Abstract: To prevent elongation of a covering tape or ribbon (25) extending over an elongated opening (34) in an elongated base body (2) over which a movable element (3) can slide, the tape or ribbon is retained at preferably both of its ends, by a reverse motion, or one-way lock (50,52). In the simplest form, this reverse-motion lock (50,52) is formed by a leaf spring (63) extending at an acute angle with respect to the tape or ribbon; the tape or ribbon is backed up by bridge-like counter element (54) bridging over the elongated opening (34).

Abstract: 3-chloropropylsilanes are prepared from hydrogensilanes and allyl chloride, where a stoichiometric excess of allyl chloride is maintained in the condensate of the vapor emitted by the boiling reactant mixture.

Abstract: The manufacture of vinyltrichlorosilane by reacting vinylchloride with trichlorosilane at a temperature of 400.degree. to 750.degree. C. in a tubular reactor with a rotating displacement body axial-symmetrically disposed therein is improved by heating the reactants to a temperature of 120.degree. to 400.degree. C. prior to their introduction into the reactor.

Abstract: 3-sulfonyl-3,7-diazabicyclo[3,3,1]nonane compounds corresponding to the formula: ##STR1## wherein R.sup.1 is alkyl, cycloalkylalkyl or benzyl,R.sup.2 is hydrogen or lower alkyl,R.sup.3 is hydrogen or lower alkyl orR.sup.2 and R.sup.3 together form an alkylene chain, andR.sup.4 represents lower alkyl, thienyl, halogen substituted thienyl or a --(CH.sub.2).sub.n --R.sup.5 group, wherein n=0-3 andR.sup.5 is an optionally substituted phenyl group.The compounds are pharmacologically active, particularly in influencing the motility of the stomach.

Abstract: 3,7-Diazabicyclo[3,3,1]nonane compounds having valuable heart rate-affecting pharmacological properties corresponding to the Formula I: ##STR1## wherein R.sup.1 is alkyl, cycloalkylalkyl or benzyl,R.sup.2 is lower alkyl,R.sup.3 is lower alkyl, orR.sup.2 and R.sup.3 together form an alkylene chain, andR.sup.4 represents a benzhydryl group, optionally substituted by halogen, lower alkoxy, lower alkyl, hydroxy or trifluoromethyl, or a cinnamyl group optionally substituted by halogen, lower alkyl, lower alkoxy, hydroxy, nitro or trifluoromethyl.

Abstract: Compounds of Formula (I)S--(CH.sub.2).sub.n --A (I)in whichS is a 17-spartein nucleusn is 0 or 1and A is 2-furyl, 2-thienyl or 2-(N-alkyl)pyrryl when n=0, or 3-furyl or 3-thienyl when n=1, or pyridyl or a phenyl group of Formula (II) ##STR1## in which at least one of R.sub.1, R.sub.2 and R.sub.3 is a defined substituent other than hydrogen. Such compounds and corresponding compounds in which A is an unsubstituted phenyl group are useful in pharmaceutical compositions as heart affecting agents. Methods of preparing such compounds and pharmaceutical compositions are also disclosed.
