    Abstract: A system and method for inhibiting inadvertent movement of a window sash out of a fully open position. The window sash is set in guide tracks. The window sash engages brake shoes that travel up and down in the guide tracks. A stop is mounted within the guide tracks. The brake shoe and the stop have a connector that joins the brake shoe to the stop when the window sash is moved to its fully open position. The brake shoe is separable from the stop when a closing force is manually applied to the window sash. The force applied must exceed a threshold level. In this manner, the window sash will remain in its fully open position and will not inadvertently drift closed due to gravity, vibrations, or friction with another window sash.

    Abstract: A method of opening a mine door leaf installed in a mine passageway having a high pressure zone and a low pressure zone. The method includes the steps of operating a variable-throw crank mechanism in a first configuration having a first crank length to apply a first force to the mine door leaf to move at a first speed, operating the variable-throw crank mechanism in a second configuration having a second crank length less than the first crank length to apply a second force greater than the first force to the mine door leaf to move at a second speed slower than the first speed, and using a resistance pressure associated with the high and low pressure zones in the mine passageway to convert the variable-throw crank mechanism from the first configuration to the second configuration.
