A bending transducer device for generating electrical energy includes at least one elastically deformable support structure, one piezoelectric element, and a bearing device. The piezoelectric element is configured and situated on the support structure in such a way that the piezoelectric element is deformable due to a deformation of the support structure caused by vibration, and the support struct...

The method involves distributing equal sections of pressed material mat (2) to a press by a distributing device (8), and adjusting increase of mass per unit area longitudinal to production direction for manufacturing a differential flat weight profile by reception of a grit (35) in a track. An increase of another mass per unit area is controlled transverse to production direction for manufacturing...

An external rotor motor, composed of at least a stator with a stator core, coil winding, and insulating housing; a rotor; a plurality of bearings; and a rotating shaft. The rotor is disposed outside the stator and connected to the rotating shaft. The rotating shaft is disposed on the stator via the bearing. The coil winding is wrapped on the stator core. The stator core and the coil winding are di...

A hot water heater comprises a hot water tank, a supply pipe to be connected to the public water mains and a discharge pipe to be connected to a tap. The hot water tank has a circumferential wall which encloses the interior of the tank and which is provided with a heating element disposed inside the hot water tank and with a temperature control device. The circumferential wall of the tank comprise...

A device for removing a liquid or solid particles from at least one flat surface of metal products, such as strips, sheets, blooms or billets, exiting from rolling mill stands which allows a perfect, uniform removal of the emulsion and the total drying of the product thus eliminating the problems of quality deriving from the permanence of the emulsion on the finished product. The device, object of...

Apparatus for improving the safety and recovery of wells to be installed in oil wells comprising a Deep Set Well Head (DSWH), a Casing Receptacle (1), a Deep Set Tubing Hanger (DSTH) (2), Sub-Surface Safety Valves (SSSVs) (12) (13) with one or two independent Control Lines and Connection elements between the DSTH and well head
