Title: Character recognition systems
IPC: G06V10/98
Filed: 1972-06-02
Abstract: 1393455 Character recognition systems OPTICAL RECOGNITION SYSTEMS Inc 2 June 1972 [2 May 1972] 25766/72 Heading G4R A character recognition system includes an optical scanner and a scanner responsive to characters printed in magnetic ink. The scanners provide signals relating to the same character to respective recognition units whose outputs pass to a check unit which provides an output character or a reject signal dependent on the signals fed to it. The check unit output controls a printer and magnetic tape recorder. The characters may be stylized or coded. The check unit provides the following functions: (a) if the output character, e.g. A, of the optical recognition unit OCR is the same as that of the magnetic recognition unit MICR the check unit outputs character A; (b) if MICR outputs a character A and OCR outputs a reject signal indicating lack of recognition, or vice versa, the check unit outputs an A; (c) if MICR outputs a character A or a reject signal; and OCR gives no output because the scanner detects no character, or vice versa, the check unit outputs the character A or a reject signal. (d) if MICR outputs a character A and OCR a character B the check unit operates in one of the following ways: (1) it gives a reject signal; (2) by taking account of the field within which the character being scanned lies, as determined by sensing field-defining marks, the output of one or other of the recognition units is rejected as being less likely to be correct. For example, the OCR unit may be suppressed when a character in a field likely to be interfered with by handwriting is being scanned; (3) if the two characters are such that it is known that the output of one recognition unit is more likely to be correct than that of the other unit then the output of the first unit is selected as the output of the check unit. For example, if MICR output 0 and OCR outputs 8 the MICR output is chosen since the optical scanner may be detecting a 0 mutilated by a horizontal marking. In an alternative arrangement the check unit provides a reject signal whenever the MICR and OCR do not output the same character.

Abstract: 425,903. Preserving fruit &c. RYAN, J. T. S., 1, Hyde Brae Street, Strathfield, near Sydney, Australia. Sept. 19, 1933, No. 25858. Convention date, May 31. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 29, 1934.] [Class 49] In preserving fresh fruit and other perishable foodstuffs by keeping them in an atmosphere of gases resulting from the combustion of a carbonaceous fuel in air, for example ship's flue gas, and consisting of oxygen, carbon dioxide and nitrogen with or without other inactive or inert gases, the gas mixture being kept at about 40-80‹ F. and periodically or continuously replenished, the atmosphere is humidified to prevent vaporization of moisture from the foodstuffs. The gas mixture used may contain 8 per cent by volume of oxygen, 12 per cent of carbon dioxide and the remainder nitrogen with or without other inactive or inert gases. The food is placed in a chamber 22 which is supplied with flue gas drawn by a fan 20 from a flue 5 through a valve 7, a wire mesh or like strainer 9, a cooler 6, which may consist of a multiplicity of ducts for circulation of water, brine, or other cooling fluid with tortuous passages between, and a scrubber 15 consisting of corrugated laminae covered by a film of oil and positioned close together, the gas passing between the laminae and the suspended matter therein adhering to the oil. The gas passes into the chamber 22 through a valve 21 and a sample can be drawn off through a pipe 28 and a valve 29. The chamber 22 is lagged or otherwise heat insulated and is substantially gas-tight and has outlet pipes 23, 24 with valves 25, 26 and can be exhausted by a fan 27. The humidification of the atmosphere is effected by placing in the chamber 22 vessels containing water which may be distilled or otherwise freed from micro-organisms, the humidity preferably being near to the saturation point, e.g. a relative humidity of 90-97 per cent. The gas mixture may be periodically exhausted from the chamber and replenished or may be continuously circulated through the chamber. When the contents of the chamber are to be removed the chamber is flushed with air by closing valve 21 and opening valves 25, 26 and operating fan 27. Specification 14552/85, [Class 49], is referred to.

Patent GB-1062588-A (GB)
Title: Improvements relating to electronic yarn clearers
IPC: B65H63/06
Filed: 1964-06-24
Abstract: The sensitivity of clearing apparatus (or a series thereof) wherein each unacceptable fault e.g. enlarged portion, in a running yarn is detected and removed by a cutter, is automatically regulated so that the mean value of the actual number of breaks per unit time is equated to a nominal (predetermined and adjustable) value.  In one apparatus, the tapping arm of a potentiometer (whence a control signal determining the degree of clearing is derived) is moved by a step-by-step motor which is rotated in one direction by impulses from a time-constant transmitter e.g. an adjustable, astable multivibrator, and in the other direction by impulses generated by energisation of the operating solenoid of the cutter mechanism (consequent on passage of a yarn fault through a detector rendering a transistor conductive) until a state of equilibrium is attained.  In a modification, the two series of opposed impulses are converted e.g. by solenoid actuated pawl and ratchet mechanisms, to rotary movements which are combined in a differential the output shaft (or carriage) of which moves the potentiometer arm.  All the mechanical drives may incorporate adjustable reduction gears to vary the sensitivity and response of the apparatus according to the operating e.g. winding, conditions.

IPC: B05B7/08
Filed: 1945-10-09
Abstract: <PICT:0602826/III/1> <PICT:0602826/III/2> <PICT:0602826/III/3> A paint-spraying device comprises a body, an elongated fluid-receiving chamber in the forward end of said body, a discharge tip communicating with said chamber and extending forwardly thereof, said tip terminating in a discharge orifice, a plurality of paint supply inlets communicating with said chamber and disposed in the forward end of said body, the central longitudinal axis of each of said inlets being at an angle to the central longitudinal axis of said chamber, said inlets being spaced from each other, a pair of air passages in said body, a housing surrounding said tip and connected to the forward end of the body, the housing having an opening therein taking the orifice end of the tip and the tip having slots communicating with one of the air passageways.  Referring to the drawings, tanks 151 and 152 containing paint under pressure are connected via tubes 165 and 158 to the spray device shown in Fig. 1. The paint from tank 151 moves under pressure through piping 160, 161, valve 162, hose 165 and front passageways 77 and 69 into chamber 68. The paint from tank 152 moves under pressure through piping 167, 155, valve 156, hose 158 and rear passageways 77 and 70 into chamber 68. Air under pressure moves through hose 198 and passageway 13 into chamber 15.  Trigger 38 is drawn manually towards handle 13 and so strikes the rod 24 unseating valve 23 and so allows the air to pass into chamber 15 into chamber 16, through passages 18, 19, 108 and 110 into chamber 140 and through passages 29 and 128.  The air also passes from chamber 16 through passages 20, valve 33, passages 32, 109, 113, slot 100, openings 101, slots 93, 102, chamber 132 and then between the outside of the nose of fluid tip 90 and orifice 124.  The trigger 38 then strikes nose 58, retracting valve rod 50 to open the fluid discharge orifice 97 at the end of the common fluid-receiving chamber formed by the aligned chamber 68 and the chamber in said fluid tip 90.  The fluids, which may be differently coloured paints, discharge out of orifice 97 and are atomised and mixed by the eddying currents formed by the passage of air through orifice 124 and then are further mixed by passing through air jets from openings 128.  On release of the trigger, orifice 97 is closed by valve rod 50 operated by coiled springs 65 and 66 and then valve 22 is closed by rod 24 operated by spring 28.  The liquids entering the chamber 16 and passing out of the orifice are in contact with each other for such a very short period that they leave the orifice before forming a homogeneous fluid, hence producing a coloured spattered surface.  By employing paints of differing viscosity, the high viscosity paint being led through conduit 165 and the low viscosity through conduit 158, attractive patterned effects may be produced.
