Title: Data processor
IPC: H03M5/00
Filed: 1971-09-20
Abstract: 1315060 Data processing INTERNATIONAL BUSINESS MACHINES CORP 20 Sept 1971 [30 Oct 1970] 43658/71 Heading G4C The invention relates to a data processor for encoding fixed length data-words into a variable length compact code (e.g. a Huffman code) for efficient storage. The processor comprises a first permanent store (Fig. 1) which contains all P data words (A-L) of a data base in a fixed length code (e.g. the 12 data words of the illustration could be coded in a 4-bit code). Each of the P data words (column 1) is associated with M address words (columns II-VI) each assigned to one of M code groups 0-4; a group number (column VII) designating one of the code groups; and a coding set number (column VIII) designating one of N coding sets (0,1). A second permanent store (Fig. 2) contains N sets of P data words in a variable length code (column IX). Each of these words has associated with it a word indicating its length column X); one of the coding set words (column XI) and one of the address words (column XII). All of the alphanumeric symbols in Figs. 1, 2 represent binary data words. First and second registers (14, 64, Fig. 3, not shown) are associated with the respective permanent stores; these have the same number of bit storage positions as each row of the respective stores. In use a word to be encoded is entered into the portion (68) of the first register corresponding to column 1. A comparator compares this word with each row of column 1 in turn and when a match is found an address from a predesignated one of the columns II-IV and the group and coding set numbers are read from the matching row into the first register. The group number serves to predesignate the column from which the address will be read for the next data word to be encoded; the address and coding set numbers are transferred to the second register. A further comparator then compares them with each of the rows in columns XI and XII in turn and when a match is found the values from columns IX and X of the matching row are read into the register. The length value is subsequently used to determine how many digits are transferred out of the second register (the encoded word) thus excluding "dont care" bits in the blank positions of column IX. The above embodiment is described in some detail (Figs. 4A-4H, not shown) with gating and clocking details for the various stages of the encoding. A further embodiment (Fig. 5, not shown) is briefly described in which the first store is dividedinto two parts; the addresses are read from one of these, the group and coding sets from the other. Both embodiments can be used in reverse to decode a variable length word the embodiment of Fig. 5 being faster in this mode.

Abstract: 1305485 Delivering sheets; collating apparatus TEXTILMASCHINEN FABRIK SCHWENNINGEN GmbH 11 Sept 1970 [12 Sept 1969] 43684/70 Heading B8R [Also in Division B6] Piled sheets are bound together along one edge by punching one or more holes in the pile adjacent to the edge and introducing adhesive into the holes. The punches may be tubular and the adhesive fed through the punches. As shown, however, the tips of the punches 54, Fig. 1, enter an adhesive container 58 near the completion of a punching stroke, and adhesive is carried through the punched holes during the withdrawal of the punches. The container 58 may be continuously replenished by feeding a strip of glue and heating the container to liquefy the glue. To ensure that the melting of the glue takes place only in the container the inlet channel may be cooled by an air current which also assists the rapid setting of the glue. The punches 54 are mounted on a beam 36 carried by pivoted arms 38, 40 driven to cause operation of the punches. A plate 52 for clamping the edge of the pile of sheets is carried by the beam 36 so that it is movable against the action of springs 48, 50 towards the beam. The plate 52 and a supporting table 12 for the sheet pile have perforations for receiving the punches 54, the container 58 for adhesive being mounted below the table 12. After the withdrawal of the punches 54, the bound sheets are engaged at the edge opposite to the bound edge by a gripper device 51, 53, Fig. 4, which moves the pile away from the punches. Subsequently rollers 22, carried by arms 24 fixed to shafts 26 linked together, are moved downwardly so that in co-operation with driven rollers 18 extending into slots 20 in the table 12, they move the pile into a container 62 inclined so that the pile edges abut against walls 64, 66 of the container. The sheets forming the pile are forwarded separately from stacks by devices 104, Fig. 1, and brought together at discharge apparatus 102 which feeds the pile on to a table 70 inclined downwardly towards the table 12 and also inclined downwardly towards a side guide 92, Fig. 2, to align the side edges of the pile. A cross-bar 94 aligns the front edge of the pile, and is subsequently lowered beneath the table 70 to allow the pile to be moved forward, this being effected by the lowering of rollers 80 ... 84 co-operating with driven rollers 72 ... 76 projecting through slots in the table. The pile is forwarded to another cross-bar 96 and forwarding rollers, whilst another pile is assembled at the bar 94. When the bar 96 is retracted, the pile passes on to the table 12. The table is suspended in the main framing and is vibrated by a vibrator as each pile reaches an aligning bar 94, 96 to ensure proper alignment of the sheet edges.

Abstract: 1521888 Time-sharing data processor POST OFFICE 13 Oct 1975 [18 Oct 1974] 45220/74 Heading G4A A processor operating on data carried by a plurality of TDM channels includes a register 4, Fig. 1, having as many stages as there are channels for storing program functions to be performed for the respective channels, the register 4 circulating in synchronism with the channel switching rate so that the program functions (e.g. current instruction, partial result, next instruction address are available at a particular register stage R n  synchronously with the corresponding data on the TDM channels 3, and an additional, non-synchronized processor is coupled to the register 4 by an access unit 8. The form of access unit depends upon the relative speeds of the two processors. When the register 4 cycles at a high rate relative to the data rate of the non-TDM processor, the channel number of data to be transferred is held in a channel number store (21). Fig. 2 (not shown) and compared with successive channel numbers supplied by sync. block 6 and identifying the channel currently allocated to a single access stage (R n ) of the register 4. When equality is detected the comparator enables input and output gates for the access stage. When the data rate of the non-TDM processor is greater than the shift rate of register 4, access unit 8 may comprise a separate input and output store for each channel the stores being coupled to the access stage of register 4 in succession by sync. block 6 when a transfer has been requested by the non-TDM processor. In the access unit 8 shown in Fig. 5 the channel number for a data transfer request is entered in a store 21 and is added to a count (53) which is incremented in synchronism with the shifting of the channels through register 4 whereby a decoder 52 tracks a requested channel as it passes through register 4 and enables corresponding pairs of read and write gates WR, RR. A busy F/F 23 is set by a transfer request and provides a busy signal to the non-TDM processor until the transfer has been completed. A time-independent access unit is described, Fig. 6 (not shown) in which a channel number comparator is provided for each stage of register 4 to enable access to program information irrespective of which stage of register 4 it is currently located in.
