Patent GB-1415916-A (GB)
Title: Character recognition system and method
IPC: G06V30/146
Filed: 1973-01-18
Abstract: 1415916 Character recognition systems H BAR-LEV 18 Jan 1973 [21 Jan 1972] 2642/73 Heading G4R The system employs a column of photodetectors to scan a row of characters. A sampling pulse is generated each time a particular one of the detectors senses a black-white or white-black transition. Each sampling pulse causes the photo-detector outputs to be sampled, the samples passing to recognition circuits. The characters are optically normallized and centred. The characters to be recognized are projected on to the moving column of detectors by a variable magnification lens system. The speed of movement of the detectors is fast when margins are detected and relatively slow during scan of the characters. At the end of each line the detectors are moved by one line spacing, and at the end of the last line are moved back to the top of the document. Fig. la, shows a character e and the column of detectors D1- D22. The particular one of the detectors, mentioned above, is D10. As the column scans across the character D10 detects a transition when it reaches positions shown at 1 and 2. At these instants, and also at position 3 when all the detectors sense white, a sampling pulse causes the present states of the detectors to be read in to a shift register store. The recognition circuitry comprises a number of AND gates, one for each character to be recognized. Each gate is connected to certain of the cells of the store, either direct or via inverters, so as to detect the presence of certain combinations of black and white cells. For example, to identify the letter shown the cells corresponding to the detectors positions indicated by the heavy rectangles are ANDed together. To ensure that the gates are enabled only when a required number of sampling pulses has been generated, in the present example 3 pulses, the sampling pulses are counted and the counter outputs connected to the relevant gates. When a character has been identified, e.g. for controlling a braille machine, the gates are inhibited and the various preceding units reset prior to scanning the next character. Centring and magnification control.-In one arrangement two detectors which, if the character line is correctly centred, lie one immediately above and one immediately below the edge of the characters, (excluding the ascenders, if any) are connected to threshold units via averaging units and respectively control the upward and downward movement of the detector column. Two other detectors which, if the character line is centred, straddle the bottom edge of the characters (excluding the descenders, if any) are also passed to threshold units via averaging circuits to control the magnification by adjustment of the lens system. In another arrangement, Fig. 4 (not shown), only one detector at the top and bottom of the character is employed for these purposes. The average of the difference in their outputs is determined to control the vertical centring, and the average of their sum is determined to control the magnification.

Patent GB-294906-A (GB)
Title: Improvements in and relating to compositions for and methods of preserving and protecting vegetable substances
IPC: B27K3/32
Filed: 1927-01-31
Abstract: 294,906. Curtin, L. P. Jan. 31, 1927. Vermin-destroying compositions. - A process for the preservation of vegetable substances such as wood, consists of impregnation with a solution containing water soluble components, including a metallic salt or salts, together with an agent or agents capable of preventing premature precipitation of insoluble compounds and of rendering the solution stable, or sufficiently stable to permit of its use for impregnating or spraying purposes, the components being capable of reacting, on exposure to the atmosphere, by oxidation or evaporation or both, to produce a compound of low solubility and high toxicity. In the example described, cupric arsenite is produced, in or on the substance treated, from a solution containing a cuprous compound and arsenious acid, by oxidation on exposure to the atmosphere. The solution consists of 1000 lbs of copper sulphate, 240 lbs. of sodium bisulphite, 305 lbs. of sodium carbonate, 1500 lbs of sodium chloride, 200 lbs of white arsenic, and 170 lbs. of sodium fluoride, dissolved in 4000 gallons of hot water. The reactions are probably as follows : the sodium bisulphite reduces the copper salt to the cuprous state, the cuprous salt being held in solution by the sodium chloride. The sodium hydrogen sulphate resulting is neutralized by the sodium carbonate. When oxidation of the cuprous salt takes place in the presence of atmospheric 'air, it is transformed partly into cupric arsenite and partly into cupric chloride. Part of the latter is precipitated as fluoride by the sodium fluoride. Reducing agents such as sulphurous acid, salts of hydrocyanic acid, salts of thiosulphuric acid, or arsenites may be used in place of sodium bisulphite, and instead of copper sulphate, cupric acetate or cuprous chloride in sodium chloride solution may be used. In the latter case, the use of a reducing agent, apart from that necessary to prevent premature precipitation, is not necessary. Alkali hydroxides, borax, sodium bicarbonate, or lime, may be used in place of sodium carbonate: calcium chloride may replace the sodium chloride, and salts of acetic or other weak acid may replace the sodium fluoride. A solution in which precipitation of a toxic compound is brought about by the evaporation of a volatile component consists in a cupric salt, arsenious acid, and a salt of a volatile organic acid, such as sodium acetate or formate. Cupric arsenite is formed, and a small proportion of the volatile acid is set free. As the latter is evaporated into the atmosphere, more cupric arsenite is formed and precipitated until most or all of the copper is precipitated as arsenite or acetoarsenite. Alternatively, the solution may be prepared by dissolving cupric acetate and arsenious acid, any precipitate formed being redissolved by the addition of acetic acid. The arsenic used in any of the solutions is preferably in the arsenious form, but arsenic acid may be used. The solutions may be used as insecticides and fungicides.
