Abstract: Device for fixing a sensor (2) to a tire (5), which device comprises at least one base (1) provided with a seat (1a) adapted to house at least partially a first portion of at least one sensor (2) for tires, and at least one cover (3) adapted to house at least partially a second portion of the sensor (2), wherein the cover (3) comprises at least one seat (3a) adapted to house at least partially the base (1), wherein the base (1) comprises at least one first portion (1b) which is arranged adjacent to the seat (1a) of the base (1) and at least one second portion (1c) which at least partially surrounds the seat (1a) of the base (1), wherein the cover (3) comprises at least one first portion (3b) which is adapted to at least partially surround the seat (3a) of the cover (3) and at least one second portion (3c) which is adapted to at least partially surround the second portion of the sensor (2), wherein the first portion (1b) of the base (1) comprises at least one support surface (1e) on one side of the base (1) op

Abstract: A tyre has a tread pattern comprising at least one circumferential sipe (10), having, in radial section, a profile comprising: a first zone (Z1) close to the radially outer surface (S), having side walls (11) mutually spaced apart according to a minimum width W1; a second zone (Z2), having a portion (Pt) in which the side walls (11) diverge from one another, and a portion of maximum width (Pmax) having a maximum section width W2; and a third zone (Z3) having a maximum width W3, less than W2, radially inner with respect to the second zone (Z2). In the third zone (Z3) the side walls (11) join with a bottom portion (Pf) defining a total depth (H10) of the sipe (10). The ratio between W2 and W1 is greater than 1 and equal to or less than 2. A geometric centre (G2) of the portion of maximum width (Pmax) lies at a depth (PG) comprised between 40% and 60% of the total depth (H10).

Abstract: The water heater (2) or steam generator comprises a chamber (4) in two sections (5, 6) formed in particular by stamping. Inside this chamber a heating element (8) is arranged, which has a spiral-shaped main section (10) and two end sections (11, 12) passing through two circular openings of the chamber. The two end sections are welded to the chamber by a laser beam such that the weld obtained is continuous and ensures a good mechanical fixture of the heating element and an adequate tightness for the water heater or steam generator. For this purpose, a flange (18) is arranged at the periphery of each opening. Moreover, the two sections of the chamber have a widened edge (28) to allow them to be welded effectively.
