摘要:
A method for rendering cultivatable a plot of rocky ground comprising a grinding step, wherein a surface layer of the ground is subjected to grinding with a mechanical milling machine until what is obtained is a mixture of dust, stones and, if present, soil, the surface layer which is subjected to grinding covering, starting from the surface of the ground, a depth which is greater than or equal 40 cm; at least one boring step wherein a plurality of holes is made in the ground which extend vertically with a depth of at least 50 cm below the surface layer subjected to grinding, the holes being spaced relative to each other; at least one inserting step wherein at least one explosive charge is inserted in each hole; and at least one detonating step wherein the explosive charges are detonated; wherein the detonating step causes the formation, in any rocky base, of cracks which allow water drainage towards deeper layers of earth.

Pack comprising a tray (1) constituted of a flat sheet of multi-layer material, with one paper-based lower layer and one plastic material upper layer, which has a perimetric edge (2), and an elongate cut (3) that extends near the perimetric edge and is spaced from it, wherein between the elongate cut and the perimetric edge a portion of the flat sheet is identified which defines a frame (5) that at least partly surrounds an inner part (6) of the flat sheet on which a food product is positioned; at least one protective film (12) fixed to the tray at both a first connecting zone (13) that extends continuously on the inner part of the flat sheet in a closed ring that surrounds the food product, and at a second connecting zone (14) that extends at least along the frame and externally relative to the first connecting zone.
摘要:
A manually operated fastener for the side boards of vehicle bodies comprising a hollow containment casing (3) having a main axis of extension and a main opening (5) and a secondary opening (7), which are transversal to each other, for accessing the inner cavity (4), an insert (9) slidably inserted in the containment casing (3) and a first connecting element (10) connected to the insert (9); when the insert (9) is in a first position the first connecting element (10) is positioned in its own locking position, and when the insert (9) is in a second position the first connecting element (10) is positioned in its own releasing position; the first connecting element (10) is also movable relative to a first part (15) of the insert along a line of translation perpendicular to the main axis of extension, between a back position and a forward position and there are thrust means (16) acting on the first connecting element (10) for elastically pushing it towards the back position.
摘要:
A fastener for the bodies of commercial vehicles, comprising a rotatable bar (4) on which there are non-rotatably mounted at least one engaging element (5) comprising a connecting body (7) fixed to the bar (4) and an engaging projection (8) engageable with a contact element (9), and an operating lever (6) also comprising a connecting body (11) fixed to the bar (4) and a handle (12), wherein at least one connecting body (7), (11) comprises a main hole (13) in which the bar (4) is inserted, and at least one first fixing through hole (14) intersecting the main hole (13), and the bar (4) comprises at least one second fixing through hole (15) axially aligned with the first fixing hole (14); a permanent coupling element (16) is also present, comprising a pin (17) constituted of a shank (19) comprising a first end (20) equipped with an enlarged head (21) and a second end (22) to which a locking collar (18) is rigidly connected, the shank (19) being inserted with interference fit both in the first fixing hole (14) and in the second fixing hole (15). A method for mounting the connecting body on the bar is also claimed.
摘要:
A method for making a containment element that has a bottom wall (3), a lateral wall (4) connected at the bottom to the bottom wall (3) and a shaped perimetric flange that extends outwards from an upper part of the lateral wall (4), wherein the method comprises a thermoforming operating step in which a flat sheet is thermoformed and the bottom wall (3), the lateral wall (4) and an annular band (2) that projects outwards from the upper part of the lateral wall (4) are created and, subsequently, a hot bending operating step for bending the annular band (2), dividing the annular band (2) into a first annular portion (6) and a second annular portion (7) which are concentric and are not coplanar, after the hot bending the annular band (2) constituting the shaped perimetric flange. An apparatus and a machine able to implement all or part of that method are also claimed.
