摘要:
A temperature-sensitive label is described. The temperature-sensitive label has a container provided with means for the application on an item to be monitored and housing a temperature-sensitive system made up of a filiform shape memory member. The filiform shape memory member is restrained to a filiform bias member provided with an engaging seat, and is introduced in such a way that in case of exposure to a temperature lower than a preset critical threshold temperature (Tc), the filiform shape memory member performs a phase transition, causing an irreversible disengagement condition visible through a transparent window.

An impact resistant tool or tool bit holder has an active end for driving a fastener and a shanking end for securing to a power tool. The active end includes a body with a bore to receive the shank and a pocket to receive a damping mechanism. The shank includes an end to engage the bore in the body, and a pocket to receive the damping mechanism. The shank is received in the bore in the body for limited rotation with respect to the body. A damping mechanism is positioned in the pockets to provide damping between the body and the shank during torque loading.

An actuator (10) is described in which the functional element (11) is made of a shape memory alloy, and comprising means (14, 18) for increasing the load applied onto the functional element when the external temperature increases, thus causing a consequent variation of the transition temperatures characterizing the hysteresis cycle of said functional element.
摘要:
An actuator including a shape-memory flexible cable with a flexible sheath can be used, by controlling it both electrically and mechanically using the sheath as element for applying a mechanical tensile force. The shape-memory flexible cable is provided with a coating made of synthetic or elastomer material moulded thereon and adherent thereto, which favors rapid return of the shape-memory cable into its resting configuration after its activation both on account of its elastic return and owing to the fact that it favors cooling of the cable. Preferably, the coating is obtained by means of a process of co-extrusion with the shape-memory cable.

A household appliance comprises a cabinet, a door and a door block/release device. In normal conditions, the device is actuated by electrically powered actuator means whilst in case of need the device can be actuated by means of a release system. The device comprises an actuation element, preferably made of shape memory material, inserted within a movable body. The device is capable of passing from the condition of blocking to that of releasing the door both by means of a movement of the actuation element caused by the electrical power supply control of the actuator means and by means of a manual actuation, using the housing body as an element of manual mechanical transmission.

摘要:
An air-distribution system comprises a fluid device that enables deviation of a flow of air that traverses a main duct (6S; 6D) into a first secondary duct (7S, 7C) and a second secondary duct (7C, 7D), exploiting the Coanda effect. The system may be applied in vehicles in general, in particular motor vehicles, or for example in residential, commercial and industrial buildings.
摘要:
A propeller or fan, in particular a cooling fan, such as for the radiator of a motor vehicle or electric equipment, for civil or industrial plants, comprising shape-memory actuator means to regulate the direction and/or shape of the blades, for example according to variations in temperature.

Oscillating damper comprising: a housing (12) defining a chamber (14) filled with damping fluid, an oscillating plate (22), movable within the chamber (14) and placed so as to divide the chamber (14) into two sections of variable volume (24, 26), and at least one passage (28) created in the oscillating plate (22) to enable the fluid to pass from one section to the other during the motion of the plate (22). The damping fluid is a magneto-rheological or electro-rheological fluid and an electrically-controlled excitation device (30) is placed in correspondence with the passage (28) to control the outflow resistance of fluid passing through the passage (28).
