  • Patent number: 10471404
    Abstract: A valve for dosing and mixing two fluids includes two respective inlet ducts, a double chamber for controlling the flows, at least one actuator configured to regulate the flow rates of the two fluids to be mixed, an electronic control unit and a Brix degrees optical sensor, arranged on the mixing duct of the mixture of the two fluids and operatively connected to the electronic control unit. The optical sensor is configured to send a measurement and control signal to the electronic control unit to drive the actuator so as to proportionally control the flow rates of the two fluids and, therefore, regulate the mixing ratio of the two fluids.

  • Patent number: 10071236
    Abstract: The invention describes a total isolation diverter valve comprising a valve body whereon a main inlet conduit for inletting a fluid, a first outlet conduit for outletting the fluid and at least one second outlet conduit for outletting the fluid are obtained. The first outlet conduit for outletting the fluid is provided with a first fluid adhesion inner surface and the second fluid outlet conduit is provided with a second fluid adhesion inner surface. Between the main fluid inlet conduit and the two fluid outlet conduits a connection channel is interposed. On the connection channel at least one device for perturbing at least one of the first fluid adhesion inner surface and the second fluid adhesion inner surface is provided. The perturbation device is configured so as to cause a deviation of the fluid flow from the first fluid outlet conduit to the second fluid outlet conduit or vice-versa by exploiting a physical effect called Coand{hacek over (a)} effect.

  • Patent number: 9630560
    Abstract: A shape memory actuator includes a supporting body, a driven element pivotably mounted on the supporting body and in permanent contact with a driving element whose movement is determined by a SMA actuating member and by at least one resilient return member acting in opposition to the SMA actuating member. The driven element is able to take two stable positions under the action of a bistable moving system connecting the driving element to the driven element such that each toggling between the two stable positions is due to an activation of the SMA actuating member, the latter being arranged together with the bistable moving system. The resilient return member, the driving element and the driven element on a same side of the supporting body are in a substantially co-planar arrangement.

  • Patent number: 9512829
    Abstract: A shape memory actuator is described. The shape memory actuator has a supporting body, a driven element slidably mounted on the supporting body for movement between a stable rest position and a stable operative position, a driving element that drives the driven element, the movement of the driving element being determined by a SMA wire and by first resilient return means acting to return the driving element to the rest position upon deactivation of the SMA wire, second resilient return means acting on the driven element in opposition to the SMA wire, engaging means suitable to achieve at the operative position a reversible engagement between the driven element and the supporting body, either directly or indirectly, said engagement being able to resist the action of second resilient return means, and a control system for the engagement and disengagement of the engaging means.

  • Patent number: 9171686
    Abstract: A bistable electric switch is described. The switch has as actuators a pair of opposing SMA wires acting on a drive element integral with a snap-action spring so as to toggle the snap-action spring between two stable positions corresponding to two operating positions of the switch, the drive element being shorter than the distance existing between the two opposing SMA wires when one of the SMA wires is contracted and the other SMA wire is uncontracted. The entire force exerted by the activated SMA wire is used to overcome the resistance of the snap-action spring.

  • Patent number: 8899829
    Abstract: A temperature-sensitive label is described. The temperature-sensitive label has a temperature-sensitive system having a filiform shape memory member that has a first end portion having a terminal part fixedly secured to a first contact member, a second end portion having a terminal part restrained by a second contact member in a non-permanent way, and a central curved portion. The central curved portion is in the martensitic phase while the first and second portions are in the austenitic phase at a same environmental temperature above a critical threshold temperature to be monitored by the label such that in case of exposure to a temperature lower than the preset critical threshold temperature the end portions of the filiform shape member perform a phase transition, from austenitic phase to martensitic phase, which causes its irreversible disengagement from the restraint formed by the second contact member.

  • Patent number: 8870082
    Abstract: 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.
