Abstract: The invention relates to a rotation transformer for a cable connection, one end of said cable (4) executing a limited number of revolutions in relation to the other end, about a longitudinal axis (1), whilst maintaining an uninterrupted connection between both ends. The longitudinal axis (1) comprises separation discs (3). Known rotation transformers of this type have an extremely complex technical construction. The aim of the invention is to configure a rotation transformer in such a way that it can be produced simply and cost-effectively. To achieve this, the distance between the rotatable separation discs (3) is measured in such a way that a maximum two coils of the cable (4) lie on only one plane between two separation discs (3), that the cable (4) is guided through said discs without converging and that it is fixed and wound alternately from the outer diameter to the longitudinal axis (1) and vice versa between the pairs of separation discs (3).

Abstract: A device for inductively transmitting electrical energy to at least one mobile load, with at least one primary conductor that extends along a designated path of the load in the form of a conductor loop and from which a secondary conductor arranged on the load is able to draw electrical energy. At least two conductor loops are provided that are electrically separated from one another and respectively assigned to different segments of the path. The conductor loops are arranged relative to one another so that electrical energy intended for the load can be transmitted from a first conductor loop to at least a second conductor loop due to inductive coupling between the conductor loops. A section of the second conductor loop that is inductively coupled contains a larger number of windings than that of the first conductor loop. The second conductor loop includes of a series of partial loops that extend parallel to one another.

Abstract: A device for supplying a consumer displaceable alongside a compressed air line (1) with compressed air. The compressed air line (1) presents a lateral slit (2) through which a hollow flexible tube (10, 10A), which is joined to the consumer, protrudes into the compressed air line (1) and the slit (2) is sealed off from the surroundings by an elastic sealing tape (3, 3A) which in the area of the flexible tube (10, 10A) is deformed by same to avoid pressure losses to the surroundings. The flexible tube (10, 10A) opens into a pipe section (11) which can be displaced inside the compressed air line (1) and its ends are sealed in relation to the walls of the compressed air line (1), and the distance between the seals (12, 13) is greater than the area of the sealing tape (3, 3A) deformed by the flexible tube (10, 10A).

Abstract: An energy transmission device allows several consumers to be supplied with energy independent of one another and provides contactless transmission of energy from a primary current line, through which alternating current flows, to a number of secondary, resident load circuits with at least one coil, each of which draws energy from the electromagnetic field of the current lead. An auxiliary line runs parallel to the current lead and it is connected with the current lead via several connecting points in order to conduct current from a first connecting point via the auxiliary line to a second connecting point. In at least one section of the line, between two connecting points, an adjustable impedance is provided in the auxiliary line which is controlled by a monitoring device in order to prevent blocking of the line by a disconnected consumer.

Abstract: A work station feeding module with a rail includes a carriage guided thereon and movable along the rail. The work station feeding module includes at least one supply line guided in a flexible energy supply chain arranged within the rail. One end of the flexible energy supply chain is fixed with respect to the rail and the other end is fastened on the carriage. Such work station feeding modules have the disadvantage that only electric lines can be guided in such modules and additional feeding devices must be provided for other energy carriers or raw materials. The work station feeding module enables a simpler and more compact feeding of the work station and guarantees that at least one of the supply lines is a compressed-air line. A compressed-air outlet connection is provided on the carriage. The module has a continuous compressed-air channel in its longitudinal direction that is connected to the rail-fixed end of the compressed-air line through an output branch.

Abstract: A safety strip for use on moving devices with the danger of pinching has a plurality of contact elements assembled into a row under an axial prestress along the safety strip. Extending in these contact elements are electrically conductive contact pins that, in the off, i.e. non-operate state maintain a circuit through the adjacent contact elements by contact and in the event that the safety strip is deformed through some external force open the circuit through the spatial distance from each other. The axial prestress and control of the individual contact elements is effected by means of an elastic tubing. However, in the present state-of-the-art, such safety strips result in a high material load in the area of the contact zones between the individual contact elements and, in addition, have only a limited maintainability.
