Huckerby} 15.8.39. We are considering building a suspension shock damper in which the driver's control is a variable leak. We know that Luvax and Delco have used variable leak shock absorbers. Can you say if there is any patent which would prevent us from using this system. Rm {William Robotham - Chief Engineer} /AFM. {Anthony F. Martindale} | ||
