A method of changing or placing a tread belt 512b onto a two piece tire carcass 514 is described. The method involves jacking the vehicle 600 up so the whee l clears the ground deflating the carcass 514 and pulling a vacuum to partially collapse the carcass 514, placing the tread belt 512b about half way onto the carcass 514 to support the tread belt weight lifting or pushing the tread belt 512b t...

A shipping (1) container for transporting cargo, comprising a track (5) having a rectangular floor and vertical stanchions (30) mounted at its corners with two opposite end walls (35) extending therebetween, and one or more side walls (50) having side edges with at least a portion corresponding in shape to the stanchions to interact therewith for detachably attaching the, or each, side wall to the...

A fitting tool (1) for installation of a drive belt (7) on a pulley (2) comprises a guide element (11) provided with at least one curvilinear resting wall (17) for a working surface (30) of the belt (7) and with side-guide means (24) for laterally guiding the belt (7), said means being designed to exert an axial thrust on the belt (7) in response to a rotation of the pulley (2), said fitting tool ...

A high-efficiency generator for generating pairs of photons, having a type-one crystal (3) receiving a laser pump beam at the input and generating pairs of photons of like polarization at the output; a first and a second polarization at the output; a first and a second polarization at the rotator (20a, 20b), which respectively receive the photons in each generated pair; a beam splitter (17), which...

A device for generation and weighted distribution of entangled photons between four users wherein a type-two crystal (3) receives a laser beam (12) to generate pairs of photons (f) of opposite polarizations by parametric down-conversion. Conveying mirrors (14a, 14b) are provided to reflect then generated photons to first and second inputs (17a, 17b) of a beam splitter (17), which transmit a percen...

The present invention relates to an improvement to the ends of three-dimensional electrowelded metallic lattice girders suitable for manufacturing floors in the building sector and in the industrial prefabrication sector. The rods (4) for connection among the longitudinal members are arranged vertical at the end of the lattice girder (1.1), then the upper longitudinal member (2) is shortened, and ...

A heat exchanger (1) for heating devices, such as for example boilers, comprises a plurality of pipes (10) inserted in a containment structure (50) and traversed by a first fluid. The containment structure is traversed internally by a second fluid introduced and emptied out by means of appropriate openings (80, 90). Said pipes (10) have externally a longitudinal finned portion and are inserted in ...

A motorized control (1) for low-voltage switches, comprising a servomechanism (10), a control unit (20), and a coupling lever (30) associated to said servomechanism (10) and to a switch. The servomechanism (10) is controlled through impulse signals sent by the control unit (20) and performs pre-defined rotations that enable a movement of the coupling lever (30) between two pre-set positions charac...
