  • Patent number: 9103243
    Abstract: The invention relates to a valve train for gas exchange valves of an internal combustion engine, having a base camshaft, a plurality of cam carriers, which are arranged in a rotationally fixed and axially movable way on the base camshaft, as well as stopping devices for retaining the cam carriers in defined displacement positions along the base camshaft, with the stopping devices comprising in each case a pressure-applying element, which is inserted into a recess of the base camshaft and pressed in the radial direction of the base camshaft against an opposite inner circumferential section of the cam carrier. In order to counteract noise generation in the valve train, a first variant of the invention provides an additional pressure-applying element at an axial distance from the pressure-applying element. This additional pressure-applying element is pressed against an opposite inner circumferential section of the cam carrier.

  • Publication number: 20130107501
    Abstract: The suspension device for presenting goods comprises a profile rail (1), into which an electrical profiled element (2) is inserted, through which electrical conductors (21) partially embedded in insulation (20) extend. The electrical conductors are accessible via a passage (10) of the profile rail (1) that opens to the outside. A primary support (4) that can be hung in the profile rail (1) has an insertion section (416,426) that can be inserted into the passage (10). An adapter (5) is arranged on the insertion section (416) of the primary support (4). Said adapter is designed to tap current on the electrical conductors (21) in order to operate a lighting unit (7). An electrical supply line (6) extends from the adapter (5) to the lighting unit (7). The adapter (5) has a housing (52) and a current collector (54) having contacts (541), which are intended to tap current on the electrical conductors (21).

  • Publication number: 20130098855
    Abstract: The invention relates to the device for displaying articles, comprising a mounting (2) which has an internal cavity (25) with a cavity opening (250) and which is intended for fixing on a supporting structure (9). The device also comprises a primary support (3) which has an end piece (30) that is designed complementary to the cavity (25) and which is intended to be hooked into the mounting (2) in the cavity (25) in a stationary manner with the end piece (30) inserted through the cavity opening (250). The configuration of the end piece (30) on the primary support (3) and of the cavity (25) in the mounting (2) requires that the end piece (30) is inserted into the cavity opening (250) in an end piece (30) position that is inclined relative to the horizontal with the free end of the end piece (30) being lowered. When the intended hooked end position between the primary support (3) and the mounting (2) is achieved, the end piece (30) is inserted into the cavity (25) to the maximum depth.
