Title: Improvements in or relating to radio direction finders
IPC: G01S3/14
Filed: 1937-12-01
Abstract: 506,743. Directive wireless systems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and KEMP, R. J. Dec. 1, 1937, No. 33253. [Class 40 (v)] In a direction-finding receiver in which the incoming signal is resolved into two mutually-perpendicular components which are applied to two mutually-perpendicular deflecting systems of an indicating oscillograph, the sensitivity of the oscillograph is directly controlled by the signals received on at least one of the directional aerials and is reduced when. the received signal strength increases beyond a predetermined maximum. Sense may be determined without using an additional sense aerial; and lining-up of the two signal channels is effected by the use of a local test aerial. In the Figure, the two signal components picked up by the two pairs of differentially connected vertical aerials N-S, E-W constituting a crossed Adcock system are fed to the deflection plates 8, 8a of the cathode-ray indicator 9 and to the grids of the pentodes 17, 17a through the amplifiers 5, 5a. The H.T. potential for the anode gun 11 of the oscillograph is supplied by the part 16 of the potentiometer 15, 16, the other part 15 being shunted by the anode-cathode spaces of the heavily biassed pentodes 17, 17a. These biasses are such that the valves become conductive on receipt of a signal corresponding to a maximum deflection on the oscillograph screen; and any signal greater than this causes anode current to flow resulting in an increased potential across resistance 16 and a corresponding reduction in the oscillograph sensitivity so that the deflection is maintained constant. In place of the two control valves 17, 17a, a single valve may be used connected to receive signals from one or both of the amplifiers 5, 5a. Instead of providing an additional open aerial for sense determination, the sense is obtained by utilizing the directive system E-W and the open aerial N which is disconnected from the aerial S and earthed through the-phasing resistance 2 by the sense switch SW. On operation of the switch SW, if the true bearing is in the NE or NW quadrants the oscillograph trace will remain in the NE or NW quadrants respectively whereas if the true bearing is in the SE or SW quadrants the trace will move into the NE or NW quadrants respectively. In a modified form of sense switch, Fig. 3 (not shown), the N aerial is switched directly to the grid of the amplifier 5 thus eliminating any phase shift due to the detuning of the coupling transformer 1, 4 caused by switching at the primary coil I as shown in the Figure. In order to line-up the amplitude and phase of the two component deflection voltages, a test oscillator is incorporated in and screened from the receiver proper, the tuning of the oscillator being gang-controlled with the tuning controls of the receiver proper. The oscillator output is fed to a test aerial through a buried concentric cable which extends at 45 to the N-S and E-W aerials.

Abstract: 1287330 Digital transmission; synchronizing MARCONI CO Ltd 23 April 1971 [9 July 1970] 33299/70 Heading H4P  A digital equipment employing a counter 18 as a source on timing pulses has means independent of the counter for continuously monitoring incoming bit signal streams and responsive to a determined number of identifiable bit signal combinations transmitted at the beginning of a stream for resetting the counter in one step to a predetermined count to achieve correct phasing of the counter with respect to the signals. The determined count may be an "all zeroes" condition. Preferably the identifiable combinations are all similar and correspond to a traffic idle signal having the same number of bits as an intelligence character and the means for resetting the counter may comprise a store register having as many stages as bits in one of combinations. A receiver of known type 1 includes main processor 2 receiving clock signals at bit rate from divider 6 also at character rate through a division counter 8; in the embodiment the division ratio n = 10. To synchronize counter 8, received signals are also fed to n = 10 bit register 13 stepping of which is also controlled by divider 6. On receipt of a predetermined bit combination, e.g. a traffic idle signal, detector 14 changes its output to lead 15D and through normally conductive gate 16 to offset three stage counter 17, assumed initially at 00 which gives an output on lead 20 which closes gate 16. Signals on lead 15D also open gate 21 hence signals from division counter 22 move counter 17 forwards. Counter 22 is fed at bit rate through gate 23 also opened when counter 17 is offset. When detector 14 is not detecting a signal, lead 15F is energized hence opens gate 25 hence admitting reverse count signals from counter 22. At full count a signal on lead 26 resets counter 8 to zero. In operation when the first of a plurality of successive idle characters appear in register 13 a signal on line 15D offsets counter 17 which gives a signal on line 20 closing gate 16 and opening gate 23. The signal on lead 15D also opens gate 21. If the next idle signal is detected by 14 at the correct time, gate 21 will pass one forward count to counter 17. If the next idle signal is not detected gate 25 will be open hence counter 17 will receive a reverse count. When counter 17 is full i.e. when the required number of idle characters had been correctly detected, counter 8 is reset in one step to the "all zeroes" condition by a signal over lead 26.

Title: Vertical velocity measuring system
IPC: G01P3/62
Filed: 1959-10-05
Abstract: 899,860. Aircraft instruments. NORTH AMERICAN AVIATION Inc. Oct. 5, 1959 [Oct. 7, 1958], No. 33738/59. Class 40 (1). [Also in Group XXXVI] A system for obtaining an accurate value of the vertical velocity of an object such as an aircraft comprises a vertical velocity meter, means for obtaining an altitude signal therefrom and comparing it with the signal from an altimeter to give a difference signal, means for differentiating the difference signal, and means for adding the difference signal and the differentiated signal to the altitude signal obtained from the velocity meter. By feeding back this composite signal to apply a correcting torque to the vertical velocity meter, cumulative longterm errors are cancelled out. In Fig. 2 an accelerometer comprises a suspended cradle 4 carrying an induction disc 6 rotated by a motor 8. Acceleration along the axis 10 produces an angular displacement of the cradle relative to the frame, a signal being picked off at 13 and demodulated at 5 to give a vertical velocity signal at terminal 7. The remainder of the circuit to be described provides a correction signal to the motor 8 in a sense tending to drive the cradle 4 to a null position.' The vertical velocity signal is further integrated at 11 to give an altitude signal which is combined at 14 with a signal from another altimeter, e.g. of the radar or barometric type. The difference between the two is multiplied by a constant C 2 , and also differentiated and multiplied by another constant C 1 , these two signals being added at 16 and used to provide part of the correcting signal, thus introducing error and rate-of-error components. A second part of the correcting signal is obtained by multiplying the doubly-integrated acceleration signal by a factor 2g 0 /a 0 , to supply a correction for variations in the force of gravity; g 0  represents the value of g at the earth's surface and a 0  the mean radius of the earth. The remaining two parts of the correcting signal are introduced at the summing circuit 13, one being g 0  as defined above, and the other being F z , which equals Vy(#x+#x) - Vx(#y+ #y), where V x  and Vy are the horizontal velocities of the craft with reference to axes x and y of the stabilized platform on which the instrument is mounted, # x and #y are the corresponding components of the angular velocities of the craft, and #y and #y are the components of the earth's angular velocity in inertial space. This signal F z  is obtained from the craft's navigational instruments. The accelerometer shown can be replaced by any velocity member, and either analogue or digital computation can be used.
