Title: Improvements in instrument landing systems
Inventor: SHEEHAN MICHAEL JOHN RICHARD
IPC: G01S1/02
Filed: 1964-11-24
Abstract: 1,111,567. Radio landing system. ELLIOT BROS. (LONDON) Ltd., and BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. 24 Nov., 1965 [24 Nov.. 1964], No. 47808/64. Heading H4D. In an instrument landing system, of the type wherein a beam 2 of radiation is projected with its centre line along the landing path having a characteristic linearly varying with the angular deviation from the centre line, the lateral sensitivity of the beam, i.e. the change of said characteristic per unit lateral displacement from the centre line of the beam, increases as a detecting aircraft 3 means the transmitting point 1, such that with said lateral sensitivity determining the degree of correction control of the aircraft's auto pilot, said control and aircraft will tend to become unstable near said transmitting point. The invention is intended to overcome this fault and for this purpose provides an auxiliary antenna 6 laterally offset from the main, normal antenna 4 supplying the correcting signals to the auto pilot. The auxiliary antenna 6 is connected to a receiver, Fig. 3 (not shown), which determines the characteristic (in the system described, the difference in depth of modulation of two overlapping beams) and so, since the lateral displacement is constant. provides an indication of the lateral sensitivity of the beam. To compensate for the case where the main antenna 4 is not on the centre line of the beam, the characteristic determined by the main antenna is subtracted from that determined by the auxiliary antenna by a mixing process. The resulting corrected signal is used to correct in an inversely proportional manner, the correction signal fed to the auto pilot. The system is described for both localizer and glide path, overlapping beam systems.

Specified diluents are chlorinated methanes, ethanes and ethylenes and chlorofluorinated ethanes and ethylenes; the diluent(s) are recovered from the reaction unchanged in composition.  Preferably the diluent is a mixture of intermediates, by-products and products of the reaction.  Inert gases such as N2 or Hcl may be present.  The catalyst may be one or more metal oxides or salts, e.g. halides, and may be supported; ThF4 is specified.  The catalyst may be divided into two zones, the first at 250-470 DEG  c. and the second at 300-500 DEG  C.  Examples use THCl4H2O impregnated an alumina, treated with air and then HF.  Main products in examples are CF2Cl.CF2Cl and CF2Cl.CFCl2.ALSO:Catalysts for the production of chlorofluoroethanes from ethylene or ethane, Cl2, HF and a diluent (see Division C2) e.g. ThF4, may be disposed in two zones at different temperatures, e.g. the first at 250 DEG -470 DEG C and the second at 300 DEG -500 DEG C.
Patent GB-495780-A (GB)
Abstract: 495,780. Testing physical qualities of materials. SIEMENS & HALSKE AKTGES. May 18, 1937, Nos. 13897 and 13898. Convention dates, May 18, 1936 and Feb. 10, 1937. [Classes 106 (ii) and 106 (iv)] Comprises an arrangement for measuring the vibratory properties of bodies, wherein a body to be tested is supported upon members, for example wires, which do not appreciably damp the vibrations and at least one of such members is also utilized to impart vibrations to the body and/or to transmit vibrations of the body to vibration measuring apparatus. In Fig. 1, a rod 1 to be tested is suspended by means of wires 2 from an armature 3 disposed between the two poles of a permanent magnet 4 and surrounded by a coil 5 in which an A.C. is produced upon movement of the armature, the current being fed to a measuring instrument 7 through an amplifier 6. The exciter comprises a yielding armature 8 arranged between poles, as shown, to the centre of which is connected a rod 9. A low-resistance coil 10 surrounds the armature and is fed from an audible frequency generator, not shown. When the coil is excited, the arm 8 vibrates by bending as a result of which the rod 9 oscillates longitudinally and transmits the oscillations by wires 11 to the rod 1. In Figs. 2, 3, a receiver is coupled back to the exciter through an amplifier so that a special generator is not required. By means of a variable condenser 12 the tuning may be so selected that different harmonic vibrations are set up. In Fig. 3, it is possible to vary the degree of coupling between the receiver end of the amplifier and the exciter by a potentiometer 13. In the form shown in Fig. 2, the natural frequency is measured by comparison with a sound transmitter by observation of the beats. In another form, the rod is arranged horizontally and suspended at two points by wires. When the body tested is very large, it may be supported at the nodes so that the wires do not take any part of the weight of the body. Natural oscillations of the supporting members may be damped out at one or more points by cotton wire &c. The test may be carried out at high temperatures, the members connecting the vibrator and receiver to the body and also the vibrator and receiver being suitably screened from the heat.

Title: Heat electrical power transducer
IPC: H02N3/00
Filed: 1966-11-07
Abstract: 1,100,983. E.H.D. generators. A.M. MARKS. 7 Nov., 1966, No. 49798/66. Heading H2A. In an E.H.D. generator employing a charged aerosol as working medium, an efficiency approaching that of the ideal Carnot cycle is achieved by employing a large ratio of liquid mass to gas mass in the isothermal phases and a small ratio of liquid mass to gas mass during the adiabatic phases of the cycle. Heat may be injected isothermally into the working medium simultaneously with the extraction of electric power. The liquid component of the aerosol is used for heat-transfer. When the liquid component is large, most of the heat resides in the liquid which can thus maintain the carrier gas at uniform temperature, producing isothermal working. Similarly, when the liquid content is low, adiabatic working is achieved. Liquid may be sprayed in to increase its proportion and subsequently removed by standing or by centrifuging in the discharging region. The ratio of liquid mass to gas mass varies from 10 to 0À01. The aerosol is simultaneously charged and formed by forcing liquid 21 out of a capillary tube 20 whose tip is charged or is adjacent a charging ring 25 whose field assists in accelerating the droplets to the velocity of the carrier gas stream 22. The kinetic energy of the droplets and gas is turned into electrical energy in the conversion space 30, this energy being withdrawn in the collector 31 and fed out at lead 32 to load 33. It is described (Fig. 3, not shown), how a battery of capillaries associated with charging screens may be used. A single loop circuit for recirculating both gas and liquid in the necessary temperature cycle, is described (Fig. 2, not shown). A multistage system in which the heat rejected from one cycle is used in a following cycle of lower temperature, is also described (Fig. 3, not shown). The use of a heat-exchanger is avoided by transferring the liquid directly from one cycle to the next. Suitable working substances are water-steam or air; and galliumnitrogen.
