    摘要: A tissue punch for removing tissue parts from the human or animal body is described, which comprises the actual operating instrument, as well as a separate driving unit, which is connected by means of a flexible force transmission member to the operating instrument. The operating instrument comprises a surgeon-guided outer tube and an inner tube slidably arranged therein having a cutting edge for separating the tissue parts. The inner tube is also supplied with a vacuum by means of a hose connection for removing a separated tissue part from said inner tube. The operation of the inner tube or the cutting edge connected thereto, as well as the suction are controlled by a separate control unit.

    摘要: Photosensitive recording elements which possess a photosensitive recording layer which is applied to a dimensionally stable base, if necessary via one or more intermediate layers, and have good photochemical properties and a long shelf life contain a compound of the general formula (I) ##STR1## where M is a hydrogen atom or proton, an alkali metal cation, the ammonium cation or an amine cation and R.sup.1 and R.sup.2 are identical or different and are each a substituted s-triazine ring, in the photosensitive recording layer and/or any intermediate layer present, in order to control the photochemical properties.

    摘要: An electrophotographic recording material contains, as charge carrier-transporting compounds in the photoconductor layer, a mixture of one or more compounds of the formula ##STR1## and one or more compounds of the formula ##STR2## in a ratio of from 9:1 to 0.6:1, preferably from 2.3:1 to 0.8:1. In the formulae, R.sup.1 and R.sup.2 independently of one another are each alkyl, allyl, phenylalkyl or unsubstituted or substituted phenyl, R.sup.3 and R.sup.4 independently of one another are each hydrogen, alkyl, alkoxy or halogen, and R.sup.6, R.sup.7, R.sup.8 and R.sup.9 independently of one another are each alkyl, phenylalkyl or cyclohexyl.When the mixture of (I) and (II) is present in an appropriate concentration, the recording materials are highly photosensitive, although the problems usually encounted in the case of high concentrations of charge carrier-transporting compounds do not arise.
