摘要:
An actuator device is described, apt at varying its functional condition from a state of rest to a working state, both stable, comprising a body (2,3) of contained dimensions, within which the following are housed:
actuating means, comprising a thermal actuator (5), an electric heater (6), electric contacting elements (7) and a transmission shaft (10,11) of the thrust generated by the actuator (5); means for maintaining the working state, also in absence of electrical supply to the actuating means, comprising bistable kinematic motion (20-30) of inclined planes and/or cams.
摘要:
A hybrid type programmer comprising a microprocessor is described, for washing machines, in particular dish-washing machines; the main characteristic of the described programmer consists in that the microprocessor periodically receives amounts of information, concerning the state of a single electromechanical switch, commanded by a cam, activating a certain organ, and elaborates such information in order to control the advancement of the machine's operative program.

The present invention relates to a display system of television images by way of projection; the main characterising principle of the invention consists in the fact that a plurality of projectors are employed, each projecting the same image on the same screen, and that every single projector projects the image in a different instant.
摘要:
The present invention relates to a tuning method for voltage synthesis television signal receivers; the main characteristic of the invention consists in that a plurality of digital codes, each identifying respectively a voltage corresponding to a television channel, are memorised before the sale of the receiver in a tuning memory (15) of the non volatile digital type, to a corresponding plurality of addresses and that for executing the direct call of the desired channel the user types on a command unit (16) the channel number, that said command unit (16) sends to a control unit (14) of the receiver a corresponding signal and that the control unit (14) reads in the memory (15) the corresponding digital code and sends it to the tuning unit (10) that provides for tuning the desired channel.
摘要:
A dispenser device for liquid and/or powder agents for a washing machine is described, in particular a dispenser device (1) for a domestic dish-washing machine, of the type comprising a first (4) and a second (3,5) delivery device of washing agents which have to be introduced in a washing chamber at distinct moments and/or washing phases, the delivery of said washing agents being controlled from a command system comprising a single actuating device (19,20) and a kinematic element for the actuation at different times of the first (4) and of the second (3,5) delivery device. The main characteristic of the described dispenser device (1) is that the kinematic element (17,18) comprises a cam (27) which, after a first actuation of the actuating device (19,20), determines a movement of the kinematic element (17,18) being able to activate the functioning of the first delivery device (4) without causing the functioning of the second delivery device (3,5), while after a second actuation of the actuating device (19,20), said cam (27) determines a movement of the kinematic element (17,18) being able to activate the functioning of the second delivery device (3,5).
摘要:
The present invention refers to a transmission and reception system of television signals, in particular of the digital type; the main characteristic of the invention consists in the fact that it is provided to insert in the channel, in transmission, information on the movement of the image, and the use of such information, by way of the receiver, for improving the characteristics of the image.
摘要:
The present invention refers to a method of data transmission for telemetry, applicable with distribution systems, in particular of gas, water, electric energy, heat, that provides a central station and a plurality of peripheral stations connected with said central station; the main characteristic of the invention consists in that a plurality of intermediate fixed stations are provided, each connected in a permanent manner with the central station and, via radio, with a plurality of peripheral stations.
摘要:
The present invention refers to an improved electronic enlarger for the purblind, comprising a telecamera for filming an image and a display device for displaying it; the main characteristic of the invention consists in that said display device is equipped with switching means and is able to display upon choice the image filmed by the telecamera in black and white, or in the colour green, or in the colour amber.
