Title: Improvements in or relating to methods and/or apparatus for ascertaining distance
IPC: G01S13/36
Filed: 1936-01-29
Abstract: 472,891. Measuring distances by reflected electric waves; phase-difference measurements. FERRANTI, Ltd., and ATKINSON, S. Jan. 29, 1936, No. 2627. [Class 37] The distance between two bodies, for example, the height of an aeroplane, is determined by transmitting radio-frequency waves of constant frequency from the aeroplane and receiving a reflected wave-motion on a separate receiver, the wavelength being greater than twice the maximum distance to be measured, and the received wave motion being mixed with part of the wave motion obtained directly from the transmitter, the resultant output being measured in terms of a phase-difference characteristic. The receiver and transmitter preferably both include beam aerials, the generated wave motion being superimposed upon the ultra short-wave system employed as a carrier wave. A master oscillator 1 is connected to transmitting apparatus 3, 4 through an amplifier 2, the reflected wave being received at 7, 12 and fed to amplifiers 8, 9. The output of amplifier 2 is connected to another amplifier 5, and phase-shifter 6, an automatic voltage control unit F being connected to amplifier 5. The receiver is associated with an amplitude equalizer B, mixer C, rectifier D and failure indicating unit E. After demodulation, a part of the master oscillator frequency wave is fed to anode 14 of double diode 13, the D.C. potential across resistances 22, 23 being used to bias amplifier 8. The amount of bias is determined by a delay voltage produced across resistor 19 by a part of the master frequency output supplied through the phase-shifter 6 and transformer 26, 25 to the second diode anode 24. The arrangement is such that the amplitudes of signals applied by way of amplifier 8 to grid 10 of triode 11, and by way of phase-shifter 6 to grid 28 of triode 27 are equal. The mixed wave motions are fed to rectifier 35 and the D.C. component supplies a moving coil meter 38 which, in the case of an altitude meter, is calibrated in feet. Maintenance of equality in amplitudes is obtained automatically by feeding part of the output of the phase-shifter 6 to a rectifier 43, the D.C. component being used to bias amplifier 5 by way of resistor 52. In case of failure of any of the main parts of the circuits, no bias is applied to grid 41 of triode 40 and an alarm 42 is actuated. A single mixer valve may be employed for the two triodes 11, 27, and a manually operated potentiometer may be used to bias the diode 43. Amplifier 8 may be of the type described in Specification 467,332, [Group XL]. U.S.A. Specification 1,982,271, also is referred to.

Title: Modulator system for micro-positioning transducer
IPC: G08C19/38
Filed: 1958-01-28
Abstract: 874,088. Electric measuring systems. CANADIAN WESTINGHOUSE CO. Ltd. Jan. 28, 1958 [Feb. 22, 1957], No. 2826/58. Class 40 (1). In a system for measuring linear displacement utilizing a transducer consisting of oppositely energized input elements and an output element normally centrally located with respect to the input elements e.g. an E-type transformer, the sensitivity is increased, without errors due to phase distortion by using an L.F. modulated H.F. carrier energizing voltage. As shown (Fig. 2) the output from an H.F. oscillator 11 is modulated at a low frequency at 12 and the carrier suppressed to give two similar outputs A, B in which the carrier waves are 180 degrees out of phase. These signals are fed to the input elements of a transducer 13 whose output, consisting of a signal in phase with A or B depending on the direction of the displacement, is mixed with part of the output of oscillator 11 and fed to a detector 15 to produce a phase-sensitive L.F. signal indicative of the extent and direction of displacement. Specifications 843,816 and 843,817 are referred to.

Abstract: 1416117 Waveguide Joints INDUSTRIE PIRELLI SpA 24 Jan 1974 [2 Feb 1973] 03284/74 Heading H1W A flanged sleeve is accurately located about the end of a flexible waveguide by means of a cylindrical mandrel inserted into the end of the waveguide and firmly located therein by radial pressure against the internal wall. The waveguide consists conventionally of a helical winding 1 surrounded by a flexible sheath 2. The mandrel comprises an internal rotatable, threaded spindle 5 and an outer sleeve 8 carrying a frusto-conical portion 12. Rotation of the spindle 5 causes axial movement of a frusto-conical cap 14 and consequent radial movement of a slotted expansion member 18 which has an outer cylindrical surface engaging the winding 1 and an inner surface having portions complementary to the parts 12, 14. The mandrel is thus accurately located with its axis coincident to that of the waveguide. Thereafter, a flanged conical sleeve 32 is accurately located about the end of the waveguide by a support sleeve 37 having a cylindrical portion engaging the outer surface 30 of the mandrel and a flange 36 engaging a complementary part of the sleeve 32. The support sleeve 37 is axially adjustable by means of a collar 38 threaded on the mandrel. A two-part flange 33, 33<SP>1</SP> containing a sealing ring 34 supports the outer end of the conical sleeve 32. The space between the conical sleeve 32 and the sheath 2 is filled with, e.g. epoxide resin filler. After this has set, a spacer 29 is removed and the sleeve 32 pulled towards the flange 33, 33<SP>1</SP> (by bolts, not shown) to engage the sleeve tightly with the filler. Thereafter, the support sleeve 37 is removed and the end faces of the waveguide, the filling and the sleeve 32 accurately milled to provide a joining face for engagement with a similar face on a further waveguide section (Fig. 4) or on another waveguide component. The milling machine is accurately located upon the mandrel 8. Fig. 4 shows a joint between two flexible waveguides prepared as above. A spcing ring 41 between the bolted flanges contains annular seals 42.
