Title: Information transmitting system for moving object
IPC: G08G1/0967
Filed: 1966-06-13
Abstract: 1,121,405. Inductive signalling. H. OBATA. 13 June, 1966 [22 June, 1965; 10 Aug., 1965; 20 Sept., 1965], No. 26261/66. Heading H4U. An inductive signalling system comprises a fixed transmitter producing a voice frequency information signal and a control signal whose frequency lies outside the voice frequency band, the resulting composite signal being fed into an inductive loop, and a movable receiver having a pick-up coil co-operating with the loop and a filter for selecting the control signal, the control signal being rectified to operate a relay and render a normally blocked amplifier responsive to the information signal. As described, the system supplies recorded information to road vehicles via transmitting loops on or buried under the road surface or arranged vertically beside the road. In one arrangement, Fig. 4, the pick-up coil 3 feeds a common amplifier 21, the speech and control signals being separated at 22 and the control signal applied via a tuned circuit 23 and diode rectifier 24 to operate a relay 25. Operation of relay 25 changes over a two-way switch 25s in the input circuit of the A.F. amplifier of a conventional oar radio 27... 30 so that the speech signal selected at 22 is fed via amplifier 26, switch 25s and the A.F. amplifier of the car radio to the loud-speaker. The car radio is returned to its normal operation immediately the control signal is removed. In a modification, Fig. 6 (not shown), the transmitter is arranged to transmit selected combinations of three different control signals, e.g. 15 kc./s., 16 kc./s., 17 kc./s., each controlling a separate relay at the receiver. One of the control signals causes the apparatus to operate as previously described, but other combinations select one of a plurality of previously recorded tapes from play-back equipment in the car.

Abstract: 1,020,484. Waveguide directional couplers. FERRANTI Ltd. July 5, 1963 [July 14, 1962], No. 27130/62. Heading H1W. A waveguide directional coupler comprises two parallel rectangular waveguide sections 11, 12 having an effective broad wall 13 in which is provided a single slot 14 located to one side of the axes of the waveguides. In the vicinity of the slot the sections 11, 12 together behave as a single septate guide having a broad dimension equal to more than double the broad dimensions a of either of the sections. The septate guide supports both the TE 01  and TE 02  modes and the dimensions of the slot are such that a 90- degree phase difference between the two modes arises over its length. As a result, energy from one input port is equally divided between two output ports. The dimensions b of the sections are reduced sufficiently to prevent propagation of a TE 10  ridged-waveguide mode over the coupling section. To this end, b is made somewhat less than a quarter of the wavelength of the propagated energy. The slot need not extend (as shown) to the narrow walls of the waveguides.' It may be displaced from these walls by a distance not greater than the narrow dimension b. An alternative form of the coupler in which the guides are spaced apart and do not have a common wall, is described.

Title: Microwave interferometer
Filed: 1963-07-10
Abstract: 1,013,667. Radar. BENDIX CORPORATION. July 10, 1963 [July 12, 1962], No. 27357/63. Heading H4D. In an arrangement for measuring the thickness of a piece 34 the phase of microwave energy radiated on to the upper surface of the piece is compared with the phase of the energy reflected from its lower surface after reflection from the upper surface. Thus accurate thickness measurement of e.g. sheet steel as it passes between radiators 33, 39 is possible despite " flutter " of the steel. In the embodiment the frequency-modulated output of a reflex klystron 25 is fed via a cavity resonator 26 which stabilizes the carrier frequency and affords pulses of energy at 35 Gc/s.; most of this energy is sent via isolator 30 and circulator 31 for radiation by aerial 33 and the rest (" reference " signal) is sent to arm 41B via a calibrated attenuator 42 and a calibrated phase shifter 43 adjusted for a given sheet thickness, deviations from which are to be measured. The first-reflected energy is sent via circulators 31 and 37 to aerial 39. The second-reflection energy passes via circulator 37 to arm 41A of " magic- T " 41 to thereby produce the vector sum of reference and double-reflected signals at arm 41C the output from which is detected by crystal 48. Amplifier 44 amplifies only at the frequency generated by oscillator 24 thereby reducing noise. The vector difference of reference and doubly-reflected signals is formed in arm 41D, is detected by crystal 45 and is passed to amplifier 44. The output of the latter, representing the magnitude of sheet thickness variation, is indicated by a galvanometer 46; the sign of the variation is given by a phase comparator 47. Attenuator 42 and phase shifter 43 are calibrated by placing a sheet of the desired thickness between the aerials. Specification 907,713 is referred to.
