Pocket calculator for declining words in foreign language - has buttons for selection of word type and number with display for article and word ending(s) controlled by logic circuitry

摘要

The calculator has a number of logic gates through which paths are selected by pushbuttons. These buttons are arranged in sets of four to permit selection of the type and number for the words to be declined. These include the articles, pronouns, adjectives and verbs as well as prepositions. One set of buttons selects the case while supplementary buttons select personal pronouns or verbs with or without seperable particles. A display window permits display of the article declined and the ending for an adjective and for the substantive if they are modified by the declension. One light indicates the reset to zero condition and a second light indicates incompatibility of operation of certain pushbuttons.
