The glow plug (11) comprising a combustion chamber pressure sensor (19) is preferably used in the automobile industry.Type: ApplicationFiled: July 18, 2005Publication date: December 4, 2008Applicant: ROBERT BOSCH GMBHInventors: Oliver Glock, Christoph Kern, Steffen Schott, Jan Bahlo, Pavlo Saltikov

Patent number: 7402777Abstract: High sparking initiator compositions with a controlled amount of power are disclosed. The initiator compositions comprise a metal containing oxidizing agent, at least one metal reducing agent, and a non-explosive binder. Low voltage igniters that provide bidirectional plumes upon ignition are also disclosed. These igniters have a electrically resistive element positioned across a hole in a support which directs the plume. These igniters and compositions are useful in the actuation of solid fuel heating unit, in particular, sealed heating units.Type: GrantFiled: May 20, 2004Date of Patent: July 22, 2008Assignee: Alexza Pharmaceuticals, Inc.Inventors: Hale L. Ron, Mingzu Lei, Hilary N. Pettit, Dennis W. Solas, Soonho Song, Curtis Tom

Patent number: 7332690Abstract: A hot wire igniter for igniting a gaseous or atomized fuel is disclosed. The coil of the hot wire igniter is formed from a thin high temperature, iron, chromium, aluminum alloy having a center section that is tightly wound. The coil turns initially do not touch one another and each end of the coil is attached to a rod that is received within an insulator member. The rods are connected to a power source. The coil portion of the hot wire igniter is received within a gas collector box which is attached to the burner to be ignited. Application of the power source to the lead-in rods causes the coil of wire to reach a temperature in excess of the ignition temperature of the fuel mixture which surrounds same causing the ignition of the mixture.Type: GrantFiled: June 12, 2006Date of Patent: February 19, 2008Assignee: Channel Products, Inc.Inventors: Mark D. Schmiedlin, David J. Horvath
