Filed: 1970-10-08
Abstract: 1293831 Character recognition INTERNATIONAL BUSINESS MACHINES CORP 8 Oct 1970 [15 Oct 1969] 47862/70 Heading G4R A character recognition system controls the recognition process by means of control and measurement words from a data store some of which include fields which are compared with feature-representing signals from the unknown character to derive truth values which are operated on logically under control of further fields to control production of a character identity output or repetition of operation using another control word. As the unknown character is scanned and shifted in digitized form into a shift register, features are recognized by logic to set respective ones of 240 measurement latches. A control word is read from a read-only memory into a control word register followed by a series of measurement words read out into a processor register in turn from consecutive addresses. For each measurement word in turn, three 12-bit portions are selected in turn, 8 of the 12 bits selecting one of the 240 measurement latches or one of 16 R-bit latches (see below), the state of the selected latch being compared with a further one of the 12 bits, the equal/unequal result of the comparison being subjected to a logical operation specified by the remaining 3 of the 12 bits. These 3 bits may specify inner sum, outer product, end of recognition function (i.e for this control word), or one of several thresholds to be exceeded by a count of comparisons (see above) giving equality. After, in general, a series of measurement words, a termination indication is given as an up signal on one or two lines in response to the logical operation. If a particular op code bit in the control word register is 1 and an up termination signal is present on a particular one of the two lines, a field of this register is gated to an output as the character identity and operation stops, but in general the termination indication simply selects one of two fields of the control word register to address the memory to obtain the next control word and the previous operations repeat. Also, if another op code bit in the control word register is 1, a 4-bit field of this register is used to select one of the 16 R-bit latches which is then set or reset according to the state of the termination indication. The control word could also include op code bits for determining recognition conflicts and errors, or for causing rescan.

The inner tube 13 of the liquid heat-exchanger is fed by pump 11, has apertures 14 at its upper end for supplying vapour to tube 15 and extends through the absorber vessel en route to the absorber. Liquid and vapour from tube 15 are supplied through an upwardly inclined tube 19, which acts as a rectifier, to pipe 20 from which liquid passes to pump 11 and vapour to the condenser 21 via a separator 22. Defrosting.-The upper part of tube 15 is bent to form an inverted U, the left-hand leg 28 of which communicates through pipe 27 with the evaporator and, through a siphon tube 30, with the right-hand leg of tube 15.
