  • Patent number: 5950974
    Abstract: An apparatus for fastening and wiring of a plurality of electrical units, particularly in a switchgear cabinet.

  • Patent number: 5831216
    Abstract: A profile strip of insulating material is proposed for holding many electrical cables (27)-(30) in switching and control boards and panels, which consists of a mounting section (13) for fastening on a mounting track and a comb-like cable holding section (15) formed thereon. This cable holding section (15) consists of many parallel teeth (14), between which insertion slits (26) for insertion or installation of electrical cables are formed. The insertion slits (26) are limited at the sides by elastic tabs (21) formed on the teeth (14). Between every two teeth (14) a shorter intermediate tooth (20) is positioned such that it divides a portion of the insertion slit (26) into two narrower partial slits. This permits the elastic tabs (21) to hold, in variable fashion, not only cables of smaller diameter (29) in the portion with the intermediate tooth, but also cables of larger diameter (27), (28) in the remaining portion.

    Abstract: A workbench, in particular for welding and structural steel work, includes a frame assembly having opposing axial ends and including a pair of traverses respectively disposed at the axial ends, and a pair of spaced substantially parallel platforms for forming working surfaces for installation and placement of workpieces, with the working surfaces being expandable in all directions by retractable or detachably secured elements. One of the platforms is stationarily fixed on the traverses and the other one of the platforms is movably supported on the traverses for displacement in direction of the stationary platform. Extending laterally of the stationary platform is a support unit for attachment of accessories and including at least one support and a guide bar secured to the frame assembly and configured of polyhedral cross section for guiding the support in longitudinal direction.

  • Patent number: 5630227
    Abstract: A satellite receiver is provided which downconverts an incoming band of signals received at a carrier frequency to a signal spectrum centered about an intermediate frequency (IF). The IF signal spectrum is filtered to provide a group of signals therefrom. The group comprises a subset of all the signals in the incoming band of signals. The group of signals from the IF signal spectrum is sampled at a high frequency which is greater than the highest frequency present in the group but lower than the intermediate frequency, in order to provide the group of signals at baseband directly from the IF signal spectrum.

  • Patent number: 5608800
    Abstract: 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.
