IPC: G01S3/787
Filed: 1961-02-13
Abstract: 961,984. Infra-red aircraft proximity indicators. AEROJET-GENERAL CORPORATION. Feb. 13, 1961, No. 5322/61. Heading G1A. [Also in Divisions B7 and H4] Aircraft equipment detecting infra-red radiation emitted by, and indicating the direction of, proximate aircraft comprises a scanner 10 and two non-scanning radiation receiving devices 11 and 12, Fig. 1, which give complete spatial coverage, their respective fields of view being bounded by conical surfaces 31, 31a and 32, 32a; 29, 30; and 27, 28. The field of view of scanner 10 embraces 360 degrees in azimuth by the rotation about a vertical axis of an inclined mirror 44, Fig. 2, which deflects incident radiation through a lens 100, a rotating parallel ruled chopper 46, Fig. 5 (not shown), and a further lens 49, on to a detector 50. Whenever the detector is energized its output supplies current to a lamp 120, Fig. 12, which illuminates an aperture 95, Fig. 11, in a disc 92 rotated in synchronism with the mirror of the scanner so as to indicate hearing. As shown in Fig. 6 the radiation receiving device 11 of Fig. 1 comprises a transparent dome 70, a rotating radially divided chopper 79, Fig. 9 (not shown) and two horizontal semi-circular detectors 72, 73 so that radiation from an object 01a above the device and to the right of the vertical plane 125 separating the two detectors 72, 73 is received mainly by the detector 72 and similarly radiation from an object 01b is received mainly by detector 73. The outputs from the detectors 72, 73 are applied respectively to energize pairs of lamps 112, 116 and 111, 115, Fig. 12, the lamps 111 and 112 serving to illuminate left and right arrow signs 130, 131 respectively and an "ABOVE" sign being illuminated by both the lamps 115, 116 so that radiation from the object 01a causes illumination of the right arrow 131 and the "ABOVE" sign whereas radiation from the object 01b causes illumination of the left arrow 130 and the "ABOVE" sign. Similar lamps and arrow signs 132, 133, and a "BELOW" sign, are associated with the device 12 to give an indication of the direction of a radiant source within its field of view.

Title: Improvements in or relating to very short wave radio viewing apparatus
IPC: H01Q3/08
Filed: 1946-02-20
Abstract: 613,862. Radiolocation waveguides. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 20, 1946, No. 5346. Convention date, Feb. 21, 1945. [Classes 40 (v) and 40 (vii)] In a radiolocation system for visibly presenting a scene, the received reflected radio waves are made to form a real image of the scene which is scanned by a pick-up device scanning over a predetermined path in the plane of the image, and the signals derived from the pick-up device are applied to a recorder driven in synchronism with the pick-- up device. The scene is illuminated by radio waves, either by flood-lighting or by a scanning beam, reflected waves being focussed by the mirror 10 on to a crystal detector or waveguide orifice 11. The received signals are amplified and applied to a recording stylus 18 which scans the drum 16 driven by motor 17 helically. The recording system is coupled to the receiving system by means of a pin 23 which causes the pick-up device 11 to scan horizontally once per revolution of the drum and by means of the link 26 which positions the mirror 10 in accordance with the position of the stylus 18. A representation of the scene is formed upon current sensitive paper wrapped around the drum 16. In a pulsed system, a common transmitting and receiving aerial system may be used, and also the receiver may be " gated " so that only objects within a certain range will be presented. In another embodiment for use in an aircraft, an image of the scene is focussed by a lens on to a waveguide orifice which itself scans in one dimension only, scanning in the other dimension being performed by the motion of the aircraft. Reproduction is carried out upon a sheet of sensitive paper which is moved at a speed proportional to that of the aircraft so that a map of the route covered is produced. Waveguides. Fig. 3a illustrates a waveguide joint for use in the embodiment of Fig. 1 so that the waveguide orifice 11 may be able to perform its scanning motion. Plugs 66, 67 provide " steps " which are used to match the rectangular waveguide portions to the circular portions of the joint. Slot 68 and spacing 69 act as a choke to prevent leakage from the joint.

Title: Improvements in or relating to the detection and measurement of water vapour in gases
IPC: G01N22/04
Filed: 1963-02-13
Abstract: 1,078,111. Measuring water vapour in gases. MICROWAUE INSTRUMENTS Ltd., and J. BILBROUGH. May 8, 1964 [Feb. 13, 1963], No. 5861/63. Heading G1N. An apparatus for determining the water vapour content of bakery oven or furnace atmosphere comprises two waveguide arms 12, 14 (Fig. 1) in the form of a magic tee or hybrid junction. The waveguide 14 has holes 20 to admit the gas to be tested while the waveguide 12 contains a reference sample of dry air or inert gas (e.g. argon, nitrogen). A mica plate 21 which is transparent to electromagnetic radiation isolates the test gas from the reference gas. A Klystron valve in a mount 16 injects electromagnetic radiation, at a frequency of between 9,000 and 11,000 Mc/s., into a waveguide arm 10. A crystal detector 27 is mounted on the waveguide junction arm 1, and detects the electrical out of balance of the system and thus compares the phase shift of the reflected waves in the two arms 12, 14, the ends of the arms 12, 14 also 10 and 1 being closed. The output from the detector is fed to a suitable indicating or recording instrument via an amplifier (not shown). In order to obtain an initial balancing of the system a pair of phase shifters 32 are provided and a pair of attenuators 30 are used to obtain an initial zero setting. Instead of a magic tee the use of a hybrid ring, a ferrite circulator or a directional coupler are suggested. In an alternative embodiment particularly for a bakery oven (Fig. 2) the arm 14 has a radiating horn 34 which faces a metal reflector plate 36. The horn has a mica window 38 equipped with an electrical heating element 39 composed of parallel wires arranged so that the wires are at right angles to the electric field of the radiation so as not to interfere therewith. The heater is to prevent condensation on the window. The output of the apparatus may be used to control the water vapour content of the oven. The phase shifter 32 may include a dielectric vane which is automatically adjusted by a servomotor supplied by the out of balance signal from the detector, to restore balance to the system.

Filed: 1970-02-06
Abstract: 1,248,198. Turbines; gas turbine plant. ROLLS-ROYCE Ltd. Feb. 6, 1970, No.5872/70. Headings F1G and F1T. [Also in Division F2] A sealing device for maintaining constant the clearance 7 between two relatively movable portions comprises, when applied to the turbine 2 of a gas turbine engine, means for varying the temperature of gases directed in heat exchange relationship with the stator casing 6 so as to compensate for relative expansion or contraction of the turbine rotor and casing 6. The means comprises four equiangularly spaced air pipes 10 each having an outlet 11 opposite the shrouds 12 of the rotor blades 3. Each pipe 10 communicates via a restriction 13 with a common supply pipe 14 receiving air bled from the engine compressor, the downstream side of restriction 13 connecting via passage 17 with the space below a diaphragm 16 mounted in a chamber 15. The space above diaphragm 16 is vented via pipe 20 and restriction 23 to a pressure which varies with a pressure adjacent the turbine 2. Should the rotor blades 3 expand to a greater extent than casing 6, the size of the clearance 7 between sealing ribs 4 and honeycomb 5 decreases causing a rise in pressure at the outlet ends 11 of pipes 10. The pressure beneath diaphragm 16 thus increases forcing the latter and an attached link 24 upwards to act on a servo device 38 which causes a lever 33 to pivot about a fixed fulcrum 34. The lever 33 is connected to butterfly valves 25, 26 disposed respectively in a duct 27 receiving hot turbine exhaust gases and in a duct 28 receiving cooler air from the compressor. Valve 25 thus opens further and valve 26 closes further to increase the temperature of the gaseous mixture in common manifold 41, the mixture flowing through passages 42, 43 in heat exchange with casing 6 so as to heat the latter causing it to expand and restore the clearance 7 to the desired value. The casing 6 may be divided into four equal segments each of which is separately heated or cooled in dependence upon the pressure in the respective pipe 10 so as to cater for any eccentricity between the casing and the turbine rotor.
