Title: Determining the boundary line between touching characters
IPC: G06V30/10
Filed: 1967-07-20
Abstract: 1,125,866. Character recognition. INTERNATIONAL BUSINESS MACHINES CORP. 20 July, 1967 [27 July, 1966], No. 33300/67. Heading G4R. The boundary between two touching characters is determined by comparing the integrated character signals from each of a series of vertical scans thereof. In a first embodiment, the video signal from the photo-multiplier of a flying-spot scanner performing vertical scans of characters to be recognized is integrated for each scan separately, two integrators being used alternatively. The integrated values for each two adjacent scans are compared to see whether there is an increase or decrease between the two scans, a segmentation signal indicating the boundary being produced if two (adjacent) decreases are followed (immediately) by an increase, provided this occurs in the last quarter of the probable character width according to a scan count and provided an " enclosed white " signal (see below) is absent. A second embodiment differs in that two increases rather than one are required. A third embodiment uses four integrators in turn, the outputs of each two integrators used adjacently being compared in a respective comparator (thus four comparators), the segmentation signal being produced under the conditions of the first embodiment. " Enclosed white " signal.-In a circuit for producing this, the video signal is digitized and fed to a two-bit shift register. In a given scan, two adjacent black bits cause a latch to be set whereafter any subsequent white bits in the scan are counted. A count of five prevents further counting (in this scan) and allows any subsequent two adjacent black bits in the scan to set a second latch. This will remain set (until the next character) provided the scan is one of those in the last quarter of the character or the scan just before this quarter. The set state of the second latch enables one input of an AND gate the other input of which is enabled except after the third scan (assuming 20 scans per character) in the last quarter of the character and the output of which is the " enclosed white " signal.

Title: A method of and means for extracting soluble substances from other materials
Inventor: MORTON BENJAMIN CECIL
IPC: C01B17/033
Filed: 1955-11-25
Abstract: 821,048. Making extracts. DEMPSTER & SONS Ltd., R. Feb. 22, 1957 [Nov. 25, 1955], No. 33791/55. Class 81 (1). [Also in Group II] A method of extracting soluble substances from extraction material comprises placing the material in a vessel together with solvent and heating a zone of the solvent about a vertical axis to effect circulation of the solvent upwardly in the heated zone and downwardly through the material. In the form shown the apparatus comprises a vessel 10 containing spent pelleted gas purifying materials 40 and the solvent, perchlorethylene, and a heating tube 16 made of tubes 18 and 20, the annular space 22 being closed at 23. The space 22 is heated by steam, hot water or any other convenient fluid passed into a pipe 24 and returning by a pipe 26 connected at the top and bottom, respectively. Entry of extraction material into the central heated zone is prevented by a perforated or mesh screen 28. Radial passages 42, suitably screened to prevent entry of solid, assist in the circulation, and increase in bore downwardly. The tube 20 is coated with heat-insulating material to direct the heat inwardly. Tubes 30 and 32 are used to heat the vessel 10. Through them fluid such as steam or hot water is passed. Initially extraction material is charged through the opening 15, having a cover 19, to a level just below that of the mesh 28. The tubes 30 and 32 are used to effect any drying, moisture escaping through an outlet at the upper end, aided by an extraction fan or pump. Solvent is then added through inlet 34 to the level shown, the partial vacuum after drying being preferably maintained or increased to aid penetration thereof into the material. The vacuum may be broken or maintained when heating the annular space 22 and circulation of the solvent follows. After a predetermined time the solvent is drawn off through the valve-controlled outlet and fresh solvent is fed. The process is repeated until sufficient soluble substance is extracted, fresh hot solvent is passed downwardly for rinsing, any adhering solvent being removed by a vacuum pump from the material which is heated therefor and then replaced by a new charge. Control of the temperature can enable removal of some extractable substances as vapour at the top during the extraction process. Two or more vessels 10 may be coupled in series, countercurrent circulation of the solvent being employed with a series of vessels. An electrical element may be incorporated for heating the tube 16.
