Title: Data processing device
IPC: G06F13/00
Filed: 1972-12-14
Abstract: 1415322 Data processor OMRON TATEISI ELECTRONICS CO 14 Dec 1972 [21 Dec 1971 (2) 24 Dec 1971 28 Dec 1971] 57753/72 Headings G4A and G4H Data processing system has a dynamic shift register supplying one input of an adder with numeric data, each digit of which consists of a number of bits of binary coded numeric data and a bit indicative of a decimal point. The basic system is shown in Fig. 1 and comprises eight stage shift register X each stage of which has five bit positions m1-m4 and dx, an additional digit stage LR, a gating network G, and a full adder FA whose other input is supplied via gate G9B, e.g. from a second shift register similar to that shown. The data is shifted by bit pulses t1-t5 which subdivide each of a series of eight digit times T1-T8. By enabling OR gate G6 with signals from generator 4 and/or 5 during bit periods t1-t4 and t5 respectively numeric and/or decimal point data is circulated via additional stage LR and AND G2 to induce a one digit left shift. Gates G7 and G8 circulate normally and shift one digit to the right respectively. The full adder is shown in Fig. 4 and includes two half adders 13 and 15 and a carry network which includes a one bit delay 14. In the absence of timing signal T5 gate G15 conducts to add in carries and in the presence of t5 G14 conducts to circulate a carry bit via the delay to ensure that inter-digit carries are not entered into the decimal point bit but are entered in slot t1 of the next digit. Means (not shown) convert hexadecimal addition results to decimal conventionally. Modifications.-Two further embodiments, Figs. 6 and 11 (not shown), are described. In the first the shift register has twelve digit stages four of which are selectively by-passed in accordance with whether 12 or 8 digit data is being proeessed. In the second four shift registers are provided with a gating network which allows shift and circulation as in Fig. 1 and also permits the length of the circulation loop to be varied as in the second embodiment. Display.-A five bit buffer 31 is provided between a shift register stage and a decoder 32 which drives a segmented digit display V1-V8 which may be formed of fluorescent tubes, or photo-emissive diodes. The decoder outputs are connected in common to all digit displays which are individually energized by respective digit timing pulses T1-T8. Inhibit gates A1-A8 are connected between the decoder and the displays and are blocked by the t5 bit timing pulse. Thus the gate outputs have the last <SP>1</SP>/ 5 th of a digit time to subside so that spurious signals do not interfere with the subsequent digit display. The digit pulses T1-T8 may also be shortened in a similar fashion.

Title: Apparatus for recognising graphic symbols
IPC: G06V30/162
Filed: 1970-12-23
Abstract: 1311029 Character recognition ING C OLIVETTI & C SpA 23 Dec 1970 [24 Dec 1969] 61210/70 Heading G4R In a character recognition system characterrepresenting signals from a scanner are passed to a number n of threshold units, each having a different threshold. The resulting n digital signals pass to a circuit which determines which is the best, second best &c. of the thresholds having regard to the line width of the character. The circuit then selects the threshold unit that corresponds to the best threshold for the present character and passes a signal from it to recognition circuitry, this signal representing the next scanned character. If the character is not recognized the character is rescanned and the output of the best threshold unit, determined during the prior scan of this character, is fed to the recognition circuitry. As described the character 17, Fig. 1, is scanned by a cathode-ray tube 11. Photocell 19 passes an analog signal to 5 units 22A-22E which have different thresholds. The digital output signals bA-bE each represent on the threshold value. These signals pass to stores 24, each comprising a number of delay lines and shift registers, Fig. 3 (not shown), so that each stores a matrix of 5 x 5 scan points. As successive bits are fed to the stores the matrix is effectively scanned over the character. The parallel-bit output from the stores passes to unit 27 which passes the output from one store only, under control of the threshold determining units 43, 44, 46, 47, 74 to unit 28. This unit assigns to a cell in the 5 Î 5 matrix a value dependent on the values of adjacent cells, as described with reference to Fig. 6 (not shown), and so eliminates short breaks in the character. The resulting signal passes to a store 94 comprising delays and shift registers, Fig. 4 (not shown), which supplies a moving 3 x 5 matrix of scan points to unit 95 which, by examination of various cells of the matrix eliminates small vertical and horizontal gaps, Fig. 7 (not shown). The output of this unit passes to recognition circuitry 31. The signals from the stores 24 also pass to units 43A-43E which perform logical operations on them to derive values P2, P5 which are functions of the values of sub-matrices of cells in the 5 x 5 matrix. The signals P2, P5 are applied to reversible counters 44A-44E to provide signals representing #P2-#P5. The counter outputs feed units 46, 47, 74 which indicate which of the thresholds set in 22A-22E is the best, second best &c. for the character scanned. These indications are passed to unit 27 referred to above, to pass the output of one of the stores to recognition circuitry. When a character has been recognized the threshold is assumed to be optimum for the next character but if this character cannot be recognized the character is rescanned, the store output selected now corresponding to the best threshold determined during the previous scan of this character. If the character is still not recognized the store output selected corresponds to the second best threshold, and so on.

Abstract: 743,716. Filters. LUCAS (INDUSTRIES), Ltd., J. Feb. 3, 1954 [Feb. 5, 1953], No. 3239/53. Class 46. An ice trap for use in the fuel supply system of an aircraft comprises the combination of a casing having an inlet and an outlet, and a spirally coiled length of foraminous or other permeable material arranged within the casing so that normally fuel can flow from inlet to outlet through the convolutions of the material, thus enabling ice carried by the fuel to be intercepted, but in the event of obstruction of this flow by ice accumulated on the material, fuel can flow from the inlet through a spiral passage between the convolutions to the outlet. In Fig. 2 liquid fuel entering at b normally passes through successive turns of a spiral of wire gauze or perforated sheet metal d to an outlet e in the end of a casing a. In the event of the interstices of the coil material becoming clogged by ice the fuel flows along a spiral passageway formed by the spacing between the turns of the coil, the path taken being indicated by arrows. The far end of the coil is closed by the end of the casing containing the outlet c, while the near end is closed either by the adjacent end of the casing or by a disc (not shown). According to the Provisional Specification further embodiments are described. In one, the inlet and outlet are provided at opposite ends of a cylindrical casing across the interior of which there extend, transversely, foraminous partitions. These partitions are provided near opposite ends alternately with openings which together with the spaces between the partitions form a zig-zag path from inlet to outlet, this constituting the alternative path. In another embodiment the openings are not provided but the foraminous partitions are pivoted, e.g. resiliently, at opposite edges alternately, the other edges being free and normally abutting against ledges on the adjacent sides of the casing. In a further embodiment the casing is of rectangular cross-section with inlet and outlet at opposite ends, two zig-zag sheets of foraminous material being arranged in spaced and overlapping relationship between the ends. A zig-zag path communicating at opposite ends with the inlet and outlet is thus provided between the two sheets.
