Manfred Dammann 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).

  • Process for the uniform introduction of a fluid, and apparatus for carrying out the process
    Patent number: 5095930
    Abstract: A distributor tube has tube slots in its shell surface transversely of the inflow direction of a fluid into the distributor tube. A casing tube is enclosed by the distributor tube and is divided into flow chambers, each of which is bounded by two annular plates and connected to an inlet sector. A star-shaped volume flow divider is located on the inlet side of the distributor tube as a tube insert, which divides the introduced mass flow rate into partial flow rates for the flow chambers. In another embodiment, the distributor tube encloses a rotationally symmetric pressure distributor, whereby the fluid within the distributor tube encounters equal pressure in the radial and axial flow directions over the inlet length of the distributor tube.
    Type: Grant

  • Process and device for drying a liquid layer applied to a moving carrier material
    Patent number: 4999927
    Abstract: A process for drying a liquid layer which has been applied to a carrier material moving through a drying zone and which contains vaporizable solvent components and non-vaporizable components, wherein a drying gas flows in the longitudinal direction of the carrier material parallel to the liquid layer and is accelerated in the drying zone in the direction of flow, is disclosed. Also disclosed is a device for accomplishing the drying process, comprising a drying channel through which the carrier material bearing the liquid layer runs in the longitudinal direction, and a gas-permeable channel-covering surface, through which the gas stream flows into the drying channel.
