Patent GB-1131431-A (GB)
Title: Improvements in or relating to aircraft instruments
Inventor: BRADBURY PETER
IPC: G05D1/06
Filed: 1964-12-24
Abstract: 1,131,431. Aircraft instruments. SMITHS INDUSTRIES Ltd. Dec. 17, 1965 [Dec.24, 1964j, No. 52430/64. Addition to 1, 032, 466. Heading G1N. An aircraft instrument measures the difference between a first signal, representing the rate of change of pitch attitude of the aircraft, and a second signal, representing a function which is dependent upon both the forward acceleration of the aircraft (as in Specification 1, 032, 466) and also the extent to which the angle of incidence of the aircraft differs from a predetermined value. The two signals are compared in an amplifier 14, driving an indicator 15, the input of the amplifier receiving the first signal through a resistor 12 and the second signal through a resistor 10. The first signal is obtained by passing the output # of a pitch attitude gyro 2 to an amplifier 13 having a transfer function which produces an appropriate rate signal. The second signal is obtained by applying to the input 5 of an amplifier 8 both the output of a switch 7, and an acceleration signal from a summing unit 4 which combines the output of an accelerometer 1 with a signal derived from the pitch signal 6 to correct for gravity components in the accelerometer output. The output of amplifier 8 passes through a limiter 9. The wiper of the switch 7 is normally in contact with a resistor 16 which carries a signal representing the difference between a desired pitch attitude #d, preset at 19, and actual pitch attitude 6. When in the course of a landing manoeuvre it is decided to abandon the operation and to overshoot, a button 27 is pressed at the same time as engine power is increased. This causes the switch 7 to operate after a time interval set at 25. During the interval before the switch operates, the desired pitch attitude 6d required for safe overshoot should be achieved by the pilot, so that the indicator 15 for the remainder of the period directly compares the acceleration signal from 6 and the rate of change of pitch attitude signal from 12. When the switch 7 operates, the output of a unit 21 is added to the acceleration signal, this unit determining the difference between aircraft incidence angle α, measured at 22, and a required basic incidence angle preset at 23, the output of the unit 21 being further modified by a signal from 24 representing the flap-setting. The indicator 15, which comprises a rotatable cylinder carrying a helical band, then provides an indication in magnitude and sense of any departure of pitch rate from the value demanded by the signal from 10 for a required flight path following overshoot. The signal from unit 21 may be introduced slowly to avoid an undesirably large change in required pitch rate. A unit 28 monitors the inputs to amplifiers 8 and 14 to give an alarm if failure of any circuits cause erroneous indications, and also compares the output of pitch gyro 2 with a second similar gyro 2' to indicate failure of the gyro 2.

Abstract: 1362320 Photo-electrically detecting holes in webs H LIPPKE 17 Nov 1972 [18 Nov 1971] 53142/72 Heading G1A Holes in a web of material, e.g. paper, are detected by photo-electric apparatus comprising a substantially linear elongate light source (which may comprise a plurality of aligned sources), on one side of the material, and, on the other side, two rows of detectors, the axes of the rows and the light source being parallel and situated at an angle, e.g. at right angles, to the direction of movement of the web. The photo-detectors are connected in pairs, one detector from each row, such that an indicator device responds to the difference in the outputs of the detectors of each pair. By using elongated filament lamps having clear glass envelopes, the lamps and detectors may be spaced relatively far apart on either side of the web, and the holes in the web act as pinhole apertures to form an image 12 Fig. 2 of the filament in the plane of the detectors. Since such an image is incident on only one row of detectors at a time, a different output is obtained from detectors 11 than from detectors 12, Fig. 2, so that the difference signal as sensed by a differential amplifier, Fig. 4 (not shown) provides a fault output signal. The differential arrangements of photo-cells prevent ambient light variations affecting measurements, The apparatus may be shielded from external light.
