Adjacent lying plug-connector halves, the front ends of which exhibit pin or sleeve shaped plug elements, are provided with first and second supporting bodies, of which the first supporting body, with a sleeve shaped plug element, may be connected by means of a joinable groove-tenon-interconnect lying crosswise to the plug insertion direction, and exhibits an entrance channel for a plug connector half with a pin shaped plug element. The second supporting body with a concentric guiding tube for the insertion of pin shaped plug elements from both directions exhibits a tenon-groove-interlock contour at both ends that matches that of a sleeve shaped plug element. The first supporting body can therefore be interlocked with second supporting bodies or sleeve shaped plug elements at choice, whereby light wave guides single or double plugs may be connected to transmit- and/or receive modules and light wave guides single or double plugs may be inter-connected.

In the method according to the invention for operating a cement plant, the raw meal is preheated in a preheating zone, the preheated material is precalcined in a calcining zone and the precalcined material is finally sintered in a sintering zone. The cement plant is operated in such a manner that the precalcined material which is supplied to the sintering zone has an SO3 concentration of at least 5.5% by mass and a CaSO4 proportion of at least 75%, preferably 90%, of the total salt content.

A mode filter for connecting two electromagnetic waveguides with different cross-sections includes a tubular section (4) with openings at both ends. The cross-sections of the openings match the cross-sections of the two different waveguides, while the interior space (11) of the tubular section (4) transitions from one cross-sectional shape into the other cross-sectional shape. Undesirable modes of the electromagnetic waves which are to be transmitted, are minimized by flat elements (14, 15) protruding radially inwardly into the transition region and extending axially along the tubular section (4). The flat elements (14, 15) are made of a material with a high electrical conductivity. The elements (14, 15) are arranged diametrically opposed from each other and aligned in the same plane and separated by a gap (16). The axial length of the flat elements is short in relation to the length of the tubular section (4). The length of the flat elements in the axial direction and the spacing (A) between them is dimensioned so as to minimize the ripple in the group velocity and the amplitude of the wave to be transmitted. The ripple is caused by the superposition of the excited modes.

A process and a device for substantially eliminating tolerance-dependent variations of a preselectable space between the components of an optical communication apparatus is described. U-shaped recesses are provided in a metal casing for pressing in flange-type necks of, for example, optical transmitting and receiving devices. The parallel arranged devices are so spaced from each other that they are not subject to tolerance-dependent variations. For this purpose the metallic necks are coated with a plastic layer, and ribs provided at the lateral walls of the U-shaped recesses dig into the plastic layer. The necks are pressed in precisely at a predetermined spacing by means of a gauge. By the application of varying degrees of pressure when the ribs are pressed in on one side and the other side of the neck, one of the U-shaped recesses can be off-center.

In the field of automation technology, processes, which are controlled by stored program controllers (2), are divided into modules, which are also known as function blocks. If possible, these function blocks should be used universally. The interfaces of these modules are different from or independent of the technological parameters of the actual technical function. It is a problem for the user to have access to internal knowledge of the program in order to implement the controller (2) for a specific application. To address this and other problems, a programming tool and programming method for creating programs are disclosed, which will provide the user (1), either additionally or alternatively, with technological insight into a process that is to be controlled and/or regulated. An interface (3) is connected between the user (1) and the stored program controller (2), and a plurality of input masks (5) is offered to the user (1) for inputting technological parameters of the process. Therein a respective input mask (5) is assigned to at least a part of the function blocks.
摘要:
A vessel electrode line (10) for pacemaker stimulation and/or for sensing cardiac actions in the region of the atrium has an oblong base body (11) that receives at least one electrode supply line, and at least one electrode (13, 14) that is mounted on the base body, with the effective diameter of the electrode(s) being nearly identical to the diameter of the base body, and with fixing elements (11a) that essentially do not act as an electrode, and particularly have at least a partial insulating surface, being provided for fixedly positioning the electrode(s) with respect to the vessel wall.
摘要:
The invention relates to a communication system comprising a first subscriber line for a first user terminal to which subscriber line a service feature functioning in a service switching point is assigned, which feature can be activated and/or deactivated from the first subscriber line by the first user terminal. A remote control of the first user terminal via a second user terminal of a second subscriber line is provided to activate and/or deactivate the service feature.
摘要:
A connector for lightwave guides with release levers attached at the narrow sides thereof, which, when lateral pressure is applied, actuate detents. Simultaneously at the narrow sides of the connector casing recesses are provided for the release levers such that the release levers do not rise more than a small amount above the edge of the recess; whereby, the connector can be pulled by manual actuation of the release lever through the recess.
