Title: Artificial joint, particularly an artificial hip joint
Inventor: SEMLITSCH MANFRED
IPC: A61F2/32
Filed: 1997-03-06
Abstract: PURPOSE: An artificial joint is provided to enable to use a metallic material with a wear resistance as a bearing socket and the joint ball in a spherical bearing while preventing an excessive wear. CONSTITUTION: This invention concerns an artificial hip joint with geometry which makes it possible to use same-type, wear resistant, metallic materials such as PROTASUL 21 WF for the bearing socket (1) and the joint ball (2) in a spherical bearing, without micro welding and excessive wear arising, while other properties such as tenacity, dimensional stability and elasticity can be exploited for the function of this joint. Micro welding of same-type metallic materials is largely prevented by a fitting relationship between the middle radii Rm, rm of bearing surfaces A and B, the allowable form deviations (12,13), and the allowable roughness of the bearing surfaces.

Title: Method of post-polymerization stabilization of high activity catalysts in continuous polyethylene terephthalate production
Inventor: MOORE TONY CLIFFORD
IPC: C08G63/88
Filed: 1997-05-20
Abstract: PURPOSE: In continuous production of polyethylene terephthalate polyester, post-polymerization activity of polymerization catalyst is demanded to be stabilized. CONSTITUTION: A continuous process for polyethylene terephthalate polyester from terephthalic acid and ethylene glycol uses a stabilizer, preferably containing phosphorous, to produce a high quality polyethylene terephthalate polyester which is relatively free of the acetaldehyde and discoloration which are associated with the post-polymerization activity of a polymerization catalyst. The stabilizer is preferably added at or after the end of the polymerization reaction prior to polymer processing to deactivate the polymerization catalyst and can increase the throughput of the polyester without adversely affecting the thermal stability of the polyethylene terephthalate polyester. Alternatively, the late addition of the stabilizer can increase the thermal stability of the polyester without adversely affecting the throughput of the polyethylene terephthalate polyester.

Abstract: PURPOSE: A method for allocating frame offset of a base station in a code division multiple access(CDMA) communication system, is provided to select a frame offset value having a largest call-allocation margin in a neighboring base station when setting up frame offset in an optional base station, so that a rate of a soft hand-off failure can be reduced as the corresponding base station has a high call allocation probability when soft hand-off is requested to neighboring base stations. CONSTITUTION: If a call is generated from a mobile station and frame offset allocation is requested to an optional base station, the base station informs a control station of the allocation request. The base station receives information on frame offset values having margins in allocating calls of neighboring base stations, and calculates self frame offset values. The base station decides whether self frame offset values having margins exist. If so, the base station confirms each number of neighboring base stations having call-allocation margins for each frame offset value having self call allocation margin, by using the received information on the frame off set values of the neighboring base stations. The calls are allocated with the biggest frame offset value among the numbers of the neighboring base stations.
