Title: Improvement of the biocompatibility of solid surfaces.
Inventor: GUIRE PATRICK E
IPC: A61L27/54
Filed: 1987-10-16
Abstract: The biocompatibility of biomaterials having solid surfaces is improved through coating the same with biocompatible agents. The method for modifying the solid surface to improve biocompatibility employs molecules of a biocompatible agent and a chemical linking moiety possessing a photochemically reactive group capable upon activation of covalently bonding to the solid surface and possessing a different reactive group as capable upon activation of covalently bonding to separate molecules of the biocompatible agent. One of the groups is unresponsive to activation by a stimulus to which the other group is responsive. The method comprises applying stimulus to sequentially activate the groups and covalently bind the different reactive group of the linking moiety to the molecules of the biocompatible agent and to photochemically covalently bind the linking moiety to the solid surface with a sufficient population density to enable the molecules of the biocompatible agent to effectively shield the solid surface and to provide a biocompatible surface.

Abstract: Dans un rotor centrifuge, une coulisse annulaire (5) expose un de ses côtés en direction d'une chambre de séparation (7) et son côté opposé en direction d'une chambre annulaire (9). La coulisse (5) peut être déplacée axialement par le déplacement radial de la surface de liquide libre des corps liquides dans lesdites chambres (7, 9). Selon la présente invention, on effectue un déplacement radial d'une surface de liquide libre dans ladite chambre annulaire (9) sans déplacer de liquide de cette dernière. On utilise à la place une coulisse additionnelle mobile (6) qui présente une surface orientée axialement exposée dans la chambre annulaire (9). La coulisse additionnelle permet de déplacer du liquide dans la chambre annulaire (9) radialement vers l'extérieur et vers l'intérieur.

Abstract: The patent describes an optical sensor for measuring the position of a remote moving body, which converts said position into a phase modulation of an optical measure signal and in which the false phase variat­ions induced by the variations in the environmental conditions are compensated. 
The compensation is effected by generating an optic­al reference signal, which travels together with the optical measure signal, and by making a phase comparation between the two signals.
