Abstract: An automatic gain control (AGC) apparatus for a digital receiver is disclosed herein. The AGC apparatus includes an adjustable gain amplifier having an input port for receiving an input signal, a control port for receiving a gain control signal, and an output port for providing an output signal. The AGC apparatus further includes a measurement circuit for generating a received power signal based on the power of the output signal. A saturating integrator compares the received power signal to a reference signal and generates an gain control signal in response to a result of the comparison. The saturating integrator includes a decision circuit for enabling integration based on values of the received power signal, the reference signal, and the gain control signal. In a preferred implementation the utilization of an input limiter in conjunction with an analog to digital converter enables accommodation of an increased input signal dynamic range. Accordingly, the AGC apparatus is capable of being used in digital demodulation of FM signals. The AGC apparatus may also be employed within a dual mode receiver designed to process both FM and code division multiple access (CDMA) input signals.

Abstract: 822,414. Converting. GENERAL ELECTRIC CO. Ltd. Jan. 11, 1957 [Jan. 11, 1956], No. 1036/56. Class 38 (2). A.C. is converted into D.C. pulsating at a lower frequency by rectifying the output of an induction regulator energized by the AC. and rotated at the lower frequency. The pulsating supply which may be converted to A.C. of the lower frequency may be supplied to a variable speed synchronous motor, as described in Specification 821,432. Fig. 1 shows three induction regulators 6, 7, 8 connected to three-phase supply 1 and driven by a motor 9 in such phase relationship that when passed through transformers 10, 11, 12 and bridge rectifiers 13, 14, 15 the output at 2 is D.C. with pulsations in threephase relationship. In a modification a single induction regulator has on the rotor three primary windings connected in star to the supply and on the stator three sets of three series-connected secondary windings, one winding of each set being reversed, the sets being mutually phase displaced and their outputs rectified by single-phase bridge rectifiers (Fig. 3, not shown). In the arrangement of Fig. 7 the three phase outputs from the frequency determining regulator 44 are connected to the star points of three-phase secondary winding groups 47, 48, 49 of a transformer 45 each group having a winding connected to one of the delta-connected primary winding groups of the three transformers 10, 11, 12. The outputs of the secondary windings are rectified at 13, 14, 15 and converted to A.C. by rotating commutators 50. Instead of commutators, electromagnetic interrupters may be used (Fig. 6, not shown). By providing further induction regulators between the three transformer secondary windings and the rectifiers, and omitting the inverting switches, the output may be given a sine squared waveform (Fig. 8, not shown).

Filed: 1957-01-16
Abstract: 841,211. Helicopters. VYZKUMNY A ZKUSEBNI LETECKY USTAV. Jan. 16, 1957, No. 1647/57. Class 4. Apparatus for stabilizing helicopters and for automatically regulating the collective blade pitch under conditions in which auto-rotation is required, comprises a vertical control bar for each blade, connected to the pilots' cyclic pitch control swash plate and to a pivotal joint within which slides a bar connected to the blade, the joint being linked to a flyweight arm rockable about a horizontal axis in dependence on the speed of rotation of the rotor. In Fig. 1, each blade 19 is pivoted to the hub (not shown) on a flapping hinge, and its pitch control lever 18 is joined by a link 17 to a crank lever 16 on a pin journalled in the hub and fast to a second crank lever 15. A pivotal joint 14 slidable on lever 15 affords pivots for a vertical bar 13 connected to the swash plate (not shown) and for a fork 12 pivoted to a lug 11 on an arm 1 bearing a flyweight and pivoted at 2 to a rod 3 slidably mounted in a sleeve 4 on the hub, radially outward movement being limited by a collar 5. A spring 6 extends between a flange on sleeve 4 and a flange on rod 3, the latter flange being connected by link 8 to one end of a two armed lever 7 centrally pivoted to the hub, the other end being connected to similar mechanism on the opposite side of the hub for a second blade (not shown). Lugs 9 (one shown) on each arm 2 are connected by a rod 10. If the helicopter changes its altitude, the plane of rotation of the flyweights is maintained, Fig. 2, and they flap with respect to the rods 3, rod 10 equalizing the flapping movements of the two weights. If the rods 13 from the swash plate are held fixed, each fork 12 oscillates radially and angularly displaces lever 15, effecting a stabilizing cyclic pitch correction, which tends to bring the rotor plane parallel to the plane of rotation of the flyweights as shown by Fig. 2. During normal flight, the centrifugal force on the flyweights urges the rods 3 outwards, compressing springs 6. In the case of engine failure, the rotor speed falls, the spring 6 extend, the forks 12 move inwardly, and the blade pitch is lowered to that suitable for auto-rotation. The corrections to the two armed lever 7 ensure that the pitches of the two blades are changed equally. The linkage 16, 17, 18 is such that upward flapping of the blade is accompanied by a decrease in pitch.
