摘要:
A casing (1; 50) for openings of buildings with enhanced thermal insulation capacity comprising a first tubular section (2; 51) which is fixed to the perimetrical wall delimiting the opening, and a second tubular section bar (3; 52), cooperating with the first section bar (2; 51) in order to hermetically close the opening and capable of supporting one or more front panels (4, 5) of interface between the inner environment and the outer environment of the building. At least one of the first section bar (2; 51) and the second section bar (3; 52) presents a plurality of through openings (6; 53) which create within at least one of the tubular section bars (2, 3; 51, 52) a continuous flow of circulating air which, due to the temperature difference between the inner environment and the outer environment, forms a natural thermal barrier in any astronomical season.

摘要:
A device for feeding a web of a packaging material along a path and towards an application station; wherein the packaging material comprises a plurality of pre-laminated holes at which application station applies respective opening devices. The device comprises an advancing mechanism for advancing the web along a first direction parallel to path; a sensor for generating a plurality of measure signals associated to the positions of pre-laminated holes; and a first motor controllable on the basis of measure signals. The first motor is operatively connected to the advancing mechanism for moving the advancing mechanism along a second direction transversal to path.

A process for carrying out a packaging for food stuffs, such as hazelnuts, dried fruits, or powdered milk, packaged in bulk, comprises the steps of: —provision of a big bag container (2), —carrying out a filling of the above said product (P), into the big bag container (2), —provision of a seal enclosure (3) susceptible of containing the big bag container (2) with the above said filling of product (P) therein, and—sealing the enclosure (3) containing the big bag container (2), with the above said filling of product (P) therein, a sub atmospheric pressure level. Preferably, a protective inert gas, such as nitrogen, is inserted into the enclosure (3) containing the big bag container (2).
摘要:
A rotary-percussion device for directional drilling in rock comprises a substantially cylindrical, rotatable body portion (15) housing a percussion hammer, and a frustroconical head (2) eccentrically mounted on the front of the body portion. The minimum diameter face (3) of the head is adjacent to the body portion. The axis (6) of the head is parallel to but offset from the axis (5) of the body. The front face (4) of the head is chisel-shaped and comprises at least one oblique plane (11) sloping forwardly in the same direction as the offset of the head axis relative to the body axis.
摘要:
A natural thermal cut window and door frame (1) comprising a first section bar (2; 51), suitable to be fixed to the perimetric wall delimiting a room of a building, and a second section bar (3; 52) cooperating with said first section bar (2) in order to hermetically close the room itself, a pair of front panels supported by the second section bar (3), suitable to form the interface between the outer environment and the inner environment of the building. In particular, each of the aforesaid section bars (2, 3; 51) is composed of at least two shaped portions (4, 5; 53, 54) distinct and independent each other, connected each other through union means (6), in order to define between the shaped portions (4, 5; 53, 54) a thermal insulation slot (7) suitable to allow air circulation from/to the outer environment to/from the inner environment, and provided with reinforcement means (8) suitable to assure structural rigidity.
