Abstract: The invention relates to a connector module (100) which is used for telephone transmissions, more particularly adapted to transmissions on ADSL subscriber lines. The module (100) comprises a housing (108) including two parallel rows—(R1) and (R2)—of contacts facing each other, whereby each of said contacts comprises a first terminal part (106) for connection to a conductor and an opposite second terminal part (107), two successive contacts of a same row defining a pair of contacts, wherein each of said second terminal parts (107) normally rests elastically against the second terminal part (107) opposite. The module (100) also comprises a detachable card (104) for electrical connection and lowpass filtering of signals transmitted between the second terminal parts of at least one pair of contacts of a row, i.e. first pair, and said second terminal parts of at least one pair of contacts on the other row, i.e.

Abstract: In a module for connecting and distributing optical fibers, intended for use in an optical distribution frame, the first end of each fiber is connected to a connecting socket and the second end of each fiber is connected to an optical distribution or transmission cable. The module includes an arm for guiding each fiber fixed by its first end to a support for a row of connecting sockets and connected by its second end to a cassette for coiling up each fiber. The cassette is articulated to the arm.

Abstract: The distribution frame and the method relate to a telecommunication installation in which optical fiber links are connected to connection members formed by sockets distributed on the front face of at least one distribution rack and in which jumpers provide the links between the connection members to which the links are individually connected. A robotized set of specialized tools is provided: to mount a plug on one end of a jumper reserve stored in coiled form; to position the plug in a connection member of a socket; to fit the jumper uncoiled from this member as far as another member; to adjust the length and to cut a section of uncoiled jumper; and to mount a plug on the end of the section and to position this plug in the other member.

Abstract: A process for metallizing a substrate part includes the following three steps: coating the part with a precursor composite material layer consisting of a polymer matrix doped with photoreducer material dielectric particles, irradiating the surface to be metallized of the substrate part with a light beam emitted by a laser, and immersing the irradiated part in an autocatalytic bath containing metal ions, with deposition of the latter in a layer on the irradiated surface. The dimension of the dielectric particles is less than or equal to 0.5 microns. The method is intended in particular for producing a metallized part including a substrate part consisting of a flexible film.

Abstract: The low crosstalk device for connecting a multipair cable includes, on a stripped end part of the cable, rear support means provided with channels for retaining insulated wires of the pairs, front support means for guiding the wires to be connected to contacts and an intermediate part in which the wires cross over. The channels are in lengthwise lateral communication with one another to define a passage in which all of the insulated wires are gripped tightly together in a layer, near the sheathed cable, and are advantageously provided in a block which is held in position relative to the front support means. Application: male RJ45 connectors, cross-connection connectors, terminal strips.

Abstract: The invention relates to a process for the preparation of aspartic: acid by decomposition of ammonium aspartate wherein a concentrated aqueous solution of ammonium aspartate is continuously introduced into a diluent in which water has a low solubility, which diluent is maintained at a temperature at which ammonium aspartate decomposes into aspartic acid and ammonia, and wherein the water and the formed ammonia are continuously removed. The invention also relates to a process for preparing polysuccinimide starting from fumaric acid or maleic acid and ammonia involving said process for preparing aspartic acid from ammonium aspartate.

Abstract: The modular cross-connect panel for cable lines of cabled networks comprises a support assembly defining a vertical front portion and a horizontal rear portion, together with female connectors retained on the front portion and connected to the lines of cables fixed on the rear portion. In the panel said support assembly comprises two separate rigid supports referred to as a "front" support and as a "rear" support, together with two assembly columns fixed to the front support and releasably holding the rear support. The panel is applicable to a distribution frame for use in operating cable networks.

Abstract: The invention provides a process for the preparation of aspartic acid via a fermentation process for the preparation of ammonia fumarate, wherein the pH of the fermentation broth is controlled by the addition of a calcium base to produce a calcium fumarate precipitate, characterized in that ammonium fumarate is produced by separating the precipitated calcium fumarate from the fermentation broth, and reacting the same with a reagent selected from ammonia, ammonium carbonate, ammonia in combination with CO.sub.2 and mixtures therefore, to form ammonium fumarate and a co-product selected from calcium carbonate and calcium hydroxide, wherein the energy of indirect neutralization of fumaric acid by ammonia serves as the driving force for the conversion of calcium fumarate to the desired ammonium fumarate product and for the regeneration of a calcium base reagent, and wherein diammonium fumarate is enzymatically converted to ammonium aspartate and acidulated to from aspartic acid.

Abstract: The invention concerns a disconnectable male connector for a communications network including connecting means between wires (43) corresponding to the lines of a communications cable (44) and the terminals of a female connector which are connected to the lines of the communications network when the male connector is inserted in the female connector and means (41) for locking the male connector to the female connector, wherein said connection means (46, 81, 100) and said locking means (41, 80) can separate if the cable (44) is pulled. Applications include the integrated services digital network.

Abstract: The process for the termination of electric cables (2) makes it possible, during the installation of the electric structure of a building, to prepare the final connection of each cable (2) by any random operator. Use is made of standardized cable termination means for provisionally storing the cable ends. The apparatus essentially comprises a block (1) within which is inserted, for each cable (2), a locking part (3) having a flexible tongue (5). The introduction of a cable (2) into its recess (7) is definitive as a result of the locking action of the tongue (5). The final connection takes place by means of a connecting hole (8) traversing the recess (7). It is therefore possible to prepare the connection of numerous cables with numerous electrical equipments to be supplied.
