Abstract: A frothing device including a central body which is detachably associable with a steam delivery tube and an outer casing which fits over the central body. The central body forms channels for the passage of air and of liquid to be frothed, in order to mix them with the steam and consequently mix the three flows. The device further includes a first mixing region for forming a mixture composed of the air and the liquid to be frothed, which arrive respectively from an air intake channel and a liquid rising channel, which are formed by the central body and by the outer casing, the formed mixture then converges in a second mixing region with the steam that is injected in the second mixing region and arrives from the delivery tube and then enters the beverage by means of a discharge channel that extends from the second mixing region.

Abstract: A mixing, heating and/or frothing and/or whipping device for preparing hot milk-based beverages, comprising a central body which is detachably associable with a steam delivery tube and an outer casing which fits over the central body; the central body protrudes partially from the outer casing in order to immerse it partially in a beverage together with part of the outer casing and forms channels for the passage of air and of liquid to be frothed, in order to mix them with the steam and consequently mix the three flows, the device further comprising at least one first mixing region for forming a mixture composed of the air and the liquid to be whipped, which arrive respectively from at least one intake channel and at least one rising channel, which are formed by the central body and by the outer casing, the formed mixture then converges in at least one second mixing region with the steam that is injected in the second mixing region and arrives from the delivery tube and then enters the beverage by means of at

Abstract: The energy supply system comprises at least one protected solar module with at least one photovoltaic cell and a local control unit connected to a switching module, which is controllable in such a way that the transfer of electrical energy from the photovoltaic cell via first and second wires of a power line to a load is interruptable in the event that a verification procedure that can be performed by the local control unit has provided a negative result. According to the present invention a chip-card with an electronic module is provided for each or for a plurality of solar modules comprising a first access code that corresponds to a second access code stored in a memory unit, and that a card-reader is provided.

Abstract: An apparatus for obtaining beverages by infusion comprises an indicating device arranged for indicating that a preset infusion time interval has passed; a method for obtaining beverages by infusion comprises imbibing with water at a desired temperature a dose of a substance or of a mixture of substances from which beverages have to be obtained, and indicating the duration of the infusion through a suitable indicating device indicating that a preset infusion time interval has passed; a timing device is provided with a hooking element arranged for hooking said timing device to an apparatus for preparing beverages by infusion.
