Title: Improvements in or relating to conveyor systems
Inventor: PEARSON ARTHUR WILLIAM
IPC: B61B10/00
Filed: 1956-07-20
Abstract: 865,703. Conveyers for delivering goods at predetermined positions. ELECTRIC & MUSICAL INDUSTRIES Ltd. July 22, 1957 [July 20, 1956], No. 22470/56. Classes 78 (1) and 104 (2). In a conveyer system consisting of a plurality of load-carriers 4 adapted to be temporarily or permanently coupled to a driven chain 2, each carrier is provided with one or more magnetizable members and means are provided for selectively magnetizing the member or members at one point along the conveyer to record a datum or data thereon relating to the carrier or a load carried thereby, and for reading the datum or data at another point along the conveyer, e.g. to operate an indicating device or to operate means for routing the carriers according to the data. In the embodiment shown, each carrier is in the form of a plate 7 depending from a transverse member 8 carrying rollers 11 engaging lower U-section tracks 3. An upstanding member 12 on the plate 8 carries a further order piece 13 arranged so that the flanges of the tracks 3 pass between the plate 8 and the piece 13 to guide the carriers. A hole 14 in the plate 7 provides for the attachment of articles to the plate 7. The carriers are propelled by dogs (not shown) on a driving-chain 2 having rollers 6 running in U-section tracks 1. A number of magnetizable members are provided in the form of mild-steel bars 15. A magnet core 16 on which is wound an energizing coil 18 is disposed around and secured to the tracks 1 and 3 for magnetizing the bars 15 to different degrees of or/and in different directions of magnetization as they pass between the polepieces 17 of the core, the coil current being controlled by an operator. Instead of being secured to the tracks the core may be movable along the tracks with each carrier during magnetizing of a bar, being returned to its initial position by a spring. A number of such movable cores secured side-by-side may be used for simultaneously magnetizing all the bars. The data so recorded on the bars is read by either a single sensing coil 24 or by a number of such coils 20 secured on a sliding bracket 21 adapted to be moved by a carrier for a short distance and then returned by a spring 23, this return movement producing a voltage in the coils 20 corresponding to the magnetization of the various bars. In another form a magnetizable member is formed by a strip of magnetic recording tape secured along one side of the plate. The magnetization is effected by a recording-head and a reproducing head is used to read the recorded data.

Title: Superfast thermalization of plasma
IPC: H05H1/22
Filed: 1961-06-23
Abstract: 920,316. Thermonuclear apparatus. UNITED STATES ATOMIC ENERGY COMMISSION. June 23, 1961 [June 5, 1960], No. 22845/61. Class 39 (4). A method of heating plasma to high kinetic temperatures in an axially symmetrical magnetic containment field established in an evacuated space, comprises generating rotating rings of plasma at the opposite ends of the containment field and accelerating the rings towards each other while increasing their kinetic energy so that the rings collide within the containment field and their kinetic energy is converted into heat in the resulting plasma mass. The method may be applied to an "Astron" type of apparatus wherein an electron layer 10 is established inside a cylindrical container 26 by means of an electron accelerator 37 and injection coils 32, 33, 34. At each end of the container is a plasma gun comprising concentric annular electrodes 41, 42 between which a pulse is applied. A longitudinal magnetic field produced by coils 50, 51 causes gas, admitted through conduit 53 and ionized by the discharge, to rotate as a disc about the axis of the chamber. Each plasma gun is provided with an annular passage communicating with the container 26 through an aperture which can be closed by a magnetically operated valve, the aperture having the same radius as the initial radius of the electron layer 10. The internal wall 58 of the annular passage is of high permeability material and the outer wall is surrounded by a coil 74 so that a radial magnetic field can be established across the end of the passage. A shock coil 69 is provided at the end of each plasma gun to drive the plasma out of the gun. Container 26 is surrounded by a coil 27 and associated mirror coils 29, 31 and by a further coil 77 and associated mirror coils 78, 79. In operation, coils 27, 29 and 31 are energized, the electron layer established, coils 50 and 51 are energized and a pulse is applied to the electrodes of the plasma guns to establish a rotating plasma, e.g. of deuterium, in them. Shock coils 69 are energized to drive out the plasma, and shortly afterwards the valves between the plasma guns and the central container are opened. As the rotating plasma passes through the radial magnetic field as the end of the plasma gun, pinch forces compress the plasma into rotating rings which are accelerated towards each other into the electron layer at supersonic speeds. Coils 77, 78, 79 and the coils 81, 82 at each end of the apparatus are then energized to compress the plasma rings and the electron layer. Specifications 886,404 and 898,503 are referred to.

Title: Improvements in or relating to frequency multipliers utilising electron-velocity-modulation
IPC: H01J25/12
Filed: 1946-08-01
Abstract: 614,822. Velocity-modulated tubes. SPERRY GYROSCOPE CO., Inc. Aug. 1, 1946, No. 22996. Convention date, Aug. 9, 1945. [Class 39 (i)] A frequency-multiplier comprises at least three cavity resonators 11, 32, 52 of different frequencies arranged for successive traversal by an electron beam from a cathode 66, which passes through an accelerating grid 67, then through the pairs of grids 18 and 19, 39 and 41, 57 and 58 associated with the respective resonators, said pairs of grids being separated by drift tubes 14 and 34, and finally through a secondary electron suppressing grid 64 to a collector 63. Capacity defining members 21, 22 enable the physical size of resonator 11 to be reduced, and resonator 32 has a similar feature. Resonator 11 is energized at its fundamental frequency from a source 73 via a coaxial conductor 31 and a coupling loop 29. The frequency of the second resonator is a harmonic of the frequency of the first, and the third is similarly tuned to a harmonic of the second. Energy at the final frequency is extracted from the last resonator 52 by a coupling loop 74 and output line 76. A line 51 and loop 49 may be used to extract energy from the intermediate resonator, but is normally left floating. End wall 17 of resonator 11 contains a flexible diaphragm 23, an arrangement of screws 27 and compression springs 26 constituting a tuning device. The other resonators are also tuned by similar screw and spring devices. The first pair of electrodes or grids 18, 19, where the beam is velocity modulated, may be associated with an external tuned circuit instead of a cavity resonator, as may the other pairs of grids. Specification 530,785 is referred to.

Title: Electric motor-driven pump arrangement for vacuum extraction apparatus for child-birth
IPC: A61B17/44
Filed: 1961-06-27
Abstract: 927,569. Vacuum pump assembly. K. SOBEL. June 27, 1961 [June 28, 1960; Sept. 14, 1960], No. 23183/61. Class 8(1). A suction hose 5, Fig. 2, by which an electric motor-driven vacuum pump 8 is connected to a pelotte 1 has a plurality of branch ducts 51-54 in parallel and of increasing order of flow resistance and each containing a hand adjustable needle valve 62-65 and terminating in a valve which when open connects its associated branch duct to ambient atmosphere thus limiting the degree of vacuum in the hose 5 and pelotte 1; the maximum vacuum being when the ends of all the branch ducts are closed. As shown the branch ducts terminate in a single multi-way cock the plug 55 of which has a central bore 56 which registers with one or other of the branch ducts or is closed by the valve casing. The position of the valve cock may be indicated by a set of signal lamps and the cock may be operated electrically according to a previously set time table. In a modification branch ducts 22 - - 25, Fig. 1, of increasing order of flow resistance and including needle valves 34 - - 37 terminate in solenoid valves 18 - - 21 associated with switches 14 - - 17 mounted on a desk panel 13 and with signal lamps 29 - - 32. The electrical circuit is such that on operating any one of the switches 14 - - 17 the remaining switches are automatically opened and on closing a switch 26 all switches 14 - - 17 are opened and hence valves 18 - - 21 are closed allowing maximum vacuum to be obtained in the pelotte. The time interval elapsing before the vacuum in the pelotte reaches the value determined by the chosen valve may be delayed by allowing the pump 8 to draw additional air from a tank 43 connected to the hose 5 by a duct 42 containing a needle valve 46 and solenoid valve 45 in circuit with a panel lamp 48 and switch 44. The electrical circuit includes a main switch 10 and the vacuum circuit includes a vessel 6 and gauge 27.

Abstract: 632,751. Dough-dividing machines. PALMER, A. R., and BAKER PERKINS, Ltd. Aug. 21, 1947, No. 23216. [Class 87 (ii)] The vertically reciprocating head 1, carrying the measuring pockets 17 into which dough in the hopper 5 is fed by the ram 19, has lateral flanges 2 sliding in guideways formed by the adjacent machined face 4 of the cam chamber and hopper and wedge shaped rails 9. The rails 9 are constantly and resiliently urged against the flanges 2 by wedges 10 bearing on their rear faces against backing flanges 8 on the machine frame. The wedges are urged downwards by springs 22 abutting brackets 20 adjustably mounted on the machine frame and the rails 9 are prevented from vertical movement by pegs 13 secured in the backing flanges 8 and passing through elongated slots 16 in the wedges 10. The wedges 10 take up wear, on the sliding surfaces of the flanges 2 and the guides thus ensuring an airtight seal for the cam chamber 18. The wedge angle is small enough to avoid upward movement of the wedges 10 due to the pressure of the ram.

[Also in Group XX] In a galvanometer or like instrument in which readings are taken by means of an image of an illuminated object formed on a scale by an optical system after reflection by a rotary reflecting portion of the instrument, a concave spherical or cylindrical mirror is disposed in the optical path between the rotary reflector and the scale and is so dimensioned that its radius of curvature is greater than that of the focus of the real image which would be formed by the optical system and the reflector were the mirror absent. As shown light from a source 1 illuminates by a condenser 3, or slot 2, light from which is projected by a lens 6 on to a plane mirror 4 rotatable about an axis 5, and thence passes to a concave cylindrical mirror 8 which forms an image of the slot 2 on a cylindrical scale 10 forming one wall of the casing 12 of the instrument. The cylinder axes of the mirror 8 and scale 10 are parallel, and co-planar with the axis 5 which, in a modification, may also be parallel to the said cylinder axes. The scale may be flat or convex and data for the dimensions of various modifications are given in which, for a particular viewing distance, the image appears equally bright at all positions on the scale.
