An aspect of this invention is to save weight for low frequency shields. With this shape, manufacturers can use much thinner, lighter and cheaper gauges and achieve a better shielding factor. Almost any kind of magnetic shield which needs a bottom, and/or a lid could use this technology. Shields are used in e.g., satellite navigation systems, the smaller weight may have a big influence.
English translation: Theoretically the construction can reduce the so-called end-effects due to the mixture of the material directions (parallel and perpendicular). The claim is characterized in that metal, which is used as a shield in the low frequency range because of its chemical and physical properties (eg. B. 2.4545 or 1.3922 (DIN standard), only by mixing the material directions, in the specific example by the use of is combined cylinders and flat disks.
Well, if I got this right - this idea needs a disc from one side, combined with the rings in between a second disc (probably welded) on the backend. I haven´t seen any similar shield in my career and have to admit that I have seen hundrets of different types including deep-drawn parts and cryogenic shields...
I think the biggest benefit could be saving weight for large diameters on one hand - plus to save time during production as the diameter could be specified via standardization. Nevertheless you´d need an experienced team for the welding/stacking and fairly good final heat treatment under hydrogen I expect.
Last but not least, this shape is pretty much too complex to just analyse the effect theroratically, so I personally would give a sample a go to see if it works... Curious to see what experts from Amuneal, VAC and Magnetic Shields say..
It seems that bundles of pipes are combined with disks on the face side in order to get a shielding effect. But the cope of protection is not clear enough to evaluate this utility patent. May be useful to get a low weight shielding in a low frequency environment.
