Abstract: Pour la reconnaissance de caractère en code CMC-7, une tête de lecture (12) fournit un signal analogique à deux discriminateurs de niveau (SEb et SEh) à seuils différents. Deux chaines de traitement (REb et REh) reçoivent chacune le signal d'un des deux discriminateurs de niveau et délivrent des signaux représentatifs des intervalles courts ou longs du caractère codé. Un multiplexeur (MX) permet de choisir l'un ou l'autre des groupes de sortie des deux chaînes de traitement, en fonction de l'état de deux circuits de détection d'erreur (ERb er ERh). En l'absence d'erreur, le multiplexeur choisit la chaîne de traitement reliée au discriminateur de niveau au seuil le plus bas (SEb). En cas d'erreur, le signal de l'autre chaîne est transmis par le multiplexeur. Extension à un dispositif à deux têtes de lectures avec quatre chaînes de traitement.

Abstract: A method of providing a substrate with a layer of a tertiary compound comprising silicon, silicon carbide and a transition series metal. In accordance with the method, a substrate having at least a surface layerthereon of a transition series metal is coated with silicon carbide particles having an average particle diameter in the range of up to about two microns. The coated substrate is then heated in an inert atmosphere to a temperature between 1000 and 1300°C for sufficient time to allow diffusion to occur between the silicon carbide and the transition series metal layer, thereby forming the tertiary compound. Substrates coated with the tertiary compound are particularly suitable for preparation of alkali metal/polysulfide batteries wherein the substrate may be exposed to corrosive attack by molten polysulfide salts.

Title: Apparatus for severing a fibe layer of staple fibres.
Inventor: GYGER PAUL
IPC: D01G27/04
Filed: 1981-01-26
Abstract: Plant for separating an aggregate of fibers comprised of agglomerations which may slide with respect to each other, by means of two pairs of driven rollers (9/10; 11/12), which form two pinching lines (m and n) for the agglomeration. The separation is effected because the two pairs of rollers are coupled kinematically by a flexible force transmission element (19) so that the displacement of a roller tandem (26) positionned in the path of the element (19) causes the relative rotation of one pair of rollers (11, 12) with respect to the other pair (9, 10). The aggregate pinched between the pinching lines m and n will be separated by said relative rotation of the pairs of rollers. This plant has the advantages to be simple and reliable and further it does not require any clutching means.
