20100247944 | HYDROGEN-PERMEABLE MEMBRANE MADE OF A METAL COMPOSITE MATERIAL - The invention relates to a metal matrix material made of a hydrogen-permeable metal 1 and a chemically stable metal 2 that is also hydrogen permeable, said matrix material having a structure comprised of a plurality of centers made of the metal 2 surrounded by the metal 1. The invention further relates to a method for the production of said matrix material, having the following steps: a. optionally pretreating the metal 1 and/or 2 b. coating metal 1 with a metal 2 to form a composite metal powder c. pressing the composite metal powder into the metal matrix material according to the invention in the form of a pressed body d. optionally deforming the pressed body thus obtained to form a molded body. The metal matrix material has a greater mechanical stability as compared to a conventionally coated metal film by virtue of a more homogeneous stress distribution during the change in volume of the metal phases as a result of hydrogen absorption and thermal expansion. At the same time, said material is considerably more chemically stable than conventional coated metal membranes. The metal matrix material is particularly suitable for producing hydrogen-permeable membranes that separate hydrogen from gas mixtures by selective diffusion. | 09-30-2010 |

20130124530 | Blood-Type Matching System - An interactive website, preferably hosted on a secured server, fashioned to simplify and expedite the dating process by matching individuals to other individuals of the opposite sex based primarily on the compatibility of the individuals' blood-types. With respect to the online service of the present invention, blood-type matches are suggested based on the compatibility of a hypothetical blood donation flowing from male to female. Knowledge of one's blood-type is required to become a user. Other characteristics may be implemented to help narrow search results, which may be edited on a user's profile page, distinguishing individuals by preferences, qualities, and appearance. | 05-16-2013 |
