Abstract: A system for performing industrial operations comprises at least one tool head provided with a tool and at least one sensor associated to the tool head. The system further comprises a control module mounted on the tool head including a data-acquisition unit connected to the sensor configured for acquiring the data coming from said at least one sensor, and a wireless transmission unit connected to the acquisition unit for receiving the aforesaid acquired data and for transmitting the data acquired to a receiving unit in a wireless mode. The module further comprises a device for storing electrical energy for electrical supply of the control module. The system further comprises a wireless charging system for charging the device for storing electrical energy comprising a first charging device carried by the tool head and connected to the energy-storage device and a second charging device associated to a stationary workstation.

Abstract: A fluid bed reactor, suited for recycling a fluidizing gas containing, in suspension, particles of solid material; comprising a gas distributor consisting of a doubleconed body or of a series of concentrical cones provided on their lateral surfaces with ribs or fins forming gas inflow channels shaped in such a way and with such an inclination as to allow the passage of the solid particles entrained in the gas flow, and such as to hinder the outflow of the solid material that has been fluidized, when the flow of the gas is interrupted.
