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.

摘要： A multi-layer element contains a photosensitive layer composed of a mixture of an elastomeric polymer as a binder, a photopolymerizable monomer and a photopolymerization initiator, the photosensitive layer being bonded to a polyester base via an adhesive layer. The adhesive layer is composed of a reaction product, which is insoluble in the process solvents, of a hardenable cellulose ether and a polyisocyanate. The multi-layer element is particularly suitable for the production of printing plates and relief plates, and can be produced by applying a layer of an adhesive, which contains the hardenable cellulose ether and the polyisocyanate, to the polyester base, baking the adhesive to form the insoluble adhesive layer, and applying the photosensitive layer.

摘要： A device for counterbalancing a swivelable body part on a motor vehicle, especially a trunk lid on an automobile, said device including a hinge for the swivelable body part and a torsion bar, the torsion bar being bent to form a crank in the vicinity of a movable hinge part. An intermediate lever is articulated on the movable hinge part and engages the crank, the crank including a crank pin between two legs, the legs being connected by arcuate segments both with the crank pin and with the torsion bar. The legs are made S-shaped so as to minimize waste, provide ease of manufacture and small installation space requirements for the crank.

摘要： After a key pair with a public key and a corresponding private key has been determined on the basis of an initial value, the initial value is made available to a user. The private key can then be erased. When the user wishes to carry out a cryptographic operation based on the “Public-Key-Technology”, the user enters the initial value into a computer and, upon utilization of the initial value, a regenerated private key is formed, which corresponds to the private key that had been previously formed but was then erased.
摘要翻译：在基于初始值确定具有公开密钥和相应私钥的密钥对之后，初始值对用户可用。私钥可以被擦除。当用户希望基于“公共密钥技术”执行加密操作时，用户将初始值输入到计算机中，并且在使用初始值时，形成再生的私钥，其对应于以前形成但被删除的私钥。
