Title: Improvements in or relating to Rotary Waveguide Joints
Inventor: KRIGER JACOBUS WILLEM HENDRIK
IPC: H01P1/06
Filed: 1969-03-17
Abstract: 1,188,497. Rotatable waveguide joints. HOLLANDSE SIGNAALAPPARATEN N.V. 17 March, 1969 [20 March, 1968], No. 13942/69. Heading H1W. In a rotary waveguide joint which includes a coaxial line having an outer conductor 1 with an upper part rotatable with respect to the lower part, to which it is coupled by a choke coupler 3, and two rectangular waveguides 4, 5 provided with impedance transformers 6, 7 coupled at right angles to the lower and upper parts, the inner conductor 2 of the coaxial line contains a tube 9 through which a cooling fluid is forced upwards, to return through the space between the tube and the inner conductor after being fed to and from a heat exchanger 11 mounted on a platform which rotates with the outer conductor; the arrangement permits the efficient cooling of elements-e.g. high frequency filters-mounted on the platform. The outer conductor 1 is closed at the top by the end cap 8, to which is attached a cylindrical casing 17 which forms, with cylinder 12 and seals 18 to 21, two chambers 13 and 14, into the upper one of which the inner coolant tube 9 projects, and which are connected, respectively, to the coolant inflow and outflow pipes 15 and 16 for the heat exchanger 11. A duct 25 is provided in casing 17 to permit the escape, and hence indicate the presence of, coolant leaking from chamber 14 due to wear of the seals 20 and 21, the further seal 22 preventing the entry of such coolant into the compartment 24, which contains the ball-bearing 23 for the rotation of the outer conductor 1, the end cap 8, and the casing 17, about the inner conductor 2.

Title: Improvements in and relating to image-production using magnetisable substances
IPC: G11B5/70
Filed: 1965-04-02
Abstract: 1,108,102. Printing plates; magnetic images. AGFA A.G. 2 April, 1965 [4 April, 1964], No. 14069/65. Heading B6C. [Also in Division H1] A magnetic printing form comprises a layer of particles or wires of a hard magnetic substance coated with, or supported in a matrix of, a soft magnetic substance of temperaturedependent permeability, which layer has been subjected to a uniform magnetizing or demagnetizing field and simultaneously to a thermal image of the original. For colour printing groups of different coated particles are used, each group being associated with a particular colour. In Figs. 5 and 6, hard particles 9-12 (having magnetization curves k) with soft coatings 13-16 (having permeability curves m) are associated with Y, R, B and Bk resp.; thus at 70-80‹ C., only Y particles are magnetizable. The image is developed by offering differently coloured inks to the layer consecutively, either at different distances (Fig. 7) or at different temperatures (Fig. 8), or by using inks of different permeability. Colours may be applied in the reverse order from that shown, for transfer printing. For tone printing groups of the same or different hard particles may have the same or different soft coatings or matrix, so that using a single colour ink, the darkest areas are produced when most particles are magnetized. In this case, the permeability of the soft material may vary linearly with temperature (line l in Fig. 6), to produce a gradual temperature effect. Information printing: each group of particles may correspond to an information group, so that information can be printed selectively.

Title: Electrical condenser
IPC: H01G4/04
Filed: 1954-05-18
Abstract: 759,556. Capacitors. ENGINEERING RESEARCH CORPORATION, Ltd. May 18, 1954 [June 11, 1953], No. 14576/54. Class 37. A capacitor for measuring quantities of fluid, e.g. fuel in an aircraft fueltank, has one electrode consisting of a winding of a conducting material, the spacing of the turns of the winding being varied along its length in accordance with the shape of the fluid container, in order to provide a linear variation of capacitance with quantity of fluid. The second electrode may comprise a metal tube surrounding the winding and substantially concentric therewith or it may comprise a second winding the turns of which lie between those of the first winding. Fig. 1 shows a capacitor mounted within an aircraft fuel tank and comprising an outer tubular electrode 4 and an inner electrode consisting of an insulated winding 12 disposed around an aluminium cylinder 9. As can be seen, the spacing of the turns of the winding varies along the length of the capacitor, the spacing being least at that level at which the addition of a given volume of fluid causes the smallest rise in level. Fig. 1a shows the capacitor in greater detail, wherein it will be seen that insulation members 7, 8 are attached to the ends of the tube 4, the cylinder 9 being supported upon the members 7, 8 by the eccentrically disposed shafts 15, 16, so that the cylinder 9 may be rotated about the eccentric axis Z-Z by turning the head 19. This rotation alters the spacing between the electrodes and is used to set initially the capacitance to the desired value. In Fig. 3 (not shown) there is illustrated a modification in which the outer electrodes and the winding have an elliptical section, in which case the capacitance adjustment is effected by rotation of the inner electrode about a central axis. In a further modification, Fig. 5 (not shown), the two electrodes both comprise windings upon a common support, the separation between the windings being constant but the spacing of the turns of each winding varying along the length of the capacitor. A graphical method for determining the required spacing of the turns when the form of the fuel tank is given is described. It is stated that the capacitor may be used for measuring quantities of powdered or finely divided solid materials in addition to liquids.

Filed: 1921-05-27
Abstract: 183,969. Shepherd, B. May 27, 1921. Electrical systems, automatic; track apparatus for stopping trains.-In a system for stopping trains automatically, at least, one track rail has insulated sections; the circuits of train stop coils or signal coils are controlled by the presence of trains on sections ahead or behind the coils to prevent trains from meeting or overtaking others. As shown in Fig. 1, both track rails are in sections, the sections of rail A being connected to one side of the electric supply, the other side of the supply being connected to treadle contacts. The treadle b is connected to train stop coils and thence to a distant section of the rail A<1>. When a train enters the first section, the treadle is depressed but the coil circuits are not complete unless a train is on the distant section. The coils T then raise stops to actuate valves on the engine to apply brakes. In a modification, the coils T operate signals, or each circuit may include one train stop coil and one signal coil. The treadle may be discarded and two coils used on each piece of apparatus so arranged that both must be de-energized to allow the apparatus to operate. In the arrangement shown in Fig. 4, only one rail is in sections and a battery is connected to each section. The signal coils S and train stop coils T are normally energized, but when a train enters a section the coils, two sections ahead and two sections behind, are de-energized, thus preventing another train from meeting or overtaking it. Solenoids may be used to cause lamps to show red or green lights. In another modification, relays are connected across the track rails and connect a high voltage to the train stop coils.
