20110062210 | TWO-STAGE, FLAT CLINCHING STAPLER - A stapler comprises a mechanism to first fully drive staples into sheets of materials, e.g., paper, and only then to fold over the legs of the staples. This results in a flat clinch and very few crumpled staples. An anvil table is locked in a raised position above a staple anvil, and a trigger mechanism will operate only when a staple blade has proceeded through a staple magazine and forced a staple fully out. The trigger mechanism slides back when this happens, and unlocks the anvil table so it can drop down around a staple-leg-folding anvil. The whole top of the stapler and the papers being stapled drop with the already fully inserted staple onto the anvil to fold the staple legs over flat. | 03-17-2011 |

20080227957 | Reducing Immunogenicities of Immunoglobulins by Framework-Patching - Framework (FR)-patching is a novel approach to modify immunoglobulin for reducing potential immunogenicity without significant alterations in specificity and affinity. Unlike previous described methods of humanization, which graft CDRs from a donor onto the frameworks of a single acceptor immunoglobulin, we patch segments of framework (FR1, FR2, FR3, and FR4), or FRs, to replace the corresponding FRs of the parent immunoglobulin. Free assortment of these FRs from different immunoglobulins and from different species can be mixed and matched into forming the final immunoglobulin chain. A set of criteria in the choice of these FRs to minimize or eliminate the need to reintroduce framework amino acids from the parent immunoglobulin for patching is described. The approach gives greater flexibility in the choice of framework sequences, minimizes the need to include parent framework amino acids, and, most importantly, reduces the chances of creating new T- and B-cell epitopes in the resultant immunoglobulin. | 09-18-2008 |
