Patent CA-2070498-A1 (CA)
Inventor: AGRAWAL RAKESH
IPC: C01B21/04
Filed: 1992-06-04
Abstract: This invention relates to a cryogenic process for the separation of air utilizing an integrated multi-column distillation system wherein an ultra high purity nitrogen product is generated.  In the cryogenic distillation separation of air, air is initially compressed, pretreated and cooled for separation into its components.  Ultra high purity, e.g., nitrogen having less than 0.1 ppm of light impurities is generated with enhanced nitrogen product recovery by withdrawing liquid nitrogen from a first column at an intermediate point and charging that fraction as feed to the second column, withdrawing a nitrogen stream which is rich in volatile contaminants from the top of the first column, partially condensing that nitrogen stream against crude liquid oxygen, and removing the uncondensed portion which has been concentrated in volatile contaminants as a purge stream.  An ultra high purity nitrogen product is obtained from a second column.

Abstract: A precision depth spindle is mounted to rotate within a cartridge but is restrained against axial movement with respect to the cartridge. The cartridge is mounted for axial sliding movement within a housing, but cannot rotate with respect to the housing. A tool chuck is fixed to one end of the spindle for movement with the spindle, the tool chuck supporting a cutting tool. A spindle stop is mounted to the tool chuck and can rotate with respect to the chuck. Thisallows the spindle stop to be maintained stationary while the tool chuck and thecutting tool rotate. The spindle stop is finely adjustable axially with respect to the tool chuck, thus determining the depth to which the cutting tool will enter a workpiece. The cartridge has a limited axial motion range with respect to the housing, and both the spindle and cartridge are urged toward the workpiece with respect to the housing by a suitable spring or pressure means.

Title: Prosthetic implant and method of making same
Inventor: DEVANATHAN THIRUMALAI
IPC: A61F2/36
Filed: 1993-11-01
Abstract: PROSTHETIC IMPLANT AND METHOD OF MAKING SAME          Abstract of the Disclosure This  invention  provides  for  a  prosthetic  implant having a porous surface layer connected to the implant body by the use of a thin layer of a thermoplastic polymer with a  melting  point  substantially  lower  than  the  metal components  and  which  exhibits  good  adhesive  bonding characteristics.     In  the  preferred  embodiment  the thermoplastic   polymer   of   choice is   from   the polyaryletherketone family  (PAEK).  Specifically, a PAEK sold by BASF under the trade name Ultrapek? A3000. The PAEK polymers have been shown through experimentation to exhibit strong adhesive bonds with molybdenum alloy (Co-Cr-Mo) and titanium-vanadium-aluminum alloy (Ti-6Al-4V) commonly used for implant materials.     The use of the thin film polymer bonding eliminates the  undesirable  effects  incurred  during  the  sintering process in two ways.  First, since the thin film polymer melts at a substantially lower temperature than required during  a  sintering  process,  the  implant  body  is  not subjected to high temperature.  Second, the porous coating and the implant are secured together without sintering; therefore, notches are not formed at the point of contact between the porous surface and the implant.     The resultant implant with a porous layer attached therefore retains substantially if not all the original strength characteristics of the implant body.  Therefore, designers of prosthetic implants are not limited in the amount or location of the porous surface layer on the implant.  Further, eliminating the sintering or diffusion bonding  process  reduces  the  cost  incurred  by  the manufacturer in the form of time and capital expenditures required to sustain the high temperature furnaces.
