A fastening device is described for footwear provided with a first and second flap to be closed, comprising: - a first flexible member extending between a first and second point on the footwear, - a second flexible member extending between a third and fourth point on the footwear so as to close the flaps against each other when pulled, wherein the first flexible member is connected to the second flexible member to pull it and thus close said flaps against each other, the third point is anchored to one of the flaps, and the fourth point is coupled to a portion of the first flexible member which is located between the first and second points and at which portion the first flexible member has a change of direction; - means for tensioning the first flexible member so as to rectify/straighten said portion and consequently pull the second flexible member so as to close the flaps.

A method for producing a metal object by 3D-printing and subsequent precision machining is described. The method comprises the step of attaching interconnection members to the external surface of a 3D-printed metal object, wherein the interconnection members applied to the object are capable of cooperating with corresponding interconnection members provided on a processing plane of a CNC machine, so as to be able to position the object on the processing plane in a controlled manner with respect to a positional reference system of the CNC machine.

A control method is described for a heating device (10) placed inside an auxiliary cavity (18) that is formed in a mold plate, is bounded by side walls (24), and comprises a terminal wall (20) that delimits on the other side thereof a molding cavity for injection and molding of molten material. The method has the step of heating the terminal wall by the heating device as a function of a signal emitted by a temperature sensor (50) mounted to detect the temperature of the terminal wall.

A method is described for mounting a closing device on a ski boot that comprises a shell (12) and a tubular cuff (14), wherein the closing device functions to bring two flaps (16, 18) of the shell and/or cuff closer to each other, and the cuff comprises a rim (13) that in use ends up substantially at the ankle joint of the person wearing the boot. To minimize the bulk overall, the method has the steps of 1. fastening the closing device (10) to the shell or cuff; 2. placing the rim (13) on the closing device so that the rim at least partially covers the closing device; 3. connecting a retaining member (160) to the closing device to trap the rim between the retaining member and the closing device.

A monitoring method is described for an injection molding system, with the steps of 1) closing an injection nozzle (20) by moving a valve pin (30) towards the injection nozzle (20), and through a sensor (60) acquiring data indicative of the actual position of the pin (30) when it has reached an end-of-travel position thereof towards the nozzle (20); 2) obtaining a comparison value from the acquired data and comparing the comparison value with a reference value, and 3) emitting a signal if the result of the comparison indicates that the actual position is further from the nozzle (20) than the reference value.

A software-implemented method is described for controlling the welding laser of a welding machine comprising:- a laser source for generating a laser beam with adjustable spot and engraving the surface of an object;- a power stage for driving the laser source;- a control circuit for controlling the power stage and setting laser parameters during the laser action;the method comprising the steps of:1) acquiring a first value that expresses a selection relating to the type of material to be worked with the laser;2) acquiring a second value that expresses a selection relating to the size of the spot generated by the laser beam on the object;3) calculating a power value of the laser pulse emitted by the laser source as a function of the first and second value;4) calculating a duration value of the laser pulse emitted by the laser source as a function of the first and second value;5) generating control signals for the control circuit to set the laser power to the power value calculated in step 3) and the laser pulse duration to the duration value calculated in step 4);6) sending the generated control signals to the control circuit.

A liftable bed installed in a compartment is describer. The bed comprises a platform and an ironing board. The platform is rotatable about a first horizontal axis, integral with the compartment, and configured to vary its own inclination from vertical, in which the platform is inside the compartment, to horizontal, in which the platform is extracted from the compartment and acts as a bed, or vice versa- The ironing board is pivoted on the platform about a second axis parallel to the first axis, and is configured to vary its own inclination so as to be able to arrange itself either parallel or substantially orthogonal to the platform.

A method for enlarging the padded surface, such as a mattress, of a structure by placing a cot next to the structure, whereinthe structure comprises a first mattress raised from the ground, andthe cot comprises:a second mattress,a platform to support the second mattress andground-support legs that can be deployed to lift the platform;with the steps of- extracting the cot from under the structure,- placing the cot next to the structure,- lifting the platform and the second mattress by deploying the legs,- bringing the second mattress flush with the first mattress by adjusting the length of the legs.

A method is described for producing a composite object (10) by hot molding, with the steps of- providing a first solid core (14) molded with expanded cellular material,- depositing a first lamination (16) of resin-impregnated hardening material over the external surface of the first core, where the first lamination comprises a first portion (20) and a second portion (22) which is an extension of the first portion;- applying a filler material, distinct from the first core (14) , only on the external surface of the second portion;- depositing a second lamination of resin-impregnated hardening material to envelope the assembly given by the first core, the filler material and the first lamination,so that, once the laminations have been completed, in the molded objectthe filler material ends up placed between the internal surface of the second lamination and said external surface, andthe first portion is in contact with said internal surface;- solidifying by curing in a mold the laminations so thatthe second lamination creates a rigid outer shell (12) of the object that envelops the first lamination, the first core and the filler material, andthe first lamination creates an internal reinforcement of the object.

A method is described for detecting the presence of hydrogen in the oxygen stream generated by a PEM cell, wherein the PEM cell comprises a membrane permeable to H⁺ ions , a first inlet conduit for water, a second outlet conduit for hydrogen, and a third outlet conduit for the generated oxygen. The hydrogen and the oxygen being produced by the molecular dissociation of water inside the PEM cell.In the method the temperature of a catalyst placed in contact with said oxygen stream, is detected.
