摘要:
The invention relates to new plant growth regulating compositions, which contain as active agent 0.001 to 95% by weight of one or more compound(s) of the general formula (I), ##STR1## wherein R.sup.1 and R.sup.2 each represent hydrogen atom, a C.sub.1-5 alkyl group, a C.sub.5-7 cycloalkyl group, an aryl group, a halogen-substituted aryl group, an aralkyl group, a C.sub.2-5 alkenyl group or a C.sub.2-5 alkynyl group, orR.sup.1 and R.sup.2 form, together with the adjacent nitrogen atom, a morpholino, pyrrolidino, piperidino or perhydroazepinyl group, andR.sup.3 stands for hydrogen or a C.sub.1-5 alkyl group,together with an inert, solid, liquid and/or gaseous carrier or diluent, and optionally one or more additives, such as surfactants or other substances of plant biological activity.The compounds of the general formula (I) in which R.sup.1 is hydrogen and R.sup.2 stands for hydrogen, C.sub.1-3 alkyl, aralkyl or C.sub.3-5 alkenyl group, furthermore in which R.sup.1 and R.sup.3 are hydrogen and R.sup.2 is an aryl group have already been described in the literature, whereas the remaining derivatives of the general formula (I) are new. These compounds can be prepared by reacting a compound of the general formula (II) ##STR2## with an amine of the general formula (III), ##STR3## or by alkylating a compound of the general formula (IV). ##STR4## In the above formulae X stands for halogen, hydroxy or C.sub.1-4 alkoxy, whereas R.sup.1, R.sup.2 and R.sup.3 have the meanings as defined above.

Racemic or optionally active 2-(propargyloxyimino)-1,7,7-trimethyl-bicyclo[2,2,1]heptane of the formula (I) ##STR1## or a mixture of these isomers is prepared by reacting a racemic or optically active 1,7,7-trimethyl-bicyclo[2,2,1]heptane derivative of the general formula (II), ##STR2## wherein Y stands for oxygen atom, sulfur atom or oxime group, with a propyne derivative of the general formula (III),R--CH.sub.2 --C.tbd.CH (III)whereinR stands for halogen atom or aminooxy group, with the proviso that if Y represents oxime group, R may stand only for halogen, and if R represents aminooxy group, Y may stand only for oxygen or sulfur atom.The resulting product is new and possesses strong plant growth promoting and insecticidal effects.This is a division of application Ser. No. 065,156, filed Aug. 9, 1979, now U.S. Pat. No. 4,244,888, Jan. 13, 1981.

The invention relates to new N-substituted amino propane sulfonic acid derivatives of the Formula I ##STR1## and salts and hydrates thereof, a process for the preparation thereof and plant growth regulating agents comprising the same whereinR.sup.1 and R.sup.2 may be identical or different and stand for hydrogen, halogen, lower alkyl or lower alkoxy andR stands for furyl; or lower alkyl or phenyl the two latter groups being optionally substituted by one or more halogeno atom(s).
摘要:
The subject of the invention relates to an optical fibre sealing unit that contains a basic bundle consisting of light-transmitting fibres, a signalling bundle also consisting of light-transmitting fibres, a cable sheath and receiving bodies positioned at both ends of the cable sheath, the receiving bodies have an accepting space suitable for the fixing of at least some of the light-transmitting fibres and a transmitting body that allows light to pass through it, the basic bundle and the signalling bundle are arranged in the cable sheath and the one end and the other end of the basic bundle are each fixed in the accepting space of a receiving body in such a way so that they can not move, one end of the basic bundle is fitted to the transmitting body of one of the receiving bodies and the other end of the basic bundle is fitted to the transmitting body of the other receiving body. The characteristic feature of the invention is that one end (21) of the signalling bundle (20) is fixed in the vicinity of the one end (11) of the basic bundle so as to prevent light input, while the other end (22) of the signalling bundle (20) is clamped into the light-transmitting output member (60) in the vicinity of the other end (12) of the basic bundle (10).
