  2. Water timer - Wikipedia

    en.wikipedia.org/wiki/Water_timer

    The solenoid/diaphragm timer uses more battery power throughout the "on" cycle because the solenoid must be actuated the entire time that the water flow is "on". The ball valve timer using the motor and gear actuator only uses more battery power during the few seconds that motor is used to turn the water flow on or off.

  3. Water brake - Wikipedia

    en.wikipedia.org/wiki/Water_brake

    Schematic water brake on a dynamometer A 4-minute ‘how-it-works video’ tutorial explaining how engine-dynamometer water-brake absorbers work. A water brake is a type of fluid coupling used to absorb mechanical energy and usually consists of a turbine or propeller mounted in an enclosure filled with water. As the turbine or propeller turns ...

  4. DC injection braking - Wikipedia

    en.wikipedia.org/wiki/DC_injection_braking

    A DC injection brake system can be used as an alternative or addition to a friction brake system. DC injection brakes only require a small module located with the other motor switchgear and/or drivers, mounted in a remote and convenient location, whereas a friction brake must be mounted somewhere on the rotating system.

  5. Retarder (mechanical engineering) - Wikipedia

    en.wikipedia.org/wiki/Retarder_(mechanical...

    Exhaust brakes are simpler in operation than an engine brake.Essentially, the exhaust pipe of the vehicle is restricted by a valve.This raises the pressure in the exhaust system, forcing the engine to work harder on the exhaust stroke of its cylinders, so again the engine is acting as an air compressor, with the power required to compress the air being withheld from the exhaust pipe, retarding ...

  6. CRC Industries - Wikipedia

    CRC's first product, 5-56, is still sold. However, 6-56, a silicone-based replacement, is CRC's current competing product for WD-40. [5] Brakleen, a tetrachloroethylene (PERC)-based brake cleaner, is one of CRC's signature products. It has gained a cult following due to its dissolving power and has been used off-label for many other purposes, a ...

  7. Electromagnetic brake - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_brake

    Electromagnetic brakes or EM brakes are used to slow or stop vehicles using electromagnetic force to apply mechanical resistance (friction). They were originally called electro-mechanical brakes but over the years the name changed to "electromagnetic brakes", referring to their actuation method which is generally unrelated to modern electro-mechanical brakes.

  9. Water softening - Wikipedia

    en.wikipedia.org/wiki/Water_softening

    Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes
