Tidal bundle Tidal bundle A tidal bundle is a sedimentary structure that forms in tidal areas as a result of spring and neap tides. A tidal bundle sequence can be seen as a variation in bed thickness with a periodicity of 14 days (diurnal) or 28 days (semidiurnal). During the neap tide, when the tidal current strength is weakest, smaller quantities of finer grains are deposited. As the tidal variation grows larger, towards the spring tide, larger quantities of coarser material will be deposited which results in an increasing bed thickness. Bed thickness will be greatest at the spring tide and then
European Convention relating to the Formalities required for Patent Applications European Convention relating to the Formalities required for Patent Applications The European Convention relating to the formalities required for patent applications was signed at Paris on December 11, 1953. Its aim was to "simplify and unify, as far as it is possible, the formalities required by the various national legislations for patent applications". It was open to the signature of the members of the Council of Europe, came into force on June 1, 1955, and, after it came into force, became open to accession by all States which are members of the International Union for the Protection of Industrial Property.
