摘要： An apparatus for fastening and wiring of a plurality of electrical units, particularly in a switchgear cabinet. At least one mounting crosspiece (12-15) accommodating the electrical units on its mounting side can be fastened to at least two bearing rails (10, 11) arranged vertically and behind them, fasteners for fastening the electrical units on the mounting crosspiece (12-15) being provided. This mounting crosspiece (12-15) shaped like a flat strip has, on its rear side opposite the mounting side (29), an integrally formed holding rib (28) extending over its length and having a mounting groove (30) open toward the mounting side (30) designed for accommodating the heads (33) of mounting screws (34) for fastening the mounting crosspiece (12-15) by means of the holding rib (28) on the bearing rails (10, 11). At least one of the two opposite longitudinal edges of the mounting crosspiece (12-15) shaped like a flat strip can be provided with a wiring comb (39). This makes it possible to achieve a very small constructional depth and reduce the number of mounting parts at the same time, the space behind the mounting crosspiece being almost completely usable as wiring space.

摘要： The process is intended to establish whether the data transmitted by the transmitter (SE) to the receiver (EM) have been tapped and spuriously reintroduced at a later point in time and/or have been inadmissibly altered. For this purpose, the signature (S) assigned to the useful data (D) is enciphered symmetrically, using a combination of coupling data (K), characterizing the coupling between transmitter and receiver, and random data (Z), generated by a random generator. The coupling data are transmitted in plain text, the random data are enciphered. On the receiver side it can be established whether the transmitted message has been tapped and reintroduced at a later point in time if the coupling data are inadmissible. An alteration of the transmitted message can be established from ascertaining that the key used for enciphering the signature, obtained from the combination of coupling data and random data with the aid of a one-way function, does not correspond to the key obtained during deciphering at the receiver and consequently the deciphering of the enciphered signature leads to an incorrect result. The incorrect signature is detected during verification of the signature.

摘要： The invention relates to a novel photosensitive recording material which can be developed in aqueous solvents after its imagewise irradiation with actinic light and which consists essentially of a dimensionally stable base (A) and of a photosensitive recording layer (B). The said photosensitive recording layer (B) contains from about 48 to about 85% by weight, based on the photosensitive recording layer (B) of one or more elastomeric graft copolymers (B1) which are selected from the group consisting of polyalkylene oxide - vinyl ester - graft copolymers whose vinyl ester structural units have been hydrolyzed to a degree of not less 50 mol.-% from about 0.01 to about 10% by weight, based on the photosensitive recording layer (B), of one or more photoinitiators (B2), and from about 5 to about 30% by weight, based on the photosensitive recording layer (B), of one or more photopolymerizable monomers (B3). In addition to these components, the photosensitive recording layer (B) might contain further assistants or additives. The novel photosensitive recording material is especially well suited for the production of lithographic printing plates, resists and relief plates, in particular relief printing plates. The invention is furthermore related to a process for preparing the novel photosensitive recording material by polymerizing vinylesters in the presence of polyalkylene oxides to yield polyalkylene oxide - vinylester - graft copolymers, hydrolyzing or transesterifying said polyalkylene oxide - vinylester - graft copolymers to yield the said elastomeric graft copolymer (B1), mixing the said elastomeric graft copolymers (B1) with the other components of the photosensitive recording layer (B), and forming the said photosensitive recording layer (B) from the mixture consisting of its components on the dimensionally stable base (A).

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.
