Abstract: A game comprises a playing surface having two fields of play. In a first field, a plurality of multiple choice questions are set forth, each choice being identified by a particular symbol. On a second field of play, these symbols are assembled to form a solution which answers a further question. In a preferred embodiment, answers can be selected to the multiple choice questions which will provide an acceptable, but incorrect, answer on the second field of play. In a particular embodiment, the symbols dictated by the choice of the answer to the questions in the first field of play are letters, and the solution formed in the second field of play is a word.

Abstract: A diamond segmented saw blade having a steel center is provided with a plurality of sockets about the rim and a plurality of cutting tip supports having diamond impregnated tips. Each socket is provided with an upper surface inclined upwardly and inwardly and a tapered or wedge-shaped dovetail groove. Each support is provided with a depending tenon. The surfaces adjacent the tenon are inclined upwardly and inwardly complementary to the surfaces adjacent the socket. The tenon is similarly wedge-shaped to fit in the dovetail groove so that the support and socket are firmly interlocked to insure easy and free exchange of diamond impregnated tips.

Abstract: An apparatus for thermochemical treatment of crushed straw and/or dry fodder mixtures comprises a vessel which is vertically mounted and is formed by a series of vertically communicating chambers. A chamber arranged at the top of the vessel is a cyclone-type chamber, is designed for moistening and pre-heating of crushed straw and dry fodder mixture and has a loading opening. A second chamber is arranged under the cyclone-type chamber, is designed for thermochemical treatment of straw and dry fodder mixtures and has a heat distributor communicating by means of a pipeline with a heat carrier source. A third chamber is arranged under the chamber for thermochemical treatment and is an accumulating chamber having an unloading opening. This construction of the apparatus enables the elimination of the step of stirring of straw, considerably simplifies the operation, improves the output and reduces the time for processing of straw and dry fodder mixtures.
