Troy A. Eidenschink has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6675991
    Abstract: A ram plate which allows easy lifting and dropping of the plate even when a complete seal has been made with high-viscosity liquids inside a barrel. The system contains two alternative methods of depressurizing the internal liquids in order to more efficiently avoid vacuum and suction effect when the user attempts to raise the plate. The bleed stick components of the plate are completely independent of vent ports components. Such bleed stick components are levers which, when depressed, will move a cover and expose the internal liquids to outside air pressure via air vents. The vent port components operate through both gravity and potential energy of an internal spring, which place a given amount of downward pressure on a pneumatic cylinder which may or may not be enough pressure to move the cylinder and expose a vent to the outside atmosphere pressure.

The system contains two alternative methods of depressurizing the internal liquids in order to more efficiently avoid vacuum and suction effect when the user attempts to raise the plate. The bleed stick components of the plate are completely independent of vent ports components. This allows the user to depressurize the internal air even if the high viscosity liquids fail to evacuate or drip from the vent ports, by way of opening a completely separate port that has not been filled with liquid. Such bleed stick components are levers which, when depressed, will move a cover and expose the internal liquids to outside air pressure via air vents.
