Abstract: A bicycle frame comprising a saddle tube (1) connected to a single upper bar (3) and a single lower bar (4), said bars each having a front end carrying a head tube (2), said frame further comprising a strut (5) and a base (6) each having a rear end that carries a means (7) of association to respectively one side of a rear wheel of said bicycle, said strut—respectively said base—being formed in a single tube (8, 9) with the upper bar (3)—respectively lower (4) bar—, said upper (8) and lower (9) tubes being associated respectively with one side of the saddle tube (1) by extending continuously on either side of said saddle tube.

Abstract: A shielding screen for a printed circuit board that supports an electronic circuit has a frame and at least one cover for covering the frame. The frame and the at least one cover, when adhesively fastened to each other, form a subassembly that, when attached to the printed circuit board, electromagnetically shields the electronic circuit. For adhesively fastening the at least one cover to the frame, a conductive adhesive substance is applied to opposite surfaces of the frame and the at least one cover.

Abstract: The invention discloses an electromagnetic shielding screen for a printed circuit board or any other similar support of an electronic circuit. This shielding includes a band and one or various separate compartments, each having a cover whose form corresponds to that of the associated compartment, and the outside dimensions of each cover correspond at least to the inside dimensions of the associated compartment for forcibly fastening each cover in its associated compartment.

Abstract: This electrical apparatus comprising a removable accumulation device (10) coupled to a photovoltaic cell device (20) has a front. The light-sensitive face of the photovoltaic cell device (20) is oriented to the same side as said front.
