Title: Liquid-metering device
Inventor: POWELL GERALD EVERETT
IPC: F23D11/08
Filed: 1959-02-09
Abstract: 910,504. Rotary oil burners. RICARDO & CO. ENGINEERS (1927) Ltd. Feb. 3, 1960 [Feb. 9, 1959], No. 4474/59. Class 75 (1). [Also in Group XXVI] In a liquid fuel burner a metering device comprises a container 24, rotatably mounted about a vertical axis, and means delivering fuel to be metered to the interior of the container at a desired level near the axis of the container, the container having at least one opening 25 through which fuel adjacent the wall of the container which has been raised to a higher level than near the axis is ejected. Oil fuel is supplied through a float-operated valve 2 to a float chamber 1 which communicates with a main chamber 4 through passages 6, 7. A vertical structure 9 supports two self-lubricating bearings 12 in which runs a flow-metering device 13. The device 13 comprises an outer fuel pipe 17, rotated by an electric motor 18 and an inner stationary pipe 27. The upper end of the pipe constituting the container 24 is formed as an inverted conical frustum. A non-rotating vertically movable overflow pipe 27 is located concentrically within the pipe 17 by a helical member 34 and is operated by an adjustable controlrod 29. The helical member is secured to the overflow pipe 27 or may be secured to the fuel pipe 17. A screening member 35 on the lower end of the pipe 27 ensures that aerated oil fuel from the overflow pipe is not drawn into the helical passage. Two or more radial vanes 38 may be mounted in the pipe 17. As the pipe rotates, oil fuel is drawn up the helical passage to the interior of the outlet tube 24, where the surface of the liquid forms a concave meniscus, indicated in broken lines at A. The oil fuel is flung radially outwardly from an annular lip 26, and if the centre of the meniscus lies above the upper end of the overflow pipe 27, which has axial slots forming weirs 30, some of the fuel will flow back into the main chamber 4. The rate of flow of fuel oil depends on the rotational speed of the outlet tube 24, which determines the profile of the meniscus A, and on the vertical height of the weirs 30. The helical member 34 is designed so that for a given rotational speed it supplies at least as much oil as is flung out of the outlet tube 24, the excess flowing over the weirs 30 into the overflow pipe 27. The oil fuel may be delivered direct to a vaporizing type combustion chamber B in which case the lip 26 may be extended and have vanes 39, or it may be collected in a stationary collecting ring C which has a discharge passage Cl. Specification 764,596 is referred to.

Abstract: 1455074 Optical code reading system ESYSTEMS Inc 4 Feb 1974 [1 June 1973 (2)] 05023/74 Heading G4M Light from three zones A1, B, A2 at a reading area passes through a lens to an image intensifier tube 10. The zones A1, A2 are background image areas and zone B is a code image area. The tube deflects electron beams produced by an image on the cathode and supplies the beams to an anode. A coupler 16 transmits light from the anode to a series of light fibre optical bundles 18 which feed a matrix of light responsive sensors 20. Twenty-one areas of the zones are examined (Fig. 5) with eight fibres in each of the seven zones 1B, 2B, 3B, 4B1, 4B2, 5B and 6B feeding a respective one of seven sensors and the corresponding areas 1A1 and 1A2, 2A1 and 2A2 etc. having fibres combined to feed a respective one of seven further sensors. The two sets each of seven sensors feed a respective one of seven circuits each containing a difference amplifier to effectively compare both background zones with a code zone. The difference signals formed from zones 1, 2, 3, 5 and 6 form signals BZ1, BZ2, BZ3, BZ5 and BZ6 respectively. The signals from the two halves of zone 4 are added in amplifier 90 (Fig. 6) to form signal BZ4. Signals Z4U and Z4L from the difference amplifiers 71U and 71L receiving the signals from the two parts of zone 4 are added in amplifier 184 to form a signal Z4. Circuits 74, 75 receive signals Z4, Z3 and 4ZL to form Full Bar Centroid High and Half Bar Centroid High signals. The signals BZ1-BZ6 are used to set flip-flops (Figs. 10A, 10B, not shown) feeding an encoder producing a digital signal indicating the scanning zone through which the lowest portion of a bar code is passing. The digital signal is held in a store and fed to a read only memory which provides a deflection code fed to deflection coils in the tube 10 to centre the data carrying area on the sensor area. The horizontal deflection coils are energized after the first correction so that the initial bar again passes through the viewing window and a counter determines how many horizontal passes are repeated. When the data area is centred the data is read and monitored and the signals FBCH or HBCH feed counters to raise or lower the vertical deflection to compensate for skew.
