Abstract: 1,016,892. Gyromagnetic resonance apparatus. VARIAN ASSOCIATES. Aug. 8, 1962 [Aug. 14,1961], No. 30449/62. Heading G1N. In a sideband system i.e. one wherein the  LARMOR constant γ= Wo/Ho is modulated at a frequency W m  to produce signals (W 0  + n W m ) and the precession frequency W A  is equal to γH 0  + γH m . Cos (W m . t) and in which the modulation frequency W m  is automatically adjusted to maintain resonance, the current through the modulating coils 17, 32, Fig. 1, is made to vary directly as the frequency W m  in order to maintain constant the modulation index, in spite of variations with frequency in the inductive impedance of the coils, by the inclusion of circuit elements such as capacitor 37 having a frequency dependent impedance, between field modulator 22 the output of which is maintained constant by A. G. C., and modulating coils 17, 32. The system includes sample 11 under test, and a reference sample 12, between the magnet poles 13, the reference sample being included in a side-band oscillator and serving to determine the modulation frequency. A second output from the reference control receiver serves to control a variable reactor in the circuit of R F transmitter 15 to compensate for drift in magnetic field; Ho. The signal from the test sample is compared with the modulation frequency in a phase discriminator 21 and the resulting D.C. output is applied to a recorder 23 which is driven, in synchronism with the sweep of the field Ho, by sweep control 25. An alternative arrangement of circuit elements in the feed to the modulation coils 17, 32 is described with reference to Fig. 2 (not shown) and comprises a series resistor and a shunt arrangement of a capacitor and resistor in series which is also used to provide a variable proportion of the modulation output to the A. G. C device 36.

Filed: 1962-08-09
Abstract: 1,018,331. Electronic computers. SCAM INSTRUMENT CORPORATION. Aug. 9, 1962 [Aug. 10, 1961], No. 30567/62. Heading G4A. In a priority interrupt system signals on different lines representing programmes of different priorities operate control means including a circulating store 33 (Fig. 2, not shown), for the signals on each of the lines to represent the presence or absence of a signal or the initiation but non-completion of a programme such that the control means initiates the programme of highest priority. Programme demands are made by way of a patchboard 30 having input both from external switches and from within the machine as pseudo-interrupt signals. The demand lines are scanned at odd times T1-T30 by way of sampling gates 34 to give sequential output pulses to a status gate circuit 40 according to the presence or absence of a demand. The presence of a priority demand signal sets an " A " marker in an interrupt register 33 comprising two pairs of bi-stable shift elements separated by nickel delay lines providing no " R " or " B " marker representing the initiation but non-completion of a programme is present. Manually actuated demand signals " C " are similarly scanned at odd times T1-T30 by sampling gates 36 and a " C " marker is set in the interrupt register after the switch is released. The " C " demand signals may be grouped into a selected few of priority levels P1-P15 by gates and registers 38 and applied to the priority level demand signal terminals on the patchboard 30 if other " C " markers are already present in the interrupt register 33. If no appropriate group markers are present a " C " marker is set in the interrupt register 33. The contents of the interrupt register 33 are scanned by priority scanner 42 during odd times T31-T59 and that programme having the highest priority with the corresponding " R " bit absent is initiated if no higher priority programme is in progress. If a second demand appears before completion of a programme a " B " marker is set in the interrupt register 33 and when the programme is completed the " B " marker is reset and an " A " marker is set. Lamps in an " R " bit indicator 46 are set by monostable circuits to indicate those " R " bits set, the monostable circuit having a set time longer than its actual actuation to ease viewing of the light. The computed results are converted to decimal form for visual display or output to a typewriter.

[Also in Group XL (c)] An electrical calculating system comprises apparatus generating signals corresponding to instantaneous range and bearing of a simulated aircraft. It is shown mathematically with reference to Fig. 1 that where X, Y are the cartesian components of ground velocity of the target; W, # the wind speed and bearing; Va, a the target's airspeed and heading; R, # the polar co-ordinates of the target referred to origin O. Va, α, #, W are set by manual controls 1, 2, 3, 4 respectively, Fig. 2, on linear potentiometers P 1 , P 2 , and resolvers S 1 , S 2 , so that voltages representing Va and W are applied from P 1  and P 2  to resolvers S 1  and S 2  which may be sine-cosine potentiometers or magslip resolvers. It is preferred to drive S 1  through a variable-speed motor to facilitate the setting of various rates of turn of an aircraft by the manual control. The outputs of S 1  and S 2  corresponding to Va sin α, Va cos α and W sin #, W cos # are applied, as shown, to summing circuits A 1  and A 2  to produce voltages X and Y respectively, these are fed to resolvers S 3  and S 4 , respectively, together with feed-back information corresponding to the instantaneous bearing # of the aircraft applied by means of a mechanical linkage. Produced voltages X cos # and Y sin # are applied to a subtracting circuit B to produce a signal representing R# and produced voltages X sin # and Y cos # are fed to summing circuit A 3  to produce R. Voltage R is then applied to an integrator circuit I 2  with an input voltage R 0  to produce a voltage R, this voltage R is fed to a divider circuit D with R# to produce voltage 6 which is applied with input voltage representing # 0  to integrator circuit I 1  to produce voltage #; R 0 , # 0  corresponding to an initial range and bearing of the simulated aircraft. Voltage # is fed to a gate signal generator G 1 , with a varying voltage from an aerial rotation simulator Ae so that when the angular position of the simulated aerial coincides with the angle 6 a pulse is supplied to gate circuit G 2 . Voltage R is applied to a phantastron delay circuit P to produce a pulse corresponding in time to the instantaneous range of the simulated aircraft, this pulse is applied to the gate at G 2  so that at coincidence with a pulse from G 1  a signal is supplied to the P.P.I. display unit which produces mark on the P.P.I. tube indicating the position of the simulated aircraft. The phantastron delay circuit is synchronized with the time base producing the radial sweep on the P.P.I tube. Several simulators M may be employed with a single display unit N.
