PATENT ABSTRACTS
exception of CF3, a (substituted) aromatic radical, (substituted) heteroaryl, (substituted) phenoxy, (substituted) phenylthio, (substituted) phenylamino, halogen, hydroxyl, alkoxy, mercapto, (halogenated) cycloalkyl, alkylmercapto, amino, monoalkylamino or dialkylamino, R1 denotes (substituted alkyl, (substituted) phenyl or naphthyl, alkenyl, alkinyl, cycloalkyl, (substituted) benzyl or heteroaryl, and X denotes oxygen or sulfur, which comprises reacting a nitrile of the formula II with a compound of the formula III See Patent for Tabular Presentation PS See Patent for Tabular Presentation PS in the presence of anhydrous hydrofluoric acid, a perfluoroalkanecarboxylic acid, a perfluoralkanesulfonic acid or a perfluorinated ion exchanger containing sulfonic acids, and converting the resulting salts of the formula I, if appropriate by the addition of bases, into the free imidates of the formula I and, if approximate, converting the latter subsequently into further salts or acid addition compounds. The invention also relates to the new compounds of the formula I in which R1 denotes a (substituted) phenyl radical and R and X have the meanings mentioned. The compounds of the formula I are valuable intermediate products in the preparation of plant protection agents and pharmaceuticals. 4727155 OXAZOLINONE COMPOUNDS USEFUL AS INTERMEDIATES FOR THE PREPARATION OF INSECTICIDAL AND ACARICIDAL AGENTS David G Kuhn assigned to American Cyanamid Company The present invention relates to novel oxazolinone compounds and a method for the preparation thereof. These compounds are useful intermediates in the preparation of cinnamamide insecticides and acaricides.
multiplier in a computer system is basically constituted by a multiplier and a carry propagating adder. The multiplier obtains a sum and carry per each bit by using carry save adder trees having a plurality of carry save adders, and generates a carry generation function and a carry propagation function based on the sum and carry by using a generation/propagation unit. The carry propagating adder obtains a final product based on the carry generation function and carry propagation function, and the carry generation function and carry propagation function generated by the generation/propagation unit are fed back to a final stage of the carry save adder. 4727768 TRANSMISSION FOR AGRICULTURAL TRACTOR Tetsuaki Hayashi, Hiroyuki Ogasawara, Nobuyuki Yamashita, Fumihiro Ikeda, Niro Bando, Kazuaki Kurohara, Osaka, Japan assigned to Kubota Ltd A transmission for an agricultural working vehicle is provided which includes a gear type forward speed changing mechanism and a wrapping connector backward driving mechanism selectively operable to connect an input shaft and an output shaft. The input shaft carries a plurality of change speed gears and a driving sprocket fixed thereto. The output shaft carries a driven sprocket relatively rotatably mounted thereon and operatively connected to the driving sprocket by a wrapping connector, and a shift gear slidably splined thereto and including gear portions selectively engageable with the change speed gears. The shift gear is linked to the driven sprocket by an engagement mechanism to provide a backward drive state when shift gear assumes a position other than change speed positions.
