Abstract: A marine engine muffler is provided having a silencing element with an inclined surface defining an array of elongate slotted apertures generally disposed in circumferential alignment. The slotted apertures are preferably defined by angled sidewalls such that exhaust gas flowing therethrough is forced to travel in a path that forms a reverse angle relative to the overall exhaust flow path thus conducting exhaust gases and entrained water to reverse direction while flowing through the silencing element. The conical silencing element is specifically sized to avoid resonant vibration within the operational RPM range of the engine and is further sized relative to the combined displacement of the engine and/or cylinder bank in fluid communication therewith to avoid resonant vibrations caused by reflected exhaust gas pressure waves generated by the internal combustion engine.

Abstract: A manual override mechanism is presented for a motor-driven linear actuator that allows the output rack and pinion of the actuator to be manually positioned. Once positioned, the output may be locked by a locking mechanism to prevent this output from translating to its quiescent position. When incorporated in a spring-return linear actuator, the manual override may be used to apply a preload on the spring before the driven device is connected. When the actuator is used to drive a valve or damper, the preload applies a positive closing force on the valve or damper in its zero position to ensure a tight closure of the valve or damper. The locking mechanism engages the gear train and opposes the closing force applied by the spring return of the actuator. To disengage the locking mechanism automatically, the motor applies a forward kick to the gear train. Manual disengagement is also provided.
