An apparatus is provided for processing audio and/or video data comprising a module for displaying an element that has a shape of at least a portion of an analogue clock, wherein a sector associated with the element indicates a duration or a length of the audio and/or video data.
Abstract:
The invention relates to a network node and to a method for adding a network node or an exchange in a communication network which may have the same signaling point code as another exchange in the communication network. Two internal local networks are established in an exchange of the telecommunication network and one signaling link is established from the second internal logical network to another exchange of the telecommunication network, via which all signaling of the other exchange is carried out. The invention is further characterized in that both exchanges use the same signaling point code.
Abstract:
Dyestuffs of the formula ##STR1## are used for coloring organic solvents, mineral oil products, waxes, plastics and surface coatings, wherein R is alkyl having 1 to 7 carbon atoms, R.sup.1 is alkyl having 1 to 8 carbon atoms or alkenyl having 3 or 4 carbon atoms, and R.sup.2 is hydrogen, alkyl having 1 to 8 carbon atoms or alkenyl having 3 or 4 carbon atoms.
Abstract:
A process for the production of steel with increased ductility in which a sulfur-containing steel melt is deoxidized and, if desired, is supplied with alloying elements, the deoxidized melt is treated with calcium as part of a purification action simultaneously reducing the sulfur content and the reaction is carried out in a casting ladle having a lining free from siliceous oxides. The melt is covered with a synthetic slag free from siliceous oxides and the calcium-containing substance is introduced in fine-grain particulate form into the melt in a carrier gas at a level at least 2000 mm below the melt surface and at a rate which is less than the maximum rate at which the calcium-containing substance is capable of reacting with the melt.
Abstract:
A process for working up alkaline process wastewater from the nitration of aromatic compounds to mono-, di- and trinitroaromatics with a pH of 7.5 to 13 or a mixture W with a pH of 6 to 10 of alkaline process wastewater and the aqueous distillate of the sulfuric acid concentration, comprising the steps of a) acidifying the alkaline process wastewater or the mixture W by adding concentrated sulfuric acid which originates from the workup of the aqueous, sulfuric acid-containing phase obtained in the nitration to a pH below 2, which forms a mixture A consisting of organic phase which separates out and acidic aqueous phase, and b) extracting the mixture A with an aromatic extractant.

Abstract:
A light distributor for an x-ray diagnostics installation has mirror-symmetrically disposed sets of light exit ports at a housing, which are adapted for connection to various different image recording components. Inside the housing, a mirror system is provided which can be arranged in a first position or a second position. When the system is arranged in the first position, light is directed from an input port of the light distributor to a first of the sets of light exit ports in the housing. When the mirror system is arranged in the second position, light from the input port is directed to a second of the sets of light exit ports. The mirror system can be changed between the first and second positions by a simple manual operation, using the same mirrors and the same mirror mounts, which are interchangeably accepted in a single set of mounting locations in the housing.
Abstract:
A process for making a steel melt for continuous casting in which the steel melt is formed in a smelting unit under an iron-oxide-containing slag which is held back while the steel melt is tapped and subjected to deoxidation with silicon or aluminum. The sulfur-containing deoxidized melt is then subjected to an aftertreatment with a calcium-containing substance, especially calcium-silicon or calcium carbide in a covered ladle with a silica-free lining after the steel melt is covered with a synthetic slag formed from pulverulent lime and 10 to 30% of a silica-free fluorite and/or alumina fluxing agent which does not release oxygen to the melt. The calcium-containing substance is introduced in an amount which is greater than that required for desulfurization and/or establishing the viscosity of the melt, at a depth of at least 2000 mm and about 300 mm above the bottom of the ladle in a neutral carrier gas (e.g. argon).
