IPC: G01S13/86
Filed: 1957-06-26
Abstract: 835,312. Automatic control systems for gyroscopes. GENERAL PRECISION LABORATORY Inc. June 26, 1957, No. 20236/57. Drawings to Specification. Class 38 (4). [Also in Group XL (c)] In an aircraft navigational system, speed and drift are measured by both a radar Doppler system and an inertial arrangement. The difference between the output signals of the two systems is employed to correct the long term errors of the inertial system. The latter consists of a horizontal platform which carries two accelerometers, the outputs of which produce an indication of linear horizontal ground speed, and three integrating rate gyroscopes. Deviations of the platform from horizontal and from the reference direction are detected by the integrating rate gyros mounted thereon. Drift of the platform from the reference direction, due to error of the corresponding gyroscope, is corrected by comparison with a magnetic or astro compass. The output signals of the two platform levelling gyros control the platform gimbal mounting through torque motors and are themselves precessed by the difference error signals to correct for frictional drift and earth sidereal rotation. Correction signals corresponding to the earth sidereal rate and Coreolis acceleration are derived. Each accelerometer consists of a cylinder mounted with its axis horizontal, in a supporting fluid. The mass of the cylinder is mainly below the axis and the resultant pendulum action is detected electrically by a device on the cylinder axis. Specifications 803,519, 803,520 and 804,060 are referred to.

Title: Improvements in and relating to control systems for power-driven movable objects
IPC: F15B13/16
Filed: 1943-12-03
Abstract: 613,805. Fluid-pressure servomotor-control systems; hydraulic pressure engines. POLSON, R. A., and METROPOLITAN - VICKERS ELECTRICAL CO., Ltd. Dec. 3, 1943, No. 20286. [Classes 69 (ii) and 135] In a control system for maintaining correspondence between a control member and a movable object driven by a liquid-pressure engine, a control member 24 is provided to affect the liquid pressure existing across the inlet and outlet ports of the engine so that it is greater for acceleration than for retardation. Fig. 1 shows the engine 1 controlled by a valve 18 that is actuated through a servomotor 13, incorporating a spring 16 and a dashpot 17, controlled by an element 11 responsive to lack of correspondence between the movable object and the control member and derivatives of this value; the valve 18 controls the volume of liquid to the engine 1. An element 31 responsive to the same variables as element 11 controls a valve 24 through a servomotor 28; this valve controls the inlet and outlet passages 22, 23 of the engine so that when the valve 18 is moved to cause a retardation of the engine, the valve 24 moves to open to exhaust the passage serving as the inlet and reduce the pressure difference across the engine. When the valve 18 is moved to accelerate the engine, the valve 24 is moved to open the exhaust passage and thus increase the area of exhaust opening and increase the pressure difference across the engine. The valve 24 may have additional control surfaces to allow pressure liquid from pipe 32 to enter the appropriate passage to assist in obtaining the desired pressures. Fig. 4 shows an arrangement where the valves 18, 24 are controlled from a single element 11<1> responsive to the same variables. The movement of the element 11<1> is amplified by the servomotor 42 which is connected to the lever 47. A link 49 connects the lever 47 to the lever 50 of a servomotor 28 actuating the valve 24. The valve 18 is actuated by a servomotor 13, a lever 53 being connected to the control valve and pivoted at 52 to the lever 50, and the rod 14a being connected to the pivot 52 by a lever 62 and link 63; the end of the lever 47 is connected to a spring 16 and by a dashpot 17 to the lever 62. The dashpot 17 influences the return to central position of the control valves of servomotors 13, 28 according to the speed at which the valves 18, 24 are moved by the servomotors. The end of the lever 53 is forked and the pivot pin 55 is adjusted by a cam 59 actuated by a pinion and rack on the rod 14a. The cam is shaped so that the travel of the valve 18 is reduced as compared with the travel of the valve 24 and its effect is to cause acceleration of the movable object to be more closely dependent on the lack of correspondence between the movable object and the control member. Specification 592,208 is referred to.

Abstract: 243,449. Smith, R. T. Aug. 29, 1924. Directive signalling; bearings, determining.- To enable an aircraft to determine when it is close to, or immediately over a wireless transmitting station, it is provided with an aerial coil arranged in a vertical plane and continuously rotated about a vertical axis. The strength of received signals tends to equality for all positions of the coil as the aircraft. approaches the neighbourhood vertically above the transmitter. In an alternative form, the invention is utilized in conjunction with the direction-finding system of Specification 134,560, in which system two vertical coils, a main coil and an auxiliary coil, were fixed to each other at right angles and were rotatable about a vertical axis. Switching means were provided for reversing the series connection between the coils, and when this reversal produced no effect on the signal strength, one of the coils was receiving no wave energy, and its plane was therefore at right angles to the direction of the transmitter. To remove, the ambiguity of 90‹, second switch was arranged to cut out the auxiliary coil, and to replace, it by an equal inductance, so as to avoid alteration of the tuning. If the main coil gave signals, its plane lay in the direction of the transmitter. For the purpose of the present invention, the second switch is arranged to cut out the main coil and to insert an equal inductance in series with the auxiliary coil. While the aircraft is flying towards the transmitter, but is still distant therefrom, its direction is ascertained by obtaining equality of signal reception for the two positions of the reversing switch, and by obtaining zero or minimum signals on the auxiliary coil alone, which then lies across the direction of the transmitter. As the aircraft approaches the transmitter, the signal heard on the auxiliary coil alone increases in strength, and when immediately over the transmitter, the three signals heard (a) with the auxiliary coil alone, (b) with the two coils in series, (c) with the two coils in opposition approximate to equal intensity. An automatic switch for effecting the circuit changes is described in Specification 243,448. The Pro- (visional Specification refers to a modified arrangement in which a single vertical coil is fixed in a transverse plane on the aircraft, the received signals increasing to a maximum as the aircraft approaches a position over the transmitter.
