Abstract: This invention relates to a method for molding a sleeve-type reinforced plastic tubular body, such as a pipe coupling, and to a mold therefor. According to the method of this invention, a sleeve-fitted reinforced plastic tubular body is produced by using a mold obtained by assembling a main body and sleeve-molding members fixable and axially slidable to and along the outside surface of the main body. Accordingly, by providing sleeve molding members of different configurations and sizes and using them exchangeably according to the configuration and size of the desired molded article, tubular bodies having a sleeve of different configurations and sizes can be molded as required. Furthermore by adjusting the fixing position of the sleeve-molding member with regard to the main body of the mold, tubular bodies having a tubular section of different lengths can be produced by using one type of mold.

Abstract: La présente invention concerne les dispositifs de compression et les dispositifs de décompression temporelle de données. Le dispositif de compression met en oeuvre deux signaux d'horloge H n  et Hp dont les fréquences F n  et Fp correspondent respectivement aux rythmes des données du signal "à comprimer" et du signal "comprimé". Il permet, au début de chaque période de compression d'un paquet de données, de synchroniser ces deux signaux d'horloge quelle que soit, pour un taux de compression fixe, la durée des paquets de données. Pour cela, le dispositif comporte un multiplexeur (4) recevant p signaux d'horloge auxiliaires (p entier positif) de même fréquence Fp, mais déphasés, et des moyens (5) pour commander le multiplexeur (4) pour qu'il délivre celui des signaux d'horloge auxiliaires qui est en phase avec le signal d'horloge H n .

Abstract: Un circuit synthetiseur de tonalites (10) comprend une resistance a multi-branchements (86) produisant une pluralite de tensions separees aux branchements (T1-T16). Un commutateur (88-118) est prevu pour chacun des branchements (T1-T16). Les commutateurs de branchements (88-118) sont organises en quatre groupes. Un deuxieme groupe de commutateurs est organise en deux groupes et chacun des commutateurs du deuxieme groupe est connecte a l'un des commutateurs dans chacun des premiers groupes. Les commutateurs d'un troisieme groupe (164-170) sont chacun connectes a l'un des commutateurs du deuxieme groupe (132-138). Les circuits sensibles a un signal numerique d'entree d'horloge produisent un groupe de signaux de commande sur des lignes de commande (66-72) qui sont connectees respectivement pour actionner chacun des quatre groupes des premiers commutateurs (88-108). D'autres circuits sensibles au signal numerique d'entree transmettent des signaux de commande au travers des lignes de commande (74, 76) pour actionner le deuxieme groupe de commutateurs (132-138). Un autre circuit fonctionne en reponse au signal numerique d'entree pour produire des signaux de commande sur des lignes de commande (78, 80) pour actionner le troisieme groupe de commutateurs (164, 170). Le premier, le deuxieme et le troisieme groupes de commutateurs sont actionnes de maniere telle qu'un terminal de sortie (168) est connecte de maniere sequentielle a chacun des branchements (T1-T16) de la resistance (86). Les connexions de branchements sont etalonnees et selectionnees dans un ordre permettant de produire un signal sinusoidal de sortie au terminal de sortie (168).

Abstract: Un système (10) permet de déterminer l'épaisseur d'un matériau de revêtement conducteur à flux magnétique sur un matériau de base conducteur à flux magnétique de perméabilité différente, et consiste à appliquer une tension alternative (96) à l'enroulement primaire (52) d'un transformateur du type à noyau incomplet (54). Le rapport entre la tension de l'enroulement secondaire (40) et la tension de l'enroulement primaire (52) est déterminée avec le matériau dont on mesure (56) l'épaisseur de revêtement et complétant le noyau incomplet (54). Le rapport des tensions est une mesure non-destructive de l'épaisseur (64) du matériau de revêtement. Le mode préférentiel de réalisation applique une tension constante d'une source à courant continu (18) à l'enroulement primaire (52). Ceci élimine le besoin de déterminer le rapport des tensions. La tension de l'enroulement secondaire (40) est une mesure directe non-destructive de l'épaisseur (64) du matériau de revêtement. En référence à un graphe particulier matériau de revêtement-matériau de base, l'épaisseur du revêtement est lue à partir de l'échelle adjacente à l'intersection de la tension induite dans l'enroulement secondaire (40) et de la courbe (78, 80, 82, 84, 86, 88, 90, 92, 94) représentant la composition du matériau de revêtement.
