Patent GB-910231-A (GB)
IPC: G05D1/00
Abstract: 910,231. Aircraft instruments. KOLLSMAN INSTRUMENT CORPORATION. Oct. 31, 1958 [Jan. 24, 1958], No. 34992/58. Class 4. An aircraft take-off indicator comprises means for indicating the instantaneous airspeed required for the aircraft subsequently to reach a predetermined take-off speed in a predetermined time, means for driving the indicating means as a function of time, and further means for indicating the measured instantaneous airspeed. In Fig. 7, a spring driven clocktype mechanism 80 with a starting solenoid 81, drives a shaft 82 on which is a rate controlling means 84, and which operates a synchro 94. Therotor of a further synchro 76 is driven by a motor 72 energized by amplifier 74. The motor also rotates the stator of a synchro 78, the rotor of which is driven by a pitot-static diaphragm 60 through linkage 62, 64 and gears 66, 68. An indicated airspeed pointer 38 is driven over a fixed scale 37 by gear 68, and a ring gear 42 is driven by motor 72 through gear 70. Ring gear 42 has an inwardly projecting marker 48. The output signals of an angle of attack responsive device 98, and the synchro 78, are connected in series to one fixed contact 92 of a switch 95, and the output signals of synchros 94 and 76 are connected in series to the other fixed contact 90. The movable contact 97 is connected to amplifier 74. Before take-off, the pilot rotates an arm 88 to the position T.O., abutting stop 91. This winds the spring of mechanism 80 and closes contact 97 on contact 90. Further, he adjusts the rate mechanism 84 by a knob 50 until a pointer indicates on scale 56, the known acceleration required if take-off speed is to be reached in the distance available. The clock mechanism 80 is released by solenoid 81 by closure of a number of switches such as 81a, these being closed under the conditions: pilot's manual start control operated, wheel brakes off, and engine throttles open. The marker 48 is then driven in corresponence with the rotation of shaft 82 by motor 72, lack of correspondence being detected by comparing the signals from synchros 94 and 76, and feeding the resultant over contacts 90, 97, to amplifier 74. By comparing the positions of marker 48 and pointer 38, the pilot can see whether his actual indicated air speed is above or below that required at any time during the take-off run. Non-linear transmission means, such as cams, may be utilized when the aircraft does not normally accelerate uniformly during take-off. After take-off, arm 88 is rotated manually or automatically to the position A/A abutting stop 93, closing contact 97 on contact 92. Ring gear 42 is now driven relatively to pointer 38 in accordance with the angle of attack, by comparing the signal from device 98 with that from synchro 78, and feeding the difference to amplifier 74. Ring gear 42 has other markers, not shown, representing approach and stalling angles of attack. Preferably, a further pointer, not shown, coaxial with pointer 38, indicates the maximum permissible airspeed at any time on scale 37. Knob 50, scale 56, and means for operating arm 88 are all mounted on one escutcheon.

Abstract: In order that the triggering and time sequence of a coupling or decoupling process of a mechanical central buffer coupling 1 and an electrical cable coupling 2 arranged on said central buffer coupling so as to be longitudinally displaceable in the direction of the coupling axis can be coupled with a common rotary drive, in an operationally reliable fashion, a coupling and decoupling device comprises a driveable shaft 15 which extends at right angles to the coupling axis and to which an actuating arm 19 is attached for rotation, which actuating arm engages into a guide rail 21 of the cable coupling. The shaft 15 also extends through a sleeve 7a which carries an operating member 25 for the unlocking of the mechanical buffer coupling 1 and rotates this via a coupling member 7b fixed to the shaft 15. Axial movement of shaft 15 against spring 18 moves coupling member 7b to disconnect the shaft 15 and member 25, the shaft remaining rotationally coupled to 19. <IMAGE>

Title: Door structure
Inventor: PENDERGAST STEPHEN ROY
IPC: E06B3/70
Filed: 1993-06-22
Abstract: A door is formed by co-extensive skins (10, 12) of metal sheet which are arranged substantially parallel to each other. Each skin (10, 12) is formed as an open ended tray having two opposing edge margins (16, 18) deflected substantially at right angles to provide lips at those opposing edges. The lip (16) of the skin (10) is itself further folded over inwardly of the tray through substantially 180 DEG . The lips (16, 18) are in each case directed towards the respective other skin (12, 10) so that once the trays are fitted together the overlapping lips (16, 18) provide a reinforced edge face to the door, comprising three layers of metal sheet. This may make the door more resistant to impact damage and forced entry. A material such as a honeycomb lattice of cardboard or wood (14) may be arranged in the space between skins (10, 12). In other examples doors comprise three co-extensive metal skins arranged substantially parallel with spaces between them. <IMAGE>
