The gate pivot is formed by a rotatably mounted tubular beam on which the frame is mounted by means of bearing members which are provided on the frame and engage peripheral surface portions of the tubular beam spaced apart at a sufficient angle, and which members are locked in such engagement by bolts that are secured to the frame and extend therefrom and into securement with the tubular beam along lines located between radial lines through such surface portions. A tank for the sector float of the gate is supported at one end by the walls of the water course and at its other end by rollers engaging the peripheral surface of the tubular beam.

The invention relates to the wedging of coils on the rotors with salient poles of electric machines with wedges put between the coils. The wedges are kept in place through studs which connect them through ball-and-socket joints to attachment pieces resting under two adjacent coils. Such a wedging is especially useful in long machines wherein the rotor is subjected to extensive heating.

The control gate herein embodies a sector float immersed in a container which is in communication with the tailrace through an opening formed between the lower end of the downstream wall of the container and its base which projects downstream beyond such opening to shelter the latter from the tailrace current.

In the monorail installation disclosed herein the vehicle suspended from the rail is driven by a swivel roller provided on an overhead truck and means comprising a controlled surface moving in a closed path and affording a lower generatrix parallel to the direction of the travel of the vehicle on the rail and against which bears the upper generatrix of the swivel roller. The controlled surface has imparted to it a continuous movement in a direction transverse with respect to the direction of the rail, and the center of gravity of the vehicle and the swivel roller are located laterally on opposite sides of the rail so that the swivel roller will automatically bear against the controlled surface with a given pressure.

THE IMPROVED VALVE HEREIN IS COMPOSED OF A VALVE MEMBER HAVING A FLOAT WHICH IS LOCATED ADJACENTLY ABOVE A HORIZONTAL ITS OPEN POSITION IS LOCATED ADJACENTLY ABOVE A HORIZONTAL DISCHARGE OPENING FOR THE LIQUID, THE BUOYANCY OF THE FLOAT EXERTING AN UPWARD FORCE ON THE VALVE MEMBER AND THE LIQUID DISCHARGING THROUGH THE OPENING EXERTING A DOWNWARD FORCE ON THE VALVE MEMBER. THE VALVE MEMBER ALSO COMPRISES A TUBE WHICH EXTENDS UP THROUGH THE BODY OF THE LIQUID AND BALLAST FOR BALANCING THE SURPLUS UPWARD FORCE THEREON TO PLACE THE VALVE MEMBER UNDER AN EQUILIBRIUM WHICH WILL ENABLE IT TO CLOSE AT A GIVEN FLOW VALUE. ASSOCIATED WITH THE VALVE MEMBER ARE MEANS FOR COMPENSATING FOR VARIATIONS IN ITS BUOYANCY DUE TO VARIATIONS IN THE LEVEL OF THE BODY OF LIQUID IN WHICH IT IS LOCATED. THESE COMPENSATING MEANS COMPRISE A COUNTERWEIGHT IMMERSED IN THE BODY OF LIQUID WITH THE FLOAT AND CONNECTED TO MEANS FOR APPLYING TO THE TUBE FORCES WHICH ARE EQUAL TO BUT OPPOSITE IN DIRECTION TO THE TUBE FORCES FORCES APPLIED TO THE TUBE AT THE DIFFERENT LEVELS OF THE LIQUID THROUGH WHICH IT EXTENDS.
