Title: Rapid correction of steady state flight control system errors
IPC: G05D1/02
Filed: 1964-01-23
Abstract: 1,017,352. Automatic steering control. BENDIX CORPORATION. Jan. 23, 1964 [Jan. 30, 1963], No. 3041/64. Heading G3R. In an automatic steering control system for an aircraft or missile, control is effected by a signal dependent on displacement from a radiodefined course combined with a signal dependent on deviation from a heading parallel to the course an integral of the first signal being added automatically when the resultant of the above two signals has been below a predetermined value for a predetermined time. In Fig. 1, an aircraft is automatically maintained on a desired heading, e.g. parallel to a radio defined course, by signals from a reference device 47, e.g.a compass, which control steering means 54 through a control system 52. Then, to approach and follow the radio course, a gauged switch S 6  is closed manually so that a radio receiver 10, e.g. a localiser receiver, is energized from a source 21 and signals E 1 , representing displacement from course, are produced and applied to the control system. During this approach the beam displacement signal is applied to a unit 32, arranged as a synchronizer, which develops an output equal to its input by feedback through a contact 34. The beam displacement signal is also applied to a sensor 15.so that when it falls to a predetermined value a relay 64 is energized to close a contact 67 and thereby energize another sensor 60. The latter detects when the resultant signal applied to control system 52 falls to zero, possibly with the beam displacement signal balancing the heading deviation in a crosswind, and if this condition persists for a predetermined time, a switch S 4  operates to change unit 32 into an integrator and connect its output through a changed over contact 34 to the control system. Persistent displacement from the beam is then removed. Switch S 4  is mechanically self locking and must be reset manually. Sensor 60 may contain a filter to remove transients and the control system may include variable gain and limiting devices.

Abstract: 233,417. Willans, P. W. Feb. 6, 1924. Thermionic amplifiers.-Valve receivers of the reaction type are provided with means for neutralizing the distortion caused by the high selectivity or low damping of the receiving circuit. The back-coupled rectifying valve V has in its plate circuit a combination of resistance R, and inductance L1, both shunted by a by-pass condenser C1 and the audio-frequency voltage across the combination is applied to the grid of an audio-amplifier V1. If R be the effective resistance remaining in the receiving-circuit L C after taking account of the negative resistance introduced by the back-coupling, then exact compensation for distortion is produced by making the ratio of R1 to L1 half that of R to L. For supersonic reception employing two or more stages of selection and rectification. the compensation may be effected after each stage of rectification.

Jan. 29, 1960 [Jan. 31, 1959], No. 3259/60. Class 103(5). A railway vehicle automatic coupler carried by a bell cranked and forked lever 13 pivoted at 12 to the coupler head and at 14 to a draw hook 15, may be lowered to disclose the hook by operating one of two hand levers 33 on either side of the vehicle, the lever 13 being connected by an intermediate cranked and forked lever 16 pivoted to toggle levers 28 which are extended to form the hand levers. The side plates 18 from which the guides 19 extend are pivoted to the pin 14, and the two forks of the lever 16 are connected rearwardly by a pin 25 sliding within the slots 20 and mounting at its middle a vertical pin 26 on which the toggle levers 28 are pivoted. The guides 19 support transversely extending slotted members 21 which guide pins 29 extending vertically from the levers 28, and the pins 29 are connected top and bottom by tension springs 30. When the coupler is connected to a mating coupler and is given a buffing load the coupler will assume the dotted position shown in Fig. 1, the lever 16 and the pins 25, 26 being forced rearwardly against the action of the toggle springs 30. As soon as the buffing force ceases to act the springs 30 draw the pins 29 towards one another and move the pin 26 outwardly thus causing the lever 13 to swing upwardly about the pin 14 and raise the coupler head. To lower the automatic coupler to an out of use position, one of the handles 33 must be pulled outwardly to cause the pins 25, 26 to move towards the vehicle headstock and the levers 28 to pass over centre until the pin 25 abuts the ends of the slots 20, Fig. 3. Height adjustment of the coupler head is made by turning the screws 23 to pivot the side plates 18. The inside surface of the lever 13 is convexly curved at the pin 14 in order that the lever with the coupler head may be turned in the horizontal plane.
