An exhaust valve assembly for a two stroke internal combustion engine having a cylinder with at least one main exhaust port and one auxiliary exhaust port is disclosed. The assembly comprises a main exhaust valve for at least partially closing the main exhaust port, an auxiliary exhaust valve for at least partially closing the auxiliary exhaust port, an actuator for actuating the main exhaust valve and the auxiliary exhaust valve, the actuator including a rotary shaft having a first gear and a second gear, the rotary shaft being operatively connected to the main exhaust valve via the first gear, the rotary shaft being operatively connected to the auxiliary exhaust valve via the second gear, an electric motor operatively connected to the rotary shaft for rotating the rotary shaft.

An integrated motor support and transmission apparatus for a marine propulsion system having a motor and marine drive with a drive shaft, comprising: an output shaft; a support housing attached to a marine vessel and having an upper end and a lower end, the upper end supporting the motor and the lower end substantially aligning the output shaft with the marine drive; and a transmission connecting the motor to the output shaft, whereby the motor, transmission, and output shaft can be installed in the marine vessel in a single operation.

A test pile comprises a hollow pile body. The lower portion of the pile body is located underground, and the pile body is located above or beside an underground pipeline. A test block pipe is installed in the pile body. A cabin door is arranged on the pile body. A wiring board is installed in the pile body. A test block is installed in the test block pipe. A reference electrode is installed in the pile body. The test block, the reference electrode and the pipeline are connected with the wiring board. The lower portion of the test pile is inserted underground, the test block is installed in the test block pipe, the reference electrode is installed in the lower end of the test pile, and therefore the lower portion of the test pile can be used as a reference pipe, and it is unnecessary to additionally install a reference pipe; installation and layout are simple, and the cost of whole pipeline cathode protection engineering is also reduced. When the reference electrode is calibrated, a working electrode for calibration can be conveyed to an underground position through the test pile, the working electrode is made to be close to the reference electrode to be calibrated as much as possible, and calibration is more accurate; the reference electrode to be calibrated can also be taken out to an overground position from the underground position along an inner cavity of the test pile, the reference electrode directly gets close to the working electrode on the ground, calibration is conducted, and therefore calibration accuracy is improved; moreover, the reference electrode and the test block can be taken out from the underground position and are convenient to replace and maintain.

A filter bag of a vacuum cleaner has a filter mounting plate that includes a generally strap-shaped securing element with pivot members on an end thereof. A housing of the vacuum cleaner defines a filter bag compartment therein and has pivot receivers into which the pivot members can be substantially vertically inserted. Then the filter mounting plate can be pivoted into a substantially horizontal installed position as the filter bag is inserted into the filter bag compartment. In the installed position, a first stop member of the filter mounting plate contacts and is stopped by a second stop member of the housing so as to prevent further pivoting and so as to properly position and hold the filter mounting plate.
