Abstract: A system for assembly between a sheet of glass including a countersunk hole on each of its sides and another sheet of glass also including a countersunk hole on each of its sides, each countersunk hole being designed respectively to take first and second connecting pieces, each of the first and second connecting pieces being provided with a bore. The system also includes a connecting core connecting with the first and second connecting pieces. The core includes first and second parts. The first part of the core mates with the surface of the bore of the first connecting piece on which it exerts a force roughly parallel to the axis of the hole and the second part of the core fits into the bore made in the second connecting piece therein to react to the force.

Abstract: Building materials based on polyisocyanate-impregnated lignocellulosic substrates provide increased strength and water, fire, insect, and fungi resistance compared to prior art building materials. At the same time, such building materials exhibit an aesthetically pleasing surface and can, therefore, be used in consumer visible applications (such as furniture) as well as in consumer invisible (such as door frames and stiles) applications.

Abstract: A method for exchanging, in real time, information between several persons provided with a mobile telephone adapted to be connected to a server. The method includes, for a user, transmitting to the server an identification signal, displaying on a screen of a first mobile telephone a list of persons having transmitted the identification signal, selecting from the list persons with whom the user wishes to exchange information, transmitting to the server a request for being connected to selected person, and interconnecting the first mobile telephone with the mobile telephones of the selected persons. Thus the interconnected persons can exchange information data in real time.

Abstract: Polyester films which are self-adhesive under pressure are provided, said films having, on one face thereof, an adhesive layer which comprises a copolymer of vinyl acetate and a maleate ester of an aliphatic alcohol having 4 to 10 carbon atoms. These films have the advantage that they can be rolled up and then unrolled without the adhesive layer becoming detached.
