    摘要： To provide directionally dependent attenuation for an optical information transmission link using simple means without the use of an active component, it is proposed to couple two optical waveguides (1, 2) having different core diameters to one another, the core diameter of the second fiber (2) being at least six times greater than the core diameter of the first fiber (1). In this manner, it is achieved that the conduction of light signals in a predefined direction is attenuated by at least the factor 30, while, on the other hand, the light propagating in the reverse direction, is attenuated very slightly.

    摘要： A device for separating flat parcels from a stack of parcels includes a drawing element that travels in a conveying direction and acts by friction on a parcel to be drawn off from the stack of parcels. A guide wall for the stacked parcels forms a gap with the drawing element for a drawn off parcel to pass through. A support surface supports the stack of parcels and generates a stack pressure in a direction of the drawing element. At least one first nozzle disposed in the region of the support surface, and/or the region of the guide wall, blows compressed air between the parcels in the stack. At least one second nozzle, disposed in the region of the gap, between the stack of parcels and the guide wall, blows compressed air having a predetermined inclination counter to the conveying direction of the parcels to be drawn off.

    摘要： A letter sorting system includes a row of juxtaposed stack compartments; a material intake device arranged along and spaced from the compartments; a carriage arranged for travel along the compartments; and a transfer bridge mounted on the carriage to be displaced thereby along the compartments. The transfer bridge includes an exterior frame pivotally attached to the carriage for pivotal motions into first and second positions; an interior frame pivotally attached to the exterior frame for pivotal motions into first and second positions; and a slide having a first part attached to the interior frame and a second part attached to the exterior frame. Dependent upon simultaneous positions of the exterior and interior frames, the transfer bridge may assume first, second and third operating positions. In the first operating position sliding surfaces of the first and second parts of the slide form a continuous, upwardly facing surface for guiding material thereon between a selected compartment and the material intake device. In the second operating position a part of the interior frame is oriented upwardly and is adapted to accommodate a container thereon; and in the third operating position the first and second parts of the slide are substantially in a vertical orientation.

    摘要： The present invention refers to a sealing element, particularly for the sealing of joints, having a foam element which is elastically expandable with delay as a result of impregnation and a substantially air-tight cover. In order to obtain improved tightness of the seal while retaining the advantageous ability of use of such a sealing element, the cover forms an open region within which the foam element is exposed.

    摘要： In apparatus for the separate discharge of flat items from a stack of such items, which apparatus includes a movable support for supporting the stack of items, a withdrawal mechanism mounted to engage the foremost item in the stack and withdraw that item from the stack, a supporting wall manually movable into an initial position for supporting the trailing end of the stack, and a drive system connected to drive the supporting wall toward the withdrawal mechanism under control of the state of a switch actuated in dependence upon the force being exerted by the stack on the withdrawal mechanism, resilient force equalizing elements are provided between the drive system and the supporting wall in drive transmitting relation therebetween, and are constructed and mounted for permitting advancing movement of the supporting wall to lag behind that corresponding to the sum of the drive movements produced by the drive system whenever the pressing force between the supporting wall and the stack exceeds a given value.
