Abstract: A track unit for moving a ground work vehicle, comprising two elastic elements proximate to the front and rear ends, interposed between a monolithic upper portion of the structure that supports the driving wheel and a monolithic lower portion that supports two pairs of coaxial guiding wheels with parallel axles and resting rollers, means adapted to ensure a coplanar arrangement of the upper and lower portions of the structure being also provided.

Abstract: An aircraft comprising an elongated framework provided with propelling means and direction-control planes. The framework is coupled to a pneumatic chamber suited to be filled with lighter-than-air gas and comprising two tubular branches joined to form a V-shaped profile, with an aerodinamic-lift surface extending therebetween.

Abstract: A sheet-like element, such as a net, particularly for geotechnical applications, comprising a sheet-like body formed by superimposing at least two sets of filaments in order to provide a lattice-like structure, the sheet-like body being provided by a first polymer, which defines the lattice-like structure, and a second polymer, which is coextruded together with the first polymer and affects at least regions of at least one face of the sheet-like body, the first polymer having physical and mechanical characteristics of compressive and tensile strength, while the second polymer has a high friction coefficient.

Abstract: A spreading head particularly for spreading one or more adhesives or mixtures of adhesives, of the hot-melt or cold type, comprising a body for conveying the one or more adhesives to an extrusion tool; the body has two or more ducts, which are all separate or of which two or more converge, and the tool has one or more first extrusion channels and/or one or more mixing chambers which are connected to one or more second extrusion channels, the first and/or second extrusion channels being optionally mutually superimposed and/or laterally adjacent.

Abstract: A binding for fixing a shoe to a snowboard and the like comprising a base body that can be fixed to a snowboard and the like by an angular positioning disk with engagement of contact elements defined by the base body on the snowboard, elements for fastening a shoe being associable with the base body and elastic shock-absorbing elements being also associable and interposable between the snowboard and the like and the base body, the shock-absorbing elements at least partially surrounding the external lateral profiles of the rear region of the base body.

Abstract: A sports shoe which comprises a rigid sole from which a shell protrudes, starting from a forefoot region and up to a heel region, a quarter being rotatably associated with the shell. An insole is slidingly associated within the shell, at a bottom thereof, is provided with a tip and interacts with elements for adjusting and guiding its axial position with respect to the shell.

Abstract: A machine for filling containers with liquid product, comprising a rotating carousel provided with a plurality of filling stations, means adapted to provide selective feeding by means of a hot fluid and by means of the product, and means adapted to collect and evacuate the hot fluid that exits from the faucets, all the walls of the machine designed to be in contact with the hot fluid and the liquid product having high thermal insulation characteristics.

Abstract: A mechanism for the installment of a door or other similar closure having a rotational-sliding movement, of the type comprising the following elements to associate to a shutter: first pivot means defining a first vertical axis for the pivoting of a shutter, in a substantially central region thereof, to translation means arranged so as to slide in a corresponding guide associated to the upper strut of a frame of a door; second pivot means with an axis parallel to the axis of the first pivot means, for the pivoting of two arms, a first upper one and a second lower one, that are both pivoted with one of their ends to the frame of the door or closure in proximity to a jamb to define a second rotation axis, and have the opposite ends reciprocally rigidly coupled by means of a rod, defining a third rotation axis interposed between the first axis and the second axis, passing through the shutter in the direction of the height thereof.

Abstract: A machine for filling containers, comprising dispensing heads, in which each dispensing head comprises at least two ports, which are connected to respective ducts for feeding different liquids, and is provided with elements for controlling the flow of the ducts which are controlled by automatic control elements which act as a function of the quantity of the individual portions of the different liquids that are meant to be introduced in a container, and are adapted to produce a sequential opening of only one of the ports, so as to fill each container by preset portions of the liquids which access sequentially the container.

Abstract: The tension is modulated by a weft-braking device controlled by a tension control block programmed for comparing the measured tension with a reference tension, and for transmitting a braking level signal to the weft-braking device, which braking level signal is adapted to minimize the difference between the measured tension and the reference tension. The yarn consumption speed is calculated, then the yarn consumption speed is compared with a predetermined threshold speed, and if the calculated consumption speed overcomes the predetermined threshold value, the tension control block is enabled, while, if the calculated consumption speed is lower than the threshold value, the tension control block is disabled and the last signal generated by the latter is maintained as braking signal, until the yarn consumption speed overcomes again the threshold value.

Abstract: A cutting and transfer drum in a continuous-film labeling machine, which allows disassembly into sectors comprised between two contiguous blades, each sector being provided with elements for locking in the active position, which comprise a rotating rod which is provided with an actuation crank, said rod having a portion which is adapted to mate with a reference element provided on the sector, elements adapted to retain the sector in the locking position, a cam adapted to make contact with an abutment provided on the sector, so as to ensure a contact pressure of the sector on a supporting ring which ensures the retention of the fluid that provides suction.
