    摘要： An improved string trimmer head is described. The trimmer head comprises a housing with a spool and spring assembly enclosed within the housing. The trimmer head further comprises a lid connected to the housing and a bump knob with a base and an intermediate member. The base of the bump knob is located inside the housing. The intermediate member extends outside the housing through the lid. The lid comprises an annulus which surrounds the base. The height of the annulus is greater than a maximum compressing distance of the spool when compressed by the bump knob. A segment of the intermediate member remains outside the lid when the spool is compressed. The bump knob further comprises a finger slot with an outer edge and a recessed portion. A bottom side of the outer edge is positioned farther away from the spool than the recessed portion.

    摘要： A muffler with a housing for receiving exhaust gasses from an engine is disclosed. The muffler includes a housing with an inlet and an exit, a baffle plate partitioning the housing into first and second chambers. The baffle plate includes a catalyst receptacle in the first chamber, the second chamber includes the exit of the housing. A catalytic converter element with a longitudinal axis is housed within the catalyst receptacle, the catalytic converter element is positioned within the catalyst receptacle such that exhaust gas passes through the catalytic converter element in a direction transverse to the longitudinal axis of the catalytic converter element and through the second chamber to exit the housing.

    摘要： A marine propulsion system includes a housing configured to be coupled to, or within, a marine vessel hull. At least one pair of counter-rotating impellers is disposed within the housing such that the rotation occurs in a plane generally parallel to the surface of the water. A moveable output nozzle is coupled to the rear portion of the housing and can move to facilitate controlling the direction of travel of the vessel.
