Abstract: A method of syntactically categorizing the constituents of English language sentences and a schema for depicting all possible categories to which the constituents of any sentence could belong. It also depicts the general order to appearance of the basic elements (foundation elements) in a sentence and their alignment according to the functions they perform in a sentence, the alignment being informative to a schema user of certain relationships between constituents of a common function.

Abstract: An educational system for teaching and learning English grammar and syntax comprising a plurality of sets of individually manipulable members, preferably cards, each representing a word. Each set comprises a plurality of identical members and the members from each set are distinguishable with respect to their color and shape taken together from the members of every other set. The color of each member is informative to the student of the use of the member in a sentence. The shape of each member is informative to the student of the type of word that the member represents. Each member either has a word imprinted upon it or is adaptable to receiving indicia. The user combines members to construct sentences. Preferably, the members are cards which are part of an educational kit.

Abstract: A novel sign usable for advertising or for decorative purposes, involving a mesh defining a large number of regularly recurring apertures, into which a number of colored chips may be easily installed in a pre-established pattern or configuration. By selective installation of the novel chips, letters and therefore words may be rapidly created, without it being necessary to expend the time or the money required in order to create a painted sign, or to utilize preformed letters. The novel chips may also be used for creating ornamental configurations, used alone or in conjunction with displays or symbols used in advertising. In the event the mesh used is in the nature of a chain link fence, having some dimension in the thickness direction, a display may be created on each side of the fence, with one display perhaps being entirely unrelated to the other. Further, a series of elongate members disposed in a parallel array between the chips may be utilized in order to create a pleasing background for the chips used.
