    Abstract: A symmetric switching device which can be personalized to do any mathematical operation relying upon the mounting of the number of bubble domains present. This can be used as a universal logic element to provide any logical function. The device will handle multiple inputs and is rewritable to provide the desired function. The device broadly comprises a counter for counting the number of 1 bits in the input data stream, a means for producing a control data stream for personalizing the switch, and a comparison means for comparing the counter output and the control stream. A particularly suitable embodiment comprises a bubble domain sifter for shifting the position of the bubbles in the input data stream, a leading bubble detector for detecting the leading (first) bubble in the input data stream, means for creating a personalized control bubble stream for designating the function to be performed, and means for comparing the personalized control bubble stream with the output of the leading bubble detector to provide a circuit output representing the output value of the function desired. Means are provided for serial or parallel data inputs to the symmetric switching circuit. Any known type of domain propagation structure can be used to implement this device.

    Abstract: AN APPARATUS FOR TRANSPOSITION SORTING OF EQUAL LENGTH RECORDS IN OVERLAP RELATION WITH RECORD LOADING AND EXTRACTION An apparatus for sorting of equal length records with the sorting time maximally overlapped by the time taken for loading and unloading of records. The minimal structure consists of a decision mechanism linked to and associated with a network of ladder structures. The activity within the network is so synchronized that the sorting activity in most ladders occurs while some ladder within the network is still undergoing the loading of input data; and during the unloading phase, the individually sorted data from each ladder are merged concurrently to produce a sequence of sorted records. The overlap between sorting and loading varies from 0 for records requiring no loading/unloading, to 100% for multi-ladder networks with loading/unloading.

    Abstract: 1487121 Shift registers INTERNATIONAL BUSINESS MACHINES CORP 1 May 1975 [14 May 1974] 18157/75 Heading G4C To edit a text, a shift register storing a line of data bits representing text has a normal path 34 (Fig. 2A) and a by-pass path 36 so that the order of the bits may be changed, gaps in the data may be closed and data bits may be deleted. The shift register may be either a medium capable of supporting magnetic bubble domains in which case drive pulses for the register in the form of an unchanged repetitive sequence of drive pulses are provided by a rotating magnetic field or a charge coupled device in which case three phase propagation lines receive successive signals. As described the normal path includes a freeze and input/output position at which new data may be written by a write circuit (48, Fig. 2B, not shown), annihilated (in the case of the bubble domain embodiment by passing a large current through freeze loop (46)) or held whilst other data is shifted round the by-pass loop. The editing shift register (24, Fig. 1, not shown) is connected between the read decoder output from and the write decoder input to a plurality of shift registers (SR1-SRn) used for storing data text. A spare shift register (SR) is provided so that the contents of the shift registers may be interchanged.

    Abstract: An apparatus for performing efficient transposition exchange sorts among equal length records is described. The apparatus takes advantage of the flow steering property of linkable circulating storage loops to minimize the average access time by positioning information closer to the output port in a storage structure. The apparatus is formed from a linear array of equal size shift register loops each holding one record. The loops are switchably interconnected such that when two boundary switches are set in a first mode, the contents of each loop normally circulate wholly therewithin. Upon a common boundary switch being set in a second mode, the contents within a first loop flow into a second loop and vis-a-vis. By setting a common boundary switch to the second mode, the contents of a pair of adjacent loops are exchanged in the duration of one loop cycle time. Further exchanges can be started before a previous one is complete; this overlapping of operations can lead to an effective exchange rate of two exchanges per loop cycle. By repeating the exchange for consecutive pairs of loops, then the contents of any reference loop can be migrated to an output port D loops away in (D + 1)/2 loop cycle times.
