Abstract: A method for hydrophilifying the surface of a substrate by taking advantage of photocatalytic action.      The substrate has a photocatalytic titanic coating (10).      The surface of the photocatalytic coating (10) bears the solid acid that increases a hydrogen bond component (.gamma.s h) in the surface energy in the solid/gas interface of the coating. Photoexcitation of the photocatalyst enhances the hydrogen bond component (.gamma.s h) in the surface energy of the photocatalytic coating (10), accelerating the physical adsorption of molecules of water in the atmosphere through a hydrogen bond (16) onto hydrogen atoms in a terminal OH group (12), bonded to a titanium atom, and a bridge OH group (14) on the surface of the coating. This results in the formation of a high density, physically adsorbed water layer (18) on the surface of the photocatalytic coating (10), thus permitting the surface of the substrate to be easily hydrophilified. The method is applicable to antifogging, antifouling, selfcleaning and cleaning of articles.

Title: Suture cartridge assembly for a surgical knot
Inventor: SCHULZE DALE R
IPC: A61B17/12
Filed: 1998-06-23
Granted: 2006-10-17
Abstract: A suture cartridge assembly is disclosed. The assembly has a suture cartridge containing a slot for receiving a suture filament and a cartridge top for covering at least a portion of the filament. A grasping jaw faces the cartridge top, and it is movable from an open position spaced from the cartridge top to a closed position adjacent the cartridge top. The slot in the cartridge for receiving the filament facilitates the formation and placement of surgical knots made from the suture filament, particularly when knots are needed at remote surgical sites such as during minimally invasive surgery. The placement and deployment of the knot is further facilitated because the grasping jaw can grasp the filament or the tissue which is desired to be sutured when the jaw is moved from its open to closed positions. The ability to grasp the filament or tissue enables the surgeon to manipulate the filament or tissue during the procedure for deploying and placing the knot, further facilitating the ease with which the surgeon can deploy and place the knots in a minimally invasive procedure.

Abstract: Inserts of metal 13 in the plastic 11 of the plastic structural element 57 are coated with a coupling layer 12 of fibre-reinforced plastic, which reduces the abrupt change in stiffness and/or coefficient of thermal expansion at the joining interfaces in the metal-plastic composite. By altering the volume fraction of fibres and/or by means of different orientation of the fibre layers within the coupling layer (12), a gradual change in the E-modulus and the thermal expansion coefficient are produced, as a result of which abrupt changes in these values at the composite interfaces can be avoided. The sudden change in stiffness between the plastic material 11 and the metal insert 13 is also reduced by reducing the stiffness of the insert 13, which again is achieved by specific choice of shape. Preferred, in particular, is a finger-shaped fanning out of the insert 13 in the plastic material 11.

Abstract: A pivot socket of the present invention incorporates a stud shaft component having a partially spherical head portion disposed within a housing cavity, and an axial pin extension extending upward into the cavity therefrom. The partially spherical head portion seats against a partial spherical bearing surface disposed within the housing cavity, and the axial pin extension is enclosed within a resilient cushion. During use, lateral and axial loads imparted on the stud shaft are transformed into radial and axial component forces at the bearing surfaces. The radial force components are distributed to the interior walls of the housing cavity, while the axial force components are transferred axially through the resilient cushion to the end closure components secured to the housing. Little or no lateral force components are transferred to the resilient cushion from lateral loads imparted on the stud shaft, thereby reducing wear on the pivot socket components and extending the useful life thereof.
