Abstract: A package closure system has a frangible radiofrequency identification label which is protected from the external environment by a cover and the frangible label is damaged preventing its normal operation when the package cover is removed. More specifically, a package closure system has a cover, a metallic induction seal attached to the package nozzle and a frangible radiofrequency identification label in which the frangible radiofrequency identification label is attached directly or indirectly to one of its parts on the inner portion of the cover and on another part on the outer portion of the metallic seal.

Abstract: Package closing system and package authentication system comprising cover (4), seal (3) attached to the package nozzle (2) and “frangible” type radiofrequency identification label (6), characterized by the “frangible” type radiofrequency identification label (6) to be attached directly or indirectly to one of its parts on the inner portion of the cover (4i) and on another part on the outer portion of the seal (3e), so that the opening of the cover (4) leads to the destruction of the “frangible” type radio frequency identification label (6).

Abstract: A method of relative positioning between agricultural machines and crops on their planting rows having the steps which are performed in real time and during a harvest work and include determining a positioning of each tree top on a trees row, a machine rotor column position, and simultaneously a traveling speed of an agricultural machine, sending tree positioning and machine speed data to a data processor, processing the data and controlling servo mechanisms that actuate actuators which, in turn, place one rotor column with stripping rods in accordance with a determined tree top position and format.

Abstract: For relative positioning between an agricultural machine and crops on their planting rows a sensor is arranged forwardly of a sensor of a rotor of an agricultural machine and at a distance which is at least equal to or greater than a top radius of trees to be worked with the radius being measured in a planting row direction, the tree top by the sensor to determine a rearward point, a forward point, a center point and a farthest transverse point from the center point of a tree top, and the rotor is adjusted to define a trajectory of the rotor center with respect to the points, whereupon the steps are repeated for each of the trees in the planting row to be worked.

Abstract: A mechanical transmission for agricultural vehicles of adjustable track width has gear cases disposed vertically to elevate a chassis height of vehicle above a plantation, rear axles provided for wheels of the machine and mounted to the gear cases, first gears and second gears located in the gear cases and coupling the axles and also being interconnected with one another, a differential to which torque is transmitted from the axles through the second gears which are upper gears, a cross tube, the gear cases having substantially first horizontal extensions which are fitted on the cross tube so as to allow sliding outwards or inwards of the extensions in order to modify a machine track width, the differential having two second extensions, grooved shafts which are fixedly connected to the second gears, first tube bushings which are connected with the gear cases and in which the grooved shafts are fitted, second bushings having internal grooves and surrounding the grooved shafts, tubes which are fixed to the gear

Abstract: A dynamic counterweight mechanism for one-sided sprayers is vertically fastened to a chassis of a conventional sprayer with a fixed frame (3) so as to move up and down in relation to the frame (3). The mechanism includes a sliding frame (20) that laterally sustains a counterweight module (30). A swinging module (40) is pivotally assembled on the opposite side (23) of the sliding frame (20) and rotates around a bearing (24, 43) and in relation to the sliding frame (20). The upper end of the swinging module (40) is connected to the counterweight module (30) by a steel cable (33), which, in turn, has a counterweight block (32) that moves up and down, due to displacement of the swinging module (40). The steel cable (33) extends through a set of sheaves (50, 51, 52, 53) between the swinging module (40) and the sliding frame (20).

Abstract: A spraying apparatus for spraying agricultural chemicals over shrubbery and small size trees and plants in early stages of their growth positioned in arrays with empty areas therebetween, has a storage for an agricultural chemicals to be sprayed, a spraying assembly having the shape of an upside down “U” and provided with a plurality of spraying nozzles, a detector for detecting the presence of a plant, and an activator for activating the spraying nozzles, after the detector detects a plant, to spray the plant inside the spraying assembly, the spraying assembly having a substantially flat frame composed of a plurality of substantially flat elements.
