Latest Patents

Mahowald’s listed patent is titled “Installation for Distributing Pulverulent Substance by Pneumatic Transportation, Comprising a Device for Depressurizing a Pressurized Reservoir in Which Said Substance Is Stored.” It describes an installation with a dispensing hopper that can be pressurized to discharge material and depressurized to allow refilling.

The invention uses a depressurizing duct connected to the hopper and a pressure-capable bag filter. Flow-control means positioned downstream of the filter regulate the airflow so it does not exceed the filter’s maximum operating flow rate. The design is intended for applications such as injecting coal into a blast furnace.
