Abstract: CONTROL INFORMATION COMMUNICATION ARRANGEMENT      FOR A TIME DIVISION SWITCHING SYSTEM            Abstract of the Disclosure A time division switching system having distributed control processors is disclosed.  The distributed processors exchange control messages and cooperate in the completion of talking paths between subscribers.  Each control message includes an address portion defining the destination for the control message and is transmitted to a time-shared space division switch on the same time multiplex lines that speech representations are transmitted.  Control messages are routed by the time-shared space division switch to a control distribution unit where the address portion is interpreted.  When the address portion defines a distributed processor which controls the time-shared space division switch, the control distribution unit transmits the associated control message directly to that processor.  Alternatively, when the address portion defines one of the other distributed processors the control distribution unit transmits the associated control message to the defined processor via the time-shared space division switch.

Abstract: ABSTRACT OF THE DISCLOSURE      A device for axial shirring of synthetic tubular material by forming a continuous helical fold.  As the unshirred tubular material moves along a mandrel, it is engaged by the teeth of four shirring rolls having their axes located in a plane transverse to the mandrel axis.  This assembly of shirring rolls revolves about the mandrel axis, and the shir-ring rolls are interconnected for timed rotation with each other and preferably they are all driven from the assembly revolving drive means.  Each of the shirring rolls is mounted on a shaft which is non-rotatably fixed to the revolving holding member, and each shirring roll is in turn rotatably mounted via bearing means on its respective shaft.  Pairs of tapered gears are fixed to the sides of the shirring rolls for rotation therewith about their respective fixed shafts.  A first one of these tapered gears is driven by a drive means while the tapered gears between the remaining shirring rolls mesh to carry the driving force to the other shirring rolls.

Abstract: ABSTRACT OF THE DISCLOSURE         A control method for screwing down rolls in a reeling mill wherein the desired amount of reduction in the wall thickness of a seamless pipe being rolled is determined for the longitudinal direction of the pipe from the outside diameter and average wall thickness of the pipe being supplied to the relling mill and the desired outside diameter of the pipe leaving the reeling mill, the actual amount of reduction in the wall thickness of the pipe being rolled is calculated for the longitudinal direction of the pipe from the temperature of the pipe being supplied to the reeling mill and the rolling torque of a rolling motor, and the degree of screwing down of the reeling rolls is controlled so that the actual amount of reduction in wall thickness is equal to said desired amount of reduction in wall thickness, as well as an apparatus for effecting this method.   According to this method and apparatus, the torque of the rolling motor is measured continuously to detect the actual amount of reduction in the wall thickness of the pipe at particular times, and so, only one value is determined for the amount of correction of the gap between the two reeling rolls when the actual amount of reduction in wall thickness deviates from the desired amount of reduction in wall thickness.  This achieves very reliable control operation without hunting or delay effect.  The control method of this invention takes into consideration the change in the temperature in the longitudinal direction of the pipe being supplied to the reeling rolls, so the pipe leaving the reeling mill has a uniform outside diameter in the longitudinal direction, and as a particular advantage, the outside diameter at both ends of the pipe can be controlled to become equal to the desired value.

Abstract: APPARATUS AND METHOD FOR CONTROLLING THE POSITION                  OF A ROTARY HEAD     ABSTRACT OF THE DISCLOSURE         The position of a rotary head which is mounted on a deflection device is controlled as the head scans successive tracks on a record medium.  Tracking drive signals are generated as a function of the deviation of the head relative to a track scanned thereby, such tracking drive signals representing the configuration of that track relative to a trace scanned by the head. The tracking drive signal is sampled at successive locations along the trace to produce successive samples as the head scans the track.  Previously stored samples are compared to the successively produced samples, and any difference between compared samples is used to correct the stored sample by a predetermined amount irrespective of the actual difference between the produced and stored samples.  Thus, the stored samples are successively corrected; and the corrected samples are returned to the storage device from whence they came.  Hence, the stored samples gradually are corrected to represent the configuration of the tracks scanned by the rotary head.  When the head reproduces signals from the record medium, the generated tracking drive signals are used to control the deflection device so as to make the head coincident with the track being scanned thereby.  When the head is used to record signals, the stored samples are used to control the deflection device before such samples are corrected.  In one embodiment wherein the head is used for recording, the stored samples are compared to reference samples, whereby the stored samples gradually are corrected to conform to the reference samples, and the stored samples also are used to control the deflec-tion device so that the traces scanned by the head gradually conform to the configuration represented by the reference samples.                           -ii-

Abstract: ABSTRACT        A multitasking data processing machine supports virtual memory comprising a plurality of segments, and has physical memory comprising relatively fast main memory and relatively slow secondary memory.  A constantly varying subset of secondary memory paged contents is copied in main memory page frames.  When a memory access is required during operation of the machine, a virtual address is generated, which must be translated into a physical address, in order to address main memory.  The data processing machine provides an indexed local random access memory (T/RAM) for storing previously translated addresses.  The T/RAM has a capacity of one entry for each page of supported virtual memory.  Before a translation is performed, The T/RAM is indexed by the virtual address; in case of a T/RAM fault, translation is performed and the translated physical address is loaded to the indexed location before restarting the memory operation.  A subsequent reference to the same virtual address indexes the previously translated physical address, which is then used for addressing main memory and is also applied to index a reference/change table.  A stored monitor/no monitor signal associated with each segment of virtual memory controls the storage of referenced virtual addresses for monitored segments.  Upon a task switch, the stored virtual addresses are applied to index the corresponding T/RAM entries for rapid selective and partial clearing of the T/RAM.

Abstract: ABSTRACT: "Digital-to-analog converter for bipolar signals"     In a digital-to-analog converter for bipolar signals all the bits change when the signals pass through the zero level. This result is a poor signal-to-noise ratio owing the small signal and the larger noise contribution of the switching transients. The invention is to add a digital number to or subtract it from the digital input signal as an offset. As a result of this, the point at which all the bits change is shifted towards a higher amplitude, which improves the signal-to-noise ratio and the distortion behaviour in the case of digital audio signals.
