  2. Propeller walk - Wikipedia

    en.wikipedia.org/wiki/Propeller_walk

    Propeller walk (also known as propeller effect, wheeling effect, paddle wheel effect, asymmetric thrust, asymmetric blade effect, transverse thrust, prop walk) is the term for a propeller's tendency to rotate about a vertical axis (also known as yaw motion). The rotation is in addition to the forward or backward acceleration.

  3. Paddle wheel - Wikipedia

    en.wikipedia.org/wiki/Paddle_wheel

    The paddle wheel is a device for converting between rotary motion of a shaft and linear motion of a fluid. In the linear-to-rotary direction, it is placed in a fluid stream to convert the linear motion of the fluid into rotation of the wheel. Such a rotation can be used as a source of power, or as an indication of the speed of flow.

    en.wikipedia.org/wiki/List_of_extant_paddle_steamers

    The paddle steamer Piemonte (1904) operates on Lake Maggiore, and sister paddle steamers Patria (1926) and Concordia (1926) operate on Lake Como. Former paddle steamers Italia (1909) and Giuseppe Zanardelli (1903) operate on Lake Garda; their steam engines, unlike in the ships that sail on lakes Como and Maggiore, were replaced with diesel ...

    en.wikipedia.org/wiki/Marine_propulsion

    The paddle wheel is a large wheel, generally built of a steel framework, upon the outer edge of which are fitted numerous paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels underwater. Rotation of the paddle wheel produces thrust, forward or backward as required.

    Two light switches in one box. The switch on the right is a dimmer switch. The switch box is covered by a decorative plate. The first light switch employing "quick-break technology" was invented by John Henry Holmes in 1884 in the Shieldfield district of Newcastle upon Tyne. [1]

    The British side-wheel paddle steamer SS Great Western was the first steamship purpose-built for regularly scheduled trans-Atlantic crossings, starting in 1838. In 1836 Isambard Kingdom Brunel and a group of Bristol investors formed the Great Western Steamship Company to build a line of steamships for the Bristol-New York route. [ 14 ]

  9. Level sensor - Wikipedia

    en.wikipedia.org/wiki/Level_sensor

    Rotating paddle level sensors are a very old and established technique for bulk solid point level indication. The technique uses a low-speed gear motor that rotates a paddle wheel. When the paddle is stalled by solid materials, the motor is rotated on its shaft by its own torque until a flange mounted on the motor contacts a mechanical switch.
