Abstract: Method for allocating the switching-oriented resources of a communication system for switched connections and permanent circuit connections. Call duration information (vdi) is formed in the communication terminal equipment connected to a communication system for switched connections (W) whose call durations can be determined. This call duration information (vdi) is communicated to the communication system within the framework of the call setup. In the communication system, the ending times of the switched calls are calculated after the through-connection of the switched connections (W) and those switched connections (W) are selected whose indicated call durations end lying closest to the switching deadline before the following switching deadline of a deadline permanent circuit connection (FW). Dependent on the scopes of the switching-oriented resources (WR) allocated to the selected switched [or: dialed] connections (W) and on the scopes of the switching-oriented resources (VR) required for the deadline permanent circuit connections (FV), switched connections (W) are selected from these. Their switching-oriented resources (VR) that become free are then reserved for the respectively provided, deadline permanent circuit connection (FV).

Title: Bar code and device for reading the bar code
Inventor: KIEFER DIETER
IPC: G06K7/08
Filed: 1993-02-27
Abstract: The bar code (2-4) is cut (notched) into an electrically conductive material (1). As reading head, the device has an electromagnet (6) arranged in a tuned circuit (5, 6) in such a manner that in the event of the reading head being placed upon the material (1), the electromagnet (6) induces a locally closely delimited eddy current (9; 10) in the material (1). In addition, it has a device for detecting the different magnetic resistance of the tuned circuit (5, 6) in the event of placing the reading head over the uncut material and over a notch (4), as well as for converting the detected differences into the information contained by the bar code. The application of this bar code and the device can be used, for example, to check the workpieces used in a production process for correctness. Contamination of the bar code by means of lubricants or coolants and by particles of dirt does not disturb the reading. A complete coverage is also possible, for example with a primer or, in the finished product, with a lacquer. The bar code can even be made invisible by being filled in, whether it be because of the appearance of the object or in order to hide the bar code. <IMAGE>

IPC: B62D5/32
Filed: 1993-05-04
Abstract: A steering unit (50), incorporated in a control circuit (13), has two branch pipes (36,37), and builds up a higher pressure in one than in the other. A setting circuit (12) contains a control valve (30), which is moved in opposite directions by the pressure-difference between two control chambers (31,32) connected to the respective branch pipes, so as to supply pressure to different chambers (19,21) in steering rams (10,11). The two circuits are separate, and the pressure which can be built up in the control circuit is less than that possible in the setting one. The control circuit can be connected to a pressure source, particularly a hydraulic pump (40), this working at a lower pressure than that (22) supplying the control valve. It can be of the constant-output type, supplying a pilot-controller with directly-controlled reducing valves. This serves a further control valve for another consumer unit.

Title: Feeder for gatherer-stitchers
Inventor: KRATZSCH ACHIM
IPC: B65H39/04
Filed: 1993-07-31
Abstract: On sheet separating devices of sheet feeders for gatherer-stitchers, separation disturbances occur in the separation of folded sheets, in particular of smooth folded sheets having a high basis weight, from a standing pile, such that retaining needles are used to avoid the occurrence of doubling. As a result, in turn, the folded sheets fixed in this manner are damaged when pulled out of the pile and often separated obliquely in an uncontrolled manner. By means of the arrangement according to the invention and design of a suction shoe, these disadvantages are avoided, in that the following sheet is held in its position at its rear edge during the separation operation. The suction device according to the invention is preferably used on feeders for gatherer-stitchers, in particular in functional connection with the assigned sheet separating device. <IMAGE>
