Abstract: Equipment for making a precut in a pack of food cups, wherein the precuts makes separation by breaking along a separation line between two food cups easier, where the equipment includes at least one knife for making a precut groove and/or a full cut along the separation line and at least one counter-knife.

Abstract: Pot with an undercut that includes a bottom wall (5), a side wall (6) that is closed on itself and connected to the bottom wall (5), with an opening providing access to the interior of the pot. The outside surface of the side wall of the pot has a non-symmetrical undercut shape for rotation around the vertical direction (Z). The outside surface has at least one vertical demolding plane (P) such that an undercut value of the pot with respective side ends of the pot, with a maximum side spacing of the outside surface in relation to the vertical demolding plane (P), is less than a maximum undercut value of the pot on the circumference of the outside surface of the pot.

Abstract: An index generator and query expander for use in information retrieval in a corpus. A corpus is provided as an input to an inflectional analyzer, which produces a lemmatized corpus having base forms and associated inflections for each word in the original corpus. The lemmatized corpus is provided as an input to a disambiguator, which performs part of speech tagging and morpho-syntactic disambiguation to produce a disambiguated corpus. The disambiguated corpus is provided as an input to a derivational generator, which produces an expanded corpus having all possible valid derivatives of each word of the disambiguated corpus. The disambiguated corpus is provided as an input to a transformational analyzer, using a grammar and a metagrammar for analyzing syntactic and morphosyntactic variations to conflate and generate variants, producing an index to the corpus having a minimum of variants. Alternatively, a query expander is provided utilizing similar techniques.
