Abstract: A device for converting thermal energy into electrical energy has a first and second layer of thermally conductive material, and an intermediate layer of polymer material arranged between the first and second layers and having a thermal conductivity lower than the first and the second layers. A plurality of channels in which a colloidal suspension of active particles is contained is arranged inside the intermediate layer, the colloidal suspension being capable of flowing along each of the channels as a result of a temperature gradient applied between the first and second layers. Pick-up elements arranged along the channels are configured to extract electrostatic force or electromotive force induced as a response to a flow of the colloidal fluid as a result of at least one among a pyroelectric effect, a triboelectric effect, and thermomagnetic advection. Each channel forms a closed loop and has an outgoing branch and a return branch.

Abstract: A drilling machine includes a main body, a mast to mount a drilling tool, a kinematic mechanism movably constraining the mast to the main body while allowing mutual rotation. The kinematic mechanism includes an elongated component hinged at two ends. When the drilling machine is in a drilling configuration, the elongated component performs a structural function to constrain the mast to the main body. An assembling and moving equipment includes a moving element movably mounted to the drilling machine and supporting the elongated component. A moving actuator controls the relative position between the moving element and a mounting portion of the drilling machine. When the drilling machine is in an assembling configuration, one end of the elongated component is released and the moving element acts upon the elongated component. Moving the moving element relative to the mounting portion of the drilling machine causes rotation of the elongated component.
