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: An apparatus for winding and unwinding cables has at least two rotatable drums. At least one cable can be wound onto or unwound from each of these drums. The drums are connected by a coupling linkage such that both the drums either wind or unwind the respective cables simultaneously. An arrangement cooperating with the coupling linkage effects winding of the unwound cables.

Abstract: A medical system with adjustable, movable components that can be set by disengageable brakes, in particular an X-ray diagnostic apparatus with a C-arm that can be adjusted in the height of its orbital position and angulation and that carries an X-ray source and a beam receiver at its ends, has a sterilizeable handle that can be plugged in various positions, with a plug lock. A disengage button for the system brakes is arranged on the handle, which can be engaged with switching apparatuses in the system upon plugging the handle into a component of the system. The button can then be operated for actuating and disengaging the brakes.

Abstract: A medical apparatus has a C-arm which carries a radiation transmitter, and which is adjustably held by a mount so as to be movable along the circumference of the C-arm. The mount engages guideways which are provided at a rear side of the C-arm. The C-arm is in the form of a hollow, profiled part having a substantially U-shaped cross-section. The guideways are respectively disposed at the insides of the legs of the U-shaped cross-section. The C-arm has an interior channel therein with a rectangular cross-section, which is adapted for accepting electrical leads or supply lines for the radiation transmitter. The channel is laterally adjacent one leg of the U-shaped cross-section.

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 light distributor for use in an X-ray diagnostics installation wherein a light image corresponding to an X-ray image is generated by an X-ray image intensifier, and the light image is to be recorded using a number of different image recorders as a housing with input optics facing toward the X-ray image intensifier for generating a parallel light beam path, and has at least two movable mirror surfaces secured flat on a carriage. The carriage and mirror surfaces are arangement obliquely in a plane which is parallel to the beam path, and the carriage is displaceable along guides within this plane so that one of the mirror surfaces can be laterally moved into the beam path to deflect the light from the image intensifier onto a desired image recorder. At least one of the mirror surfaces is partially reflecting.

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 being treated with magnesium or with both magnesium and 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 magnesium-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 surfade and at a rate which is less than the maximum rate at which the magnesium-containing substance is capable of reacting with the melt.

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).

Abstract: A steel melt is confined and subjected to a partial vacuum. A particulate additive is entrained by a neutral nonreactive carrier gas and introduced into the melt below the surface thereof at a depth such that the additive is immediately vaporized and rises toward the surface of the melt in the form of bubbles which react with components of the melt. With particulate calcium as the additive an injection depth 1500 mm, a temperature of approximately 1500.degree.C, and a vacuum of 20 Torr allows the sulfur content of a steel melt readily to be reduced below 0.005% by weight.
