A three position fluid powered actuator having a piston reciprocally positioned within a cylindrical chamber in a body. The piston has a socket in communication with an axial opening through the piston. A piston shaft has a first end passing through the axial opening and into the socket and has a second end passing through a spring chamber in the body. A compression spring surrounds the piston shaft in the spring chamber. A pair of fluid passageways extend into the cylindrical chamber, whereby fluid pressure in a first passageway will move the piston in a first direction and fluid pressure in a second passageway will move the piston in a second direction.

A conveyor system for conveying pieces or units of mail, or similar articles, comprises a fixed side and a movable side. The fixed side comprises a first conveyor belt which has a first inner run section partially defining an article flow path and which is routed around a plurality of pulleys which have their axes fixed with respect to the article flow path. The movable side comprises a second conveyor belt which has a second inner run section cooperating with the first inner run section of the first conveyor belt so as to cooperate therewith in defining the article flow path and which is routed around a plurality of pulleys or wheels which are movable with respect to the article flow path so as to accommodate the conveyance of different articles, having different thickness dimensions, along the article flow path.

An apparatus for mounting a transducer to the rearward surface of the transom of a boat including a suction cup of resilient material which is retained on the boat transom when pressed against it, the suction cup having an integral rearward extending boss portion, a bracket having a vertical portion affixed to the cup boss portion and having a lower, rearwardly extending arm and an upper forwardly extending arm, a fastening bracket secured to the lower arm providing means of attaching a transducer to the bracket so that the transducer is held in an upright position with the lower face of the transducer tilted at an angle with respect to the horizontal when the boat is in the water, the cup boss portion being flexible so that when the boat moves with speed the transducer is permitted to be pivoted rearwardly relative to the boat transom with the upper bracket arm portion engages the rearward surface of the cup to limit the pivotation so that the lower surface of the transducer never has a negative angle with respect to the horizontal regardless of the speed of the boat.
