Abstract: The invention relates to a method and a tool for fabricating a toothing at a three-dimensional body produced by forming and fine blanking, especially an attachment for car seat components or the like produced out of a flat strip, wherein the flat strip by forming and fine blanking in a tool is formed into a pot-shaped body with placed in the base of the body inner forms like impressions and/or projections and/or indentations and/or recesses and/or sinks and/or holes and/or pivots and a substantially evenly curved edge and afterwards into the edge is fabricated a toothing radially extending to the inner side of the body. The invention has the object to improve a method and a device for the fabrication of a toothing at a pot-shaped body produced by forming and fine blanking in a way, that the fine blanking of toothings is economically applicable also in case of dynamically balanced three-dimensional bodies such as hinge attachments with simultaneously increasing dimensional accuracy of the toothing, wherein the process safety increases because of the cessation of the heat treatment and the tool can be designed more compact. This object is solved by that the toothing in the edge of the pot-shaped body is exclusively produced by cutting or shaving with a fine blanking die or a shaving device and wherein aburr or shaving ch ips developing during cutting or shaving is pressed into a recess in the base of the pot-shaped body allocated to the toothing.

Abstract: A fuel system for an energy conversion device includes a deoxygenator system with an oxygen permeable membrane formed from a multiple of layers. T he layers include a sealant layer, an oxygen permeability layer and a porous backing layer. The layered composite oxygen permeable membrane maximizes the oxygen transfer rate and minimizes the fuel leakage rate.
