Abstract: 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.

Abstract: In a method for producing graded-index profiles in polymeric optical fibers, ionizing radiation is used to cause an increase in the refractive index, for example in PMMA. Polymeric optical fibers, preforms or fiber-core preforms are irradiated with ionizing radiation of predetermined wavelength and dose while being moved past the radiation source in the longitudinal direction at a given speed and are subsequently tempered for a defined length of time. Through the control of the spatial distribution of the ionizing radiation with the aid of mirrors, lenses or aperture systems, a uniform, radial graded-index profile is produced over the entire fiber length, so that the polymeric fiber, used as an optical waveguide, has improved transmission characteristics for optical signals.

Abstract: A device for intermediate stacking of letters (SE) with a stacking roller (SR), stacking carriage (SW), underlying belt (UB) and a separation device. The stacking roller (SR) is mounted on the stacking carriage (SW) and a pressure gauge is provided in the vicinity of the stacking roller to measure the pressure of the stack against the pressure gauge. A device is provided for detecting possible slants in the letter stack (ST); that where such a slant is detected, the stacking carriage (SW) and/or underlying belt (UB) are made to move until the slant is eliminated; that the stacking carriage (SW) should be displaced along the underlying belt (UB) until the letter stack (ST) exerts a certain pressure on the pressure gauge provided that the detecting device does not report the presence of a slant.

Abstract: A device for radially deflecting consignments in transport plants permits consignments to be conveyed, in linear sections, clamped between an upper belt and a lower belt, where the upper belt urges the inner side of the curvature of the consignments to be conveyed against a surface profile of the deflection device. The deflection device on which the inner side of the curvature of the consignment rests has a surface profile with depressions on the side facing the consignment. The tangential length of the surface profile is at least as long as the outside of the respective consignment.

Abstract: An optical branching element has an input waveguide (10) and a plurality of output waveguides (20a, 20b), which are so disposed at a distance from the input waveguide (10) that a beam of light launched into the input waveguide (10) over a coupling path of a predefined length couples over with a defined intensity into the output waveguides (20a, 20b).

Abstract: 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.

Abstract: The hoppers of several dust precipitators are connected to a common readily accessible monitoring station by discrete conduits each of which has a first open end at a preselected level in the respective hopper, a second open end at the monitoring station and an intermediate portion extending above the corresponding preselected level. Suction which normally prevails in the hoppers tends to maintain closed pivotable flaps for the second open ends of the conduits. If the dust in a hopper accumulates to or rises above the respective preselected level, the corresponding flap is opened by a counterweight and such movement of the flap entails the generation of a signal which is used to evacuate dust from the corresponding hopper and/or to actuate an alarm for the convenience and attention of the persons in charge.

Abstract: A singling apparatus for letters, vouchers, receipts, checks, punched cards, or other main items of all kinds up to a given size and thickness, singles out the items arriving in any irregular sequence one below the other, unarranged and oriented on a longitudinal or transverse edge. To obtain a high singling output and draw-off quality, the items are transported in vertical position through a transport mechanism and, by using a restricting guiding unit, into the draw-off region of a draw-off belt revolving about deflection bodies tangentially toward the draw-off belt surface. In the contact zone of draw-off belt and one deflection body the inflowing mail items are pressed against the draw-off belt and only the items coming into contact with the draw-off belt directly are drawn off by friction, by deflection of these items around the deflection body.
