A gyro having two degrees of freedom comprises a rotor 12 with a spin axis 22, a shaft 14 having an axis 24 intersecting the axis 22 to form a tilt angle 30, auniversal joint connection 16 between the rotor and the shaft for tilting the rotor axis in any direction and the rotor having a rim 40 which includes an annular permanent magnet 110, the magnet also being part of a torquer 32 in order to minimize the ratio of the gyro weight relative to the output power of the torquer. The shaft, which is mounted in bearings 76, 78, is driven by an electric motor 18 having a stator 58 and an armature 60 fixed to the shaft. The rim 40 of the rotor comprises a channel shaped annular magnet, the sides 46, 48 of which act as flux return paths for the flux from the magnet 110. A retaining ring 112 supports the magnet against the side 46. The torquer coils 102 are mounted on a support ring 88 and comprise two pairs of diametrically opposed coil systems. Each pair of coil systems tilt the rotor about an orthogonal axis perpendicular to the axis 24. The amount of tilt is detected by a system of four pick off coils 34, two of which 94, 98 are shown. A magnetic ring 90, secured to the rotor, forms a flux return path for the pick off coils and a shield 114 prevents flux from the electric motor and pick-off coils disturbing the torquer.

Title: Noise reduction system and apparatus using a compression and ex pansion system
IPC: H03G9/18
Filed: 1971-06-04
Abstract: 1356848 Compandors NIPPON VICTOR KK 4 June 1971 [5 June 1970 (2) 26 June 1970 27 June 1970 31 Aug 1970] 18976/71 Heading H4R In a compander system a compressor compresses the amplitude of signals in a frequency band smaller than the total pass band of the system using a compression circuit in the forward path of an amplifier, while the expander expands the amplitude of signals in the frequency band compressed by the compressor, using a similar circuit to the compressor connected in a negative feedback circuit of the expander. Variable impedance circuits in the compressor and expander can be arranged to compensate for non-linearity or supply voltage variations. Fig. 6 shows a preferred embodiment including a bridge circuit 150 in the forward path of the compressor 20, and a similar bridge circuit 190 in the negative feedback path of the expander 21. The bridge circuits have frequency selective circuits 151 or 188 in the diagonal arm so that it has no effect when the bridge is balanced, e.g. at high signal levels. A control signal, derived from the output of the compressor and input of the expander, varies the impedance of the parallel connected NPN and PNP transistors to unbalance the bridge and provide compression and expansion of the frequencies selected by the tuned circuit 151, 188, as the signal level is reduced. Use of the parallel NPN and PNP transistors improves the linearity with respect to signal level of the variable resistance provided thereby, while an alternative variable impedance circuit, Fig. 15, uses an f.e.t. provided with variable bias from silicon diodes 223 and 224, which, in combination with a bias applied to the amplifying transistor 226 preceding the control signal rectifier 225, compensates for supply voltage variations.
