Abstract:
A stop device with a shape memory actuator includes two stop elements sliding within a fixed support structure and usually hold in their mutual distant position by cam means pushed through spring means. A shape memory actuator is started through an electric current passage for causing the displacement of the cam means in a position wherein they permit the backward movement of the two stop elements towards a mutual close position.
Abstract:
Described herein is a motor-vehicle suspension of the type with oscillating arms, in which one of said arms is formed by the casing of a rotational shock-absorber, the oscillating piston of which is connected to the structure of the motor vehicle. Preferably, the casing of the rotational shock-absorber is also used for the anchorage of a respective end of a leaf spring, which constitutes the elastic element of the suspension.
Abstract:
An air-mixing system comprises a fluid deflector device with analogical operation which enables continuous regulation of the distribution of a main flow coming from a main duct into two secondary ducts.
Abstract:
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.
Abstract:
A shape memory actuator includes a shape memory actuator element for biasing an actuated member from an initial rest position to an operative position against the action of return spring means. Holding means are associated with the actuator element for holding the actuated member in its operative position even when the shape memory actuator element is deactivated. These holding means can be deactivated with a subsequent activation of the shape memory actuator element, allowing the actuated member to return to its rest position.
Abstract:
Lock for doors, for example door of homes, offices, hotel rooms or similar, as well as doors of motor vehicles, comprising lock opening control means, comprising a control device located at a distance from the lock and a mechanical transmission connecting the control device to the lock. A shape memory actuator being arranged in between said mechanical transmission, so that the lock can be opened both by operating the shape memory actuator, and by operating said control device, in which case the shape memory actuator works simply as a mechanical transmission element.
Abstract:
VTOL aircraft comprising a first and a second ducted rotor positioned at the ends of a vertical fuselage and whose propellers are driven to rotate in mutually opposite directions. Control flaps for orientation and transverse flight are operatively associated at least to the lower ducted rotor.
Abstract:
Described herein is an air-distribution device which uses means designed for causing deviation, by Coanda effect, of a flow of air coming from an inlet duct into a plurality of outlet ducts. The invention is applicable both to a motor-vehicle air-conditioning assembly, which incorporates a conveyor with a heating element, and to a motor-vehicle dashboard.
Abstract:
The object of the invention is a collection device that can be carried by disabled persons, comprising a section of duct, destined to be connected to the rectum of the person, an expansible container, connected to said section of duct, and a shutter device interposed in the aforesaid section of duct and controlled by actuator means, for example shape-memory or electromagnetic means, activated by the signal of a sensor.
