摘要： A method of surface hardening titanium orthopedic implant devices, and a titanium orthopedic implant device prepared by the disclosed method. An orthopedic implant device made of pure titanium or a titanium alloy, such as Ti-6Al-4V (ELI) is exposed to molecular nitrogen gas at a process temperature and for a process time duration sufficient to enhance surface hardness and wear resistance properties, without the formation of a measurable TiN layer that tends to increase surface roughness and diminish wear resistance properties. The process temperature is in the range of 750.degree. F. to 1300.degree. F., preferably about 1100.degree. F. and the process time duration at the preferred process temperature is approximately 8 hours. The hardened surface of the titanium implant occurs primarily due to solid solution hardening of the titanium with nitrogen by dissolution.

摘要： The present invention relates to a prosthetic interpositional device/coupler designed to be interposed between the neck and head of a femoral prosthesis. One example of a contemplated environment of use of the inventive interpositional device/coupler is in the situation where the prosthesis has a neck of one material and a head of another material. The inventive interpositional device/coupler may be made with an outer wall having a taper designed to match the taper of the head and with an inner wall having a taper designed to match the taper of the neck. These tapers may differ. Additionally, the inner and outer surfaces may have different surface textures from one another so as to make the respective walls compatible with the surface texture of the material of which the adjacent structure, head or neck, is made. Three embodiments of the inventive interpositional device/coupler are disclosed. The third embodiment is similar to the second embodiment except that the end wall is much thicker than the end wall in the second embodiment so that the device is greater in length than the second embodiment. The first embodiment does not include an end wall and may be shorter in length than either the second or third embodiment.

摘要： An implant stem 10 and distal centralizer 20. Implant stem 10 has a plurality of longitudinal channels 14 formed around its periphery adjacent its distal end 12. Channels 14 converge radially toward the apex of the stem distal end 12. Channels extend only partially into the body of implant stem 10 to provide sufficient material to maintain the structural integrity of the distal end of the implant. Centralizer 20 includes a plurality of radially extending blades 22. The proximal end of each blade 22 is shaped to extend upwardly for securely mating with implant stem 10. The complimentary cruciate configuration of channels 14 and blades 22 allows centralizer 20 to be securely attached to implant stem 10.

摘要： An air purifier with a tub capable of containing a liquid. Reactor plates are in the tub wherein the reactor plates provide a curvilinear path for air flow with abrupt directional change. A pump is situated to distribute the liquid onto the reactor plates to form a moist surface. An air inlet brings contaminated air into contact with biocatalyst on the moist surface thereby forming purified air. An air outlet discharges said purified air from the air purifier.
