20130299297 | Switchable Coupling - A switchable coupling with a coupling system between a driving element and an output element is provided. The switchable coupling includes an actuator, an elastic actuating element and a switching element movable between starting, central and end positions. In the central position the switchable coupling has a different state (open or closed) than in the starting position. The switchable coupling further includes a bolt constrained between first and second bolt stops. Axial movement of the switching element causes operative surfaces connected to the switching element or the bolt to engage with elements on other of the switching element and the bolt, such that the bolt rotates relative to the switching element. The bolt alternately moves relative to the switching element into a first relative position blocking switching element movement in the central position, and into a second relative position permitting movement of the switching element toward the starting position. | 11-14-2013 |
20130299296 | Switchable Coupling, in Particular for Passenger Vehicle Auxiliary Assemblies - A switchable coupling, in particular for vehicle auxiliary assemblies, is provided. The coupling includes an actuating system actuated electrically, mechanically, pneumatically or hydraulically between a driving element and an output element, and a switching element movable between switching start and end positions counter to the force of one or more resetting elements upon actuation of the actuating system. In the end position, the switching element connects the driving and output elements such that the output element and an auxiliary coupling connected thereto rotate with the driving element. After deactuation, locking bodies located on the auxiliary coupling produce an connection between the driving and output elements which continues to conduct torque between the driving and output elements. The connection is interrupted only when the rotational speed of the driving element falls below a limit value. The coupling does not require a permanent supply of power in the open or closed state. | 11-14-2013 |
20130255812 | FLUIDIC ACTOR COMPRISING DEFORMABLE SEAL ARRANGEMENT AND LONG STORABILITY - A fluidic actuator includes a basic arrangement having at least one cavity formed therein, an activatable substance within the cavity, and a deformable seal arrangement. The activatable substance, exemplarily an electrolyte, may be converted, at least partly, by suitable activation and thus cause a change in pressure in the cavity. The deformable seal arrangement serves for sealing the cavity. The seal arrangement includes an element containing paraffin and may be deformed when activating the activatable substance due to the change in pressure of the activatable substance. A corresponding method of manufacturing includes the following steps: providing the basic arrangement; forming a cavity, which is open on at least one side, in the basic arrangement; introducing the activatable substance into the cavity; and sealing the cavity using the deformable seal arrangement which includes an element containing paraffin. | 10-03-2013 |
20130062768 | METHOD FOR THE PRODUCTION OF A SUBSTRATE HAVING A COATING COMPRISING COPPER, AND COATED SUBSTRATE AND DEVICE PREPARED BY THIS METHOD - A method for producing a substrate with a copper or a copper-containing coating is disclosed. The method comprises a first step wherein a first precursor, a second precursor and a substrate are provided. The first precursor is a copper complex that contains no fluorine and the second precursor is selected from a ruthenium complex, a nickel complex, a palladium complex or mixtures thereof. In the second step, a layer is deposited at least on partial regions of a surface of the substrate by using the first precursor and the second precursor by means of atomic layer deposition (ALD). The molar ratio of the first precursor:second precursor used for the ALD extends from 90:10 to 99.99:0.01. The obtained layer contains copper and at least one of ruthenium, nickel and palladium. Finally, a reduction is performed step in which a reducing agent acts on the substrate obtained after depositing the copper-containing layer. | 03-14-2013 |
