Abstract: The invention relates to a method of implementing a shielded multiconductor cable to the tracks of a printed circuit. The conductors have end portions stripped and positioned. A first strip is put into place. Then each conductor core and a portion of its shielding are stripped. The stripped ends are put into position and then fixed to a second strip that is connected to the first strip by arms. The assembly is then fixed to the printed circuit by soldering the stripped ends to the conductor tracks and by soldering the stripped portions of shielding to the shielding connection track.

Abstract: The invention relates to a method of continuously manufacturing a conductor having a core S based on aluminum and coated by being electroplated with at least one layer of silver, characterized in that the following steps are performed in succession with intermediate rinsing steps (r):a) the conductor is degreased;b) oxide is removed from the conductor;c) the surface of the conductor is treated in an adhesion bath;d) a first layer of silver is electroplated by immersion in a first electrolytic bath; ande) a second layer of silver is electroplated by immersion in a second electrolytic bath.

Abstract: Process for continuous manufacture of an electrical conductor consisting of an at least partially aluminium-based central core coated by continuous electrodeposition with at least one metal layer, including pretreatment of the surface of the core, characterized in that the following are subsequently performed successively on the core,a) an electrochemical deposition of copper in an aqueous bath maintained at a temperature of between 20.degree. C. and 60.degree. C., containing KCN, CuCN, K.sub.2 CO.sub.3 and KNaC.sub.4 H.sub.4 O.sub.6 with a current intensity of between 1 and 10 A/dm.sup.2 ;b) rinsing at ambient temperature;c) an electrochemical deposition of tin in an aqueous bath maintained at a temperature of between 20.degree. C. and 60.degree. C., containing essentially tin dissolved in methanesulphonic acid and, optionally, additives, with a current intensity of between 1 and 100 A/dm.sup.2 ;d) rinsing with water at 60.degree. C.

Abstract: A method of manufacturing a PTFE tape whose density is less than or equal to 0.3 g/cm.sup.3, the method being characterized in that a raw PTFE tape is subjected to a first step of stretching while being heated so as to reduce its density to within the range 0.7 g/cm.sup.3 to 0.30 g/cm.sup.3, after which at least one step is performed of the type including a stage during which the tape is stabilized without changing the state of the PTFE by being passed through an oven at a temperature and for a duration that are functions of the mass to be stabilized while keeping the tape under tension so that its density does not increase, followed by a stage of stretching under heating so that the density of the tape reaches a value lying in the range 0.2 g/cm.sup.3 to 0.12 g/cm.sup.3.

Abstract: Insulating coatings are disclosed which include an inner layer of glass fabric impregnated with a binding agent supporting particles of mica, followed by two additional layers, of either polytetrafluoroethylene or glass fabric, which readily adhere to each other. The polytetrafluoroethylene decomposes at temperatures of about 1,000.degree. C., at which temperatures the glass fabric melts to convert the coating into a glass coated mica which can maintain its insulating properties both at those high temperatures and upon cooling to lower temperatures.
