In a known method for the production of a blank mold for optical fibers, a fluorine-doped SiO2 enveloping glass is produced on a core glass cylinder that rotates about its longitudinal axis, wherein a silicon-containing starting substance is fed to a plasma burner, said substance is then oxidized in a plasma flame assigned to the plasma burner to obtain SiO2 particles, the SiO2 particles are deposited by layers on the enveloping surface of the cylinder of the core glass cylinder in the presence of fluorine and sintered into the enveloping glass. The invention aims at providing an economical method, which builds upon the above-mentioned method, in order to produce a blank mold from which optical multi-mode fibers (52) can be obtained. In comparison with fibers (51) produced according to standard methods, said optical multi-mode fibers are characterized by high initial transmission in the UV wavelength range and good resistance with respect to brief UV radiation, more particularly in the 210-300 nm wavelength range. According to the invention, a plasma flame that irradiates an ultraviolet light having a wavelength of 214 nm with an intensity of at least 0.9 μW—determined on the basis of plasma flame intensity measurement—is used for the formation and deposition of the SiO2 particles on the core glass.

A skin-friendly hook component of a hook and loop fastener that reduces or eliminates the occurrence of red-marking and/or irritation if brought into contact with a wearer's skin. In one embodiment, the hook component can have a relatively large top surface area among the hooks with respect to a surface area of the hook backing. In another embodiment, the hook backing is highly flexible, attributable to a flexible resin and/or modified topography. In yet another embodiment, a highly flexible polymer, or polymers, can be used to make individual hooks such that the hooks bend in response to a minimum amount of pressure. Various illustrated hook tapes have features along their edges to enhance skin-friendliness. A skin-friendly hook component results any combination of the disclosed embodiments. The hook component is particularly beneficial when used in absorbent articles.

Pneumatic single grain sowing machine having a seeds storage container, and an individualization device subjected to air pressure, exhibiting perforations and rotating. The individualization device is led with its region disposed below the rotation axis at least in part to the placing of seed grains at the perforations through a seed storage led from the storage container to the individualization device. A separating wall is disposed between the storage container and the individualization device and determining the seed storage height level and extending at a distance to the individualization device in a vertical direction. In order to furnish a single grain sowing machine wherein the part segments with thereon disposed storage containers and individualization devices can be pivoted by 90 degrees around the horizontally running swivel axis, an adjustably formed blocking device is disposed between the individualization device and the separating wall in the region of the lower end of the separating wall and above the seed storage height level, wherein the blocking device closes in the intermediate space between the individualization device and the separating wall.
摘要:
A method for interchanging information data between an electrical load and an item of equipment arranged between the load and the electric power grid is disclosed. An energy storage device located in a load recognition unit associated with the load is charged during a load recognition phase at start-up of the load. After the energy storage device is charged, data stored in the load recognition unit are repeatedly transmitted in form of a data burst to the item of equipment located between the load and the electric power grid. The data burst includes a preamble and load data; whereby the transmission is controlled by a controller in the load recognition unit.
