Suivant l'inventi...

The friction surface e.g. for interacting male and female components of artificial hip, knee or ankle joints, is produced by applying to the surface of a prosthesis substrate of a given hardness ( alpha ) a thin layer of a material of greater hardness ( beta ) after first forming a surface of an intermediate hardness ( psi ) between the two. The intermediate layer can be created by hardening the s...

The inventive idea is to set up by parts of forwarded call using services of a closed user group always leg-specifically. Hereby the user group data defined by the subscribers for the leg in question can be used for each leg. The user group data defined by the calling subscriber is used in that leg of the call which is between the calling subscriber and the call forwarding point. User group data d...

Stents are coated with a polymer such that the polymeric coating binds the crossover points of the wires, or, in the case of a zig-zag stent, binds adjacent zig-zags of wires without occluding the interstices of the stent lattice. Suitable polymers include polyurethane, polycarbonate urethane, polyurethane urea, silicone rubber, polyisobutylene copolymer (with styrene, etc.), polyolefin, polyester...

Process for ultrafiltration of particles in fluids by passing the fluids to be filtered across a filter element made of a parent rock taken from underground with micropores of a mean diameter less than a few hundred Angstroms. Device for the ultrafiltration of particles suspended in fluids with a box (1) enclosing ≥ 1 filter element (5) made from a parent rock taken from underground.

A set of quick release hubs for wheelchairs for physically handicapped persons with hemiplegic disability, characterized by two identical inserts (D1 & D2) located inwards from the hubs (M1 & M2) having quick release, being securely fastened into supports (10) provided on the wheelchair frame for the wheel location, each insert (D1 & D2) being coupled to each other on the inwards sides by an adjus...

L'invention concerne un procédé et un dispositif pour fabriquer des barquettes d'emballage multicouches pour des produits alimentaires qui libèrent des liquides, formées d'un empilage de bandes de matière thermoplastique avec une bande intermédiaire absorbante.
La bande multicouche est introduite à l'état plastique, dans un dispositif de moulage qui comporte un moule (2) et un poinçon (3), ...

A novel way of locking and unlocking an adjustment device for an artificial leg or arm makes it possible to perform an adjustment of the prosthesis, without necessitating disassembly of the prosthesis or the removal of the prosthesis from the patient. This facilitates the work in adjusting the translatory position and the angular position, and the adjustment device also offers a further degree of ...

The implant has a frame (1) defining an internal seating to be implanted in a cotyloidal cavity. It has a low friction material cup (10) which is rigid and inserted into the seating to receive the head (40) of a femoral prosthesis. There is a space (20) between the internal face of the frame and the external face of the cup. The frame has a flexible structure cooperating with the rigid cup to all...

The restraint comprises a movable part which slides in a fixed tube (7). The movable part has a portion forming a base (13) and a portion forming a lateral stop (3). A compression spring (20), housed in the fixed tube, maintains the movable part permanently in a retracted position partially engaged in the fixed tube. The stop and the base are made from a square folded wire pin (2) and the compress...

In semiconductor memory devices, failed memory cells are problematic because they draw excessive standby currents. To repair such devices before packaging, the failed memory cell columns are replaced by redundant columns. To ensure that a replaced column having a failed cell does not draw excessive standby current, the invention provides for turning off the precharge circuit transistor pair that o...
