The present invention relates to an automated disinfection apparatus for immersible endoscopes, fibrescopes and their accessories. It consists of an upper chamber (2), a sheath (3), which are connected by a sleeve (1) which, in alternate operation, seals the sheath, allowing alternate flow of products through the channels of the endoscope or outside the latter. The apparatus is equipped with a pis...

The assembly has a first, hollow shaft (12) that telescopically receives an axially aligned second shaft (28) so as to permit the effective length of the assembly to be altered within a limited range. The two shafts are rotatable relative to one another and the opposite ends of the shafts have U-joints (14,38) attached to them, with a compression clamp (46) enabling the two shafts to be locked rel...

Cement for use in works exposed to organic acids and resistant to these acids, contains a sulpho-aluminous clinker, or a ferro-aluminous clinker, or a mixture of these.

The smart card has a flexible support (10) carrying an integrated circuit (13) to deliver identification data, and an interface (16), to transmit the data, at the surface of the card. The support is formed from a thin film (12) with a microcircuit (13) fixed to the film. A layer (14) of a polymerized material provides localized stiffening of the card in the region of the contacts.

L'invention concerne une carte à mémoire du type sans contact, comportant un corps de carte laminé en matière plastique (1) incluant une feuille de support (1. 2) sur laquelle est agencée une antenne de couplage (5) ainsi qu'un circuit intégré (7) relié à ladite antenne.Conformément à l'invention, le circuit intégré (7) repose directement par deux plots de contact sur deux plages conductrices (...

The container is made up of two compartments (2, 3), each holding one of the two ingredients (A, B) to be mixed together. One of the compartments holds an effervescent compound (10) which releases a propellant gas which allows the mixture to be discharged through a valve (7) and a spray nozzle (8). The effervescent compound comprises at least one reagent, partly or entirely enclosed in a material ...

The knee joint prosthesis has two longitudinal ribs (6,7) defining the edges of the contact face (5) of the tibial plate (2). The ribs are angled in cross section to form a trapezoidal section groove (11). The joint pad (4) is selected from a range of sizes to fit into the groove.;

Cette prothèse comprend un plateau tibial métallique (2), un élément condylien métallique (3) et un patin (4) en m...
