[DML] Re: Broken torsion bar

["geoff_ombao" <geoff_ombao@xxxxxxxxx>]

Hmmm ... don't know if the Grumman patent is specific to a suspension
... to me it sounded like a claim on the process of manufacturing the
bars. The suspension references may only be example of their practical
application.

I think DMC might hold a patent on the use of a torsion bar on a
vertically opening car door. (See link)

Anyway, the Grumman patent seems to have some interesting info on
torsion bar manufacturing, and materials.

Enjoy!
