The first raised elements (8) have an extended shape according to their main direction of extension. The forming step involves making one or more higher second raised elements (9).

Abstract: The invention consists of a tab (1), projecting from a plate (2) equipped with an elongated stiffener (11) placed just next to the point in which the tab projects from the body of the plate and a drawn hole (14) or a deformity obtained by stretching and compressing/flattening (20,21) since there is a protective insulating coat on the plate (25); this hole or deformity is placed at the free end of the tab (1 producing the uncoated surface for the electrical contact.

Abstract: The object of the invention consists of a process through which containing metal structures are built and shaped, in one case using steel sheets pre-protected by paints, and made to be electrically conductive by adding aluminium powder, or other equivalent conductive metals having a fusion temperature which is equivalent to the one fusing the sheets to be welded, and whose boiling temperature is higher than their fusion one; in a second case using sheets pre-protected by a thin layer of zinc plating followed by an external film of acrylic resin; it also consists in resorting to the aid of anthropomorphic welding robots, at the end of whose mobile arm is placed the laser beam out put unit connected to the laser source by an optical fibre cable, and also in the fact that the welding is carried out on the internal not visible sides of the containing structures that are being built.

Abstract: The invention consists of a process to form low stretch-deep draws on metal sheet; it foresees an initial stage through which a sequence of thread-like cuts (2) are carried out on the metal sheet (1) corresponding to the surface that will be drawn, whose cuts (2) on the adjacent lines are offset compared with each other, a stage in which the metal sheet (1) is stretched, through which stage the opening of the cuts (2) is obtained, therefore an ample widening of the cut surface and a minimum stretching of the non cut surface and of the oblique stripped metal network, separating the empty spaces (3) obtained through the widening of the thread like cuts (2), and where necessary, a stage in which the metal sheet is bent along a line which allows, on the overlapped surfaces, the open spaces of one surface to correspond to the strips on the other surface in order to reduce or close the width of the spaces in order to reduce electromagnetic interferences.

Abstract: A tab (2) obtained from plate (1) from which it emerges through a process which includes a first shearing phase, with which the elongated vent hole (6) is carried out, a second coining phase with which the impression (4) and the protruding contact button (5) are obtained around the elongated vent hole (6), a second shearing phase with which the work hardened--reduced thickness metal is cut along the line which defines the tab (2) which is inflected and made to protrude from the surface (9) of the plate (1) on the side of the impression (4). On the three sheared off sides, the tab (2) is smaller than the impression (4) to allow it to deflect freely in the said impression (4) when it is undergoing stress.

Abstract: This invention is a spring-loaded door-closing device consisting of a section (1) having a longitudinal cavity (2) in the lower part which houses and allows a moving tube (15) attached to a pressure hook (16) and a reaction spring (18) to slide within. In the upper part of the section there are one or more longitudinal channels (5, 6), and one or more brackets (13) equipped with a structure for moving along, and fixing to, the channels (5, 6). The brackets have components for fixing them to the under part of a vehicle floor in such a position where they can hold open, when activated, the vehicle door, or doors.
