Abstract: A method and apparatus for preparing aromatic hydrazo compounds by electrochemical reduction of aromatic nitro compounds on a technical scale. The reaction is carried out continuously and in two steps, comprising a first step in which the aromatic nitro compounds are reduced to form the corresponding azoxy compounds, which are isolated, and a second step in which the azoxy compounds isolated are reduced to form the corresponding hydrazo compounds.

Abstract: Safety ski bindings include a boot retaining clip for engaging a ski boot at the heel and/or toe thereof. A toggle linkage system is operably connected to the boot retaining clip and is movable between a locked position for forcing the retaining clip against the boot to retain the boot on the ski, and an unlocked position for disengaging the retaining clip from the boot to permit the ski boot to separate from the ski. An actuated member is movable to unlock the linkage system to permit the linkage system to move into its unlocked position for releasing the retaining clip from the ski boot when the ski binding is displaced a certain distance relative to the ski in either one or both of two directions which are perpendicular to each other. Preloaded biasing means resist the displacement of the ski binding relative to the ski in one of the two directions, and a different preloaded biasing means resists the displacement of the binding relative to the ski in the other direction.
