Title: Track guidance apparatus for aircraft
IPC: G05D1/02
Filed: 1960-09-23
Abstract: 963,134. Automatic steering control of aircraft. SPERRY RAND CORPORATION. Sept. 23, 1960 [Sept. 23, 1959], No. 32765/60. Heading G3R In a system for automatically guiding an aircraft on to a predetermined track, signals dependent on attitude and position, of the aircraft relative to the track are combined in to different ways to control the aircraft according to whether the latter is approaching the track from a distance or is close to the track, changeover from the former to the latter mode occurring when a signal representing rate of change of displacement of the aircraft from the track becomes small. As shown, signals from a potentiometer 22, operated by a follow-up servomotor 14 in dependence on the output of a radio receiver 10 and representing magnitude of displacement of an aircraft from a radio beam, are applied through amplifiers 26, 30 to control ailerons (not shown) to bring the aircraft back on to the beam. A generator 18 driven by servomotor 14 develops signals representing rate of displacement from the beam which are applied to amplifier 26. Signals from the roll pick-off of a gyro-vertical 32 are applied to amplifier 30. When the aircraft is flying parallel to the beam and the rate signal from generator 18 is less than a predetermined value a relay 34 is de-energized. Under these conditions the rate signal is disconnected by the operation of contact 36, an integral component of control is introduced by the operation of contact 38, and a heading signal from a directional gyro 46 is applied to amplifier 30. A servomotor 50 maintains the heading signal zero during the period while it is not effective to control the aircraft.

Convention date, Nov. 26, 1932. [Class 106 (ii).] An echo-sounding device and a barometer act upon a common indicating mechanism which is first operated from the echo device and thereupon from the barometer. In the form shown in Fig. 1, the shaft 12 of the pointer 1 carries an iron disc 4 and is freely rotatable. A worm wheel 13 in one with slip rings 14, 15 is driven from a regulated electric motor (not shown). Pot magnets 3, 5 are loosely mounted on the shaft at each side of the disc 4, the magnet 3 being connected to the worm 13 and slip rings. On sending out the wave train, the magnet 3 is energized through brushes 16, 17 and the slip rings 14, 15, while the magnet 5 is energized by the returning echo wave. The magnet 5 is connected with the driving shaft 18 of the barometer. The latter consists of a pressure chamber system 6 which through a link 19 rotates a spindle 20 which through link 21 and lever 23 rotates the spindle 18. The pointer 1 remains at zero until the magnet 3 is energized on sending out a wave train when the disc 4 is attracted and carries the pointer with it. The reflected wave energizes the magnet 5 which now attracts the disc 4, and being connected to the chambers 6, these latter from now on move the pointer. The inside of chambers 6 is connected through a tube 25, 26 to a container 7 great in capacity compared with chambers 6. By means of the cock 28, the container 6 is normally placed in contact with the atmosphere, the cock being closed just before the echo measurement is carried out. In a modification, the pointer spindle is connected to the spindle 12 and barometer capsule through a differential linkage.

Abstract: 386,406. Cleaning bedpans. HELLYER, R. H., 35, Red Lion Square, London. Dec. 4, 1931, No. 33652. [Class 26.] Relates to a safety interlock device between the door 3, Figs. 2 and 3, of a chamber, such as the chamber for cleaning bedpans described in Specification 344,593, and a valve 11 admitting steam or hot water thereto, said interlock device ensuring that the door shall not be opened until the valve is closed, and preventing the opening of the valve until the door is shut. Fig. 3 shows the arrangement in which the door 3 is closed and the valve 11 has been opened by the rotary screwed spindle 12, 13, 15, operated by the handle 16. In this opening action a worm 20 has engaged behind a lug 21 on the door 3 which is thereby locked in the closed position. To open the door 3, the valve spindle is first rotated to close the valve 11, in which position the handle 16 abuts against a stop 25 and the worm 20 clears the lug 21 and releases the door. When the door is opened a cylindrical locking bolt 22 slides forward under spring action 24 and passes into a gap 20a in the worm and thereby locks the valve spindle in this closed position. In the act of closing the door again, the lug 21 abuts on the reduced outer end 28 of the locking bolt, which clears the periphery of the worm, pushing the bolt forwards so as to release the worm as the door closes, whereupon the spindle 15 is rotated to engage the worm behind the lug 21, lock the door 3 and open the valve 11. In Fig. 2 the hopper 1 with its drain trap 2 is shown, a treadle 10 being provided for withdrawing a bolt 5 and allowing the door to open by gravity, under dashpot control 9, when released by the interlock means described above.
