Abstract: A user interface for a thermostat that controls a radiator valve can include a user input member that is movable from a home position to a set point increase or decrease position to increase or decrease a set point temperature of the thermostat. In some embodiments, a return mechanism returns the user input member to the home position after being released from one of the set point increase and decrease positions. The user interface can include an indicator panel and controller that controls the indicator panel to provide an indication of when the set point temperature of the thermostat is being adjusted. The user interface can also include a lockout controller that prevents further set point temperature adjustments using the user interface when the set point temperature differs from the environmental temperature by a specified amount.

Abstract: On-site pressing of field poles for a hydroelectric generator is provided. A field pole may be placed on a press cart and press bars may be placed on top of the field pole. The press cart is moved along a track to transport the field pole to a pressing unit. Hydraulic cylinders in the pressing unit press the field pole and the press bars between the cart and a top plate of the pressing unit to straighten the field pole.

Abstract: A method for repairing a discharge ring of a hydraulic turbine with a turbine runner in place includes: mounting adjustable fixtures to runner blades that are approximately evenly spaced around the turbine runner, where each adjustable fixture is mounted to a different runner blade at a different predetermined vertical position with respect to a surface of the discharge ring; attaching cutting equipment configured to remove material from the discharge ring to each adjustable fixture installed on the runner blades; installing a drive unit configured to rotate the turbine runner; controlling the drive unit to rotate the runner at a specified speed; and controlling the cutting equipment attached to each adjustable fixture to concurrently remove material from the discharge ring as the turbine runner rotates.
