Patent number: 7942237Abstract: The present invention provides composite muffler systems formed of a long fiber thermoplastic. Long fiber thermoplastic technology allows the fibers, to maintain a length sufficient to provide structural strength at lower fiber loading. The long fiber thermoplastic material for forming composite muffler systems also provides increased impact strength and creep resistance as well as chemical and thermal resistance. Mufflers molded with long fiber thermoplastics demonstrate improved dimensional stability as compared to known short fiber based moldings. One suitable muffler structure is a multi-piece muffler assembly including at least one long fiber thermoplastic shell section. In accordance with the present invention, the long fiber thermoplastic material and moldings may also be combined with over-molding of preforms of unidirectional or woven inlays, which provide local structural performance.Type: GrantFiled: December 14, 2006Date of Patent: May 17, 2011Assignee: OCV Intellectual Capital, LLCInventors: Peter B. van de Flier, Norman T. Huff, Luc J L Brandt, Achim J. Reinartz

Publication number: 20080142295Abstract: In a method of forming a silencer preform from fibers of a fiberizable material, the fibers are fed into a mold, and a low temperature cure binder is applied to the fibers. The binder is cured at a low temperature to bond together the fibers, thereby forming a preform having generally the shape of the mold. The preform is removed from the mold. The preform is structured for insertion into a silencer. A silencer preform includes fibers of a fiberizable material and a low temperature cure binder bonding together the fibers.Type: ApplicationFiled: December 14, 2006Publication date: June 19, 2008Inventor: Norman T.

Patent number: 4338116Abstract: An electronic control system for an automatic glassware forming machine includes a plurality of position sensors for monitoring the motions of individual glassware forming mechanisms. The sensors generate output signals which define the start and stop times and/or motion of the respective forming mechanisms. The electronic control is responsive to the sensor output signals for identifying any mechanical dead times in the forming cycle. Mechanical dead time is defined as time during which no machine motions are occurring, but could be occurring without interfering with essential heat transfer functions. The electronic control can then reduce or remove selected mechanical dead times to reduce the machine cycle length, and consequently, increase the production rate of the machine.Type: GrantFiled: March 9, 1981Date of Patent: July 6, 1982Assignee: Owens-Illinois, Inc.Inventors: Norman T. Huff, Donivan M. Shetterly, Lawrence I. Kalisher
