Title: Character reader
IPC: G06V30/10
Filed: 1965-06-29
Abstract: 1,087,498. Automatic character reading. RADIO CORPORATION OF AMERICA. June 29, 1965 [Aug. 13, 1964], No. 27607/65. Heading G4R. In a character reader, the character is scanned by a succession of vertical scans and feature elements of the character are extracted from the video signals, the scans being counted to divide the character into right- and left-hand zones 1, 3 and 2, 4, Fig. 2, and the distance from the top of the character being measured to divide it into top and bottom zones, the feature element signals being appropriately combined with the four zone representations to provide signals from which the character is identified. The characters move past the scanner, which may be a vidicon tube or a slotted disc scanner and the video signals produced are quantized, Fig. 3, and applied to a delay circuit 60, Fig. 4a. Two delays 62 and 64 each equivalent to one scan make available the previous scan, " B," and the scan before that, "C." The present scan is designated " A." The character area is covered by seven scans so that scan 4 indicates the centre of the horizontal dimension. The scans are counted in a counter which gives an output at count 4 to set a flip-flop circuit. The " 0 " output indicates that the scan is still on the lefthand side of the character. When the flip-flop is set the " 1 " output indicates that the righthand side of the character is being scanned. A horizontal centre line (which may not be straight) divides the character into top and bottom. This is measured from the top boundary of the character by taking a set period from the appearance of A together with B or C or both B and C together. Either of these conditions set a flip-flop 90 to start a ramp generator 92 which, after the set period, exceeds a threshold level to cause comparator 99 to indicate that the bottom half of the character has been reached. Inverter 96 indicates that the scan is still in the top half of the character. In addition there is a valid stroke detector 100 designed to ignore gaps in character strokes or spurious signals due to specks and smudges. Circuits are provided for detecting forks and joins between the strokes of a character and other circuits check these indications for reliability. The fork and join indications are combined with the zone indications and applied to stores. The outputs of the stores are applied to a recognition circuit to identify the character scanned.

Title: Electrical control equipment
IPC: B61L19/06
Filed: 1958-08-29
Abstract: 893,099. Points setting; fouling protection. STANDARD TELEPHONES & CABLES Ltd. Aug. 29, 1958 [Sept. 4, 1957], No. 27794/58. Class 105. In a system for supervising the provision of fouling protection for a points W1 from points W2, W3, W4 and signal S1, fouling protection setting relays FLS2 and SV1, associated with points W2 and signal S1, respectively, are prevented from operating and passing on or carrying out the required setting if a supervisory signal or an interfering potential is present on a supervisory line. Fouling protection for points W1 is obtained from points W3 and W4 locked in their normal positions and signal S1 locked at danger. Changeover of contacts FlS11 of fouling protection setting relay FlS1 (not shown) associated with points W1 reverses the potential on a search lead connected to winding 1, 2 of fouling protection setting relay FLS2 associated with points W2. If supervisory relay FLU2 is in its normal (deenergized) condition and the excitation of holding winding 5, 6 of relay FLS2, energized via resistor Wi22, is not increased by the presence of a supervisory signal or interfering potential on a supervisory line which can be connected to relay FlU1, relay FLS2 is counterenergized and its contacts changed over. At contact FLS21, the potential on a search lead connected to a relay set associated with points W3 reverses and if points W3 are in their normal position, points locking relay WV3 releases and in circuits (not shown) locks the points, in addition, contact WV31 completes the circuit to supervisory relay FLU2 which energizes. At contact FLS22 the potential on a search lead connected to winding 1, 2 of signal locking relay SV1, associated with signal S1, is reversed whereby relay SV1 releases, if there is no supervisory signal or interfering potential applied to its other winding 5, 6 from a supervisory line connected between the relay sets associated with signal S1 and points W4. Relay contact SV12 reverses and connects this line to that associated with points W2 and contact SV11 reverses the polarity of the potential on a search lead connected to the relay set associated with points W4. If the points are normal relay WV4 releases and locks the points. At contact WV41 positive potential is applied to the supervisory line which operates fouling protection supervisory relay FlU1 at points position W1.

Abstract: 1317062 Gas purifying SOC D'INSTRUMENTATION SCHLUMBERGER 11 June 1970 [17 June 1969] 28305/70 Heading BIT Apparatus for eliminating water and solid' particles from a gas to be analyzed comprises flexible inlet tube 2 leading to a fan cooled condenser 3 to condense out the water vapour present which is removed in separator 6 in the form of a funnel 10 filled with glass balls 7, the lower end of the funnel acting as a siphon of outlet 11. The water-free gas passes into tube 12 which splits into two branches 13 and 14, branch 13 having an adjustable restriction 18. Gas passing along tube 14 is filtered in filter 15, suitably of the round flat paper filter type, and then passes into analyzer 23. The gas which is drawn round the system by pump 30 then passes into the centre mixer 26, which is in the form of a horizontal cylinder, where it is mixed with the by-pass gas from line 13. The mixer also receives outlet 11 from the syphon at its lowest point and the inlet 27 of the pump at a height "L" from the bottom of the mixer. The system when combined with a pump of large throughput results in a system in which the pressure difference between the syphen and the mixer is small, e.g. 10-15 cm. of water, the mixer being at the lower pressure, this pressure difference being adjustable by means of adjustment of restriction 18. This arrangement means that the device is independent of pump surges, e.g. on start up, such surges being absorbed by the height "h" of water which constitutes a reserve head. Also, the device may be inclined at an angle, e.g. in transport, without danger of water getting into the analysis chamber. A bypass is provided around the analysis chamber containing a floattype flow meter 33 and photoelectric detection means 34, 35 to stop the pump in the event of the gas flow from filter 15 ceasing for any reason.
