The memory state register MEM is searched in blocks by the use of "don't care" states generated by circuit D which cause, in circuit ADRL, the generation of all addresses with common values for bit positions of order greater than k-1, k being indicated by a single stage set to "1" to a shift register SPR, and the common values being provided by an exclusive OR circuit EOR receiving the output of shift register SPR, and the output of an address register MAR. A comparator COMP compares the output of shift register SPR with the output of a limit value register G which identifies the highest order bit in which the addresses of the upper and lower working memory locations of the unoccupied group to be identified can be distinguished. The system is controlled by a control mechanism CONTR constituted by ring counters or a read-only microprogram memory. The control mechanism CONTR performs, in dependence on the states of status flip-flops STAT 1, one of the modes SEARCH, ERASE, ERBAS, or WRITE, or passes through a waiting loop. The SEARCH mode causes searching of the memory state register MEM and a base address register BAS for a group of unoccupied working memory locations, the ERASE mode returns to "0" a group of stages in the memory state register MEM, the ERBAS mode searches the base addresses left after the return of such a group of stages, marked by a "1" in the corresponding stage in the base address register BAS, and causes the release of the corresponding working memory group, and the WRITE mode marks the base addresses by writing a "1" in the corresponding stage of the base address register BAS.

Title: Improvements in or relating to shoe-bottom fillers and to the process and machinery employed therefor
IPC: A43D25/14
Filed: 1923-06-04
Abstract: 221,262. Livingston & Doughty, Ltd., (Maxwell, G. H.). June 4, 1923. Fillings, machines for.-A shoe-bottom filler, for example that described in Specifications 17667/06, and 4877/12, [Class 70, Indiarubber &c.], is formed in a plurality of small portions separated by relatively dry comminuted material such as cork, so that the mass holds together, but is provided with planes which enable heat to penetrate the mass quickly. The filler is produced in this form by heating the original mass until it becomes semi-liquid, pouring or otherwise forming a thin layer, coating the layer with cork dust or the like, allowing to cool, separating into fragments, and collecting the fragments into a mass. To prepare this mass for insertion into the shoe, it is subjected to dry and moist heat, preferably from the bottom so that the lower portions become softened first and tend to prevent the mass from caking. Apparatus for applying the filler comprises a heated base plate 1 on which are mounted a reservoir 4 and basin 5. Extending across the reservoir 4 are flues 13 closed at the top, and with openings 30<a> at the forward lower end. A levelling roll 11 and knife block 12 as described in Specification 17653/06 are mounted above the basin 5. Steam pipes with cocks are provided for heating the various parts of the apparatus. In operation, filler is placed in the reservoir 4 and the lid 7 closed. Steam is admitted to the flues 13 by pipes 23, and after heating them and so conveying dry heat to the whole of the filler, escapes by the openings 30<a> into the reservoir 4 where it completes the melting of the filler in the lower part and envelopes each particle with a film of moisture. The operative thereupon raises a door 9 and draws a supply into the heated basin 5. In a modification, electric means are provided for heating the basin 5 and for raising steam.
