Title: Storing Element for Analog Values
IPC: F15C4/00
Filed: 1966-10-06
Abstract: 1,166,674. Fluid amplifiers; fluid-pressure servomotor systems. SUNVIC REGLER G.m.b.H. Oct. 6, 1966 [Oct. 9, 1965 (2)], No. 44727/66. Headings G3H and G3P. A control pressure is set up in a chamber 11, and output conduit 14, Fig.1, by a slack diaphragm 7 controlling a leak-off 16 from the chamber which is supplied through a restrictor 13. The diaphragm 7 is loaded by a pressurized body of liquid enclosed by a resilient metal diaphragm. This liquid can be placed in communication, through a valve 9 and a laminar restrictor (not shown), with a second body of liquid enclosed in a chamber 3b between a partition 2 and another slack diaphragm. Thus with valve 9 open an input signal pressure at 5 is copied in 1:1 ratio at the output 14. The input signal can be stored by closing the valve 9 through a pressure actuator 10. In an auto-manual control for adjusting the flow through a line valve 19 the line pressure or some other characteristic transformed into pressure, is applied to a pneumatic controller 20. Changeover cocks 31, 40, 47, 49, and 51 can be set in the auto position, Fig. 3 (not shown), by a rocker 48, or in the manual position, Fig. 2. In manual position, the actual valve input of controller 20 is indicated on a scale 31 and goes through cock 25 to a booster 27 similar to the device of Fig. 1. The nominal valve output 28 to controller 20 is indicated on a scale 33. This is in 1:1 ratio and the controller is ineffective but is also isolated from servo-valve 19 by cock 31. A third scale 35 shows the servo pressure. A second booster 37 has a stored input obtained by adjusting plus and minus keys 44, 45 and closing the valve 9, Fig. 1. The set output goes through a third booster 39 in 1:1 ratio to the servo-valve. In auto position, Fig. 3 (not shown) the valve 9 of booster 27 is closed to store the last present input valve, which controls the servo-valve 19 through controller 20 and cock 31. Booster 27 is now connected with the plus-minus keys 44, 45 through cock 49 so that the operating point can be adjusted. Boosters 37, 39 are isolated by cocks 40, 47. A number of line valves (70, Fig. 5, not shown) in different systems, can be controlled according to a programme by a single pneumatic controller (63) to which the corresponding number of nominal and actual valve inputs are selectively fed. The line valves are operated through individual boosters (1" to 5") of which one at a time is in open 1:1 ratio connection with the controller whilst the others operate on the last stored signal. In a pneumatic analog computer arrangement, Fig. 6 (not shown), variables Pe1 to Pex are fed to a controller (82) actuated through a recorder (81) by a pneumatic programme tape reader (80). The selected output is fed to an analog computer (86) and thence to an output storage element (87) and utilization points (88). The outputs are cyclically corrected. In the time between corrections, the value in the element (87) is maintained through an intermediate memory (84) which feeds back to the controller (82).

Abstract: 1,044,946. Automatic landing of aircraft. SMITHS INDUSTRIES Ltd. Jan. 18, 1963 [Dec. 20, 1961], No. 45737/61. Heading G3R. [Also in Division H4] During the flare-out phase of an automatic landing system the pitch control surfaces of an aircraft are automatically controlled by a signal representing error from an exponential path and by a nose-up signal which varies with time. The invention is applied to an aircraft automatic landing system of the type in which the aircraft is steered towards a radio glide path which it follows down to a predetermined altitude from which descent is continued by maintaining constant attitude and airspeed. At a second lower predetermined altitude, exponential descent commences. The control signal for this developed from the output of a radio altimeter by RC circuits associated with negative feedback magnetic amplifiers. This control signal, which is limited by rectifiers, and an additional nose-up signal, which is derived from a constant voltage source through RC networks associated with transistors, are applied to separate control windings of a magnetic amplifier in the elevator control system. The latter may be a positional or rate/rate servo-system, may be triplicated, and may include a hydraulic actuator. The introduction of the nose-up signal may be delayed a little by a timer. Control of engine throttles as well as elevators is referred to. The aircraft may be guided in azimuth by radio or leader cable control during the constant attitude and exponential descent. Finally, at a very low altitude the aircraft heading aligns with the direction of the runway. Mathematical formulae are given for suitable components of control.

Abstract: 1400844 Level and curvative of railway tracks FRANZ PLASSER BAHNBAUMASCHINENINDUSTRIE GmbH 5 Oct 1972 [8 Oct 1971] 45883/72 Headings G1A and G1F [Also in Division B7] In an arrangement for determining or correcting the deviation in the position of railway track in which a reference beam of radiation e.g. a laser beam 7 is directed from a transmitter 6 parallel to the required position of the track past a position at which deviation is to be determined or corrected to a measuring board 11 or radiation receiver, a beam deflecting element is provided at the said position which deflects the beam when any track deviation is encountered. In the levelling arrangement shown in Fig. 1, the beam 7 fans outwards in a horizontal reference plane parallel to the required track plane and the beam deflecting unit is a cylindrical lens 9 having its axis horizontal and extending in the reference plane when the unit is over correctly positioned track. In this latter condition the beam is undeflected and it strikes the board 11 at a predetermined position. Track deviation is measured by the distance the deflecting unit has to be moved to bring the deflected beam to the predetermined position. During track levelling this movement occurs as the track is lifted by track levelling tools. For track alignment a beam which fans in the vertical plane and a cylindrical lens with a vertical axis are used. In the combined levelling and aligning arrangement shown in Fig. 9, laser beam 31 has a crosssection in the form of a cross and is directed, with its horizontal component 31a parallel to the required track plane and its vertical component 31 extending in line with the required alignment of the track, from transmitter 29 via beam deflecting spherical lens 30 at the track position being corrected to a beam sensitive receiver 20. The receiver, Fig. 5, includes light and/or temperature sensitive elements 23 disposed as shown which co-operate with the vertical component 21 of the beam to detect any lateral deflection arising from an alignment error to control tools for track alignment and with the horizontal component 22 of the beam to detect any vertical deflection due to level error to control tools for track levelling. For correcting track in curves, Fig. 6, the beam is directed tangentially to the track from transmitter 15 and deflected by cylindrical lens 17 to measuring board 18. Depending on the distance between points 2, 3 and 4 and the track curve radius the position the beam strikes the board can be determined and if necessary the track at position 3 and the lens are shifted to make the beam strike the board at this position.
