Abstract: A system includes a plurality of roofing shingles installed on a roof deck. Each of the roofing shingles includes first and second ends, first and second edges, a head lap, a reveal portion, a first side lap at the first end, and a second side lap at the second end. The second side lap includes a first surface, which has an adhesive. The first side lap of a first one of the roofing shingles overlays and is attached to the second side lap of a second one of the roofing shingles to form a sealed portion between the head lap of the first one of the roofing shingles and the head lap of the second one of the roofing shingles.

Abstract: The invention relates to a Composition comprising or consisting essentially of a product according to formula (I): LiaPSbXc (I) wherein—X represents at least one halogen element; —a represents a number from 2.0 to 7.0; —b represents a number from 3.5 to 6.0; and—c represents a number from 0 to 3.0; in the form of particles or articles the size of which being such that less than 10 wt % of the composition pass through a sieve of 200 ?m.

Abstract: A static metal seal comprising an outer sealing layer, wherein the outer sealing layer comprises a textured surface that is configured to come into contact with the surfaces that are to be sealed, the textured surface comprising a network of depressions spaced apart from one another on the textured surface, wherein the depressions are blind, do not pass all the way through the outer sealing layer, and do not communicate with one another.

Abstract: A method for producing a welded steel blank (1) includes providing two precoated sheets (2), each comprising a steel substrate (3) having a precoating (5) on each of its two main faces (4), each sheet (2) comprising, on each main face (4), at a weld edge (14), a removal zone (18) in which the precoating (5) is removed over a removal fraction; and butt welding the sheets (2) using a filler wire (20) so as to create a weld joint (22) having an aluminum content AlWJ comprised between 0.1 wt. % and 1.2 wt. %. The composition of the wire (20) and the proportion of wire (20) added is such that the weld joint (22) has: (a) a quenching factor FTWJ such that FTWJ?0.96FTBM?0, (b) a nickel content NiWJ?14?3.4×AlWJ and a chromium content CrWJ?5?2×AlWJ, where AlWJ is the aluminum content of the weld joint (22).

Abstract: A static metal seal comprising an outer sealing layer, wherein the outer sealing layer comprises a textured surface that is configured to come into contact with the surfaces that are to be sealed, the textured surface comprising a network of depressions spaced apart from one another on the textured surface, wherein the depressions are blind, do not pass all the way through the outer sealing layer, and do not communicate with one another.

Abstract: The invention relates to a method for the anti-corrosion processing of a part that comprises the step of spray deposition of a zirconium and/or zirconium alloy layer onto the surface thereof.
