Title: Vor systems

Abstract: 1,248,228. Radio navigation. MESSERSCHMITT-BOLKOW BLOHM G.m.b.H. 31 Oct., 1968 [31 Oct., 1967], No. 51688/68. Heading H4D. A conventional VOR phase beacon utilizing a modulated carrier of frequency F radiated from an omnidirectional aerial 1, Fig. 1, and an unmodulated carrier of frequency F radiated from a rotating directional aerial 2 is modified by interrupting the radiation from aerial 2 for a short interval during which an (omnidirectional) aerial 29 radiates a carrier of frequency which differs from F by # f , where # f  is the frequency of frequency modulation of amplitude modulation of the modulated radiation from aerial 1. The spacing between aerials 1 and 29 is preferably two wavelengths. The invention produces " fine " bearing indication at the aircraft receiver in addition to normal (" coarse ") bearing indication; and the interval is sufficiently short to produce no effect on an aircraft equipped with a conventional VOR receiver. Transmitter, Fig. 1.-In the embodiment # f  = 30 Hz, which is also the frequency at which aerial 2 rotates, a tone wheel 11 is driven by the motor 9 which rotates the aerial 2 to provide the 30 Hz modulation frequency for a modulator 12 which produces a 9À96 kHz signal frequency modulated at 30Hz; this signal amplituding carrier F from a frequency multiplier 5. The modulation is removed for the radiation from the aerial 2 by a suppressor 16, and R.F. switch 21 periodically disconnects the signal to the aerial 2. The carrier F - # f  for radiation from the aerial 29 is produced by utilizing the 30 Hz output from a demodulator 39 to trigger an oscillator 22, the frequency and phase of which is maintained constant with respect to the 30 Hz output of the generator 7. The carrier F - # f  is coded from an oscillator 25 by an amplitude modulator 26. Digital control to maintain the constant phase and frequency of the difference # f  may be employed, Fig. 3 (not shown). Receiver, Fig. 3.-The fine bearing measurement is accomplished by comparing the phase of the azimuth-dependent beat with the phase # of the 30 Hz reference frequency from aerial 1 (#α sin #, where # is azimuth angle). Ambiguity is resolved by the conventional coarse measurement. The supplementary apparatus comprises a filter 110 which extracts the coding present during fine measurement to actuate a Schmitt trigger 111 which energizes a lamp 112 and relays 1 13a, 113b, 113c. The 30 Hz reference signal is fed to a resolver 120 and thence via a propeller modulation filter 123 to the phase comparator 125, the other input to which is the 30 Hz beat frequency originating from a demodulator 62; ,the D.C. voltage is converted to A.C. which supplies a servomotor 127 which in turn adjusts the rotor of a differential synchro 128 and the rotor of the resolver 120 until the signals into the phase comparator are in quadrature. The output of the synchro 128 is connected to bearing indicator 107.

[Also in Division E2] A cargo container spreader, Fig. 1 (not shown), has a number of downwardly projecting posts 13 for engagement in corresponding recesses in a container the posts being mounted such that they can be displaced to align with a misaligned container recess. Each post has latching means 15 which, when the post is rotated by means of a ram 16, connecting rod 18 and a cranked lever 19 connected to the post 13 co-operate with the recesses. Each post 13 is rotatably mounted in a casing 21 having a bearing surface 22 for engagement with a container. Upward movement of the easing 21 against the action of a spring 28 surrounding the casing results in the post 13 moving to a position where its longitudinal axis can be displaced to allow the post 13 to enter a misaligned recess (R) in a container as shown in Fig. 4 (not shown). Each post 13 has a safety interlock which prevents its rotation when a container is suspended from the spreader, comprising a cam plate 30 and a sensing rod 31 having an enlarged portion 34, which, in a locked condition, engages the plate 30. On dropping the spreader on to a container, the latching means 15 enters the recess, the rod 31 contacts the container and is moved against a spring 32 to move the portion 34 of rod 31 clear of cam plate 30 thus unlocking the post 13 to permit its rotation. When the container is suspended from the spreader the posts 13 are held in the locked condition.
