Abstract
A novel pourable packing element is provided herein for use, in particular, in mass transfer and/or heat transfer towers through which a gas or a liquid flows. The exchange areas of such packing element are formed by the surfaces of half-wave-shaped or wave-shaped strips. The packing element possesses at least a first group of strips having a first periodic length and at least one adjoining second group of strips having at least one strip with a second periodic length. The first periodic length of a selected first strip in the first group of strips, (such selected first strip adjoining the second group of strips), and the second periodic length of a selected second strip in the second group (such selected second strip adjoining the first group of strips), is matched to each other in such a way that two adjoining strips of the first group of strips and the second group of strips are in contact with one another at at least one point, so that liquid can pass from one strip to the other strip.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
