| 20110011669 | SOUND DAMPENING AND WEAR PROTECTING FLAPPER CONFIGURATION FOR MARINE EXHAUST SYSTEM - Disclosed are apparatus and methodology for reducing noise and wear in a flapper configured exhaust tip for a marine exhaust system. A metallic flapper is located at an end portion of an exhaust tip of the exhaust pipe. An elastomeric flapper assembly is provided covering the exhaust tip and includes a lip portion configured to provide noise reduction by functioning as a stop for a tip portion of the metallic flapper. The metallic flapper is positioned such that a tip thereof contacts the elastomeric flapper assembly rather than the metallic exhaust pipe. Such contact with an elastomeric flapper assembly reduces noise previously produced by flapper contact with the hot exhaust pipe. | 01-20-2011 |
| 20100012422 | FLAPPER CONFIGURATION FOR MARINE EXHAUST SYSTEM - Disclosed are apparatus and methodology for reducing noise and wear in a flapper configured exhaust tip for a marine exhaust system. A flapper, normally located within an exhaust tip of a marine exhaust system, is relocated upstream of the point in the exhaust system where cooling water normally contacts the exhaust pipe. An exhaust tip is coupled to the upstream portion of the exhaust system by way of an elastomeric coupling device. The flapper is positioned such that a tip thereof contacts the elastomeric coupling rather than the metallic exhaust pipe. Such contact with an elastomeric coupling device reduces noise previously produced by flapper contact with the hot exhaust pipe occasioned by destruction and/or heat degeneration of elastomeric material generally associated with the flapper device. | 01-21-2010 |
| 20100000999 | UNDERGROUND TANK LOCK - Disclosed are apparatus and methodology for securing access to an underground device such as a storage tank. A lockable blocking plate is secured to a filler cap for an underground storage tank in a manner to inhibit access to the filler cap.
