Patent FR-2569750-A1 (FR)
Title: Method for converting a truss intended for increasing the height of a building without modifying the slope of the roof and beam capable of supporting the newly created floor
IPC: E04G23/02
Filed: 1984-08-31
Abstract: This structural system makes it possible to raise part of the roof by moving the ridge line upwards on one or two roofing panels, so as to create, inside, habitable rooms with sufficient headroom, receiving light through vertical windows, opening over the remainder of the roof preserved on one, two or three facades. This method preserves the slopes and style of the house. It may be employed in a housing estate and even on houses placed side by side. It is of most value for houses in which the truss rests exclusively on the external walls without internal load-bearers. The modification of the roofing may be varied, as may the extent of enlargement desired. The remainder of the roofing remains in its initial state. In addition, beam making it possible to economically create, in small "roof trusses", a load-bearing wall for thin wide floors.

Abstract: The invention relates to microcircuit cards, used for electronic transactions or other purposes, and concerns a process for mass producing electronic modules to be used in these cards and the modules obtained according to this process. According to the invention, there are fabricated, on the one hand, a metal grid with a plurality of openings into which there penetrate tongues attached to the frame of this grid and intended to form the modules' contact areas, and, on the other hand, pellets of plastics material which have a generally flat front face, a rear face in which there is a hollow and, between this hollow and the front face, windows so arranged that they can be positioned opposite the grid tongues. Then a pellet is attached by its front face to the tongues in each opening, an integrated circuit chip is bonded to the bottom of the hollow in each pellet in such a way that its rear face is directed towards the grid, the connecting terminals of the chip are connected by means of conductors to the tongues to which the pellet is attached, said conductors being seated in the hollow in the pellet and passing through the said windows, and the hollow and the windows are filled with an insulating, hardenable and adhesive material. There then remains only to detach the modules from the grid by cutting the tongues around each pellet.
