Title: Automatic pilot effecting controlled speed followed by asymptotic approach to selected altitude
IPC: G05D1/06
Filed: 1964-10-01
Abstract: 1,013,869. Automatic control of aircraft. SPERRY RAND CORPORATION. Oct. 1, 1964 [Oct. 15, 1963], No. 40064/64. Heading G3R. In a system for automatically controlling asymptotic approach of an aircraft to a selected altitude the altitude of the aircraft is controlled by the difference between actual and desired rate of change of altitude above a predetermined altitude and the difference between actual rate of change of altitude and altitude error below the predetermined altitude. As shown, a desired rate of change of altitude of an aircraft in selected manually by a wheel 30 so that a potentiometer 31 produces a corresponding voltage which is compared at 35 with a voltage on line 13 representative of the actual rate of change of altitude, and any difference is effective to adjust elevators 19 which are also controlled by signals from pitch attitude and rate gyros 21. Rate of change of altitude is thus maintained at a desired value. A signal on line 12 responsive to actual altitude is compared by synchros 22, 23 with the desired altitude set by a knob 24 so that a signal representing altitude error is applied through an amplifier 26 for comparison at 27 with the set rate of change of altitude. When these two signals are equal at a predetermined distance from the desired altitude a null detector 32 changes over switches 33a, b and energizes an electromagnetic clutch 34. As a result, the elevators are then controlled by the difference between the actual rate of change of altitude and the altitude error to give an asymptotic approach to the desired altitude. At the same time the signal representing actual rate of change of altitude is applied to a servo-system 41 so that wheel 30 is reset to zero by the time that the desired altitude is reached. When at zero, wheel 30 operates a switch 42, 15 to change over control of the elevators to an altitude error signal on line 14 so that the desired altitude is thereafter maintained automatically. Switch 42 also resets null detector 32 in readiness for selection of a new altitude.

Abstract: 1,185,018. Photo-electric spectro-photometers. EVANS ELECTROSELENIUM Ltd. Sept. 4, 1967 [Sept. 9, 1966], No. 40329/66. Heading G1A. A photo-electric specrro-photometer comprises means for taking samples of liquid at predetermined intervals, means for projecting a beam of light through the samples, a photo-electric element to receive light from each sample to produce a voltage logarithmically related to the optical density of each sample, an electronic chopper connected to the photo-electric element to form a rectangular wave an amplifier for the rectangular wave, a differentiating circuit connected to the amplifer output a trigger circuit providing an output whenever the differentiated voltage is above a pre-set level and means for integrating the output of the trigger circuit and digitally printing out the integrated value. A spectro-photometer comprising a controlled light source 11 directing a beam through a cuvette 19 on to a photo-multiplier 20 is controlled by cam operated switches in a timer 21, samples being drawn up from a container 30 by a syringe 24 which also serves to send a cleansing air stream back through the cuvette when the sample is discharged. The photomultiplier is fed from a stabilized E.H.T. source and its output, smoothed by a capacitor, is chopped in a unit 43 to produce after amplification and differentiation pulses of constant height the widths of which are proportional to the photo-multiplier output. The pulses are integrated, and the resulting voltage is compared in 53 with a voltage from a potentiomenter 54 which is driven to balance by a servo-loop. The potentiometer drive also sets a counter, the setting of which is printed out together with a serial number, and between measurements the potentiometer and counter are returned to a mid-position. The apparatus is arranged to be automatically recalibrated at intervals with a standard liquid in the cuvette, the printing arrangements being suppressed during such calibration. Container 30a may be a channel conveying a flowing liquid.
