Abstract: A machine for dispensing hot beverages, e.g. coffee, comprising a liquid heater, in particular for heating water intended for human consumption, provided with a container, adapted to be at least partially filled with a first liquid to be heated, and a heating electric resistor arranged outside the container, in contact with the bottom of said container, so as to indirectly heat said first liquid through said bottom.

Abstract: An electric radiant hotplate includes a base of electrically insulating material and a peripheral crown extending along the outer rim of the base and projecting upwards. A strip of resistive material is inserted in the base and is formed by a sequence of planar lengths and curved lengths connected to respective planar appendices that are inserted in the insulating base. The appendices can be connected to the planar lengths by respective peduncles applied on to the same side edge of the flat strip of resistive material. The appendices can also be either coplanar or not coplanar to the planar lengths and include a first portion connected to the respective planar length of the strip, and at least a second planar portion that is not coplanar with the first portion and is joined to the first portion via a rectilinear border, the first portions being applied on a same side edge of the flat strip of resistive material.

Abstract: Electric radiant hotplate, suitable also for use in cooking tops, comprising: a base of electrically insulating material, a peripheral crown extending along the outer rim of said base and projecting upwards, at least a strip or resistive material that is inserted in said base dand is formed by a sequence of planar lengths and curved lengths are connected to respective planar appendices that are inserted in the insulating base. In one embodiment, said appendices are connected to the planar lengths by means of respective peduncles applied on to the same side edge of the flat strip of resistive material.

Abstract: Conduit for conveying and heating a flow of gas, comprising in its interior at least an electric heating element formed by a thick-film layer, in which said electric heating element works as a positive temperature coefficient (PTC) element and is arranged peripherally in relation to the gas flow cross-section of the conduit, i.e. is oriented in a substantially parallel manner to the flow direction of said gas, so that the latter is not even partially obstructed by such a thick-film layer. In a preferred manner, this heating element is subdivided into a plurality of individual and distinct heating elements arranged in parallel and energized in a successive and cumulative manner so that the initial power input can be maintained within pre-established limits, while the power input under steady-state conditions is reduced to a quite lower value, which is however still sufficiently high as to ensure an acceptable power output level.

Abstract: A connection flange for an armored resistance element, particularly for electric ovens, has a plate provided with a plurality of holes for insertion of end portions of the armored resistance element. Minor edges of the plate are extended into at least two profiled flat fins with their sides diverging outwards. The fins are formed during actual stamping of the plate and then are bent at 90° to be inserted into corresponding slots provided in the edges of the oven, after which they are twisted to prevent their withdrawal.
