    摘要: Hydrogen containing chlorosilanes, preferably trichlorosilanes, are prepared by reacting silicon tetrachloride with hydrogen at a temperature of 600.degree.-1200.degree. C. with a SiCl.sub.4 /H.sub.2 mixture having a molar composition between 1:1 and 1:50 in equilibrium with SiHCl.sub.3 and HCl and suddenly quenching the mixture to below 300.degree. C.

    摘要: A gear actuator for engaging and disengaging gears in an automatic manual transmission has a single working piston or two working pistons provided with a first working piston surface and a second working piston surface. An auxiliary piston is provided also. A pressure control valve controls a pressure supplied to the second working piston surface. A shut-off valve is provided. The first working piston surface and the pressure valve are supplied with a system pressure of a hydraulic system. The first working piston surface and the pressure control valve can be decoupled from the system pressure of the hydraulic system by the shut-off valve.

    摘要: SUBSTITUTED S-TRIAZINE COMPOUNDS OF THE FORMULA

    2-X,4-(R5-N(-R6)-C(=S)-C(-R3)(-R4)-NH-),6-(R1-N(-R2)-)-

    S-TRIZINE

    WHEREIN X IS HALOGEN, N3, LOWER ALKOXY OR LOWER ALKYLMERCAPTO; R1 AND R2 ARE THE SAME OR DIFFERENT AND ARE HYDROGEN, LOWER STRAIGHT-CHAIN OR BRANCHED ALKYL, LOWER STRAIGHTCHAIN OR BRANCHED AKLENYL, LOWER STRAIGHT-CHAIN OR BRANCHED SUBSTITUTED ALKYL OR LOWER STRAIGHT-CHAIN OR BRANCHED SUBSTITUTED ALKENYL; R3 AND R4 ARE THE SAME OR DIFFERENT AND ARE STRAIGHTCHAIN OR BRANCHED ALKYL OR ALKENYL HAVING FROM 1 TO 8 CARBON ATOMS OR ARE ARALKYL AND WHEREIN R3 AND R4 MAY ALSO BE INTERCONNECTED TO FORM A 5 TO 7 MEMBER RING AND WHEREIN EITHER R3 OR R4 MAY ALSO BE HYDROGEN; AND R5 AND R6 ARE THE SAME OR DIFFERENT AND ARE LOWER ALKYL OR HYDROGEN. THE COMPOUNDS OF THE REACTION ARE STRONG HERBICIDES OF A HIGHLY SELECTIVE NATURE. THE INVENTION ALSO COMPRISES A PROCESS OF MAKING THE COMPOUNDS WHEREIN A CYANURIC CHLORIDE IS REACTED WITH A,A-DISUBSTITUTED-AMINOACETIC ACID-THIOAMIDE IN THE MEDIUM OF AN INERT ORGANIC SOLVENT FOLLOWED BY RECOVERY OF THE FORMED PRECIPITATE.
