A shredder paper feed mechanism and paper feeder that, simply by setting a paper stack in the paper tray, enable a stack of document sheets to be fed to the shredder in an amount that matches the shredding capability of the shredder. This is done by using first and second rotating members equipped with claw members. The paper feed mechanism utilizes the transmitted rotary driving force of the shredder unit. The paper feed mechanism has a first rotating member having disc-shaped claw members with sharp portions for feeding the paper sheets, and rotation members; a transport roller; a second rotating member that limits the number of paper sheets that are fed onwards, and also has disc-shaped claw members with sharp portions for feeding the paper sheets, and rotation members; and a pressure roller that presses against the second rotating member to thereby grip and feed the paper sheets.

A burner fuel mixer head includes a primary housing and a secondary housing. The primary housing has a fuel/air mixing chamber with a mixed fuel gas inlet. The secondary housing has a fuel mixing chamber. A venturi throat with converging sidewalls is positioned in the mixed fuel gas inlet of the primary housing. A venturi nozzle communicates with a pressurized fuel gas inlet with a first end of the venturi nozzle extending into the fuel mixing chamber in axial alignment with the venturi throat. This forms a venturi, such that a pressurized flow of pressurized fuel gas through the venturi draws low pressure fuel gas from the fuel mixing chamber of the secondary housing through the mixed fuel gas inlet into the fuel/air mixing chamber of the primary housing.
