate the neck anchor boundary, the parabola used to create
         the wall profile is angularly offset from the wall profile’s axis
         of rotation.
           Figure 5 shows a conceptualized view of an ideal anchor,   Figure 6: Elevation view, showing a parabola.
