Abstract: The electronic component, comprises an integrated circuit incorporating several separate functional blocks within a semiconductor substrate, and electrostatic discharge protection means. These electrostatic discharge protection means comprise several separate metal discharge rails (GNDi) placed above the substrate (SB) and respectively associated with the plurality of functional blocks (CRi), all these metal discharge rails being mutually unconnected electrically within the integrated circuit (CI) but connected electrically via an electrical connection (FLi) external to the integrated circuit to one and the same ground plane (SLG) forming a ground reference for the electrostatic discharges, this ground plane (SLG) being located outside the integrated circuit (CI), and possibly being a heat slug.

Abstract: This invention relates to a device for organizing access to a bus connecting a memory to at least two entities asynchronous binary signals representing requests for access to the bus. The device supplies binary signals to authorize the access to an entity based on a priority determination between the different requests and includes a priority decoder in wired logic associated with an input register. A loading of the state of the access request signals happens, if an access request is present while a read or write cycle of the memory is executed, upon the arrival of a pulse on a signal issued by a memory controller associated with the memory and indicative of the end of a memory cycle.

Abstract: A device for transferring binary data between a time-division multiplex and a RAM includes circuitry for assigning, for each time slot of the multiplex, a logical channel number. This enables two HDLC controllers, respectively for transmission and reception, to be shared between all the channels of the multiplex.

Abstract: According to the invention, the treatment process for imparting flame retardancy consists in grafting a textile material containing nitrogen atoms in its polymeric structure, especially silk, with a phosphoric acid ethyenic ester of the general formula ##STR1## in which R.sub.1 is selected from the group comprising H and alkyls and R.sub.2 is selected from the group comprising alkylenes and alkylene oxides and/or polyalkylene oxides, for example phosphated ethylene glycol methacrylate, the grafting rate being less than or equal to 20%.

Abstract: A grafting reaction system comprises an activated polymer and a grafting medium containing a monomer, with the system containing free radicals. The system further comprises 0.1 to 2% by weight of the grafting medium and monomer of a homopolymerization inhibitor compound, the inhibitor compound comprising a compatabilizing function toward the grafting medium which is selected from the group consisting of sulfonic, carboxylic and phenolic groups, and an inhibiting function which acts as a transfer agent for the free radicals, the inhibiting function being an allyl-type unsaturated group. The inhibitor compound has a diffusing capacity through the grafting medium which is greater than its diffusing capacity through the polymer.

Abstract: According to the invention the material, in particular a textile, includes in its polymeric structure grafts forming complexes with at least one metal ion possessing recognized antiseptic activity. These grafts are formed by polymerization of unsaturated monomers with a complexing function, including the phosphate of ethylene glycol methacrylate or a polymerizable derivative of quinoline such as acryl 8-hydroxy quinoline. The process of preparation comprises a first step of grafting, for example by electronic irradiation of the material and impregnation with a bath of monomer, and a second step of impregnation of the grafted material with one or serveral baths containing the metal ion(s), such as copper, zinc, tin, mercury.

The device (4) further comprises:(a) a bottom plate (5) supporting the plane hydrophobic material,(b) at least one cavity (6) for the liquid medium to be tested, said cavity having an outlet orifice (9) situated above the plane hydrophobic material, and(c) scraping means (8) acting on the hydrophilic material (1) and capable of moving the liquid contained therein over the surface of the plane hydrophobic material (3).

Abstract: The invention consists in making an emulsion of a fluorinated product, in the presence of a derivative of morpholine. The derivative of morpholine may be the morpholine itself, a saturated derivative or a non-saturated derivative, for example morpholinoethyl methacrylate. The fluorinated product may be a fluorinated monomer, for example 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl methacrylate. Placing in emulsion is effected by adding to the fluorinated product the derivative of morpholine in the presence of a surface-active agent, and by adjusting, with mechanical stirring, the desired quantity of liquid.

Abstract: The grafting reaction according to the invention occurs after having impregnated the polymeric material, on which were previously created free radicals by activation within an emulsion containing the fluorinated monomer and a graftable derivative of the morpholine. The preferred reagents are morpholinoethyl methacrylate and 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl methacrylate. The invention is applicable to the waterproofing of textile articles, particularly made of cotton, silk, linen. The material thus grafted is waterproof when cold, but when hot, it may be washed, dyed or printed by transfer.

The process comprises applying to the glass substrates a solution comprising a silane having a double ethylene bond, contacting the products thus coated with an atmosphere formed by a mixture of ozone and oxygen, and placing these coated products in contact with an unsaturated organic monomer. The monomer may be added in the form of a solution, an emulsion or a suspension. The products thus obtained may have a number of technical applications.
