Abstract: A system for installing and extracting a flowing water turbine below the surface of the water includes a flow inducer assembly for improving the conversation of the kinetic energy of a waterway to mechanical energy. The flow inducer assembly includes a nozzle that may be shaped as a cowling and a outlet diffuser. The system may be useful in a number of settings, including, but not limited to, streams, rivers, dams, ocean currents, or tidal areas that have continuous or semi-continuous water flow rates and windy environments.

Abstract: A welded metal product includes a first metal plate having a first surface and a second surface opposed to the first surface; and a second metal plate being cold-pressure welded with the second surface of the first metal plate by directly pressing the first metal plate with the die. The first surface has a recess portion which is deformed by directly pressing with a die. A hardness of the first metal plate is greater than a hardness of the second metal plate.

Abstract: A rotating table apparatus using a cam mechanism and having a higher precision than a conventional rotating table is realized. A rotating table apparatus having a driven shaft supported by a housing and driven by a driving device, and a rotating table which is rotatingly driven by said driven shaft using a cam and cam followers, wherein the rotating table apparatus has an opposing surface which opposes an end surface of the rotating table in a direction along a rotation shaft of said rotating table, and oil is intervened in between the opposing surface and said end surface.

Abstract: A orientation device including two turrets, carrying a plurality of punch-die pairs, are rotatable to carry a punch-die pair to a work station and, simultaneously, another punch-die pair to a changeover station. A magazine of punch-die pairs comprises at least one pair of discs joined to each other and carrying a series of punch-die pairs. The discs are selectively rotated to take a predetermined new punch-die pair to a collection station. At least one exchange arm is rotated by a corresponding servomotor and carries at least one gripper element, axially and radially moveable with respect to the arm, independently of each other.

Abstract: A tool turret for machine tools has a turret housing and a turret head rotatably mounted in the turret housing about a rotary axis and lockable in selected angular settings relative to the turret housing. A carriage supports the turret housing and guides movement of the turret housing relative to a machine tool support in a Y direction transverse to the rotary axis. A carriage guide is on the tool support for guiding movement of the carriage. A carrier plate is part of the carriage, and extends in a plane defined by the Y direction and an X direction or a Z direction.

Abstract: A machine has an intermittently rotating table for holding parts to be worked on or assembled. Operating units (20, 21, 25) are actuable either simultaneously for all units or groups of units, or independently of one another. The operating units can be mounted vertically over or under the table and also laterally and can receive the rotary movement of a central wheel or independent motors. According to a preferred embodiment, the control of the feed is effected by the central shaft (4). During a work cycle, this shaft makes a vertical movement and transmits that movement to the operating units (20, 21) by radial linear cams (16, 17, etc.), i.e., feed and return occur during a single movement of the shaft (4), for example, downward. During idle time, i.e.
