Abstract: 768,021. Cathode ray storage tubes. ELECTRICAL & MUSICAL INDUSTIRES, Ltd. Sept. 3, 1953 [Sept. 17, 1952], No. 23294/52. Class 39(1). An electronic charge storage tube 1 includes a target electrode 6 comprising a foraminated electrode of electrically conducting material, such as a metal mesh having a 1000 meshes per linear inch, having a coating of photo-conductive material, such as antimony tri-sulphide or cadmium sulphide, at least on one side thereof, means 2, 3, 4 for generating electrons which impinge on the coating to cause charges to be stored thereon, an electron gun 8, 9, 9a generating a beam of electrons for reading the charges applied to the coating, and an electron collecting electrode 5 to collect electrons passing through the target electrode 6, the tube being arranged so that light can be projected on to the photoconductive coating to cause the charges to leak to the conducting material. The electron generating means 2, 3, 4 includes a modulating electrode 3, and an electrostatic grid shield 7 and a mesh ion trap 11, are provided. Scanning coils 12, 13 and a solenoid coil 14 are provided externally of the tube. The electrons from the source 2, 3, 4 have such velocity that a greater number of secondary electrons are released from electrode 6 than are incident thereon so that electrode 6 becomes charged positively, and the electrons from the source 8, 9, 9a have a low velocity. Means for irradiating the photoconductive coating on the electrode 6 with light can be an external circular lamp 19, Fig. 1, an internal ring lamp 20, Fig. 2, a filamentary light source, 22, Fig. 3; comprising a number of parallel wires, which can also act as the collecting electrode, or a C.R.T. 25 producing an electron beam scanned over a fluorescent screen to produce a flying light spot projected by optical system 26 through circular window 27 on to electrode 6.

Title: Fuel injection systems of diesel engines
IPC: F02D1/10
Filed: 1973-05-16
Abstract: 1436384 Fluid-pressure servomotor systems SULZER BROS Ltd 16 May 1973 [31 May 1972] 23371/73 Heading G3P [Also in Division F1] A fuel injection pump 1 of a diesel engine 6 is operable during normal operation to deliver a variable quantity, but depending on the value of a given operating parameter of the engine e.g. the engine speed falling below 60% of normal, adjustment means 36-44 operate to retard the start and end of injection without altering the quantity delivered. During normal operation, as the engine speed increases, a speed controller 23 driven through gearing 32-35 from the pump camshaft L1 causes, via a rod 25, clockwise rotation of a three-armed lever 26 about a fulcrum X. This, in turn, moves rods 30, 31 to cause rotation of levers 17, 18 and eccentric pivot pins 15, 16 thereon. The pins 15, 16 form the fulcrums of levers 13, 14 which control, respectively, the closing and opening of an inlet valve 7 and a spill valve 8, the pins moving so as to advance the closure of the inlet valve 7 and to retard the opening of the spill valve 8. Thus the quantity delivered increases. A controller 50 responsive to engine speed, temperature, combustion pressure or the charging pressure of a supercharger moves a valve 46 to a position in which compressed air from a line 47 is delivered through a line 45 to a cylinder 43 to displace a spring-loaded piston 42. Movement of the piston 42 causes, via linkwork 36-41, shifting of the fulcrum X to a new position X<SP>1</SP> and consequentially a simultaneous retardation of the valves 7, 8 without alteration of the delivery quantity. The valve 46 and the controller 50 may be adapted to provide a stepless servo-controlled retardation of the valves 7,8. In a second embodiment, Fig. 2 (not shown), the pump 1 has a constant injection start in normal operation.

Abstract: 1,260,975. Milk sterilization. ALFA LAVAL AB. 14 May, 1970 [27 May, 1969], No. 23456/ 70. Heading A2D. [Also in Divisions H3 and H5] Microwave heating of liquids, e.g. for the sterilization of milk, is achieved using a nozzle 4 for providing a jet 16 of liquid having a generally annular cross-section, which jet is free from contact with any surface along at least part of its length. An antenna 6 is arranged coaxially with the annular nozzle 4 and a cylindrical casing 7 having a microwave reflecting internal surface. The frequency of the microwaves is chosen to achieve resonance in the space between antenna 6 and casing 7. The heated liquid is cooled at the exit from the casing 7 by cold liquid entering through further inlets 10, 19, and encompassing the heated jet 16. The possibility of the jet of liquid being initially divergent and then convergent is mentioned. The slot forming the nozzle 4 may be of variable width. Differing pressures within and outside the jet may be obtained.

Title: Arrangement for connecting tangential and/or radial distortions in a cathode ray beam
IPC: H01J29/70
Filed: 1955-08-15
Abstract: 801,487. Electromagnets; permanent magnets. RADIO CORPORATION OF AMERICA. Aug. 15, 1955 [Sept. 14, 1954; Dec. 8, 1954 (2)], No. 23498/55. Class 35. [Also in Group XL (a)] A plurality of magnets and pole forming members are mounted adjacent to and around the periphery of the multi-element screen of a C.R.T. to provide an adjustable magnetic field for correcting distortion produced in the scanning deflection. Magnets or electromagnets 50 are arranged to control the electrons in their path from the shadow mask to the multi-dot screen of a colour television tube 14. In Fig. 1, the shadow mask 20 is concentric with the curved screen 18 carrying groups of red, green and blue phosphor dots and controls beams from three guns 24, 26, 28. Two split iron rings 52, 54 encircle the tube periphery and are held by brass or other non-magnetic spacers 56 and brackets. A cylinder of plastic material separates the rings 52, 54 from the tube. The bar magnet 50 (Fig. 6) is held in a clamp 66 which is pivotally movable on a bolt 72 in a soft iron shunt 74 and a plastic supporting block 76. A conical compression spring 82 surrounds the bolt and bears against a groove 84 in the block 76. Soft iron brackets 90, 92 extend between the rings 52, 54 and the block. Rotation of the magnet enables a varying amount of magnetic flux to pass to the rings and corrects rotational and tangential colour dilution of the multidot screen 18. Radial colour dilution is corrected by providing a sectionalized inner pole forming ring 55, 55a (Fig. 11) located between the other two rings 52, 54. The magnet 50 is held on a threaded bolt 66 in its support block 74 and can be moved to bridge either the sections 55, 55a of the inner ring, or the two outer rings 52, 54. It is retractable by screw motions within a keeper block. An alternative to the single permanent magnet is the provision of two ironcored electromagnets bridging the two outer rings and the segment inner ring respectively (Fig. 13, not shown). The two ends of the ring segments 55, 55a may be upturned. In another form the permanent magnets bridge sectionalized parts of two discontinuous pole-forming rings. They may be octagonal or cylindrical and retractable into a keeper ring by means of the screw-threaded engagement of the supporting bolt with a U-spring and hushing (Fig. 16, not shown). Each cylindrical magnet 50 acts in co-operation with segments 52, 52a, 54, 54a which have inturned ends spaced from each other to provide an air gap. When the magnet is fully retracted it is short-circuited by a surrounding ring of magnetic material, but when fully extended or intermediately, field strengths are induced in the sectionalized rings, the polarity of the sections depending on the position of the magnet either longitudinally of or transverse to the rings (Fig. 18).
