Abstract: A tool for forming an annular workpiece, such as a gear, is provided. The tool has a cylindrical inner form member that has a perimeter that is surrounded by the gear. Driver moves axially along a central axis of the inner form member and gear. A plurality of outer form members rest on a support and are slideable with respect to the support. Each outer form member is provided with a tapered surface that corresponds with and engages with a tapered surface of the driver. Axial movement of the driver causes the tapered surfaces to engage, sliding the outer form members radially inwardly toward the gear. The outer form members are provided with surface features that form teeth onto the gear when the driver presses the outer form members against the gear.

Abstract: A water timer user interface has display areas for display of water timer status information, including watering zone and watering duration indicators, user input areas, and a touch-sensitive screen. At least one of the display areas may display a graphical representation of the watering duration indicators for the watering zone identifiers. All of the display and input areas may be single-function areas and may be simultaneously visible to and accessible by a user. The display areas may simultaneously display both graphical and numeric representations of the watering duration indicators. An ambient temperature sensor may be used to sense the ambient temperature and humidity and provide corresponding signals to the controller to permit the controller to modify the amount of water supplied.
