  • Vertical sliding valve arm
    Patent number: 10690020
    Abstract: Improvements in a vertical sliding valve arm has been disclosed with systems and methods related to eliminating the common pivot-type rocker arm and reversing the use of the valve spring in internal combustion engines. More specifically, the camshaft lobes activate a sliding valve arm to close the engine valve instead of opening it and the valve spring is used to push open the valve instead of closing it.

  • Coolant line hydrometer
    Patent number: 4649747
    Abstract: A hydrometer unit permanently connected in an engine coolant line enables an immediate visual check on the adequacy of the anti-freeze constituent, such as ethylene glycol, in the system. The hydrometer includes a coolant receiving chamber having a transparent viewing portion and a number of variously colored float elements within the chamber provide an accurate indication of anti-freeze strength based on specific gravity. No manipulation of the hydrometer is required to enable a checking of the strength or weakness of the anti-freeze.
