Abstract: During the formation and demultiplexing of data channels containing data packets which originate from a multiplicity of transmitting stations and are intended for a multiplicity of receiving stations, a bottleneck can occur where the individual data packets are assembled or distributed again. The bottleneck is eliminated by the data packets being uniformly distributed to all distribution facilities (CCT) before they are finally distributed, and by additional means (ATERI, DSN2) which provide the possibility for such a uniform distribution. The invention is described using the example of common signalling channels.

Abstract: An improved electronic postage meter which includes a microcomputer (17), redundant memories ("BAMs") (35a-b), and fault flip-flops (30a-b). Im­proved circuitry for controlling the writing to the BAMs includes a timer ("BAM-protection timer") (40) coupled to the write-enable input of each of the BAMs. The BAM-protection timer has a trigger input (43) cou­pled to the microcomputer. The microcomputer is pro­grammed to execute an instruction to generate a trigger­ing signal at the BAM-protection timer's trigger input immediately prior to executing an instruction to write to the BAM. This opens a window for writing; the dura­tion of the window is set to be just long enough to allow the completion of the write operation. The fault flip-flops, once set, unconditionally prevent writing to the BAMs, regardless of any other signals that might be present. The setting of the fault flip-flops is controlled by a first timer ("watchdog timer") (60) and a second timer ("second-chance timer") (62). In normal operation, the microcomputer periodically generates a trigger signal for the watchdog and second-chance timers. The watchdog interval exceeds the maximum interval be­tween triggers under normal conditions. If a trigger is not received, the watchdog timer resets the microcom­puter. The second-chance interval is longer than the watchdog interval, so that the second-chance timer times out and sets the fault flip-flops only if the restart still fails to produce a trigger signal within the spec­ified time.

Abstract: A system for monitoring ink flow from an ink storage tank (10) to at least one ink fountain (20) of a high-speed, web-fed printing press employing a scale for measuring the weight of the ink storage tank and comparing weight signals from the scale at successive times to determine the weight of ink consumed over the interval between readings. A pump (12) is associated with the storage tank for pumping the ink to the fountain via coupling lines. An ink level sensor detects the level of ink in the fountain and provides an ink demand signal for operating a valve means in the ink coupling line to in turn cause ink flow to the fountain so as to provide replenishment of ink thereat. With the use of plural fountains (20), means are provided for prioritizing delivery to the fountains so that individual ink consumption on a per fountain basis can be determined. In this regard, the system also employs a volume sensor (13) preferably in the form of a pump stroke position sensor for determining incremental weight delivery per stroke.

Abstract: In this system the light reflected back over the path (10a) to be measured is fed directly into a semiconductor laser (8a). As is commonly known, the introduction of reflected power through the front, or emitting, facet of the laser actually alters the power present in the laser with an attendant effect on the signal from a photosensor (15) usually located on the rear facet of the laser. The output signal from the photosensor associated with the laser has an asymmetric sawtooth (triangular) waveform. This is in contrast to the output signal from a conventional interferometer which has a sinusoidal waveform. 
     The photosensor output signal is profoundly affected by the return beam. Also unexpectedly, the sawtooth output signal from the photosensor is an essentially linear signal over the range between adjacent fringes. That is, except for the transition at positive and negative peaks. As the path length (10a) of the reflected beam is increased or decreased, the sawtooth output signal changes in a direct linear relationship to the change in path length. This allows precise measurement of changes in distance less than the distance between adjacent fringes.
