Abstract: Matériaux chirurgicaux absorbables autorenforcés et/ou implants et/ou parties et/ou éléments d'implants, qui peuvent être implantés dans des tissus vivants ou sur la surface de ces tissus pour, par exemple, réparer des tissus endommagés, pour joindres des tissus ou des parties de tissus entre elles, pour accroître des tissus ou parties de tissus, pour séparer des tissus ou parties de tissus les uns des autres ou de leur milieu environnant, et/ou pour insérer des matières entre des tissus ou parties de tissus et/ou les en extraire ou les y introduire. Les éléments de renforcement de ces matériaux autorenforcés et/ou implants ou parties et/ou éléments sont enroulés au moins en partie autour d'un axe qui pénètre dans l'implant. Ces implants présentent des propriétés de résistance supérieures et plus isotropes que ceux de l'état antérieur de l'art.

Abstract: On quantifie des fuites de soupapes en mesurant une variable proportionnelle à une caractéristique de transfert thermique de la paroi (30) du tuyau et en comparant les mesures effectuées à des donées (84) qui traduisent une relation quantitative entre un indice proportionnel à la caractéristique variable de transfert thermique et une plage de taux de fuites de soupapes possibles dans le cas de la soupape en question. Dans un mode de réalisation simple de l'invention, on effectue a priori une analyse hydraulique thermique de la soupape spécifique et des tubulures associées afin d'établir une base de données sur la température de la paroi du tuyau en aval de la soupape en tant que fonction de débit de vapeur. La température de la paroi est simplement mesurée et comparée à la base de données. Dans un autre mode de réalisation, un manchon (54) refroidi à l'air est installé autour du tuyau (48) en aval de la soupape (50) et un courant réglé d'air passe à travers l'espace annulaire (62) situé entre le tuyau et le manchon. L'augmentation de la température de l'air en écoulement est mesurée et utilisée pour calculer le débit de vapeur qui s'échappe à travers la soupape. Dans un autre mode de réalisation, on quantifie la fuite de la soupape en surveillant et en réglant la chaleur fournie à une section locale d'un tuyau horizontal (94) en amont de la soupape. La zone centrale (106) des dispositifs de chauffage (96) est ajustée de façon à faire monter la température du tuyau d'une certaine valeur au-dessus de la température de la vapeur et la puissance requise pour maintenir cette température est mesurée. La base de données fournit une relation quantitative entre cette puissance fournie et l'écoulement de vapeur à travers la soupape.

Title: Improved reaction systems and/or polymer compositions for contact with living body tissue.
Inventor: RITTER WOLFGANG
IPC: A61K6/884
Filed: 1990-11-19
Abstract: Described is the use of physiologically compatible tocopherols, in particular vitamin E, as inhibitors against premature initiation of polymerization in reaction systems, capable of radical-initiated polymerization, which are brought, before and/or after polymerization, in contact with, and in particular implanted in, living human or animal body tissue. The reaction systems, or the polymers formed by them, can be degradation-resistant. In a particularly important embodiment, however, appropriate compositions or moulded products are used which are broken down, in particular absorbed over a controlled period, by the living body. The invention also concerns surgical bonding agents suitable for bonding body tissue, these agents being based on a radical-activated adhesive component which is used mixed with a radical inhibitor. The bonding agents are characterized by the fact that the inhibitor, or the greater part of it, is vitamin E. The preferred compositions are those described, free of physiologically undesirable solvents and production-related solvent residues.

Abstract: The round combing cylinder possesses a rotating cylinder body (12), on which a round-comb segment (14) equipped with combing needles (13) is fastened. Guide strips (15) extending in the circumferential direction are arranged after the round-comb segment (14) on the cylinder body (12) on both sides. When the round-comb segment (14) leaves a combed-out fibre tuft (F), the side edges of the fibre tuft (F) are guided by the guide strips (15). The side edges therefore remain more compact and have fewer fibres projecting laterally. A more uniform worsted fleece (K) is then obtained as a result. <IMAGE>
