Abstract: An impulse turbine comprises at least one runner keyed to a drive shaft in association with a distributor unit which has, for each runner, a circular outlet for the supply of fluid from the distributor unit to the blades of a respective runner. Each outlet is arranged coaxially inside the respective runner and the distributor unit is shaped in a manner such as to define a substantially circular path for the fluid and to cause the fluid to emerge from the distributor unit through the at least one outlet predominantly tangentially relative to the outlet.

Abstract: A thermographic device has a elongated handle, provided with a small fan (3), and a frame (6) and an image acquisition camera (9) provided at the respective ends of the handle. The frame is provided with a quick coupling (7) for a thermographic plate and the fan is suitable to blow air onto the surface of the organ to be examined before resting the thermographic plate.
