Abstract: Multi-function combined brush (1) for vacuum cleaner. A brush (1) for vacuum cleaner of a “combined” type, i.e. a brush (1) capable of changing the operating mode without being obliged to replace the accessory, whose main feature consists of its possibility of alternating its functions, for instance carpets, floors, and liquids, by way of a pedal (7) featuring one static position. Very advantageously, the innovative solution according to the present application makes it possible to embody a combined brush (1) capable of performing different functions in one device.

Abstract: A telescopic extension device for cleaning systems comprising at least one first external tubular assembly and one second internal tubular assembly slidingly coupled with each other so as to vary its own extension. Each tubular assembly comprises two channels for the passage of the fluid streams produced by a vacuum cleaner also capable of producing steam. In a preferred embodiment, the duct featuring the greater diameter is used to suck the air and the particles of dirt whereas the other duct makes steam flow outward.

Abstract: Solar panel tube, comprising a first pipe (11); a second pipe (12); a first insulating material (13) surrounding said first pipe; a second insulating material (14) surrounding said second pipe; said first insulating material comprising a supporting layer treated with aerogel; said second insulating material comprising a supporting layer treated with aerogel; wherein said first and second insulating materials (13, 14) are wrapped in a nylon thread winding (20) and said first and second insulating material are further wrapped by a protective layer (15).

Abstract: A vacuum cleaner brush with a flexible internal suction pipe (100), in plastic material and items in plastic or steel, intended for application to all types of domestic or for community vacuum cleaners, fitted with a single articulated joint or with a double articulated joint compared with two axes (136, 144), parallel to the ground, fitted in centre line with a flexible pipe (120) rigidly connected to the central connection (116) of the suction split (112) on one side and on the other, to the rigid pipe (132) of the upper and main articulated joint (142), between which a connection (146) is inserted, with the possibility of oscillation-rotation, second (150), without however allowing the retraction ram with an axial retaining ring also placed between them (148), producing a continuity without possibility of any loss in the joins for the pipe (120).

Abstract: Shoe with detachable sole and vamp, in which: the sole (1) has an upper surface (2) on which several tubular elements (4) are applied spaced from each other by a preset value; the vamp (7) has a lower surface (6) on which there are applied several tubular elements (8) spaced from each other by a preset value; the vamp (7) can be positioned onto the sole (1) by positioning said lower surface (6) of the vamp (7) onto the upper surface (2) of the sole (1) with the insertion of the tubular elements (8) of the vamp (7) between the tubular elements (4) of the sole (1); and the vamp (7) is detachably anchored to the sole (1) by inserting a wire (9) through the said tubular elements of the sole and the vamp after positioning of the vamp onto the sole. Said tubular elements of the sole (1) are placed according an open annular path, with two tubular elements (40, 41) disposed in correspondence of a respective end of the open annular path and communicating with the outside of the sole (1).

Abstract: Shoe with a separable sole and upper, wherein the sole (1) features an upper surface (2) on which a plurality of tubular elements (4) are applied so as to be distanced from one another with a predetermined value, wherein the upper (7) features a lower surface (6) on which a plurality of tubular elements (8) are applied so as to be distanced from one another with a predetermined value, wherein the upper (7) is associable to the sole (1) by positioning the lower surface (6) of upper (7) on the upper surface (2) of sole (1) and by inserting the tubular elements (8) of upper (7) among the tubular elements (4) of sole (1), wherein the upper (7) is reversibly anchored to the sole (1) by passing a thread (9) into the tubular elements of the sole and of the upper after positioning said upper on the sole, characterized in that said tubular elements applied on sole (1) are positioned in an open annular disposition with two tubular elements (40,41) each positioned in correspondence of a respective end of said open annul

Abstract: Method for correction of the spark advance for an internal combustion engine with a continuous phase transformer at the intake and/or exhaust; for each cylinder, the method consists of calculating a theoretical value of the optimum spark advance according to the drive point, calculating a first correction value, which depends on the mass of burnt gas-trapped in the cylinder at the end of the intake phase, calculating a second correction value, which depends on the torque value generated, and calculating the actual value of the spark advance, by adding the two correction values to the theoretical value of the spark advance.
