20090111623 | PULLEY ASSEMBLY WITH AN IMPROVED CLUTCH FOR A CONTINUOUSLY VARIABLE TRANSMISSION - A pulley assembly for a continuously variable transmission in a vehicle, comprising a shaft having an axis, a supporting element rotatable about said axis, a first half pulley rigidly and rotationally connected to said supporting element, a second half pulley facing said first half pulley for defining a seat adapted to accommodate a belt of the transmission, at least one of the first and second half pulleys being longitudinally mobile with respect to the supporting element, and a clutch comprising a second supporting element connected to the shaft, a drum connected to the supporting element and accommodating the second supporting element, and a plurality of friction elements hinged to the second supporting element about respective hinge axes to selectively cooperate with the drum. In particular, the respective centres of gravity of said friction elements are located before the respective hinge axes with respect to a direction of rotation of the shaft which defines a forward running condition of the vehicle. | 04-30-2009 |
20090156338 | Pulley Assembly for a Continuously Variable Transmission - Pulley assembly for a continuously-variable vehicle transmission, comprising a support element having an axis, a first half-pulley rotationally connected to the support element, a second half-pulley facing the first half-pulley to define a seating adapted to house a drive belt, the second half-pulley being axially and circumferentially mobile in relation to the support element, and cam means functionally inserted between the second half-pulley and the support element to control the position of the second half-pulley. The cam means define a plurality of circumferential cavities carried by a peripheral portion of the second half-pulley, said cavities being defined by the first and second sides which are transverse to axis, and comprise a plurality of cam-followers which are connected to the support element and housed in the corresponding circumferential cavities to cooperate selectively with the first and second sides. | 06-18-2009 |

20090250241 | Cable and process for manufacturing the same - A cable for applications which entails heavy mechanical stresses and/or harsh environmental conditions includes at least one core having at least one transmissive element and an outer sheath disposed in radially external position with respect to the core. The outer sheath includes a reinforcing layer including a fibril reinforced polymeric matrix. A process for manufacturing such a cable includes the steps of providing a core having at least a transmissive element; providing a first compound of fibrils and a matrix; and applying the first compound around the core to form the reinforcing layer including the fibril reinforced polymeric matrix. The invention also deals with the use of fibrils for the manufacturing of a coating layer for a cable. | 10-08-2009 |

20100051315 | POWER TRANSMISSION CABLE - A power transmission cable comprising at least one power conductor, an insulating layer surrounding said conductor to form at least one insulated conductor, a flame-retardant halogen free protective sheath provided in a radially external position with respect to said insulated conductor, wherein said sheath has an inner and an outer layer in contact one another, said inner layer has a thickness at least equal to a thickness of said outer layer, the inner layer comprises a polymer material having a glass transition temperature equal to or lower than −30° C., and the outer layer comprises a mud resistant polymer material. | 03-04-2010 |
20110017509 | ELECTRIC ARTICLE COMPRISING AT LEAST ONE ELEMENT MADE FROM A SEMICONDUCTIVE POLYMERIC MATERIAL AND SEMICONDUCTIVE POLYMERIC COMPOSITION - An electric article, particularly an electric cable or an accessory thereof, such as a cable joint or a cable termination, includes at least one element made from a semiconductive polymeric material, wherein the at least one element is obtained by crosslinking a semiconductive polymeric composition including: (a) at least one elastomeric polymer; (b) a filler mixture including: (i) at least one first carbon black having a dibutyl phthalate (DBP) absorption number of from 250 to 600 ml/100 g; (ii) at least one second carbon black, different from the first one, having a dibutyl phthalate (DBP) absorption number of from 80 to 250 ml/100 g; and (c) at least one graphite having a specific surface area, measured according to the BET method, not higher than 20 m | 01-27-2011 |
20150284528 | PROCESS FOR RECOVERING WASTES OF A POLYMERIC COMPOSITION INCLUDING A PEROXIDIC CROSSLINKING AGENT - A process for recovering wastes of a polymeric composition including at least one peroxide-curable polymer and at least one peroxidic crosslinking agent, which includes compounding the wastes with at least one antioxidant agent suitable for sulfur-vulcanized elastomeric compositions, at a temperature lower than the decomposition temperature of the at least one peroxide crosslinking agent. These antioxidant agents are effective to quench the peroxide crosslinking agent, so as to avoid any substantial crosslinking of the composition during processing of the same. The compounding of the polymeric wastes with the antioxidant agent is carried out at a temperature lower than the decomposition temperature of the peroxide crosslinking agent, so as to avoid any premature activation of the crosslinking agent. The process is particularly suitable for compositions based on elastomeric polyolefins, more preferably for elastomeric ethylene copolymers such as ethylene-propylene copolymers (EPR) and ethylene-propylene-diene terpolymers (EPDM), which can be processed at relatively low temperatures, much lower than the decomposition temperatures of the most common peroxide crosslinking agents. | 10-08-2015 |
