Abstract: 1304429 Character recognition INTERNATIONAL BUSINESS MACHINES CORP 16 Dec 1970 [31 Dec 1969] 59627/70 Heading G4  In a character recognition system, a feature detector detects features of each of a plurality of character fonts, those for one font then being selected, and a segmentation unit produces a segmentation signal indicating boundary between adjacent characters on receipt of selected feature signals of a first type and inhibits production of a segmentation signal on receipt of selected feature signals of a second type. Video from a flying-spot scanner raster scan is digitized by thresholding and entered into a shift register at which logic circuits detect features. A font selector selects for transmission to a segmentation unit and to recognition logic either a general set of the features or features representative of serif characters or features representative of sans-serif characters, depending on the count of a counter incremented in response to serif features and decremented in response to sans-serif features, subject to occurrence of particular features. The segmentation unit responds to logical combinations (including sequences) of the feature signals sent to it to produce a segmentation (end of character) signal for the recognition logic. If a segmentation signal is not produced within 20 scans of the most recent segmentation signal, an error rescan unit causes rescan of the character from the last segmentation point, with altered threshold in the digitizer. If 20 scans are again passed without a segmentation signal, production of a segmentation signal as above is inhibited and then if a blank scan is detected before the scan count reaches 40 an "early segmentation" signal is produced indicating an invalid segmentation at an earlier point and causing rescanning of the entire line. If, on the other hand, a blank scan is detected at or after 40 scans (double-width character) or at or after 60 (triple-width character), the scan count is saved in a further counter and the scan returns back to the beginning of the character as before, with decrementing of the further counter 2 or 3 times per scan line (for cases 40 and 60 respectively), a count of zero producing a forced segmentation signal. If the character was triple-width, the double-width character remaining after this forced segmentation will be scanned in the normal way, &c. as above. Characters of greater than triple-width could be handled by straight forward extensions to the circuitry, or detection of quadruple-width characters could reject the entire line.

IPC: C01B3/36
Abstract: 780,120. Gaseous mixtures containing carbon monoxide and hydrogen. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Oct. 27, 1955, No. 30722/55. Classes 55 (1) and 55 (2). In a process for preparing gas mixtures containing hydrogen and carbon monoxide by partial combustion of hydrocarbon material in a stream of oxygen in which the hydrocarbon material is atomized and injected in the form of a hollow conical jet coaxially into one end of a cylindrical combustion chamber the length of which is less than five times the diameter, the oxygen stream is introduced at a pressure of at least 3 atmospheres through an opening at the same end of the combustion chamber as the conical jet with a rotary motion about the axis such that two torroidal vortices are formed inside the combustion chamber, causing a rapid mixing of the hydrocarbon material with the oxygen stream and a combustion time less than 4 seconds. The hydrocarbon material which may be high molecular hydrocarbons such as heavy oils or asphalt, or powdered coal is supplied at 7 to an atomizer holder 1 so as to be injected into the combustion chamber 2 in the form of a hollow conical jet. Oxygen entering at 10 passes through tangential slots or nozzles 9 into a chamber 3 and thus passes with a rotary motion through the opening 5 into the chamber 2. The atomizer holder 1 which is mounted in the oxygen chamber 3 may be surrounded by a tube 6 through which a combustible gas entering through inlet 8, may be passed. The oxygen may be supplied in the form of pure oxygen, air, air enriched with oxygen, or a mixture of equal parts by weight of oxygen and steam. Approximately 1.25 kilograms of oxygen are used per kilogram of hydrocarbon and the reaction is carried out at a temperature of 1200-1500‹ C. In an example a high sulphur residual fuel oil with a viscosity of 3500 seconds Redwood I at 37.8‹ C., oxygen and super-heated steam pre-heated to about 400‹ C., there being 85 cubic metres (measured at N.T.P.) of oxygen and 90 kilograms of steam for each 100 kilograms of oil supplied, were passed into the combustion chamber under a pressure of 20 atmospheres and at a temperature of about 1300‹ C. The resulting gas mixture had the following percentages by volume; hydrogen sulphide 0.8, carbon dioxide 11.8, carbon monoxide 37.4, hydrogen 48.1, methane 0.6, and nitrogen 1.3. After quenching with water and passage through a waste heat boiler the gas mixture was scrubbed with water to free the mixture from carbon black and substantially free it from hydrogen sulphide.
Patent GB-2002936-A (GB)
Title: Data transfer systems
IPC: G06F5/14
Filed: 1978-06-16
Abstract: During the transfer of data between a peripheral storage device and a main memory via a peripheral controller, a predictor first-in first-out buffer in data logic 36 in the controller is loaded with a dummy byte each time transfer of a word is requested, requested words being temporarily stored in data first-in first-out buffers in the data logic, a dummy byte being dropped each time a two word byte is unloaded from the data buffer so that the input register of the predictor first-in first-out buffer is emptied. This results in a control signal being sent to indicate that there is room for a new word to be stored. When a command for eg writing on a disc is detected, the central processing unit supplies configuration words defining a disc track location, followed by a main memory address, a range count representing the number of bytes to be transferred and a task word for storage in a scratch pad memory. To effect the operation the configuration words are fetched from memory and stored in a device adaptor 14 for comparison with track information read from the disc. Whilst logic unit 29 searches for a match, bus logic 34 requests data from main memory and 32 bytes are consequently stored in the data buffer with corresponding decrementing of the range count and incrementing of the main memory address. When a match occurs the data is transferred, 16 bytes at a time, to the device adaptor, additional data from main memory being then requested, this process being repeated until the range count is zero. The process of transferring data from disc to main memory is effected by determining the required disc and an offset count then being accessed to determine how many leading bytes are to be ignored before transfer commences (the range count only being decremented when the offset count has been decremented to zero). <IMAGE>
