Abstract: A helmet for displaying environmental images in critical environments, comprising at least one video camera and a display for displaying environmental images; the helmet also has a supporting structure that can be anchored to the helmet in order to support the at least one video camera and the display; the supporting structure has a front adapter that can be coupled to a front edge of the helmet, a rear adapter that can be coupled to a rear edge of the helmet, and a connecting element for mutually connecting the front adapter and the rear adapter.

Abstract: A vacuum cooking apparatus for household use, comprising, on a supporting structure which has a column-like extension, at least one unit for packaging in pouches in vacuum food products to be cooked, at least one unit for cooking the food products arranged in pouches and at least one unit for quick refrigeration of the food products arranged in pouches and cooked, the at least one unit for packaging food products in pouches in vacuum comprising a vacuum packaging machine which is mounted on a drawer-like element which is supported so that it can slide by the supporting structure in order to pass from a retracted position, in which the vacuum packaging machine is arranged within the outer peripheral contour of the supporting structure, to an extracted position, in which the vacuum packaging machine is positioned at least partially outside the supporting structure, and vice versa.

Abstract: A static switch for DC motors of climate control units, comprising a signal side and a power side, which are mutually separated by means of optoisolators, the side comprising in input at least one terminal for a motor on/off signal and a terminal for a pulse width modulation signal PWM to provide the amplitude modulation, on the power side, of a motor speed signal, the switch comprising a precharging device which has a control terminal connected to a power-on optoisolator and a precharging current supply terminal connected to a motor power supply pole, the switch further comprising at least one power-on transistor connected to the same motor supply pole of the power supply terminal of the device, so that a voltage applied across the power-on transistor that exceeds a certain threshold switches off the motor power-on transistor.

Abstract: A machine for in-register mounting of flexographic printing plates with a virtual data-processing system, having a supporting footing for a printing plate cylinder, on which a respective flexographic printing plate is mounted, suitable for printing a predefined image, and at least one television camera, which is connected to a monitor, is trained onto the cylinder and can slide parallel to the cylinder to check correct positioning-mounting of the printing plate, the television camera being associated with position sensors and connected to a device for the real-time processing and display of at least one composite image, for allowing the operator to perform precise position comparisons for optimum plate mounting between a preprocessed graphical reproduction of the image to be printed, provided on a digital memory composed of graphical memory associated with position measurements, and the position of the printing plate.

Abstract: A gym machine comprising a ground resting base, a structure for supporting a user which is associated with the resting base so that it can rotate about a rotation axis, at least one maneuvering body which is associated movably with the supporting structure and flexible elements which are stretched between the maneuvering body and the ground resting base, the supporting structure rotating about the rotation axis between a first configuration and a second configuration when a user supported by the structure moves the maneuvering body, applying to the maneuvering body an action which is opposite with respect to the action applied thereto by the flexible elements.

Abstract: A cutting machine, particularly for leather and similar materials, comprising a pair of shoulders which are connected by a system of guides arranged so as to lie above a conveyor belt, at least one cutting head being movable along the guide system, the movement of the cutting head in the same advancement direction as the conveyor belt and at right angles to the guide system being distributed on two or more elements, at least one of which is cantilevered.

Abstract: A device for analyzing defects, particularly for items made of plastics, such as battery casings and the like, comprising at least one probe, which is adapted to be moved closer to, or to come into contact with, the item made of plastics to be tested, the probe being provided with a plurality of elements to which a high voltage is applied.

Abstract: The present invention relates to a method for preparing a porous ceramic material, particularly for thermal insulation, comprising the steps of: providing a first composition in the form of a stable aqueous colloidal solution of silica and oxides of alkaline metals; providing a second stable composition in the form of a suspension in an organic liquid of inorganic and/or organic particles, the second composition containing compounds which, when the second composition is mixed with the first composition, can destabilize the first composition, forming gel, and can form an organic polymeric net together with a blowing agent; mixing the first composition and the second composition to form a mixture; forming from the mixture a porous structure in gel form, where an organic structure supports inorganic structures being formed; solidifying the porous structure in gel form, obtaining a porous ceramic material in which an organic polymeric net surrounds inorganic portions.
