| 20100046826 | METHOD AND SYSTEM FOR USE IN INSPECTING AND/OR REMOVING UNSUITABLE OBJECTS FROM A STREAM OF PRODUCTS AND A SORTING APPARATUS IMPLEMENTING THE SAME - Disclosed is a method and system for inspecting and sorting unsuitable or irregular objects in a stream of products, the system includes means for scanning the stream of products along a scan line. The scan line is formed by means of at least one light source directing light along the scan line, and means for detecting light beams reemitted by the product stream upon scanning. The scanning means includes a focusing means for concentrating the light in at least one dimension. The detecting means includes a focusing means for forming an image in an image plane. The detecting means is oriented towards the scan line such that points on the scan line form a projected scan line in the image plane and the image substantially located in the image plane is substantially focused in at least one dimension by the focusing means. The detecting means also includes a spatial filtering means that filters the image in substantially the direction perpendicular to the direction of the projected scan line. | 02-25-2010 |

| 20100144930 | OXIDATION RESISTANT HIGHLY-CROSSLINKED UHMWPE - The present invention relates to highly cross-linked UHMWPE, which is possessed of an improved oxidation resistance, as well as a method for making the same. The UHMWPE material of the current invention is combined with an anti-oxidant compound or a free-radical scavenger prior to formation. Once the UHMWPE with the added material has been formed and treated with gamma or electron beam irradiation, it shows an improved wear resistance and also a good resistance to oxidation. Such a material, is particularly interesting for the field of making replacement joint implants. | 06-10-2010 |
| 20110112646 | ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE FOR BEARING SURFACES - A prosthetic device may comprise an insert having a first surface configured to contact a first prosthetic component and a bearing surface configured to articulate against a second prosthetic component. The insert comprises an ultra-high molecular weight polyethylene and vitamin E. The vitamin E may have a concentration in the range of 0.02 to 0.12 wt % first mixed with the ultra-high molecular weight polyethylene and then molded with the ultra-high molecular weight polyethylene at a temperature greater than the melting point of the ultra-high molecular weight polyethylene. The ultra-high molecular weight polyethylene and vitamin E may be gamma irradiated with a dosage of radiation between 5 and 20 Mrad. The insert may be machined prior to gamma irradiating the insert in air such that the gamma irradiation, at suitably high dosages, may also sterilize the insert. | 05-12-2011 |
| 20110116968 | OXIDATION RESISTANT HIGHLY-CROSSLINKED UHMWPE - The present invention relates to highly cross-linked UHMWPE, which is possessed of an improved oxidation resistance, as well as a method for making the same. The UHMWPE material of the current invention is combined with an anti-oxidant compound or a free-radical scavenger prior to formation. Once the UHMWPE with the added material has been formed and treated with gamma or electron bean irradiation, it shows an improved wear resistance and also a good resistance to oxidation. Such a material, is particularly interesting for the field of making replacement joint implants. | 05-19-2011 |
