Abstract: A vertical sliding enclosure for a bathtub, including three vertically slidable glass panel assemblies, wherein each assembly contains a slidable glass panel attached by the left and right glass connectors serving as the transverse position limiters which limit the panel in the transverse movement, a pair of left and right housings having the respective longitudinal tracks for the panel in the vertical movement, and room for a counterbalancing weight system containing left and right pulleys and weight combination so that a weight of the glass panel can be balanced. The enclosure provides a sufficient height for a user to access the bathtub when the three panels are raised to their maximum heights. When in their lowered position, the three panels prevent shower water from entering the bathroom floor.

Abstract: The present invention relates to new delivery systems for cyclopropene compounds of a cyclopropene compound generator comprising at least one substrate, a material containing at least one cyclopropene compound and a release agent whereby at least one side of one substrate is coated with the material containing at least one cyclopropene compound and wherein when the material containing at least one cyclopropene compound is exposed to the release agent, a gaseous cyclopropene compound is released. The present invention also provides methods to release a cyclopropene compound from such a generator to deliver a cyclopropene compound to plants, fruits, flowers or vegetables to inhibit an ethylene response in the plants, fruits, flowers or vegetable.
